Light flashes filled Hao Ren's cave abode.
Zhen Congming had placed the chess pieces into the stone walls of the cave abode, forming a small array formation in which the chess pieces interacted with each other.
Traces of lightning flew into Hao Ren's acupoints like streams.
The entire cave abode was like a space in the clouds, and Hao Ren was immersed in the weak lightning.
The array formation pulled the surrounding nature essence and used it. Since the essence intensity in the valley was much greater than that on the land, Hao Ren's cultivation progress was naturally much faster.
The chaotic lightning was made up of pure five-elemental essences, and the traces of lightning energy created by the array formation was easier for Hao Ren to absorb than the heavenly lightning which he had to withstand with his body before converting and absorbing.
