At 3 pm, inside the building of Allerbmu, Pan Feng and Hwa Xiong led Xiao Tan as they cut their way to the top floor. The elevator that went from the ground floor to the 52nd floor was broken, and the entrance to the fire escape was broken down at the ground floor as well. But the elevators that led to the other floors were still usable.
They took trips up different elevators from the first floor to the seventh floor and then from the seventh floor to the tenth floor, and then they changed elevator again. Repeating this process, they finally reached the 42nd floor.
Along the way, they ran into two other mini bosses, but before Pan Feng and Hwa Xiong, they were completely defenseless, and they were cut down in less than three minutes. Facing normal BW Zombies was even easier; they were cut down like grass.
