Why Are You Crying When I Become the Richest Man After Being Rejected by My Parents?

Lin Fei traveled through time and became the second generation of rich people. It's a pity that the original owner suffered from ALS when he was a child and was abandoned by his parents. They took him back after his parents became rich. But instead of cherishing it, they abused the original owner, leading to his death. Fortunately, Lin Fei was bound to the rate of return system, accumulated wealth, overcame ALS, and bankrupted his parents' family. My parents and sister began to regret everything they had done to Lin Fei. However, Lin Fei will never forgive them and let them regret it for the rest of their lives.
