Since he was in no hurry, Huo Hai used Ghost Blade as a sparring partner. Ghost Blade was an assassin, and his moves were extremely dangerous, but trapped within an illusion, he posed almost no threat to Huo Hai.
Moreover, this man's own combat strength was not weak. He was, after all, a Fifth-Level Spirit Emperor, making him perfect for Huo Hai to adapt to battle against. Although Ghost Blade had closed his eyes and even completely blocked off his ears, Little Butterfly's illusions were instinctive and simply too powerful. Even so, her illusions still had some effect.
Under the cover of the illusion, Ghost Blade never realized that he had already left the small town. He even believed that he was still standing in the same place. Huo Hai could not interfere with the town for too long, either.
Within the illusion, Star Gu periodically set up spiritual power shields to block the aftershocks of their battle and minimize the fluctuations of their aura. Thus, Huo Hai and Ghost Blade fought without pause for five whole days.
Over those five days, Huo Hai used every Battle Spirit Art he was familiar with. Facing the exceptionally dangerous Ghost Blade, his various Battle Spirit Arts improved at an astonishing rate. Combined with Huo Hai's current comprehension, after merely five days, he had basically adapted to all kinds of Battle Spirit Arts. To improve further afterward, he would need a great deal of practice and combat.
Unfortunately, Ghost Blade, trapped in the illusion, never noticed how rapidly Huo Hai's strength was growing. All kinds of wounds had even appeared on his body, making him look exceptionally disheveled.
