The auction house in the underground market was burned to the ground, and Concubine Xue and many people in the industry were killed, which caused quite a stir.

However, after all, it was a shady thing, but they didn't dare to put it on the table, but someone dared to break the rules of the underground market, which attracted their attention.

They sent a lot of people to investigate Li Yun's whereabouts, but this person seemed to have disappeared, evaporated from the world, and his identity and personal information in the auction were fake, which really made the people in the underground market fall a lot.

……

After Li Yun left the underground auction house, he quietly returned to the house, as if nothing had happened.

Recently, there has been nothing to do, Li Yun is reading books at home, raising flowers, and going outside from time to time, accompanied by his personal maid Qing'er.

As he spoke, the day of the opening of the altar and the preaching of the court also came.

Li Shimin opened up his way widely, allowing people with virtue and prestige in the world to come to the imperial city to open an altar to discuss the Tao, but over time, the essence of the opening of the altar and the Tao changed.

Everyone discussed the way of literature and explored the way of governing the country, but the discussion of the past two years has become an important means for them to criticize the monarch.

Some people rely on their knowledge to comment on the present world in public and talk freely, but they don't know that their remarks are just talk on paper.

When it comes to governing the country, they talk endlessly, but the real reality is that it is difficult to put it into practice.

The place where the altar was opened is located on the square outside the Chengtian Gate, which is connected to the imperial city and the Suzaku Street outside, which can be watched by the people, which is a real event to be shared with the people.

It's just that if anyone loses in the argument, it is not only in front of the hundred officials, but also the people of the whole city.

As time passed, a large number of people gathered in the square, and although many people were illiterate, they still came to see the excitement.

And with the arrival of Li Shimin and hundreds of officials, it means that the opening of the altar has officially begun.

In addition to the monarchs and ministers, there were also princes and princesses, as well as Wang Tong, a literary Confucian who wanted to preach, and his disciples.

After everything was ready, Li Shimin said, "Let's start."

Wang Tong stepped forward and respectfully saluted Li Shimin on behalf of the Confucian scholars, and said: "Today, the altar is open to discuss the Tao, and the theme that the minister Wang Tong wants to discuss is 'scripture', please send someone to discuss it with the minister."

On the Tao, the most particular thing is a word, since you want to talk about it, it is to talk with others, if you talk about it yourself, it is not called the Tao, but the Tao.

The presiding masters of many temples in Chang'an City will preach regularly.

Li Shimin immediately nodded in agreement, and said to Li Chengqian: "Prince, Wang Tong was the prince's teacher in the past, you can come forward to discuss with him, and you can also test your level?"

Li Chengqian's heart was shocked, he used to be his teacher, you must know that he is Wang Tong, he knows all the ancient and modern classics and scriptures, and even the principal of Guozijian has to respectfully perform etiquette when he sees him.

But Li Shimin said so, and Li Chengqian dared to disobey his orders, so he had to step forward and say, "Today, I will discuss with the teacher and ask the teacher for advice."

Wang Tong looked at the former students, not only did not let the water, but became more severe, and said before he started: "Today's discussion of the Tao is a major matter of the country, although I am the prince's old teacher, but you are the prince, I am a courtier, but I must also follow the outline of the monarch and the minister, not to be overcome, the prince's words are really a big mistake, should be changed."

To put it simply, the prince did not call himself the prince when he first came, but used "I" to express his respect for Wang Tong, and instead of winning Wang Tong's understanding, he was reprimanded.

Li Chengqian's face was a little red, Wang Tong was really the same as before, meticulous, and he couldn't tolerate the slightest mistake, even if it was a slip of the tongue.

"Student...... The palace has been taught, please speak first. Li Chengqian said.

As Wang Tong said just now, the theme of today's argument is: Sutra.

The so-called classics are the scriptures of a hundred schools, which are different from the four books and five classics, which are to be examined by the imperial examination, that is, the four books and five classics are at a higher level, like the level of high school and college, and the classics are basic knowledge.

In other words, it is our enlightenment reading materials today, such as Sima Xiangru's, Shi You's, Yangxiong's, Cai Yong's, Ban Gu's, etc., these are all enlightenment readings of the scriptures, the Four Books and the Five Classics are classics, and these are the foundations, and everyone must learn and comprehend the books.

Of course, Confucians like Wang Tong will not discuss literacy and hyphenation, these are all pediatrics.

"The prince respects the teacher, then the minister is not welcome." Wang Tong said, "Dare to ask what are the three outlines proposed in the Han Dynasty chapter of the crown prince? ”

Li Chengqian replied: "The king is the minister, the father is the son, and the husband is the wife."

Wang Tong nodded, and asked again: "Which of the three outlines is lighter?" Which is more important? Which is secondary? ”

"Of course, the monarch and the minister are the most important, the husband and wife are the lightest, and the father and son are secondary." Li Chengqian replied calmly.

"The minister is you, the husband is you, the son is you, and all three are you, so what is the importance?" Wang Tong suddenly wanted to ask.

Wang Tong's question is really sharp, what he means is that since you say that the monarch and the minister are the most important, the father and the son are the second, and the husband and wife are the lightest, but you yourself are the minister, the son, and the husband, since they are all one person, how can you say that you are valuable? !

In this way, there is a suspicion of sophistry, but when you think about it, it makes perfect sense.

If you admit it, it is a denial of your own statement that the monarch and the minister are valuable, so no matter what Li Chengqian says, it is a contradiction.

Sure enough, Li Chengqian was dumbfounded for a while, he didn't know how to say it well, and he just started to make Li Chengqian deflated, and this Wang Tong still didn't talk about the teacher-student relationship at all.

Many people were secretly glad on the side, but it was not Wang Tong who they were facing just now, otherwise, they would be in an embarrassing state.

"Please answer the prince." Wang Tong raised his tone again, which was very aggressive.

"Hongu ...... I can't answer that. Li Chengqian's cheeks were beaded with sweat, and he only felt embarrassed.

"Since the prince can't answer, then ask someone who comes up to answer to talk about it?" Wang Tong said.

I thought I was talking about the Tao when I knew it, but I thought it was a fight if I didn't know.

Li Shimin was a little disappointed when he saw that the prince was defeated in a few words, but that Wang Tong was also really rampant, thinking that he knew the classics, so he didn't take others seriously.

For a while, no one stepped forward to be humiliated at all, Li Shimin had to pin his hopes on Li Yun, and Li Yun had no choice but to shake his head and say, "I'll come!!"
