"Wizard, genius, my eyes are indeed correct!" Pei Ju laughed excitedly while patting the book in front of him, and his long beard kept trembling with his laughter.

"Master, what are you so happy about, are you so happy?" At this moment, an old servant bent over and hunched up and walked forward with a tray, put a bowl of sour plum soup to relieve heat in front of Pei Ju and smiled. The old servant's face was full of wrinkles, and his head was tied with a bun with few white hair on his head. His turbid old eyes were not very energetic. His hunched figure was also very thin, as if a gust of wind could blow him down.

"Hahaha~ Lao Fu, look at this book. The things on it are amazing!" Pei Ju laughed again when he saw this old servant. He used to be his accompanying student. He had followed him to fight against Turks and Goguryeo, and even rescued him from the battlefield twice. It can be said that he is loyal to him and is deeply trusted by Pei Ju. He will discuss anything with him. Therefore, Lao Fu is not only a servant, but sometimes he also acts as a counselor next to Pei Ju.

Lao Fu took the book and read it, but his turbid old eyes suddenly lit up. Finally, he said excitedly: "No wonder the master praised the person who wrote the book as a genius. This book actually improved the current method of math, making math more simple and clear. If the officials of the Ministry of Revenue use this math to count, it would be much simpler!"

"Haha~ Lao Fu, you are right. This book was printed by the imperial court and distributed to officials at all levels. It is also necessary to be studied by officials at all levels. I am afraid it won't take long. As long as there are things involved in math, this new math will be used. But this is not the most important thing. Look at the name of this book?" Pei Ju said with a proud look on his face, as if the book was written by him, and then he pointed to the title of the book and smiled.

"Mr. Li's arithmetic?" Lao Fu was stunned when he saw the title of the book, and then he whispered to himself, "Since he is called "Mr.", this person should not be very old. Among the people in the Tang Dynasty who are young and famous for mathology, there is probably only Li Chunfeng from the Qin Palace. Could it be that he wrote this book?"

"Old Fu, you really guessed it right. This book was indeed written by Li Chunfeng, but Mr. Li did not refer to Li Chunfeng. Just look at the preface before you will know." Pei Ju said with a smile again. Li Chunfeng dedicated this book to the court some time ago, and at the same time he received strong recommendation from the prince and the King of Qin. Even Li Yuan had read it and was highly praised. He immediately issued an order to engrave the book and then distributed it to officials at all levels for study. It is estimated that after the promotion, the mathematical science of the imperial examinations in the future will be based on this.

When Lao Fu heard this, he looked at the preface in surprise, and his eyes widened. After a while, he looked at Pei Ju and said, "Master, I didn't expect that Li Xiu had such talent. The poems he had written before had been passed down by the Chang'an scholars. Now he has achieved such great achievements in mathematics. In addition, he is valued by the prince, the king of Qin and Princess Pingyang. This person's future is simply limitless!"

"That's true. I lived in my seventies and I have seen countless young heroes, but I only saw a talented young man like Li Xiu in his life!" Pei Ju said with an old face with a dancing expression, and at the same time, he felt very glad that he had promised Li Xiu to marry his daughter.

"Master, this Li Xiu is indeed a talented young man. But I heard that he had no intention of career and refused to recruit the prince and the king of Qin one after another. Instead, he went to Princess Pingyang's mansion to serve as a nameless sacrificial wine. Such a person may not enter the court in the future, right?" Lao Fu said with some doubt at this time.

No one knows Pei Ju's thoughts better than him. Now they have just surrendered to the Tang Dynasty, and Pei Ju is old, so no one can guarantee that he can live for a few more years. Moreover, there are no particularly outstanding figures among the descendants of the Pei family. If Pei Ju falls, the Pei family will decline immediately. So Pei Ju wants to use his daughter to get a relationship with Li Xiu, so that the Pei family can have a support in the future.

"Hahaha~, Lao Fu is wrong. Actually, what I admire most is Li Xiu!" Pei Ju laughed when she heard Lao Fu's words, and a more satisfied expression appeared on her face.

"Oh, why did the master say that?" Lao Fu said strangely.

"Hehe, others may not see it, but how can Li Xiu's thoughts be hidden from me?" Pei Ju smiled proudly and said, "In the eyes of others, Li Xiu may have noble ambitions and disdain to be an official, but in my opinion, he simply does not want to intervene in the battle between the prince and the King of Qin, because he knows the truth that the fight between gods and mortals suffer. Before the prince and the King of Qin compete for victory, I think he will be out of the court!"

