I studied abroad in modern times

"From these three external alchemy methods, if you want to practice external alchemy, the most important thing is the alchemy furnace, and the second most important thing is the technique."

Comparing the "External Alchemy" sent by Mu Qingyan and the two external alchemy methods given by Xiao Yuying, Zheng Fa easily came to the conclusion.

Beside him, there were Senior Sister Zhang and others.

Three jade tubes circulated in the hands of several people. After reading them, everyone nodded.

"This idea is easy to understand. The structure of the alchemy furnace corresponds to the cultivator's body, and the alchemy technique corresponds to the corresponding alchemy method." Senior Sister Zhang spoke first, and she frowned and added, "But in this way, the "Golden Alchemy Project" will be troublesome."

"Yes." Uncle Pang also nodded and said, "We can simplify the method, and the structure of the alchemy furnace is really not our Jiushan Sect's strong point."

This is a manifestation of the Jiushan Sect's shallow foundation.

He didn't say anything, thinking in his heart whether modern society can help-it seems difficult.

"The most important thing about the Dan Ding of the external elixir is the so-called three gates and nine orifices, which simulate the human body with the Dan Ding..." Senior Sister Zhang added, "The differences in these Dan Dings should actually correspond to the differences in the cultivators who practice these exercises."

Zheng Fa nodded lightly, this is very obvious.

The problem is - how exactly do they correspond.

This is complicated.

Seeing Zheng Fa's distress, Senior Sister Zhang suddenly smiled and said, "I can try these three exercises."

Hmm?

Zheng Fa was stunned, and suddenly remembered - in terms of simulation, Senior Sister Zhang's Yuanling Dao body is the ancestor!

…

In Senior Sister Zhang's yard.

There are only Zheng Fa, Senior Sister Yuan and Senior Sister Zhang.

"The "Golden Dan Project" project team is ready to cast the Dan Ding." Zheng Fa said to Senior Sister Zhang, "After we collect your body data here, we will compare it with the corresponding Dan Ding, and we will probably be able to see some of the secrets of the Dan Ding."

To be honest, if it weren't for Senior Sister Zhang, this matter would not be so simple - there would be no one practicing those three exercises in the Nine Mountains Realm.

Senior Sister Zhang nodded, crossed her legs on the mat, and her body gradually became transparent.

Unlike before, there was a small three-head-body version of Senior Sister Zhang in her body.

The little guy wore a five-color headband, had a round face, and had his chubby legs crossed, as if meditating.

Senior Sister Yuan was confused, and there were two words in her eyes - I want to pinch!

Not to mention her, Zheng Fa was attracted by this little guy. Senior Sister Zhang was usually very cold, and now seeing her so cute, it was really a bit of a contrast.

The two stared at each other for a long time, and saw a trace of shame on the little guy's face.

"Ahem!" Zheng Fa didn't dare to do anything stupid again, turned his eyes and said, "Senior Sister Zhang, try the "Hanhai Zhenjing" first."

Hearing this, the spiritual power in Senior Sister Zhang's body kept dispersing and gathering, and after a while, it began to operate according to the route in the "Hanhai Zhenjing".

As the spiritual power passed through the meridians, all the meridians and acupoints in Sister Zhang's body began to change subtly.

Zheng Fa recorded these changes while sighing in his heart:

Senior Sister Zhang's Yuanling Dao Body is really superb in controlling spiritual power. She can do whatever posture she wants.

What about Xiao Yuying's Yuanci Dao Body? Don't try to touch me!

...

Xiao Yuying walked into the classroom unhappily. Today was her first class as an archaeology professor.

Zheng Fa sat in his seat and understood her unwilling expression in his heart -

A rich man who picked up money when he went out suddenly became a working dog... If it were you, you wouldn't be able to laugh.

Xiao Yuying stood on the podium and saw Zheng Fa first. She glared at Zheng Fa lightly, as if she thought he was an eyesore.

When she saw the classroom full of students, she was a little dazed again. Obviously, she didn't expect there would be so many people.

Zheng Fa came to listen to the class mainly because he was a little interested in Xuanwei tomb-robbing...ah, archaeology, and on the other hand, he also wanted to see how good Xiao Yuying's teaching skills were.

As for other students, first of all, of course, they were more concerned about this subject, after all, the Xuanwei world was very enthusiastic about things like secret realms.

Secondly, Xiao Yuying was famous.

After all, Xiao Yuying had seen big scenes, so she was stunned for a while, and then became expressionless again, and said:

"Your leader asked me to talk to you about "archaeology". To be honest, I don't know what archaeology is..."

When she spoke, her tone was flat and there was no emotion at all. She was just a ruthless teaching machine.

"I can only tell you about some secret realms I encountered and my previous experiences..."

Xiao Yuying obviously didn't make a lesson plan, and she just talked about whatever she wanted to say.

"Fifteen years ago, I encountered a cave left by an ancestor in Tianhai County."

"Of course, I didn't find it. When the cave was born, many cultivators went there... It's not important."

