Da Qin: I exposed myself as a time traveler, why are you Zhao Gao panicking?

Chapter 175 Immortal magic? ! Saltpeter melts ice!

When the craftsmen heard this, although they still had doubts in their hearts, seeing Qin Chi being so confident, they couldn't help but feel a little curious and expectant.

They knew that this young man never played according to common sense, but he always brought surprises and breakthroughs.

Maybe this time, he can really create an unprecedented miracle.

Upon seeing this, Qin Chi raised the corner of his mouth slightly, revealing a meaningful smile, but he did not immediately clear up everyone's doubts.

He calmly took out a piece of iron as thin as a cicada's wings from his sleeve, and everyone stared at it, puzzled by its meaning.

Qin Chi gently held the piece of iron and slowly placed it on the water.

When all the craftsmen saw this, they were all dumbfounded, and their surprise was beyond words!

Under their astonished gaze, the thin piece of iron floated on the water as lightly as a fallen leaf, rippling slightly with the waves!

But it didn’t sink into the water as they expected! !

For a moment, everyone looked at each other with doubts in their hearts.

They all knew that metal was heavy and would sink when it entered water, but what they saw in front of them completely overturned their understanding!

The iron piece floating in the water seemed to them to be a strange and unbelievable thing.

Qin Chi saw the surprised expressions on everyone's faces, but he had already expected it!

He knows very well that if he wants to break the rules and bring out the new, he must first subvert the old concepts and lead everyone out of misunderstandings!

The scene before him was an excellent opportunity for him to demonstrate scientific principles to everyone and enlighten their thinking.

"This...why is this?" A master craftsman couldn't help but ask.

Qin Chi smiled and explained: "This is because the buoyancy of water is greater than the gravity of the iron piece."

"As you all know, the sinking and floating of an object depends on its gravity and the buoyancy force it experiences."

“If the gravity is greater than the buoyancy, the object will sink, and vice versa, the object will float. The buoyancy of water is equal to the weight of the water displaced by the object. Therefore, as long as the hull is made large enough and enough water is displaced, it can Make the boat float on the water!"

Qin Chi looked around with a smile and saw the shocked expressions on the faces of the craftsmen. Knowing that they had understood something, he slowly said: "Do you know that the principle of things has a degree of ups and downs? It's not that things can't float, it's that we don't know. It makes sense."

A master craftsman raised his hand and asked: "What the adults said makes the villain suddenly enlightened! But how can the iron ship maintain buoyancy and not sink to the bottom?"

Qin Chi replied: "That's a good question! The key lies in the design of the hull."

"The hull must be hollow and the bottom slightly curved to displace more water!"

"At the same time, the upper part of the hull must be made wider to increase buoyancy!"

"In this way, the iron ship can float lightly on the water."

Another craftsman sighed: "Master Qin is really a god! We are stupid, but now we know how big the world is, and there are all kinds of wonders! With this principle, why worry about building an armored warship?"

Qin Chi shook his head and smiled: "It's not me who is a god, but the power of science."

"As long as you master scientific principles, you can turn decay into magic!"

"You are all highly skilled craftsmen, and you only need to change your mindset a little to join in the great work."

After hearing this, all the craftsmen expressed their agreement.

Their admiration for Qin Chi increased even more!

Although what Qin Chi said is only a few words, it shakes the soul of every craftsman like bells in the morning and drums in the evening.

Their originally confused expressions gradually became clearer under Qin Chi's explanation.

As if awakening from a dream, as if receiving enlightenment, all the craftsmen nodded in agreement, with sincere admiration and shock in their eyes.

It turns out that the armored warship is not as unbuildable as previously thought.

As long as you master the scientific principles and skillfully use the balance of buoyancy and gravity, you can make heavy metal sail freely on the water. Such an idea was simply a fantasy before, but now, with Qin Chi's inspiration, it has become within reach.

The hearts of the craftsmen were full of excitement and anticipation. They seemed to have seen the magnificent sight of armored warships cutting through the waves in the river in the future!

The admiration for Qin Chi is like an endless river!

They knew that this young man not only had extraordinary wisdom, but also had the courage and determination to challenge conventions.

At this moment, Qin Chi is like a god in the eyes of the craftsmen, and every word he speaks seems to contain endless wisdom and power!

……

In the land of old Chu, wars were blazing and war drums were ringing!

Xiang Yu led his troops to fight against Meng Tian's army in the vast wilderness. The two sides were at war with each other, and their momentum was like a rainbow!

However, the war was not going well. Although Xiang Yu's soldiers were brave and good at fighting, they could not withstand the fierce offensive of Meng Tian's cavalry!

For a moment, the battlefield was filled with flashes of swords and shadows, and flesh and blood flying everywhere!

The Chu army retreated steadily and suffered heavy losses.

Meng Tian is a famous general of the Qin State. He is both wise and brave. At this time, he is pursuing the victory without giving Xiang Yu any chance to breathe!

Seeing that the situation was over, Xiang Yu felt filled with grief and anger!

He also knows that while the green hills are still there, he is not afraid of running out of firewood.

So, he made a prompt decision and led more than a thousand of his remaining troops to flee in confusion, hoping to find a hiding place in order to make a comeback!

Everyone fled deep into the mountains and dense forests. The mountain roads were rugged and steep, and the trees were dense and blocked the sky and the sun.

Xiang Yu and others overcame thorns and thorns and moved forward with difficulty.

Fortunately, there are few people in the deep mountains, so it is easy to hide your traces.

After everyone worked hard all the way, they finally found a hidden cave and settled down for the time being.

In the deep mountains, towering ancient trees block out the sky and the sun, and the cliffs are extremely dangerous. This environment is already a desperate situation for ordinary people.

However, for a brave man like Xiang Yu, it failed to destroy his fighting spirit.

Although he is in adversity, he is like a tiger in the abyss, always ready to attack.

At this moment, the cave was dim and the firelight was flickering. Xiang Yu's face was ashen and he was sitting in deep thought.

All the generals were sitting or standing, with expressions of sadness and anger on their faces.

The reason for this defeat was that a man named "Qin Chi" informed the First Emperor of Xiang Yu's identity, calling him a remnant of the Chu Kingdom and intending to overthrow the Qin Dynasty.

This led to Meng Tian killing each other!

What led to Xiang Yu's defeat!

When Xiang Yu thought of this, he suddenly became furious and said sternly: "I swear to kill this thief in Qin Chi!"

"If I capture this thief one day, I will cut his body into thousands of pieces to vent my hatred!"

The generals also shouted angrily and vowed to kill Qin Chi together!

When Fan Zeng saw this, he knew that Xiang Yu was furious, but he also knew that this was not the time to be impulsive.

He took a step forward, cupped his hands and persuaded: "Your Majesty, please calm down!"

"Although Qin Chi is cunning, we must take a long-term approach. The most urgent task is to consolidate the foundation and regain our strength. When the time is right, it will not be too late to seek revenge."

Xiang Yu took a deep breath, suppressed the anger in his heart, and said in a deep voice: "What you said is true. I must endure the humiliation and bear the burden, and Xu Tu plans the future."

"But this thief in Qinchi, I must get rid of him quickly!" He glanced around the generals with eyes like a torch, and continued: "Pass my order to contact your old troops immediately, gather troops, and when the time comes, sneak into Xianyang and capture Qin Chi’s head!”

All the generals agreed in unison, and the sound shook the cave!

A flash of murderous intent flashed in Xiang Yu's eyes, and he had made up his mind!

If Qin Chi is not destroyed, I swear not to be a human being!
