Chapter 94

Survival day 26.

The integration of natural selection tribes is almost complete, ranking at the top of the list, and the total output is close to 2W + compared with the second Luohong tribe.

While attracting various players to worship, many players have speculated about who is behind the tribe.

The prototype of the tribe has been set, and Tang Zheng doesn't worry any more.

After several days of delay, I'm afraid the civilization progress has been overtaken by some players.

However, the small stages of civilization are small problems, and the initial rewards given can only be regarded as general.

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

As long as no one surpasses in the stage of great civilization, it's nothing.

Tang Zheng got up early in the morning and opened the light curtain to sweep the eight branch tasks in the semi industrial era one by one.

The 'Steel' branch line is preferred.

As the superior substitute of iron, steel's high-quality material structure, whether hardness or durability, is better than iron.

Moreover, after the steel is produced, it can be widely used and can also radiate to the subsequent civilization branch line.

Buildings made of steel also have a civilization level bonus.

Reinforced concrete can also be made.

This solid building material, mixed with cement, has become the backbone of modern houses.

It can be said that it plays a lot of roles.

Later, you can find time to renovate the small stone house you currently live in.

The bearing capacity of the reinforcement is very strong. There is no problem in building a three-story Dabie field.

There is only one goal for the development of civilization, which can enable mankind to live a better life.

Steel, the main element of the alloy product itself, is made of more than 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. Nor can it meet the condition of "high-grade steel" given in the regional task.

"Iron, carbon and sulfur are easy to get, but how to operate the remaining manganese and phosphorus." Tang Zheng looked at the description of the nature of 'Steel' in the picture book and fell into meditation.

He has just tried. The synthesis platform cannot directly refine steel.

You need to make it yourself at least once, and submit the blue picture to the synthesis platform for memory and absorption. Then you can produce it without manual manufacturing. You only need to submit materials.

All kinds of metallic or non-metallic elements on the periodic table are not found overnight.

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

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

But at this stage, most players are still in the bronze age, or even less civilized players.

It will be very difficult to extract all kinds of elements in the periodic table.

It is said that everything is difficult at the beginning. Tang Zheng plans to start refining phosphorus.

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

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

Open the atlas, input "phosphorus", and soon a pile of results will come out.

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

If you can have high technology, you still need to look through the atlas to find the production method?

After screening one by one, Tang Zheng focused on a document entitled "basic extraction methods of phosphorus".

I don't know where this document came from. The atlas has a very powerful encyclopedia function. Even the Oracle records thousands of years ago have long disappeared in the long river of history.

But as long as it was born and existed.

Then the Encyclopedia of all things will be able to find records about it and translate it.

Sometimes Tang Zheng is very glad that he is the first player in the world to obtain SSS level talent and has given the reward of everything atlas.

Even if you pick it out alone, it is no less than an SSS level talent.

"Organic life contains more or less part of phosphorus, which is one of the important components to promote teeth and bone collaterals. The easiest way to extract it is... Clam?" Tang Zheng was stunned when he saw the last line of words.

The refining method is very magical.

Urine distillation

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

Put the black residue in a wet place to decay, and then add a certain amount of fine sand to mix for secondary distillation.

This time choose to collect evaporated water.

When the water solidifies, it forms a white yellow solid substance - phosphorus.

“emmm……”

Although it sounds very mischievous, Tang Zheng checked the Encyclopedia of the atlas.

In the long river of human history, the person who first discovered phosphorus really tried this method

But the reason for refining urine is very bullshit

It's like the first human being to refine gunpowder. He just wants to see if this material can refine the elixir of immortality.

The idea of refining medicine first committed the crime of greed!

He thought there was a small amount of gold in the urine. Otherwise, how could it be light yellow?

As long as the urine is evaporated, the remaining solidification must be gold!

As a result, gold was not found, but the value of the elements found was more than the wealth brought to him by gold!

It can only be said that human beings are a very magical species, but it is precisely because of these wonderful ideas and bold attempts that they have created countless prosperity of modern civilization.

