Each Attack Increased My Stats, So The Next Day I Applied For A Job As A Butcher

What the story is about

Reborn into an ancient Chinese fantasy world, Chin Sha uses the Kill God system to grow stronger by killing—even while working in an army kitchen slaughtering chickens and fish. When he is forced toward the front lines, he turns to archery and discovers that his rapidly growing strength and system-granted skills can make him a formidable soldier.
