Lin Shen carefully examined the content on the blackboard and realized it was merely a theory and not an actual skill that could be used in real combat.
In theory, Lin Shen indeed could not solve it, unless he directly overpowered with strength or dodged and backed away, but that wouldn't be considered solving the skill.

The four ladies of Ye Xing were even less likely to solve it since their specialty was not in countering or breaking skills; given their power of sound, they generally didn't need to engage in close combat, and their mode of combat was different.
