Li Sui didn't mean anything else to stay as a guest, he just simply thought that Zhou Wan's family was down, and life must have been very hard, but Li Sui knew that Zhou Wan was also a person who paid attention to appetite, so he wanted to keep Zhou Wan at Yan Yan's house to have a good meal, and even wanted to send some silver tickets to Zhou Wan, but unfortunately he decided to leave the palace temporarily, and he didn't decorate his body with silver tickets or other valuable objects, for which he was very regretful.

At the critical time, Lu You pulled Li Sui away, he didn't guess Zhou Wan or Li Sui's thoughts, but he saw Yan Yan's embarrassment and Yan Yan's dislike.

As soon as Lu You and Li Sui left, Yan Yan said directly: "Sister Wan'er, it's not that I don't want to keep you, but I really can't keep you, if today's matter is spread into the palace, I'm afraid that even I will have to eat it, you know... ”

Zhou Wan was not stupid, and quickly understood what Yan Yan meant, because she remembered that Yan Yan had asked her a sentence before, whether she would disregard human ethics or morality in order to achieve a certain purpose, and she denied it at that time.

In fact, she definitely didn't want to take the opportunity to climb up to Li Sui, because she knew her current identity very well, and if she couldn't get it right, she was afraid that her whole family would have to suffer, so she hurriedly interrupted Yan Yan without waiting for Yan Yan to finish speaking, "Sister Yan'er, I understand, I really understand, I'll leave now, don't worry, I won't confide in the Sixth Highness today." ”

After speaking, she didn't wait for Yan Yan to answer, hurriedly curtsy to Yan Yan, and went out with her little girl, Yan Yan ordered Qingmiao to send her into the carriage and out of the gate before coming back.

Besides, after Yan Yan sent Zhou Wan away, he took the cross bow and crossbow in his hand and entered the study, Lu You and Li Sui were lying on a pile of drawings, this is a set of maze mechanism diagrams drawn by Yan Yan for Lu You, which Lu You found from the book, because the font is too small and it takes a lot of effort to look at, he asked Yan Yan to help him redraw a set, which is enlarged a lot.

This set of maze mechanism diagram is designed according to the direction of the gossip, Lu You in order to try the effect, is going to try it in front of the gate of Mingzhuang, at the same time, he also plans to re-strengthen the fence in the Zhuangzi, without wall bricks, still with a fence with thorns, but will add some mechanisms in the thorns, what is it Yan Yan did not ask.

And the reason why Lu You thought of these was inspired by Yan Yan asking him that day how he would break the situation if the capital was besieged, the capital was besieged, and the first thing to bear the brunt of it must be grain and grass, so these Zhuangzi outside the city would definitely become the first place for these foreign enemies to loot.

He can't control anything else, he plans to strengthen the periphery of the Zhuangzi under Yan Yan's name.

Yan Yan knew that his thoughts did not stop him, on the contrary, Lu You's move was exactly what she wanted, she was afraid that the tragedy of the Northern Song Dynasty would be repeated in this time and space, but now she couldn't let her leave everything in the capital and hide in the south. So, what she can do is prevent it from happening.

Seeing Yan Yan come in, Lu You and Li Sui raised their heads almost at the same time, and seeing that Yan Yan was alone, a trace of disappointment flashed in Li Sui's eyes.

"Sister Yan'er, Miss Zhou is gone?" Li Sui asked first.

"Yes, she's here to give me a gift, and she has to go somewhere else, otherwise, it won't be easy to get out of the city when it's dark." Yan Yan hinted.

"Out of town? She didn't live in the city? Li Sui was obviously a little surprised by this answer.

Yan Yan also knew that Li Sui didn't know Zhou Wan's recent situation, after thinking about it, she briefly explained a few words, but omitted Zhou Wan to follow her to learn to take care of the farm, only said that she and her family lived in a town outside the city, Zhou Wan's father opened a private school, Zhou Wan's two younger brothers were studying, Zhou Wan and her mother did some needlework to supplement the family, and the family also had a little bit of land, although the life was not very rich, but food and clothing could still be guaranteed.

"If I'm not mistaken, she's going to be a good year, right?" Li Sui asked suddenly.

Yan Yan heard the meaning of Li Sui's words, but she was really difficult to answer this question, so she took a look and said: "It's true, the birthday in April was not held in the city, and I only found out later, so I made up a congratulatory gift for her." ”

It is said that only a few relatives of the Zhu family and the Zhu family were invited, and there were not many elders to go, either to send the younger generations or send the next person to send a congratulatory gift, and Yan Yan also heard about it after someone went to her village to see the survival of cotton transplanting, and at this time it has been three days since Zhou Wan's New Year's ceremony.

Rao is like this, Yan Yan still made up a congratulatory gift for her, she wanted to take the opportunity to help her.

And Li Sui heard that it was not done in the city, and he guessed some reasons, as far as the current situation of the Zhou family is concerned, even if it is done in the city, the previous female dependents will not be able to participate, but it is even more embarrassing.

Lu You was a little impatient when she saw Li Sui asking about Zhou Wan's situation vigorously, "Do you still want to watch this?" ”

"Look, look, where did you go?" Li Sui hurriedly put his eyes back on the drawings.

Yan Yan saw that the two of them had something to do, so he hurriedly retreated.

After about half an hour, the two of them came out of the study, and Yan Yan was sitting in the hall with the crossbow and crossbow to study.

"How, Sister Yan'er, is my brother-in-law really smart?" Li Sui jumped in front of Yan Yan in a few steps.

"It's really small, it's hard for the two of you to come up with it, the most important thing is practical." Yan Yan praised.

"This has nothing to do with me, my brother-in-law came up with it, by the way, Sister Yan'er must not know yet, there is an old man in the Ministry of Works, he saw this thing made by his brother-in-law, and said that he would accept his brother-in-law as an apprentice." Li Sui said with a big grin.

"Oh, and that?" Yan Yan looked at Lu You.

Lu You smiled faintly, "It's Master Yang, we studied the trebuchet together, and I learned a lot from him." ”

Yan Yan understood as soon as he heard it, that Master Yang had been committed to the study of instruments for decades, although the trebuchet had little effect, but there must be something outstanding in other places, otherwise the emperor would not have arranged him to Lu You's side.

If nothing else, his experience is not comparable to ordinary people, and the only thing he lacks should be theoretical knowledge.

And Lu You's appearance just made up for him, the trebuchet model is the best example, and now there is this crossbow and crossbow, and in time, the two will definitely be able to cooperate to create other new equipment.

Therefore, Yan Yan's heart moved when she heard this, she thought of artillery, but she really didn't know how to guide their research ideas here.

Lu You saw that his wife was stunned, thinking that she was tired, and he knew that his wife had a habit of taking a lunch break, so before Li Sui said that he wanted to stay for dinner, Lu You took him back to the Ministry of Engineering, where there were still many things waiting for him.
