After that, I don't know how long it took, Wu Weiyi had been living in this official residence, and he had tried to go out of the city gate many times to find Princess Nishikori, but he was rejected by the guards at the city gate.

Since Wu Weiyi had already learned about the current situation in Shu from the mouth of the old King of Shu at this time, he naturally understood that the reason why Wang Zijiang wanted to prevent him from leaving the city must be to prevent him from having too much contact with other people.

Wu Weiyi pondered, since I can't get out of this fish city now, why don't you try to let Princess Nishikori enter the city? But how do you get her?

Although Wu Weiyi is not a person from the Spring and Autumn Period, he also knows that in the Spring and Autumn Period, all people with some knowledge have the style of opening the altar to teach and discuss the Tao. Therefore, he pondered why he didn't follow the example of those great sages, and also opened a faction, with some mathematical philosophical principles, to stand out from the rest. On the one hand, it is better than the addiction of a saint, and on the other hand, it is better to build a nest to attract phoenixes, and want to let the princess enter the city for a while.

So, Wu Weiyi opened an altar to teach in his official residence in the past few days. For the sake of safety, at first, Wu Weiyi originally only recruited a few young slaves from his own house and the surrounding market as students, but he never thought that after three or five days, he would already be in the market. In several markets around the city, a large number of Chinese people knew that there was a place where they could learn their skills, so they rushed to listen to the "holy word". The so-called foreign immortals are good at chanting scriptures, and Wu Weiyi has become a person who has attained the Tao in Yuyu City.

What did Wu Weiyi say? Why is it so much sought after by so many people?

It turned out that Wu Weiyi knew that although the people in the Spring and Autumn Period were active in thinking at this moment, they were still in power after all. It is said that it is the remarks of celebrities from all walks of life that it is "a hundred schools of thought contending", but in fact, it is more appropriate to say that it is "a hundred schools of thought competing for favor". Therefore, it was the academic fashion of the time for ideas to serve domination.

But Wu Weiyi has no such concerns, he is just a passerby in time and space, and he has no intention of "competing for favor" at all. He wanted to teach the local people something more tangible, such as mathematics, geometry, physics, and logic.

And this knowledge is extremely useful to those who work as a living in the fields of labor. In addition, Wu Weiyi's lectures are often evidenced by production examples, so his doctrine quickly spread everywhere.

One day after class, Mo Di was helping Wu Weiyi pack up his utensils, and Wu Weiyi was also about to go into the house to take a lunch break, but a student came up to him and asked:

"Dare to ask Mr. a question, and I hope Mr. will give him advice."

"Go, go, where did the white scholar come from, how can he not understand the rules like this? If everyone is like you, please go east and west, and the teacher will not be exhausted by you......"

I only heard Brother Mo say angrily on the side, but was stopped by Wu Weiyi. Wu Weiyi looked at the man fixedly, feeling as if he was déjà vu, but he didn't know where he had seen it. I saw that this student was beautiful and had a complexion like congealed cream, and although he was dressed without too much whitewashing, he did not look like an ordinary person.

Wu Weiyi's doubts about students have always been unrejected, but since he lectured, no one has come to ask questions elsewhere, and now this is the first case.

"If you have any questions, please let me know."

I only heard the white-faced little boy ask:

"Listening to Mr. Lecture is like drinking alcohol, which is fascinating. But dare to ask Mr., there is a sun and moon in the sky, people are divided into men and women, and everything has yin and yang. ”

Wu Weiyi thought for a while and replied:

"The number is positive and negative, the positive number is yang, and the negative number is yin."

When the white-faced boy heard this, he asked with a little excitement:

"Is there a difference between the yang number and the yin number?"

Wu Weiyi laughed when he heard this, and said:

"Hahaha, if you talk about it absolutely, the number of yin and yang is not big or small. And the inverse of the yin number is also a yang number, and the inverse of the yang number is also a yin number. Since they are each other, how can they distinguish between the big and the small, the high and the low? ”

After hearing this, the white-faced boy bowed respectfully to Wu Weiyi, and then continued to ask:

"If so, isn't it yin and yang? Male and female? ”

When Wu Weiyi heard this, he looked at the white scholar again, and said with a smile:

"Hehe, how can there be no difference between yin and yang? The number of yin is like the earth, and the number of yang is like the sky. Heaven and earth are of the same origin as each other, and heaven and earth are opposed to each other and transform all things. In this way, is heaven and earth the surface of each other, and is the heaven or the earth great? ”

When the white-faced scholar heard this, he said happily:

"Listening to Mr.'s words, it's like an initiation, which makes me suddenly open my mouth! But...... Sir, now you have a lecture in your mansion, and the teachings you are preaching may not be what some people want to hear. Therefore...... Sir, please take care. ”

As soon as Wu Weiyi heard this, he immediately raised his vigilance and asked with a serious face:

"You...... Who is it? ”

The man leaned over again and whispered:

"Xiaosheng has been listening to lectures here for many days, and Mr. Zhi is a great sage in the world. However, if he is in trouble in the future, he can go here with this silk, and then he will have others to help him. ”

As soon as he finished speaking, he saw that this person left a rather beautiful silk cloth, but before Wu Weiyi could see what was embroidered on it, the person had already got up and left immediately. Wu Weiyi saw that the man had already gone away, and it was too late to catch up. I only picked up the handkerchief in my hand and looked at it carefully inside and out. I saw that although the pattern on this silk handkerchief is simple, it also shows the ingenuity of the people who use the workers, and the eyebrows are expressive. Specifically, it depicts a market scene of several nomadic men selling horses against a city wall.

