Three Kingdoms: The Crown Prince of Wei, betrothed to Sun Shangxiang at the beginning

"Awen, why does the third brother hate me so much?" Cao Chong looked depressed and pretended to be a good baby in front of Cao Cao.

Why Cao Chang hated himself, Cao Chong knew everything in his heart, but he just wanted to pretend not to know and pretend to be innocent in front of Cao Cao.

After all, he is still a child, and his natural advantages must be brought into play.

"Alas~" Cao Cao rubbed his beloved son's head, and for a while he didn't know how to explain, he could only say: "Your third brother has a bad temper, so don't take it to heart." "

"Hmm." Cao Chong nodded obediently.

On the side, several advisers gathered together to speak.

When Guo Jia saw this scene, he couldn't help but sigh with emotion: "Although Chong Gongzi is smart, he is still simple in heart, and I don't know that he has become a thorn in the eyes of the princes. "

"Smart and simple, I don't know if it's good or bad?" Xun Yu followed closely and spoke.

"You'll understand when you grow up." Cheng Yu didn't say much.

"It's not a good thing to show it blindly and don't know how to hide it." Jia Xu commented.

Full of losses, humble benefits.

Cao Chong did not know such a truth, but Cao Chong could not do the golden mean.

The reason is simple, Cao Chong is not the eldest son.

If you want Cao Cao to give birth to the idea of "abolishing the long and standing young", then Cao Chong must show his crushing excellence in order to make Cao Cao make up his mind.

If Cao Chong played moderation and Cao Pi also played moderation, then in the end Cao Cao would definitely choose Cao Pi.

Anyway, it's the same, why would Cao Cao risk the world's great disapproval to abolish the elder and young?

Cao Chong must show his own excellence and give Cao Cao a reason to abolish his long life.

"Chong'er, what the hell is going on with you?" Cao Cao suddenly asked, "Why can you make seawater drinkable with such a touch?" "

Cao Cao was really curious about the principle and wanted to get the answer from Aiko.

When the surrounding Wen Wu Qunchen heard this, they couldn't help but all come together, all wanting to hear Cao Chong explain the principle.

"As we all know, sea water is salty and people will die if you drink too much, but few people know why they die, only that the more they drink, the thirsty they get."

Cao Chong explains: "For example, if a person drinks a bowl of seawater, then in order to expel the salt in the seawater, the body needs to consume one and a half bowls or even two bowls of water to expel all the salt. "

"Can't make ends meet?" Cao Cao listened half-understood.

"It can be understood that way." Cao Chong nodded immediately, "Drink a bowl of seawater, in order to drain the salt, you need two bowls of water, so the more you drink, the more you lose, and finally the person will die of dehydration." "

"So, as long as we remove the salt from the seawater, or remove most of it, then it is completely drinkable."

"Everyone understands the truth of boiling salt, boiling seawater leaves salt, then what escapes is fresh water that can be drunk." Cao Chong pointed to the water vapor, "As long as you find a way to leave them behind, you can get fresh water." "

First cover the pot with a layer of clothing, then cover the pot, water vapor will naturally wet the clothes, retain some moisture, and then wring out the clothes to get fresh water, or not so salty seawater.

This soil method cannot remove 100% of the salt, which is why Cao Chong has a small amount of salt on his clothes.

But this method can remove most of the salt, drink a bowl of water, the human body may only need to consume a small half bowl of water, can discharge excess salt, so that you can surplus a part of the water, to achieve the effect of quenching thirst.

"It's a fantastic idea."

The principle is not too complicated, Cao Chong can speak as plainly as possible, most people can understand it, and they are full of praise for Cao Chong's method.

"How did Chong Er learn about this law?" Cao Cao couldn't help but ask.

"Read it in the book." Cao Chong prevaricated casually.

"Which book?"

"Uh..." Cao Chong said helplessly, "The child thinks it himself." "

"You boy." Cao Cao said angrily: "What a modestness." "

"Hey, hey." Cao Chong could only laugh dryly.

"The drinking water problem is solved, let's discuss the marching strategy." Cao Cao's tone was decisive.

Anyone can see that Cao Cao is unwilling to withdraw from the army three times and twice, as if he is determined to fight.

"Master." Guo Jia hugged his fist and said, "Since Chong Gongzi's method can make the sea water drinkable, it is better for us to march along the sea to Liaodong, and then we don't have to worry about drinking water." "

"Can I go?" Cao Cao looked at Tian Zhuo.

"Yes!" Tian Zhuo said without thinking: "The coast can directly enter Liaodong, although there is no road, but the terrain is relatively flat. "

"The reason why no one walked before was because there was no water on this road." Tian Zhuo said and looked at Cao Chong, "But now it's not a problem at all. "

The road Tian Zhuo said is the Liaoxi Corridor, and the starting point of this road in history is the famous Shanhaiguan.

Of course, there is no Shanhaiguan yet, but this road has long existed.

To the north is a continuous mountain range, to the south is an endless sea, and there is such a corridor between the mountains and the sea, which is also the origin of the name of Shanhaiguan.

"Master." Xun Yu said excitedly: "We retreated again this time to find water, presumably Wuhuan must think that we withdraw, maybe we can take it by surprise." "

Cao Cao sent troops to Wuhuan, and for the first time had to retreat due to road rain, pretending to withdraw his troops.

The second time he attacked again, he retreated to the sea because of the lack of drinking water.

Now to march again, that is the third sortie.

Three sorties, three different routes, Wu Huan should have deceived even if he was vigilant.

"Good! Then follow this path! "

Cao Cao was full of pride, and with a wave of his hand, he ordered to leave.
