When he wanted to return to the ground floor, Theodore killed three zombies with powers. They all had the same power as the ones he had killed before, namely poisonous smoke.
After ensuring there were no more zombies with powers on the first floor, Theodore decided to return to the ground floor and take turns with Cassian to clean up the remaining zombies on the first floor.
"I finally have some time alone. I think I should go into the sacred dimension and talk to the system there." Theodore had already decided to rest in the sacred dimension when the others went to the first floor to exterminate the zombies.
Used to jumping over the protective wall, Theodore easily reached the other side of the wall. He quickly walked down the elevator to return to the others.
At the bottom of the elevator, Theodore saw Cassian waiting for him there; he slowly approached him.