"Brother Mo, do you recognize this place?"

Brother Mo was originally rectifying the case under the hall, and when he heard the master calling him, he leaned over to take a look, and said casually:

"Oh, I know this place, it is a horse dealer opened by a few Qiang people, the land of Bashu does not produce good horses, but trade and commerce should be dominated by horses, so here in the west of the city, there are many Qiang people selling horses. Hehe, these sights are not surprising. ”

Wu Weiyi only shook his head after hearing this, still not understanding the meaning. At this time, I only heard the guard in front of the door report:

"Sir, it has been reported that His Royal Highness the Prince's car is heading towards the official residence."

Wu Weiyi was shocked again, put the silk handkerchief on the case and went out to greet the prince's car. Before he walked out of the courtyard, he saw that Wang Zijiang had already come to the door. Wu Weiyi hurriedly stepped forward and said:

"Wu Weiyi has seen His Royal Highness the Prince."

"Immortal pardon, huh? It turns out that Shangxian's surname is Wu Weiyi? ”

Wang Zijiang asked suspiciously, and Wu Weiyi replied:

"Oh, in the next book, he was just a civilian, and then he went to Qingcheng Mountain to find an immortal apprentice, and met the Jinwu God Nether Patrol, and was assigned one or two by him, and then he was promoted to immortal."

Wang Zijiang couldn't help but nod when he heard this, and said with emotion:

"Shangxian still has such a situation, it's really enviable!"

Wu Weiyi also didn't expect that his pretending to be a ghost these three times would be so easy to use, and he was a little happy in his heart, but he couldn't express it beyond words:

"Your Royal Highness, may I ask why you are visiting the place today?"

Wang Zijiang smiled and waved his hand, and replied:

"It's okay, it's just that the military affairs are urgent in the past few days, and I didn't have time to take time to visit the immortals, so I returned triumphantly yesterday. Therefore, I am free today, and I specially led these famous people in my Shu to visit the immortals together. ”

Wu Weiyi felt a little curious when he heard this, and asked:

"Oh? In the past few days, I have only cared about teaching and lecturing here, but I have never thought that His Royal Highness the Prince is leading troops outside. But you don't know who you are fighting against? ”

Wang Zijiang replied with disdain on his face:

"It's not a big deal, it's just some slaves who want to escape from work and rest, instigated by the gangsters in Shu who want to defect to other states in an attempt to rebel. Now they have been suppressed by my troops and escorted back. ”

Wu Weiyi couldn't help but be taken aback when he heard this, and asked in a low voice:

"I don't know...... What is the prince going to do with these 'thieves'? ”

Wang Zijiang said disappreciatively:

"When it comes to the sacrificial ceremony, kill all the sacrificial gods to set an example."

Wu Weiyi's heart was shocked again:

"This prince is so cruel and unkind, if the Shu Kingdom entrusts this lord, I am afraid that the difficulties of the Shu people will never end!"

Wang Zijiang saw that Wu Weiyi had no reaction at the moment, so he immediately said:

"Huh? Immortals, why are we talking here? How about we go into the house and talk? ”

Wu Weiyi reacted at this time:

"Oh! Yes, yes, His Royal Highness the Prince, come, this way, please! ”

After speaking, Wu Weiyi immediately led Wang Zijiang and everyone into the lobby. Wang Zijiang was naturally introduced to the main seat, and Wu Weiyi sat in the second seat. The others sat down in order of humility.

When the servants under Wu Weiyi's sect saw Wang Zijiang, they were all chilled and frightened, and they didn't dare to serve badly, so they came to the hall to serve tea and fruits to everyone, and they were busy for a while.

Wang Zijiang waited a little impatient at this time, and shouted loudly to those subordinates:

"How can such a trivial matter take a long time?! Don't get out of here! ”

When Mo Di and the others heard this, they immediately knelt on the ground, and hurriedly retreated.

Wu Weiyi saw that the atmosphere was a little serious, so he asked the prince:

"Looking at His Highness's expression, his eyebrows are tightly locked, as if he has unresolved doubts, I don't know what is going on?"

Wang Zijiang replied:

"Shangxian is really a good eye, but the prince of Japan has some unresolved doubts, so he has come to consult Shangxian."
