Upon hearing this explanation, Zou Feng immediately understood.
The Heart Demon Poison Oath sworn by Bian Yixia and Sun Kai was a separate matter from Song Sixing colluding with the Mountain and River Association to rebel.
A duel was a duel. Sun Kai hadn't violated the terms of the oath; he was, in fact, engaged in a one-on-one fight with Bian Yixia.
In short, no matter what he had schemed beforehand, he hadn't broken any rules during the duel itself.
Even Bian Yixia's current, clearly abnormal state must have been caused by some trickery arranged beforehand.
The methods were so brilliant that Bian Yixia hadn't noticed a thing before the duel began.
Therefore, if Zou Feng were to interfere, Bian Yixia—who had been manipulated into swearing the Heart Demon Poison Oath—would be the one to break her vow, no matter the circumstances.
