Rebirth: The Jade Pendant For Immortal Cultivation

Li Yang, who had excellent grades and a handsome face, was once the school's star. Nonetheless, a circumstance four years ago altered the course of his life!
Struggling to get a job, he looked at other people's faces unwillingly, nodded, and bowed. As a result of his distress, he agreed to join in an unknown treasure hunt.
Despite his initial misgivings, he unexpectedly discovered a treasure! And just when he felt his life was about to change, a few men dressed in ancient garb emerged behind him, and suddenly... that was it! He died right there and then.
But as he never would have imagined, his destiny had already changed the moment he discovered that treasure! Upon realizing that he had been sent back in time, he made a promise to atone for his previous guilt and to stop the tragedy from happening again with the opportunity at hand.
Unable to hold back his yearning to get stronger, he said, "Since the heavens won't let me, Li Yang, die and gave me a chance to be reborn, then I must make up for my past failures."
