In this world where martial arts are respected and the weak are like grass, Lin Ye is just a low-level handyman with a precarious life.
Until he had a "dream". In the dream, he was the peerless demon who slaughtered the whole city and made blood sacrifices to the people. When he woke up from the dream, the frightening "soul-eating blood flame" lingered in his palm.
He suddenly realized that his dreams every night were a real world, and everything he obtained in his dreams - forbidden secrets, killing instincts, and even the power of gods and demons - could all be brought back to reality!
From then on, he opened his eyes in the deepest night and walked among the mountains of corpses and seas of blood in all the worlds. He is the "Heartless Sword Demon" who trembles in the world of Xianxia, the "Deformed Lord" who devours everything in the doomsday wasteland, and the "Old Walker" whispered in the Cthulhu mythology...
When the power from countless nightmares is added to his body, the so-called geniuses, saints, and ancient traditions in the real world are just slightly bigger ants in front of him.
"You think I'm a nightmare? No, I'm just... The king of all nightmares."
