Even though Feng Duhu looked serious, he actually felt a little uneasy in his heart.

Although it was just a conversation, Feng Duhu was quite shocked.

Du Yu has such insights at a young age, and can be said to be one of the most genius people he has ever seen in his life.

If given time and another chance, the achievements would probably be beyond the reach of ordinary people.

If such outstanding talents slip away from one's fingers, it would be a great regret in life.

What Feng Duhu was afraid of was that if Du Yu didn't want to, or if someone got there first, he couldn't really kill him.

In these days, the king chooses his ministers, and the ministers choose their king - in the same way, the gentleman chooses the best and recruits him as a disciple, and the disciples also want to choose the best and study.

Fortunately, Feng Duhu's reputation is big enough.

There are also dazzling achievements and peerless articles that are guaranteed, coupled with printing technology and improved papermaking technology, to benefit students all over the world.

No matter how talented Du Yu was, he would still be fascinated.

Now that I have the opportunity to join Feng Duhu's sect, how can I still hesitate at all?

Seeing Du Yu kneel down and worship, Feng Duhu secretly breathed a sigh of relief.

"Get up."

"Thank you, sir."

Du Yu stood up, walked forward, took the cup on the table, poured a new cup of tea, and respectfully presented it to Feng Duhu with both hands.

Feng Duhu took it and took a sip.

This is considered a ceremony.

As for the rest, you can make up for it later.

Just when Feng Duhu was mobilizing troops in Hedong and preparing for a counterattack, at Yanmen Fortress in the north of Taiyuan, Shi Zhangyuan, the chief of the Hu Xianbei School Commandant, was standing on the wall of the frontier fortress, looking south in the distance.

He is also waiting for news from Jinyang.

After learning that Sima Yi personally led the army to invade Taiyuan, Zhang Yuan, who stayed behind in Pingcheng, immediately gathered the last few troops in Yanmen County.

At the same time, in the name of protecting the Xianbei captain's mansion, nearly thousands of young Hu people were recruited and ready to support Taiyuan.

It's just that the stability of Pingcheng is of great importance, and Yanmen's troops cannot be easily transferred.

Unless Jinyang sent people to rescue him, Zhang Yuan would not dare to cross Yanmen Fortress and go south without receiving military orders.

Therefore, he could only ask the recruited civilians and barbarians to gather at Yanmen Fortress, while at the same time sending people to Jinyang to inquire about the news.

"Elder brother, there is no news today?"

A man who was also from a martial arts school passed by and said something half regretful and half hopeful.

Zhang Yuan did not look back and reminded:

"Call Chang Shi."

The young man curled his lips and said, "There is no one else here."

Zhang Yuan was one of the first batch of students in Jiangwu Hall, and he was also the most accomplished among the students who came out of Jiangwu Hall.

The most important thing is that he has followed the mountain leader for several years and received personal guidance from the mountain leader.

This is a qualification that everyone would envy.

Therefore, the middle- and low-level young officers who came from the martial arts hall only recognized one senior brother, and that was Zhang Yuan.

Probably because he came into contact with many secrets while working with Feng Duhu, Zhang Yuan has a somewhat deep temperament and most people would not dare to have too much contact with him.

However, he really has nothing to say when it comes to treating underachievers.

Just as the children of Nanxiang are the foundation of the mountain chief, the students trained by the Jiangwu Hall are able to write and read, and dare to fight and fight. Their common beliefs and pursuits make them far more united than others.

In the Han army, it has gradually become a considerable force.

The descendants of Nanxiang, the former Liangzhou Army, and the students of Jiangwu Hall were Feng Duhu's three biggest supporters in the army.

The personnel of these three forces often overlap in identity.

As a loyal follower of the mountain leader and the senior brother of the martial arts hall, Zhang Yuan naturally does not hesitate to support his disciples.

At this time, I saw that although my junior fellow student was speaking openly, it was indeed the truth, so he just reminded me:

"I'm afraid that if you get used to it, you will behave like this in front of outsiders."

"No, don't worry, senior brother, I can still distinguish the seriousness of things."

The junior student shook his head, followed his senior brother's gaze to the south, and sighed:

"I don't know what's going on in Jinyang. They haven't given any news for so long..."

"What is supposed to come will come." Zhang Yuan frowned when he heard this. He was also muttering in his heart, but he couldn't show it, "Why are you anxious."

The junior student chuckled, rubbed his hands, looked left and right, and then replied:

"Nothing but itchy hands and ears."

As he spoke, there was some regret on his face:

"Although we, the Shenji Battalion, took action during Shan's Long March to merge with the state, it is a pity that until now, few people have heard of our name."

"Why are you so anxious? It's just that the time has not come yet. The mountain chief values ​​you so much, why are you afraid that there will be no chance?"

The thunder in Pingcheng in the past few years is far greater than before.

It's just that there have been too many abnormal things in the past few decades.

Droughts and floods are unpredictable, locust plagues occur year after year, and other strange things happen.

One more thunder incident like this will not attract much attention at all.

But Zhang Yuan knew that most of the thunders heard by the people of Yanmen County were not sky thunders, but the Shenji Battalion secretly established by the Zhongdu Protectorate was conducting some kind of experiment.

The predecessor of Shenji Camp was Liangzhou Leishen Camp. After the military was restructured, it came under the jurisdiction of the Central Protectorate and was renamed Shenji Camp.

In the past few years, the mining progress of the mine has been so fast, and the Shenji Camp has played an important role.

"Sima Yi is one of the thieves. Wouldn't it be great if he could make a name for himself?"

The junior is eager to try.

Zhang Yuan glanced at him and poured cold water on him:

"How many qualified Yuandings does the Shenji Battalion have now? Does it have enough firepower?"

As soon as this was mentioned, the junior student fainted:

"not much."

"How much is not more?"

"eight……"

Zhang Yuan glanced at him again: "Don't joke with the lives of the soldiers of the Shenji Camp. If something really happens, the mountain commander will skin you!"

So the junior changed his mind and said, "Five."

Zhang Yuan snorted:

"It took you several years to build five qualified round tripods, but you still want to make yourself famous after Sima Yi?"

The junior sighed:

"There is no way. The iron materials produced in the workshop are rarely suitable."

He scratched his head and said, "As soon as this matter is over, I will go back to Chang'an to see if there is any progress in Mr. Mei's laboratory."

The scientific research team led by Amei and the laboratories below have always been supported by the wealthy Xinghan Association, coupled with the continuous development of the college to cultivate talents.

It can be said that the prototype of the integration of "industry, academia and research" has been formed.

With the support of strong financial resources and the correct leadership of Mr. Feng, there will naturally be no problems with the research direction of the scientific research team.

They decentralize the research results to various places, and each place continuously feeds back problems that arise in practical applications, forming a good cycle.

If you want to build qualified round tripods in large quantities, in addition to smelting iron materials, you also have to see if the iron material formula can be improved, and whether the method of making round tripods can be changed to be more reasonable, etc.

These all need to be tried continuously.

"But five is almost enough. Sima Yi must have never seen artillery..."

"It's Yuanding!"

Zhang Yuan corrected him.

Although the artillery is indeed more vivid, after all, it can correspond to the stone cannon in the army.

But before such an important weapon of the country - this is what the mountain chief said - before it really appears in the world, it is better to call it Yuanding for the time being.

Although others heard the artillery fire, they didn't know what it was.

However, confidentiality rules must still be followed.

"Oh, okay, round tripod, five round tripods fired in a volley, it is impossible to scare Sima Yi to death!"
