Demon Slayer: I Transmigrated and Was Immediately Adopted by Akaza

【Ruthless Protagonist】【Feel-Good Story】+【System】+【Villain】+【No Saintly Morality】 From the start, Lin Gongche was hunted by evil spirits, and the moment he transmigrated, he experienced the taste of death. The one who saved him was an even more terrifying monster: Upper Rank Three, Akaza. Faced with overwhelming power, begging meant death, and running meant death, too. Lin Gongche chose a third path: becoming strong! He wagered his life for the chance to grow stronger. He fought evil spirits every day, and having Akaza break his bones became part of everyday life. Yet he drew power at a furious pace from the 【Martial Arts System】. The worse his injuries, the stronger he became! To cripple an evil spirit, he could endure the agony of having his shoulder bitten through and smash its skull with his elbow. To survive, he dared to stare straight into Demon King Muzan's plum-red, slit-pupil eyes without flinching. Akaza thought he'd found himself an amusing plaything, but then he realized this kid's growth and ferocity made him seem more like a demon than a human! “Senior Brother, didn't you say the weak deserve to die? One day, I'll become strong enough to kill you with my own hands!”
