One shock after another

There were many poisons in various worlds from ancient times and among them some poisons were limited to specific worlds.

In ancient times, one poison cultivator ventured into different worlds in the search of various poisons and to study them.

Due to his very high cultivation, he was able to venture different worlds without much difficulty and along with his long life span, he was able to venture 100 worlds and collected the information about various poisons in those 100 worlds.

With that data, he selected 10 poisons from all the poisons he collected and gave them a ranking from one to ten.

In that rankings, the five elemental poison was able to get a rank 5.

From that, one can understand how powerful that the five elemental poison was.
