Zhou Heng chose to part ways with Zi Yingming, and Cha Sui also withdrew from this temporary alliance. Neither of them was quite accustomed to the Immortal Realm's cruelty and reality, and it was impossible for either of them to go from crossing swords with one another to shaking hands and making peace right after.
He might have been able to make peace with Zhong Gufeng, because he admired the other party, both for his strength and for his character. But Guo Yuhou and his ilk... with their poor character, Zhou Heng genuinely disliked them and had no interest in being hypocritically courteous to those he disliked.
If it really came down to it, he wouldn't mind shamelessly asking Huo Tian for help. The Peerless Heavenly Maiden's mere presence within a radius of ten meters of the Moonlight Lotus would have everyone else prostrating in submission. How could they then compete with him?
