I studied abroad in modern times

"I can't see anything from this."

Looking at the Xuan Lei Stone under the microscopic array, Uncle Pang frowned.

Not surprising.

The microscopic array is not more sophisticated than the "Dongxu Spiritual Eye", so the three of them could not discover anything new just by relying on the microscopic array.

Zheng Fa didn't speak, but his eyes flashed with silver light - he had known the limitations of the microscopic array, and this attempt was just to see if the microscopic array could be used in conjunction with the "Dongxu Spiritual Eye".

The previous Xuan Lei Stone changed again, showing another scene.

He seemed to see a small universe, dotted with stars and purple and chaotic clouds.

it works!

Zheng Fa felt happy, knowing that the "Dongxu Spiritual Eye" and the microscopic array were indeed complementary to each other.

In fact, he was not sure before, because the limit of optical microscopes does not come from the material, but from the characteristics of light - to put it simply, light will be diffracted when it encounters extremely small-scale matter.

In other words, if the principle of the Dongxu Spiritual Eye is consistent with that of an optical microscope, it cannot break through this limitation.

Now it seems that "Dongxu Lingyan" is not like this.

Looking at the clusters of nebulae in the "void", Zheng Fa couldn't help but smile.

"Um?"

Seeing him like this, Senior Sister Zhang and Uncle Pang looked at each other, and also used their spiritual eyes to look at the Xuan Lei Stone in front of them.

"this……"

Uncle Pang's face was a little dull.

"Uncle Master, have you never seen this kind of scene?"

Zheng Fa asked curiously.

There are countless powerful beings in the Xuanwei world. Zheng Fa is very suspicious that this microscopic world is not a secret to them.

Uncle Pang shook his head and sighed: "I have limited cultivation, so I have never seen it before... What on earth is this?"

Zheng Fa also shook his head.

If he were in modern times, he might guess it was molecules or something, but it was different in the Xuan Lei Stone - the misty place in the clouds was actually rich spiritual energy!

Zheng Fa's heart moved and he waved outside.

There was a pile of stones piled outside the house, which the disciples used to repair the house during this period.

A piece of white stone flew into Zheng Fa's hands and was placed under the microscopic circle. After comparing it with the microscopic scene in the Xuan Lei Stone, the conclusion was very clear——

"The difference between spiritual materials and non-spiritual materials is whether there is spiritual energy in this 'cloud'? And is this spiritual energy fixed?"

Uncle Pang frowned.

Zheng Fa nodded, with a look of surprise and confusion on his face.

It is normal for spiritual materials to contain spiritual energy, but this observation made Zheng Fa understand one thing - there seems to be a so-called spiritual energy molecule? Or aura atoms?

Master Pang has a word he uses very well - fixed.

The reason why spiritual energy is called Qi is that it changes constantly.

But the spiritual energy in this cloud is very stable and has no intention of flowing. What makes Zheng Fa curious is what makes the spiritual energy gather in this cloud and stop escaping.

It's just that the effects of the microscopic array and "Dongxu Spiritual Eye" cannot be 100% superimposed.

He wanted to see the details in the "cloud" clearly, but he was unable to do so.

Zheng Fa tried to study the previously captured copper coffin and the natal flying sword of the Blood River Ancestor - both of them also had similar spiritual energy cloud structures.

It's just that the arrangement is more regular and denser.

"The size of these three types of clouds and the amount of spiritual energy they contain are also very different." Zheng Fa concluded, "But I think there are some similarities in the copper coffin and the flying sword."

Both Master Pang and Uncle Pang nodded.

"There is less spiritual energy in the clouds in the copper coffin, and more in the flying sword." Senior Sister Zhang said, "But the two vaguely seem to come from the same source."

"Both of them are members of the Great Freedom Demon Sect, so it's not surprising that they are similar..." Uncle Pang frowned, "It's a pity that we can't see the details."

"Now there is a problem..."

Zheng Fa thought for a while and suddenly said.

Uncle Pang twitched the corner of his mouth, but then he pricked up his ears and listened.

"Aren't there endless types of spiritual energy clouds..."

"What difference does it make?"

Uncle Pang was a little puzzled.

Zheng Fa shook his head.

Of course Uncle Pang and the others couldn't understand this difference, but Zheng Fa had an idea that he was not sure about -

If the types of this kind of cloud are limited, then he thinks this thing is biased towards the atomic level, because the atoms in the material world are limited.

