Datang: You Can't Imagine the Happiness of the Prince

"Wan family boy, this old man has been following you for three days and intends to take a good look at you!"

"Li Shangshu, what can the younger generation see?"

"Wanjia boy, you are the biggest new thing in Chang'an City recently, and the old man is inevitably curious."

Wan Kuan waved his hand and smiled: "Li Shangshu has won the award, you are the military god of the Tang Dynasty, why do you like to join in the fun so much?"

"This is not lively, the old man knew from the first sight that you are not in the pool."

Li Jing's eyes lit up: "How about learning martial arts from this old man?"

Wan Kuan waved his hand: "It's boring to practice martial arts, the juniors don't want to practice the five and three rough!"

"You boy!"

Li Jing was a little unhappy: "You kid has a big body and a big three. This old man sees that you are not weak. If you learn some martial arts, it will be of great benefit in the future!"

"The bravery of a man, even if you don't learn it!"

Wan Kuan raised Erlang's legs.

"you..."

Li Jing's beard fluttered.

"You kid, you are so arrogant.

Do you know how many people want to take the old husband as their teacher?"

"Li Shangshu, the old man doesn't mention his bravery back then, he is afraid of young men in boxing.

Besides, even if you fight alone, no matter how powerful it is, it won't affect the overall situation!"

Li Jing was dumbfounded by what Wan Kuan said, and he never thought that this kid Wan Kuan would answer like this.

In fact, the reason why Wan Kuan was reluctant to learn was mainly because he was afraid of trouble.

If you have that time, it would be nice to hold hands with Wu Shun'er.

Li Jing pondered for a while, then continued: "Son, you don't like the bravery of ordinary people, how about leading troops to fight?"

Wan Kuan looked strange, what happened to this Li Jing today? Wan Kuan leaned in front of Li Jing and said, "Son, what happened to you today, why do you have to accept this junior as an apprentice? Is this junior talented and unique? the genius"

After listening to Li Jing, he almost came from the reclining chair: "Wan boy, what are you thinking, you are still one in ten thousand, you have never brought soldiers, how come you are one in ten thousand?"

"so!"

Wan Kuan spreads his hands: "Then why does Li Shangshu have to accept me as an apprentice?"

Li Jing pouted, then looked at the steaming cup of tea beside Wan Kuan.

"Boy, hand over your cup of tea."

Wan Kuan looked at Li Jing with disgust on his face: "Li Shangshu, that is the cup of the younger generation. If you want tea, just say hello."

After finishing speaking, Wan Kuan took out another celadon cup from under his case and poured a cup of tea for Li Jing.

Li Jing took the celadon cup, put it under his nose and smelled it, and immediately had an intoxicated expression.

"When this person comes, he likes some subtle flavors. This tea is exactly what I like!"

"Li Shangshu, if you want to drink tea, say it directly, the junior will give you a few pounds!"

After listening to Li Jing, he smiled and said, "Boy, your tea is only used for entertaining guests in Wanfu Building, and you never take it out. Why are you so generous today?"

Wan Kuan laughed and said in a low voice, "Mr. Li, in fact, this tea has a storeroom in my village, and it's not worth much at all!"

"Tricky, there is a city government!"

Li Jing was outspoken.

Wan Kuan raised his eyebrows and gave him tea by himself, only to be stunned by Li Jing: It's too much to belittle.

Unexpectedly, Li Jing went on to say: "Soldiers are tricky.

Wan Kuan, you are the most suitable for military school."

Wan Kuan waved his hand after hearing this: "The military is boring, intrigue and waste of time!"

"you..."

When Li Jing heard this, he trembled with anger: "It's not enough and a plan!"

"Master Li, don't be angry."

"You son of a bitch is so defiled by the military, you deserve to be beaten!"

Wan Kuan was a little unconvinced: "Mr. Li, the younger generation asks you, can this military family beat [-] elite soldiers with [-] elite soldiers?"

"It depends on the right time, place and people!"

Li Jingyan said.

"On the plain, all cavalrymen are in good spirits."

"This..."

Li Jing hesitated: "No way! The military does not use the weak to overcome the strong, but to use the strengths of oneself to attack the weaknesses of others! One thousand to ten thousand, there is no chance of victory!"

"Ha ha!"

Wan Kuan was triumphant: "The military can't, I can!"

"You kid, what's the honor?"

