The world is always moving slowly according to a certain law, and at a certain time there will be something that will change the era.

Xu Yang thinks that the steam engine is such a thing.

This is a great invention, and its transformation and construction, promotion and application are the signs of an era.

It completely liberates manpower from natural farming and labor, and exerts the transformation and utilization of thermodynamics and thermokinetic energy to the extreme.

L.S. Stavrianos, author of The General History of the World, once said, "The historical significance of the steam engine cannot be exaggerated." It is enough to see that this invention has left a prominent mark on human history and civilization.

Xu Yang handed over the drawings of the steam engine to the craftsman team in Youzhou very early, but this iron steam engine is not said to be manufactured, pressure control, steam drainage, axle inlay, especially the leakage of pistons and cylinders These all need to be carefully studied before starting.

In the end, under the leadership of the genius boy Zheng Wen, the blacksmith team lasted two months, and finally overcame all kinds of difficulties and made the steam engine.

In the more than two months that Xu Yang came to Chang'an, these people really built a steam wooden car that could run on the ground according to Xu Yang's theoretical drawings of the steam car.

A group of convoys traveled for half an hour to arrive at the fiefdom of Zhongnan Mountain, the mountains are towering and green, the clouds are stacked, the beautiful scenery here makes people overjoyed, it is difficult to go up the mountain, but after the number of people, everyone communicates at will on the road, but does not feel bumpy.

After bypassing the two mountains, we arrived at the Zhongnan Mountain fiefdom of Xuyang.

The plain hidden in the two peaks is still the same, the forest is full of bamboo, the farmhouse people, the smoke is curling, the chickens are crowing and the dogs are barking, the life of the farmers does not seem to have changed, along the dirt road, to the door of the village, the slightly dilapidated archway still hangs the black plaque that has fallen off the paint, and the words "Chang'an County Village" on it are announcing that its current owner is Xu Yang.

The noise of the convoy soon attracted the villagers of the farmhouse, all of whom stretched out their heads to look at the convoy, and it was a big scene for them to have so many carriages.

Xu Yang walked in the front, followed by Liu Qi and Zhang Er, two loyal servants, behind him was a group of black-clothed men, then craftsmen in craftsman clothes, and at the back there were more than a dozen old men in white robes.

Xu Yang entered the village, and an old man greeted him, it was the old man Cai Yi of Zhongnan Villa.

"Hou Ye Wanfu, welcome Hou Ye." The old man saluted, and the farmers behind him also fell to their knees.

"Get up." Xu Yang didn't like the etiquette of the Tang Dynasty very much, and he had to kneel to people with high positions at every turn, which seemed very spineless.

"Master Xie." And all the people got up.

Cai Yi glanced at the people behind Xu Yang and asked tentatively, "Master Hou, where did these people come from?" So what's going on? ”

Xu Yang said with a smile: "These people will become our Zhuangzi people in the future, don't worry." ”

But when he said that, Cai Yi's face was obviously a little bad, listening to Hou Ye's words, it seemed that he was planning to place these people here permanently, there were so many fields, and the annual autumn harvest was a little reluctant to feed the entire Zhongnanshan Village, not to mention adding a few hundred more people.

Cai Yi's face was already gray, and he felt that he had to persuade this Hou Ye, otherwise if he continued like this, the whole village would starve to death with him.

"Lord Hou, you are high up and don't know the hunger of our small people, there are so many fields in this field, a few days ago I heard that the lord said that the northern slope can also be farmed, and now the men, women and children of the whole village have gone to reclaim the mountain, and after collecting rent from these fields, they are barely making ends meet, and adding a few hundred more people will die of old age, it is estimated that this winter will not be able to survive." Cai Yi snorted and cried, and what he said seemed to be very hard.

Xu Yang couldn't laugh or cry, this guy thought that these people he brought were in vain.

He helped Old Man Cai up, and said softly: "Old Cai don't worry, these people have their own means of livelihood and don't eat the food of the farmers in the village." ”

When Lao Cai heard this, he immediately stopped crying, feeling that these people are all invited craftsmen?

Xu Yang said with a smile: "These are my subordinates, and they have been developing some things recently, and I will give them regular silver every month, which is enough for them to buy food in Chang'an City." ”

When Lao Cai heard that it was Hou Ye's self-raised staff, he had nothing to do, so he hurriedly wiped his face and said guilt. Xu Yang didn't care, and told him that he wanted to build the mansion of the Hou Ye, and these people lived in the Zhuang family for the time being, and after a while the mansion was built, these people would live on Xu Yang's mansion, so they got up and went to choose the site.

The legal grant of the founding county marquis is 14 hectares, so the size of the Xuyang mansion is also 14 hectares, and the Xu Yang of later generations is a complete house slave, for no other reason, 'If you want not to buy a house, you must first get your mother-in-law.' Xu Yang didn't have the ability to handle his mother-in-law, so he had to work for the evil capitalist and become a complete house slave.

The little salary that he has earned every month has all gone into the pockets of real estate developers, but this is also Xu Yang's willingness, every time he steps on his 120 square meters of small world, Xu Yang has a sense of stability, although this 120 square meters he only has the right to use for 70 years, but how to say that he has worked hard to get it.

But now, fourteen hectares of land, Xu Yang can choose anywhere, what is the concept of fourteen hectares, one hectare in the Tang Dynasty is equal to fifty acres of land in later generations, and fourteen hectares is a full seven hundred acres of land, which is now in the name of Xu Yang.

People's wallets are proportional to courage, this sentence has been true since ancient times, at this time Xu Yang, who is wealthy, plans to build a mountain next to Zhongnan Villa into his own mansion, just right, behind this mountain, is the Taoist Zongsheng Palace, Xu Yang feels that with his friendship with Yuan Tiangang, the future visit must be indispensable, and it is not good to be able to raise the chemistry department to an unimaginable height.

After making up his mind about the decision to use the opposite hill as his mansion, Xu Yang began to settle everyone.

All the goods were unloaded from the carriage, especially Xu Yang's computer printer and player, Xu Yang kissed him twice, these things are the capital of his survival in Datang.

The next thing that was unloaded from the carriage was the steam locomotive, because a wooden car was too big, the craftsmen of the Liu family dismantled the entire steam wooden car into five parts and loaded it into the carriage, and because of this thing, they were interrogated along the way.

More than a dozen craftsmen skillfully took the parts of the steam car off the carriage, and then began to piece together the steam car on the ground, the parts are all made by the top blacksmiths in Youzhou, and every screw and nut is made together, completely in accordance with the standard of the 'scale ruler'.

After more than half an hour, the steam wooden car was assembled, looking at the strange iron cylinder and the towering boom that looked even more weird, Xu Yang really couldn't imagine how this strange thing was similar to the cars of later generations.

Foreman Cai looked at this car with a fluttering beard, like looking at a beautiful dancing girl, he slowly walked in front of Xu Yang, and said proudly: "Childe, according to the drawings you gave, we craftsmen spent two months in Youzhou, and finally finished the steam car you said." With that, he bowed down and stood beside Xu Yang waiting for the order.

"Okay." Xu Yang nodded, "Let it run and take a look now." ”

Foreman Cai shouted excitedly: "Add charcoal, burn the fire!" ”

Billowing smoke poured out of the chimney above the steam wooden cart.
