In the future, the earth is ruled by the super AI "Pangu". I, {Lin Feng}, am the useless son-in-law despised by everyone in the Su family. I am trampled under the feet of my vicious stepmother and publicly humiliated by my mistress. Who would have thought that by awakening the "Child of Luck" physique, walking to pick up clues, drinking water and meeting witnesses, and solving the case all rely on the "blind cat hits the dead mouse" luck critical strike! It is also equipped with an anti-routine crime detection system, the more outrageous the case, the more it will be upgraded! The AI misjudged the mystery, the stepmother's poisoning plot, the mistress's conspiracy to frame the case, and the dark researcher manipulated the AI... I used luck to clear the way and defeated the villain through counter-routine operations. I solved the case in a funny way while upgrading the system, and by the way, I captured the peerless heroine Su Qingyan. Who said that a good-for-nothing son-in-law can only eat soft rice? I decided to use the luck against the weather, and even turned the AI upside down, letting everyone know: the son of luck solved the case, outrageous but effective!
