"Cao Chong calls an elephant?"

"What does Cao Chong call an elephant? It's Cao Cao's son, Cao Chong, right?"

"Aren't you talking nonsense? It must be that Cao Chong!"

Li Chengfeng smiled and said: "That's right, that's Cao Cao's son, Cao Chong is called Cao Chong!"

"Back then, Cao Cao posed a difficult problem to everyone, saying, who can calculate the weight of an elephant? Cao Cao rewarded him with money!"

"At that time, this was a very difficult problem! But Cao Cao had a clever son named Cao Chong! Cao Chong drove the elephant onto a big boat, and then carved a mark on the body of the boat where the water level spread!"

"Then, Cao Chong drove the elephant down again and put a lot of broken stones into it. When the water level reached the mark on the hull, Cao Chong asked people to stop and put the stones. Then, they only needed to weigh the stones. That's enough to figure out the weight of the elephant! Right?"

"Actually where we are, this is just a very simple algorithm, called the law of conservation of matter weight!"

"The law of conservation of matter? This... what is this thing?"

At the beginning, those ministers listened with great interest to Li Chengfeng's story about Cao Chong calling an elephant.

But when they heard about the 'Law of Conservation of Matter' later on, they felt like they were listening to the bible.

Because the eighth prince can always say something that they don't understand at all!

Facing the doubts of many ministers, Li Chengfeng also smiled and said: "The law of conservation of matter weight is different from the law of conservation of matter energy! For example, a catty of cotton and a catty of iron, which one is heavier?"

"Is it iron?" A minister who did not study much said suddenly.

Li Chengfeng immediately patted his forehead heavily, and said: "What ghost book are you reading? A catty of cotton and a catty of iron are both a catty. Who weighs the most? Of course they weigh the same, idiot! Don't be a minister. Now, go back and farm for me!"

"Hahaha…"

When Li Chengfeng said this, the ministers immediately burst into laughter.

Li Shimin also followed, laughing loudly.

Because the moment when Li Chengfeng tells the story is really interesting, and not only is it very interesting, but he can also learn a lot of truth from it.

Yes, a catty of cotton weighs the same as a catty of iron.

But humans often feel that iron is heavy and cotton is light.

But they ignored it, this is under the same weight! So it can only be said that the two substances are modified in the same weight, with less iron and more cotton, rather than heavy iron and light cotton.

Li Shimin stroked his beard with a satisfied smile on his face.

Because he was also confused just now, whether it weighs a catty of cotton or a catty of iron.

When he came back to his senses, he realized that they were the same weight, but the concept was different!

"Haha, it's interesting, Feng'er, go ahead and talk, what method will you use to get that boulder in the river bed up?"

Li Shimin found it very interesting, so he wanted Li Chengfeng to continue talking.

Immediately afterwards, Li Chengfeng said unhurriedly: "The first method is, we dig a super huge pit on the opposite side of the boulder!"

"The pit needs to be at least two meters deep! Then we are making a super large scale, just like weighing things, to weigh out that huge stone? This method is called the law of conservation of matter. I don't know everyone. Did you understand this statement?"

"Ding, surprise from Li Shimin, naughty value +188!"

"Ding, the shock from Wei Zheng, naughty value +176!"

Many ministers were shocked by Li Chengfeng's sudden method.

Even Li Shimin himself was extremely surprised.

That's right, why didn't he think of this method?

As long as you need a large enough scale, you can weigh out this huge rock!

Such a simple method, why can't I think of it?

"Okay, okay, I finally know why the Eighth Prince prepared iron chains, stones, and big tree trunks?"

Li Shimin suddenly said with great ambition: "The purpose of the eighth prince is to use a large scale to weigh out the huge rock under the river bed! So, what we have to do now is to dig a huge hole here, isn't it? Ah Fenger?"

Li Shimin looked at Li Chengfeng with a smile, and also wanted to show off in front of the ministers.

However, Li Chengfeng frowned, shook his head and said, "No, father, this is just the first plan I mentioned, but what I want to use is the second plan!"

"Ah? So, you don't intend to weigh out the boulder?"

Li Shimin immediately felt that he was very ashamed.

Li Chengfeng shook his head and continued: "That's right, because the second plan is simpler than the first one, at least the second plan doesn't need to dig a hole, and doesn't need to prepare a basket that can hold 100,000 catties of stones , come to weigh the stones!"

"Then, Feng'er, what is the second plan you have prepared?"

At this time, Li Shimin and all the ministers looked at Li Chengfeng very curiously.

Transport the 100,000-jin boulder ashore. Hundreds of civil and military ministers in their court spent more than a month, but they couldn't think of a way.

But as soon as Li Chengfeng came, he thought of several ways!

Is this the gap between people? Is this the difference between genius and mediocrity?

Li Shimin used to think that there was no difference between people except their birth status, but after meeting Li Chengfeng, he discovered that there is really a big difference between people.

Some people are born smart and some people are born stupid.

Some people are born with kind hearts, but some people are born untaught, but they are extremely insidious and cunning!

Perhaps this is the gap between people.

"Feng'er, tell me your second thoughts, okay?"

"Okay, you guys will know what my second thought is later!" Li Chengfeng said confidently.

Because the first thought is much more complicated than the second thought.

Another big hole had to be dug, and a big wall that could hold a hundred thousand catties of stones had to be prepared, which would waste a lot of Li Chengfeng's time.

So Li Chengfeng might as well just choose the second method~lightnovelpub.net~ to make a fulcrum, and then hoist a huge stone weighing 100,000 jins up!

…

Soon, Li Chengfeng ordered his servants to pile up a fulcrum more than two meters high with dozens of huge stones at a location he had chosen.

From a distance, it looks like a small hill.

Li Chengfeng also deliberately dug a groove above the fulcrum, so that the fulcrum made in this way is not easy to slip.

Then the next step is to wait for Cheng Yaojin and the others to transport the trunk back!

"Eighth prince, eighth prince, the veteran is back!"

Say Cao Cao, and Cao Cao will arrive.

Just now Li Chengfeng was still chanting, saying why Cheng Yaojin hasn't come back yet?
