Jin Shifu missed his ex-wife, Manyun, so much that Dong Mei played a track that his ex-wife often played, recalling the past dribs and drabs. What puzzled Master Jin was that Manyun's cause of death was unknown. Tian Laoqi's analysis is related to the "third young master", but this "third young master" doesn't know who it is. Sixth Master asked Old Seven about it, but so far it has failed.

Dongmei told Kim that Manyun was dead:

Dong Mei talks with Sixth Master Jin and tells him that the real cause of death of Mrs Manyun was killed by Yuan Dingxiang. In order to get the map of the arsenal, Yuan Dingxiang asked his men to pretend to be Japanese and kidnap Mrs. Man Yun, who was chased by the Japanese on the way. Yuan Dingxiang was afraid that Mrs. Manyun would be taken away by the Japanese and the map of the arsenal would be lost to the Japanese, so he killed Mrs. Manyun on the spot. Pengyuan Jin eavesdropped on all their conversations.

Sixth Master Jin called Yuan Dingxiang and said that he had the murderer of his son Yuan Zijie. Sixth Master Jin asked Yuan Dingxiang to meet him in Xiangmanlou and hand him over to Yuan Dingxiang.
