The protagonist Fang Yuan was reborn before he was plotted by his ex-girlfriend's family. In order to avoid the recurrence of the tragedy in his previous life, he properly placed the valuables in the villa in advance, raised legal pets, and took safety warnings. The greedy Liu Ruyan family still forced their way in, but eventually suffered the consequences and encountered accidents one after another. Fang Yuan relied on complete surveillance and legal evidence to prove his innocence, make the evildoers pay the price, and successfully protect his own rights and interests.
