Chapter 196
――――
The protagonist still does it alone. This tribe is the key to the civilization of the follow-up protagonist’s drag area. After all, I want to rely on the protagonist to drag 20 million alone. The civilization level of the population is still a bit difficult.
Chapter 94 Steelmaking and then extraction of chemical elements [First update]
The 26th day of survival.
The integration of the natural selection tribe is almost completed, ranking first, and the second-place Luohong tribe has opened up close to 2w of total output.
While attracting the worship of players from all walks of life, many players also have everyone talking at once guessing who is behind this tribe.
The prototype of the tribe has been set, and Tang Zheng doesn't worry about it anymore.
After a delay of several days, Ming's progress may be overtaken by some players.
However, the minor stages of Ming are all minor problems, and the awards for first creation are only average.
You can get the best, and if you don't get it, it will not affect your development.
As long as no one surpasses the Ming Dynasty, it is nothing.
Tang Zheng deliberately woke up early today and turned on the light curtain to sweep the eight semi-industrial era side missions one after another.
The branch line of steel is preferred.
Steel is a superior alternative to iron, and its high-quality material structure is better than iron in terms of hardness and durability.
After the steel is produced, it has a wide range of uses, and it can also be radiated to the subsequent bright branch lines.
Buildings made of steel also have a level bonus.
Reinforced concrete can also be made.
After mixing this strong building material with cement, it becomes the backbone of modern houses.
It can be said to have a lot of effects.
When I look back, I can find time to renovate the small stone house I currently live in.
The load-bearing capacity of the steel bar is very strong, so it is no problem to build a three-story big field.
Ming has only one development goal to enable human beings to live a better life.
Steel, the main element of the alloy product itself, is made from over 90 pig iron.
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 conditions of High Level steel given in the side mission.
"Iron, carbon, and sulfur are all easy to handle, but how to handle 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, but the synthesis platform could not directly refine the steel.
You need to make it yourself at least once, and submit the blue picture to the synthesis table for memory absorption. Then you don’t need to make it manually, you only need to submit the materials to produce it.
The discovery of various metal or non-metal elements on the periodic table did not happen overnight.
They are all deposited through the thousands of years of human history.
Although with the original world level, 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 clear.
It is very difficult to extract various elements of the periodic table.
The so-called everything is difficult at the beginning, Tang Zheng plans to start to refine the element phosphorus by hand.
The extraction of phosphorus can not only make steel, but also 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 has at least data records. Just find the right method to double the results for half the effort.
Open the picture book, enter the phosphorus, and soon a bunch of results come out.
Most use high-tech machines to extract phosphorus, which was directly ruled out by Tang Zheng.
If you can have high technology, you still need to look through the illustrations to find the production method?
One after another After screening and screening, Tang Zheng's gaze stayed on a presentation on the basic extraction method called phosphorus.
I don’t know from which corner of the tribute this offering was retrieved. The illustrated book has a very powerful encyclopedia function. Even the oracle bone records thousands of years ago have long disappeared in the long river of history. middle.
But as long as it was born and existed.
Then the Encyclopedia of All Things must be able to find a record about it and translate it.
Sometimes Tang Zheng is very fortunate that he is the world's first player to obtain the SSS-Rank innate talent, and he has given the prize of the All Things Illustrated Book.
Even if it is taken out separately, it is no less than an SSS-Rank Innate Ability.
"How much of the organic lifeform contains a part of phosphorus, which is one of the important components to promote teeth and bones. The easiest way to extract is clams?" Tang Zheng sees the last line of words At that time, his eyes were startled.
The method of extraction is very magical.
Urine distillation method
The specific method of operation is to heat and evaporate fresh human urine until the water in the urine is dried, leaving a part of black Residue, there is a large amount of phosphorus among them.
Put these black residues in a damp place to let it decompose, and then add a certain amount of fine sand to mix for secondary distillation.
This time choose to collect the evaporated water.
After the water solidifies, a white yellow solid substance, phosphorus, is formed.
"emmm"
Although it sounds very spoof, Tang Zheng checked the Pictorial Encyclopedia.
In the long history of mankind, the person who discovered the element phosphorus for the first time really tried this method
but the reason for extracting urine is very nonsense.
It is like the first human to extract gunpowder, just want to see if this substance can make an immortality medicine pill.
The idea of people who refine medicine is the first to commit the crime of greed!
He thinks there is a small amount of gold in the urine, otherwise, why is it pale-yellow?
