This poison becomes a forbidden medication in the palace because once poisoned, it is not easily detected.
It is composed of powder made from a very unique poison insect, mixed with many other poisons. It is a slow-acting poison. Beastmen who have been poisoned with this will not notice any abnormalities in their bodies, but over time, the pain will mimic normal illness. The body will ache but appear peaceful, and when they die, their face will seem to blossom like begonia flowers, hence the name Red Training Begonia Drunk.
And even Imperial Physicians can't detect this poison through pulse checking.
So later, it was destroyed and banned, becoming a forbidden medication.
This poison was originally for palace and inner residence intrigues, but who would have thought it would be used on Duan Tingxuan.
"This... turned out to be Red Training Begonia Drunk."
