After Blackie returned to the attic, his injuries were already fully healed.
At the same time, his physical strength seemed to have improved significantly compared to before.
All of this was observed by the Valley Master of Immortal Burning Valley.
This ability... is truly something else.
No wonder he was told to hide his strength.
Not only does he recover from injuries, but he even gets stronger.
If the fight had continued, maybe the outcome wouldn't be so certain after all.
As for why Chang'sheng told Blackie and the others to hide their trump cards?
The first reason, naturally, was to avoid exposing their killing moves in front of the disciples of Immortal Burning Valley.
The second reason was because of the Nefarious Demon Region.
The seals on the Nefarious Demon Region were growing increasingly loose.
It's perfectly normal for a few remnants to be outside, and as the seals loosen, their urge to cause trouble only gets stronger.
