I'm Really Not a Demon Lord.

In the previous life, my spiritual roots were inferior, and I wasted my time until I died, only glancing at the threshold of foundation building. After being reborn in this life, Zhou Wei holds the "Burning Soul Devouring Technique" and the "Secret Puppet Drawing Technique" inherited from the Immortal Lord of the Upper Realm, and possesses two top-grade spiritual roots. He had experienced the despair of lacking resources and being exploited by human beings. In this life, he vowed to live only for himself. The world of cultivation is dominated by the weak and the strong, with limited resources and competing paths. Zhou Wei understands this principle well. He does not believe in destiny, does not rely on others, only believes in the sky-burning flames and invisible soul threads in his own palm. The exercises can consume the spiritual power of all things to strengthen one's body, and the secret techniques can divide the soul and manipulate the human heart. Benevolence, justice and morality? But they are the yoke of the weak. The righteousness of the sect? It's nothing more than a fig leaf for profit. From being a minor cultivator in the family to joining the Immortal Sect, from seizing treasures in the secret realm to competing for supremacy in the realm, Zhou Wei has been making plans every step of the way. Loot resources, devour opponents, lay soul threads, and control the chess game. He will consume all obstacles in his way with burning flames; he will weave his own web of destiny with invisible and qualityless threads. This is a dark fairy road that only belongs to predators and manipulators. When the burning flames burn out the sky and the threads of soul cover all the worlds, all living beings will know what the true way of "self-interest" is.
