Chapter 215
Just after Chen Qi's entire group was full of materials, he was preparing to move towards Tang Zheng to express his gratitude.
But found that the handsome young guy had already left.
"That guy...I don't know which tribe it is from, he feels so fierce." Li Mu purse one's lip.
"Should you not be fancy to others?" Someone in the team jokes.
Li Mu was embarrassed and laughed, and recalled all his childish remarks just now, and his face flushed suddenly: "Don't make trouble...I don't like me..."
At this moment, a reminder sound popped up in everyone's mind at the same time.
[Ding! Congratulations to the player'low-key stealth' for successfully clearing No. 27 Forest Ruins! Refresh the fastest clearance! 3 minutes and 04 seconds! 】
"Wait..."
"Our forest relic...what is the number in the world?"
"e...it seems to be the first On the 27th..."
In an instant, a group of people petrified.
After a long time.
An exclamation came from among the huge forest relics trees, hovering straight into the sky.
"Fuck! What kind of low-key stealth person was that person just now?"

Chapter 99 Steel is released. The beginning of the cradle of human technology [ The second one]
survive for 27 days.
At noon.
[Ding! Congratulations on your successful production of'Steel'! Progress of civilization in the Iron Age (1/8)! 】
【Because you are the world's first player to make'steel', you have won the first prize-exquisite fertile soil 100! 】
Tang Zheng stood by the furnace eagerly.
With two clear prompts sounded.
He harvested a steel block glowing with gray black light.
In the native world, the steel that humans usually see is shiny with ash-gray metal, which looks clean and comfortable.
But it is all polished through processing.
The steel just made is only slightly brighter than iron.
I started with a large piece of steel, and the heavy texture came.
[Steel (Excellent Grade)]
attribute: a high-strength and high-mechanical material, with it you can make more urban buildings!
Description: It has witnessed human beings from thatched cottages to high-rise buildings, from swords and slingshots to guns, carts and ships. It is a pioneer in advancing the unique and unmatched development of human civilization!
……
After looking at the description, he looked down at the small steel block in his hand that was stumbling and not beautiful at all. Tang Zheng felt a little emotional for a while.
After 27 days, I finally went from a pair of hands to nothing, and now I have steel.
In just 27 days and nights, it spanned thousands of years of human civilization.
This small piece of steel that is not too heavy in his hand carries the heavy responsibility of the rapid development of human civilization.
Steel was born around the Middle Ages, and its appearance has replaced iron products, especially in the advancement of civilization in urban construction and mechanical tools.
It is precisely in the centuries since the birth of steel that more and more technologies and civilizations have been continuously pushed to a higher point.
The reason is that iron products are easy to rust.
In the air containing a small amount of moisture, iron will be oxidized and decomposed to form rust.
Once such a substance appears, it means that the hardness of iron is greatly reduced, and it is easy to cause fracture.
In a humid climate, the speed at which iron rusts...just one week.
Even in a dry climate, the shelf life of iron is only a few years.
With only a few years of shelf life, what civilization can be developed?
Living in a house that doesn’t know when it will collapse for a few years?
A car that fell apart after a few years of driving?
Flying a plane that has suddenly crashed in a few years?
Not to mention the large-scale scientific research instruments. The precise small parts are spliced and assembled. It takes a lot of time to manufacture such a machine.
Then it can only be used 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 has higher density and hardness than iron.
Constructed for mankind an age of steel with dreams as horses!
Cars, tall buildings, airplanes, and more and more civilizations were born explosively during this period.
With a daze, he returned to the small piece of steel in his hand.
Tang Zheng gently stroked its uneven appearance, his expression seemed to treat an old friend who had known each other for many years.
It is indeed one of the most helpful substances to mankind.
Tang Zheng returned to the house with this small piece of steel in his hand, and placed it firmly on a small wooden shelf as a souvenir.
The first steel material extracted by humans in this alien world will be kept here forever.
Maybe someday humans have found their way home.
Maybe someday, the entire human army will be wiped out in this alien land.
