The people of the entire tribe were busy all day, and after dinner, Chen Bing let the tribe rest early.

"Big brother, what's the use of this strange thing?"

In the wooden house, Princess Shelley was massaging Chen Bing's shoulders while curiously looking at the core of the steam engine placed on the ground.

"It works a lot, a proper black technology."

Chen Bing briefly told Shelley what the core of the steam engine could do.

On the way back, he had already made a general acquaintance.

The core of the steam engine is the drive of a multi-functional processing plant, and a single one cannot play a role, but with a variety of supporting tools, it can play a many roles.

At present, Chen Bing has only seen part of the configuration drawings, and he can make the supporting tools, and logging, forging, stamping, cutting, smelting, etc. are not a problem.

However, the core of a steam engine has six sides, the top position is the entrance of coal fuel, the back side is the water source inlet, and the lower side should be placed on the ground, which can support the operation of three sets of supporting tools at the same time.

Many of these tools are not easy to make, and they require a variety of metal components and wooden parts.

But Chen Bing has a lot of books on various aspects in his hands, and it is not a problem to spend a little more time and build some metal components by hand.

As for the precision wooden parts, Chen Bing just got a chainsaw, and it was not difficult to build it.

Combined with the existing conditions, Chen Bing has a plan for what supporting tools to do first.

At present, the tribe needs the most wood, and the second is metal.

Parts for logging, cutting, and smelting will be the focus of priority manufacturing.

……

The next day, Chen Bing assigned new jobs to most of the tribe's inhabitants, and a considerable number of them were assigned to dig iron and coal mines.

Iron ore and coal mines, not too far away from the tribe, but the reserves are too small to be used to make too many tools.

However, the accessories used to make the core of the steam engine are sufficient.

Knowing that Chen Bing was going to teach them how to make iron tools, these residents did it energetically, even if they were not coolies.

At the same time, Chen Bing also taught Mickey and the others how to use chainsaws, and took out the carpenter books they obtained, taught them some basics, and let them learn the knowledge in the books by themselves.

It was a novel day for many of the tribe's inhabitants, and the day went by quickly.

At noon and in the evening, after dinner, Chen Bing and Shelley would teach the residents to read and write, laying the foundation for them to learn about books.

At the same time, Chen Bing officially announced that he would build a school in the tribe, and residents who can read and read well and have a deep understanding of a certain book knowledge will be able to become teachers, and they will not need to do anything else in the future, as long as they teach other residents to read and learn books and knowledge in the tribe every day, and live a safe and comfortable life.

The inhabitants were shocked, especially a few sacrifices, and they were even more moved.

The priests were originally the smartest and most knowledgeable people in the tribe, and with a little hard work, it was not difficult for them to become teachers.

The other residents were also excited, and they all wondered if they could do it, and they had to work hard.

Even if you don't plan to become a teacher, you are looking forward to learning new knowledge.

One day passed, and the next day, the game time came to the 8th day.

Early in the morning, many villagers gathered around the beach.

Chen Bing began to assemble accessories for the core of the steam engine.

This is a small part of ore smelting.

Taking advantage of the high temperature generated by the combustion of coal, Chen Bing used the large iron furnace yesterday to pour a large piece of iron into it, which was used to forge and purify the ore.

Seeing a large white mist coming out of the core of the steam engine, and then a large piece of iron that a person could not move at all was easily lifted up and smashed on the ore below, making a loud noise, smashing the solid ore into pieces, and even the iron ore part was also smashed, the residents who watched couldn't help but feel extremely shocked.

They all realized that their tribe was going to be truly different from today onwards.

With this thing, the tribe can obtain a lot of metal and make a lot of metal tools and weapons.

System prompts kept floating in front of Chen Bing's eyes, and the loyalty of the new residents was constantly improving.

Today is also the day of the first harvest on the tribal farmland, and the 300 portions of wheat that Amanda and her family are responsible for planting have been harvested today.

Thanks to the more than 10 farmers in the tribe, the wheat harvest was quickly completed.

Some of them were stolen by birds and beasts on the way, but the weather was fine, and more than 1,300 servings of wheat were finally harvested.

[System: The territory meets the upgrade conditions, the level is increased, and the current level is "Level 1 Iron Civilization"! 】

[System: You get 6 free attribute rewards, an additional 10 free attribute points, strength +3, stamina +3, agility +2, spirit +3]

[System: Complete the additional upgrade conditions and get a "Random Ruins Map"!] 】

"Random Ruins Map: After use, it will show the closest ruins to the player and have not been fully explored, after obtaining the location of the ruins, it is best to explore them as soon as possible, if someone nearby uses the random ruins map, it is possible to get the same ruin information"

……

After the farmland was harvested, the tribe was promoted to a level 1 iron civilization.

And this time, the attributes rewarded are also unprecedented, and a random relic map is also rewarded.

What about the next level of escalation?

Chen Bing looked at the upgrade conditions of the Level 2 Iron Civilization with great spirits.

"200 people living in the territory"

"There are 50 buildings in the territory that the inhabitants will not dislike."

"The inhabitants have successfully crafted 1 iron tool or weapon."

"A resident with 1 level 5 or higher and 10 level 4 or higher crafts"

"Establish a new territorial functional organization, which needs to be recognized by 50% of the residents"

The upgrade conditions for the level 2 iron civilization appeared, and Chen Bing glanced at it and found that the upgrade conditions seemed to be simpler.

Several upgrade conditions, he will be able to achieve them all in the next two days.

It's going against the rhythm of the sky!

……

Selena decided to come with Skymark in person, because she didn't worry about other residents, and she also wanted to come and learn in person.

But when she came to Chen Bing's tribe, it was only a few days before she felt that her worldview was about to be subverted.

In just four days, this tribe, which was a little smaller than her father's tribe, completely changed.

The day after she arrived, the strange machine was in operation, forging stamping ore, and that afternoon, the inhabitants of the tribe began to use it to create a new weapon.

On the third day, the strange machine, ready to start cutting, a large amount of wood was easily and neatly cut into wood, and neatly planks.

Wooden houses have sprung up like mushrooms after a rain, and one of the largest of them is the wooden house called the "school", where dozens of people can sit at the same time to study books and knowledge, and many residents, even her, began to run there.

On the fourth day, many new parts were added to the machine, and the lord, who was older than her, was ready to start building ships and building docks.

At the same time, the tribe welcomed a large number of new residents, and the number of residents has risen further to more than 250 people.
