Zhai Tianyu and Zhai Heng would have attacked the warehouse next to the one they raided as well if they had the time but as soon as they turned their attention to the next warehouse that was beside the one from which they have already stolen, the guard who was in charge of patrolling arrived.
At first, neither of them moved but then the guard snapped out of his daze and shouted, " Thieves! Thieves are attacking the warehouse!" As he shouted, he fished out the bell that he was carrying with him, which was tied to his waist and started ringing as frantically as he could.
No sooner did he start ringing the bell, the servants and guards of the Liu family woke up and rushed out of their rooms.
