Chapter 259 Desire

"Bang……!!!"

One day in late February, the day after Mr. Guishan Yang Shi brought the other two direct disciples of Cheng Men to Beijing, at noon, in front of the Xuande Tower, there was a dull loud noise, like a rolling spring thunder, followed by exclamations and shouts like a storm.

The twenty strong horses that suddenly broke free were startled by the shouting and galloped non-stop. Two teams of ten horses each pulled a hollow copper bowl and kept clanging and clattering on the Imperial Street. They ran several hundred steps away before being stopped by the obstacles set up by the imperial guards.

At the same time, on the Xuande Tower, the two imperial concubines, dozens of important ministers and great scholars, and more than a hundred low-ranking civil and military attendants, including the armored and armed imperial guards, who were sitting together with Emperor Zhao, all lost their composure and looked around in amazement from the railings.

That's right, the 'air pressure experiment' that had been delayed again and again was finally completed, and in a way that was so intuitive that it surprised everyone... It was a classic hemisphere experiment, with two hemispherical copper bowls, the air inside was drained, and the inside became a vacuum state, and the power of atmospheric pressure was undoubtedly demonstrated under the power of the horse.

By the way, this experiment did have some twists and turns in preparation.

For example, Emperor Zhao initially thought that the biggest technical challenge he would face was the sealing of the contact surface between the two hemispheres, and even prepared a fish bladder. But later he found that as long as he was careful in casting and made the contact surface smooth, there was actually nothing wrong with it...

The real trouble is how to extract the air from the hemisphere.

This problem was what Zhao Jiu and Chen Gui spent a lot of time and effort on, but you know what, Emperor Zhao actually regained his pride as an engineering student and finally solved it.

After encountering this problem, Zhao Guanjia's first reaction was the water pressure well he used when he was a child, so he thought of making a hole directly on the ball and installing a simple piston pump like the one used in the water pressure well. However, the piston pump is not so easy to make... First, he found that the leather and iron castings in his memory were not airtight, so he went back to basics and changed to filling water into the ball first, and then using the natural gas tightness of water to pump the water out to create a vacuum; but just filling water was not enough, because no one had the strength to pump out all the water, so he added a lever; later he found that when it came to the last and most critical point, the joint between the pump body and the copper ball was always disconnected, so he had no choice but to go back to the casting process and cast the pump on the ball from the beginning; finally he found that the water was pumped out and the airtightness was insufficient, so he had no choice but to add an iron ball under the cowhide to act as a piston.

All in all, it was equivalent to Zhao Guanjia reviewing high school physics again, and also equivalent to "inventing" a water pressure well from scratch...it was indeed a water pressure well...but no matter what, with the excellent physical design of this young engineering expert and Chen Gui's excellent technical practice, this thing was finally made.

The time spent on inventing the water pressure well and preparing for the experiment was about ten days, and the finished product experiment in the Yuetai camp in the suburbs took another ten days... However, the time point of this plan was basically before the New Year!

In other words, the official had made preparations long before the bet was made, and he was fully confident shortly after the bet was made.

However, in order to create momentum, he took the initiative to delay the time, and kept delaying it until now. Fortunately, the effect was obvious.

Moreover, scholars and Confucian scholars who knew a little about Taoism and Yuanxue actually knew that the loud noise only verified the description of Yuanxue by Lu Gongxiang that Qi is like water, but it did not prove that Yuanxue had grasped the truth on the fundamental issue of "Qi"; from another perspective, it could not prove that the theories of other Taoists were wrong, and it could only be said that it proved that Hu Anguo, the main opponent of Yuanxue in the capital, had made a slight mistake on the issue of "Qi".

As for other schools, such as the orthodox Cheng school of Taoism, Yang Shi and two direct disciples of Cheng school arrived in the capital, they just made a couplet and then hurriedly faced the experiment.

However, thanks to Emperor Zhao's constant hype and procrastination, this loud noise gave all those who did not study, and even many who did study, an illusion - that is, Yuanxue won over Taoism!

Back to the present, Lv Benzhong, who had seen the demonstration in Yuetai Camp before, regardless of his status, stood directly on the side of the Imperial Street under the Xuande Building and showed the re-assembled copper ball to the people on the roadside again. He also pulled it apart at will to show it, and explained the reason behind it tirelessly... It turns out that when there is air inside the ball, there is no air pressure outside. Now that there is no air inside, it has become a vacuum, and the air outside presses down on the copper ball from the outside. The twenty horses are competing to see who has more strength against the invisible and intangible but actual air pressing on the outside of the copper ball.

Seeing this scene, Zhao Ding, who was also surprised, stood up from the upstairs, turned around and bowed to the prime minister Lu Haowen beside him to congratulate him, congratulating the prime minister on his great progress in knowledge, and also congratulating Prime Minister Lu for being able to make such a big fuss when he was very old and almost faded out of politics.

And it’s some kind of big move with unlimited potential.

After all, one should establish virtue, make achievements, and make statements... Prime Minister Lu Gong has already made achievements, and now he wants to make statements. When the time comes, he will brag about his virtues. Who knows, one day while he is still alive, he may have achieved all three, and become a true saint of the time.

Therefore, to put it bluntly, anyone in the Xuande Tower today has reason to envy Prime Minister Lu's luck and achievements.

However, he didn't know if it was an illusion, but Zhao Ding always felt that Lu Gongxiang, who was about to become a saint, was a little dazed, as if he was shocked by the result of this "practice" like everyone else.
