The fierce battle lasted less than one night. The Turks who came to invade were annihilated by the whole army, and only smelly bodies were left on the battlefield. However, most of these were Turks.

The officers and men of Datang won the war with absolute superiority and successfully defended their homeland, which is the most proud thing as a soldier and the most proud thing of Datang people.

The border war has come to an end, and life on the border has temporarily returned to calm.

At the same time, Chang'an White Deer Academy.

The wind and snow all over the sky are floating in the air, and the snowflakes the size of your thumb are floating and scattering, permeated with the whole Academy.

After a while, the whole academy seemed to be covered with a layer of white cloth, like a paradise, which was yearning for.

Different from the border, the wind and snow in Chang'an is not so violent, but more gentle, just like a small hand touching.

Bursts of reading came from the classroom, like a sweet note, lingering for a long time.

Not far from the classroom, in a small house, several gray haired old people are sitting around a fire, with several tea cups beside them, which has a fairy temperament.

These are Ouyang Xun, Chu suiliang, Yu Shinan and Xue Ji.

Chu suiliang picked up the teacup next to him and took a sip: "Boshi, do you know what Fengzi is doing recently? Why don't you always come to the academy?"

Yu Shinan glanced at Chu suiliang: "how do I know? You should ask the boy."

"If I can find that boy, I'll ask you?"

The two old men said one sentence at a time.

Just then, there was a sound of stepping on the snow outside the door.

"Creak..."

Yu Shinan glanced back.

"It's Chumo. Come in and bake a fire to warm up."

Hearing this, Chumo throws the snow on his feet, opens the door and walks in. Wei Shuyu and Chang sun Chong followed behind.

"Thank you, Mr. Bosch."

After that, Chumo finds a place to sit down.

The other two also found a place for themselves.

Yu Shinan hands Chumo a tea cup: "Chumo, what are you doing recently? Why haven't you come to the Academy for so long?"

Cheng Chumo took the tea cup and said wearily, "we are working on the equipment of the textile mill, especially the power of the unmanned weaving machine connected to the waterwheel."

"What is this?"

Yu Shinan asked subconsciously.

Ask if you don't understand. It's human common sense.

Wei Shuyu, who was sitting on the side, interrupted: "listen to Fengzi. This unmanned textile car is realized in a physical way. No one can spin automatically. I don't know exactly."

"What's the connection between this water tanker?"

Wei Shuyu was about to speak. His eldest son rushed to pull him out, gave him a look and motioned me to say it. Then, before the other party could speak, he said: "Feng Zi said, that is to lay two hard piles beside the bank where the water flow is very rapid. The upper half of the big wheel is higher than the bank, and the lower half is immersed in the water and can rotate freely. There are bamboo tubes obliquely on the water receiving plate outside the spoke of the big wheel, and there is a sink near the water tank on the bank. When the big wheel is excited by the water plate, the wheel rotates, and the water tank is filled with water..."

"Stop, stop, stop."

Before Chang sun Chong finished, Ouyang Xiu interrupted him.

The old man really can't stand it. This guy doesn't finish talking. He's full of long speeches. The whole thing that others don't understand is more wordy than women.

Ouyang Xiu glanced at the three: "I ask you, you just kept saying Fengzi, where are Fengzi people? Where are they?"

"Isn't Feng Zi taking care of cotton at home?"

Wei Shuyu is a little confused.

Isn't that what everyone knows?

"You know a fart?"

Chumo glances at Wei Shuyu: "Feng Zi is not only making cotton at home recently, but also making firearms."

"Firearms?"

Yu Shinan frowned: "Chumo, how do you know?"

Chumo smiled with a mysterious look: "my father and Fengzi went up the mountain that day and saw that boy made a lot of weapons. Most importantly, there was a thing called fire gun. Listen to my father, although it was a little loud, it was powerful. It was said that there was no problem killing birds."

After hearing this, Yu Shinan's eyebrows wrinkled deeper and he could hardly see his eyes.

He glanced at Chu suiliang, Ouyang Xiu and Xue Ji and winked.

The three immediately understand that this is to continue the process of Chumo.

"Chumo, is there anything else Fengzi can do besides doing these things recently?"

Chu suiliang forced himself to smile.

"Something else?"

Cheng Chumo deliberately stroked his chin without beard: "what's more, this boy sells cotton padded clothes and buys dried flowers. It's said that this boy bought dozens of stones to buy flowers."

"What?"

Yu Shinan exclaimed, "buy flowers and buy dozens of stones?"

Chumo patted his thigh and said, "yes, you said this boy destroyed all the flowers of the emperor. If you don't say, he bought such dry flowers again. Isn't he idle?"

Yu Shinan looked at the two partners and made eye contact.

It seems that Feng Zi has been biased by Li Shimin again.
