It was dusk now, and the sky was gradually getting dark. Ye Qiong rode on Dudu's back, galloping all the way along the Dinglong Mountains towards the south.
We met a lot of high-level monsters on the road, but Ye Qiong didn't have time to hunt them right now. He had other things to do when he got back. If these monsters didn't run away as soon as possible, they would be killed by Dajun, Dakui and the others sooner or later. Kill them and then bring them back to the tribe to become their food rations.
When the sky was almost completely dark, Ye Qiong arrived at the coal mine base.
He did not stop and continued on his way towards the tribe from the coal mine base along the dirt road that had been pressed out. On the dirt road, his speed also accelerated a lot.
On the east side of the city wall, the sentry in charge of the night guard saw a black shadow running towards this side from a distance. Although he could not see clearly what it was, the soldiers here would not sound the alarm for a monster. .
Moreover, in this case, the soldiers could actually guess that it was probably the young patriarch who was riding the tribe's sub-adult long-tailed bear back.
What's more, if it is a single Warcraft, even if the King Beast rushes directly, in the case of one, with the defensive power of the east wall here, there is no need to be afraid. With the stone wall of the giant crossbow, the defense The force is very powerful.
After getting closer to the charging giant beast, it can be seen that the warriors were stunned just from their outlines and movements. Several large monsters in the tribe would run out to hunt on their own, so for their bodies The movements are very familiar to the sentries standing guard here.
The soldiers continued to be alert and had no intention of opening the city gate.
Because there is no need...
Every time they came back, they would jump in directly. Only when the prey they were dragging was too heavy, they would come to the city gate first and let the soldiers help pull the prey in.
Ordinary low-level monsters are like babies in their mouths, and they jump over with them in their mouths.
"Thump thump thump thump... thump thump thump thump..."
Daidu was very fast. When he arrived in front of the tribe, he didn't have any intention of slowing down. He jumped directly into the air and jumped directly from the seven-meter-high city wall.
After landing, he continued to run towards the central tribe.
It is already late at night, but the soldiers who have reversed their schedules are busy with construction. In the clear night sky, there are many stars, shining on the snowy land, and the visibility is not bad.
In the absence of modern light sources, soldiers can only use starlight to work at night. If it rains, they will have to stop work.
After returning to his residence, Ye Qiong let Daidai move around freely and then began to take a good rest.
The tribe continues to develop at the pace planned by Ye Qiong.
A week later, Ye Qiong, who was studying steam engines in the laboratory, heard the horn sound of the returning caravan, so he called the Mustang King over and ran towards the stone wall on the west side.
The caravan has been traveling for a month and a half. This time, it was lucky. There was no attack by powerful monsters or harassment by madmen. The caravan came back intact. The only bad news...
It was on the way back that the caravan encountered a storm and lost several horses. When the soldiers found them, only bones and dregs were left.
After stopping the horses for a while, the return journey was slightly delayed.
After listening to the situation reported by Yang Jianxin and Tang Li, Ye Qiong arranged for the caravan to return to the central tribe to rest.
Still following the old rules, Ye Qiong waved his hand and pulled the soldiers directly to the door of his laboratory with a cart full of junk.
This time, the raw materials required for the steam engine were basically ready, and Ye Qiong and Tang Ying immediately started working.
After melting all the scraps of copper and iron, Ye Qiong poured them into the mold that had already been made, and began to pour the last few parts of the steam engine.
After the poured parts had completely cooled down the next day, Ye Qiong gathered all the parts together and placed them on the base.
Next…
Just as it was assembled, Ye Qiong was very excited and put the parts together one by one.
Base, bearing, cylinder, flywheel, crank, connecting rod, piston, slide valve...
After the assembly was completed, an epoch-making iron lump appeared in front of Ye Qiong and Tang Ying.
Although Tang Ying only helped Ye Qiong, she didn't really understand what the steam engine meant to Xuexing.
But being able to build this thing with Ye Qiong made Tang Ying feel very accomplished.
especially……
After being instilled with so many modern thoughts by Ye Qiong.
The current steam engine has the simplest principle. As long as it is done well, there will be basically no problems. It is the first generation of machines that convert thermal energy into kinetic energy.
Therefore, Ye Qiong's number for this steam engine is the first generation steam engine 001.
After assembling it, Ye Qiong went to bring a large bucket of water and poured it into the water tank. Then he took out half of the coal that was still burning in the boiler from the laboratory at the back, and put it in the into the boiler above the base.
Soon, the water in the water cylinder was heated to a boiling state, and water vapor began to be generated and rose upward into the cylinder. As the pressure in the cylinder increased, it began to push against the top The piston began to rise slowly.
After reaching the critical point, the steam turns into exhaust gas and is released to the outside world. The pressure inside the cylinder decreases rapidly, and the piston begins to fall under the action of gravity...
The cycle repeats itself, and as long as the coal at the bottom continues to provide heat and the water supply continues, the steam engine can continue to operate.
"Dong...dongdong...dongdongdong..."
The steam engine began to shake. At the same time, the crank was driven by the connecting rod on the piston and began to rotate. After being transmitted by the bearing, the flywheel began to rotate.
Some of the surrounding tribesmen were attracted by the strange sounds here.
I saw a big iron thing at the door of Ye Qiong's laboratory, about twenty meters on the ground, making a weird buzzing sound, and a round wheel that was spinning rapidly. …
They couldn't understand what this wheel would mean to the tribe and even Snow Star after it started spinning.
Everyone is curious in their hearts, what is the use of such a useless iron lump that the young patriarch has researched.
Seems pretty excited...
The young patriarch picked up the beautiful woman from the caravan next to him and spun her around.
Ye Qiong was very excited at the moment.
The rapidly rotating wheel is the source of power and can transform countless derivative energies and technologies.
After placing Tang Ying on the ground, Ye Qiong pulled out the coal from the small boiler on the base.
As the temperature dropped, the piston slowly stopped, and the flywheel at the edge also stopped.
