How To Be A Demon lord: The Former Hero's Journey As A Demon Lord! - Chapter 171 The Holy King

Seo Tae Hyuk, jailed after being falsely accused.

I don’t know why I die, I don’t know why I live.

Divided hunters die of loyalty,

The witch who plays with emotions dies of love,

Cautious fortune-tellers die of trust.

The thief who steals everything has nothing,

The visionary who created everything never existed.

The traveler fell on his way home,

The twilight giants rest before dawn.

Lawyers sacrifice for order,

Judges forget the law.

The sleepless sleeps in the dark,

The corpse collector lay in the coffin.

We are guardians, and a bunch of poor creatures who are constantly fighting against danger and madness.

This journey is life and death.

While drowning was inevitable, they had struggled.

This is the worst of times, this is the best of times.
