Cultivating Immortality, Summoning the Fourth Calamity

I transmigrate to a world of immortal cultivation and unexpectedly bind to a System. I awaken the Cultivation Sect System, and from then on, I can roam this world as I please. Lolis and shota, I can have fun with them all! They never give up on any mission. Give them an order to chop trees, and they’ll take down an entire forest. That’s the Fourth Calamity. The undying, unkillable Fourth Calamity. Like the Sky-Blasting Gang, they leave nothing behind wherever they go, exhausting every last supply. If you dare make me your enemy, be prepared to be swept away.
