In his previous life, Zhang Xingzhi tested as an S-rank ability user with the [Evil Cultivator] ability at the superpower college entrance exam. Before he could even understand what it did, the Superpower Administration took him into custody. They dissected him, took samples, injected him with regenerative agents, and studied him on an operating table for seven whole years, until he died.
When he opened his eyes again, he had returned to three days before his awakening.
This time, he fled overnight and became an underground mercenary.
A soul banner that captures spirits and steals abilities, evil arts that turn corpses into an army, demonic energy that burns people as fuel: the abilities the Federation fears most became the sharpest weapons in his hands.
The Administration hunts him, the great families covet him, and the underworld fears him.
Zhang Xingzhi only wants to ask one thing: Are the people who dissected me back then still alive?
Good. I'm coming to collect.
