Song Jin, a top game master struggling to survive in the doomsday wasteland, woke up and became the most bullied outcast of the wealthy Song family. In this family that values "filial piety", he is surrounded by mean and cunning elders: his grandfather who always looks at him with a cold eye, his second uncle who often punishes him by kneeling in the ancestral hall, his stepmother who puts chronic poison in his food, and his cousin who hides a knife in his smile and always wants to kill him. Everyone thought he was a useless lamb left to the slaughter.
Until that day, Song Jin found a line of mysterious game data emerging from his pupils: [Warning: You have entered the ultra-high-risk copy "Fengtian Song Family", and a large number of non-human units have been detected. ] His pupils shrank sharply - it turned out that these "elders", without exception, were all demons in human skin! The Song family where he lives is clearly a "hunting ground" surrounded by demons.
Fortunately, the instinct to be a master of the game is still there. Song Jin activated the golden finger of the [Demon Slayer Illustrated Book], and everything in front of him can be quantified, analyzed, and dismantled: the weaknesses of monsters, the hatred value of BOSS, and the triggering methods of hidden missions. He is proficient in "taunting monsters", "faking death to escape" and "back stabbing". He works step by step in a desperate situation surrounded by monsters. He is humble and submissive on the surface, but secretly prepares for the killing. He uses the intrigues among his elders to eliminate the monsters entrenched in the Song family one by one.
He pretends to be the most obedient and filial son, but secretly sharpens his sword. Those "elders" who wanted to eat him didn't know that they had already been included in the hunter's hunting list.
