The End of the World? I Will Cut Down These Heavens with One Sword!

Time travel through death: Monsters massacre the city, and Daxia collapses! The heroes are divided, the superpowers are running wild, the scavengers are surviving, the strange beasts are showing off their evil, the ancient warriors are vying for supremacy, and the creatures are wreaking havoc - ridiculous! I am an immortal cultivator, my elixir can burn the sky, my talisman can calm the earth, no matter what technology, biochemistry, or all kinds of things in the world, I will cut them all with one sword! And all this is just a joke from the superiors.
