After thinking about it for a while, everyone understood Qian Laixing's true motives. Back then, old man Qian and old lady Qian were old to work and relied on Qian Laixing's parents to support them. They not only had to support two elders but also had to support two scholars.
Qian Laiwen was proficient in everything from eating and drinking to gambling, but not at reading.
If this happened in any other family, they would have discontinued his studies. But the old Qian couple thought that their son was very smart and would be able to pass if he studied. But he wasn't able to study well and relied on his parents. Therefore, if Qian Laixing really was a ruthless person, he would have every reason to persuade Qian Laiwen to kill them and then no one would be able to force his parents, and Mrs. You wouldn't have to work so hard.