Xiao Yuying flicked her finger, and her spiritual power drew something in the air that looked like a rune.

"At that time, when I saw this rune, I knew that this cave probably belonged to our era, and it was about 100,000 years ago."

The disciples in the audience were inevitably a little confused.

Seeing this, Xiao Yuying explained: "This rune looked like this 150,000 years ago."

She drew a more complicated pattern in the air.

"Now it's a little simpler."

Xiao Yuying drew another rune.

After all, Jiushan Sect was founded by the rune method, and it suddenly became clear when she heard her say that.

"What are the benefits of judging the age of this cave?" Xiao Yuying explained, "The style of secret restrictions in each era is actually different."

"For example, that cave adopts one of the three most popular restrictions 100,000 years ago."

"If you realize this, you will be able to break the restriction and enter the cave faster than others."

Zheng Fa nodded secretly.

Although Xiao Yuying seemed reluctant, she was not shy when teaching.

The problem is that she really has something in her stomach!

"Not only that, the layout style of caves in each era is also different."

Xiao Yuying added, "For example, the cave in Tianhai County, as soon as I entered, I found that it was the most popular layout among alchemists 100,000 years ago... With this understanding, you can quickly and accurately find out the possible location of the treasure hidden by the owner of the cave, and you can also roughly guess the means left by the other party."

"..."

While Xiao Yuying was talking about her own experience, she casually talked about some knowledge points that others didn't know.

Listening, Mu Qingyan's eyes lit up in the audience!

She compared what Xiao Yuying said with the memories in her mind - and she found that many caves seemed so simple to find treasures with Xiao Yuying's ideas!

...

Although Xiao Yuying did not make any preparations for her lectures, her rich experience and profound knowledge in the field of archaeology far exceeded others.

It's just that no one had explored her potential in this area before - or in other words, no one could tempt her to give lectures.

In her lectures, two hours seemed like a flash.

When she said the word "get out of class is over", the students in the audience burst into great enthusiasm:

"Fairy Xiao, give one more class!"

"Teacher, we still want to listen!"

"..."

Xiao Yuying was really stunned.

Zheng Fa looked at her slightly helpless expression and couldn't help laughing - this person is not very popular wherever she goes, and probably has never received such a warm welcome.

But to be honest, these students are really sincere.

Who doesn't like to listen to tomb robbing!

What's more, tomb robbing is a way to get rich, but it's illegal.

Tomb robbing in the Xuanwei Realm...

That's a bright road!

...

When I saw Xiao Yuying again, she had less resentment on her face.

After all, she was a Yuanying Zhenren. Although she was not fooled by a group of students, she was very popular in the Jiushan Realm, so she felt much more comfortable.

In the end, she also found a little happiness in being a teacher.

She came to Zheng Fa to take a tutorial on "Electromagnetism".

Her foundation was not bad. In the Jiushan Realm, her understanding of electromagnetism was probably on par with that of the old man.

After Zheng Fa taught her a few times, he found that Xiao Yuying was definitely a genius in this area - her advantage was obvious, and she had an intuitive feeling for many electromagnetic phenomena!

To be honest, this kind of talent is a killer for abstract theories.

What Xiao Yuying lacked was a mathematical foundation, so when Zheng Fa talked to her now, he almost only talked about qualitative and not quantitative.

"Electromagnetic waves...frequency, amplitude?" Xiao Yuying listened and suddenly said, "I have read about this in those books before, but I don't quite understand it. According to the books, the light we see is also an electromagnetic wave?"

"Yes. The Maxwell equations you heard before can be used to deduce this...well, not necessarily."

Zheng Fa suddenly reacted. The speed of light in the Xuanwei world...it's really hard to say.

"I understand a little bit now..."

"Hmm?"

What do you understand?

"It seems that the communication talisman before had the kind of fluctuations you said...I thought I was wrong."

"..."

Zheng Fa opened his mouth and looked at Xiao Yuying.

The communication talisman has always been a small bug in his mind. The main problem is - what is the principle of this thing, how can it identify cultivators, and what is the carrier of information...

According to the explanation of traditional talismans, this thing identifies cultivators by relying on the different souls and spiritual powers of the cultivators.

As for the carrier...spiritual power is omnipotent!

But what Xiao Yuying meant by this statement is...

The communication talisman is similar to radio?

People didn't understand it before, probably because they didn't have such strong electromagnetic perception ability as Xiao Yuying.

Thinking of this, he couldn't help but respect Xiao Yuying's Yuan magnetic body - you know, if this is true, this matter is of great significance to the Nine Mountains.

The communication talisman, if Xiao Yuying is not wrong, this kind of spiritual talisman can transmit various electromagnetic wave signals remotely...

Among them, Zheng Fa is most interested in how this thing shields the interference of spiritual energy on electromagnetic signals!

If this can be figured out...

Then the energy generated by the nuclear reaction in the Golden Elixir Project... will be useful.

Even, he can think about the Internet age!

He looked at Xiao Yuying and couldn't help laughing.

This kind of talent...

It's too late!
