My Phone Has an Immortal Cave App

Chen Mobai is just another high schooler in a cultivation world, his \"true spiritual root\" barely enough to scrape by, constantly outshined by privileged geniuses hogging elite resources. A future of grueling conscription looms unless he can somehow bridge the chasm of power. But a bizarre scratch from an old temple's turtle shell changes everything. Now, a mysterious \"Turtle Treasure\" app glows on his phone, a direct portal to a magnificent, second-tier spirit vein underwater palace—a forgotten immortal's abode teeming with unimaginable spiritual energy. With infinite cultivation at his fingertips, Chen Mobai can finally break free of his limitations, but the palace's ancient secrets and the app's enigmatic 'Agent' function hint at a destiny far grander, and more perilous, than mere immortality.
