299 Vol4 Ch24: Grid of the Divine flame

Prometheus, also known as Suiren, limping as he walked up the crude but magnificent altar, the middle of which contained a cluster of flame. A burning, bright, golden flame. 

He was still limping as if with a broken leg, but his appearance had drastically changed.

The original ape fur that grew all over his body had completely disappeared, the shape of his skull had also changed to look more like a modern human.

It could be said that other than clothing, Prometheus was no different from any future human, and all of this occurred due to the golden flames on that altar.

Several years ago, the human apes were still savage and primitive, the structure of their society was also very loose, essentially no different from that of wild beasts.
