It didn't take five days, or even three days, for Bao Erhei to make what Su Baiyi wanted.

When Su Baiyi got the things, he couldn't help laughing.

Slightly ugly, to be honest!

Originally, it was made into a round spherical shape, but your sister made it an ellipsoidal shape, not to mention, the surface is not smooth enough, the marks of hammering are obvious, and the two hemispheres are asymmetrical, like a long crooked watermelon.

"Mr. Su, look, this, this ......"

seems to realize that what he has made is indeed a little ugly, and Bao Erhei is not confident when he speaks.

Su Baiyi did not deny this work for the first time, no matter what, it was something that was made by people for two days and three nights.

"It's okay, I'll take a look first!"

Su Baiyi looked at the two things together, and although the gap was not tightly closed, it could be regarded as meeting the requirements. The vent on one side is ugly like an indescribable thing, but it is indeed hollow, and can be combined with the entire inner space of the iron ball.

There are also two hemisphere tethered handles, which are quite plain, but fortunately, they are sturdy.

"Very good, that's it!"

After checking it, Su Baiyi smiled and put the things in his hand on the table.

It's heavy!

"Really?" Bao Er's eyes lit up.

"Of course it's true!"

"Then, Mr. Su, can you ......" Bao Erhei laughed, his black face was shiny and shiny, revealing two rows of teeth that looked unusually white and healthy.

"Okay, I'll teach you how to strike iron in a while!" Su Baiyi was in a good mood.

The test equipment is almost ready, and two more things are needed.

One is a rubber pad to prevent air leakage when the two hemispheres are closed, and the other is a manual air hose for the evacuator.

These two things are naturally difficult for him, so he can buy a natural rubber sheet directly in the system, and then make one on the spot according to the size of the ellipsoid.

Anyway, the rubber tree has now been introduced to China, and I believe many people know it.

As for the pipe for pumping, it is made of iron on the outside, so who cares how it works?

"I don't know, master, why do you use this thing to build?" Bao Erhei's mouth is very sweet, and his heart is also very curious.

After all, if you have worked hard for a few days, you don't know what you're doing, and anyone will panic.

"Have you heard about the atmosphere of Wenzheng Academy?"

"I heard about it, this matter has been spread all over the streets and alleys of Defu, sir, you are really powerful, and I just know that there is really gas in this world, powerful, powerful."

"Don't just slap the sycophants!" Su Baiyi waved his hand: "Since you know about the atmosphere, you should also know that I made a bet with Lord Qin." ”

"Yes!" This kind of interesting story that can extremely arouse people's after-dinner conversation will naturally spread very quickly.

"The power of the atmosphere, just use this thing to prove it to Lord Qin!" Su Baiyi pointed to the iron ball on the table that was divided into two halves, and said to Bao Er.

"What?"

Bao Erhei's eyes sparkled with happiness.

Oh my God, Mr. Su verified the power of the atmosphere, and it turned out to be a weapon I built, I really, I really, really, amazingly.

"Good, good, good!" Bao Erhei was so excited that he didn't know what to say, so he reached out and carefully touched the things he had worked so hard to build again.

The iron ball, which was originally extremely ugly in his eyes, was now made of gold, which made him fall in love.

"First, sir!" Bao Erhei couldn't calm his mood: "When the time comes, can you let me take a look from afar?" ”

"Absolutely!"

This sensational, historically commemorative, and scientific milestone experiment is naturally the more people who watch it, and the more people witness it, the better.

"At noon on the Mid-Autumn Festival, it was at the gate of Wenzheng Academy, no, no, no, the land of Wenzheng Academy was too small." Su Baiyi pondered for a long time, and his eyes looked in the direction of the southwest of Guide Mansion: "Just in the Vulcan Terrace, in the Fire God Terrace, I, Su Baiyi, and Qin Youde have a gamble, and at the same time, let all the people in the Guide Mansion see the power of the atmosphere." ”

"Okay, then I'll wait for you, master, to exert your might and defeat Qin ...... Qin ...... Qin Youde! ”

"Okay, after you go back, help me publicize it, the more people in Guide Mansion know, the better, at noon on the Mid-Autumn Festival, I want to let you see the huge power of the atmosphere at the Huoshentai."

Necessary publicity, still wanted.

……

Bao Erhei was extremely happy, and after returning home, he still couldn't suppress the excitement brought to him by the fact that he had become Su Baiyi's apprentice.

Who is Su Baiyi?

That's the little Zhuge of Guide Mansion, a god-like existence.

What an honor it is to be a disciple of Mr. Zhuge .

Bao Erhei felt that the significance of this was even more significant than finding out that his ancestor was Bao Qingtian.

"Daddy...... I made it, and Mr. Su said that I did a good job and accepted me as a disciple. ”

couldn't suppress the excitement in his heart, and as soon as he got home, he ran to Old Man Bao's room to report the good news to his father.

