Immortality Begins with Becoming a Mountain Guard

[Cultivation system + Gou Daoliu + Light reasoning] I started with a miscellaneous spiritual root, and others laughed at me for being a waste of life. Zhang Tiezhu thought so. The sect is no match for a cow and a horse, and the world of immortality is too dangerous. Then find a corner and curl it up! Competitions between sects, treasure hunts in secret realms, competitions between geniuses... They all have nothing to do with me! Nip any risks in the bud and do whatever it takes to survive. Bite! If you successfully survive for one day, your life span will be +1 day, and your cultivation level will be +1 point...] One o'clock a day, a thousand years later, I will be honored.
