[Invincible protagonist + longevity path + decisive and ruthless + fast-paced + no heroine + sword cultivator] Ye Changsheng transmigrates to the Tianxuan Continent, where the System raises his cultivation to the peak of the ninth level of Quasi-Emperor. [Ding! New good-for-nothing comeback mission: Host, go to the auction and bid for a second-grade pill.] Ye Changsheng scratched his head. I'm already at the peak of the ninth level of Quasi-Emperor, and you still want me to make a good-for-nothing comeback by fighting for a second-grade pill? [Ding! The peak of the ninth level of Quasi-Emperor is the perfect time to make your move!] [Ding! Mission complete. Reward for Host: one Emperor Weapon and one ninth-grade pill. Add points to power, speed, defense, fortune, and lifespan!] Ye Changsheng looked at the System's rewards and fell into thought... Actually, being a good-for-nothing isn't so bad! Many years later, Ye Changsheng breaks through to become a Great Emperor. Looking at the System's new mission, he falls into thought once more: I've already become a Great Emperor, so why do I still have to make a good-for-nothing comeback?
