Immortal in a Hundred Days

[Humanity's struggle to survive] [Neither wholly righteous nor evil] [Ordinary mortal's journey] [Not monogamous]

He transmigrates to a continent ruled by demons and monsters, where the two races have usurped the land.

Humanity can find no place to live. Ascending to immortality seems to be the only way out.

He thought he would draw his sword and slay demons and monsters, but as soon as he transmigrated, the Immortal of Union seized an interest in him.

He gains a mutated spiritual root and the mission of saving humanity, but has only a hundred days left to live.

A demon woman: “If I eat you, I'll surely gain a great deal of power...”

“Wait a moment. I know a way to help you increase your cultivation tremendously...”

A fiend woman: “What a perfect candidate for a cultivation furnace...”

“Don't rush. My method works even better...”

A human Saintess: “For the survival of my people, I'm willing to sacrifice myself...”

“Hold on. There may be another way...”

You and I are ordinary people, born into this world.

With time running out, how will he make his way across the continent of demons and monsters? What will become of humanity?

I'm no good at writing a blurb. Please read the story...
