Actually, analyzing from a general perspective, Fang Wenhai did not make any wrong steps, he did not really make a wrong choice, at the same time, Su Bai and the others did not do anything correctly, at most, both sides were mutually countering each others move, making their moves one step at a time.
However, the final outcome relies on a little bit of luck, but in any accidental event, there are actually some inevitable existence.
What goes around comes around is actually used to suit the occasion, it was because Fang Wenhai was definitely not clean, his whole family's miserable experience and way they acted had portrayed his sins and selfishness. But who among Su Bai and the others were really clean?
They were all not good people, there was no need to speak of retribution, if one wanted to speak about retribution, it wasn't that there weren't any audiences who did not do any outrageous acts, but they were definitely as rare as phoenix feathers and qilin horns.
