Aldrey and Irene's figures disappeared from their spot and clashed using their arms. They blocked each other's strikes, followed by a rapid series of attacks and defenses. Although someone with lower or even the same level of cultivation wouldn't be able to follow their movements, Aldrian could see everything clearly.

It seemed Aldrey and Irene were training their martial arts without relying on elemental techniques. Aldrian could tell they were more or less on par, as they could block each other's attacks. His mother had much more agile movements, which made her troublesome to deal with, but his father had a stronger body capable of withstanding all of her strikes.
