its not right!
Fusu scratched his head.
Young men like them all have to know how to swim. Even though Hu Hai is a young boy, he is still very talented in swimming. My favorite thing every summer is to get into the pool and swim back and forth for several times without taking a breath. Why did I just fall into the river and drown?
"Well...not drowned."
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 and he had to catch a substitute to free him. Things have gotten better in the past two years. Even if they play in the water, it is only in the shallow water area.
"The main thing is that he seems to have changed as a person..."
"???"
"He ignored me and just sat on the shore laughing."
"..."
Cao Xiu was stunned.
Could it be that he is also possessed by a time traveler?
wrong!
He wasn't even submerged, which obviously didn't comply with the first law of time travel!
"Ha ha ha ha!"
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. The king raised an army and repaired my 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 messing around, Hu Hai was also messing around, one dared to teach and the other dared to learn!
Hu Hai whistled loudly as 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!
You don’t even need a teacher, it’s easy to do. Not only that, he actually caught an old turtle. It's a pity that he didn't catch the turtle, otherwise he would kill the turtle in seconds with a sliding 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, and it is not easy to do this. But... you can 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, shut up!"
Cao Xiu couldn't help but raise his hand.
This guy is so awesome!
In his opinion, 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. If you can enjoy it, why not enjoy it?
Then, Cao Xiu looked at Hu Hai.
"Little Pig, let me play something fun with you again."
"What?"
"Use hot water to make ice."
"Forehead?!"
Not to mention 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, 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?"
"Ahem, it's a bit far."
Cao Xiu smiled helplessly.
In the eyes of the ancient pre-Qin people, Xia Zaobing was a legendary immortal magic. In fact, a hundred years later, some ancient people accomplished it. Of course, ice is not made from saltpeter, as the tricks used by people are quite sophisticated, but ice is made from hot water. 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 also conducted many experiments, proving that the theory was fine, but the actual operation was extremely harsh. To put it simply, 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 it again with Li Hai.
As for making ice from saltpeter?
Can this method of making money be easily disclosed?
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 is small and the belly is big, and it is still steaming. After checking that the time is almost up, immediately soak the water with fine silk, and then block the mouth of the mouth tightly. Then tie the rope to the clay pot and sink it directly into the deep well.
This well is about three feet deep, which is considered relatively deep. After waiting for two or three days, ice will form inside the clay pot, which is the legendary deep well ice.
"That's it?"
Qin Shihuang stood on tiptoe, looking puzzled.
Xia's ice-making technique is only legendary, and no one has ever seen it. For example, there is a special Lingren in their palace who is in charge of ice matters. During the coldest winter every year, ice cubes are stored in the ice cellar, and the door is blocked with cloth before leaving. When it gets hot in the summer, the ice will be taken out and used.
However, doing so will probably result in a loss of about half. Therefore, the vast majority of people cannot enjoy it at all, only the top elites can enjoy it. Let's just talk about Peixian County. Xiao He's house has some ice cubes, which are not enough for himself, let alone for others.
"Don't be anxious, we 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?"
"You haven't played before, have you?"
"never play it……"
"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."
"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? I thought that Cao Xiu could devote all his efforts 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 so, both sides could make sense. Li Si couldn't find fault with him, and Azheng, a traitor, 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!
