Reincarnation Space: I Cultivate Evil Across the Heavens

[Main God Space + journeys through the myriad heavens + character growth + ordinary protagonist + decisive and ruthless, not invincible + not a wish-fulfillment story, read at your own discretion] Death isn't the end. Having no desires is... The young man Mo has now signed a reincarnation contract, traveling through the Myriad Worlds. To stay alive, he practices forbidden arts, devours living souls, absorbs yin to bolster yang, crafts corpse puppets, raises venomous insects, and makes deadly poisons... He once massacred an entire nation just to forge a Banner of Ten Thousand Souls. He has also awakened hope in those who fell into the abyss. He is arrogant, greedy, licentious, and bloodthirsty, yet in his heart he has an absurd “line” that his enemies cannot understand. Power is neither righteous nor evil, just like the sword in one's hand. Slaying monsters and vanquishing demons is the righteous path; slaughtering the innocent makes it an evil weapon. Whether one is righteous or evil depends only on one's heart!
