Tang Dynasty good brother-in-law

Chapter 642
Liu Mu snapped his fingers and called two professional accountants.

"Help General Cheng do the math, 15 guan, how much can you get."

Cheng Yaojin's scalp was numb looking at a list that was three feet long.

Only then did Liu Mu say to Li Bi: "Take my second brother-in-law to the luggage area. I'll go around by myself."

The luggage area is all kinds of transport vehicles. The most outstanding land transportation in ancient China was the Song Dynasty, and various luggage vehicles also appeared.

The place Liu Mu went to was a Datang version research center that spent thousands or even tens of thousands of guan a year.

Yan Liben, the prime minister of the Tang Dynasty decades later, is also a famous painter of an era.This will become Willow's engineering draftsman and chief ghost worker.

This research center only studies two things.

Even if you hold the imperial decree of Emperor Li Shimin of the Tang Dynasty, you are not allowed to enter here. This is a real restricted area.

The first thing, the bearings.

In ancient China, since the Shang Dynasty had cars, bearings were indispensable, followed by ceramic bearings in the Han Dynasty, cast iron bearings in the late Han Dynasty, and copper bearings in the early Tang Dynasty.

Then there are graphite copper bearings here. New research is still in the trial production stage of data collection, the most primitive roller bearings that are still in the trial production stage.

And the large and medium-sized copper tile oil-filled bearings that Datang Guigong has almost succeeded in.

When Yan Liben saw Liu Mu's arrival, he showed Liu Mu something like offering a treasure. There was only a bowl-sized composite bearing with steel tiles inlaid with steel columns.

"Half a year, a year at the most. This thing can be produced in energy, and the axle of the carriage will become dozens of times lighter. We have tried to pull a four-wheeled carriage loaded with a hundred stones of goods on a concrete road, but it can't run. Get up. On the gravel road from Sanyuan to Huayuan, you can easily pull a four-wheeled carriage loaded with thirty shi."

"There is no money to build roads!" Liu Mu gave Yan Liben the most helpless fact.

Yan Liben sighed heavily: "Alas! It's a pity that the good cars we made, without good roads, the large four-wheeled carriages are useless at all. According to the design, the largest four-wheeled carriages are two horses, and they can carry hundreds of stones of goods. "

Liu Muxin said, one hundred stones is five tons.

Such a large carriage is more powerful than the trucks of World War II in the modern age of later generations.

But this kind of carriage needs a good road, a real flat concrete road, and a flat gravel road can pull up to three tons, and normally it will not exceed two tons.

"Old Yan, how about our artifact?"

When mentioning the artifact, Yan Liben's lost expression disappeared in an instant, and he pulled Liu Mu to another place.

That's another object that this institute studies.

The surrounding area is heavily guarded, and even a rabbit is not allowed to approach. This is the pinnacle of Willow's industry.

As soon as he entered, Liu Mu was startled, all of them were bald here, and the noble son Li Dejian was also bald.

Yan Liben took off his hat and showed it to Liu Mu. He was not much better than a bald head, which will be called a short crew cut in later generations.

"It's too hot here, and there are fires everywhere. After someone burned their hair a few months ago, everyone shaved their heads, and it's terrible to let the fire burn again. And when I work, I'm sweating all over my body, and it's easy to wash with a bald head. "

Li Dejian knew that Liu Mu was coming, but he didn't look up at all, and was engrossed in calculating the data on the map.

Liu Mu and Yan Liben didn't bother him, they came to a workbench, there was a three-foot-long, one-foot-high, and one-foot-wide object with a huge wheel, and the wheel was spinning rapidly .

Liu Mu stared at the wheel and counted silently, it was about 120 to [-] revolutions per minute.

"How long has this been spinning?" Willow asked.

"Three months, several parts have been replaced in the middle, but they are all small parts. The materials and craftsmanship of the parts are still being trial-produced. This is currently responsible for blowing the blacksmith's furnace. There is another one over there, which was completed last month. , but it keeps breaking down, and now bringing two big fans can make the place cooler."

Liu Mu nodded, and watched carefully.

"Is this single?"

"Well, the single type. There is a reciprocating type over there, and there are various small problems. If we want to use it for a few months without any problems like this one, we still need some time to study. The problem of the valve being stuck is just a torment. It took Mr. Li a month, and now it is barely resolved, but he said it is not good enough."

The steam engine, the key to industrial time in the heart of Willow.

Liu Mu put Yan Liben on the shoulder: "Old Yan, don't care about spending money. I will tell you a top secret in the Taiji Palace in private, and you can only tell Li Dejian about this."

"This, I know it's inappropriate." Yan Liben said in his heart, it's better not to know things like top secret.

But Liu Mu said: "This is the top secret of the Tang Dynasty. You remember the fire dragon car I told you. You said how it feels to build a hundred thousand miles in one go and reach Yanzhou overnight."

"If you can see it in this life, you will die without regret."

"Then you just listen to this secret. I found a super large silver mine on Wa Island. If I dug out all the silver, it could bury Chang'an City. So don't worry about the coins. Li Bi will take it seriously Ask the Ministry of Households and the Ministry of War for money. You just let go of the flowers, and I only want this steam engine."

Yan Liben has never been short of money here these years, Liu Mu can stop at anything, and the money given to him will not be less.

"Old Yan, we don't dare to think about the dragon car for five or ten years, but what about the boat. Put one of these things on the canal, and then pull a string of tugboats up the river, and go from Yangzhou to Chang'an in three or five days. Five or eight days From Yangzhou to Bashu every day, do you think this thing is useful, is there any real benefit."

"Yes!" Yan Liben nodded heavily.

Yan Liben added: "I was thinking about getting a few usable ones in the past year. This thing can replace the hydraulic loom. Although it still has a little strength, it would be useful to make it bigger and hang hundreds of yarn looms."

"By the way, that's what it means. This thing is a treasure, and it is the most peak divine work of my Tang Dynasty. Tell those ghost workers that this thing is made, and the Emperor of Tang Dynasty will personally confer titles on them, and they will be granted the title of Great Tang Divine Workmanship." Noble, equivalent to the title of a county earl, honor your ancestors."

"Yes, yes." Yan Liben nodded sharply.

Yan Liben was originally from a famous family, and he believed that if the craftsmen had titles equivalent to county counts, these people would be more motivated.

On the contrary, Yan Li didn't care about the title anymore, what he wanted was the fire dragon chariot that looked down upon the earth.

Drawing beauties is far less fascinating to him than sitting there and meticulously drawing mechanical drawings. What Liu Mu doesn't know is that he forcibly turned a top-notch painter who is famous for future generations into a master of mechanics.

Li Dejian has fallen into a state of obsession and madness. In his eyes, in his mind, and in his heart, there is only one thing, and that is the steam engine. If he doesn't see him for a day, he can't even eat with the steam engine.