Tang Zheng looked down at his crotch

It's really not possible, but it's not impossible

This is called dedication to civilization!

Civilization, civilization, how can we count the three abuses?

Not shabby!

Fortunately, when Tang Zheng was about to devote himself to science, he caught a glimpse of the second half of the document and saw another phosphorus extraction method.

Bones.

Of course, this extraction method is that after the successful extraction of phosphorus by urine extraction, more people began to study this substance and found a more convenient method.

The extraction principle is almost the same as that of urine extraction, but the bone must be ground into slag, and then the water in it must be evaporated dry.

Just do it.

Tang Zheng rushed directly to the pasture and caught an ostrich.

Three times, five times and two times to help it complete the physical transcendence. The ostrich meat is thrown into the item column for preservation. After the bone is shaved and dried, the meat is smashed with a thick iron rod, and then ground back dozens of times until it is broken into residue.

Put on the pot!

The bottom of the campfire was filled with firewood. The broken bones were thrown into the pot and fried until the paste smell floated out.

LAN LAN, who is learning more knowledge through the forum in the house, thought her master had pasted the dishes and ran out with her nose.

But I saw the master turn his back to her and burst out bursts of excited and deep laughter.

"Hey, hey, that's the feeling, that's the taste."

"Master, it's strange..." Lan Lan was afraid and went back to the house.

After frying all the water in the bone residue, a pile of black paste solid particles was obtained.

Tang Zheng thought and opened a picture guide to the dark cuisine.

[black paste particles (no grade)]

Description: it doesn't seem to have any value, but it seems that some substances can be extracted from it. You can try to put it in a wet place

……

It can only be said that the atlas of all things will drop God forever!

Even unknown objects can give some hints.

Tang Zheng has something to say about dampness.

The air in the lakeside cabin in the forest is very humid every day.

It's not good to be too wet. My body can't stand it. I touch it when I sleep every day. It's wet

Wall.

Fortunately, the constitution of Tang Zheng and LAN LAN has long been different from that of ordinary humans. For this moisture, it can be discharged from the body by itself through hair.

The bone residue was wrapped in a large piece of paper and placed at random at the root of a dense wood full of mushrooms.

It takes more than a few hours to wait for its decay, even according to the moisture in the forest.

Tang Zheng was not idle during this period and made a batch of glass plates with higher purity.

For more than a week, hundreds of quartz stones were hoarded by Tang Zheng and have been thrown into the self-made warehouse.

With the change of civilization, glass will be used more and more.

Make a batch first, so that when you need it later, you don't have to make glass plates on site. Even if it is synthesized in seconds, it's too grinding to take five at a time. It's far less efficient than taking ready-made ones directly.

Take out a glass plate and throw it into the synthesis table to directly make a transparent curved neck bottle.

[curved neck bottle (excellent grade)]

Description: it can better retain the evaporated liquid for you.

……

From the appearance, it looks like a large teapot, except that the mouth of the ordinary teapot is upward, while the mouth of the curved neck bottle is downward.

After the top material delivery port is sealed, the liquid distilled from the fire will flow out along the downward spout.

In a few hours.

Tang Zheng took the rotten bone residue and opened the paper bag. There was a stench of decay.

"Everything is for civilization!" Tang Zheng took a deep breath and immediately held his breath. He threw the rotten bone residue into the curved neck bottle and added a handful of fine sand.

Fine sand contains silica, which can blend well with bone residue after heating in high fire to purify phosphide with higher purity.

Set up a small campfire, put it on it and start baking with a high fire.

In the direction of the spout, a small pottery pot is placed to collect the phosphorus produced.

After the fire heated for a while, it was obvious that the inner wall of the curved neck bottle was covered with a layer of white mist.

With the continuous baking, the pot mouth began to slowly overflow white viscous liquid.

Drop by drop fell into the pottery pot.

The process lasted about half an hour.

Finally, Tang Zheng got liquid phosphorus from less than half of the pottery pot.

The liquid that is as like as two peas and yellow is very similar to that of a man.

