The Heaven-Killing Immortal Emperor

Legend has it that Heaven will choose a Daozi in each era, and Daozi is the son of Heaven. Daozi... "Stop, stop, stop, my parents are still alive and I have no interest in being someone else's son." Fifty thousand years ago, during the war between the heavens and Jiuyou, the Supreme fell. What no one could have imagined was that the countless confrontations between the Supremes in this world were all games played by God. The way of heaven is ruthless, and Taozi cannot have his own "love"... I have slaughtered all the heavens and killed all the Nine Netherworlds. Now that I have done this, I will kill all your Nine Desolate Heavens again. In my previous life, I was the Supreme Being, but in this life I am just a god~ Zhu Xian? No, starting from today, my sword will kill the sky!
