Zhu Shun stood up and walked to the side of the red sandalwood bookcase, picked up the iron and said, "Does the prince believe that the prince can turn this basin of water green." ”

The crown prince Zhu Cihong learned from his mother about the incident of Jinshi Weikai a month ago, but he heard that the iron disappeared, and he couldn't see it with his own eyes, and he didn't know that it would turn light green.

The crown prince Zhu Cihong looked at him curiously and did not speak.

Arousing the prince's curiosity, Zhu Shun picked up the iron and put it into the dilute sulfuric acid.

Iron is replaced with dilute sulfuric acid, and a large amount of hydrogen is displaced.

The crown prince Zhu Cihong's eyes immediately widened, his expression was the same as those Donglin Party officials, and he looked at the basin of clear water in a daze, and the clear water was boiling without the burning of the charcoal fire.

After boiling, the clear water is like getting an immortal magic like turning stones into gold, and it really turns green.

Zhu Shun glanced at the wide-eyed prince, smiled, and picked up a piece of tin: "The next basin of water, for the teacher, I want to turn it yellow." ”

The man of the iron tower brought another basin of water, and Zhu Shun threw the tin into the water.

The metal activity of tin is also in front of hydrogen, and the displacement reaction between tin and dilute sulfuric acid releases hydrogen gas and produces stannous sulfate.

A basin of clear water turned pale yellow in the eyes of the crown prince Zhu Cihong's widening eyes.

Before it was over, Zhu Shun continued to ask the tower man to bring a basin of water and a stone, picked up the stone and put it in the hands of the prince Zhu Cihong, so that he had a sense of participation: "Prince, what is this." ”

The crown prince Zhu Cihong saw the first two immortal techniques with his own eyes, and thought that it was some kind of fairy treasure, so he carefully held it in his hand, looked back and forth for a long time, and asked hesitantly: "Sir, is this a stone?" ”

Zhu Shun smiled and nodded: "That's right, this is the stone, do you think the water can crack the stone." ”

The crown prince Zhu Cihong subconsciously shook his head, the water is the softest, the stone is the most rigid, how can the softest water crack the stiff stone, and it is not a sledgehammer.

Unless it is an immortal technique, thinking of Zhu Shun's first two immortal techniques, the crown prince Zhu Cihong nodded again.

Zhu Shun saw that the prince shook his head and nodded, knowing his thoughts, and said with a smile: "You throw the stones into the basin yourself." ”

The crown prince Zhu Cihong glanced at Zhu Shun in puzzlement, saw that his husband's face was calm, walked over lightly, and threw the stone in his hand into the clear water.

Calcium and dilute sulfuric acid can also undergo a displacement reaction, and a large amount of hydrogen gas is produced.

The crown prince Zhu Cihong was obviously frightened by the boiling water out of thin air, and he ran faster than a rabbit at once, and there was no longer the slightest pedantic spirit of following the rules, and he rushed behind Zhu Shun.

After a few breaths, the crown prince Zhu Cihong poked out half of his head and said in shock: "Sir, Lone can also use immortal arts?" ”

Zhu Shun sat back on the official hat chair in the main hall and said with a gentle smile: "This is not immortal art, this is called science, and it is an academic that can change the world." ”

"The several phenomena that the prince just saw are all displacement reactions in science, which are displacement reactions caused by iron, tin, calcium and dilute sulfuric acid."

The crown prince Zhu Cihong didn't understand any new words such as science, displacement reaction, and dilute sulfuric acid, but he was very interested in the immortal art in front of him.

opened his mouth to speak, closed it again, opened his mouth again, and went back and forth three or four times, and the crown prince Zhu Cihong said with a smile: "Sir, can you go back and show it to the queen mother." ”

If this was replaced by seven disciples, Zhu Shun would have reached out to rub the disciple's head at this time, but this was the prince in front of him, and there were several eunuchs from Dongchang standing at the door.

Although Wang Chengen, the governor of Dongchang, is Zhu Shun's close friend, it is better to commit fewer crimes in his transgressive behavior, so as not to leave any handle for the Donglin Party that is angry and corrupts Zhu Shun's heart.

Zhu Shun continued to smile gently: "This basin of water is not ordinary water, it is called dilute sulfuric acid, and later the teacher will let Miao'er go with you and help you prepare dilute sulfuric acid according to a certain proportion." ”

Prince Zhu Cihong's unsmiling little face had a hint of innocence that a child should have: "Thank you, sir." ”

Then he took a deep breath and said solemnly: "Sir, let's learn "Zhuzi" or "Recent Thoughts" next." ”

The crown prince Zhu Cihong has been forced by his mother to recite a lot of subsets of scriptures and histories over the years, and he has become tired of it for a long time, and every time he recites it, it is like a punishment, and he is miserable.

This time, the crown prince Zhu Cihong had already inquired, and the old-fashioned gentleman would teach more subsets of scripture and history, and if he didn't learn well, he would play the board.

The crown prince Zhu Cihong is ready to go up the knife mountain and go down to the sea of fire, and he has also thought of a way to deal with it, that is, to be a wooden man, and what the gentleman says.

It is extremely rare to be able to take the initiative to say what to learn.

Zhu Shun didn't know the careful thinking of the crown prince Zhu Cihong, waved his hand and said, "That's all for today's experimental class, the prince should go back and rest." ”

It took a lot of courage for the crown prince Zhu Cihong to take the initiative to say that sentence, but it turned out to make his eyes wider.

Gone?

The crown prince Zhu Cihong was afraid that his husband would regret it, so he was stunned and quickly left here, and fled here at a trot regardless of his demeanor.

Zhu Shun looked at the crown prince Zhu Cihong, who had fled from here, and basically figured out the mind of this noble disciple of Tianhuang, tired of the boring Cheng Zhu Lixue, and preferred novel experimental classes.

Zhu Shun explained to the man of the iron tower, asked him to call Jiao Miao, and left here to go to the workers' hall.

Forbidden City, Harem.

There is a shuttle loom in the gold brick hall, and Queen Zhou is weaving new winter clothes for the emperor, when she suddenly heard the sound of trotting outside the hall, frowning slightly, this new little eunuch and palace maid are inevitably a little rude.

Before Empress Zhou could speak, she saw the emperor, who had always looked like a primary school, and ran in happily.

is not unorthodox, but she is also like a child for the first time in front of her mother.

Empress Zhou is still a mother after all, and said with a smile: "Slow down, don't fall." ”

The crown prince Zhu Cihong ran to the queen mother's side, only then did he think that his behavior just now was really unruly, and he didn't care, holding an iron block in one hand and a tin block in the other, and said as if offering a treasure: "Queen mother, the child can make the water change color." ”

"Jiao Qiao, hurry up, hurry up and make a basin of that kind of sour water."

When Empress Zhou heard the emperor's shout, she noticed that the emperor was followed by a young man wearing a wide right coat, and she couldn't help but feel a little distressed.

This child is also too thin, thin and small, and it looks like he hasn't eaten anything good since he was a child.

Queen Zhou's voice softened a lot, and she instructed: "Go and bring a box of lotus cakes handmade by the palace and give it to this child to take away." ”
