Li Nuo had just arrived at the Song Mansion and happened to meet Song Muer and Song Jiaren who were about to go out. They were going to Li's house to find him. Fortunately, they met him at the door, otherwise they would have made the trip in vain. A moment later, in a small courtyard somewhere, Song Muer lay on the table, supporting her head with both hands, and said: "Brother Li Nuo, you might as well live in our house, so that we don't have to run around every day... " Li Nuo smiled and said nothing. He was not a son-in-law. There was no special reason. Of course he couldn't live in Song Mansion forever. The Li family is a single generation, and it is absolutely impossible to expect him to carry on the family line and spread the branches. Mu'er is still young, so of course she doesn't understand these things. Li Nuo did not continue this topic, pointed to a question on her booklet, and said: "Let's take a look at this question first..." I don’t know if Song Muer’s mathematics teacher was so kind. This time, her after-school homework only had one question, and it was not very difficult. The question was about a group of Daxia cavalry who needed to drive their horses to the river first. Drink water, and then rush back to the military camp. The question gives the speed of the cavalry and the distance between places. It asks about the optimal route and the fastest time. This is a good question. Soldiers are very valuable, and speed and efficiency are extremely important on the battlefield. At critical times, a quarter of an hour's time difference can determine the outcome of a war, and even affect the rise or fall of a country.
In Li Nuo's eyes, this is the simplest problem of the general drinking his horse, and the primary school students of later generations will know it. However, the solution to this problem is not any of the "nine numbers". It also involves an axiom, which is unknown in the Daxia mathematics community. It is a bit troublesome for Li Nuo to explain the axiom. Song Muer held her chin with one hand and asked, "Why is the line segment the shortest between two points?" Li Nuo is not a mathematics major. When the teacher taught them, he just told them that they only need to remember the axioms and do not need to know why. He asked the maid of the Song Dynasty to find two wooden sticks and some thread for sewing clothes, insert the two wooden sticks into the ground as two points, and let her practice it herself. Compared to the six-year-old Song Mu'er, it was much easier for Song Jiaren to understand this problem. Although she couldn't give a specific reason, common sense told her that going straight would definitely be faster than going round and round. As soon as Li Nuo finished telling them this topic, Song Yu walked into the small courtyard, invited him to come over for dinner, and thanked him for his rescue today. Li Nuo was actually quite embarrassed, but couldn't stand Song Yu's insistence, so he had to agree. In a small courtyard in Song Mansion, Li Nuo met Brother Zhou Yu again. An hour ago, they were at loggerheads with Song Yu, but now they lost their arrogance and arrogance. They lowered their heads and stood behind a middle-aged man like minions. Song Yu was obviously surprised that the two of them appeared here. He frowned. Just as he was about to say something, Song Lian glared back. The middle-aged man looked at Song Lian and said apologetically: "Brother Song, I'm really sorry. It's my fault in raising my son. Today I brought these two bastards here to apologize to my nephew. Please accept these small gifts. " Song Lian said hurriedly: "Brother Zhou, please don't say that. It's normal for young people to be angry and fight. We didn't come here like this back then. Besides, this rebellious son of mine is also at fault. You must bring these gifts." go back……" The middle-aged man did not mention the gift again, smiled and said: "Speaking of those days, every time you suffered a loss, we would be beaten by Miss Song Zhen the next day. It was really a painful memory..." Song Lian also laughed and said, "We were practicing tactics back then. How could these brats fight over a brothel girl? It's really an embarrassment to our family!" The two of them glanced at their sons in unison. Brothers Song Yu and Zhou Yu shivered and buried their heads lower. Li Nuo learned from their conversation that the Zhou family and his son were here to apologize. Zhou Yu's father and Song Yu's father not only knew each other, but also seemed to have some friendship, and they looked like they were having a good time talking to each other. "You bastard, you still haven't apologized!" The middle-aged man shouted lowly. Brother Zhou Yu trembled, walked up to Song Yu, lowered his head and said, "I'm sorry."
