It turned out that Lu You had already made a prototype of the artillery with a tripod base at the tail of the bamboo nozzle, and this kind of artillery also has the advantage that it can be made bigger and longer, so that the machine inside can also be relatively complex, and it can drive the gunpowder to be sprayed farther and higher, but it is still far from the requirements of the war.

In any case, this progress is a breakthrough, because there are already people who understand it, and put forward a new idea, saying that it is possible to change the bamboo tube into an iron tube, and the artillery does not need to be mounted on people's shoulders, but can be directly placed on the ground, which is easy to operate, and there is no need to worry about gunpowder failure or other accidents that will hurt people's lives.

Therefore, the biggest problem now is that the strength of the machine is not enough, and the gunpowder launched cannot fly far, so Li Cong hit Yan Yan with his idea.

Because he had already asked and understood, this tripod was thought up by Lu You, and thinking that this nozzle was also the first to come up with by Lu You, Li Cong set his eyes on Yan Yan.

It's not that Li Cong hasn't taken the school exam Lu You, Lu You has indeed read a lot of books, and he will also make some mechanical things by himself, and the improvement is okay, but the invention and creation seem to be lacking.

But Yan Yan is different, Yan Yan has invented a lot of new things, first cakes, hot pot and other aspects of eating, and then transferred to the map model, and then the planting of yams and cotton, etc., these things were unheard of and unseen before Yan Yan came out, therefore, Li Cong prefers to believe that the idea of this nozzle and tripod is also from Yan Yan, but Yan Yan doesn't want to be famous, so he pushed Lu You out, which can be regarded as paving a way for his husband.

Of course, Li Cong doesn't deny that Lu You's understanding is indeed not bad, and he also has some goods in his stomach, so Yan Yan dialed it a little, and he could quickly understand Yan Yan's hints, but this stupid boy is probably still in the dark, and he doesn't know how much light he borrowed, and he thought that he had made this breakthrough by mistake.

In order not to alarm Yan Yan, Li Cong naturally didn't wake up Lu You, but he was really a little curious about Yan Yan's origin.

But when Li Cong saw Yan Yanyan smiling and accompanying the two old men to recall some of the Yun family's past decades ago, he was a little skeptical of his previous judgment.

If you want to say that she is not the Yan Yan before, she knows everything about the Yan family, and even knows a lot of the Yun family's past, and these things can only be told to her granddaughter by Mrs. Yan.

If you want to say that she is the Yan Yan before, Li Cong also muttered in his heart, a person's personality will definitely change once he dies, he doesn't doubt this, and he doesn't doubt Yan Yan's talent in those poems, piano, chess, calligraphy and painting.

But since Yan Yan planted the cotton, bitter gourd, and carrots, he didn't quite believe that this woman was still the boudoir woman who didn't go out of the door before, because these three things were not available in the Great Zhou, and they were seeds from the hands of Western missionaries, but Yan Yan didn't know Western dialect at all, and the two missionaries could only speak a few simple Hokkien words, but Yan Yan not only knew the purpose of these things, but also knew how to eat bitter gourd and carrots, which made Li Cong suspicious.

He knew that it was Lu You who accompanied Yan Yan to meet the Western missionary, and he also knew that Yan Yan communicated with Westerners by drawing and analyzing, but can painting and analogy tell how these things are planted and eaten?

Li Cong didn't believe it.

But if Yan Yan has changed people, Li Cong doesn't believe it, because this can't explain Yan Yan's closeness to them, in the past two years of contact with Yan Yan, he seems to have regained the admiration that Yan Yan had for him before Mrs. Yan died, and this feeling can't deceive people.

Therefore, the best explanation is that Yan Yan had some adventures, most of which were related to her resurrection from the dead, but why didn't this girl refuse to teach him?

Wasn't his grace to her great enough?

Yan Yan accidentally found that Li Cong was wandering, but she didn't think that the problem was herself, thinking that he was worried about the war on the front line again, because Yan Yan heard him ask Yan Yu a few words about Lu Ming's injury.

Thinking that it is easy for everyone to get together during the Chinese New Year, especially for the Queen Mother and the Old Man Yun, this kind of opportunity is particularly precious, so Yan Yan smiled at Li Cong: "Uncle Emperor, I just heard the Queen Mother and Uncle and Grandfather talk about the food in southern Fujian for half a day, I am a little tempted, and when the grandfather is finished taking the exam, the emperor's uncle will give us a few months off, let's go to southern Fujian, and bring a little more fruits and seafood from the south to the Queen Mother and Uncle and grandfather, how about it?" Maybe we'll be lucky, and we'll be able to meet some more Westerners who want some other new seeds. ”

It's a pity that at this time, the American continent has not yet been discovered, and the peppers, sweet potatoes, peanuts, corn, etc. that Yan Yan wants are still far away.

Li Cong didn't hear what Yan Yan said before because he was distracted, but heard the last sentence, "Oh, what other seeds do you want?" ”

"Uncle Hui, Uncle Hui, when you ask like this, how do I know what seeds there are, I have to see them before I know, right?" Yan Yan replied, suddenly thinking of something, "Uncle Emperor, did you agree with me to go to southern Fujian?" ”

"To Minnan?" Only then did Li Cong react, "Do you want to go to southern Fujian?" ”

As soon as he asked this, not only did the Queen Mother and Old Man Yun know that Li Cong was distracted, but the others present also felt that something was wrong.

Fortunately, Li Ji reacted quickly, he knew that what Lu You was doing now was very important, so he knew that his father would not let Lu You leave at this time, so he said with a smile: "It's easy for the sixth brother to not be hungry to eat, why is Yan'er's sister greedy again, shouldn't the sixth brother kidnap Yan'er's sister too?" ”

"I don't like to hear what Brother Prince's words say, and now I don't just think about eating, I also follow Yan'er's brother-in-law to do things, and even my father praises me for my growth." Li Sui quit.

"Ah, Sixth Highness, what are you doing with my eldest brother-in-law? What do you do? Yan Bin was curious.

"Stop, it's better to eat on this topic, today for the New Year, only allowed to talk about things related to food, Uncle Emperor, tomorrow we will go to the palace to visit relatives, I don't know what kind of dishes we can arrange? Can I order two dishes a la carte? Yan Yan pulled the topic back again.

"What do you want to eat? But it doesn't hurt to say that. Li Cong still gave Yan Yan this little face.

Yan Yan heard that she hurriedly ordered a chrysanthemum bear's paw and a duck tongue soup, mainly because the ingredients for these two dishes are more troublesome, the former is scarce and troublesome to make, and the latter is a large number, she can't kill hundreds of ducks just to eat a duck tongue soup, right?

The palace is different, there are a lot of palace maids and eunuchs, and it is not difficult to consume hundreds of ducks.
