Zach brought back 5 white-haired people and 7 black-haired people. Four of the 16 hairy people are children, and the others are women. The men all died on the battlefield with Qiuqiu and the poor. There is no mammoth left, and the dinosaurs don't know where to go, and the only dinosaur is Wang Xijia's Xiaolan.

This should be the only remaining achievement of the black-haired and white-haired people, looking at these only remaining old, weak, sick and disabled, Wang Xijia worked hard to think about the future of these endangered animals. Could it be that the Maoren clan will only end up being reduced to monsters such as Himalayan snowmen and Shennongjia savages?

When he set out from Shanghekou, Wang Xika was bent on going to the beach so that he could draw a map and understand his place in the world. Unexpectedly, as soon as I arrived in Peach Blossom Town, I encountered a war between Mao and craftsmen, and the sea was not found. But Wang Xijia knew that according to the "Historical Records", the Yellow Emperor of the Battle of Zhuolu was killed in "Jizhong", according to the master of Chinese culture Qian Mu's "Historical Records of Place Names", Jizhong is an ancient place name, which should be in the Yuncheng area in the south of Shanxi.

And the place where Heimao is located is somewhat like the Loess Plateau. If you guess correctly, everyone's location should be near Shaanxi, Shanxi, and Henan now, but this is just an inference, and you still need to reach the sea to determine the direction. After all, there are many legends about Chiyou and the Yellow Emperor, and the place where the battle took place may also be in Zhuolu County, Hebei.

The villagers in Shanghekou didn't care so much about their location, and they were very excited to see Wang Xijia and Peng Lianhu come back with a group of hairy people. Half of these dozen hairy people live in Wang Xijia's house, and half live in Peng Lianhu's house. These two people opened a martial arts hall and had a large room.

Wang Xijia went out to travel for a while, and then returned to his "Wang Dawu Pavilion", and there was a feeling of returning home after a long absence. On the contrary, I can't remember the home I lived in before I crossed over, after all, there are no photos to see in this era.

Ah Sen brought a group of brothers who used to play to pick up Wang Xijia's wind, Carpenter Liu brought a few jars of wine, and Lang Naduo slaughtered a few sheep. The moon passed through the white lotus-like clouds, and everyone sat down next to the high pile of grain in the threshing floor and listened to Wang Xijia tell the story of the past.

Zach was originally a more cheerful hairy man, and after drinking a few glasses of wine with everyone, he became happy, and he was not so sad - after all, primitive people often came into contact with death, although there were a little more people who died this time, but they were nothing more than dead people, nothing special. A few little hairy people didn't know what it meant to "exterminate the race", and they ran around with the children in Hekou Village, a harmonious scene of multiracial integration. Wang Xijia wondered why the Maoists and craftsmen never harassed small villages like Shanghekou and Xiahekou, maybe they didn't know about this place.

After coming back, the first thing Wang Xijia did was to go to prospecting for mines, and mobilize all the people who could be mobilized to find mines. In the past, the source of iron ore from the carpenter Liu in the village was basically the one that Wang Xijia discovered last time, and now Wang Xijia has controlled the mine. On the basis of Carpenter Liu and Asen's small workshop, Wang Xijia increased investment and expanded the site a lot, and the scale of the blacksmith shop in Shanghekou after the expansion was completed was 5 times larger than that in Taohua Town.

Wang Xijia, the source of asphalt used by the craftsmen to plot against the Mao, also found, there is a natural oil field near the canyon where the Mao and the craftsmen fought a decisive battle, and the production is so rich that Wang Xika thinks that this is actually the Persian Gulf - in his impression, China is an oil-poor country, and there are no rich large oil fields, which seems to be not the case in ancient times.

Then the salt mine, the coal mine, the copper mine were all found one by one, and Wang Xika even found a gold mine and a jade mine. In modern times, owning these deposits alone would make you the richest man in the world. In this era, although people realized that iron ore and salt ore had a certain significance, they did not care very much, they cared more about the water source, and as for the oil mine, except for the craftsmen used to light the fire, basically no one cared.

As a modern person who has traveled back in time, Wang Xijia naturally knows the significance of these mineral deposits, and he can use these resources to carry out an industrial revolution in Shanghekou.

Although the knowledge is readily available, it took Wang Xijia a week to successfully reproduce the Jenny spinning machine with the cooperation of Carpenter Liu. The women of the village were amazed by the machine, which could weave multiple cotton threads at once, but Wang Xijia knew that this was just the beginning, and what he really wanted to replicate was Watt's steam engine.

Wang Xijia still remembers the steam mechanism construction he learned in textbooks: cylinder, base, piston, crank connecting rod mechanism, slide valve valve mechanism, speed regulating mechanism and flywheel.

But it's one thing to make a machine, you know the principle and the drawings, and it's another thing to actually make it. There is no mold here, every instrument is handmade by Carpenter Liu and Asen, and the size and proportion of each part have no numbers, they can only rely on feeling, and some details Wang Xijia himself has forgotten, so he can only grope for it.

A few people spent 10 hours a day in the studio to reproduce it, and it took almost a month to make the steam engine. This simple steam engine could only do simple straight reciprocating motion, and it often broke down. But Wang Xijia is still very proud: he finally made a steam engine in this post-stone age, and advanced the civilization of this world by at least 3,000 years!

Just like the original steam engine, Wang Xijia and his steam engine were mainly used to dig coal.

Carpenter Liu was puzzled by the necessity of making a steam engine: You dig out coal to burn steam, and the steam is used to drive the steam engine, and then the steam engine is used to dig coal -- if the purpose of digging coal is to make a steam engine, and the purpose of making a steam engine is to dig coal, then what's the point? After spending so much effort for half a day, you can make this thing, then it is better to drink and play ball at home.

Wang Xijia smiled at Carpenter Liu: "Xiao Liu, you don't understand this." Did you know that when we built a steam engine in this era, it means that we are already the king of this world? In this world, you can get anything you want. ”

Carpenter Liu said: "I don't want anything, I just want to go home and drink and play ball." ”

In order to build the steam engine, Wang Xijia called the whole village out to drink and celebrate. Although people don't understand the epoch-making significance of the steam engine, it's always nice to be able to come out and drink.

Wang Xijia was very drunk, drew Mercedes-Benz, Lamborghini, Ferrari car models on the picture, and drew a lot of airplane models, and said to Assen: "Today we have built a steam engine, the next step is to build a fuel engine, and then make an airplane, we can go wherever we want!"

Ah Sen didn't understand what he heard, but he could feel Wang Xika's happy atmosphere, and said vigorously: "Drink and drink." ”

Zach also came over to toast and asked, "Dude, is the steam engine powerful, or the atomic bomb you said last time?"

"Each has its own power", Wang Xika doesn't know how to compare these two things.

"With your steam engine, how can you go to the craftsman for revenge?" Zach did not forget the pain of annihilation.

"The steam engine is just a power plant, and if we want to find a craftsman for revenge, we need to build a weapon device, build a tank or something. Wang Xika said.

"Then let's build tanks. Zach said excitedly.

"Hmm" Wang Xika nodded and agreed. He took a big sip of his wine, and the image of Zach driving a tank with an iron bow and a cast iron heavy sword came to mind, and an adjective came to mind: steampunk.
