At that time, the Queen Mother had already gotten out of the carriage, swept around, did not see Yan Yu, and then looked at the loss on Ma's face when she saw the emperor and the prince, she helped divert the topic of the crown princess, and also asked about the lanterns hanging on the gate and the Chinese knot.

Speaking of which, she can't help this matter, although the emperor is her own son, but she can't take care of him in everything, right?

Besides, the emperor can follow her to the Yun family to visit relatives, and he can give her brother a New Year's greeting with her younger generation, which can be regarded as giving her enough face, and she can still ask her son to go to Yanfu to visit relatives again?

If Mrs. Yan is still here, it's okay to say, but now not only Mrs. Yan is not there, but Yan Peng is not here, what does he have to say to the Ma family when he goes?

But Yan Yan is different, Yan Yan has helped the royal family so much, and has saved the crown prince and the emperor's eldest grandson, plus there is also the relationship between Yan Yan's father, therefore, her son has always regarded Yan Yan as a younger relative.

This can be seen from Yan Yan's marriage, warming the house, and visiting Yan Yan in confinement, so the queen mother is not surprised that the emperor can come to Mingyuan this time, this is not her intention at all, it is her son's own intention.

What could she do?

Fortunately, Ma is also a smart person, and quickly put away the loss on his face, and wholeheartedly accompanied the Queen Mother to talk about the New Year of Mingyuan.

"Yan'er, you made these lanterns with that stupid boy?" Li Cong asked, looking at the two lanterns on the instrument door.

"Back to Uncle Emperor, my husband is not stupid, he can share his worries for Uncle Emperor, do you still call him a stupid boy?" Yan Yan was afraid that Lu You would feel uncomfortable listening to it, so he protested.

Who knew that Li Cong heard this and knocked on Yan Yan's head, "Be content, it's good if I'm willing to call him a stupid boy, but others can't look forward to it." ”

"Thank you for the emperor's love, boy understands." Lu You hurriedly bowed and replied.

"Look, look, people know better than you." After Li Cong finished speaking, he asked Lu You what he was busy with these days.

Lu You glanced at Yan Yan and said with a smile: "Studying, playing the piano, painting, playing, and making Kong Ming lanterns, I want to try it during the Lantern Festival in a few days." ”

The Kong Ming lantern made by Yan Yan and Lu You is different from the Kong Ming lantern in the ordinary sense, they do not want the Kong Ming lantern to rise all the way to the sky, but hope that it can fall down and burn after rising to a certain height, so that if the Kong Ming lantern happens to fall in the city and cause a fire, it will definitely be helpful for the siege.

Of course, this is not something that one or two Kong Ming lanterns can do, a large number of Kong Ming lanterns have to rise and fall together, and they can also be carried out from several directions of the city at the same time.

Before others could come back to their senses, Chen Cha first asked: "Yes, why did I forget the Kong Ming lantern, do you also want to use it in the military?" ”

Lu You smiled slightly when he heard this, "Back to the emperor, we were also inspired by Chen's brother-in-law's paper kite to think of Kong Ming lanterns, and we are planning to try it outside the city in a few days." ”

"Okay, good, strange people often say that heroes have been young since ancient times, if you two can really help me solve this big problem, I will definitely reward you." Li Cong promised with a smile.

He also hoped to find some tricks to quickly recover the three cities, and end the war as soon as possible, otherwise, he was worried that the national strength of the Great Zhou would not be able to support it, whether it was manpower, material resources and financial resources.

Yan Yan also knew this, so he said with a smile: "Uncle Hui, I have good news, my people have basically searched all the mountains near the capital, and collected a lot of potato seeds, I have distributed these seeds, this year it is estimated that the planting of potatoes can have thousands of acres, how can I also harvest millions of catties of potatoes, although it is a drop in the bucket for the entire Windy Country, but it can solve the urgent need, and the situation next year will be different." ”

"This is not good news for me, I have already calculated your harvest this year, it is planned, you have the ability, you can find some unplanned." Li Cong shook his head and said.

"Isn't it, Uncle Emperor, you've been thinking about it for a long time? In case of a ... Yan Yan didn't finish the next words, it was unlucky for the New Year.

No, Li Cong also glared at her, and Yan Yan hurriedly changed into a grinning expression, "Uncle Hui, what I mean is that if the situation is good in the year, it is possible to have a good weather and increase the production by fifty percent." ”

"Fifty percent?" At this time, Li Cong stood still.

Don't look at him as the emperor, but he also knows a little bit about farming, and it is quite good that the average crop can increase production in a good year, but Yan Yan is fifty percent as soon as he speaks, is this possible?

"Back to the emperor, the yield of yams is already high, we were groping to plant it at the beginning, and it should get better slowly." Yan Yan's fifty percent of what he said casually, where would he have much confidence?

Fortunately, at this time, everyone entered the upper room, and the Queen Mother liked it first when she saw a few pots of flowers placed in the room, so the topic was diverged.

Because there is a fireplace in the hall, everyone doesn't have to go to the kang, so they sit down on the circle chairs in the hall, and Qinghe is busy serving tea and snacks.

Yan Tong, Yun Ni, Yun Sheng and the crown princess entered the kang in the east room, taking Li Xi and Lu Jin with their two children.

Yan Zhang, Yan Bin, and the two younger ones pulled the two youngest sons of the Yun family into the study early, in addition to the books, the walls are also full of maps, calligraphy and paintings, in addition, there are ready-made pen, ink, paper and inkstones on the desk, as well as chessboards, piano tables, etc., which are for everyone's entertainment.

Li Ji, Li Sui, Li Zhi, Li Sui and Chen Cha didn't really sit down to drink tea and eat snacks, and quickly entered Yan Yan's study, and Lu You went over to accompany them.

As soon as Li Ji saw the Yaoqin on the piano platform, he thought of one thing, he heard that Lu You moved the mysterious Zhou Lu with a song "A Laugh in the Sea", so he also wanted to ask Lu You to play this song.

"Back to the prince, this song is more suitable for playing after drinking a little wine, and it's a bit inappropriate to play it now." Lu You said with a smile, pointed out the door, and then glanced at Yan Zhang, who was playing chess.

"Oh. In this case, you give us the tune first, and then we go to the back garden after we drink, so don't affect them. Li Ji said.

He also forgot that there were several elders sitting in the hall outside.

When Lu You heard it, he had to find out the lyrics and songs of this song, and in the process of rummaging, he accidentally brought out a few drawings, including artillery, kites, and Kong Ming lanterns, these drawings were drawn by Lu You himself, but they were drawn with charcoal and a ruler under the guidance of Yan Yan, which is somewhat similar to the design drawings of Yan Yan's previous life.
