Liu Zhao gave Qi Fang a chance, and Liu Yu barely completed the task this time, so he rarely went home, and went to visit his sister and nephew by the way, and told Liu Jue the truth about Qi Fang's proposal by the way.

The promotion of Liu Yu's identity made Liu Jue able to raise his head in the Dingguo Marquis Mansion, and the people in the other courtyards did not dare to be too embarrassed. Hearing the news that Qi Fang came to propose marriage, Liu Jue was still a little moved on his face, especially when he heard that Qi Fang and his old father were competing, Liu Jue sighed, mentioning that Qi Fang couldn't even catch Liu Zhao's stick back then, and what she cared about was whether it could be promoted after the worst incident.

"Little brother, you said he ...... How sure are you that you will be promoted to a general? Liu Jue asked.

"It should be very graspable, but it depends on how long it takes, you said that if he is promoted to general in his seventies and eighties, can you afford to wait?"

Liu Jue glanced at Liu Yu with a smile and said, "When did you learn to make fun of your sister?" Younger brother...... You'd better help him a little more. ”

If you want to help Qi Fang, you don't need Liu Jue to say that he will do it too, I am afraid that there will be no war in the peaceful years, and it will be difficult to be promoted to a partial general. After a conversation, parting, Cao Zhan had to pull Liu Yu to play football.

"Uncle is very busy right now." Liu Yu said, "If you don't go to your uncle's house, how about your uncle find someone to play with you?" ”

Cao Zhan's eyes widened and asked, "Are there a lot of people in my uncle's family who can play football?" ”

"Much, of course much." Liu Yu thought of Lu Chu'er and them, if they didn't have to be on errands, they really didn't want to be idle for a moment, "Uncle still has a lot of good things at home, and my uncle will entertain you." ”

Cao Zhan jumped high, but Liu Jue was very worried, Cao Zhan had never left her all these years. Liu Yu persuaded him, saying that he would take good care of his nephew and promise that he would send Cao Zhan back the next day, and Liu Jue agreed with relief.

Cao Zhan was only four years old, and Liu Yu didn't want him to be in danger on horse, so he led the horse on foot and took him along. The little guy is articulate, and he is already familiar with Lu Chuer and them on the way, and in the second half of the journey, Cao Zhan has already thrown Liu Yu's uncle to Java, and he is talking and laughing with those "little sisters". Lu Chu'er and the others also thought that this little guy was much more interesting than their own uncle, and they had already discussed on the way to kick the Juju Race when they returned home.

Cao Zhan has few playmates, and he plays a one-man juju, and he can play with so many people at once, and he can't be happy before he starts.

"Little pervert."

Liu Yu glanced at Cao Zhan and scolded.

Xu Xuanzhu on the side said with a smile: "It seems that Zhan'er, like her husband, is very good at coaxing girls, and when she grows up, she must be a charming and suave boy who attracts women." ”

Liu Yu frowned and looked at Xu Xuanzhu and asked, "Is your husband very good at coaxing girls?" ”

Xu Xuanzhu smiled but did not answer, and his affectionate eyes made Liu Yu feel even more embarrassed.

Before he could enter the door, he saw Han Sheng's anxious figure waiting for him. Liu Yu hadn't been to the chess building for a few days, Han Sheng could only come here if he wanted to find him, and when he saw Liu Yu coming back, Han Sheng hurriedly greeted him.

"Brother Han, what's the matter?"

Han Sheng hurriedly pulled him: "Urgent, go into the palace with the old man to face the saint." ”

At this time, it was just after noon, and Liu Yu hadn't even eaten yet, so he was dragged to the palace by Han Sheng. Along the way, Liu Yu asked, it turned out that Su Yan caused the waves in the afternoon dynasty today, and the old emperor specially discussed the matter of rerecruiting the second prince Su Dian to return to the dynasty at the noon dynasty assembly, and it seems that there is a following.

The court discussion of the Dashun Dynasty was mainly based on the afternoon court proceedings, and there was also an early dynasty, but it was soon abolished. In Liu Yu's view, the monarchs and ministers of the Dashun Dynasty are generally lazy, and they like to gather in the palace to discuss matters only after three to ten days. It was carried out for almost two hours before and after the noon dynasty, and the rice was in charge of the middle, which was very humane in Liu Yu's opinion.

The participants in the deliberations of the afternoon dynasty were mainly ministers of the six ministries, and the officials of Chang'an would be summoned only once every few months. Liu Yu didn't understand why the emperor wanted to summon him to the palace, could it be that the emperor saw that the memora was written by Su Yan at his behest to do so?

When he arrived at the palace, Han Sheng did not take him to the main hall, but walked in the direction of the old emperor's study, Yaqian Hall. On the way, I happened to meet Wu You, who was sending pills to the emperor, and Wu You saw Liu Yu as if he had something to say, and he might feel that it was not the right time, so he made a gesture, meaning to come over in a while. Liu Yu thought that there should be significant progress in the development of glass mirrors.

In the Yaqian Hall, the old emperor was watching Su Yan's recital, and Liu Yu, Han Sheng, and He Mao stood respectfully on the side. The old emperor first sighed a few words, roughly saying that Su Yan, the king of Yu, did not forget the brotherly love, and it was rare to have a heart, and expressed his willingness to recall his second son Su Dian to Chang'an.

