Was the black-clothed man sent by Su Huanian?
If that's the case, the fact that the first trial's swordsmanship came with dice does make sense. After all, it wasn't a reward, but a case of Su He engaging in subterfuge.
Which means he hasn't received the rewards for the first or second trials yet.
After looking around, Su He confirmed there was nothing left in the meditation room and turned to leave.
There was nothing in the backyard either, all the doors were locked and couldn't be opened, even the door to the meditation room was firmly shut, making it inaccessible.
Returning to the inner yard, a quick search revealed a small box at the spot where the colorful giant python had been. Inside the box were a bottle of pill medicine and a handful of fine sand.
