Li Baijin

There was a Senior Brother and a Junior Sister. One of them was transmigrated to this world and had cheats while the other was the reincarnation of a Great Emperor.
The Senior Brother wished to stay away from trouble so that he could live forever, but he was ruthless and crafty.
On the other hand, the Junior Sister wanted to go against convention and conquer the Nine Heavens. She was ready to slay all kinds of enemies.

A long time ago since ancient times, when the Xuanhuang had yet to condense and there weren't any orders, the vast world and hundreds of millions of space were in chaos. However, as time passed by, they gradually moved towards order.

As heaven and earth evolved, life flourished. A terrifying life appeared in the world at an unknown time. They called themselves Heavenly Demonic Beasts. They had strong physique, profound cultivation and especially the unique power that could restrain all beings. What was more terrifying was that they could rapidly improve themselves through devouring spirits of thousands of clans. Therefore, their appearance was akin to natural disasters, destroying one world after another.

Gradually the experts who could barely resist these Heavenly Demonic Beasts appeared. They eventually gathered together, and an earth-shattering supreme war broke out.
