Using multiple Combat Skills at the same time is no simple feat, requiring at least two conditions to be met.
The first condition is that the energy pathways of the Combat Skills don't conflict with each other. The second depends on whether the user can multitask, distributing their energy to carry out multiple intricate operations simultaneously.
The Redscale Chaos Blade Skill is inherently complex; old Brownscale can't use any other Combat Skills when employing it.
Yet the Fishman youth could also use the Wave Stepping Combat Skill at the same time.
When both Combat Skills were unleashed together, it appeared as effortlessly simple as drinking water.
The surrounding Fishmen were all astonished by the youth's "talent."
The oppressive power of the Redscale Chaos Blade Skill was terrifying enough, and combined with the mobility of Wave Stepping, it suddenly caused the Fishman youth's combat strength to surge.
