Seeing his actions, it was clear he was planning to flee.
Upon witnessing this, Zhou Chun urgently commanded the Thunder Python, Baibai, "Chase, we must not let him escape!"
When you don't kill a snake completely, it's very likely to bite back.
Today, in order to deal with the Green-Haired Sorcerer, Zhou Chun even used the Slaying God Technique.
If he allows this person to escape now, then other powerful Demon Cultivators will guard against him in the future, making it difficult for this ultimate move to have a surprise effect.
Moreover, the Green-Haired Sorcerer had already been hit by his poisonous needle and was just injured by the electrical light column spit out by Baibai, making this an excellent opportunity to kill him.
