Lun Hui Leyuan

Traversing countless worlds, reborn through endless quests, a blood-stained pact forged a night of beheadings. A merciless blade swept across the seven paradises, scattering countless heads and transforming the hunter Su Xiao into a terrifying symbol. Yet, even as killing became a daily routine, life and death a minor matter, he could not forget the death of his parents. The sinister smile of the gray gentleman beneath his hat, the eerie totems rising from corpses, and the oppressive might of the ancient god in the darkness gradually revealed the truth of that year. Chasing the true culprit, carrying on the legacy of the extermination of the law, and restoring balance to the elements became his inevitable destiny. (Source: Tencent, translated)
