This is a different primitive world with shape-shifting Smilodons and “Kung Fu pandas”. When the night falls, the glowing totem pillars are the only light source for the tribe. As a senior engineer, Cinder Fire is amazed by the primitive people who dominate both the sky and the earth. But he wouldn’t panic, for he’s going to be the strongest primitive. Let the ancestral fire be awoken, for the glory of the tribe!
