Underflow

The System gave humanity power.

Arthur Vance got zero.

When Earth is absorbed into the Cosmic System, billions awaken classes, skills, and limitless paths to power.

Arthur awakens as something the System cannot classify.

Class: THE NULL.

Every stat is zero.

Strength. Agility. Vitality. Intelligence.

Zero.

Weapons cannot make him stronger. Buffs cannot improve him. Healing barely works.

To the System, Arthur is an invalid file waiting to be deleted.

Then he starts dying.

Poison should kill him. Curses should cripple him. Bleeding should leave him crawling.

Instead, every negative status pushes his broken numbers somewhere they were never meant to go. The System is not increasing his power. It is underflowing it.

For a few terrifying seconds, Arthur becomes something impossible.

Every victory costs blood. Every fight leaves permanent damage. Every new advantage demands another way to suffer.

Now the most powerful survivors in Halden want him contained. A healer is beginning to understand that saving his life may require leaving him broken. And somewhere inside the Cosmic System, a correction authority has noticed an error that refuses to disappear.

Arthur Vance is not merely surviving the apocalypse.

He is teaching the System that zero was never the lowest number.

Perfect for readers who love brutal progression fantasy, tactical LitRPG, system-apocalypse survival, dangerous powers with permanent consequences, and protagonists who earn every impossible victory, Underflow is the explosive first novel in The Null Protocol.
