Immortal Emperor!

Win Yi, who inherited a billion fortune, accidentally travels to the Great Yu Dynasty and becomes a puppet emperor facing constant danger. As court officials fight for power and the people suffer greatly, he awakens a system that allows him to return to modern times if he becomes a legendary emperor, or inherit three hundred billion if he abdicates and is killed. Initially seeking an easy escape through opportunism, witnessing the hardships of the common people makes him realize the need for change. He abandons shortcuts, resolves to reform the court and care for the masses, and strives to govern the nation to realize his true value.
