Hong Zhong transmigrates to another world through a dream. He only wants to stay behind the scenes, make a fortune in business, and keep a low profile, but he is repeatedly swept into conflicts across the realms and forced into the world of immortal and demonic cultivation. Along the way, he conquers countless races of demons, immortals, and gods, becoming the mightiest being in the heavens.
At the time, a poem about the heavens went:
Old Demon Hong Zhong loves to swear brotherhood,
Wherever he goes, he makes a new brotherhood;
All beneath the four seas and eight wastes are his kin,
Truly, the greatest tyrant beneath the heavens.
Later, another poem was written:
His voice booms like a bell, his aura fills the cosmos;
He transforms heaven and earth, the universe without end;
The Old Demon's divine arts shatter ten thousand realms;
No one ever guessed he was impotent.
