Prince Su guessed correctly at all, Chen Yuan didn't take the initiative to see him, and even avoided him intentionally or unintentionally, indeed because he felt guilty.

Although Prince Su's injury actually had little to do with Chen Yuan, and Chen Yuan also helped him avenge him - none of the people who had killed Prince Su had a good end, but Chen Yuan just felt uneasy.

Chen Yuan's face does have enough thickness to be proud of not being ashamed of making people, but this does not mean that he will ignore his promise.

Talking doesn't count this kind of thing, even with Chen Yuan's shame, he will feel a little embarrassed to see people without face.

Fortunately, as five years have passed, especially after Chen Yuan became Yuanying, things have finally seen a turnaround.

As far as Chen Yuan knew, Prince Su wanted to restore the dantian, and his only hope was to exist in the deepest part of Yunmengze.

And in the depths of Yun Mengze, it seems that there is some kind of inseparable connection with his bizarre crossing.

But if you want to go deep into Yunmengze to find out, you must have two conditions, one of which is indispensable.

The first is radiation protection clothing.

When Chen Yuan was in Chengtian Sect, he also produced a big mushroom in the cottage, but when he planted the mushroom, the radiation damage that Chen Yuan felt was completely different from the depths of Yunmengze.

In the Chengtian Sect, the radiation brought by those uranium stones could be completely resisted as long as the cultivation was slightly higher, and in the depths of Yunmengze, the so-called Mahayana was not immune.

Therefore, a piece of effective protective equipment is indispensable.

Chen Yuan had been preparing for this matter for a long time, and had already ordered it before he assassinated Feng Yiming, and there had always been a team in the treasure selection that was verifying various materials according to his orders, trying to find the one with the strongest radiation protection ability.

This experiment has not stopped even during the period of Chen Yuan's disappearance, and the fat man does not know how many resources he has invested in this in the past five years, and only now can he finally see the light.

The alchemists in the treasure picker discovered that the melt of the cortin stone, after being specially treated and adding a small amount of bright silver, had a strong ability to block radiation.

These refiners had experimented, and the protective clothing made of this hybrid material was extremely powerful in blocking radiation, and they did not suffer any damage even when they penetrated into the range of a hundred miles of Yunmengze Neize, until they encountered a powerful desolate beast.

On the other hand, a powerful thug or bodyguard, Chen Yuan has also already found a candidate—who else in this world can be more powerful than a veteran Mahayana monk who has survived for three thousand years?

Because there was still some preparation to be made, especially the Faraday cage that was isolated from the current needed time to be refined, Chen Yuan set the day to explore Yun Mengze again in three months.

As for the three months, when you see Prince Su, you can still hide.

Fortunately, Chen Yuan can find a good reason for himself, and he is really busy during the period after the start of school.

Various rules and regulations and assessment methods need to be formulated by Chen Yuan, and rewards and punishments can determine people's hearts.

Only Chen Yuan knew exactly how to get such things as syllabuses and lesson plans, and he had to write a copy of them as a template for other teachers.

In addition, there is the course of nature.

Although it is not difficult for a student to recall these basic physical and chemical knowledge points, it still takes a lot of work to compile these knowledge points into teaching materials and pay attention to the logic and connection in them.

In addition, it is necessary to have the right teachers to have the teaching materials.

Although Chen Yuan gathered a group of young teachers who were interested in this so-called natural subject, it would take at least a year to train them.

Prior to this, the nature lessons of these three hundred disciples could only be brought by Chen Yuan, who worked a lot and came to bring them personally.

In the magic class, Chen Yuan taught his disciples the three laws of mechanics, taught them the decomposition and synthesis of force, told them the cause of the explosion, and accompanied the disciples to discuss how to increase the power of the explosion.

In the elixir class, Chen Yuan told the disciples what photosynthesis is, what is apex dominance, what is Mendelian heredity, and he also had to teach the disciples how to determine the approximate furnace temperature according to the color of the flame when refining medicine.

In the Spirit Beast Garden, Chen Yuan explained to the disciples who gathered in a circle what heredity was and what mutation was, and all of this was inseparable from the Heavenly Dao Law of Natural Selection.

As for Chen Yuan's profession, in addition to the three laws of thermodynamics, Chen Yuan also instilled in them the concept of chemical equations, presented them with a microscopic world composed of protons, neutrons and electrons, and encouraged them to find out the differences and connections between various materials after going down, and compile a periodic table of elements unique to the Xiuzhen world.

After three months, these new disciples admired Chen Yuan very much, and in their opinion, this supervisor was simply a pedantic celestial, whether it was the size of the universe or the size of the particles, Supervisor Chen knew everything.

His eyes seemed to be able to see the truth hidden behind all the fog, and the simple words that came out of his mouth could point out the essence of the existence and operation of all things in the world.

In particular, some disciples went to listen to the lessons that those old teachers had taken in the traditional way, and in comparison, they felt that the kind of courses that made people drowsy were not as vivid and interesting as Chen Yuan's side.

This discovery made these disciples completely become Chen Yuan's brainless fans, and they even regarded themselves as Chen Yuan's protégés, and when they looked at the other two hundred disciples, they couldn't help but have some sympathy and some indescribable superiority in their eyes.

However, in order to get the recognition and worship of these new disciples, it was not without a price, in the past three months, Chen Yuan was as busy as a dog, and for the first time hated that his cultivation was too low to distinguish his divine thoughts.

Fortunately, these efforts are still rewarded.

Since most of the two hundred disciples were from families with a cultivation atmosphere, while the three hundred disciples here were basically ordinary people's children, there was a certain gap between the two on the basis of cultivation.

Therefore, in the monthly examination held at the end of the first month, the results between the two can be seen to be significantly different.

However, in just the second month, this gap has been greatly shortened, and it can even be said that it is very small.

What's even more surprising is that in the third monthly exam, not only did the original gap disappear completely, but also the results of these three hundred disciples under Chen Yuan's teaching reform model had steadily surpassed their two hundred peers.

Moreover, whether it is in the firmness of the foundation, the openness of thinking, or the ability to adapt to the war, the stability and innovation ability when refining the medicine and refining weapons, classes one to ten are obviously beyond the Xuanhuang of heaven and earth.

For a while, everyone in the young teachers was excited, the old teachers doubted life, and Ling Daozun made a decision in his heart thoughtfully.
