While other assassins continued to fight, Arthur and his remaining enemies were simply observing each other. Force was out and so if Arthur wished for it, he could immediately kill Specter or One. But doing so would leave Arthur incapacitated after the clash as his muscles and bones would break.
As for the Assassins, Specter and Force could not abandon their position for Arthur could dash and kill any of the other assassins. A silent agreement was made between the three. The only way to win would depend on who wins on the respective battles of their teammates.
Force had long been rescued by the surrounding soldiers. But the other soldiers dared not interfere with the battle of the Dragon's Fang. Instead, many were rushing towards the gate as the explosions and gunshots were slowly rising in intensity. Soldiers equipped with Pseudo-Skeletons could be seen as they started rushing towards the gate.
