Rebirth of the Courtyard: Super Brain Deduction Kills the Whole Courtyard

18-Year-old Xiao Jun was reborn in 1959. His parents were killed, his sister was sold, his family property was taken away, and he was severely injured and expelled from the courtyard. The courtyard is full of beasts, and he awakens "super brain deduction", which can calculate physical trajectories and chain reactions in milliseconds. A fifty-cent note sparked a fight, and the enemy Yan Jiecheng "accidentally" crashed into a wall and died suddenly. From then on, he hid in the dark and used scientific thinking to design a series of "accidents". Scaffolding broke, gas exploded, oil pans collapsed and splashed... Everyone died unexpectedly, and the police determined that it was all accidents. There is no female protagonist, only male high-intelligence revenge, and a silent massacre is taking place in the courtyard.
