Nezha had just returned from the replica world of the Investiture of the Gods, but he was originally summoned from the world of Journey to the West. After having experienced the God and Demon replica, he woke up with some memories of his previous life, such as Sun Wukong causing Havoc in Heaven.
"Yo, isn't this Nezha, the Third Prince!" Sun Wukong asked with narrowed eyes, his voice somewhat provocative, as if saying, "Come on, have a fight with me!"
Nezha pouted and huffed, "Stinky monkey, your temper is still as explosive!"
Sun Wukong and Nezha had fought before, and after thirty rounds, Nezha was defeated. It might have been that Nezha deliberately threw the fight, but if they were to fight all out, Nezha was not Sun Wukong's match.
Fortunately, the two of them had a fairly good relationship. Faced with Nezha's tease, Sun Wukong did not fly into a rage and strike.
