The two figures sped across the ocean as fast as lightning. Everything in Beihai Harbor had completely disappeared on the horizon in just a few moments.
The black-robed old man beside the Crown Prince Beitang Wangchuan followed closely behind the man in the Golden Mask.
Dense fireballs were constantly shot out from the black-robed old man's side, bombarding the person in front.
Meanwhile, the person in front kept releasing fireballs toward the back.
The two people's speed had already surpassed the speed of sound. When they flew close to the sea, they would hear loud sonic booms. Like being slashed by two invisible plows, the sea water rolled, leaving two white traces on the sea.
Occasionally, a fireball would enter the sea and explode instantly. The high temperature caused the water on the sea surface to evaporate into steam.
