After improving his swordsmanship, Su Xiao took out the White Dragon Essence. He planned to use the biological energy within it to improve his Blue Steel Shadow ability.
The Blue Steel Shadow ability had not improved for a long time. It was only one step away from reaching Lv.50. Once it reached Lv.50, he would be able to use a branch ability called Energy Interruption.
Su Xiao used the Devour Core ability and began absorbing the biological energy within the White Dragon Essence.
A stream of glimmering white energy surged out of the White Dragon Essence and entered Su Xiao's arm. It was then absorbed, converted, filtered, and purified by the Devour Core, ultimately becoming a stream of colorless energy.
The moment this colorless energy appeared, it was devoured by the Blue Steel Shadow energy within Su Xiao's body. The Blue Steel Shadow energy rapidly grew stronger.
Because the Blue Steel Shadow ability had not improved for such a long time, Su Xiao could feel that he could raise it by several levels this time without losing control of it.
Streams of biological energy surged out of the White Dragon Essence. Since the Blade Demon energy had already been sealed into the blade and transformed into his own power, he could activate the Devour Core without any reservations.
The Blue Steel Shadow ability had increased to Lv.50.
The Blue Steel Shadow ability had increased to Lv.51.
The Blue Steel Shadow ability had increased to Lv.56.
The moment this notification appeared, a crisp sound came from Su Xiao's hand. The White Dragon Essence shattered. It was easy to imagine how much biological energy was contained within the essence of a rank-seven overlord. Even so, after devouring all that energy, the Blue Steel Shadow ability had only risen to Lv.56.