Wan Kuan pointed to his own brain: "Mr. Li, don't you have to follow the junior for the past three days? Then let's see what the junior has a guard of honor!"

After Wan Kuan finished speaking, he took out a small maza from under his case.

The two sides were separated, and Wan Kuan sat on the pony.

Li Jing couldn't help but light up when he saw Wan Kuan's little horse.

"This thing, yes, it's useful for marching and fighting!"

Wan Kuan smiled: "This is the guard of honor for the younger generation."

After finishing speaking, Wan Kuan pointed to the bamboo pipe on the wall and said, "This bamboo pipe that is warm in winter and cool in summer is also the guard of honor for the younger generation, and the steel-making method outside is the guard of honor for the younger generation."

Li Jing's heart moved after hearing this, but his devotion to the military still made him pretend to be disdainful.

"Your bamboo pipe is good, but you can't follow people. It's really freezing and snowing, you... Bamboo pipes are useless!"

Wan Kuan laughed after hearing this, and Li Jing was a little speechless by Wan Kuan's laughter.

After laughing, Wan Kuan pointed to the outside of the house and said, "Why is it so difficult for the younger generation to make a dress for Mr. Li, so that you are not cold at all in the ice and snow!"

After hearing this, Li Jing's eyes flashed with excitement: "Boy, you can't lie to this old man!"

"I, Wan Kuan, only lied to women, not to men."

"Good boy, the old man is waiting for your clothes.

This old man with cold legs, this winter is up to you!"

Chapter 93

Although Li Jing is the oldest, he treats His Majesty's tasks meticulously.

Li Shimin asked him to follow Wan Kuan without leaving an inch, and he really did.

Except... Wan Kuan went home to sleep, as soon as Wan Kuan came out of the house, Li Jing was waiting for him at the door.

Wan Kuan has a big head, and with this old man around, Wan Kuan would not be able to meet Wu Shun'er in private.

And Li Jing is... one followed Wan Kuan, and had to... see Wan Kuan make the water turbine.

Yu Shaojian and Lao Feng were very strong, and they built the frame of the water turbine in one day.

An iron rod is the central axis, which is inserted into the bottom of the river to ensure that the turbine stands still.

The outside of the iron rod is a hollow iron pipe, which is connected to the wheel, the wheel rotates, and drives the iron pipe. Once the iron pipe rotates, the power of the water flow can be converted into the power of the turbine.

It's just that the iron pipe is set on the iron rod, and the water turbine is placed in the Weihe River, and the iron pipe outside must be spinning fast.

But the iron rod inside is fixed and cannot be rotated at all.

This one rotates, the other doesn't rotate, friction, and under it, it must be worn out in a few hours.

In general, bearings must be used in this case, but there are no bearings now.

Although there were no bearings in the Tang Dynasty at this time, from the Northern and Southern Dynasties, someone invented something similar to a bearing, called a potter's wheel.

Probably the same shape and function as the bearing, the potter's wheel is to solve the problem of lubrication.

The drawings of the pottery wheel will be available for both the supervisor and the weapon supervisor. They will take them out and study them carefully. Within half a day, Lao Feng made a pair of pottery wheels out of stainless steel.

Two rings of different sizes, with some small steel balls between the rings.

One of the rings rotates, the other does not rotate, all relying on the rolling of the small steel balls inside to offset the friction.

Things were done, but Yu Shaojian was worried.

Because the water turbine in this new work is too big, the water in the Wei River is too fierce, and the friction between the iron pipe and the iron rod is too violent.

Although this pottery wheel is good, the small steel balls will also wear out under continuous rotation.

At that time, the steel ball becomes smaller due to wear and tear, and the potter's wheel is useless.

This made Yu Shaojian and Lao Feng lose their hair in a hurry. Seeing that they were only one step away from success, they still fell short.

Li Jing was also anxious at this time, if the turbine could not be completed, his horseshoe would be in vain.

And after spending the past two days as a supervisor, Li Jing also understood the greatness of the craftsman.

Many seemingly simple tools can only be produced after a lot of hard work.

At this time, everyone was helpless, only Wan Kuan shook the folding fan with a calm expression on his face.

At this time, the old Feng walked in front of Wan Kuan, and he couldn't raise his head a little: "Supervisor, Xiao: I've let you down!"

Wan Kuan smiled: "No, I am not disappointed, you have already done everything you can."

"But in the end, it still can't be made into a large water turbine. When the time comes, Your Majesty will blame you, Chief Supervisor..."
