Slaying the Gods, with Tons of Cheat Skills for the Heroine

Jiudu was kicked into a God-Slaying derivative world and discovered a friend whose memories and powers were both incomplete. Jiudu knew how their story would end and had planned to stand by and do nothing.

But...

As time went on, more and more things happened. Those who should have died were alive. Why had Jiudu encountered a friend with amnesia? Who had sealed Jiudu's power? Who had kicked Jiudu into the God-Slaying derivative world? A whole series of questions arose.

A huge conspiracy surrounded Jiudu, but many people were there for Jiudu too.

From Jiufan Tianhua, I save no one; I rank among the Nine Lords.

Also, the female lead has lots of cheat abilities, and she is both god and demon.

Lord Jiudu, Yin Qingfu
