章 1495: Pull out

After the zombie clones repeatedly injected the energy into the climbing vines, the natural energy was purified again and again.

Fang Heng then tested the effect of the purified natural energy.

Fang Heng frowned and stopped using perception, leaving the zombie clones to continue leveling up and gaining experience. He began to search carefully along every wall of the manor alone, looking for where the natural energy had decreased.

He checked the place area by area, starting from the hall to the second floor, and then from the second floor to the basement.

He found it!
