Not only was he forcing others, he himself was indeed being pushed to the brink.
He really didn't expect Li Hongjiu, who had been silent all along, to suddenly speak up. This moment of distraction clearly allowed the strange poison to take advantage, causing the situation to suddenly worsen and spiral out of control, making him feel like all his efforts were in vain.
After he got Li Hongjiu out of danger, on the way back, he couldn't help but check Li Hongjiu's physical condition, couldn't help but try to see if he could detoxify Li Hongjiu, but he couldn't even find where the toxic effects were in Li Hongjiu.
In short, he knew Li Hongjiu was poisoned but couldn't detect where the toxic effects were, couldn't see or touch them. Not to mention saving him, he didn't even know where to start, feeling like Li Hongjiu was fighting against something that didn't even exist.
