Ding!

Su Mo immediately began to pay attention to the blue properties panel that had appeared in front of him.

Compared to the game's brief introduction, the system had a very detailed description of the ore and even involved civilization levels.

Su Mo went through the words in the description, and a thought suddenly appeared in his mind.

According to this Soviet astrophysicist and the subsequent research of the later generations, civilization could be categorized into seven levels.

Type 0 was the lowest among them and was only capable of using the natural energy from the plant such as coal, oil, natural gas, trees, etc. to obtain energy.

It was equal to an infant stage according to Kardashev's scale of civilization. This category of civilization was able to crawl about but could not walk, and was a civilization imprisoned on their planet.
