I Unlocked an AFK Map, and the Souls I Slay Overwhelm the Underworld

[System + No Female Lead + No Playing It Safe + Ruthless + No Goody-Two-Shoes + Data-Driven] The protagonist’s soul transmigrates into a cultivation world, where he activates an idle cultivation game System. [Exploration progress for the Sanyuan City map: 10%. Regional idle map unlocked.] [Killed Iron Fist Gang member. Cultivation +1, silver +3.] [First-kill reward obtained: Innate Primordial Sword Art.] [Innate Primordial Sword Art: A Qi Refining technique that condenses a strand of innate sword energy within the body. Once expended, it must be condensed again.] Besides idling, he can also earn cultivation points by killing members of hostile factions in the real world. So he idles while killing people. Before he knows it, he has fought his way through the Three Realms. From the Cultivation Realm to the Immortal Cultivation Realm, and from there to the God Cultivation Realm.
