After sending off Mrs. Lu and the Zhu family, the crown prince and the crown princess sat down and said goodbye, the two of them also came to send a full moon gift this time, and they also came to send a letter to Yan Yan.

According to Li Ji, the people of the Ministry of Industry have used the spring in the structure of the artillery, but it has solved the problem of the firing distance of the artillery, and now there is another problem is how to make the artillery explode directly after coming out of the tube, and there is no need to click the lead again, the main thing is that the process of the lead is more dangerous, and after a long time, I am afraid that the ammunition will not come out or explode in mid-air, and the time is short for fear that it will not explode after landing and let the other party kick away.

Yan Yan didn't understand this question, but in her previous life, she had seen the launch of shells on TV, and they were all filled with ammunition into the barrel by a special person, but she didn't know anything about how the ammunition was made.

"By the way, Brother Prince, I seem to have seen from my husband's letter that they have developed a kind of gunpowder, which is buried directly in the ground, without igniting the fuse, and can explode directly after people or horses step on it, I think this gunpowder bullet can also be used for reference, sorry, I just said it nonsense, it may not work, and I have to ask those masters how to do it."

"I tried, but it didn't work, most of the shots were duds, and I had to knock it hard." Li Ji shook his head and said.

He came this time, he did bring a mission, to see if Yan Yan had any good ideas, no, seeing Yan Yan had no good tricks, Li Ji proposed to leave, not for anything else, but he knew that Yan Yan was still in confinement and couldn't be too tired.

After the crown prince and the princess left, Mrs. Meng suddenly hugged Yan Yan and cried, laughing while crying and wiping her tears, without waiting for Yan Yan to speak, she took the initiative to say: "My granddaughter is really capable, and my grandson-in-law is not bad, now my grandmother is really relieved." ”

Yes, she can finally rest assured, although this granddaughter can't get the love of her parents and in-laws, she has also encountered a lot of calculations, and even almost lost her life, but God finally compensated her, this child has won the love of the most noble masters of the Great Zhou Kingdom with her own intelligence and hard work, with their support, who would dare to bully her?

Of course, the most important thing is that under the wrong circumstances, Yan Yan also married a good husband, and now he has both children and daughters, and he has the ability to create a lot of family business, so he will not have to worry about food and clothing in this life.

A woman, what else can she ask for if she can do this?

Therefore, Mrs. Meng is really content, and she is really happy for Yan Yan.

Who knew that when the two sighed, Ma and Chen Ying came to the door again, but Ma did not suggest that Yan Yan move back to Yan's mansion and move the nest, she just came to give a full moon gift, afraid that Yan Yan would not let in alone, so she had to pull Chen Ying along.

Of course, she did it for outsiders.

Yan Yan naturally knew this, therefore, after hearing Qingxiu's report, she didn't go to see Ma, and ordered Qingglaze to go out to receive her, Qingglaze found a reason, saying that Yan Yan was sleeping, and she received guests in the morning, which would be tiring.

Seeing this, although Ma couldn't stay for a long time, he was embarrassed to go out like this, so he pulled the green glaze and asked some about Yan Yan's daily life, and also asked about Lu Chu's daily life, and also asked about Lu You's whereabouts.

Subsequently, the green glaze handed the gift list sent by Ma to Yan Yan, I don't know if it was to avoid suspicion, Ma did not give Yan Yan any entrance things, but two calligraphy and paintings, a set of high-quality pen, ink, paper and inkstone, sixteen four-season clothes suitable for boys, and a red gold collar, with a longevity lock on the collar.

In short, this congratulatory gift is not thin, and it is slightly more sincere than Zhu's.

It's a pity that no amount of money can buy back the life of the original owner, let alone Yan Yan's heart.

The next afternoon, when Yan Yan was lying on the kang table writing an invitation, the crown princess suddenly came to the door again, saying that the emperor had just received an eight-hundred-mile rush from the Khitan side, and that Zhou Lu had made another request, and that within a month, if the Khitan prince and the two heads of the Zhou family and Yan Yan were not handed over, they would send Lu Duan's body back.

"What? The other party pointed out that he wanted me? Yan Yan was taken aback.

What kind of medicine is sold in Zhou Lu's gourd this week?

What is the origin of this man? Why is it so arrogant? On what basis did he conclude that Da Zhou would obey him?

No wonder Lu You had to go to the battlefield, it turned out that there was really such a day, and this day came so quickly.

No, it should be Lu You's battle to recover Zhending that angered Zhou Lu, so he proposed this quid pro quo to embarrass Da Zhou.

After all, Lu Duan's prestige is too high, and it is impossible for Li Cong to give up on him, which will hurt the hearts of other generals and chill the hearts of these families.

But Zhou Lu's condition is too harsh, in addition to asking for the Khitan prince and the two heads of the family, he actually pointed out that he wanted her, and he didn't need to ask to know that the emperor would definitely be embarrassed, and most of them regretted it, if he knew this, it was better to agree to the other party's conditions as soon as possible, because the other party had not yet mentioned Yan Yan.

"Originally, the emperor wanted to come to you in person to ask for an idea, but he was afraid that the movement would be too big and alarm others, and he was really embarrassed about this matter, but he said that no matter what, he would never hand you over, but it is very difficult to say what the result of this matter will be achieved in the end, so the emperor ordered me to tell you, it is best not to go out these days." The crown princess said.

"Back to the crown princess, I understand, I am tired of the princess's sister-in-law and sister-in-law to tell the emperor, I will not do this full moon banquet." Yan Yan said busily.

Originally, she just planned to celebrate on a small scale, mainly because she received a lot of congratulatory gifts, and she couldn't say that she didn't have it at all, but in this case, where did she still have the heart to think about this?

"It's fine. Your prince and brother and I mean the same thing, for fear that there will be irrelevant people mixed in. It's just that, Sister Yan'er, you have always been smart, but what is there to solve this dilemma? The crown princess asked.

Yan Yan smiled bitterly, she is just an ordinary woman, although she is a little smart, but she is not an omnipotent god after all, what good way can she do?

"Otherwise, let the emperor reply directly to the Khitan, saying that if we see Lu Duan's corpse in a month, we will not only send the corpse of the Khitan prince and the corpse of the two heads of the Zhou family, but also use artillery to open the door of the Khitan." Yan Yan pondered for a while, and finally put forward a suggestion.

This is a game, depending on who has the weight in the other party's heart.

Another point, Yan Yan wanted to test whether this Zhou Lu was her crossing companion, if so, he should know the power of the artillery, right?
