Isn't this the thing you brought in?
When Huang Silang cried out with fervor, "Master Gui Daozi, aid me in Becoming Immortal," even Tang Wan, hiding to the side, was shocked.
You brought in this thing; your life is really something now.
And Zhou Li finally realized that there was indeed something going on between Huang Silang and Gui Daozi.
Gui Daozi was a quintessential master of controlling zombies, plus he possessed a modified version of the Path of Demons' art, so it was only natural that he knew the Entertainment Corpse Technique. In fact, if one were to overlook the comedic circumstances of Gui Daozi's death, he himself was not weak—in fact, he was quite formidable.
A body impervious to steel, on the verge of transforming into a Jiang Gui, coupled with numerous demonic enchantments and the ability to manipulate corpses. Such an existence, no matter where placed, would be considered elite, even a humanoid disaster.
