The bright sunshine rose again, and the land of early summer was already full of lush crops. After a severe cold winter, people's mood became lively.

In a field of wilderness, hundreds of people were gathering around.

In the crowd, Zhao Yan was standing there, holding a ball in his hand, and there were more than 20 horses next to him. Among the crowd watching, some people asked in confusion: "Do you want to perform a circus?"

"have no idea."

"What do you know? The General is doing an experiment on atmospheric pressure." Suddenly, a young man holding a pencil and paper in his hand said.

"Atmospheric pressure? What is it?" someone asked in confusion.

"This is something our Academy of Sciences is studying, and I will not be able to explain it to you for a while." Another middle-aged man who was focused on watching the situation in the field said.

These people are all literati and have studied Western learning. There are thirty-two people, all of which are talents dug up by merchants from other places.

Among them, there were even five Western missionaries, Zhao Yan organized these people and established a science and technology academy. The people from the science and technology academy were his students.

One of the missionaries said in fluent Chinese: "Atmospheric pressure? I think there should be no such thing! If there is really pressure, then aren't we crushed to death?"

"Yes! He is just a general, not a scholar. He should lead the soldiers instead of us." said another Westerner.

These missionaries who were proficient in Western learning scoffed at Zhao Yan's desire to teach them. They have been in the Ming Dynasty for quite some time. In general, Oriental people pay more attention to the application of individual objects, but they ignore the knowledge of those systems.

It should be them who teaches them. Instead, this general wants to teach them knowledge. In the words of the Chinese, wouldn’t he overestimate himself?

But to be honest, the general gave a very generous salary, and although he made such unreasonable demands, these missionaries did not stop him.

Instead, they looked at Zhao Yan who was preparing the experiment in the field with great anticipation. This Oriental General would definitely be ruined!

Soon Zhao Yan finished laying out everything in the field, and saw a huge rope tied to each side of the ball, and four tall horses that were already in place on both sides of the rope.

There are eight horses on both sides, and each horse has a groom on standby.

What Zhao Yan wants to do today is to conduct an experiment on atmospheric pressure to prove the existence of atmospheric pressure. He proposed the concept of atmospheric pressure, which was first rejected by Western missionaries.

Westerners in this era did not believe in the existence of atmospheric pressure, so Zhao Yansuo decided to do a hemisphere experiment. In the future, the "Madberg hemisphere experiment" will be changed to the "Zhaojiabao hemisphere experiment".

The ‘Madberg Hemisphere Experiment’ happened in 1654, and now it is 1635, 19 years earlier!

"Did you see this ball?" Zhao Yanshou touched the big ball and said to the onlookers, "This ball is actually separate. It has already pulled out the air inside just now. Let's take a look at the amount of atmospheric pressure now!"

Those who do not understand Western learning are unaware of the word air when they hear it. However, members of the Academy of Sciences know it, and they watch Zhao Yan pull out the air in the two hemispheres with their own eyes.

This hemisphere is very expensive, it took half a month to mobilize the most exquisite blacksmith to create it. The air-secret surname is already very good.

"Prepare, start!" As soon as Zhao Yan finished speaking, the eight grooms urged the horse hard, and the thick rope suddenly tensed up.

The eight war horses were constantly pulling in different directions, and it turned out to be a tug of war.

"Oh! Oh my God, why haven't you opened it?" a missionary exclaimed in the out-of-tune Chinese.

"Stop, add two more horses." Zhao Yan ordered. The tug-of-war stopped. The two grooms on standby quickly led the horse forward and tied the rope to the horse.

"Prepare, start..."

The groom urged the horse again, and the ten horses tried hard to move forward. The horse's hooves made deep marks on the ground, but the balls were still together.

The members of the Science and Technology Academy immediately exclaimed again, and even ten horses could not pull them!

I soon stopped again and took two more heads and went right away.

Twelve horses!

But the ball still did not pull away.

Fourteen horses!

"It should be able to be opened this time!" Everyone thought in their hearts.

But the result was unexpected again, and the strength of the fourteen horses still did not pull the ball away.

It soon increased to sixteen, but the sixteen horses were pulling desperately, and the hemisphere remained motionless.

"Eighteen!" Zhao Yan shouted.

After tying eighteen horses to a rope, the groom urged the horses again!

Soon the two sides entered a stalemate, and the ropes were squeaking.

Suddenly, there was only a loud "pop..." sound, and the horses on both sides suddenly ran forward. The ball was finally pulled apart and turned into two hemispheres. The horses were dragging on the ground while running.

"It's pulled apart, it's pulled apart, eighteen horses!" a member of the Academy of Sciences exclaimed, and everyone cheered for a moment.

"Richardson, do you still think that atmospheric pressure does not exist?" Zhao Yan asked at one of the missionaries with a smile surrounded by everyone.

"General, you are so great. You have helped me get out of my ignorant misunderstanding." The missionary named Richardson shrugged his shoulders, blushed his face and his heart was not beating, as if he had forgotten the theory of "atmospheric pressure" that had strongly rejected Zhao Yan before.

"Yes, General, your greatness is enough to illuminate the entire sky. It is so pleasant to study science under your teachings." An English missionary named Putragues next to him praised.

"Study hard! As long as you can contribute to the scientific research of my Ming Dynasty, your benefits will definitely be indispensable." Zhao Yan patted Richardson on the shoulder.

"General, can we spread the Lord's gospel to every Ming person by contributing to the scientific and technological research of the Ming Dynasty?" Richardson asked Zhao Yan with a solemn expression with a desire.

"We do not allow missionary preaching in the territory of the Ming Dynasty. This is a rule set by our Lord. Even I cannot change it. I also don't want to change this policy. We Ming people do not need the gospel of the Lord." Zhao Yan rejected Richardson's missionary request without any room for maneuver.

"Oh! It's so regretful." Richardson shook his head, but he didn't look too regretful. The four missionaries next to him were the same.

Strictly speaking, they are all pseudo-missionaries, and the primary purpose of coming to the East is not to preach, but to make a fortune. Whether they can preach is not a big problem.

There were also those missionaries with firm beliefs. After all, there were so many missionaries in the Ming Dynasty. Those merchants did not only dig up these five, but those missionaries with firm beliefs all rejected Zhao Yan's temptation to serve him without staying in Zhaojiabao.

"There is nothing to regret, think about it! As long as you can make contributions, you can buy a large estate in Europe, marry a beautiful noble lady, and bring your gospel to those nuns, and live a happier life than the nobles." Zhao Yan said with a smile.

When it comes to nuns, the expressions of these missionaries become very despicable.

This hemisphere experiment ended with a perfect ending.

Atmospheric pressure was confirmed to exist and it was very strong. At the same time, Zhao Yan also impressed the members of the Institute of Science and Technology.

In the words of later people: In the eighth year of Chongzhen, Zhaojiabao hemisphere experiment successfully confirmed the existence of atmospheric pressure, which became a milestone for modern science...
