Chapter 741

In the Mohist experimental field, I saw the selfless Mohist son walking with Princess Changle,

They are on the trail in the experimental field, playing an old game, flying kites!

It's spring at the moment. The wheat seedlings in the experimental field haven't grown yet. It's a good season to fly kites.

Merton held a swallow shaped kite and ran ahead suddenly. With the help of the wind, the kite with a long tail quickly soared up.

"Fly up! Fly up!" Changle, who had been in the palace for a long time, couldn't help cheering and jumping when she saw the kite flying.

"I want to play too..." Princess Jinyang raised her hands and looked forward to it.

Merton handed the kite to Princess Jinyang and instructed Princess Changle to fly a kite in person. They stood together. Merton jumped out a few witty words from time to time, which made Princess Changle laugh constantly.

Merton could not help but sigh that if Princess Jinyang had not been used as a light bulb, he would have dated Princess Changle.

"This is the sage's way of Tangtang Mozi?"

Suddenly, a dignified voice suddenly appeared behind them.

Merton and Princess Changle were startled. Looking back, they saw Li Shimin staring at them displeased. Behind him, the three brothers Li Chengqian were shrinking their heads like quails, and their kites had long fallen to the ground.

"Father!"

When Princess Changle saw Li Shimin beside her, she was ashamed and looked at a loss, but she didn't loosen the kite line in her hand.

As soon as Merton gritted his teeth, he stood in front of Princess Changle and bowed down and said, "this is the fault of Wei minister. Changle has been very dull in the palace for a long time. It happened that today is the ink technology exhibition. Wei minister wanted to ask Changle to go out of the Palace to relax."

When Changle heard the speech, he felt warm in his heart and quickly apologized: "the child is greedy for playing, and please punish his father and Emperor."

Li Shimin looked at the two people asking for forgiveness. He couldn't help but feel powerless. It's really a big mistake for women! He always knew that Merton and Princess Changle were flirting, but he couldn't catch it. Now he finally caught it. But when they were about to get married in half a month, what else could he say.

Li Shimin's face was bleak and said, "well, since you're out today, you'd better accompany me. I'm afraid you'll spend less and less time with your father and emperor in the future."

"Father! Look what you said, the child will always be your daughter!" Princess Changle said softly.

"Father, you still have your son!" Princess Jinyang came forward and hugged Li Shimin's thigh like a sweet little cotton padded jacket.

The father and daughter talked for a while, and Li Shimin slowly turned happy. Li Chengqian couldn't help but breathe a sigh of relief. They finally avoided one session.

"After going back, the three of you will write an article and give it to me based on the daily needs of the people!" without waiting for the three brothers to relax, Li Shimin's light sentence immediately made the three look bitter.

Li Zhi angrily denounced Merton with an exaggerated face. If it weren't for the fact that the Mohists invited sister Changle to play, they would have returned to the palace after watching the ink technology exhibition. Where would Li Shimin catch them.

He doesn't like to write articles. I'm afraid he'll have to rack his brains this time. I don't know how much brain power he spends.

Li Chengqian and Li Taike are not as simple as Li Zhi. They can't help but move in their hearts. Since Li Shimin asked them to write articles with the daily use of the people as the Tao, doesn't it mean that Li Shimin also agrees with Merton's theory that the daily use of the people is the Tao, and they can't help but turn their eyes to Merton.

"And you!" Li Shimin turned his head and stared at Merton with good intentions.

Merton was so brave that he said proudly, "please tell your majesty."

"Since you put forward that the daily use of the people is the way, I will let you use this concept to create something beneficial to the people all over the world, and based on the atmospheric pressure principle you spent a lot of time to solve today." Li Shimin sneered.

What he criticized most about Merton was the behavior of his black sheep. Today, Merton spent thousands of money just for an unknown atmospheric pressure, which made Li Shimin unhappy. Now he saw that Merton deviated from his good daughter Changle, and he was unhappy with Merton and couldn't help raising the idea of embarrassing Merton.

"Ah!" Merton was dumbfounded. Isn't a kill worth enough? Li Shimin asked him to make another one.

Seeing Merton's embarrassed look on his face, Chengqian and Li suddenly felt great in their hearts. The resentment originally caused by writing the article was immediately swept away.

Suddenly, Merton looked at the kite line in Changle's hand. At the other end of the line, a kite was still spreading its wings in the wind. Merton had an idea and said, "wind! Yes, it's the wind. Weichen thought that the common wind is caused by atmospheric pressure."

"Wind?" everyone was stunned. Naturally, the wind is well known, but everyone knows nothing about how the wind is formed.

"The wind is caused by atmospheric pressure. What's the explanation?" Li Shimin said with great interest. All the people can feel the wind all the time, but they don't have a trace of understanding. Until Merton put forward the idea of oxygen and air, they understand that they are not surrounded by nothing, but wrapped by air.

Merton stretched out his arms, and the strong wind blew Merton's clothes away. He said proudly, "since the air has weight, there will be pressure. The wind is like running water. There must be a force to promote the air flow, and this force must be atmospheric pressure."

People can't help thinking. Merton uses water as an example to compare the wind. It can be said that it is very appropriate. The principle of water flow immediately cares about the origin of the wind. Moreover, water can carry boats, wind can blow kites and float hot-air balloons.

"So this is the wind!" Li Shimin said with emotion. He couldn't help feeling enlightened.

Li Tai's eyes suddenly lit up. Although the air pressure is the knowledge of Mohism, the wind is a natural phenomenon in heaven and earth. Naturally, it can be included in kuodi chronicles. In this way, after his kuodi chronicles cracked the cloud, he cracked the wind again, which is a surprise.

"So it is!" Li Chengqian also suddenly realized that he could not help looking at Merton with surprised eyes. As Merton said, what the Mohists studied was a phenomenon hidden between heaven and earth.

"Even if you're right, my request is to let you create a thing that is beneficial to the people all over the world. What's the use for the world if you break the wind?" Li Shimin didn't let Merton go so easily.

"Of course, it's useful. In the future, if we can measure the wind speed and direction according to the air pressure and direction of the wind, prevent coastal storms in advance, protect the safety of fishermen at sea, and even predict the direction of clouds and predict the weather in a few days," Morton said.

Li Shimin couldn't help breathing and couldn't wait to ask, "can Mohism make it?"

Merton suddenly lost his momentum, shook his head and said, "at present, it is impossible. I'm afraid the use of air pressure must be like Mohist's optics. Without millennium development, it is impossible to achieve with the help of specific artifacts. However, once optics meets glass, it plays an unimaginable role."

The people suddenly sighed with disappointment. The millennium is too long. I'm afraid they can't see it.
