Fang Jie was well aware of the strength of a Ghost Assassin, although the one he had seen was of Legendary Level.
However, since the name was the same, they were generally similar. It's just that the Ghost he had was a mutated one. It could be said that its Attack Power was not as strong as a normal Ghost Assassin's, but its destructive capacity was different.
As the Destruction Poison was generated, the Ghost Assassin also developed a special kind of deadly poison, probably to counterbalance the unique energy of the Destruction Poison.
The Skill indicated "Death Energy Poison," which was actually a deadly poison condensed through Death Power.
Indeed, it was a deadly poison, not just simply Death Power.
This poison targeted living beings, possessing extremely powerful lethality, but had little effect on Undead Creatures. This characteristic was similar to other Undead, but with much stronger lethality.