"What? Mr. Su agreed? ”

The old man Bao was also excited, touched his eyes that had been roasted by the fire for many years and were almost blind, and the old man burst into tears: "That relationship is good, that relationship is good, our old Bao family is smoking on the ancestral grave."

By the way, you go and cut a piece of meat and make something delicious to celebrate at noon. ”

"Hello, Daddy!" Bao Erhei smiled and said, "No, I promised Mr. to go and do propaganda for the people of our Guide Mansion, and I'll talk about it when I come back." ”

Bao Erhei brought his father to the house and ran out in a hurry.

……

In the official office of the Guide Mansion, Qin Youde paced around the empty room with his hands behind his back.

After a while, his nephew Qin Jingfang ran over from outside sweating profusely, closed the door mysteriously as soon as he entered, and then quietly came to Qin Youde and said, "Uncle, I saw it." ”

"See, okay, what the hell is it?"

Qin Youde's eyes shrank slightly, and his heart became more and more curious.

I haven't felt this way for many years.

In this gambling fight with Su Baiyi, no matter from which angle he looks at whether he wins or loses, if he bets with ordinary people, he is already thinking about how to collect money at the moment.

But Su Baiyi is different after all, he has made too many strange things, and he seems to be frivolous and open-mouthed, but after thinking about it, he has not said anything. No matter how appalling the words are, they can still be convincing in the end.

Therefore, Qin Youde was not at ease, and let his nephew focus on Su Baiyi.

Last time, Su Baiyi said that he needed to prepare some things to verify that the atmosphere had great power, and he asked Qin Jingfang to stare at Su Baiyi, just to know what Su Baiyi had prepared.

The so-called knowing oneself and knowing one's opponent can survive a hundred battles.

After staring at Su Baiyi for a few days, I found that he had done a strange thing, that is, he ran to the shop on Xiaoqi Street to build weapons.

Could it be that this "weapon" is something that verifies the great power of the atmosphere?

Qin Youde aroused a strong curiosity, he must know what Su Baiyi created, but he couldn't blatantly ask for Bao Erhei, so he could only let his nephew watch it next to him.

The hard work paid off, and Qin Jingfang still got something after all.

He fumbled and took out two chapters of rice paper from his arms, put them on the table tremblingly and unfolded, and said: "Uncle, this is a picture that my nephew spent two taels of silver to let the guys in the Bao family's iron shop secretly get, and it is what Su Baiyi asked Bao Erhei to create."

The little nephew is ignorant and can't understand, uncle, look at it. ”

Qin Youde's results were drawn, and his brows furrowed slightly.

I don't know if I can understand it, but at least it's the first time I've seen a picture like this.

If you look closely, you can see that the detailed structure of the entire "weapon" is perfectly drawn, not only clearly delineated, but also able to quickly understand the intention of the painter.

Qin Youde looked at the drawings carefully for a while, and his mind gradually became heavy.

Although the details look extremely clear, if all the details are put together, it requires a strong spatial thinking ability to reassemble the details in the imaginary space.

He is a prefect anyway, with a lot of cultural heritage, and his quality in other aspects is not bad, and after thinking about it for about a quarter of an hour, he finally figured out what this thing was.

But this thing is two hollowed-out iron hemispheres, at most two handles on them, and one of them has something like a guy peeing on it.

How can this be?

Does this prove that the atmosphere has great power?

"I understand the picture, but I really can't figure out how to use this thing to prove that the atmosphere has great power!" Qin Youde thought about it for a long time, but he couldn't think of a reason.

"Uncle, do you want me to get the blacksmith of the Bao family over and ask?"

"Stupid!" Qin Youde scolded: "What time is it?" If there is a disturbance, I am the first to be unlucky, don't forget, I, Qin Youde, am the parent official of Guide Mansion, not a bandit. In the future, you should use some brains to do things, and don't give people a handle! ”

Qin Youde naturally couldn't guess that the picture he saw was the famous Ma Debao hemisphere.

In the not-too-distant future, about twenty-three years later, in the eighth year of Yongli, or the eleventh year of Shunzhi in the Qing Dynasty, on the other side of the world, in Regensburg of the Holy Roman Empire, Mayor Ma Debao conducted a cross-era experiment.

He put the two brass hemispheres together, put a rubber band in the middle, and after extracting some of the air in the sphere, the two copper balls were sucked together.

Then sixteen horses were found, each in groups of eight, and the two groups galloped against each other, and tried with all their strength to pull apart the two bronze balls that had been sucked together, like a tug-of-war.

But no matter how hard the sixteen horses worked, they couldn't pull the copper ball away.

Later, the number of horses gradually increased to thirty-two (there are also records of sixteen horses, which is not carefully verified. Only then did the copper ball "bang" away.

This experiment is not the first time that the existence of atmospheric pressure has been confirmed, but it is undeniable that this experiment is the first time to show the public the great power of pressure in the most simple, direct and acceptable way.

All Su Baiyi had to do was to advance this original experiment by twenty-three years, and then move its experimental site from Europe to Daming.
