Zhang Yue stayed in the Imperial Academy for three days, and during this period he taught several guests to the Imperial Academy students.

It mainly talks about the study of things and the integration of knowledge and action.

This is a theory he developed from some theories of Mr. Wang Yangming in later generations, combined with the characteristics of current Gongyang Studies, and mixed with the theories of the "Three-life Theory".

It is just a prototype at present and is far from mature.

However, the students in the audience were fascinated by the students, and even the Imperial College doctors who were attending the audience nodded and gained something.

In recent years, under the guidance of Zhang Yue and Dong Yue, Gongyang School has transformed from a theoretical school to a school of merit that is dominated by world governance.

This integration of knowledge and knowledge and action in the study of things just fills the theoretical gap in the world's achievements.

Therefore, I originally planned to only talk about one day's lecture notes, and I talked about them for three consecutive days.

Zhang Yue took out almost all the things in his stomach, and the lecture notes came to an end.

In addition to the Imperial Academy, Zhang Yue also went to Wuyuan in the past three days.

Unlike the Taixue, Wuyuan was built by him.

Most of the tutorials in Wuyuan were compiled by him.

Especially the book "Cao Dian" which gathers the experience, insights and ideas of veterans such as Zhao Ponu, Sima Xuan, and Xiangru.

This "Cao Dictionary" imitates the structure and format of the later generations "Mosley's Cao Dictionary".

This is the first part of the Han family, and probably the first part in the world, a military work that uses pure vernacular as the carrier.

He doesn't talk about things like strategy or tactics.

It only decomposes the daily training and combat of infantry, cavalry, and crossbowmen in detail.

How do infantry advance? How do crossbowmen turn strings? How do they fire volleys? How do cavalry marching? How do they do combat?

Each program is broken down into detailed steps.

So much so, a Chang'an minister sighed after reading Wu Yuan's "Caodian": "If you read this "Caodian" carefully, you will be no famous general in the world!"

Therefore, this Caodian is the only book in the Wuyuan that is not open to the public.

Others such as war discussions, Sun Tzu's Art of War, and international students from the four barbarians and vassal states have ways to borrow.

Only this book is the only one that international students from the vassal states are excluded.

Even Han people must be students of Wuyuan, or officials with a title of Zuo Shuchang or above/a rank of Qianshishi to apply to the Imperial Academy to borrow.

Therefore, Zhang Yue was treated higher than that of the Imperial Academy in Wuyuan.

Both instructors and students chased him with an almost admiring look.

In Wuyuan, Zhang Yue only did two things.

First, he specially told him to take ten sets of sets from Wuyuan and put them in the public reading room, allowing students to borrow and take notes.

The second is to send the newly improved "Cao Dian" to the Wuyuan as a textbook.

The new "Cao Dian" was written after the Battle of Zhang Yue and Shule.

The main thing is about the use and training methods of the Yingyang Cavalry, which are a brand new method of archers and cavalrymen, and also records the combat characteristics and weaknesses of the Dayuan prisoners who were captured from the mouths of the Kangju prisoners.

As soon as the new "Cao Dicta" was released, the Wuyuan immediately read and studied it hungrily.

Zhang Yue returned to Chang'an with those ten sets of old "Cao Dictionary".

For him, this trip to the Imperial Academy was probably the greatest achievement.

Because, this "Cao Dian" is a brand new military book compiled by him. According to speculation, the ginseng fruit tree in the space should be the best supplement!

With these ten "Causes" films.

Zhang Yue knew that the Eucommia ulmoides he expected to turn into Chinese rubber trees was not ambition, but something that could be achieved overnight.

But reality did not disappoint him.

That night, he entered the space in the secluded attic deep in Yinghou's mansion in Chang'an and fed the ten "Cao Dian" to two already formed ginseng fruit trees.

Sure enough, I got more than ten fruits as hot as flames.

Buried these fruits in the space and planted Eucommia ulmoides tree.

The thing he longed for was finally accomplished.

Because of enough fruits, the cultivation and evolution of the fourth generation of Eucommia ulmoides achieved the effect Zhang Yue wanted almost instantly.

Almost all Eucommia trees, stimulated by the power of the fruit, completed their lives in just one hour, and then left countless Eucommia trees seeds in the open space.

At the cost, not only is the power of the fruit exhausted, but even the space land where these Eucommia ulmoides were originally planted became as hard as iron. Obviously, these lands will no longer be suitable for planting in the short term.

But after Zhang Yue held the seeds picked up from the ground and felt them intently, he knew that the price was worth it.

Under the influence of the power of space, he knew what these seeds would grow after they took root and sprouted.

They are no longer Eucommia trees.

It is a brand new subfamily plant of the Eucommia ulmoideae.

Compared with their ancestors, the glue production capacity of this subfamily has greatly increased!

Conservatively estimated that a mature brand new Eucommia ulmoides tree can produce about two kilograms of glue in one day.

This is close to the rubber tree output in Hainan in later generations.

Moreover, unlike later rubber trees, because they evolved from Eucommia ulmoides, this plant can also be planted in the north.

Of course, there are good sides, and naturally there are disadvantages.

What is known at present are its characteristics such as high requirements for soil fertility, temperature sensitivity, and slow growth.

If there is no space to spawn, it will be cultivated normally outside.

They take at least ten years to grow to the age of gum-producing trees, and their initial output will be relatively low.

It takes five years to gradually increase and reach its peak, and then die after twenty years.

Overall, Zhang Yue was still very satisfied.

However, the matter of choosing a site and planting is quite troublesome.

Because, although these Eucommia ulmoides can also survive in the north.

However, they require sufficient light, sufficient latitude, and sufficient soil fertility.

This kind of place is hard to find.

Therefore, Zhang Yue had no choice but to put this matter aside for the time being and wait for the matter in Chang'an before choosing a site to plant it.

…………………………………………

The next day, before Zhang Yue got up, Tian Shui came to report: "Lord, Zong Zhengqing just sent an envoy to report that the prince returned to the capital today, so please go and greet him!"

"I understand!" Zhang Yue got up immediately and started washing.

The prince's account has not been seen for almost two years.

Since the Crown Prince went south to Luoyang to preside over the river management, Zhang Yue has had little contact with him.

Only Liu Jin would occasionally talk to him about Liu Juzhihe.

At first, Liu Jin talked about the prince's rule over the river, and was excited.

But gradually, his expression began to feel hidden worries, and he was also worried when talking about Luoyang.

Obviously, the father and son have already had a crack and a barrier.

However, this is a normal thing.

When Liu Jin became the grandson and established his own power, it would be impossible for them to go back to the past.

Not to mention the other side, even Zhang Yue and Liu Jin could suppress their subordinate ministers and forcibly create a situation of "father kindness and son filial" with the prince.

Are the ministers under the crown prince willing to agree?

It must be unwilling.

Even if Zhang Yue wants to calm down, he can't resist the constant flirting of others!

Last time, before and after the Battle of Shule, the prince and the ministers jumped up and down, and they were so happy.

Although all these people were put on a list afterwards, the prince announced that he would draw a clear line with them.

However, this crack has already occurred.

Not only the Prince's Office, but also the same on Zhang Yue's side.

Not to mention, there is also the existence of the Emperor's Secret Imperial Execution.

This is simply a huge ridicule!

Now that things have come, don’t say it’s Zhang Yue, even those around him know that there must be a battle between the grandson and the prince!

Moreover, it is very likely that it is a battle where the winner is the king and the loser is the enemy!

Thinking of these things, Zhang Yue sighed and said leisurely: "Prince, actually... he is very good..."
