I studied abroad in modern times

In the alchemy cauldron, the heavenly and earthly evil spirits were boiling, colliding, and exploding.

Outside the alchemy cauldron, the spellcasting movements of the group of disciples of the Jiushan Sect were unfamiliar, messy, and eye-catching.

But Madam Xuanhua did not move her eyelids, her eyes were fixed on the alchemy cauldron.

The expression on her face flickered with the light and shadow in the alchemy cauldron.

The feeling in her heart was more like the sound coming from the alchemy cauldron:

Crackling, dingling, dong, as if it was going to explode.

Didn't she understand what Zheng Fa was doing?

Of course she could understand.

But the problem was that she understood too much!

Refining external elixirs was not a difficult task for her. She had also practiced a lot for others, and she was very familiar with the process:

First, you have to prepare a good alchemy cauldron. The shape, pattern, and material of the alchemy cauldron cannot be wrong at all - it requires a skilled refiner to make it.

Some skills may be said to be less, and only a refiner in the Jindan period has this ability.

Then, you have to be proficient in various methods.

No, it's not just about being skilled, you have to form an instinct.

Generally, to have this level, you must at least have the strength of a golden elixir or a primordial infant.

She also knew that some people might have to bathe and fast before refining this kind of treasure to calm their minds, or even obtain a kind of blessing from the dark...

But what did Zheng Fa do?

A thing that is so ugly that it can't even be called a cauldron.

A group of disciples who don't seem to have mastered the outer alchemy method at all.

If these people were her disciples, she wouldn't let them do this job!

It's like building a house for ordinary people. You have to lay the foundation, then you have to find wood for beams, transport soil and stones for walls, and hire bricklayers and carpenters...

But how did Zheng Fa do it?

He pointed to the mud nest that your three-year-old child made yesterday and told you that the house was built.

The most important thing is that it can really be lived in!

Looking at the familiar flames of the cauldron, Madam Xuanhua couldn't help but cover her chest.

"What's wrong?"

Xiao Yuying asked on the side.

Madam Xuanhua didn't say anything, but continued to watch Zheng Fa and the others' actions, as if she was expecting something, and also seemed to be afraid of something.

She didn't say anything, but Xiao Yuying spoke again:

"I understand too."

"Hmm?"

Madam Xuanhua couldn't help but turn her head to look at Xiao Yuying.

"It has been broken."

"..."

...

Zheng Fa didn't have time to pay attention to the two spectators, and his eyes were also fixed on the alchemy cauldron.

This time, Zheng Fa roughly divided the alchemy team into three parts, corresponding to three levels.

Senior Sister Zhang has a very high control over the vitality of heaven and earth, and is responsible for the first level - controlling the energy of the heavenly Gang and the earthly evil.

Because of the profound thunder method, the master is responsible for the second level, which is the most important content - controlling the fusion and fission process.

Zheng Fa is guarding the last level and mixing the new particles.

They didn't do anything, but just stood aside, responsible for the bottom line for these disciples.

After all, it is a nuclear reaction...

To a certain extent, Zheng Fa also regarded this experiment as an opportunity to train these disciples.

Uncle Pang's eyes flashed with silver light, and he stared at the reaction in the alchemy cauldron carefully, shouting:

"Group 1!"

"Group 2!"

"..."

He had a keen eye, and the method of connecting talismans further trained his control of timing. It can be said that Uncle Pang was the metronome of the entire experiment.

Madam Xuanhua felt that they were just children playing in the mud.

But Zheng Fa knew how much the people in Jiushan Sect had prepared for this moment...

The spells in their hands were simple, but the cooperation with each other was not simple.

From the three supreme elders to every disciple of the project team, they were familiar with what they were going to do thousands of times in their hearts.

Just the connection between the groups, they tried for dozens of days like training relays.

Bathing and fasting?

Is it respect for refining external elixirs?

No.

The respect of Jiushan Realm is training again and again, cooperating again and again, pursuing practice makes perfect, until every second is accurate.

There is no metaphysics, only precision.

…

Three days later, the faces of all the disciples in the project looked pale, dry and tired.

But the light in their eyes was brighter than the "Shenxiao Wai Dan" in the alchemy furnace!

At the moment when the Wai Dan was formed, the yard was silent.

Even the breathing was very light, as if they were afraid of shattering the rumored indestructible Wai Dan.

Zheng Fa looked around.

Everyone's eyes seemed to fall on him.

With one move, the Shenxiao Wai Dan fell into his hands. He could sense the power of it through the thick Dan Sha.

"I declare that the Shenxiao Wai Dan was successfully refined for the first time!"

Everyone laughed.

Zheng Fa continued: "This shows that the fundamental principle of our "Golden Dan Project" is correct!"

