Water Margin: The opening scene involves assassinating Emperor Huizong of Song and forcibly taking L

Many things are simply inexplicable.

The only way forward is for each discipline to develop gradually and promote each other.

Xu Guanzhong took the physics book written by Zhao Yuan.

I glanced at it briefly.

It includes a principle explanation.

There are also designed experiments that can verify this.

It seems that this entire field of knowledge can be verified through experiments.

However, those conclusions seem somewhat unreliable.

This experiment was designed to verify that two objects of different weights fall at the same speed.

He subconsciously felt that heavier objects should fall faster.

However, he also felt that since King Liang dared to write down something so easily verifiable as to be right or wrong...

There should be a high degree of certainty.

Chapter 1724 Hot Air Balloon

Xu Guanzhong secretly decided that he would conduct an experiment when he returned.

The next page actually says buoyancy.

Water has buoyancy, and so does air.

The buoyancy chapter has only just begun.

No experiments were designed.

Xu Guanzhong couldn't help but ask curiously,

"Water has buoyancy, so we can swim."

"But if air also has buoyancy,"

Why can't we float?

Zhao Yuan laughed and said, "If the air had no buoyancy..."

How can a Kongming lantern fly?

Upon hearing this, Xu Guanzhong

I couldn't help but be stunned.

Everyone knows that Kongming lanterns can fly.

However, the underlying reasons are not fully understood.

Xu Guanzhong couldn't explain it either.

Hearing Zhao Yuan explain buoyancy using Kongming lanterns,

That makes some sense, though.

But after thinking about it, he added,

"Then why can it only rise after being ignited?"

Zhao Yuan laughed and said, "Even a stone can't float in water."

"But if you put the stone on the boat, it will float,"

"That's because buoyancy is greater than gravity,"

"That's why it can float,"

"If you keep putting stones on the boat, it will sink."

"Before being lit, the weight of the Kongming lantern is greater than its buoyancy,"

"Naturally, it won't float."

"After the fire is lit, the surrounding air will expand due to the heat,"

"The density decreases, and then it rises, squeezing out the cold air from the Kongming lantern."

"When the weight inside the Kongming lantern is less than the buoyancy it experiences from the air,"

"And so the Kongming lanterns were raised."

Although Xu Guanzhong was intelligent,

But I was still confused by terms like thermal expansion and density.

Zhao Yuan saw that Xu Guanzhong looked completely bewildered.

Knowing he hadn't understood, he smiled and said...

"Wait until I compile it into a book,"

"You can take your time reading it,"

"It's actually not hard to understand."

Zhu Wu suddenly said, "The boat can carry people."

Can Kongming lanterns carry people?

Zhao Yuan smiled and said, "Of course."

"We just need to make a larger hot air balloon to carry people."

Upon hearing this, Zhu Wu immediately replied,

"If the hot air balloon flies higher than the car,"

"Then we can use hot air balloons instead of nest vehicles to observe enemy positions."

Zhao Yuan thought for a moment,

"Hot air balloons can fly thousands of feet high,"

"But we might not be able to build a hot air balloon like that,"

"How high exactly can it fly?"

"We'll know once we build the hot air balloon."

Zhu Wu was thinking more about battle.

He said with a wildly imaginative look on his face.

"If we could control the direction and takeoff/landing of the hot air balloon,"

"Load some fire mines on it,"

"Then wouldn't we be able to bomb the enemy from above?"

Lin Chong and Xu Guanzhong listened,

He was momentarily stunned.

The army had just assembled.

Suddenly, a fiery thunderbolt fell from above.

Amidst the enormous explosion,

The people around were torn apart.

Blood and flesh flying everywhere

The flying metal fragments also killed people in the distance.

The newly assembled troops were bombarded by fire and thunder.

It descended into chaos, even collapse.

This is the real divine thunder.

Just thinking about it...

The two felt that this combination was enough to influence the course of the battle.

Zhao Yuan rode in a hot air balloon while traveling in later generations.

Therefore, I know some things about hot air balloons.

The wind direction is different at different altitudes in the air.

Hot air balloons change direction by adjusting their altitude and taking advantage of winds from different directions.

However, knowing something doesn't necessarily mean you can do it.

Everything requires experimentation.

Only then can we know what we can do now.

Zhao Yuan laughed and said, "Theoretically, it's all possible."

"But all of this requires a lot of experimentation."

"However, it is easy to get a hot air balloon carrying people into the air."

Xu Guanzhong said, "If it were possible to carry people and fly,"

"It would be much easier for the King of Liang to destroy the religion."

"As long as King Liang delays announcing the principles of hot air balloons for a while longer,"

"The people saw people flying into the air,"

"They will definitely think this is the divine power of the King of Liang."

"No religion can make people fly,"

"Only the King of Liang can make people fly."

"King Liang said they were all fake,"

"The common people will naturally think they are fake."

"Wait until all religions are destroyed,"

"King Liang will explain this principle again,"

"By then, apart from a few people, no one will remember those religions."

Zhu Wu laughed and said, "King Liang doesn't need to say anything."

"They then pretended it was an experiment by the Ministry of War using hot air balloons,"

"I accidentally ran out of the camp,"

"Just let the people see it."

"As long as the King of Liang doesn't explain,"

"They will naturally regard it as a miracle."

Zhao Yuan has decided to popularize science.

Naturally, he no longer wanted to impersonate a god.

Hearing that Zhu Wu could free him...

He nodded silently.

Chapter 1725 The Imperial Academy Begins Lectures

Xu Guanzhong added, "We can use a two-pronged approach."

"On the one hand, they created a deity, making the image of King Liang as a god descended to earth deeply ingrained in people's minds,"

"On the one hand, it exposes some common religious deceptions,"

"To make the people doubt religion."
