100 Days to Live: The Life-Spending System

In a world where spiritual qi has revived, Su Zimo is framed and gravely injured, with only a hundred days left to live.

But just then, a System suddenly awakens. And it's a life-consuming System?

As long as he spends his lifespan, he can upgrade cultivation techniques, realms, and divine weapons.

But I only have a hundred days left. How am I supposed to play this game?

Wait...

You slapped a mosquito to death. Lifespan +64 days.

You stepped on an ant and killed it. Lifespan +128 days.

You killed an immortal jellyfish. Lifespan +** years.

Years later, the demon race breaks through the barriers between worlds, and a great terror descends from another realm. Humanity is on the brink of extinction.

Su Zimo, who now possesses an infinite lifespan, strides through the air.

Facing the mighty experts of the heavens, he slowly clenches his fist:

"Everyone, this punch of mine has two billion years of power behind it. Who dares take it!"
