Che Hou was no longer the past Che Hou. He fused with that ultimate divine weapon which was created through the efforts of several generations of the Che Clan by the refinement of countless divine weapons with the use of divine formations. Ultimately, the Che Clan suffered a backlash and the ultimate weapon devoured all of them before fusing with Che Hou, becoming the present him.
Because he could easily transform into different divine weapons, each of the divine weapon was him, they were also considered as his clones. Naturally, these types of clones were weaker than usual clones and their strength was a far cry from Che Hou's original body.
But even so, any of those divine weapons could easily destroy an ordinary deity. Those deities of the Qin Heavenly Divine Sect actually didn't even have any ability to resist. They were possessed and assimilated, becoming a part of Che Hou.
