For Zhang Zheng, this is just something that any junior high school student in the future can come up with. The simplest knowledge of chemistry plus a little psychological means is really not worth mentioning.

But Li Shimin obviously doesn't see it that way, the trick of the charlatans and scammers? Is this a trick? If this was also called a trick, Li Shimin would not have been haunted by nightmares for so long.

At least Li Chunfeng, who is one of the leaders of the Daomen today, can't come to these hands. In terms of pretending to be a god and playing ghosts, who else is better at it than Daomen?

Li Shimin asked noncommittally: "Oh, the two generals of mine, what did they fight with in the middle of the night last night?" Zhang Zheng arched his hand and replied: "Nothing, Weichen just let the two uncles slash at the air for half the night." ”

"To the air?" Li Shimin was stunned, last night through the shadow of the lamp, he clearly saw that the two generals, Wei Chigong and Qin Qiong, blocked tens of millions of Yin soldiers for him.

"This is a science, and Wechen calls it psychology. Your Majesty can simply understand that Weichen used some means to release the fear in His Majesty's heart. As for the two old generals, they are just an auxiliary means, and it is His Majesty himself who really defeats fear. Zhang Zheng explained in a timely manner, and didn't say much, because Li Shimin couldn't understand it if he said too much.

"......I see," Li Shimin muttered to himself, and then pondered.

"Actually, what Your Majesty wants to ask is about ghosts and gods." Without waiting for Li Shimin to speak, Zhang Zheng broke Li Shimin's mind with one word.

Li Shimin looked back at Zhang Zheng in surprise when he heard this, and simply stopped pretending. Zhao Zhang Zheng said seriously: "Yes, I am indeed very curious about the matter of ghosts and gods. Prudence may solve my doubts? Zhang Zheng chuckled in his heart, it seems that he really scared Li Shimin last night.

Otherwise, with Li Shimin's pride, why bother to find a teenager to solve his doubts. However, Zhang Zheng's purpose was just to scare Li Shimin and let out the evil anger in his heart.

Rather than really turning Li Shimin into feudal superstition. An emperor is still an emperor of the people, and it is better to serve the people.

To serve the ghosts, once in a while will do. So Zhang Zheng suddenly talked about something that happened in the Western Han Dynasty.

"In the past, Emperor Taizongwen, after sacrificing to the ghosts and gods, summoned Jia Yi in the middle of the night to ask about the ghosts and gods, how similar is it to today, what does Your Majesty think?" Except in time and form, it is indeed very similar.

In terms of time, one is in the middle of the night and the other is at noon. And formally, one is just after sacrificing to the ghosts and gods, and the other is just getting rid of the nightmare of the ghosts and gods.

"This, what does this matter have to do with me?" Zhang Zheng's words came out, and Li Shimin was directly stunned.

Li Shimin naturally read the book of historical records I don't know how many times. "Historical Records: The Biography of Qu Yuan Jia Sheng" contains: "Jia Sheng is recruited. Emperor Xiaowen received the award and sat in the Xuan room. Because of the feeling of ghosts and gods, he asked about the origin of ghosts and gods. Jia Sheng is so natural because of the Tao. In the middle of the night, Emperor Wen sat in front of him. After that, he said: "I haven't seen Jia Sheng for a long time, I think it's too much, and now it's too late, so Li Shimin naturally knows about this matter, but what is the connection between the two?" Is there anything in it that I don't know? Zhang Zheng stood with his head held high, and replied without humility or arrogance: "It doesn't matter, the minister just wants to ask Your Majesty, don't ask the common people to ask the ghosts and gods, why not?" ”

"Don't ask the common people, ask the ghosts and gods." Li Shimin naturally didn't know this allusion, after all, the ancestors of Li Shangyin, the original author of this poem, still don't know where to go.

But it did not affect Li Shimin in the slightest to feel the meaning of Zhang Zheng's exhortation. And Zhang Zheng, throwing out this allusion, naturally has a deep meaning.

Li Shimin in history, because of his superstitious belief in ghosts and gods, wanted to live forever, and he hiccups himself in his fifties.

It is also a good thing for him to know about the ghosts and gods as soon as possible and to focus on governing the country. Moreover, Zhang Zheng's knowledge has to be valued by Li Shimin.

Now that the academy was founded, Zhang Zheng did not make drastic reforms, and used the academy to spread the knowledge of the previous life.

Instead, these learnings were taught to Li Tai alone. First, the foundation of the academy is too thin, and the basic knowledge of the students of the academy is uneven, and it is simply impossible to reach the foundation for disseminating these knowledge.

Second, it is also because of Li Shimin that the emergence of any kind of new learning cannot become a mainstream doctrine without the support of the rulers of the current dynasty.

Even if it is short-lived among the crowd, it is only a flash in the pan. Confucianism and other schools of thought among the hundred schools of thought are the best examples.

Today's hundred schools of thought, Confucianism, because of the support of Emperor Wu at the beginning, developed to the Tang Dynasty, has become the pinnacle of ideological and academic doctrine.

Most of the other homes have been dissipated in the long river of history. Even the law, soldiers, vertical and horizontal, and the Mo family who were arrested by Zhang Zheng are still alive.

It is said that the inheritance has not been broken, but in fact, it can only be attached to the tail wing of Confucianism. Only in this way can the legacy be maintained.

Zhang Zheng's learning in his previous life was not the study of governing the country, but the study of the world. Governing the country with Confucianism and learning from the world with new learning is the main purpose of Zhang Zheng's establishment of the academy.

Rather than categorizing this thing in Confucian tricks. To put it simply, civilize its spirit, barbarize its body.

What Zhang Zheng needs is that his knowledge can keep pace with Confucianism.

"Don't ask the common people, ask the ghosts and gods." Li Shimin muttered to himself, his face becoming serious. Suddenly, he arched his hand at Zhang Zhengyi: "It's my face." "Zhang Zheng's favorite thing is Li Shimin, and he can listen to persuasion.

So Zhang Zheng did not avoid Li Shimin's gift. After receiving a salute from Li Shimin, Shengsheng said: "Recently, the minister has been teaching Qingque several new knowledge, one is arithmetic, the second is chemistry, and the third is Gewu. The psychology that His Majesty mentioned just now, Wei Chen will also teach Qingque in the near future. Arithmetic, together with physics, is the basis of chemistry and physics. Chemistry is a discipline that can explain the structure of all things in the world. For example, gunpowder, which is just a combination of three simplest and most common substances, why can such a violent reaction occur? And last night's alkaline water reacted with ginger water, why does it appear red? Gewu is a science that can explain the laws of the operation of all things in the world. Taking the Quyuan plough as an example, Wechen only made a small change to the straight plow, why can it more than double the efficiency of cultivated land? These are all the academic domains of the minister. The sun rises in the east and sets in the west, the seasons alternate, and the yin and yang gods change day and night...... Whether there are ghosts and gods in the world is not known, at least not before. But for other things, Your Majesty can ask the ministers, or you can ask the green sparrow. ”

"Arithmetic, Chemistry, Physics, Psychology?" Li Shimin nodded, and after listening to Zhang Zheng's tirade, he looked unclear.

Then he smiled and asked, "Is this your knowledge?" ”

"Yes, this is only part of the courtier's knowledge, but there are also geography, biology and so on. The ministers will slowly teach it to the green sparrows. ”
