The life crystals he was talking about were the land resources that the Marine human tribe couldn't do without for their survival.
Lin Yi had studied it before, and the key was a special mineral element that only existed on land. It was never found in the vast sea, so it could only be imported from land.
Due to the existence of a certain radiation, this element was not only useless to ordinary humans, but also harmful.
However, for the Marine human tribe, which was eroded by the seawater day and night, it was the most important guarantee to maintain their lives. To a certain extent, this could be regarded as an example of the incomplete evolution of the Marine human tribe.
The crucial point was that this type of Life Crystal was rare even on land, and Jianghai city did not have it.
Currently, the only known way to obtain life crystals was through the 18 levels of hell!
"What happens if you cut off your supply?" Lin Yi frowned.
