Lu You was relieved when he heard that he was not asked to go to the front line but to help improve the equipment, but he still had no confidence in himself, but he couldn't bear to let Yan Yan down, so his eyes looked at Yan Yan very contradictory.

"Husband, remember what I once said to you, just do your best in everything, it's a good thing to succeed, it doesn't matter if you don't succeed, at least we have worked hard, just like I asked you to do the scientific expedition before." Yan Yan guessed what the other party was thinking and said comfortingly.

"Okay, I listen to the lady, as long as the lady is happy, I am willing to try my best no matter what." Lu You let go of the knot in his heart and took Yan Yan's hand.

Yan Yan remembered another thing because of this, if Lu You wanted to help study the improvement of equipment with those craftsmen, then he would definitely not have time to go to the academy to study, what about next year's scientific examination?

"In this way, I can study at home by myself, and if I don't understand something, I can ask Mr. together, or the hard lady will help me explain it."

Lu You has been in the academy for more than a year, and he is still very confident in himself, because he has read most of the homework assigned by his husband, and he is very familiar with it, and even the annotations can basically be memorized, so he doesn't have to worry about the Ming Sutra.

As for his weak policy, Mr. has already begun to deliberately train him, and Yan Yan will also ask him some views on political affairs and current affairs, intentionally or unintentionally, especially the advice directed by Yan Yan, which can always be praised by Mr.

Therefore, he felt that staying with his wife would also be effective, but he needed to go to the academy every once in a while, ask his husband to correct and explain the strategies he had accumulated, and then ask him to give him a few policy questions.

As for the other six arts, he just stayed at home to practice, there are a few big rivers in riding and archery, Yan Yan in piano and chess and mathematics, and he has already achieved a small success in calligraphy, and there is one ceremony left, which he has heard and witnessed with his husband since he was a child, and it is not much worse.

Yan Yan originally intended to send him to Taixue, but when he saw that Lu You didn't have this idea at all, he had to give up, thinking that it would not be too late to wait for him to get the qualification to show talent.

After the two discussed, Yan Yan called Qingyu and Dahe, instructed them carefully, and ordered the two to pretend to be ordinary small merchants to go to Suizhou to find Yan Peng's whereabouts, and then inquire about the military situation or something.

As for the road guide, Yan Yan ordered Dahe to take her post to the prince and ask the prince to find someone to write him a fake road guide, saying that he was going back to visit his seriously ill relatives and friends.

As for Lu You, Yan Yan gave the emperor a letter of repair, recommended him to the Ministry of Industry, and worked with those skilled craftsmen, but because Lu You's personality was more special, Yan Yan noted a little bit and assigned two people to him, and at the same time, Yan Yan also gave Zhou Haisheng to Lu You, because Zhou Haisheng himself knows bricklayers, masons, and simple carpentry, and the most important point is that Zhou Haisheng was once the prince's person, and with him, outsiders can't bully Lu You.

Li Cong obviously didn't expect Yan Yan to give him such a big surprise, but at first he didn't think that Lu You had the ability to do it, but thought that Yan Yan wanted to borrow Lu You's hand to make her own ideas, in other words, Yan Yan didn't want to be famous.

Therefore, Li Cong agreed with a stroke of his pen, and soon sent someone to pick up Lu You.

Since then, Lu You has lived an 8-to-5 working life similar to that of later generations, and the Ministry of Industry has set up several large rooms for these craftsmen, divided into several groups, each group is equipped with two older masters, who can read drawings, and have also worked trebuchets before, in addition to four or five skilled workers who do specific things.

Partnering with Lu You is a 60-year-old master, surnamed Yang, Master Yang has been working in the Ministry of Engineering for so many years, trebuchets, even bows, crossbows, etc., and it is not that he has not considered improvement, but unfortunately it has not achieved much effect.

Yan Yan herself has also seen the drawings of the trebuchet, and she can still understand the general principle, but it is definitely not possible to let her do it, but she gave Lu You a few suggestions, one is to see if the number of point pulleys can be increased appropriately, because through the effect of the pulley, not only can the weight of the throw be increased, but the most important thing is to save effort, and at the same time, it can also reduce the weight and volume of the point trebuchet; the second is to see if it can be made into a trebuchet that can be disassembled at any time; If it can't be disassembled at any time, it is best to add a few wheels underneath it for easy transportation.

It's just that she doesn't understand how to do it, and it needs to be tested in practice, so her proposal to Lu You is to make a small model first, saving time and effort.

To Yan Yan's amazement, Lu You's comprehension ability is very strong, he combined the trebuchet mentioned in the books he had read such as "Mozi" and "Guiguzi", and according to Master Yang's years of experience, a month later, they really developed a relatively small and practical trebuchet that can be disassembled at any time.

This kind of trebuchet does not need more than 200 people, the model can be operated by two people, and it can throw a stone of about ten catties out of five or six zhang away, and it can also be two zhang high, this number greatly encouraged Lu You.

At the same time, there was also news from Yan Peng's side, Yan Peng was really injured in the battle of Suizhou and fell into a coma, the situation was particularly chaotic at that time, the Xixia people thought he was dead, and the soldiers around Yan Peng also thought he was dead, thinking that he would bring his body back no matter what, so he ordered two guards to carry him out on his back, and the others broke off.

In the end, all those who remained behind were killed, but the Western Xia side also lost a second-rank general and dozens of soldiers.

And after the two guards escaped from the battlefield with Yan Peng, they learned that Yan Peng was not dead, but Suizhou had already fallen into the hands of the Western Xia people, so they could only take Yan Peng to hide in the mountains and find a hunter to recuperate, so as to delay the contact with the outside world.

And Yan Peng was also seriously injured at the time, and he woke up after being in a coma for more than ten days, but his body still couldn't move, and the high fever did not go away, and the two guards did not dare to take him on the road in this situation.

After Yan Peng's injuries stabilized, the three of them made a detour back to Da Zhou's side, but they happened to run into someone sent by the emperor to find them.

Yan Peng knew that he would not be able to return to Beijing under such circumstances, so he took the initiative to ask to go to Gyeongju, which was guarded by Yan Ai, and he wanted to guard Gyeongju with Yan Ai, waiting for an opportunity to see if there was still a chance to recapture the three cities.

As soon as Yan Yan heard that Yan Peng and Yan Ai had met, he was not so worried, Yan Ai had been stationed in Gyeongju for many years, and it was difficult to say anything else, but in terms of actual combat experience on the battlefield and the ability to arrange troops, he was definitely stronger than Yan Peng.

Because Yan Peng had never been on the battlefield before, he only sat in the position of the prince of Dingnan Hou after the death of Yan Yan's father, and it was obviously too late to re-cultivate him at that time.