This is why he refined this Shenxiao Wai Dan - compared to the Shenxiao Wai Dan itself, this is more like an experiment to verify his previous conjectures about the Golden Dan.

"This also shows that you..." Zheng Fa looked at the group of tired disciples and said in a louder voice: "Great."

The disciples were stunned. They didn't expect the headmaster to praise them first.

"Sister Zhang and I just put forward some ideas, talked about a few ideas, and maybe told you some principles."

"But..."

The Shenxiao Golden Pill in Zheng Fa's hand rose slowly, shining on every disciple who participated in the "Golden Pill Project".

"Jin Fan, you blew up your house to practice the second method... If it weren't for your good luck, I'm afraid you would be seriously injured."

"Zhu Hui, you are from the Hundred Immortals Alliance, but you have no prejudice. You are willing to teach others what they don't know. I have learned a lot of knowledge about refining from you..."

"Mu Qingyan... You are the great contributor to this project. You have proposed many ideas to solve the problems and contributed several secret methods..."

"..."

Zheng Fa counted them one by one, almost everyone's where they came from, what contributions they made, and how much effort they made in private.

He seemed to know everything.

Senior Sister Zhang looked at Zheng Fa and couldn't help but laugh softly.

She remembered what Zheng Fa said to her privately before:

"External pills are treasures in the eyes of cultivators in the Xuanwei Realm and are a helper for cultivation... Then this group of disciples are my external pills. If they are cultivated, they will illuminate the entire Jiushan Realm."

It can be seen that Junior Brother Zheng's words were not deliberate, but more like an emotional outburst under excitement.

After Zheng Fa finished speaking, he smiled again and said, "I am too long-winded, and everyone is tired... Sister Zhang will distribute the good deeds and rewards to you in the future."

"Go back and rest."

...

After the disciples left, Madam Xuanhua took Xiao Yuying to Zheng Fa.

"Madam?"

"I want to learn the "Golden Elixir Project". I wonder if Master Zheng agrees?"

Zheng Fa pondered for a while and said honestly, "The "Golden Elixir Project" seems to be a course, but in fact, you need to learn other knowledge first."

Madam Xuanhua also looked at the course schedule and understood it as soon as she heard it.

"What's the cost?"

Zheng Fa smiled, and there were only two words in his expression - add money.

Madam Xuanhua thought about it, and suddenly gritted her teeth and said, "What if I am the same as Yuying?"

"Hmm?"

"I can teach the "Weapon Refining Method" in Jiushanjie."

Zheng Fa's eyes lit up at once.

He adopted the model just now, to be honest - it was also because the level of weapon refining and alchemy in Jiushanjie was too low.

It can also be seen from the quality of this Shenxiao Waidan:

He has simplified the process as much as possible and reduced many of the requirements for operation.

But the Shenxiao Waidan he refined can only be compared with the lowest quality Jindan, which is far inferior to Madam Xuanhua's craftsmanship.

What's more, the traditional refining technique does not conflict with Zheng Fa's concept, but is the best nutrient...

Seeing his expression, Madam Xuanhua said again: "The tuition fee you mentioned... plus I will give you some spirit stones, should it be enough?"

Speaking of spirit stones, her face was full of heartache.

Zheng Fa nodded and calculated in his heart-good guy, this Madam Xuanhua seems to be paid to work?

Thinking of this, he still has some subtle apologies in his heart...

But whether it is "Jindan Engineering", "Electromagnetism", or even "Mathematics"...

I am afraid that a "Refining Method" is indeed not equivalent.

Not to mention other things, there are more than one master of refining, but the one who can learn this knowledge, at least in the Xuanwei Realm, is the exclusive Jiushan Sect.

Thinking of this, Zheng Fa felt quite justified.

On the side, Xiao Yuying smiled and then stopped smiling...

She stared at Madam Xuanhua, frowning, with a sentence written on her face:

We are all migrant workers, why are you so stubborn?

...

Mu Qingyan rested hard for a few days.

"Bang bang bang!"

The door was knocked hard.

When the door was opened, it was the senior sister from the same courtyard.

"Qingyan! Hurry up!" The senior sister's face was very red, her eyes were very bright, and her tone was very urgent.

"Senior sister?"

"Go to the Qunxian Temple!"

When she heard the senior sister's words, her heart jumped, as if she understood something.

She did not doubt the news of the senior sister - compared to her being alone because of the secret, the senior sister's lively and enthusiastic personality made her have many friends in the Baixian League.

Now she has also met many people in Jiushan Sect.

The senior sister pulled her and rushed all the way into the Qunxian Temple.

Sure enough, there was a group of statues in the Qunxian Temple.

