After Everyone in the Building Was Murdered, I Used a Lifespan System to Solve the Supernatural Case

[Fake System] [Not Invincible]

A bizarre video knocked at my mind, and an entire building became a slaughterhouse for vengeful ghosts.

The world teems with the uncanny, and revived spirits roam everywhere, reaping human lives.

My only means of survival is an exchange System that uses lifespan as currency.

Sacrifice years of my life to glimpse the ghosts' murderous intent; spend the rest of my days to buy the means to break through.

In an endless nightmare of horrors, I gamble my own lifespan for a chance to survive.
