My dad's marriage into my family made me rich, and my fierce yet adorable older sister spoils m

Lin Chuan was reborn. In his previous life, he and his mother remarried into a wealthy family. He seemed to become a young master, but in reality, he was constantly abused and whipped by his adoptive sister. His stepfather even used his organs and blood to curry favor with the upper class.
When his mother remarried after his rebirth, he saw his younger brother kneeling before her and clinging to her leg. He realized that this younger brother, who had always hated him, had also been reborn.
Since that's the case, Lin Chuan kicked him, saying, "Good brother, you should enjoy this good fortune."
Looking at the dilapidated pigsty where they had been sent down, Lin Chuan knew he had to quickly find a way out for the father and son.
Lin Chuan: "Dad, would you take a free meal if I offered you one?"
Father: "You unfilial son! I am a university professor, even if my bones rot in the mud, I would never sell myself for personal gain..."
Lin Chuan turned around and went to find the village's shrew, Aunt Guan.
Lin Chuan: "Aunt Guan, do you want a man?"
Guan Hongying: "?? Yes!"
The seven daughters of the Guan family said, "...I've seen people sell their sons and daughters, but this is the first time I've seen someone sell their father."
Later, his father was so pampered by Guan Hongying that his complexion became rosy, and the two of them ate meat every day.
Father: "Hongying, you're really beautiful."
But he discovered that his seven older sisters seemed to be more than just ordinary people.
These adopted daughters that Guan Hongying picked up all seem to have unusual backgrounds.
The younger brother, who knelt down to follow her to her remarriage, was exploited to the point of unbearable suffering.
I'm sorry, little brother. In this life, he will live a healthy life, carrying the father who was killed by his younger brother!