This statue has the most people and the most magnificent momentum - a group of people stood, looking up, looking at the round Shenxiao Waidan on their heads, as if looking at the rising sun.

Mu Qingyan saw her own face in the crowd.

She smiled like everyone else, and seemed to have no thoughts at all.

"Qingyan?"

"Hmm?"

"The way you smiled just now really looks like this statue!"

"..."

Mu Qingyan was stunned for a moment, as if she was thinking about something, and she didn't say anything along the way.

After returning to the house, she tossed and turned in the room, thinking about it day and night, and didn't close her eyes for two days and two nights. Finally, she walked out the door, crossed the Rainbow Bridge, stepped onto Wanxian Island, came to the door of the headmaster's courtyard, and knocked on the door.

"Mu Qingyan?"

Seeing that she came to find him, Zheng Fa seemed a little surprised, but still let her into the yard.

Mu Qingyan whispered: "Disciple has something to report to you privately, the headmaster."

Zheng Fa glanced at her, nodded, and the two walked into the study.

After entering the room, the two of them fell into silence, and Mu Qingyan's face was full of confusion.

Zheng Fa didn't seem to be in a hurry and didn't urge her.

After a long time, Mu Qingyan said: "Master, I know... information and news about a secret realm."

She was quite nervous after saying this.

She went to Zheng Fa, first of all, in order not to waste the knowledge in her mind.

Just like Xiao Yuying said, she might lose more if she went out.

Especially after the success of the "Golden Elixir Project", she became more and more aware of this.

What Xiao Yuying said at that time might be extremely correct!

But in Jiushan Sect... she could only watch helplessly as she missed some opportunities.

She also felt it was a pity.

She had been thinking for a long time about revealing some opportunities to Zheng Fa and Jiushan Sect:

The best thing would be to get some resources in return.

At the very least, although she could not get anything, it was also a kind of return to Jiushan Sect - after all, she was a Yuanying, and understood the value of some of the Jiushan Realm courses better than others.

The most typical one is the "Golden Pill Project".

The hesitation was naturally due to insecurity or even distrust of Jiushan Sect.

It can even be said that with such a big secret, she didn't even dare to sleep with others, let alone trust or not.

Until now, she only dared to reveal the information of a secret realm.

Even, if it wasn't in Jiushan Sect, if it wasn't the "Golden Pill Project", Qunxian Temple.

If it was still in Baixian League.

She didn't dare to say a word.

Zheng Fa looked at her, as if he was thinking about something.

Mu Qingyan became more and more nervous.

Zheng Fa suddenly turned around and took out a large stack of documents from a shelf nearby.

"Take a look."

Mu Qingyan looked down and saw the words "Archaeological Project Book Template" written on the cover of the document.

She had a strange feeling in her heart. When she opened it, she found that it contained various project processes, including precautions for each link and the reward mechanism for good deeds.

Mu Qingyan looked at it for a long time and suddenly understood what the headmaster meant:

"Is this considered... data collection?"

She thought about it and asked.

Zheng Fa nodded and said, "Speaking of which, you are not the first disciple who said that he has secret realm information. Our disciples of Jiushan Sect also have opportunities. Oh, Xiao Yuying also talked about this matter."

"..."

Mu Qingyan felt that she was about to let out all her breath... The headmaster didn't seem to care too much about her information.

"You provide the corresponding information, and we will conduct a value assessment. If this project is launched, we will give you a certain amount of good deeds according to your information."

"That's the rule."

"If you think the good deeds are too little, keep the information. If you think it's enough, then inform the sect."

Zheng Fa's words have a sense of official business, but Mu Qingyan feels relieved for some reason.

She is very interested in this project book, and asked again: "Then... who will go to the secret realm?"

Zheng Fa did not hide it from her: "I want to cooperate with Fairy Xiao. We will provide intelligence and analysis, and she will lead the team entering the secret realm..."

"This...Is Fairy Xiao willing?"

Mu Qingyan asked.

Zheng Fa shook his head, not quite sure.

To be honest, the risk of going to the secret realm is the greatest, and Xiao Yuying is not short of secret realm information...

If Jiushan Sect did not have some analytical ability, he would not have the confidence to persuade Xiao Yuying at all.

Seeing his expression, Mu Qingyan suddenly gritted her teeth and said, "Master, I know that secret realm very well..."

"Hmm?"

"Moreover, it is rumored that the secret realm is related to Venerable Tianhe..."

Zheng Fa's eyelids jumped, and he looked at Mu Qingyan with some surprise.

He understood what Mu Qingyan meant-the more you know about the secret realm, the less dangerous it is to enter the secret realm, and the greater the possibility of getting good things.

On the other hand, what kind of person is Venerable Tianhe?

