Is Lifespan the Universal Currency? I Hold the Book of Life and Death!

Lin Chen dies unexpectedly. When he wakes up again, he discovers that he has arrived in a strange world. Everyone now has a mechanical bracelet on their wrist, recording how much time they have left to live. Lifespan has also become the universal currency. What’s more, this is a martial-spirit world, where everyone can awaken a martial spirit at the age of eighteen. Lin Chen was supposed to awaken only a low-grade martial spirit in the form of a battered book, but when the System appeared, it transformed his spirit into the supreme Book of Life and Death.

A billion years later, Lin Chen sits on the throne in the Hall of the King of Hell, gazing at the million-strong army of the undying before him. He can only sigh helplessly.

Sigh, controlling life and death in this world is pretty boring too.
