The System Was Idle at the Beginning, and I Suppressed the Demons and Troubled Times

[No heroine] [Decisive killing] [Destroying demons] [System] Shen Han traveled to the Wei Dynasty and became a policeman. At the beginning, his fiancée broke off the engagement and his martial arts skills were revoked. In this world, there are demons and monsters in troubled times, there are thousands of families, alien races are eyeing the border, and weird things are brewing in the dark. How should Shen Han survive in this troubled world? Fortunately, he has awakened the infinite hang-up system. As long as he kills the enemy, he can use it as a hang-up target.

Kill the skin-stealing demon and obtain the green talent [Skin-Seizing]. Hang up and gain 1,000 experience points. Kill Master White Snake, obtain the blue talent [Swallowing Heaven], and gain 3000 experience points in the idle system. … Unknowingly, Shen Han stepped to the top step by step. From a young catcher, he suppressed demons, killed foreigners, wiped out noble families, and became the great emperor of the world, ruling for eternity.
