He could be certain there was no one hiding in Old Duke Chong's room.
He could also be certain that someone had been treating Old Duke Chong before he entered the room.
The disappearance in such a short time could only mean one thing, and that is a secret passage!
There is a secret passage in Old Duke Chong's room.
But the entrance to the secret passage had long been sealed by Marquis Dongxiang.
Could it be that someone from Dongxiang Marquis Mansion used the secret passage to detoxify the Old Duke?
This speculation seemed incredible to Duke Chong.
Marquis Dongxiang had an endless feud with him, and was also coerced by him to leave the Capital City.
Although it wasn't life-threatening for Marquis Dongxiang, it made him toil on the road for days without any gain.
Would Marquis Dongxiang not vent his anger on the Old Duke and even secretly join forces with others to detoxify him?
Is that possible?
But apart from this possibility, he couldn't think of anything else.
