Yanagi snapped his fingers and called two professional accountants.

"Help General Cheng calculate how many things you can get for 150,000 guan."

A list with a length of three feet looks at Cheng Biting Jin's scalp numb, and the absolute name is priced.

Liu Mu said to Li Bi at this time: "Take my second brother-in-law to the baggage area." I'm going to go around on my own. ”

The baggage area is a variety of transport vehicles, the most outstanding land transportation in ancient China is the Song Dynasty, and all kinds of baggage vehicles also appeared.

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

Yan Liben, the prime minister of the Tang Dynasty decades later, is also a famous painter of an era. This will become the engineering draughtsman and ghost master of Willowwood.

This research center only studies two things.

Even if you hold the holy decree of the Tang Emperor Li Shimin, you are not allowed to enter here, this is a real forbidden area.

The first thing, bearings.

In ancient China, since the Shang Dynasty had cars, bearings were indispensable, and then 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, and the new research is still in the trial production of the most primitive in the data collection stage, and the roller bearings are still in the trial production stage.

As well as Datang ghost workers have almost succeeded in large and medium-sized copper tile oil-injected bearings.

When Yan Liben saw the arrival of Liu Mu, he showed Liu Mu something like a treasure, only a composite bearing with steel tiles and steel columns the size of a bowl.

"Half a year, up to a year. This thing can be mass-produced, the axles of the carriage will be dozens of times lighter, we have tried on the concrete road, a horse pulled a four-wheeled carriage loaded with a hundred stone of goods, but it can't run. On the gravel road from Sanyuan to Huayuan, a four-wheeled carriage loaded with thirty stone goods can be easily pulled. ”

"There's no money to build roads!" Liu Mu gave Yan Liben the most helpless truth.

Yan Liben sighed heavily: "Alas! It's a pity that the good cars we make, there are no good roads, and the large four-wheeled carriages are not used at all, according to the design, the largest four-wheeled carriage is a double horse, loaded with goods of 100 stones. ”

Liu Muxin said that a hundred stones is five tons.

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

But this kind of carriage needs a good road, a really smooth cement road, and the smooth gravel road can be pulled up to three tons, and normally it will not exceed two tons.

"Old Yan, how is our artifact?"

At the mention of the artifact, Yan Liben's lost expression disappeared in an instant, and he pulled the willow wood and walked to another place.

That's another item that this institute is looking at.

Heavily guarded and not a single rabbit is allowed to approach, this is the pinnacle of Willowwood's industry.

As soon as he entered, Liu Mu was startled, there were all bald heads 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 stronger than a bald head, this was called a short flat head in later generations.

"It's too hot here, and there's fire everywhere. A few months ago, someone burned their hair, and everyone shaved their heads, and it would be terrible to let the fire burn again. And when I work, I am covered in sweat, and it is easy to wash my bald head. ”

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

Liu Mu and Yan Liben didn't bother him, and the two of them came to a workbench, where there was an object three feet long, one foot high, and one foot wide, with a huge wheel, which was spinning rapidly.

Yanagi stared at the wheel and counted silently, about one hundred to one hundred and twenty revolutions per minute.

"How long has this been going around?" Yanagi asked.

"In three months, I changed parts a few times in between, but they were all small parts. The materials and processes of the parts are still being trial-produced, and this is currently responsible for blowing the blacksmith furnace. There's another one over there, which was only built last month, but it's constantly breaking, and now it's cool down with two big fans. ”

Willow nodded, looking closer and seriously.

"Is this a monolith?"

"Yes, single. It's reciprocating over there, and all kinds of small problems are constant, and if we want to use it for a few months without problems like this one, we still need some time to study. The problem of the valve being stuck alone tortured Li Gongzi for a month, and now it is barely solved, but he said that it is not good enough. ”

The steam engine, the key to the industrial time inside the willow wood.

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

"This, I know it's not appropriate." Yan Li said in his heart that it is better not to know such a thing as top secret.

Liu Mu said: "This is the top secret of Datang, do you remember the fire dragon car I told you, you said that you can repair 100,000 miles in one breath, and what it feels like to go to Yanzhou overnight." ”

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

"Then you listen to this secret, I found a super large silver mine on Wa Island, and all the silver can be dug up to bury Chang'an City. So don't worry about the coin, Li Bi will ask the household department and the military department for money. You just let go of the flowers, I just need this steam engine. ”

Yan Liben has not been short of money here over the years, Liu Mu can stop anything, and the money given to him will not be less.

"Old Yan, we don't dare to think about the fire dragon car for five years or ten years, but what about the ship. Load one of these things on the canal, and then pull a string of tugboats upstream, from Yangzhou to Chang'an in three or five days. Five days, eight days from Yangzhou to Bashu, do you feel that this thing is useless, whether there is any real benefit. ”

"Yes!" Yan Liben nodded heavily.

Yan Liben said again: "I thought that in the past year, I will get a few that can be used, this thing can replace the hydraulic loom, although the strength is still a little, it can be used to make a larger one and hang hundreds of yarn machines." ”

"That's right, that's what it means, this thing is a treasure, and it's the pinnacle of my Datang workmanship. Tell those ghost workers that this thing has been caused, and the Tang Emperor will personally canonize them and be awarded the title of Datang Shengong, which is equivalent to the title of a county earl, and the glory of the ancestors. ”

"Yes, yes." Yan Liben nodded violently.

Yan Li was already a famous family, and he believed that if the craftsmen had the title equivalent to the county earl, these people would be more motivated.

On the contrary, Yan Li didn't care about the title, what he wanted was the fire dragon car that was proud of the earth.

Painting beauties or something,It's far better than sitting there and carefully drawing mechanical drawings to make him more fascinated.,What Liu Mu didn't know was that he made a famous and famous top painter into a master mechanic.。

Li Dejian has fallen into a state of obsession and madness, in his eyes, in his mind, in his heart, there is only one thing, that is, the steam engine, and he can't even eat without seeing his steam engine for a day.
