288 Chapter 288 Soul poisoning hell grass

After taking a few steps closer to the jade case, Shun Long's evil smile became even wider as he thought to himself

''Hehe, it is really a stalk of 'Soul poisoning hell grass'!''

This was one of the most lethal rank 5 medicinal herbs that a poison master could use to concoct poison or an alchemist could use to create rank 5 'anti-toxin pills', the 'Soul poisoning hell grass'.

Of course, not only was this grass rare to find, but it was extremely difficult to use as well both for poison masters as well as alchemists, in order to refine it into deadly poison or 'anti-toxin pills'.

Shun Long knew that the more black lines a 'Soul poisoning hell grass' had on it, the higher the potency of the poison inside it would be.

At the same time however, the level of difficulty and the danger that one would face during the refinement process would be even higher.
