The resentment is indeed troublesome, but if Wang Sheng wants to resolve it, he is not without power.
He could use his formidable strength to directly erase the souls that harbor the resentment, and with the souls gone, the resentment would naturally dissipate.
However, everything has its cause and effect; resentment arises from painful experiences.
If Wang Sheng forcibly eradicates these souls, even if it has nothing to do with him, he would still bear a certain karmic consequence.
Such karma would not have much effect on him.
But he is naturally unwilling to bear karma for no reason.
It would be better to simply suppress it, for by suppressing it, not to mention karma, he might even gain some merit if there is indeed a concept of merit in the starry sky.
After all, this resentment has indeed caused not insignificant casualties.
