Physics

Seeing that his sister cared so much about the farmer's land, Ye Tian had no choice but to follow.

Hu Liena hesitated but then took off her expensive shoes, followed Ye Tian with bare feet, and also went to the field.

Facing Bibi Dong's inquiry, the farmer who was plowing the land stopped what he was doing, raised his head, and asked, "You are..."?

"She is my sister." Ye Tian, ​​who also followed up, explained.

After the farmer looked up and saw Ye Tian's appearance, he was shocked:

"Oh, young master, why did you come to the field? You shouldn't have come to this messy place..."

Ye Tian interrupted the farmer's voice and said with a chuckle :

"Don't forget, I personally taught and promoted all the farming techniques. It's not that I haven't been to the farmland before. In addition, I don't think it's dirty in this soil. It's also a joy in life."

Farmer also showed a look of gratitude looking at Ye Tian.

Last year, there was a tsunami at the seaside destroying the fields and crops, and many people died of starvation.

Only they are safe from disaster.

It is all thanks to Master Ye Tian that the farmers on the farm can live a warm and well-fed life.

The farmer turned to look at Bibi Dong again, the beauty in front of him was actually Ye Tian's sister, she was really a fairy in the world.

Having a gentle smile she is worthy of being part of the same family as Young Master Ye Tian, ​​and she had no arrogance at all.

Since she is Ye Tian's sister, there is nothing to hide about the plowing issue. The farmer explained bluntly,

"Our plowing speed is not due to the strength of the cattle."

"The secret is hidden in the plow share."

The farmer smiled patting the curved plowshare.

Bibi Dong bent down to check, and quickly discovered the clues on the plowshare:

"This plowshare is curved."

"Yes." The one who spoke was Chen Jian, the manager of the farm as he explained to Bibi Dong: "This is called the Quyuan plow, and it was invented by Master Ye Tian. Changing the degree of curvature of the plowshare can save energy to the greatest extent. Such a plowhead can plow the land much faster, and it can plow deeper."

After hearing Chen Jian's explanation, Bibi Dong looked at Ye Tian in surprise: "I never thought that you not only have business talent, but you also have a great talent in agriculture."

Ye Tian smiled slightly but did not speak, this is just a product that he imitated from Earth

(Quyuan Plow is a Copper/Bronze Plough used in China since Tang Dynasty)

and it has no technical content.

After seeing Quyuan plow Hu Liena couldn't help asking: "There seems to be no difference between a straight plow and a curved plow. Why can you save energy by using a curved plow?"

Chen Jian, the manager of the farm, had a wrinkled face. With a smile on his face, he explained:

"Some differences are hard to see on the surface, but in fact, the difference is quite big.

" Does it take the same amount of strength to lift two different things?"

"Obviously different." Hu Liena blurted out.

Chen Jian smiled lightly and said, "Quyuan is also the same. According to what Master Ye Tian said, the role of force is different, and the useful work it does is also different."

Hu Liena was surprised, her eyes froze slightly:

" Force? What is this term?"

"Master Ye Tian said that this is called "Physics", but I only know a little bit about it."

Chen Jian said.

"Physics?" Hearing this term, even Bibi Dong became interested and looked at Ye Tian with beautiful eyes.

Ye Tian said seriously: "Physics is the principle of all things. I can't explain it clearly to you now.

But a year ago, when I had nothing to do, I wrote a few textbooks about physics. The textbooks are in the villa, sister, you can watch it if you have time."

Of course, he would not say that the textbook was not written by himself but a gift given to him by the system.

"About the theory of all things?"

Bibi Dong nodded slightly, remembering the word physics in her heart, and she must read it carefully when she goes back.

Afterward, a hint of probing flashed in Bibi Dong's heart, she stared at Ye Tian

"Brother, why would you hide such a useful tool, and not let outsiders know about it?

" Such a useful tool should be popularized so that more farmers can use it, so as to maximize its benefits."

"It seems that my sister is really poor"

He thought

Although keeping Quyuan's secret can indeed make more money.

But this kind of money is not what Ye Tian wants to earn.

What's more its secret is too simple.

It is so simple that you only need to glance at it, remember it, and then copy it.

So instead of keeping it a secret, it is better to announce it openly and buy people's hearts.

This answer made Bibi Dong's eyes flash with surprise, she never thought that Ye Tian was not only smart but also very righteous.

She has been the pope for many years, but she rarely sees such a moral person as Ye Tian.

"You've already promoted it?" Bibi Dong suppressed the surprise in her heart and asked.

Ye Tian sighed softly: "It doesn't count. Only one-third of the farmers on the entire coast of the East China Sea are using my Quyuan."

Hu Liena on the side was surprised: "Since it can improve efficiency, why? Only one-third of the peasants use it?"

Ye Tian explained: "Everything has to go through a process, and I am not the ruler of the East China Sea, so I cannot force the peasants to use the plow."

"That's how it is." Hu Liena showed regret:

"Even in such a small place by the East China Sea, it is so difficult to promote it. If it is to be promoted to the whole mainland, I don't know how many years it will take."

"Yes." Chen Jian deeply agreed: "Such an easy-to-use tool, It is really a pity that it cannot be promoted to the whole continent."

Bibi Dong smiled and said: "What if there is a force behind it? For example, the two empires, or the Spirit Palace?"

Ye Tian sneered nasally when he heard his sister's words:

"How is this possible for the two empires and the Spirit Palace to pay attention to such a small place on the coast of the East China Sea?

To accurately find out about the plow's invention and promote it is no different from finding a needle in a haystack!"

Hearing this, Hu Liena covered her mouth and let out a smile.

Ye Tian stared at Hu Liena's side face: "Sister Nana, what are you laughing at?"

"Huh? Am I smiling?"

Hu Liena refused to admit it but thought jokingly.

This guy Ye Tian actually said in front of the Pope that Spirit Hall would not notice him.

It was so funny.

Suddenly, her attention was attracted by the cart on the road.

The cart was full of a bunch of round things with yellow skin.

This was a plant she had never seen before, she turned around and asked Ye Tian: "Brother, what is that round plant?"

"It's a potato." Ye Tian had nothing to hide and said bluntly.

"Potatoes?"

Bibi Dong was also attracted by this term, she had never heard of such a crop.

Seeing Bibi Dong and Hu Liena's doubts, Chen Jian's wrinkled face suddenly brightened, and he explained to Bibi Dong:

"Miss, you haven't been home for several years, so it's normal that you don't know what a potato is. Master Tian found a crop in the deep mountains, with a yield of up to 5,000 catties per mu.

[1 Catty equals 500 grams (approx)

1 mu equals 0.165 acres or 666.5 sq. meters]
