Datang's free and easy concubine

Chapter 312 Experiment

"Nonsense, how could two iron balls, one big and one small, hit the ground at the same time? The big iron ball is heavier, so of course it hits the ground first!" Li Shimin sneered.

Li Zhi scratched his head and said, "Father, this son-in-law thought the same way at first, and everyone thought so. Later, my brother-in-law took us to verify it for myself. We loosened two iron balls at the same time from a high place, and the result was one big and one small. The two iron balls actually landed at the same time!"

Empress Changsun exclaimed softly: "Did they really land at the same time?"

Li Shimin said decisively: "This is impossible!"

"Really, father, it's true. My son saw it with his own eyes. If you don't believe me, ask fourth brother, fourth brother also saw it with his own eyes!" Li Zhi insisted.

Empress Changsun turned her eyes and said with a smile: "If Your Majesty doesn't believe it, it's not easy. Let's verify it, okay?"

Li Shimin snorted: "Verify it and verify it, I don't believe it, two different iron balls can land on the ground at the same time!"

"Go, find two iron balls of different sizes!"

"It must be solid!" Li Zhi did not forget to enjoin.

Li Shimin, Empress Changsun, and Li Zhi stood in front of the tall building. Even Princess Changle and Princess Yuzhang rushed over after hearing about it. Obviously they were also very curious about it.

Two iron balls fell from the sky, and everyone stared at them without blinking.

"Yeah! They landed at the same time, father and mother, did you see that they landed at the same time!" Li Zhi jumped up happily.

Empress Changsun exclaimed, "It's unbelievable that they actually landed at the same time!"

Unwilling to give up, Li Shimin asked people to try again several times, and had to admit bitterly that the two iron balls, one big and one small, did land at the same time.

"Why is this?" Li Shimin was puzzled.

Li Zhi beamed and began to explain.

Li Shimin and Empress Changsun were fascinated by what they heard.

"My brother-in-law also said that we will talk about atmospheric pressure in two days. He said that although we can't feel it, we are actually surrounded by air, and the air also has pressure. He also wants to do a large-scale experiment and send out many invitations. Please go to watch the ceremony, Queen Mother, this is your invitation card!" Li Zhi said excitedly.

It is said that it was a large-scale experiment, and it is exciting to think about it.

After handing over the invitation to the queen mother, Li Zhi suddenly stared at him with burning eyes, and when he turned his head slightly, he found that the eyes came from his father.

At this moment, Li Zhi suddenly remembered that only the queen mother had an invitation card, but the emperor father did not!

Brother-in-law will not forget, right?

No, it must be on purpose!

Really, so exciting!

Li Zhi swallowed nervously, shrinking his neck like an ostrich.

When Li Shimin saw Li Zhi's appearance, he knew that Su Cheng hadn't prepared an invitation for him. He was so depressed that he almost vomited blood!

Since he was going to watch the ceremony, how could he, the emperor, be missing?

In the end, Su Cheng didn't even give him the emperor's invitation!

Be stingy!

He was really curious about what experiment Su Cheng was going to conduct, and he invited so many people to watch the ceremony.

But, thinking that Su Cheng didn't invite him at all, can he go?

Of course, no one would dare to push him out after he went, but, does Li Shimin want to lose face?

Empress Changsun was very hesitant holding the invitation. Of course she wanted to go, but the emperor didn't have an invitation.

She complained a lot to Su Cheng in her heart, what a bastard, this is a good opportunity to ease the relationship with the emperor, but Su Cheng refused to give the emperor an invitation.

Where does this put the emperor's face?

Li Shimin snorted angrily: "If the queen has time, go and see what that kid is up to. I'm busy!"

The people in Chang'an didn't understand what the experiment was, so this incident didn't cause any repercussions in Chang'an, but on that day, Su Cheng's village was very lively.

Almost all the nobles from Chang'an came, and some of them were shameless if they didn't receive the invitation, such as Prince Li Chengqian and Du He.

They have also been paying attention to Su Cheng, but they are not interested in so-called mathematics. Is that thing useful for governing the country?

When he knew that Li Tai and Li Zhi came to study with Su Cheng, Li Chengqian even sneered, Li Tai really didn't even want the face of the prince!

Li Tai, a prince, can be shameless, but he, a prince, must be shameless!

But he still came today, not because he was interested in Su Cheng's experiment, but because all the nobles in Chang'an City came!

But the emperor did not come, nor did the eldest grandson empress.

Empress Changsun suddenly felt unwell, so she was unable to come.

Su Cheng didn't care, Li Zhi and Li Tai also came, but he was slightly disappointed that Princess Changle didn't come.

"Hey, today's tea is unusual!" Changsun Wuji said in surprise.

Cheng Yaojin picked up the tea and drank it, smacked his lips and said, "Mmm, it's quite fragrant!"

"It's really a cow chewing peonies!" Li Ji shook his head and said with emotion.

"Su boy, Su boy, what kind of tea is this?" Yu Chigong asked loudly.

"This is the top quality Mingqian Longjing. It's so rare that it doesn't even exist in the palace. If anyone can pull this copper ball away today, I'll give him a catty of Mingqian Longjing!" Su Cheng said with a smile as he tossed the two hemispheres with both hands. .

Everyone asked curiously: "Isn't this already separated? What are you doing, do you want to stick it together?"

Su Cheng explained with a smile: "It's not glued, it's closed, and then the air inside is pumped out."

Everyone gathered around and watched Su Cheng tinkering with curiosity.

"Okay!" Su Cheng clapped his hands and smiled.

Cheng Yaojin asked suspiciously: "That's it?"

Su Cheng nodded and said: "That's it, whoever can pull it away, I will give him a catty of Mingqian Longjing!"

The best Mingqian Longjing will be given away as soon as you pull it away?Who can't pull this off?

Cheng Yaojin immediately laughed and said, "I'll do it! I'll do it!"

Yuchi Gong shouted loudly: "You go, I'll come, I'm strong!"

Su Cheng laughed and said: "No need to grab it, no need to grab it, anyone can try it, as long as I can pull it away, I will give away a catty of Mingqian Longjing, and I will never break my promise!"

Even the prudent Fang Xuanling and Wei Zheng were very moved. This Mingqian Longjing is really attractive.

Cheng Yaojin snatched the copper ball, and then started to pull it with both hands, but the copper ball did not move at all.

I still don't believe it!Cheng Yaojin yelled loudly and exerted all his strength, his face turned purple, but there was still no sign of the copper ball being opened.

Yu Chigong couldn't help laughing and said: "Old Devil Cheng, what's the matter with you? What's wrong with not eating enough? Did you use all your strength on women? Hahaha!"

"Come on, I don't believe you can pull it away!" Cheng Yaojin threw the copper ball to Yuchi Baolin, he felt that this thing was really evil.

Yu Chigong took the copper ball, looked around and laughed, "Let me show you what strength is!"
