"Are you now... serving Ling Chenzi?"
Cui Zhen hesitated slightly.
The Undying Spring wasn't particularly precious to him.
At least, using it on Old Shi was absolutely worth it...
He didn't care about this strand of Undying Spring.
But Old Shi was right; compared to the Undying Spring, it's more important that this "assassination" plan doesn't have any slip-ups.
Given Ling Chenzi's realm, strength, and sharpness, he could very well discover Old Shi's anomaly. By deducing "Life Extension," he might infer the Undying Spring, and then figure out his presence, which would be disastrous. Everything he painstakingly prepared would be ruined. The Great Saint Mountain would revalidate the invitations and initiate an unprecedented internal purge.
By then, not only him, even Xie Xuanyi would suffer the consequences.
"Yes."
