Boom!
The battle between Arthur and Mammon already reached a degree where the whole place around them was completely devastated. The walls, the ceiling, and the floor were full of cracks and also showing some signs of collapsing.
The two were completely unstoppable in their battle to the point it was impossible for Shin to join them even if he wanted to.
Each of their moves was almost executed flawlessly. Even their skill and combat technique executions were perfectly linked together where their previous moves were a set up for their next attacks.
Whether it was a feint to bait their opponent or an impromptu counterattack, their moves would always have an immediate response for any kind of situation.