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

Liu Yu finally understood the purpose of the old emperor looking for him, and his feelings were to find him to run errands, Longyou is far from Chang'an, and it is not far from Chang'an, but the Longyou region is not small, located between the west of Longshan and the Western Regions, a border wasteland where wars are frequent and birds don't, and the ghost knows where Su Dian was exiled.

Every time, the emperor called Liu Yu's cousin Wenyan, which is a kind of title from the elders to the younger generations to show closeness. The emperor could afford it, Liu Yu had no way to refuse, fortunately Han Sheng was beside him, and saluted respectfully: "Your Majesty, Liu You is the newlywed Yan'er, and he has a thin body, and he has never been to the land of Longyou, so it may be inappropriate to send him...... The emperor should send someone else. ”

Liu Yuxin said that his in-laws and grandfathers were compassionate, and he knew that it was not a good errand to go to Longyou, and he only spent candles in the cave room with his two granddaughters yesterday.

Han Sheng said this more appropriately than Liu Yu spoke, making Liu Yu himself seem to not miss the emperor's grace.

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

He Mao saluted and said: "The minister should live up to his mission!" ”

Liu Yu also felt that He Mao was more capable of this errand, He Mao was down-to-earth and had a military background, and he traveled thousands of miles without being accustomed to the water and soil, but he couldn't figure it out, if He Mao left Chang'an, who would care about the Imperial Forest Army?

Han Sheng expressed Liu Yu's questions and asked: "Your Majesty, Commander He is the best candidate for this trip, but ...... If Commander He leaves Chang'an, the matter of the deployment of the Imperial Forest Army ......"

The old emperor glanced at Liu Yu and said with a smile: "Isn't there still Wen Yan." ”

Liu Yu hurriedly excused himself and said, "Minister...... Absolutely not up to the task. ”

The old emperor smiled meaningfully and said, "Why can't you do it?" He Aiqing's visit is no more than three or five days, and it is no longer than seven or eight nights, Wen Yan, you will temporarily take over the position of commander, and let He Aiqing write down a day's calendar before leaving, and you can do it at that time. ”

Liu Yuxin said that this was the old emperor's panic to find something to do when he saw that he was idle, and more than 10,000 people of the Imperial Forest Army were scattered all over the city, and they didn't tire people to death after patrolling every day? However, this errand is still much lighter than going to Longyou, at least every day can still be sunrise and sunset, and work as a civil servant.

"Obey."

Liu Yu came out of the Yaqian Palace, his legs were a little unable to walk, although the temporary commander of the Imperial Forest Army was only a few days, it was also a sad errand. Thinking of this, he went to Wu You's astronomical institute, and as soon as he entered the door, Wu You excitedly showed him the glass mirror that had just been made.

Liu Yu didn't expect that the craftsman who made the imperial division would improve the manufacturing method of glass so quickly, make flat glass, and plate it with mercury to turn it into a glass mirror. If this can be sold, it will inevitably cause a trend in Chang'an City, and a lot of money will be earned. But the cost of making this glass mirror is there, and it is made by the craftsmen who make the imperial division, and it is not feasible to sell it.

"It's just a glass mirror, there's no fuss, there's nothing else I'll go home and rest first."

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

"How have you seen it, but what if you haven't seen it?" Liu Yu's answer was plausible.

"No...... You can't go! I finally caught you, you have to stay, tell me how to make this mirror, where did you learn how to make it? Or, tell us something else. ”

Liu Yu felt that this was the rhythm of being relied upon, and said angrily: "Master Wu, as the right commander of the Imperial Forest Army now, he is very busy, and he has no time to study these with you." ”

Liu Yuzheng said, suddenly felt that his eyes seemed to be exposed to direct sunlight, and he couldn't open his eyes, covering his eyes with his hands to avoid some looking at the light source, Wu Shuo and Qi'er were holding a mirror in their hands, standing at the door to reflect the sun's light on his face, seeing Liu Yu's embarrassment, the two smiled very happily.

"That's what you've come up with for glass mirrors?" Liu Yu stared at Wu Youdao.

Wu Shuo and Qi'er walked in the door, sat side by side on the chair next to Liu Yu, put the glass mirror aside, and each held a pack of crisp beans in their hands. Seeing Liu Yu looking at her, Qi'er stretched out her hand and asked, "Do you want to eat?" ”

It's rare that Qi'er is not as resistant to him as she was at the beginning, Liu Yu can be regarded as relieved, the girl's heart is changing rapidly, don't look back and look for death and life.

Wu You took two more lenses and said: "The mirror is made, but this observation mirror is always not well made, and the vision is not very clear. ”

Liu Yu took the two lenses, one convex lens and one concave lens, the convex lens was made well, but the production of the concave lens was really not hot, Liu Yu handed the concave lens back and said: "First make this mirror more regular." ”

Wu You took the concave lens and looked at it carefully, while Wu Shuo on the side was playing with Qi'er with interest with the convex lens, Wu Shuo was pleasantly surprised: "Qi'er, look, things have become a lot bigger." ”

The convex lens is also a magnifying glass, Wu Shuo and Qi'er have never seen it before, so they naturally think it's fun. Liu Yu said: "You go out and hold it to the sun, put a piece of paper underneath, and turn the light into a small dot, which is more fun." ”

Wu Shuo and Qi'er glanced at each other, excitedly took the convex lens out of the lens to do the experiment, and not long after, Qi'er came back with a half-burned paper and said, "The paper is burning." ”
