From which novel did the character have the belief of " repaying kindness for kindness and revenge for hatred "?

This sentence came from the ancient romance novel,"Wives Blessed by Heaven". The plot is very exciting. The protagonist, Meng Zhen, is a girl who will not be bullied. In order to protect her own happiness and peace, she refused to give in even if her family was destroyed. She even pulled out a 40-meter-long sword, which is very domineering. Most importantly, she had always adhered to the motto of "repay kindness tenfold, repay enmity a hundredfold", which was why this sentence appeared. I hope you like this fairy's recommendation.
