Zhou Ji, at heart, is still extremely ruthless. On his journey of martial arts cultivation, the countless Martial Cultivators who died at his hands are more than one could count.
As for Wen Ju, he didn't show much emotional change, but the way he looked at Su Chen was a bit indifferent. Wen Ju is someone who doesn't like trouble, so if you ask him to kill an ant, he's too lazy to bother. However, Su Chen's ignorance made him somewhat disgusted. The best outcome for such an ignorant ant, in fact, is death, to avoid wasting the Spiritual Energy of the Grand Cosmos World.
