In an instant, a group of people collectively petrified.

After a long time.

A cry of exclamation came out leisurely from the huge forest relic trees, circling straight into the sky.

"Fuck!! Was that person just a low-key stalker?"

noon.

【Ding!Congratulations on your successful 'Steel'!Iron Age civilization progress (1/8)! 】

[Because you are the first player in the world to make 'steel', you will get the first reward - 100 fine-grade fertile soil! 】

Tang Zheng waited eagerly beside the furnace.

Accompanied by two clear beeps.

He harvested a steel block with a grayish black luster.

In the native world, the steel that humans usually see is a grayish-white metallic gloss, which looks clean and comfortable.

But it's all polished.

The steel that has just been made is only slightly brighter than iron.

A large piece of steel started, and a heavy and heavy texture came.

【Steel (Excellent)】

Properties: A high-strength and high-mechanical material, with which you can make more city buildings!

Description: It has witnessed human beings from thatched cottages to high-rise buildings, from swords and slingshots to guns, vehicles and ships.It is a unique pioneer in advancing the development of human civilization!

……

After reading the description, and then looking down at the small steel block in his hand, which was stumbling in shape and not at all beautiful, Tang Zheng felt a little emotional for a while.

It took 27 days to finally go from a pair of bare hands to now owning steel.

Just 27 days and nights span thousands of years of human civilization.

This small steel block in his hand is not heavy, carrying the heavy responsibility of the rapid development of human civilization.

The birth of steel was around the Middle Ages, and its appearance was a good substitute for iron products, especially in the advancement of civilization in urban construction and mechanical tools.

It is also in the hundreds of years since the birth of steel that more and more technologies and civilizations have been continuously pushed to higher levels.

The reason is because of the rust of iron products.

In the air containing a small amount of moisture, iron will be oxidized and decomposed to form rust.

Once this substance appears, it means that the hardness of iron is greatly reduced, and it is easy to cause fracture.

In a humid climate, iron rusts at a rate...in just a week.

Even in dry climates, iron has a shelf life of only a few years.

With a shelf life of only a few years, what civilization can develop?

Living in a house that doesn't know when it will collapse for a few years?

A car that falls apart after a few years of driving?

A plane that suddenly crashed after flying for a few years?

Not to mention those large-scale scientific research instruments, the precise small parts are assembled together, and it takes a lot of time to manufacture such a machine.

And only for a few years?

The limitations of iron have caused human technology and civilization to be hindered for a long time.

At this moment, steel turned out.

It is not easy to corrode, and its density and hardness are higher than that of iron.

Construct a steel age with dreams as horses for human beings!

Cars, tall buildings, airplanes, and more and more civilizations were born explosively during this period.

In a trance, he returned to the small piece of steel in his hand.

Tang Zheng gently stroked its angular appearance, as if he was treating an old friend he had known for many years.

It is indeed one of the most helpful substances for human beings.

Tang Zheng took the small piece of steel back to the house and placed it firmly on a small wooden shelf as a souvenir.

The first steel material extracted by human beings in this other world will be kept here forever.

Maybe one day humans will find their way home.

Perhaps one day, the entire human army will be wiped out in this otherworldly land.