If it is infinite...then it will naturally favor molecules.

"This is quite simple." Senior Sister Zhang said, "There are a lot of spiritual materials in the Nine Mountains Realm. If we study more, we will know whether they are unlimited."

Zheng Fa nodded.

Uncle Pang laughed at this time and said excitedly: "Leave this matter to me!"

"Um?"

Uncle Pang looked at the microscopic array in front of him and said with a cheerful tone: "This microscopic array can also be regarded as a secret method of my "Dongxu Spiritual Eye"..."

"It's so simple."

"When I study it thoroughly, my "Dongxu Spiritual Eye" will probably be improved to a higher level."

"Then I'll leave this matter to my uncle."

Zheng Fa was also a little happy in his heart. Master Pang was the microscope in his mind. It would be better if he could evolve on his own.

Uncle Pang was still muttering excitedly:

"I want to see not only the spiritual materials, but also the magic weapons..."

"I want to see those spiritual plants in the medicine garden too!"

"You are busy with your business. Your master urges you to hold the headmaster ceremony every day... and you keep putting it off."

"I'm waiting for Yan Wushuang and the others, they're almost here."

The master has wanted to pass on the throne to him for some time, but the headmaster ceremony is not that simple.

Although the Jiushan Sect is now in a remote area, this matter also needs to invite some outsiders to watch the ceremony - mainly to inform outsiders, and also to let everyone notarize, telling everyone that the leader of the Jiushan Sect in the future is surnamed Zheng.

Don't find the wrong person.

Zheng Fa doesn't need to worry about the guests invited by the headmaster.

But Zheng Fa also invited a few people himself, just a few people.

One is Yan Wushuang, and he wants to do some business with the other party in the future.

One is Xiao Yuying, who is also helpful to the Jiushan Sect, so it is reasonable to invite her.

For the rest, Zheng Fa sent another letter to the Seventh Young Master, but the Seventh Young Master didn't reply before, and he didn't know if he could receive it this time.

In addition to these three, there are no others.

It's not that Zheng Fa is aloof. First, he is not good at dealing with people. Second, the headmaster ceremony is held in Jiushan Realm. Outsiders entering Jiushan Realm can be said to be in Zheng Fa's hands. Apart from these few people, Zheng Fa also feels that others are unwilling to take the risk.

...

When Yan Wushuang received the letter, Han Lao, the Sword Immortal of the Setting Sun, was standing beside him, but the two true disciples of Hao Rishan and Tai Shang Dao were gone.

"What? Did your father send you a message again?"

"No, it was sent by Brother Zheng." Yan Wushuang received the communication talisman and looked at it. He couldn't hide his surprise on his face and shouted: "Brother Zheng is going to be the headmaster?"

"Huh?"

Old Han was also stunned.

He thought for a moment and said, "Could it be that Zheng Fa has become a golden elixir?"

When he said this, he remembered the aura on the communication talisman just now, and shook his head to deny it: "No, although this soul is extremely powerful and not inferior to a golden elixir, it is no different from before."

Yan Wushuang nodded after hearing this, and the two looked at each other and felt a little incredible.

"The head of the Jiushan Sect, Yuan, is really free and easy... Zheng Fa is only at the foundation building stage, but he dared to let him be the head."

"This is not incomprehensible. After all, the Jiushan Realm is now in charge of Zheng Fa... It's just that it's indeed a little faster." Old Han nodded and said, "Did he send a message to ask you to attend the headmaster ceremony?"

Yan Wushuang nodded.

Old Han was not surprised, but just talked about another thing: "Then your father asked you to go back, what do you think."

Yan Wushuang's eyes were a little confused.

"He said that this place is dangerous now, and my two companions have also been called back."

The two hid outside a small mortal city.

There used to be a small market under the city wall, but no one came to visit at this time.

Looking out from the market, there are barren farmlands. It should be harvest season, but there are neither farmers nor crops in the fields.

Only clumps of weeds swaying in the wind.

"The Great Freedom Demon Sect..." Han Lao whispered, "It's really hard to be in the secret realm."

Yan Wushuang looked back and saw one or two disciples of the Great Freedom Demon Sect leaning against the city gate and talking and laughing wantonly, with pride written all over their faces.

Looking back into the city.

The shops on the street were all open, but there were no customers. Only people wearing the costumes of the Great Freedom Demon Sect wandered around casually, as if shopping - but judging from the faces of the shopkeepers, they probably didn't dare to ask for money.

