That’s not right!

Fusu scratched his head.

Young men like them all need to be able to swim. Even though Hu Hai is a young boy, he is still very talented in swimming. His favorite thing every summer is to get into the pool and swim back and forth for several times without losing breath. Why did he fall into the river like this?

Drowned in?

"Well... I didn't drown."

Han Xin waved his hands awkwardly.

"Can you finish the sentence in one go?"

"I just saw him fall into the river, so I quickly got into the water. But he swam faster than me and I couldn't catch him."

"Then why are you panicking?"

Cao Xiu rolled his eyes.

These days, people in Guizhou who live near the water can basically swim. Especially in the summer, everyone dives into the water, so children drown every year. Later, Cao Xiu came forward and said that there was a water ghost in the water.

Only by catching a substitute can I get free. It has only gotten better in the past two years. Even if I play in the water, it is only in the shallow water area.

"The main thing is that he seems to have changed..."

"???"

"He ignored me and just sat on the shore laughing."

"..."

Cao Xiu was stunned.

Is it possible that he is also possessed by a time traveler?

Wrong!

He was not even drowned, which obviously did not comply with the first law of time travel!

"Hahahaha!"

Hu Hai's hearty laughter came from outside.

I saw him walking towards me carrying a fishing rod.

"How can I say that I have no clothes? I share the same robe with you. When the king raised an army, he repaired my sword and spear. I share the same enemy with you!"

"Xiu'er, come out quickly!"

"I fixed all your fishing rods!"

"..."

Qin Shihuang frowned, and an unknown fire surged into his heart. Seeing Hu Hai's drowned appearance, he already knew what was going on. Cao Xiu was just fooling around, and Hu Hai was also fooling around, one dared to teach and the other dared to learn!
p>

Hu Hai whistled loudly, and he successfully repaired the automatic fishing device. Originally, he still had a headache, maybe because of the hot weather. When he fell into the river, he suddenly woke up and thought of a way to repair the fishing device.

Facts have proved that he is a genius!

He didn't even ask for the teacher, he did it easily. Not only that, he actually caught an old turtle. It's a pity that he didn't catch the turtle, otherwise he would have killed the turtle in seconds with a slide shovel.

"Xiu'er, how about taking a look at my turtle?"

"..."

Cao Xiu breathed a long sigh of relief and said with a wry smile: "Xiao Zhu, you may have just come to Peixian County and you don't know many things. You have repaired your fishing equipment very well. It is not easy to do this. But... you can just repair the fishing rod.

Repair the fishing rod, why jump into the river?"

"What are you afraid of? I know how to swim!"

Hu Hai waved his hand nonchalantly.

"Let me tell you, there are water ghosts in our river. They look for a substitute every year. Even if you know how to swim again, it will be useless. If you are caught, you will die. There used to be a child about your age, who was also good at water. Now

Almost two years old.

Water...water ghost?!

Even though Hu Hai is so old, he is quite afraid of the dark and ghosts because of the shadow of his childhood. After hearing what Cao Xiu said, he immediately shrank back in fear.

"It's also because I'm hot..."

"This is your fault." Fusu clasped his hands behind his back and said seriously: "Mencius once said: When heaven assigns a great responsibility to a person, he must first strain his mind, strain his muscles and bones, starve his body and skin, and deplete his body. This is

If you can't stand even a little heat, how can you achieve great things in the future?"

"Stop, silence!"

Cao Xiu couldn't help but raise her hand.

This guy is really awesome!

In his view, it seems that hard work is a matter of course. Hard work is certainly worthy of praise, but it is not what it should be. Why not enjoy it if you can enjoy it?

Then, Cao Xiu looked at Hu Hai.

"Little Pig, I will take you to play something fun again."

"What?"

"Use hot water to make ice."

"Uh?!"

Not to mention Hu Hai, even Qin Shihuang and others were shocked.

Fu Su was even more surprised, "Liezi once recorded that Lao Chengzi learned from Mr. Yin Wen, and he had the ability to thunder in winter and make ice in summer; those who fly can walk, and those who walk can fly. Is it possible that Mr. Cao also has this ability?"
p>

"Ahem, it's a bit far behind."

Cao Xiu smiled helplessly.

In the eyes of the ancient people in the pre-Qin Dynasty, making ice in the summer was a legendary magical method. In fact, a hundred years later, the ancients did it. Of course, it was not making ice with saltpeter. The tricks people played were quite sophisticated, but it was made with hot water.

Ice. It means: take the boiling soup and put it in an urn, seal it with a new seal, and let it turn into ice in three days.

Later generations of scientists have conducted experiments many times, proving that the theory is correct, but the actual operation is extremely demanding. To put it more simply and understandably, it is probably the rapid cooling of gas after adiabatic expansion, which is the Joule-Thomson effect.

Cao Xiu also tried many times, but most of them ended in failure. He happened to be bored, so he thought of trying again with Li Hai.

As for making ice with saltpeter?

Can this method of making money be revealed easily?

It’s okay for others, but not Li Hai.

……

……

At night.

Cao'er brought the boiling water over, using a specially made clay pot. The mouth was small and the belly was big, and it was still steaming. After seeing that the time was almost up, he immediately soaked the water with fine silk, and then blocked the pouring mouth tightly.

After tying the rope to the pot, sink it directly into the deep well.

This well is about three feet deep, which is relatively deep. After two or three days, the pot will freeze inside, which is the legendary deep well ice.

"That's it?"

Qin Shihuang stood on tiptoe with a puzzled look on his face.

The art of making ice in summer is only legendary and has never been seen by anyone. For example, there is a special Lingren in their palace who is responsible for keeping ice. Every winter when it is the coldest, ice cubes will be stored in the ice cellar.

When leaving, the door will be blocked with cloth. When the summer is hot, the ice will be taken out and used.

However, doing this will probably result in a loss of about half. Therefore, most people cannot enjoy it at all, only the top few can enjoy it. Let’s take Peixian County, Xiao He has some ice cubes in his house, and he

It’s not enough, let alone giving it to others.

"Don't worry, you will know in three days."

"Is your well any different?" Hu Hai scratched his head and asked in confusion: "Why does it freeze when you put boiled water in it and take it out three days later?"

"Never played it before, right?"

"Never played..."

"Is it fun?"

"Fun!"

Cao Xiumei smiled brightly, "This is all knowledge. Even if you are playing, you have to come up with new tricks. This is called ability. If you can't even understand how to play, then you are pure waste."
p>

"Okay, I will definitely understand!"

"..."

"..."

Qin Shihuang opened his mouth and was speechless for a long time.

He was thinking, how about sending Hu Hai back? He thought that Cao Xiu would do his best to teach Hu Hai well. But now it seems that this has directly led Hu Hai astray!

Moreover, Cao Xiu feels pretty good about herself.

He felt that by doing this, both sides could make it through. Li Si couldn't find fault with him, and Azheng, the rebel, would be satisfied. After all, he didn't teach him any real skills.

There is no way, it is difficult to be a rebel!

It’s even harder to be a rebel like him!
