That is to say, these evil demons won't attack the Three Realms; there won't be a large-scale conflict between the two sides.
It's not that they are afraid of the evil demons, but rather that the Ziwei Heavenly Court has not yet fully controlled the heavens and earth, and with insufficient accumulated strength, if a war were to break out, it would be extremely disadvantageous for the Ziwei Heavenly Court.
Now that they know the other party will not wage a large-scale war, they are, of course, much relieved.
However, Sun Wukong and Nezha did not fully believe the words of the evil demons.
Considering the evil demons are good for nothing but trouble, to fully trust the words of a demon would be asking for discomfort.
At this time, an evil demon looked at Sun Wukong and Nezha, smiling bitterly and said, "I've told you everything I know; can you let me go now?"
Sun Wukong smiled faintly.
The heart of the evil demon sank, suddenly having a bad premonition.
