Gou in Daming, I was overheard by Zhu Yuanzhang

Xu Huaijin's horse was brought from Jiayuguan. This horse is white all over, and Xu Huaijin likes it very much.

It can be said that apart from the fact that he has had contact with him, this horse has been with him the most.

Now, in order for the entire Ming army to cross the lake as soon as possible and reach the other side before the Hu people, the horse couldn't care less.

As a military division and a member of the army, you must set an example everywhere.

Since all horses and camels don't use pumice stones, your own horses can't be special either.

Looking at Ma'er's eyes, he seemed to understand what was going to happen next, and Xu Huaijin suddenly broke his defense.

Tears flowed down my face.

Xu Huaijin hugged the horse's neck tightly, and the white horse also rubbed against Xu Huaijin.

"Xu Huaijin, what's wrong with you? This horse also has altitude sickness?" Zhu Yunxie asked strangely.

Xu Huaijin put away her tears, but her eyes were still red.

"Crying? Like a rabbit's eyes!" Zhu Yunxi said, "Hurry up, tie up the pumice stones and get ready to cross the lake!"

"My horse," Xu Huaijin said, "can I not cross the river? Just let it go."

Xu Huaijin thought to himself, letting the white horse leave by itself, go down the mountain, and return to the grassland is better than forcibly crossing the water.

"Xu Huaijin, you don't want a horse anymore? On the other side, what should you do if you don't have a horse?" Zhu Yunxie smiled and said, "Do you want me to hold you and let the horse go away on purpose?"

Xu Huaijin was ashamed and angry: "Deng Tuzi!"

"Let the horses enter the lake, I am afraid that few horses will be able to swim to the other side alive!" Xu Huaijin said: "God has the virtue of good life, and horses have spirituality."

"Xu Huaijin, what are you talking about, few horses can swim to the other side alive?"

Zhu Yunxi smiled and said, "Don't worry, no horse will die!"

Xu Huaijin doesn't know whether he should believe Zhu Yunxi's words at all now. He speaks now, one sentence is true, one sentence is false, true and false, it is not clear which sentence is true and which is false!
"King Wu, didn't you just say that a horse can swim, but not too far! A camel can also swim, but it can last a shorter distance than a horse!"

"Look at the lake, how long will it take to go to the opposite side? Which horse will last?"

Zhu Yunxi slapped his head: "Hey, I forgot. I forgot to tell you, I told everyone."

"Xu Huaijin, I will do an experiment for you. Come with me!" Zhu Yunxi brought Xu Huaijin to the lake.

The generals have been paying attention to King Wu, hoping that he can solve the immediate crisis.

Seeing that he brought Xu Huaijin to the lake to do experiments, they all followed.

"Xu Huaijin, pull out that hairpin of yours and use it for me." Zhu Yunxi said.

Xu Huaijin didn't seem to know Zhu Yunxie, he was actually interested in women's things!Hairpins, he wants to use hairpins!

"Don't worry, I'll pay you back after using it, it's just an experiment."

Xu Huaijin pulled out the hairpin, and Zhu Yunxi threw it on the lake.

"you?!"

Xu Huaijin was so angry that he used the hairpin, you just use it like this, you threw it away for me, and threw it into the water!

This hairpin was left to me by my mother, it's my own thought!

He threw my thoughts into the water!
Xu Huaijin quickly reached out to grab it, but was grabbed by Zhu Yunxie.

Huh?
Xu Huaijin discovered a strange thing: the hairpin was lying flat on the surface of the water and did not sink into the water!

The others who followed were also stunned.

King Wu, is this juggling?
It was a stone just now, and the stone floats on the water, mainly because there are many pores in the stone, which makes it lighter.

Now it is actually a hairpin. This hairpin looks like pure gold. Could it be that there is a hole in the middle?
No, Xu Huaijin comes from a family of generals, and is the jewel in the palm of Xu's family.

The hairpins she wears must all be pure gold, there can't be holes in them.

But how can the golden hairpin float on the water?

"Everyone is very strange, isn't it?" Zhu Yunxi said, "How about you taste the lake water first?"

Everyone held up the lake water and tasted it.

"This water is bitter, astringent and salty!"

"Yeah, water, why is it salty?"

"Who put salt in it?"

Zhu Yunxi heard it funny, the old uncle is too funny, such a big lake, put salt?How much salt should be put in?

In Daming, salt is hard currency, who is willing to throw salt into the lake?

"The water is salty because there is salt in the water. There are two effects of salt in the water."

Zhu Yunxi explained: "The first effect is that the water is not easy to freeze. This lake is not only a hot spring lake, but also a salt lake, so it is not easy to freeze."

"Second effect, the presence of salt in the water makes it much denser than clear water, and the denser the water, the more buoyant it is."

"Everyone who has lived by the sea will know that swimming in the sea is much easier than swimming in rivers, because sea water contains salt and its density is relatively high."

The family of Liu Haiwang, one hundred households in Huoqiying, is on the coast of eastern Zhejiang, and he immediately proved Zhu Yunxi's point of view.

"This is the famous Dabancheng Salt Lake!"

"It is very difficult to explain buoyancy and density to people of this era!"

"The average salinity of sea water is 30.00%. The average salinity of Dabancheng Salt Lake is [-]%, second only to the Dead Sea."

"Whether an object sinks or floats in water depends on the density ratio of the object to the water. When the density of the object is greater than that of water, the object will sink into the water. When the density of the object is less than that of water, it will float on the surface of the water. Dead Sea The density of the sea water is higher than that of the human body, so a person falling into the four seas will naturally not sink.”

"This is the origin of "the dead sea never dies"."

"Dabancheng Lake is rich in raw salt and Glauber's salt. After the salt from the surrounding mountains and highlands is washed down, it is gradually deposited in the salt lake."

Zhu Yuanzhang couldn't help sighing at this time, maybe the third grandson doesn't have any military strategies, but he knows a lot!

His knowledge and understanding of mountains, rivers, geography, and natural scenery far exceeds that of ordinary people, and it is these that make up for his lack of battlefield experience.

And his knowledge is very practical, and it is cold knowledge that many other generals lack.

Relying on these cold knowledge, the third grandson often makes unexpected moves, and it is precisely these unexpected moves that become the strategy to break the game!

With Liu Haiwang's proof, Xu Huaijin finally breathed a sigh of relief.

I took the hairpin from the water and put it back on again, but it still didn't sink!
Xu Huaijin really admired Zhu Yunxi at this time, how did he know this?
Definitely read the book!

Xu Huaijin thinks that there are not many people who have covered more extensively than her. In addition to reading military affairs, she also reads various miscellaneous books.

Unexpectedly, Wu Wang Zhu Yunxie has such a wide range of knowledge!

In the past, people said that Zhu Yunxi knew nothing, it was really a prejudice!
There is also a possibility that those who study with Zhu Yunxi are all jealous of him!So slander him!
It's just that King Wu has always been aloof from the world, and he doesn't bother to explain to everyone.

At this time, Xu Huaijin's white horse "咴咴" barked, as if he also knew its fate.

Xu Huaijin stood up and saluted Zhu Yunxi, expressing his thanks.

Pingan also said excitedly: "King Wu, shall we cross the water?"

Zhu Yunxi said: "It's not enough to cross the water like this. We are all wearing down jackets, and if they are stained with lake water and salted inside, they will harden!"

"These pumice stones just aren't enough."

Is King Wu's request too high?
It is a great joy to be able to cross the lake before the barbarians, and to be able to transport all the people and livestock to the opposite side!
The king of Wu actually wanted to cross the water without getting wet!
How can this be?
