Li Er was stunned when he heard the speech. Then he reached out his hand on Li forgetful\'s head and knocked a record of chestnuts.

"Ouch!" Li forgot to worry. Unexpectedly, Li Er actually started beating people. Out of guard, he was knocked out of his head and howled miserably.

"What kind of gambling? If you don\'t learn well at a young age and want to gamble with people all day, what\'s the style?" Li Er glanced at Li forgetful and scolded him impolitely.

Li Qieyou was speechless, but he couldn\'t speak.

When he was about to withdraw, Li Er turned to Fang Xuanling and said, "Fang Gong, do you think it\'s possible to pull the bronze ball away by pulling the horse? No, if you and my monarchs and ministers gamble?"

Li Er\'s words immediately made Li forget his worries as if he had been struck by lightning

Nima, Li Er, what about your integrity?

Just then Weiguang scolded himself and turned around to gamble with Fang Xuanling? Shame, no?

He completely forgot that he wanted to bet with Li Er, but he didn\'t have any good intentions. He clearly wanted to take advantage of Li Er.

Li Er is not a fool. How can he do what he wants.

The two ends of the copper ball were soon fixed on the horse. Under the attention of the people, the driver whipped the horse and urged the horse to start working.

On both sides of the bronze ball, there is a strong horse. Under the control of the driver, the horse immediately pushes forward. The rope was quickly stretched straight, and the copper ball was pulled into the air.

However, no matter how hard the two horses pulled, they even trampled the grass under their hoofs, but the copper ball did not move.

This scene surprised everyone\'s chin.

Before, Cheng Yaojin, Yuchi Jingde and others couldn\'t open the copper ball, which was already somewhat surprising. But unexpectedly, he couldn\'t even pull away two horses.

Even though Cheng Yaojin and Yuchi Jingde are famous generals and powerful, they can\'t compete with horses.

The word horsepower is often said in later generations.

Of course, the horsepower of later generations refers to power, not the power of horses.

But Li also watched a video of someone tug of war with a horse.

Eighteen strong adult men competed with a Belgian Working horse, but they didn\'t have the strength to fight back. They were easily dragged away by the Belgian Working horse

Although the horse Li forgets to worry about is not as strong as the Belgian Working horse, its strength is at least equivalent to that of six or seven adult men.

Seeing the two horses pulling the bronze ball, Hou Junji\'s face became more and more ugly.

The onlookers were even more talkative and felt that the scene in front of them was really incredible.

Li forgot to worry and stopped the driver with satisfaction. He snapped his fingers smartly and signaled Niu Wu to lead two more horses.

Four horses, naturally, could not shake the bronze ball, but the eyes of Li Er and others were about to stare down.

When the horses were added to eight, there was still no response. People even began to wonder whether the copper ball was replaced by a dead copper ball by Li forgetful.

Under the driver\'s desperate urging, the horses pulling the copper ball began to breathe heavily, and the horses were wet and full of sweat.

When Li forgot to worry and asked the horse and the driver to stop to drink water and rest, everyone was numb.

"Ziyou, tell me the truth, you really don\'t have hands and feet on this copper ball?" Li Er also began to doubt whether the copper ball had been replaced. He called Li forgetful to his side and asked in a low voice.

Li forgot to worry and replied with a smile: "uncle, don\'t be impatient. The copper ball will be separated. As I said before, the atmospheric pressure is very high, but there is also a limit. As long as the number of horses is continuously increased, it can be pulled away. This is the knowledge of atmospheric pressure taught by the master."

Li Er sighed: "wonderful, it\'s really wonderful! It\'s not bad that the Taoist ancestor taught you the knowledge! Ziyou, what knowledge did the Taoist ancestor teach you? Is there anything beneficial to our Tang Dynasty?"

Li forgot his worries and was speechless. Li Er was so utilitarian.

"Uncle, all this knowledge is good for my Tang Dynasty. How can you think that the knowledge taught by the master will be useless?"

Li Er quickly whispered, "no, I don\'t mean that. I mean, master, can you teach me the knowledge that can be used for my Tang dynasty like a four-wheel carriage, waterwheel, horseshoe and fine steel crossbow."

Li forgot to worry and said with a smile, "uncle, in fact, I don\'t say it. You should also guess that the guru taught me, including the four-wheel carriage and the waterwheel."

Hearing the speech, Li Er slapped him: "sure enough, I heard you admit that the Taoist ancestor was your master some time ago. I guessed it vaguely. Ha ha, the old ancestor can accept you as a disciple, but Ziyou\'s blessing is also mine and the blessing of the Tang Dynasty!"

Before the hemispheric experiment was completed, Li Er had no doubt that Li Qieyou was a disciple of Lao Tzu.

"Uncle, I\'m flattered." Li forgot to worry and was overjoyed when he could deceive Li Er. He quickly controlled his expression so as not to laugh.

After the driver and the horse rested, the experiment continued again.

The number of horses was increasing, ten, twelve, fourteen... Until it was increased to sixteen horses. Like the madeborg hemispheric experiment in history, the copper ball finally made a loud noise and was pulled away by the huge traction of the horses.

Li Er and a group of officials, without waiting for Li forgetful to speak, immediately gathered around the past, picked up the two hollow hemispheres and looked carefully.

"Zhiniang thief, it\'s really the same as the previous two hemispheres. I used to change Ziyou into a solid one." Cheng Yaojin shouted holding a hemisphere.

Others try to reunite the two hemispheres, but easily separate them.

Without the existence of atmospheric pressure, the hemispheres will not be pressed together.

Li Qieyou was very satisfied with the experimental results. He raised his hemisphere and said to the people, "Your Majesty, this is the best proof of the existence of atmospheric pressure. When the air in the copper ball is pumped away, the external air will press it tightly. If there was no atmospheric pressure in our human body, we would have been crushed to death by the air."

In the face of this iron fact, some people no longer doubt Li forgetful\'s words.

Even many people, still palpitating, reached out and touched the air above their heads, as if they were worried that one day, they would suddenly be crushed to death by the air falling from the sky.

Li Er was very interested, and even went to battle in person. Under the guidance of Li forgetful, he repeated a hemispheric experiment.

People have no doubt about this.

Cheng Yaojin and a group of dandies laughed licentiously at the result.

They were naturally happy to win 10000 horses and dozens of beautiful maidservants for no reason.

Hou Junji and others turned away without saying a word.

Li forgot to worry about what to say, but saw several figures in the crowd. Without saying a word, he bowed down in front of him.

"I\'ll pay a visit to Shizu..."
