The protagonist still works alone. This tribe is the core key for the subsequent protagonist to drag the regional civilization. After all, it is still a bit difficult to rely on the protagonist to drag the civilization level of 2000 million people alone.

Chapter 94 Steelmaking and then chemical element extraction [First]

Survive Day 26.

The integration of natural selection tribes is almost complete, ranking at the top of the list, and the total output of the No.2 Luohong tribe is close to 2.

While attracting the worship of players from all walks of life, there are also many players who are speculating about who is the big guy behind this tribe.

The prototype of the tribe has been set, and Tang Zheng has no more worries.

After several days of delay, Ming's progress may be overtaken by some players.

However, the small stages of Ming are all small problems, and the first-time rewards given are only average.

If you can get the best, if you can't get it, it will not affect your development.

As long as no one surpasses the Ming stage, it doesn't matter.

Tang Zheng deliberately woke up early today, opened the light curtain, and swept through the eight side tasks of the semi-industrial era one by one.

The steel branch is preferred.

Steel is a superior substitute for iron, and its high-quality material structure is superior to iron in terms of hardness and durability.

And after the steel is produced, it has a wide range of uses, and it can also radiate to the subsequent Ming branch.

Buildings made of steel also have bright grade bonuses.

Reinforced concrete can also be made.

This sturdy building material, mixed with cement, forms the spine of the modern house.

It can be said that it has a lot of effects.

Go back and find time to renovate the small stone house where you currently live.

The bearing capacity of steel bars is very strong, and there is no problem in building a three-story Dabieye.

Ming has only one development goal, which is to enable mankind to live a better life.

Steel, the main element of the alloy product itself, is made from pig iron with a concentration of more than 90%.

So it is also called steel.

In addition to iron, a small amount of carbon, manganese, phosphorus, sulfur and other trace elements need to be added to the finished steel with good texture.

Otherwise, the hardness and stability of steel products will be greatly reduced.It also fails to meet the condition of the high-grade steel given in the side quest.

"Iron, carbon and sulfur are all easy to deal with, but what to do with the remaining manganese and phosphorus." Tang Zheng looked at the description of the properties of steel in the illustrated book, and fell into contemplation.

He tried it just now, and the synthesis table couldn't directly complete the refining of steel.

You need to make it yourself at least once, and you need to draw down the blueprint for production and submit it to the synthesis table for memory absorption, and then you don't need to manually make it yourself. You only need to submit materials to produce it.

All kinds of metal or non-metal elements on the periodic table are not discovered overnight.

They are all precipitated through the long history of human beings for thousands of years.

Although at the Ming level of the original world, there are already very good conditions to refine these elements.

But for most of the players who are still in the Bronze Age at this stage, or even less bright.

It is very difficult to extract various elements of the periodic table.

The so-called beginning of everything is difficult, Tang Zheng intends to start refining phosphorus.

The refining of phosphorus element can not only make steel, but also can make various auxiliary props such as matches, smoke bombs, and incendiary bombs.

Compared with those scientists who discovered phosphorus in the earliest period, Tang Zheng at least has data records, and he only needs to find the right method to get twice the result with half the effort.

Open the illustrated book, enter phosphorus, and soon a bunch of results will appear.

Most of them use high-tech machines to extract phosphorus, which was directly ruled out by Tang Zheng.

If I can have high-tech, I still need to look through the picture book to find the production method?

After screening and screening one by one, Tang Zheng's eyes stayed on an article called the basic extraction method of phosphorus.

I don't know which horn or nook this dedication came from. The illustrated book has a very powerful encyclopedia function of all things. Even the oracle bone records thousands of years ago have long disappeared in the long river of history.

But as long as it has ever been born, it has existed.

Then the Encyclopedia of Everything will definitely be able to find records about it and translate them.

Sometimes Tang Zheng is quite fortunate that he is the first player in the world to obtain SSS-level talent, and he has given the reward of the Book of Everything.

Even if it is taken out alone, it is no less than an SSS-level talent ability.

"Organic life forms contain a certain amount of phosphorus. It is one of the important components to promote teeth and bones. The easiest way to extract it is to extract clams?" Tang Zheng was startled when he saw the last line of words. .

The method of extraction is very magical.

urine distillation

The specific operation method is to heat and evaporate fresh human urine until the water in the urine is dried, and a black residue will remain, which contains a large amount of phosphorus.
