Rebirth 85: the Old Lady Swept Away the Rebellious Son and Rebellious Daughter

I don't know if the author is too forgetful. When the first couple died, the second son and his wife came. Later, the heroine was reborn and said that the second son's wife died within two years of marriage. So how many wives did the second son have? In the previous life, the old couple died, and the second son wanted to buy the only valuable cow in the family to collect the bodies of the old couple (the other sons and daughters were ignored). The second son's daughter-in-law didn't object at all, she was honest and filial. As a result, the first thing the old couple did when they were reborn was to replace the second daughter-in-law! Because he dislikes the second daughter-in-law for being a sick child!
