To combat the monster before him, Chen Hai's Corpse Transformation Talisman should prove highly effective.
Judging by the fact that this creature still retains some human form.
Clearly, it must have died but, due to unknown causes, was contaminated by the malevolent energy, and ultimately transformed into the monster before him.
On that day, the Green-haired Zombie that was transformed into a pool of blood by Chen Hai's talisman had originated for similar reasons as the present monster.
After dealing with the Green-haired Zombie, Chen Hai went out of his way to look into some records and rumors about zombies.
Logically speaking, a zombie with green hair is just the weakest among such beings and should not be as strong as the one killed by Chen Hai!
After all, back then, Ye Cheng and others had deployed an army of over a thousand people and spent a month or two but still failed to subdue this creature!
