Liu Zhao gave Qi Fang a chance. Liu Yu could only complete the task this time. It was rare to go home. He went to visit his sister and nephew, and told Liu Jue the truth about Qi Fang's proposal.

Liu Yu's identity has improved so that Liu Jue can raise his head in the Marquis of Dingguo's Mansion, and the people in other yards dare not make too much embarrassment. When Liu Jue heard that Qi Fang came to propose marriage, he was still a little moved on his face, especially when he heard that Qi Fang was competing with his father, Liu Jue sighed and mentioned that Qi Fang could not even catch Liu Zhao's stick back then. What she cared about was whether the matter could be finally facilitated.

"Brother, how sure are you going to be promoted to general?" Liu Jue asked.

"You should be very sure, but it will take a long time to see. If he is promoted to general in his seventies and eighties, can you afford to wait?"

Liu Jue said with a blank smile and said with a glance: "When did you learn to make fun of your sister? Brother... you should help him more."

If you want to help Qi Fang, Liu Jue doesn't need to say that he will do it, because he is afraid that there will be no war in the peaceful times, and it will be difficult to promote a general. After a while, before leaving, Cao Zhan insisted on pulling Liu Yu to play football.

"Uncle is very busy now." Liu Yu said, "How about my uncle's house if he can't get someone to kick you?"

Cao Zhan asked with wide eyes: "Does there be many people in my uncle's family who can play football?"

"More, of course, more." Liu Yu thought of Lu Chu'er and the others. If they didn't have to be on duty, they really didn't want to have a free time. "I still have a lot of good things at my uncle's house, and I'll treat you."

Cao Zhan jumped high, but Liu Jue was very worried that Cao Zhan had never left her for years. Liu Yu persuaded him and said that he would take good care of his nephew and promised to send Cao Zhan back the next day. Liu Jue agreed with ease.

Cao Zhan was only four years old. Liu Yu didn't want him to ride on a horse in danger, so he walked with the horse and took him along. The little guy was very erotic and he was already familiar with Lu Chu'er and the others on the road. In the second half, Cao Zhan had already thrown Liu Yu, the uncle, to Java, and talked and laughed with those "sisters". Lu Chu'er and the others also thought that this little guy was much more interesting than his son-in-law, so he had already discussed the Cuju match and kicked off when he returned home.

Cao Zhan has few playmates, and he plays alone. He can play so many people with him all at once, and he is already overjoyed before he even starts.

"Little pervert."

Liu Yu glanced at Cao Zhan in disappointment and cursed.

Xu Xuanzhu, who was standing beside him, smiled and said, "It seems that Zhan'er is like her husband, and she is very good at coaxing girls. When she grows up, she will definitely be a handsome young man who is loved by women."

Liu Yu frowned and looked at Xu Xuanzhu and asked, "Are you good at coaxing girls for your husband?"

Xu Xuan smiled but didn't answer, and his affectionate eyes made Liu Yu feel even more ashamed.

Before he could enter the door, he saw Han Sheng anxiously waiting. Liu Yu had not been to the chess building these days, and Han Sheng had to come here to find him. When he saw Liu Yu coming back, Han Sheng hurriedly came over.

"Brother Han, what's the matter?"

Han Sheng hurriedly pulled him: "I'm in urgent need, come to the palace with the old man to meet the saint."

Just after noon, Liu Yu had not even eaten food, but Han Sheng was dragged to the palace by Han Sheng. Along the way, Liu Yu asked, it turned out that it was Su Yan's memorial at the Wu Dynasty today. The old emperor specially discussed the re-enlisting of the second prince Su Dian to return to the court at the Wu Dynasty rally, and it seemed that there was still some information.

The Dashun Dynasty's discussion was mainly held in the Wu Dynasty. There was also a morning court, but it was soon abolished. In Liu Yu's opinion, the monarchs and ministers of the Dashun Dynasty were generally lazy. They liked to gather in the palace to discuss matters only once every three to ten days. The Wu Dynasty was held for about two hours, and they were still in charge of food in the middle. This was very humane to Liu Yu's opinion.

The participants in the Wu Dynasty were mainly ministers of the six ministries. Only when the dynasty meeting once every few months would summon officials from all over Chang'an. Liu Yu did not understand why the emperor wanted to summon him into the palace. Could it be that the emperor could see that the memorial was written by him instructed by Su Yan?

When he arrived at the palace, Han Sheng did not take him to the main hall, but walked towards the direction of the Yaqian Hall of the old emperor's study. On the way, he happened to meet Wu You who was sending elixirs to the emperor. Wu You seemed to have something to say when he saw Liu Yu, and maybe he thought it was not the time, so he made a gesture, meaning that he would come over later. Liu Yu thought that there should be significant progress in the development of the glass mirror.

In the Yaqian Hall, the old emperor was watching the memorial made by Su Yan. Liu Yu, Han Sheng and He Mao stood respectfully. The old emperor first sighed a few words, roughly saying that King Yu Su Yan did not forget his brotherhood and was rarely willing to be willing, and expressed his willingness to recall his second son Su Dian back to Chang'an.

The old emperor suddenly looked at Liu Yu and said, "Wen Yan, can you go to Longyou to bring my unfilial son back to Chang'an?"

