Archimedes' law is a fundamental principle of mechanics in physics. An object immersed in a liquid (or gas) is subjected to a vertical upward buoyant force, which is also the force of water on the object, and the magnitude of the buoyancy is equal to the gravitational force of the liquid or gas dislodged by the object.

This law will not be transmitted to China until more than a thousand years later, so the people of the Eastern Han Dynasty do not know it.

Therefore, Qin Feng would not explain this law to these people in the Eastern Han Dynasty, he simply said: "This method is divided into three steps, the first step is to put the elephant on the boat first." In the second step, the hull of the ship sinks heavily and the imprint is carved as a mark, and the third step is to drive the elephant out and put the stone in it to reach the imprint. ”

"The weight of this stone is the weight of an elephant!" Qin Feng finally smiled.

At the venue, everyone was stunned for a while, and then the pot exploded.

Liu Bei hurriedly asked, "Strategist, how about Mr. Heshan's method?" ”

Zhuge Liang's swollen bell-like eyes blinked, and he couldn't help but praise: "Good way!" ”

Liu Bei was overjoyed when he heard this, and said in his heart that my subordinates had come up with this method, and his reputation came. also praised: "Mr. Heshan is really wise, and being able to get Mr. Heshan's help is really a blessing from his previous life." ”

Qin Feng rolled his eyes when he heard this, and said reluctantly: "Pass the prize!" ”

And Cao Cao on the side muttered to himself, "Idiot Liu Xuande, you said that you didn't hurry up to marry a beautiful daughter-in-law, and in the end, you idiot threw away the perfect beauty." The beauty followed Qin Feng, and if she wanted to come to Qin Zijin, she would have done it a long time ago. You stupidly asked Qin Feng to help, but fortunately, Qin Zijin left quickly, if you stay for a few more days. It's no wonder if you don't play to death! ”

Liu Bei naturally didn't know this, otherwise he would have to fight hard with Qin Feng.

Now. Liu Biao and the others also figured it out and couldn't help but agree.

"Mr. Heshan is really a good way!" Yi Zhi praised from the bottom of his heart.

Qin Feng's method. will save the face of Shangbang, but Cai Mao, Zhang Yun and others are unwilling, and they say that the limelight has been robbed of Heshan, which suddenly appeared.

The chief representative of the state here is Liu Biao, so Liu Biao smiled happily and said: "Mr. Heshan, good way, everyone, come with me, go to the river to watch!" ”

Everyone followed Liu Biao to the river outside Xiangyang City. At this moment, a large boat was already parked on the river.

Qin Feng ordered Wu Lijin to lead the elephant to the boat, the elephant was docile and immovable, and after the boat was stable, Qin Feng took out his sword and carved a deep imprint on the side of the boat at the level of the water.

Subsequently, Qin Feng ordered Wu Lijin to bring the elephant back to the shore and ordered the soldiers to load large and small stones onto the boat. The hull sinks a little heavier, when the draft comes to the imprint. Qin Feng hurriedly stopped.

Nowadays, everyone understands that the weight of an elephant can be known by simply weighing the stones and adding up the weights.

The eyes of the crowd widened. They were a little confused at first, but now that they have figured out the way, they can't help but praise twice. "Good way, good way!"

The barbarians were the most excited. Wu Lijin said excitedly: "Sir is really a great wisdom, solve the doubts of our people." Please be worshiped by the villain! ”

Busy and Abbassy also saluted.

"Strategist, what a good way!" Liu Bei was dancing, he wanted everyone to know that the person who came up with this good solution was his Liu Bei's military advisor.

Zhuge Liang, whose pig's head was not swollen, shook the feather fan very quickly. Because now Qin Feng has shown enough intelligence to make Zhuge Liang feel that his status has been threatened, especially after Liu Bei is honored as a military advisor. His eyes couldn't help but look at Cao Cao, who was excited, and said secretly: "You must find out the handle of this Heshan, his only subordinate is the breakthrough!" ”

Cai Mao, Zhang Yun and others felt particularly faceless.

