In the World of Immortals, the Protagonist Should Be Unstoppable

A healthy young man transmigrates to a world of immortals and martial arts.

He thought he was destined to lead an ordinary life, but then a chime rang and he bound himself to the Demon God System.

Other people get to be upright, open heroes. It seems I'm stuck following the Demon God path? Of course, a transmigrator with a System is definitely the protagonist.

As the protagonist, do I really have to wait thirty years for the east bank of the river to become the west bank, play the pig to eat the tiger, and keep enduring and enduring?

No. If I can face-slap someone right now, I won't give them another second.

Now that's what a protagonist should be!

To repay a girl who helped me when I first arrived in this world, I casually solved a case and brought the demon to justice.

But now it seems that girl has fallen for me, and I'm freaking out!