It's even hard to say whether they opened the shop voluntarily.

"Why is this Great Freedom Demon Sect... so?"

Seeing this bleak scene and thinking of the various tragic things he heard along the way, Yan Wushuang couldn't help asking.

To be honest, the immortal sects are not very kind to the mortal world, but they also don’t take everything from them. In short, they have a condescending and indifferent attitude.

“Too many people.” Old Han gave an answer that he didn’t expect.

"A lot of people?"

"There is essentially no difference in the attitudes of immortals and demons towards mortals..." Han Lao's words made Yan Wushuang a little stunned, and then he heard Han Lao continue, "But the scale is too different."

"Our disciples of the immortal sect are carefully selected, and most of them have good qualifications. Mundane things are actually not very useful for cultivating immortals, so naturally they don't care much."

"But the magic sect method... uses blood as a bond. The more people are born, the higher the chance of geniuses appearing."

Yan Wushuang suddenly realized: "But there are still so many resources for cultivating immortals, so most people in the demon sect don't actually have the opportunity to practice - the problem is that they are naturally superior."

"That's right." Han Lao smiled, "If you say that the demon sects are all born evil, I don't think so. Are all the immortals good people?"

Yan Wushuang nodded, knowing that Han Lao has always had a prejudice against the immortal sect - but on the other hand, he is also right.

"But the Demon Sect is indeed more ruthless than the Immortal Sect, and is more ruthless to the mortals. Among them, in addition to some of their skills that require mass killing, in my opinion, this natural size difference is the reason."

"Look at the Great Freedom Demon Sect, there are hundreds of millions of people in the secret realm. After coming out, everyone is the best of the best - how can they afford it without scraping the ground three feet?"

Yan Wushuang fell into deep thought, and when he looked at the various scenes in front of him, he actually had some insights.

"So you have to understand that the Demon Sect is naturally despised by people, but it is not that simple to become the leader of a force. Good and evil are not enough to describe a force."

"I still say that there is no big difference between the Immortal Sect and the Demon Sect."

Yan Wushuang knew that he was deliberately reminding him, and nodded: "Disciple understands."

As the two talked, they hurried towards the Nine Mountain Realm.

Old Han seemed to have some ideas, and kept teaching Yan Wushuang through what he saw on the road.

Seeing the refugees with pale faces.

I saw someone trading dignity for food.

Some people trade their bodies for food.

Someone... exchanged his wife and children for food.

He even saw some things that Yan Wushuang finally couldn't help but take action - which led to him being hunted down by the Great Freedom Demon Cult.

With Mr. Han beside him, he was naturally fine, but there was an inexplicable sadness in his eyes and a sullen look on his face.

"Do you know why your father asked you to go back?"

Seeing him like this, Mr. Han chuckled softly.

Yan Wushuang nodded.

"Is this just the beginning?"

Mr. Han agreed:

"Of course, the Hundred Immortals Alliance has shrunk quickly, and the Great Freedom Demon Sect has no trouble. Now its methods are actually quite peaceful."

"But it's impossible for the Immortal Sect and the Demonic Sect to stay out of trouble."

"Once a fight breaks out, these people will probably be even worse off than they are now."

"The Demonic Sect will conquer them, and the Immortal Sect will not be able to do so if they are anxious."

Yan Wushuang didn't say anything, but struck harder along the way.

With Mr. Han protecting him, he was fine, but there were constant disturbances along the way.

It wasn't until they approached the Nine Mountains Realm that they stopped showing off in order not to cause trouble to Zheng Fa.

Walking to a mountain, Yan Wushuang released a talisman that looked like a paper kite, and an arch appeared in front of the two of them.

Uncle Pang came out from the door and said apologetically: "Master Nephew Zheng is currently receiving Master Tongming, so I can only come to entertain you two. Please come in!"

Yan Wushuang and the other two nodded. Master Tongming has become a god, so he is naturally more noble.

The two of them followed Uncle Pang and walked forward into the Heavenly Palace.

As soon as Yan Wushuang came in, she looked around with interest.

Tiangong Jiudao is like a courtyard with three entrances.

The outermost one is centered on Tiangong Island, connected to the medicine garden through Hongqiao, and there is an island that will be used as a market in the future.

This is called the outer three islands by the disciples.

There are also three islands in the middle. Paradise Island is the largest and most central.

