Zhang Lingzheng checked the pulses of Xie Jue and Fang Chuning, knowing who took the antidote. At that moment, he clearly informed Fang Chuning, knowing that as Fang Chuning's friend, he wished Fang Chuning wouldn't realize in the future that he missed the opportunity to save Xie Jue's eyesight when he could have, which would cause inevitable pain and regret. Without the antidote, Xie Jue's eyes are likely to go blind eventually, but how long he can maintain his eyesight is unpredictable. The remaining poison in Fang Chuning's body can only be expelled by himself, which is a helpless matter.
He does not have the ability to achieve the best of both worlds and does not need Fang Chuning to give him a hint. Zhang Lingzheng mentions that a small portion of the poison still needs time to be expelled, but overall, it's no longer a major concern, and there is no life-threatening danger.