After a while, a small colonel ran over excitedly and said, "Lord, 11,350 pounds, so heavy, what a behemoth in the world!" ”

More than 10,000 catties, which made people who guessed thousands of catties exclaim. They couldn't believe that there was such a weight of beast in the world.

"It's really a divine beast!" People can't help but praise.

Wu Lijin and the others have a lot of face, and now they finally know how heavy an elephant is, and then they bowed and said: "Thank you, Lord Heshan, for solving the confusion of the villain!" ”

Qin Feng smiled kindly, and when he saw Liu Biao and the others looking shocked, he sneered and said with a smile: "This is a divine beast?" If you throw a 100,000-pound whale in this sea, you must not bow down and worship God! ”

"Whales! 100,000 catties! Everyone was stunned for a while.

"Heshan, don't be alarmist here, there may be 100,000 catties of beasts there! What is it called a whale, the largest fish is a tall person, how can it be 100,000 catties! Cai Mao said dissatisfiedly.

Qin Feng waved his hand disdainfully and said, "The whale is a sea beast, in the deep sea, it's a pity that General Cai is on this river, I'm afraid I won't see it in this life!" ”

Cai Mao managed the water army in a good way, and asked a series of questions when he heard the ridicule: "It's really a big joke in the world, have you seen Heshan?" What boat did you go to sea? Where can a great ship sail on the sea? ”

In the Eastern Han Dynasty, people couldn't hike at the same time, and they couldn't go to the ocean, so even if they were a great talent like Zhuge Liang, they didn't know about elephants, and they didn't know about whales. Qin Feng was very sad about the ignorance of the ancients, so he disdained to argue about it.

And Cao Cao couldn't see Cai Mao's arrogant appearance, and said in his heart that your Jingzhou Navy must be very powerful? He immediately retorted, "There are giant ships in the Northland, and the Chaos class ....... ”

"Shut up, you!" Qin Feng said.

Cao Cao suddenly realized, and said in his heart that he almost showed clues.

"Chaos level, Yedu!" Cai Mao's face changed greatly when she heard this.

The faces of the people in Jingzhou all changed greatly, and they suddenly lost their mood.

Cai Mao held on and said disdainfully: "Hmph, I have tens of thousands of fireships, and no matter how big the battleship is, it can burn him without leaving a single piece of armor." ”

Cao Cao secretly scolded the idiot, and said that Qin Zijin would be stupid enough to only send a boat to beat you? You have a small ship, does Qin Zijin have it?

The faces of everyone in Jingzhou changed greatly, but Cao Cao breathed a sigh of relief for no reason, and said in his heart How did Qin Zijin's head grow, and he was able to build such a huge ship, but fortunately, the main force of General Ben was the army. When Qin Feng is defeated and his battleship is obtained, Jiangnan is at your fingertips!

Barbarian Wu Lijin and others. I didn't know the details until I asked. The heart said that the north was prosperous, and he would send an elephant to Prime Minister Qin another day. It must be better than giving it to this Liu Jingzhou!

At the end of the Eastern Han Dynasty, the world was in turmoil. Princes compete for hegemony.

The sheer size of the Chaos-level Yedu aroused endless worries among the people of Jingzhou, the water town. At this point, Liu Biao and others were interested, and the banquet was over.

Qin Feng called the elephant, this method of weighing in water, which was widely spread and was called Heshan's law. It was not until the 17th century that Archimedes' law was transmitted to the Han land, and the Han people scoffed at it.

18th century AD. Historians found classics in ancient tombs, and only then did they know that Heshan was Qinfeng. Since then, Heshan's law has been known as Qinfeng's law, which has replaced Archimedes' law under the strong promotion of China and has been circulated in the world. Since then, Qin Feng has added the title of a great scientist to the evaluation of later generations.

If Qin Feng knew, he would definitely be very embarrassed, and he would definitely say, "Dear Uncle Archimedes. This is all made up by later generations, and the prime minister himself really doesn't mean to rob you of your law! ”

……

Qin Feng returned to the post house, the post house had a separate courtyard and a single room, and Qin Feng, as Liu Bei's honored guest, had a separate courtyard to live in.

