Signing In at the Mass Grave, I Became the Eternal Sword God

The cultivation world is divided into three tiers: the Eastern Domain, the Central Domain, and the Upper Realm. Every cultivator believes that your spiritual root determines your fate. Those without good spiritual roots can only toil for their sects as servants for the rest of their lives. The protagonist, Gu Huai, is a sweeper in the servant quarters of the Qingxuan Sect. Since he has the most useless mixed spiritual root, the inner sect's talented disciples use him as a punching bag every day. When the senior inner-sect disciple breaks Gu Huai's ribs and throws him into the mass grave behind the mountain to feed the wolves over a bundle of dry kindling, Gu Huai's consciousness begins to fade. That's when he binds to the Myriad Ages Sign-In System. He can sign in anywhere to claim rewards, and the more remote and out-of-the-way the location, the better the rewards, even surpassing those in the sect's main hall. He signs in for the first time at the mass grave and hits the jackpot: a Marrow-Cleansing Divine Pill and the Myriad Laws Divine Physique. Overnight, he goes from a good-for-nothing to a ruthless powerhouse capable of steamrolling the inner sect.
