With the help of the sword, Jacob slowly rose to his feet. He frowned as he eyed the Black Silver Robe members, who were no longer humans.
He glanced at the dark mist rising from every corner and at the screaming crowd, knowing everyone would die if the situation continued. At that moment, the martial arts arena functioned like an arcane array, trapping everyone in it.
The Black Silver Robe warriors, on the other hand, were indestructible in the arcane array. Suddenly, an idea occurred to Jacob. The black mist was made of negative energy, which had the potential of becoming Jacob's resource of cultivation.
Moreover, the best way to deal with an arcane array was to find its core and annihilate it. Another way was to suppress it with an arcane array of a higher level.
At that thought, Jacob put away the Dragon Slayer's Sword and the blood demon's body.