"Zijin. Zijin, 10 million runs, buy the manufacturing blueprints of your Chaos-level Yedu for my brother! Cao Cao chased all the way back to the courtyard. said with a flattering face. He had sent people to steal the technology of the Northern Earth Academy many times, but many people had died, and he never succeeded.

Qin Fengxin said don't talk nonsense. The south relies on the water army, and the technology gives you. You beat down Jingzhou and Jiangdong, and you are still a fart.

"Fifteen million guan!" Cao Cao screamed. Naturally, he also knew the importance of the ship for the south. Just defeat the navy, and the army of Sun Ce and others will win a piece of cake.

Peng, Qin Feng closed the door.

Cao Cao, who caught up, bumped into his nose, "Oops, damn Qin Zijin!" He rubbed his nose and looked at his room painfully, "Isn't it a battleship, this general can also build it, but unfortunately, it always capsizes!" Cao Cao finally sighed, he had indeed built a giant ship, but he did not have keel technology, and it would turn over if he drove a little faster or a big wave.

"Bloodshed! Damn it! Cao Cao found that his nose was bleeding, and while scolding Qin Feng, he hurriedly turned around and went outside to fetch water to wash.

Wow, wow, Cao Cao carried the well water, he suffered a hardship that he had never experienced in his life in Jingzhou for more than a month, "I must return to the Central Plains as much as possible...... and find ten or eight little girls to serve General Ben, hehe!" ”

Just as Cao Cao was about to bring out the bucket, a fragrant wind came. Cao Cao's nose sniffed suddenly, and he hurriedly looked up to find it, and he was stunned for a moment.

I saw a young woman passing by in the distance, beautiful as a flower, with a slender body, and a water snake waist writhing while walking, which can make all men crazy. Suddenly, this beauty turned her head, and when she saw Cao Cao, she raised her silk scarf to cover her mouth and smiled, her smiling big eyes were amazingly seductive, and the charm of her delicate body had reached her bones.

With a bang, Cao Cao's hand loosened, and the bucket fell straight to the bottom of the well. At the same time, nosebleeds flowed wildly.

Seeing this, Mei Ji trembled with laughter, let go of her hand, and the silk scarf she was holding flew out with the wind.

Coincidentally, it fell on Cao Cao's face.

Cao Cao hurriedly took it down, and when he looked over, he saw Mei Ji's shyness and hurriedly left.

"Holy!" At this moment, Cao Cao, who had been holding back for a few months, had countless insects crawling in his head. "Jinpa is merciful, and Yanfu is not shallow!" He immediately subjectively judged that this was a rare encounter, and he hurriedly wiped the nosebleed with a silk scarf, took three steps and two steps, and chased after him.

There was a beautiful girl in the post house, and I didn't know it was from that big family, and the news quickly spread among the men in the post house.

Cao Cao thus learned where the courtyard where the beauty lived, and due to the attention of many people, Cao Cao could not find the opportunity to get acquainted.

Soon it was night, in the dead of night, when there was a movement in Qin Feng's room. Cao Cao, who was rolling around on the bed in his room, could no longer resist the urging of the insects in his brain, turned over and got up, carefully walked out of the courtyard, and looked at the courtyard of the beauties.

No one went in and out at night, and when Cao Cao avoided two groups of night patrols, he came to the gate of the courtyard, and subconsciously put his hands on the door, who knew that the courtyard door was opened. "Sure enough, it's an affair, and this is still for me to keep the door!" He was stunned for a moment, then walked in, and suddenly found that several subordinates had fainted in the courtyard.

In the master bedroom, there was a coquettish cry, and there was no movement.

"There are thieves!" Cao Cao was taken aback, but he immediately thought that this was an opportunity for a hero to save the beauty, "Save your life, repay you with your body, hehe!" ”

He immediately gathered his wide sleeves, pulled out the sword at his waist, and sneaked in. (To be continued......)
