KAN dislikes KWAN's behaviour very much. He then decides to find HUNG again so as to learn kung fu to defeat KWAN.

On the way, KAN and LOY meet the last eunuch of the Ching Dynasty. They find that his martial art is very good. They intend to have him to be their teacher. He originally refuses. Later, in view of their sincerity, he accepts them after- testing their strength.

The eunuch declares that after learning his kung fu, there would be special changes in their body. However, they ignore the result and insists on learning his kungfu.

When CHOY SUN SIN knows that learning the special kungfu requires sterialization, he stops them immediately. When KAN and LOY know that, they requests the eunuch to release them. The eunuch knows that he cannot force them to learn his kungfu. Therefore, he gives them two bloody frogs which would make them stronger and leaves them afterwards.