Although Pei Ju had a problem with his character, he had to say that his vision was very sophisticated and almost guessed Li Xiu's thoughts. However, he didn't know that Li Xiu really didn't want to be an official.

"It's actually like this!" Lao Fu couldn't help but say in surprise when he heard this, and then he asked in confusion, "But isn't he afraid of offending the prince and the King of Qin? And now he doesn't stand in a row, how can he fully trust him after the prince or the King of Qin fights for the throne?"

"Old Fu, this is Li Xiu's cleverness. He leaned against Princess Pingyang, and the prince and the King of Qin could not do anything about him. Moreover, with his talent, he did not need to show his loyalty to anyone. This is also his greatest reliance. No one else can learn it!"

Pei Ju couldn't help but sigh at the end. Li Xiu could not stand, but he couldn't. In fact, he had turned to Li Shimin some time ago, but after seeing Li Shimin at a disadvantage during this period, he began to have frequent contact with Li Jiancheng again. Although this made him not very famous, for an old fox who had already seen through the world, interests are far more important than reputation.

When Lao Fu heard this, he also took Li Xiu more seriously. After thinking for a moment, he suddenly spoke: "Master, since Li Xiu has such talent and insight, and knows how to protect himself, if he becomes an official in the future, he will definitely be a great minister. Such a person must not give up. Look at the marriage between Yi Niang and Li Xiu..."

At the end of the day, Lao Fu's old eyes also had a shrewd look, and Pei Ju said firmly: "The marriage between Yi Niang and Li Xiu must be done, and it must be done as soon as possible. Anyway, Li Jing took the initiative to propose this marriage, and he had already agreed to get engaged last time, so he would not want to regret it!"

"The master is wise. It is her blessing to marry such a young hero!" Lao Fu said with a smile when he heard this. Yi Niang was just a maid. Even before she was fifteen years old, Pei Ju didn't know that she had such a daughter. It would be extremely cost-effective to use such a concubine's daughter to exchange for a promising young hero like Li Xiu.

"But I'm still a little worried about Li Xiu..." Pei Ju suddenly spoke again at this time. He remembered that after Li Xiu and Li Jing and his son had a falling out last time, he had mentioned the marriage with Li Xiu, but the other party refused to admit it at all, and instead asked him to find Li Jing.

When Lao Fu saw the face of his master, he knew what he was worried about. After pondering for a moment, he suddenly thought of a solution. He immediately fell into Pei Ju's ear and said a few words. Pei Ju was stunned at first, then happy again, and finally said in a little embarrassed manner: "Lao Fu, is it a bit inappropriate to do this?"

"Master, reputation is false, and it is true that Parent Pei is prosperous. And you have done everything you should do. Unless Li Xiu doesn't want reputation, he can only accept it obediently!" Lao Fu smiled treacherously. Shamelessness is invincible. This old guy understands this principle more than anyone else.

Hearing Lao Fu say this, Pei Ju lowered her head and pondered for a moment, and finally nodded with gritted teeth. Then he thought of something and said again: "But if you want to do this, you still need the cooperation of the wardrobe. What is she doing now?"

"Master Qibing, since Li Xiu became famous, Lao Nu has arranged a residence for Yi Niang and arranged a maid to take care of her. During this period, she has been staying in her place to read and write, and she has not done anything special." Lao Fu smiled and reported that Yi Niang is the daughter Pei Ju wants to marry Li Xiu, and she is also Pei Ju's youngest daughter.

The status of a concubine's son and daughter is only a little higher than that of a servant. Don't think that this is just a joke. For example, like Pei Ju, he has too many sons and daughters, most of whom are concubine's sons and daughters. Some of them have a reputation are better, but those who have no status are really not much higher than those of a servant, and some even have to work in person, otherwise they will not even have enough food to eat. In comparison, Li Xiu and Qi Niang are not the worst treatment in Li Jing's mansion.

"That's good!" Pei Ju said with some confidence when she heard this. For the daughter of Niang Yi, he only went to see Niang Yi after Li Xiu made a big splash on the Lantern Festival and told her that she was going to marry Li Xiu. He remembered that Niang Yi had no objection or consent at that time. The eyes of Niang Yi looked at him were full of indifference, which made him feel very uncomfortable.

"Forget it, I'd better go see her. By the way, I'll explain some things!" Pei Ju suddenly spoke again. Perhaps it was because of the look of the look of the lady in the clothes looking at her last time that Pei Ju felt a little uneasy, so she decided to visit her in person.

"Then I will lead you the way!" Lao Fu nodded immediately when he heard this. Pei Ju had never been to the new residence he arranged for the wardrobe, so he definitely didn't know the way.
