Jiang Yi was exactly waiting to hear this from Mo Yao'er. As the only daughter of Mo Shen, Mo Yao'er was rather unruly. If she wanted to kill Qiu Bai—even if Mo Shen knew, he would at most reprimand her for it.
However, if Jiang Yi was the mastermind, things would definitely be different. Besides the possibility of being executed under clan rules—even if Mo Shen had a sliver of suspicion and once the armies of the Dwarf Race approached and demanded Mo Shen to hand over Jiang Yi, it would be equally bad.
"Mo Xing, you said that we shouldn't act on Tiger Subdue Mountain and that we shouldn't be the initiators? It's a good idea to let them instigate something. It would be best to have a few other races present to be our alibi, so that when we openly kill Qiu Bai and his men, the Dwarf Race would not have anything to say. Majesty Father will surely not punish us as well."
