A virgin succubus?
After a moment's thought and considering that there was a creature capable of threatening his life, Bai Zemin decided to play it safe instead of trying to show off before Lilith.
He retreated towards the stairs until he reached the second floor and waited for the zombies there. His back was almost touching one of the walls and the left side of his body was against the corner where the staircase wall and the wall of the lower floor met; this way, he could prevent being attacked from behind, he could avoid receiving attacks with his damaged hand, and at the same time he would be able to react with his right hand immediately in case someone tried to attack him from the only possible angle there was.
