Wushuang and Ghost Face squeezed through the small ventilation shaft. The duct was very narrow, making Wushuang uncomfortable, and the large frame of Ghost Face felt even worse. As they climbed through, they passed directly over the outside of the vault. There were already more than thirty fully armed people outside the vault. In the middle stood a middle-aged gentleman. If Wushuang was correct, he was the Duke. The news certainly traveled fast.
They must have touched something inside or left something behind that was discovered, which alerted the Duke. The ventilation shaft could lead to the roof or the third floor. The roof was definitely out of the question.
Since the Duke had found them, there must be snipers on all five surrounding castles. If they went to the roof, they would become targets. So Wushuang followed the ventilation shaft to the third floor.