However, its internal particle structure is very clear. When the temperature drops down, the pottery pot becomes a grain of off white fine sand.

"Master, are these salt?" Lan Lan walked out of the house and saw her master holding a pottery pot watching in the sun. She came forward curiously and poked a small head.

As soon as I got close to the mouth of the pottery pot, I pinched my nose, and my tears were smoked out.

"What is this... It stinks!"

"These, these are precious." Tang Zheng smiled mysteriously.

Lan Lan looked at him and his eyes became strange.

"Master is a little strange recently..."

"It's not strange. It's dedication to science and struggle for civilization."

"So you have to giggle with these smelly things."

“……”

Gave Lanlan a brain collapse and let her go to the house to continue her study.

With the first production scheme, the subsequent production and synthesis of phosphorus will be much more convenient.

Just throw the fresh bone into the synthesis table and input 'phosphorus', and the product can be successfully obtained.

"Next, the extraction of manganese."

Manganese belongs to metal minerals. Manganese ore layer should be found.

In fact, in the periodic table of elements, the distinction between various elements is very simple.

In addition to the "arch" element, other metal elements are next to the gold character, next to the gas character are gaseous non-metallic elements, and the production of elements next to the stone character is slightly more complex, and some can be purified from the stone ore.

Some require chemical reactions.

For example, carbon is generally extracted from burned wood and raw coal.

Tang Zheng first asked several leaders of the "natural selection" tribe about the origin of manganese ore, and all the answers were "never seen it.".

In desperation, he had to open the forum and search.

There are very few related questions, only a few posts.

It seems that most players at this stage have not reached the time to contact manganese ore.

However, one of them still gives Tang Zheng a lot of information value.

[brothers, look what I found? Manganese ore layer! This wave has made a lot of money!]

Click in and have a look. The player took and uploaded several pictures.

In the picture, the mineral pile is in the shape of thin column and needle tip, with black color and bright semi metallic luster.

Click on the atlas and have a look.

[manganese ore (excellent grade)]

Attribute: Group 7b element of the fourth cycle, rising star of the semi industrial era and one of the main minerals for steelmaking. It can also be used in battery, printing, soap making and other industries.

Civilization limitation: players who need to enter the iron age can mine. The tools required for mining are made of steel.

Description: good steel needs good manganese, but only if you can dig the hard guy.

……

Some people in the Post said that they were awesome, while others expressed disdain.

[manganese ore is useless. It can only be mined after the iron age, and it also needs steel tools. Infinity is equal to nothing.]

[landlord, run away quickly. Be careful to be watched by high civilization players. I'll bring you all back to the mine.]

The player who posted the post didn't seem to give up and replied one by one.

[no, excellent stuff. Really nobody wants it?]

[no, no, I'll pack the coordinates for sale, and a big man will buy them!]

[please, I'm running out of money to eat. A dog coin tribe robbed me a while ago and robbed me of all my money. Now I rely on a virtual coin produced by my mobile phone every day to ensure the subsistence allowance, and even the civilization process is blocked... Let's buy my manganese mine coordinates...]

……

In fact, manganese ore is not worthless.

It's just that civilization is stuck here.

It's the same as when you cross back to the primitive tribe and hold a mobile phone.

There will be no signal tower and no electricity.

When the battery in the mobile phone runs out, it is a piece of junk.

Is it civilized?

Nature is one of the top products of modern civilization.

But is it valuable?

No,

The same is true of manganese ore.

At this stage, most players have just entered the bronze age, and the iron age is still far away.

Not to mention manganese ore that can only be mined with steel tools after entering the iron age.

However, this thing is of great value to Tang Zheng.

After thinking about it, Tang Zheng hid his ID and scratched words on the light screen.

[brother, are your manganese coordinates still there.]

Soon, the other end replied.

[yes! What can I do for you, brother!]

[make an offer.] Tang Zheng opens the door to the mountain road.

It's almost past 12 a.m. and the whole class can't eat it.

I! It's a dead line warrior!!
