The young master of the Lin family was born with extraordinary innate potential and only ever wanted to live a carefree, lazy life. By chance, he activates an Invincibility System. During the Spiritual Aptitude Ceremony, a former Immortal Emperor from his third life emerges and sets his sights on his younger sister. The powerful experts of various clans join forces, only to suffer a crushing defeat. He unlocks an instant-kill divine ability and effortlessly annihilates the Immortal Emperor. Later, he takes on disciples and unlocks a ten-thousandfold reward system. Within three years, the world comes to revere him as the Young Heavenly Emperor. His cultivation-through-sleep technique helps his younger sister break through, he casually produces an Immortal Emperor's sword, and he freely enters and leaves the family's secret realm without regard for its Saint-level guardians. Despite possessing heaven-defying power, he never deliberately shows it off, yet trouble always seems to find him.
