Li Zhi, don't be a coward

Chapter 272

The advantage of the traveler is that the knowledge beyond the millennium can often create many miracles, and such miracles are as incredible as miracles in the eyes of the ancients.

Hearing that Li Qinzai was going to do a trick, Qiao'er, who was in high spirits, came out of the yard and yelled a few times, and the news spread immediately.

Everyone in Zhuangzi knows that Li Qinzai's tricks are absolutely shocking miracles. The little bastards and the farmers still remember the cannonball made by Li Qinzai years ago. People still say it proudly.

Today I heard that Li Qinzai was going to perform a trick again. After the news spread, Li Sujie and a group of dudes in the school at the southern end of Zhuangzi rushed towards the other courtyard.

The Guozijian students who didn't know the truth saw the dandies run away, they didn't care and ran after them, anyway, they would grab the dandies even if it was shit.

Outside the Li family courtyard, the crowd quickly surrounded the inner three floors and the outer three floors.

Li Zhi in the backyard was also startled, and immediately ran out of the gate. Wang Changfu made a sharp voice, and the students were startled, and they all took a few steps back and bowed.

Li Zhi easily occupied a best viewing position, crossed his hands on his abdomen, and the small theater waited for Li Qinzai to start with a smile like a cross talk.

Li Qinzai is undoubtedly the most beautiful boy in the crowd. Seeing the dense crowd around him, Li Qinzai twitched his cheeks a few times, and smiled bitterly: "I just made something new, you don't have to do this, I will tell you the principle later, this is also part of Gewuxue ..."

Li Zhi smiled and said: "Jingchu's new gadget, which one is not shocking? Let's start, I have been waiting for a long time."

Li Qinzai had no choice but to turn around and order Liu Ah Si to find a big wooden barrel, a copper basin, and a few catties of saltpeter.

Saltpeter is the raw material for making gunpowder. When Li Qinzai made firecrackers, there was a lot left at home.

Fill the barrel with half of the water, and then throw saltpeter into it, the water in the barrel reacted instantly, gurgling as if boiling.

The copper basin filled with drinking water floated on the surface of the water in the wooden bucket with both hands, fixed still.

Everyone gathered around curiously, staring at the barrel without blinking.

Soon, an incredible scene happened. The water in the barrel froze quickly visible to the naked eye, and the clear water quickly turned into translucent ice cubes. The drinking water in the copper basin on the surface of the barrel also Freezes quickly.

I don't know who took the lead to let out a horrified scream, and the crowd immediately exploded.

In the hot summer, witnessing that a little bit of water turns into ice is not only a miracle, it is a magic.

Li Sujie blushed, stretched out his finger to touch the ice surface in the wooden bucket resolutely, and then quickly retracted, the veins on his neck throbbed violently, and shouted: "It's ice! It's really ice! Mr. Turned into ice!"

Li Qinzai's old face darkened, ignoring Li Sujie's own father who was at the side, he reached out and slammed Li Sujie's head hard: "Idiots without skills! The unexplainable phenomena in the world are said to be immortals. What else do you need to learn?"

Li Zhi on the side was stunned for a long time, and said in a stuttering manner: "Could it be because of Jing Chu's knowledge?"

Although it is very similar to Li Sujie's stupid appearance, Li Qinzai did not dare to knock Li Zhi's head, so he had to say: "Yes, everything in the world can change. If you know its laws and make it react with other things, everything can change hundreds of thousands of times." Things, millions of things."

"This is another subject of my science. It's called 'chemistry'. As the name suggests, it is the study of the transformation of all things. The gunpowder I created is also a part of chemistry."

Li Zhi reached into the bucket, felt the bone-chilling cold with his fingertips, tapped the ice cubes with his fingers, took a deep breath, and sighed: "Jing Chu's talent always surprises me every time, astonishes me as a heavenly man."

Li Qinzai smiled, and ordered someone to bring an iron spoon, knocked on the ice in the copper basin for a while, knocked off a small piece of ice, and stuffed it into Qiao'er's mouth.

Qiao'er had ice cubes in his mouth, and a cool and refreshing feeling spread from his mouth to his abdomen, and he immediately smiled in comfort.

Li Qinzai smiled and said: "Ice can relieve the heat, but it should not be too much, or it will cause stomach upset."

Qiao'er nodded, but still greedily licked the ice in his mouth.

Li Zhi also took a piece of ice and put it in his mouth, humming comfortably, the students next to him rushed up, each took a piece of ice, Zhu Bajie swallowed it like eating ginseng fruit.

After chewing a few pieces of ice, Li Zhi looked at Qiao'er happily sipping ice cubes, and Li Qinzai's doting eyes, Li Zhi suddenly thought about it.

"I was short of ice cubes when I drank grape wine with you today, why didn't you make them at that time? Qiao'er thinks that the weather is hot, and your ice cubes came into being. Jingchu, what do you mean?"

Li Qinzai was startled, and without blinking his eyes, he said: "The Lord is worried about the humiliation of the minister. It is because of the lack of ice cubes for your majesty's fine wine that you have worked so hard to study it. It took you a whole afternoon to come up with the method. Your majesty must not misunderstand it."

Li Zhi said with a half-smile, "Isn't it because Qiao'er is too hot?"

"Of course not, this is a wish from the minister to His Majesty."

Li Zhi snorted, and said, "I'll just pretend to believe you...with ice cubes, I can drink grape wine to my heart's content."

Li Qinzai said seriously: "Your Majesty, don't forget your old illness. This illness is not suitable for drinking alcohol or meat. Your Majesty has not suffered from illness for more than half a year. If all previous efforts are wasted because of the contents of this cup, wouldn't it hurt the country of the Tang Dynasty?" Guoben?"

Li Zhi was startled, then sighed with a wry smile: "Jingchu, you are such a disappointment!"

Although disappointed, Li Zhi still listened to Li Qinzai's words, hummed resentfully, knocked a large piece of ice out of the copper basin, held it in his hand and went back to the backyard while sipping.

After Li Zhi left, Li Qinzai looked around at the students and said: "The way of calculating is not just about addition, subtraction, multiplication and division, or just getting the answer to a certain question. For the world, simplify the process of people's basic necessities of life."

Li Qinzai picked up a piece of ice and said slowly, "use the knowledge you have learned to create things that ordinary people dare not even imagine. This is the true destination of knowledge."

Li Sujie and others saluted solemnly: "Thank you sir for your clear instruction, my disciple has been taught."

Li Qinzai said again: "The process of turning water into ice is very simple, but the principle is very complicated. There is a laboratory in the school, and its function is to often do some similar small experiments. But right now, you still need to learn how to calculate clearly. Only after the completion can we slowly come into contact with more esoteric physics and chemistry."

All the students should salute.

Behind the gate of the other courtyard, Li Zhi stood quietly behind the gate and listened to Li Qinzai's lecture.

After a long time, the corner of Li Zhi's mouth twitched, and he murmured: "Turning water into ice... is undoubtedly a disciple of the Mohist school. The world is blessed with the Tang Dynasty."