It connects Qiuxian Island and Wanxian Island, which are the residential areas of disciples and Yuanying respectively.

This is Zhongsan Island.

Of the three innermost islands, two are the most important to Zheng Fa.

After opening the island, it will be the industrial production area in the future.

The University Island, where classrooms and laboratories are located.

There is also an island that Zheng Fa has not planned yet.

This is the inner three islands.

The main line in the middle is from Tiangong Island to Paradise Island to Daxue Island.

This is the path that Uncle Pang and the other three took.

Yan Wushuang looked around curiously. He had been to Tiangong before, but had never seen these islands. Naturally, they were new.

Uncle Pang naturally introduced us all the way.

"The Tiangong Island just now is basically under the control of the General Affairs Pavilion."

"We have arrived at Paradise Island." Uncle Pang said, "Paradise Island is basically filled with mortals who followed us into the Nine Mountains Realm."

Yan Wushuang and Mr. Han turned to look.

Today's Paradise Island has been initially developed.

Three hundred thousand people form four to five hundred villages, distributed inside and outside the island.

The houses in the village are all newly built. To save convenience and trouble, the appearance of the houses is not much different. They are all small courtyards with white walls and blue tiles, neatly arranged in rows to form courtyards.

The sound of reading could be heard faintly in the village.

"This is……"

"Master Nephew Zheng's idea, what kind of compulsory education is he doing... It is said that all children of school age must study. Those mortals who can follow us are knowledgeable, so naturally we want it."

Mr. Han nodded, his face showing deep thought.

Yan Wushuang didn't think anything, but the anger on his face seemed to have dissipated a lot.

Walking out of the village, many farmers and their wives walked to the fields with hoes on their shoulders.

The new varieties of rice seedlings planted in the fields are already a little green.

After everyone walked for a while, they passed by a village. The children seemed to have finished school. Some of the children were sensible and came to deliver meals to their parents. There was a lot of laughter in the fields.

Yan Wushuang and Mr. Han couldn't help but slow down a little.

What surprised them even more was that there were some monks walking in the fields, surrounded by some farmers, who seemed to be asking questions, but they were not afraid.

The monk didn't have a kind face, but he answered all questions. If he listened carefully, he was actually instructing these farmers to farm.

If a farmer has a problem and asks him to come to his home for guidance, he will think about it for a while and say he will have time in a few days.

"this……"

This scene made Mr. Han stunned.

"This is also what Master Nephew Zheng thinks. When it comes to agricultural guidance offices, if they can make some contribution, everyone would love to work."

Seeing that they were still puzzled, Master Pang smiled again and said: "Actually, we don't understand why - Master Nephew Zheng always likes to say that cultivating immortals is such a shallow thing..."

Both Han and Lao were still confused.

"Master Nephew Zheng also said that the foundation of us immortals is mortals. Mortals worship immortal cultivators, and immortal cultivators have the obligation to help mortals."

"Anyway, these are some unheard-of fallacies... We can't refute them."

Uncle Pang muttered.

Yan Wushuang glanced at Mr. Han, and then looked at the monk in the distance who was not used to being surrounded by people, but was trying his best, and thought of all the scenes he saw outside.

He was silent for a long time.

Until you get to University Island.

On the University Island, Zheng Fa was standing next to the headmaster, Senior Sister Zhang and others, who were receiving Master Tongming.

Master Tongming also brought many people with him.

Most of them were Nascent Soul cultivators, but one of them behaved very strangely. He was not very old, and his cultivation level was not high. He only practiced Qi, but he stood very close to the front.

This man lowered his head, as if he did not dare to raise his head in front of so many powerful people.

But it seemed that he couldn't help it, and kept secretly squinting at Zheng Fa.

"I heard that this disciple of the Qingmu Sect has a deep connection with you..."

Master Tongming pointed towards this person as if he suddenly remembered something.

Zheng Fa looked at the shrunken Seventh Young Master in front of him, and was also surprised and happy - he had been sending letters to the Seventh Young Master, but he did not expect that this person was actually brought to him by Master Tongming.

He couldn't help but smile and said: "This is my old friend. I was worried a while ago."

"Don't worry, Master Zheng. The Qingmu Sect has been migrating a few days ago, so it's normal for communication to be poor."

When the seventh young master heard the words "Master Zheng", he blinked his eyes, and looked at Zheng Fa's expression and became confused again——

Like a dream.
