Chapter 1252

"Men don't have a good thing!"

Princess Changle looked at her husband and brother, secretly calculating East Turk and Xue yantuo, and said angrily.

After a long time of whispering, Li Chengqian got up happily. With the plan of the memorial by the agent, there will only be one winner in the grassland war, that is Datang.

As for whether the East Turks would like to be Tang's agent, Li Chengqian has no doubt. After all, the East Turk tribe, which is facing life and death, has no choice at all.

"Let's go. I haven't seen Martha and mertan in the palace for a long time. I miss them very much." Li Chengqian solved the problem. Then he remembered his nephew and niece and got up.

Princess Changle smiled bitterly and said, "those two living treasures are very naughty now!"

At the thought of her own children, Princess Changle had a headache. These two living treasures made the ink house jump every day.

The three got up and went to the third floor villa. Before they reached the place, they heard a loud noise from a distance.

"Higher, higher!"

The excited voice of Martha kept coming. Merton came forward and saw her blood pressure rise. She saw Martha sitting on a swing, and Wu Meiniang behind her kept throwing it higher.

There was also a swing on one side, on which sat a small mertan, pushed behind by Uncle Li Zhi, laughing happily.

"This crazy girl!" Princess Changle was so angry that she didn't know whether to say Wu Meiniang or Mosha.

Li Chengqian also shook his head and smiled bitterly. As a royal nobleman, where can he play so crazy.

"I'll catch them!" Princess Changle said angrily. In the eyes of a mother, such behavior is too dangerous and not a lady.

"Wait!" suddenly Merton's eyes lit up, stopped Princess Changle who wanted to come forward, and stared at her sister and brother sitting on the swing.

"Master!"

Looking at the appearance of Shifu and Shiniang, Wu Meiniang felt empty and wanted to stop.

"Keep pushing!"

Merton waved his big hand and said expressionless. Wu Meiniang didn't know whether master was angry or not, so she had to harden her head and continue to push.

When Li Zhi saw Wu Meiniang punished, the man's courage immediately rushed up and said proudly, "brother-in-law, it's not Meiniang's fault. The ninth brother asked Mosa Motan to sit on the swing."

"In that case, if your brother-in-law asks you to sit on the swing, will you sit?" Merton raised his eyebrows.

"My brother-in-law has a life. How dare the ninth brother not obey?" Li Zhi said with a smile.

Li Zhi stretched out his hand to hold Motan down, jumped and sat on the swing. He was already a 15-year-old boy. He didn't need to be pushed. When he kicked with his feet, the swing swung up.

"Master, I also admit punishment!" Wu Meiniang, unwilling to show weakness, took Martha down and sat on the swing.

"Admit punishment?" Li Zhi frowned. He just sat for a long time. What punishment is this.

Wu Meiniang gave Li Zhi a blank look. She knows her master best. After making a mistake, she will let you sit on the swing easily. This swing must be hard to sit. She didn't see that two ungrateful white eyed wolves, Mosha and mertan, had already secretly run away.

The breeze is warm, and the sun turns into a little circle through the small holes on the ground through the leaves. In the shade of the tree, a handsome young man and a graceful young girl swing side by side. What a poetic thing it is.

Facts have proved that nothing is a happy thing to do for a long time. Swinging is a beautiful thing. However, continuous swinging is a very hard thing. Even if the two people have no strength to swing by themselves, Merton ignored it and even sent two Mohist children to push them behind.

"You start swinging at the same time, one higher and one lower."

"Now start counting a quarter of an hour and count the number of swings in your heart."

"You two hold on to the swing and fall freely from the highest point this time."

…………………………

Merton's continuous urging and the variety of swing methods make the destruction of this warmth disappear.

Wu Meiniang felt trembling all over. She felt that she would never like to swing again in her life, but the master didn't stop. She still insisted, and Li Zhi didn't want to lose face in front of her sweetheart,

Slowly, everyone's expression began to be dignified. Originally, everyone thought that Merton was punishing them. Soon they saw something wrong. Merton seemed to find something on the swing.

"Brother Prince, do you see anything?" Princess Changle knew her husband best and knew that her husband had an epiphany, but she didn't know why.

Li Chengqian nodded seriously and said, "look carefully. Li Zhi and Wu Meiniang began to swing at the same time. No matter how high or low they swing, they will coincide where they started at the same time."

When Princess Changle looked carefully, she was surprised and said, "really?"

She found that two people swing at the same time, one high and the other low. Naturally, there will be overlapping times. However, the overlapping place is always the same, and it happens to be the place where they start at the same time.

"In addition, no matter how fast or slow they swing, they go back and forth the same times in a quarter of an hour." Li Chengqian took a deep breath.

"What's the use of this?" Princess Changle didn't understand.

"Time!" Li Chengqian said word by word, "that is to say, within a quarter of an hour, whether adults or children, whether they swing high or low, the number of swings back and forth is the same. I feel brother Mo has found a way to accurately time."

Merton said just now that neither the watch nor the sundial nor even the four side clock of Mohism touched the essence of time, because they could not accurately determine the minimum time. Now, Merton seems to have achieved the accurate minimum time, that is, the time of a swing.

"Seven thousand two hundred swings in one hour, three thousand six hundred in half an hour, which is a very magical discovery." Merton looked at the record in his hand and raised his eyebrows.

Li Chengqian nodded slightly. The lunar calendar year is 360 days. Not long ago, the ancestor of mathematics calculated that the circumference is 360 degrees, and the hollow sundial with four clocks is also round. I'm afraid it's not just a coincidence.

"Well, you come down!" Merton looked at the two who were gritting their teeth and insisted, and mercifully let them go.

They were relieved and hurried from the swing. I'm off. Just moved to the ground, I felt my legs and feet soft and almost didn't collapse on the ground.

The two looked at each other. In the eyes of the world, it was a good thing to swing, especially with their sweetheart. However, this time, they subverted their ideas. Even if a good thing persisted for a long time, it was so painful.

Even love!
