I Loaded the Auto-Combat Ability

[Single female protagonist + not fast pace + semi-invincible, long-term development] Nan Zhu had to face a philosophical question on the first day he traveled to another world: when your body is better at fighting than your brain, are you stronger or weaker? The martial arts master marveled that he was a prodigy in swordsmanship, and he killed monsters that made the whole land wail in agony. The alchemists regard him as the chosen one. No matter how complicated the alchemy tools are, the timing of using them is terrifyingly accurate. The spies in the black market whispered that he knew how to save his life and would run away at the slightest sign of trouble. When the desperadoes talked about him, their legs became weak, saying that he never blinked when he killed. But the people in the market said that he was kind-hearted, always dealt with drunken gangsters and bullies, and used gentle words to persuade people to do good. Some people even worry that he has made too many enemies and is often plotted against. However, only Nanzhu knows the truth: he can't even hold a sword steady. Survival depends entirely on the automatic combat system that takes over the body at the critical moment of life and death: it's the one who cuts down monsters, it's the one who plays with props, and it's the one who runs away if it can't be defeated. It killed when it judged it was dangerous, and Nan Zhu couldn't control his hands at all; it stopped when it judged it was harmless, and he could only bite the bullet and reason with others. As for the "assassination", he actually stepped on a banana peel when he went out, fell down the stairs and broke his head. But no matter what, in this world where monsters are raging, this weird ability turns him from a snack of monsters into a hunter that makes all monsters fearful.