The value of the secret realm related to this person can be imagined.

I am afraid that Xiao Yuying will be tempted by this kind of information...

It's just...

He looked at Mu Qingyan, and his mind was full of thoughts.

Mu Qingyan lowered her head and grinned, cursing herself: Do you really think you are a member of the Jiushan Sect? You can also say this?

Unexpectedly, Zheng Fa was silent for a while, and then spoke: "Follow the rules, write down what you know in general, and if you are worried, don't write secret things."

Mu Qingyan couldn't help but look up suddenly.

See Zheng Fa nodded at her.

…

When walking back, Mu Qingyan's mind was even more confused-

What if the head didn't see anything wrong?

Definitely not.

But he didn't seem to care at all.

To be honest, it would be great for her to follow the rules-it's a bit like she has a treasure that is priceless, everyone in the world wants it, but she can't use it.

Now Zheng Fa told her, I don't care about your treasure.

But I buy it at a certain price. If you think the price is low and don't want to sell it, that's fine.

It's clear, but it makes people feel at ease.

Thinking about it, I returned home unknowingly.

She fell on the bed and slept well for a long time.

…

Zheng Fa watched Mu Qingyan leave. Of course, he also knew that this person had hidden a lot of things.

But... he didn't care too much.

He was naturally tempted by the secret realm of Tianhe Zun, but he didn't break the rules he had painstakingly established for this.

If Mu Qingyan could really have some practical advice, it would be much easier to convince Xiao Yuying...

Just thinking about it, Xiao Yuying came.

She didn't come alone, and she was accompanied by Senior Sister Zhang.

"Senior Sister?"

Zheng Fa blinked, not understanding how these two people got together...

"Fairy Xiao came to me and studied the communication talisman..."

"Hmm?"

Zheng Fa was quite surprised.

He had paid attention to the communication talisman before, but most of his energy was focused on the "Golden Elixir Project" and he had no time to split himself.

But he didn't forget about it.

Xiao Yuying seemed to have forgotten it, or rather, didn't care. She just mentioned it casually that day, and she didn't understand Zheng Fa's attention to it.

Unexpectedly, Xiao Yuying actually took the initiative to find Senior Sister Zhang to study the communication talisman...

He looked at Fairy Xiao and had a guess in his mind——

Is this because Mrs. Xuanhua got involved?

"Xianzi Xiao and I disassembled and analyzed the communication talisman..." Senior Sister Zhang explained: "According to the theory of the three talismans, the communication talisman is the water element talisman, and the god's name talisman is nothing special, except for the last one. The talismans are ever-changing and seem to correspond to different monks."

Zheng Fa nodded.

"But one of the structures is very special." Senior Sister Zhang drew twice in the air, "If you use topology to analyze this structure, you will find that it is present in every communication talisman."

"I asked Fairy Xiao to sense it. Once I draw this structure, the electromagnetic field in the communication talisman seems to remain stable."

After Zheng Fa listened, he thought about it and somewhat understood what Senior Sister Zhang meant:

"Sister, are you saying that this spiritual circuit can shield the interference of spiritual energy on the electromagnetic field?"

Senior Sister Zhang nodded and explained: "My own analysis, the principle of the communication talisman should be to transmit information through the electromagnetic field - and the runes in it have two functions:"

"Shield the interference of external spiritual energy on electromagnetic signals and avoid changes in the electromagnetic field during the propagation process."

"In addition, the most important function is encoding."

"Encoding?" Zheng Fa suddenly realized, "You mean, there are different talisman structures corresponding to different monks? The process of a monk receiving the communication talisman is equivalent to decoding?"

"Yes, this is what I thought of when I read the book "Coding","

Zheng Fa couldn't help but stood up, held Senior Sister Zhang's arm, and said happily: "Senior Sister Zhang, your name will go down in history in the future!"

"?"

A question mark slowly appeared on Senior Sister Zhang's face.

She didn't understand why Zheng Fa was so excited.

"Maybe you will be remembered as the mother of the Internet by future generations!"

"..."

Senior Sister Zhang curled her lips, seeming to find the nickname unpleasant. Xiao Yuying on the side was more interested and asked with interest: "What about me? Didn't I also take credit for this research?"

Zheng Fa glanced at her and knew that this so-called research required a corresponding understanding of talismans, electromagnetism, informatics and topology. It could even be said that it required an extremely high level.

In the Nine Mountains Realm, only Senior Sister Zhang has this ability.

As for Xiao Yuying, she is probably a sensor called 666...

Facing Xiao Yuying's expectant gaze, Zheng Fa thought for a while and said:

"Maybe the aunt of the Internet...?"

Senior Sister Zhang looked up and suddenly felt that her nickname was quite nice.
