Heaven Civilization Salvation System

Chapter 4 Read to Save Civilization!
Fang Zhe sat by the empty porthole, quietly looking at the dark starry sky.

The giant space station orbiting Mars is slowly making its way.

The memories in his mind still made him feel a little uncomfortable, and he even suspected that he had traveled through time into the novel world.
-
"Mr. Fang, there is still no signal from the direction of the earth that you need"

Xiaohan, the artificial intelligence, was still chattering and reporting at the side. Up to now, he still cannot accept the terrestrial planet with a radius of 6378.137 kilometers and a circumference of 40075.7 kilometers in the third orbit of the solar system.

The world evaporated in a day, and there was not a single hair left.

If it wasn't for the system panel that only he could see was displayed in front of him after thinking about the system panel in his mind, otherwise all this would be unbelievable like a science fiction novel.

Withdrawing his frustration and calming down, Fang Zhe began to summarize the reasons for the failure of the first game.

The first is the lack of knowledge reserves. I don’t have any knowledge of wild survival, not to mention the most basic chemical equations such as cement making and gunpowder, not to mention the most basic chemical equations. .

In addition, Fang Zhe is also a literary school when it comes to farming and farming. He almost starved himself to death when he engaged in agricultural planting research.

If the system had learned this knowledge before entering the dungeon, it wouldn't be as confusing as when I caught it blind this time.

Finally, and most importantly, the primitive society still respects strength. After researching the farming technology that does not belong to this era, you should not be too eager to share it. Last time, there were only two younger brothers, and they were weak.

……

After staying in the dormant cabin for a whole day, Fang Zhe did not enter the copy in the system again, but took the conveyor belt to the library located in the center of the Mars space station.

In the personal learning system, there is no such ancient knowledge. In 2112, after the controllable nuclear fusion was solved, the technology began to explode. This knowledge can only be seen in the included Mars main library.

The library is extremely large. Fang Zhe randomly found a few professional books related to iron smelting and farming, and immediately checked them carefully. When he saw some important places, he would even take out the paper and pen he carried with him and write them on the book. Frantically memorized notes.

For several days in a row, Fang Zhe spent time in this intense study state. He forgot to sleep and eat. When he was tired, he would sleep on the desk for a while. Water, not a moment's time is spared.

This drive to study hard even attracted the attention of some researchers in the library who often came to look up materials.

"Sister Han, look how strange this boy is. Is it because his relatives are on the earth? The excitement is too great. Every time we come here these days, he is always there, and this strange person has been reading the book in his hand, head Didn't even lift it."

Opposite Fang Zhe, a petite girl muttered to the quiet woman with long hair and shawls beside her, with a jade-like complexion.I thought: Sister Han looks so like a national goddess, half of the people in the Mars library are pretending to be studying, but in fact they secretly look at Sister Han.

Even if you study hard, it's not interesting. After seeing it, you will take a second look. I didn't expect that the man on the opposite side seemed to treat us like air for a few days. He was really pissed off.

Install, you continue to install.

The quiet woman in a book of philosophy, when she heard what the petite girl said, raised her phoenix eyes slightly, and from the corner of her eyes, she just saw Fang Zhe writing in his notebook: Sulfur + charcoal + saltpeter in a ratio of 1:2: After the mass ratio of 3 is ignited, an explosive reaction occurs, generating the chemical reaction equation of potassium sulfide, nitrogen and carbon dioxide...

Blast furnace ironmaking is the main method of modern ironmaking and an important link in steel production. This method is developed and improved from the ancient shaft furnace ironmaking.
Although many new ironmaking methods have been researched and developed by various countries in the world, due to the good technical and economic indicators of blast furnace ironmaking, simple process, large production volume, high labor productivity and low energy consumption, the iron produced by this method still accounts for the total iron production in the world. More than 95%.
During blast furnace production, iron ore, coke, and slagging flux (limestone) are loaded from the top of the furnace, and preheated air is blown from the tuyeres located at the lower part of the furnace along the furnace circumference. The coke (some blast furnaces also blow The carbon in the auxiliary fuel (pulverized coal, heavy oil, natural gas and other auxiliary fuels) burns with the oxygen blown into the air to produce carbon monoxide and hydrogen. During the rising process in the furnace, the oxygen in the iron ore is removed, thereby reducing the iron. The smelted molten iron Released from the iron mouth.
The non-reducible impurities in the iron ore are combined with fluxes such as limestone to form slag, which is discharged from the slag outlet. The gas generated is exported from the furnace top, and after dust removal, it is used as fuel for hot blast stoves, heating furnaces, coke ovens, boilers, etc.
Finding so much practical knowledge made Fang Zhe's heart agitated. Going to the primitive world this time will surely show his ambitions and strive to create a dynasty for all generations.

Seeing Fang Zhe suddenly dancing and excited, the quiet woman smiled sweetly, revealing a glimpse of her beautiful face, she shook her head and said to the petite girl beside her, "You're really a weirdo, Xiao Fei, leave them alone. The news is that researchers will be recruited soon, continue to read our books."

"Oh~" The petite girl pouted, glared at Fang Zhe who was opposite, and returned her gaze to the review materials in front of her.

A week or so passed, and Fang Zhe, who was fully charged, took a deep breath and returned to his own cabin with a hint of anticipation.

"This time, I have memorized all the knowledge points that I should memorize! Whether it is invention, creation or farming, I will not be able to stop me. This time, I must have a good time in the primitive world!"

No, I should add some insurance, click on the system panel, take out 400 of the only 300 points, and buy an identity card of the son of the primitive patriarch.

The identity card of the patriarch's son jumped out of the screen, a faint white light passed by the bed, the slightly thin body gradually disappeared into the light, and the room returned to silence again.

"Drip~"

"The player starts to enter the copy..."

　I signed the contract today to send the contract, there is only one update, sorry~
