That's not right!

Fusu scratched his head.

Sons like them have to be able to swim. Don't look at Hu Hai as a young son, his swimming talent is still very high. Every summer, my favorite thing is to drill into the pool, swim a few back and forth without panting, why did I just fall into the river and drown?

"Uh...... Not drowned. ”

Han Xin waved his hand awkwardly.

"Can you finish it all at once?"

"As soon as I saw him fall into the river, I hurried into the water. As a result, he swam faster than me, and he couldn't catch it. ”

"Then what are you panicking about?"

Cao Xiu rolled her eyes.

Qianshou, who was born near the water in this year, can basically swim. Especially in the summer, everyone is drilling into the water, so there are drowned children every year. Later, Cao Xiu came forward and said that there were water ghosts in the water who had to catch a stand-in to get free, and it was only slightly better in the past two years. Even if you play in the water, it's only in the shallow water.

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

“？？？”

"I told him to ignore me, and he sat on the shore and laughed."

“……”

Cao Xiu was stunned for a moment.

Could it be that he was also possessed by the traverser?

Wrong!

He didn't even drown, obviously not in line with the first law of crossing!

"Hahahaha!"

Hu Hai's hearty laughter came from outside.

And he came with a fishing rod on his back.

"Do you say you have no clothes? with the Son. Wang Yuxingshi, repair my spear. Enmity with the Son! ”

"Xiu'er, come out quickly!"

"I've fixed all your fishing rods!"

“……”

Qin Shi Huang frowned, and a nameless fire surged into his heart. Seeing Hu Hai's appearance as a soup chicken, he already knew what was going on. Cao Xiu is just messing around, and Hu Hai is also messing around, one dares to teach and the other dares to learn!

Hu Hai whistled, and he successfully repaired the automatic fishing machine. Originally, he still had a headache, perhaps because of the hot weather, but when he fell into the river, he instantly sobered up, and he also thought of a way to repair the fishing gear.

As it turned out, he was a genius!

I didn't even ask for a teacher, so I could do it easily. Not only that, but he also really caught an old turtle. It's a pity that he didn't catch the ray, otherwise he would have given the ray seconds with a sliding shovel.

"Xiu'er, how about my turtle?"

“……”

Cao Xiu breathed a long sigh of relief and said with a wry smile: "Little pig, you may have just come to Pei County, and you don't know a lot of things. Your fishing gear is very well repaired, and it's not easy to do it to this extent. But...... If you repair a fishing rod, you will repair a fishing rod, what will you jump into the river? ”

"What are you afraid of, I know water!"

Hu Hai waved his hand nonchalantly.

"I tell you, there are water spirits in our river. Every year, you will find a stand-in, even if you know how to water again, it is useless, and if you are caught, you will die. There used to be a child about the same age as you and very good at water, but now he is almost two years old.

Water...... Kelpie?!

Don't look at Hu Hai is so old, but because of the shadow of his childhood, he is quite afraid of the dark and is also afraid of ghosts. After hearing Cao Xiu say this, he suddenly shrank his neck back.

"I'm also ...... because of the heat"

"That's yours, isn't it." Fusu put his hands behind his back and said seriously: "Mencius once said: When the heavens descend on the people, they must first suffer their minds, strain their muscles and bones, starve their bodies and skin, and empty their bodies. I can't stand this little heat, how can I become a big thing in the future? ”

"Stop, shut up!"

Cao Xiu couldn't help but raise her hand.

This guy is so good!

In his opinion, it seems that hardship and hard work are taken for granted. Hardship and hard work are certainly worthy of praise, but it is not the way it should be, so why not enjoy it if you can enjoy it?

Then, Cao Xiu looked at Hu Hai.

"Little piggy, I'll take you to have a fun time."

"What?"

"Ice is made with hot water."

"Huh?!"

Don't say Hu Hai, even Qin Shihuang and others were shocked.

Fusu was even more surprised, "Liezi once recorded that Lao Chengzi learned from Mr. Yin Wen, there was thunder in winter and ice in summer; The flyer walks, and the walker flies. Could it be that Cao Jun also has this ability? ”

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

Cao Xiu smiled helplessly.

In the eyes of the pre-Qin ancients, Xia Zaobing was the legendary immortal law. In fact, a hundred years later, some ancients did it. Of course, it is not saltpeter to make ice, and the routine played by people is quite sophisticated, but to make ice with hot water. It is said: take the boiling soup and put it in the urn, dense it with new threads, and Shen Zhong will become ice in three days.

Later generations of scientists have also done many experiments to prove that the theory is fine, but the actual operation is extremely harsh. To put it in layman's terms, it is probably the rapid cooling of the gas after adiabatic expansion, which is the Joule-Thomson effect.

Cao Xiu also tried many times, mostly in failure. happened to be idle and bored, so he thought about taking Li Hai to try again.

As for saltpeter ice?

Can this method of making money be easily revealed?

Forget about others, but Li Hai can't.

……

……

Night.

Cao'er brought the boiling water, and the clay pot used was also specially made. The mouth is small and the belly is big, and it is still steaming. After seeing that the time was almost there, he immediately soaked it in water with fine silk silk, and then blocked the irrigation mouth. After tying the clay pot with ropes, it sinks directly into the deep well.

This well is about three zhang deep, which is relatively deep. After waiting for two or three days, the inside of the clay pot will freeze, which is the legendary deep well ice.

"That's it?"

Qin Shi Huang stood on tiptoe, his face full of puzzlement.

The technique of making ice in Xia is only legendary, and no one has ever seen it. Like they have a special Ling person in the palace, who is in charge of the matter of ice. Every year when the winter is the coldest, the ice is stored in the ice cellar, and the door is blocked with a cloth when leaving. When it is hot in the summer, the ice is removed and used.

However, you will lose about half of what you do. Therefore, the vast majority of people can't enjoy it at all, only the top vote is available. Let's just talk about Pei County, and Xiao He's family has some ice cubes, and he doesn't have enough for himself, let alone for others.

"Don't worry, I'll know in three days."

"Is there any difference between your well?" Hu Hai scratched his head and said incredulously: "Why do you put boiling water in it and take it out after three days to freeze?" ”

"Haven't you played it?"

"Haven't played ......"

"Fun, right?"

"It's fun!"

Cao Xiu's eyebrows danced and smiled, "It's all about knowledge here." Even if you play, you have to play new tricks, which is called ability. If you can't even play it, it's pure waste. ”

"Okay, I'll figure it out!"

“……”

“……”

Qin Shi Huang opened his mouth and couldn't speak for a long time.

He was thinking, why don't you send Hu Hai back? I 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.

He felt that by doing so, he could talk about it at both ends. Li Si can't find fault with him, and Ah Zheng, the thief, will be satisfied, after all, he didn't teach some real skills.

No way, it's hard to be a thief!

It's even harder to be a thief like him!
