True Immortal Trial

If you want to become a true immortal, you must complete the supreme trial. How can a boy who has no money, no power, no family, no sect, and no background wander in the demon country to preserve himself, find his own path on the trial ground left by ancient times, and fight his way to a glorious road to become a true immortal on the road of trials in different worlds? Mortal settings, system flow tasks, and infinite flow routines. One trial story after another, wonderful adventures in the infinite small world! Each one is original (blind) created (edited)... Updated twice a day, occasionally brain-burning, trying to be as funny as possible. Comments are welcome!
