Zombie

After another thirty minutes, the leader exited their meditative state as they opened their eyes. The injuries around the leader's body were still there but they were now less noticeable as some of them had already healed. 

The leader stood up from the zombie's body. The leader then kicked the dead body one more time before walking towards a corner.

It was the corner where the zombie emerged all of a sudden. 

The leader thought that it was strange that a zombie would emerge all of a sudden in an empty room that they already checked thoroughly. 

As the leader arrived near the spot, they surveyed the wall as well as the ground around it. After a few minutes, the leader noticed a slightly different surface on a wall. It was rougher and unlike the other part of the wall, it was not covered with moist moss.