Liu Yu finally understood the purpose of the old emperor coming to him. His feelings were to ask him to run errands. Longyou was not far from Chang'an, and it was not close, but Longyou area was not small. It was located between the west of Longshan and the Western Regions. It was a deserted place where wars were frequent and birds could not shit. Only genius knew where Su Dian was exiled.

The emperor always called Liu Yu's name Wenyan, which is a title for the elders to show their closeness. The emperor looked down upon him, and Liu Yu had no way to refuse. Fortunately, Han Sheng was by his side and saluted respectfully: "Emperor, Liu You commanded the newlyweds, and he was thin and had never been to Longyou. It may be inappropriate to send him to him... The emperor should send someone else."

Liu Yuxin said that it was still the grandfather of his in-laws who was considerate and knew that going to Longyou was not a good job. He just had a wedding night with his two granddaughters yesterday. Wouldn't he have to let the Han sisters who had just eaten the martyrdom stay in the empty room?

Han Sheng said this more appropriately than Liu Yu's words, making Liu Yu himself seem to be disrespectful to the emperor's grace.

The old emperor smiled and said, "Yes, Wen Yan has lived in Chang'an for a long time. This trip is high and far away. He should really send a capable person familiar with the terrain to go." The old emperor glanced at He Mao and said, "He Aiqing, you might as well take a trip for this trip."

He Mao politely said: "I should live up to my mission!"

Liu Yu also felt that He Mao was more competent in this job. He Mao was down-to-earth and military. He traveled thousands of miles and was not unacceptable to the local conditions. But he couldn't figure it out. If He Mao left Chang'an, who would take care of the Imperial Guard?

Han Sheng expressed Liu Yu's question and asked for instructions: "Emperor, Commander He is the best candidate for this trip, but... If Commander He leaves Chang'an, the Imperial Guard will be dispatched..."

The old emperor glanced at Liu Yu and smiled, "Isn't Wen Yan still there?"

Liu Yu quickly refused: "I... I must not be competent for this task."

The old emperor showed a deep smile and said, "What's incompetent? He Aiqing's trip will last for only three or five days, and only seven or eight nights. Wen Yan, you will temporarily take over the position of commander. Let He Aiqing write a calendar for the next day before leaving, and you can do it at that time."

Liu Yuxin said that the old emperor was so idle that he was looking for something for him. More than 10,000 imperial guards were scattered all over the city. They would not exhaust people when they were inspected every day? However, this job is much easier than going to Longyou. At least they can still rest at sunrise and sunset every day, and they can work as a civil servant.

"I obey the order."

Liu Yu came out of the front hall of Ya, and his legs were a little unmoved. Although he had only been the commander of the Imperial Army for a few days, it was also a worrying job. Thinking of this, he went to Wu You's Astronomy Institute. As soon as he entered the door, Wu You excitedly showed him the glass mirror that he had just made.

Liu Yu did not expect that the craftsmen of Zaoyusi improved the glass manufacturing method so quickly, made flat glass, and plated it with mercury into glass mirrors. If this could be sold, it would inevitably cause a trend in Chang'an City, and a lot of money would be made. However, the cost of making this glass mirror was there, and it was made by the craftsmen of Zaoyusi, so selling was not feasible.

"It's just a glass mirror, nothing fussy. I'll go home and rest first."

Liu Yu was about to leave, but was pulled by Wu You. Wu You looked at Liu Yu up and down and said, "You guy, I thought you would be surprised by this mirror. Have you... seen it long ago?"

"What if I have seen it, what if I haven't seen it?" Liu Yu's answer was plausible.

"No... you can't leave! You finally caught you, you have to stay, tell me how you learned how to make this mirror? Or, let's talk about something else."

Liu Yu felt that this was the rhythm of being dependent on it, and said angrily: "Master Wu, now the right commander of the Imperial Guard, is very busy and has no time to study these with you."

Liu Yu was just talking, and suddenly felt that his eyes were shining directly by the sunlight, so he couldn't open his eyes. He covered his eyes with his hands to avoid some and looked at the light source. Wu Shuo and Qier were holding a mirror in their hands, standing at the door reflecting the sunlight to his face. Seeing Liu Yu's embarrassment, the two smiled happily.

"Is this how you developed the glass mirror?" Liu Yu stared at Wu You and said.

Wu Shuo and Qier walked into the door and sat side by side on the chair beside Liu Yu. They put the glass mirror aside, holding a pack of crisp beans in their hands, which made it very delicious. Qier saw Liu Yu looking at her and reached out and asked, "Do you eat it?"

It is rare that Qi'er is no longer as resistant to him as before, and Liu Yu was relieved. The girl's heart changed rapidly, so it would be better not to look back and seek death.

Wu You took two more lenses and said, "The mirror was made, but this observation mirror is always hard to make and the viewing mirror is not very clear. You can see it and there is a way to improve it."

Liu Yu took the two lenses, a convex lens and a concave lens. The convex lens was well made, but the production of the concave lens was really not good. Liu Yu handed the concave lens back and said, "Please make this mirror more regular first."

Wu You looked at the concave lens carefully, while Wu Shuo, who was beside him, was playing with Qier excitedly with the convex lens. Wu Shuo said in surprise: "Qier, look, the things have become much bigger."

The convex lens is a magnifying glass. Wu Shuo and Qier have never seen it before, so they naturally find it fun. Liu Yu said: "You go out and take it to the sun, put a piece of paper under it, and turn the light into a small dot, which is even more fun."
