Bang! Bang!
Despite using their full speed, but Randy and David failed to follow the eleven people. The portal disappeared even before David and Randy could enter.
As for the sound, it because of Randy and David hit the wall behind the portal. When the portal disappeared, what awaited them was a wall. Fortunately, the others were below, fighting the beast and monster. If they were here, Randy and David would be embarrassed for their silly action, hitting their body to the wall.
Even without them on the top here, Randy and David were still embarrassed to turn their body back. Eventually, David turned his body as nothing happened.
Currently, David was in his transformation skill. All over his body shrouded by the black flame and there was a black crown right on the top of his head. If Randy's look in his transformation form was nowhere resembling of a human's face, David maintained his human face.
