I Slay Gods, Demons, and Monsters. This World Is Under My Protection

Spiritual qi revival + no System + passionate action + cunning protagonist + decisive and ruthless

From the start, I become an S-rank wanted murderer, then turn around and join Bureau 749.

The spiritual qi revival on Blue Star is actually part of a vast conspiracy.

All of humanity are nothing but distant livestock, servants, and food for them.

When even the gods turn evil, what do demons and monsters matter?

Though I am not human, I am willing to protect humanity's last glimmer of hope, if only to repay the kindness of the people who raised me.
