Returning to the Millennium, My Brother Secretly Replaced My Child and Then Trapped Himself in a Cocoon

[Rebirth + revenge + pretending to be a pig and eating a tiger + a slap in the face, a cool article] In his previous life, Xue Ruifeng had a successful career and a happy family, and thought he was a successful person. But when he was happiest, he was poisoned by his son. Only then did he realize that the person for whom he devoted everything was actually not his biological son, but his younger brother's son. When the two children were born, they were replaced by their younger brothers. What's even more despairing is that his own daughter has been tortured to death by that family of beasts, and he can't even look at her. Xue Ruifeng died full of despair. When he opened his eyes again, he returned to the day when his daughter was born. The younger brother secretly changed the child again and was very proud. Xue Ruifeng just smiled, thinking expectantly, how interesting his good brother's face would be if he knew that the person he was abusing was his own son.
