The fifth type of poison was a kind of poison with a form. What was a form of poison? it was a poison that was like water. Not only did it take the form of water, but it was also as heavy as Mercury. It was a poison that could be used by cultivators as a magic tool. However, this kind of magic tool was consumable. In other words, after using it for a period of time, the poison would become less. At that time, you would need to replenish it.
It could be said that each of these five poisons had their own characteristics. However, at the same time, these five poisons were also very domineering and difficult to deal with. That was why Zhao Hai had chosen these five poisons.
Not only did the poison Dragon sect provide Zhao Hai with the formulas of the five poisons, but they also provided him with the finished products of each poison and a certain number of ingredients so that cultivators could refine the five poisons themselves.
