Bai Mei has been waiting outside the Liangyi Hall for a long time.

Seeing that Empress Changsun followed Li Er out of the main hall, she came up with a wrinkled smile on her face, and at this time, her white eyebrows couldn't be seen at all, and she was really harmless like a little eunuch.

Outside the Liangyi Hall is a huge white stone clearing, the steam car made of wood is lying quietly prone on the vast white stone square, Foreman Cai and Zheng Wen and several craftsmen who are responsible for driving are kneeling on the ground, trembling, this life can be summoned by His Majesty the Emperor, which makes these rural grass people have been excited.

Li Er looked at the group of craftsmen kneeling below with satisfaction, this is the attitude that the face saint should have, conscientious and cautious, like Xu Yang when he first faced the saint, what is going on?

Li Er coughed, looked around the steam car twice, and asked with a full temperament: "This thing is a steam engine?" ”

Foreman Cai raised his head tremblingly and said, "Returning to Your Majesty, this thing is a steam car, and the all-iron zuò on it is a steam engine." ”

Li Er was very interested in touching the thing called the steam engine, this strange thing is mainly a large iron cylinder, with several long iron bars connected on it, and he knows a little bit about the mechanism, but this thing in front of him has never been seen before.

"Show me how to use it." Li Er turned his head and ordered Xu Yang.

"No." Xu Yang nodded, and then said to Foreman Cai: "Foreman Cai, you can start." ”

Although the little old man Cai was more scared when he saw His Majesty, once it was related to his own field, he immediately became confident.

Tilting his neck, Foreman Cai shouted to the craftsmen standing next to the steam engine: "Add charcoal, burn the fire!" ”

I saw one of them jump on the steam car, step on the blower with his feet, and the other three kept adding charcoal to the steam stove, the steam engine emitted black smoke and moved slowly, Bai Mei stood in front of Li Er with a vigilant face to guard against any danger, the iron pillars on the steam engine began to rotate slowly under the impetus of the steam, the gears were staggered, and the two wheels of the steam locomotive were gradually driven.

Li Er looked at the gradually starting steam car with a solemn face, Empress Changsun was also very curious about such a big guy who could move on his own without something to pull, as for Li Chengqian and Li Tai, the two princes were already stunned in shock.

The start of the steam car was very slow, but once it ran fast, the craftsman on the steam car no longer continued to step on the blower, but sat in front of the whole steam car, the steam locomotive ran fast in front, at this time the craftsman held a round roulette wheel with his hand, and when everyone was curious about what this roulette was, I saw the craftsman turn the wheel wheel, and the whole steam engine quickly turned a corner, and then drove towards Li Er.

Li Er's eyes were blazing, and he didn't know what he was thinking, as for the others, they were stunned.

The craftsman was very respectful, and he stepped on the brakes when he was still far away from Li Er, and the speed of the car quickly decreased, and finally stopped in front of Li Er.

Li Er's expression couldn't see joy and sorrow, he looked stern, and the frightened craftsmen all knelt down and bowed their heads and didn't dare to look directly.

Li Er thought for a while before turning his head to Xu Yang and asking, "Sure enough, it's a magical thing, it doesn't consume horses, and it can walk on its own, but I just heard about adding charcoal to make a fire, I don't know how much charcoal this steam engine needs to consume when it starts?" ”

Xu Yang nodded, the emperor's thoughts were really more than others. He raised his head and said: "Back to Your Majesty, there is no coal now, and it costs several catties of charcoal to start the steam car every time, and charcoal is also burned and supplied every kilometer." ”

"A few pounds of charcoal is not too much, but what are you talking about coal?" Li Er asked curiously.

"Returning to His Majesty, coal is a fuel buried deep in the ground, also known as black stone, black gold, and graphite. It can be made into an ink sculpture" Xu Yang felt that he needed to explain it clearly to facilitate his money-making plan.

"Oh?" Li Er thought for a moment and said, "Isn't this the stone nirvana mentioned in the "Classic of Mountains and Seas"? ”

"That's it." Xu Yang couldn't help nodding.

"This thing is buried deep underground, and it is very difficult to obtain, what do you say this thing is for?" Li Er stared at Xu Yangdao.

Xu Yang was very excited in his heart, and said: "As a disciple of the Ghost Valley, the minister is looking for dragon points, and the ability to identify mineral veins can be said to be few people in this world, and the minister has found a few coal mine veins near Chang'an, my master said that the steam engine is a bone, coal is a muscle, and with the blood of oil, the world of Datang will become a giant standing on top of the sky." ”

Li Er was a little surprised and said, "These three things that I haven't heard of are so important?" I think you should do it as the main thing you need to do when you're looking for crops overseas. ”

Xu Yang said with a smile: "Your Majesty doesn't know, only after the invention of the steam ship, General Niu can cross thousands of rivers and mountains to bring overseas high-yield crops back to my Datang, otherwise he will travel across the sea with manpower, and he will not be able to come back for two or three years." ”

Li Er's eyes lit up, and he said, "Are you saying that this steam engine can not only make a car running on the road, but also a ship running on the sea?" ”

Xu Yang was very excited: "Not only these, with the steam engine, Datang's textile industry, farming industry, mining industry, paper industry, etc., all can enter a new era!" ”

Li Er's face turned slightly pale in the sunlight, he clasped his hands and asked, "Sue Sù, where are those coal mines?" ”

Xu Yang hummed a small tune out of the palace, the carriage was full of people, Foreman Cai was named a royal craftsman by the emperor, and Xu Yang was responsible for manufacturing the steam industry, there was no silver reward, but ten horses of silk per person, which was more grand than the silver reward.

Xu Yang is in a good mood, the ownership of the coal mine and His Majesty have been negotiated, Xu Yang is responsible for a series of mining and mining applications, and the royal four or six shares, although the royal family can take away sixty percent of the big share without doing anything, Xu Yang didn't say anything, after all, the world is Li Er's, how much Li Er can give, it all depends on whether he is in a good mood or not, and it is already very good to get four achievements.

Xu Yang wrote a contract on the spot, and he wanted to sign it with Li Er in triplicate, Li Er felt very weird, but after hearing the spirit of the contract that Xu Yang said, Li Er was very happy to sign his name.

It is said that Xu Yanggan is already handy in this business, and when he established the company in Youzhou, he signed a contract with those officials in Youzhou.

The spirit of contract is very well understood in the Tang Dynasty, that is, the issue of integrity, which has produced striking similarities between the social economy of the East and the West, the social economy has its own reason, the rights of the outside world do not interfere with it, and trade needs to be honest since ancient times.

This point is generally recognized in both the East and the West, but the West calls it 'contract spirit', and the East calls it 'trustworthiness and sincerity'.

Li Er was very curious about Xu Yang's contract, and felt that the merchants of Datang should also promote this model, and had already ordered the Ministry of Rites to draft a decree.

However, this qiē is not important to Xu Yang, what he wants to do most now is to quickly find the ore vein west of Chang'an, and then dig out his own money and become a world-famous coal boss.