Song Lian gave Song Yu a look, and Song Yu trembled and said quickly: "It's okay, it's okay. I just got three sticks. I don't take it to heart at all..." With the help of both fathers, Song Yu and Zhou Yu easily reached a reconciliation, at least on the surface. In order to show that he really didn't care, Song Yu also invited the two of them to have dinner together. Brother Zhou Yu had just been tortured with the cane, and Song Yu thoughtfully asked someone to place soft pillows on their chairs. After sitting down, Zhou Yu looked at Li Nuo and asked, "Brother Song, who is this..." In the Chang'an County Government Office, it was this man who sentenced them to the rod. Zhou Yu thought he was an official of the Chang'an County Government Office, and was still amazed at how young this official was. He did not expect to see him again in the Song Mansion. Song Yu put his arms around Li Nuo's shoulders, with a proud expression on his face, and said, "Let me introduce you to you, this is my brother-in-law." Brother Zhou Yu was shocked when he heard this. Song Yu has three sisters, two of whom are still children, so the person in front of her can only be Song Jiaren’s husband, and Song Jiaren’s husband is not the son of Li Xuanjing, the minister of Dali Temple? Their brothers can be regarded as the sons of officials, but they are far from comparable to each other. This is the top powerful son of Chang'an. If Song Yu has such a good relationship with him, wouldn't it be possible for him to go sideways in the future? Thinking of this, Zhou Yu immediately picked up the wine glass and said respectfully to Song Yu: "Brother Song, this matter is all my fault. I will punish myself with a drink!" Seeing Zhou Yu's sincere attitude, Song Yu was a little embarrassed, so he also picked up his wine glass and said, "I am also at fault in this matter, so I'll have a drink with you." "My fault, my fault, I punish myself with three drinks!" "I was also at fault, I'll have three drinks with you!" … Li Nuo took a sip of the wine and felt that the wine was extremely spicy. After one sip, he put it down. Zhou Yu and Song Yu drank one glass at a time and one at a time. After ten glasses, they became less fluent in their speech and began to hook their shoulders. Called brothers, the two of them are more like brothers than Zhou Tao who is sitting idle aside. After three rounds of drinking, the chatterbox gradually opened up. Zhou Yu took another sip of wine. Although his expression was a little reluctant, he still patted his chest and said, "We are all brothers. It was my fault in the past. I will never compete with you for the girl..." Song Yu also patted his chest and said loyally: "No, no, no, I'm just a woman, so I'll leave it to you." "Here you go." "Come on..." … The two of them were saying things to each other, giving way to each other, but no one could give in to the other. Zhou Yu thought for a moment, looked into Song Yu's eyes, and suggested: "How about together?" The two looked at each other, imagining certain restricted-level scenes in their minds. The hair on their bodies stood up, and they shook their heads in unison. Although their relationship has grown by leaps and bounds, it hasn't reached the point where they share a woman together. The scene was so jarring that I couldn’t even think about it. But the atmosphere was so heightened that none of them felt embarrassed to monopolize the mandarin duck girl.
Their eyes looked at each other awkwardly again, and they suddenly thought of something at the same time, and they all looked at Li Nuo. "How about I introduce Miss Yuanyang to my brother-in-law?" "Only Brother Li is worthy of such a beautiful woman..." Song Yu was reluctant to give up the Yuanyang girl to Zhou Yu, but his brother-in-law repaid kindness with kindness and was kind to him, which was considered a kind of repayment. Marrying a beautiful woman ruined his life's happiness. As a member of the Song family, Song Yu felt guilty and wanted to make up for it. Zhou Yu was reluctant to give up the mandarin duck girl to Song Yu, but Li Nuo was the son of the minister of Dali Temple, and he also wanted to get involved with this top dignitary in Daxia, so he could only reluctantly part with her. Hearing what they said, Li Nuo stopped picking up the food. A figure flashed through his mind, and his chest began to hurt again. He waved his hands repeatedly: "No, no, you can do it yourself. I don't have this hobby... …”
