Feng Xi has figured out who might have taken Dong Yue. They transfer out the weapons using the troupe. Feng Xi brings weapons to exchange for Dong Yue. Feng Xi blows up all the weapons before he is caught. Pang Yu gets there in time to save Feng Xi from getting killed. Because the weapons were blown up, there's no more evidence of Feng Xi's crimes.
