The two fought side by side, together slaying the Sun Erosion.
Cui Zhen suffered the backlash of [Yin Yang Reversal], disabling the unity of his two avatars; beyond failing in Harmonization, his realm even regressed. Such injuries would take at least some time to recover.
Xie Xuanyi wouldn't make a move at such a time...
If one were to kill Cui Zhen, the best opportunity would be to wait for his advancement!
If Cui Zhen successfully achieves Harmonization, then the two could have a peak duel, a fair fight!
If the Harmonization fails...
A mere Yin God poses no threat to Xie Xuanyi. Naturally, there's no need to bother.
"You seem to know me quite well."
Xie Xuanyi didn't deny this.
He refused Chu Lin's proposal largely for this reason—
With Xie Xuanyi's current strength, killing the weakened Cui Zhen would be too easy, as simple as blowing off dust...
But if he truly did so, he would be considered inferior.
