Yang Yu was preparing his own [Sky-shattering Dragon Roar].
This skill can trigger the user's Dragon Bloodline, combining the five-dimensional attributes to launch a powerful attack, inducing a series of luck-based amplifications.
The [Sky-shattering Dragon Roar] is an adaptive must-kill skill, and it manifests differently with different users.
In He Meng's case, [Sky-shattering Dragon Roar] transformed into the must-kill [Dragon Transformation Wave], allowing her to summon a water dragon for attack and briefly transform into a small dragon for combat.
The cooldown for [Dragon Transformation Wave] is only five hours, but since she cannot transform back at will once in small dragon form, He Meng doesn't like to use this skill often.
While strategizing in the [Hall of History], He Meng constantly tried to develop [Dragon Transformation Wave] in hopes of finding a way to lift some restrictions, but progress was incredibly slow.
