Under Li Mo Chou's threat, Yo Ko willingly died for Aunt Lung. Aunt Lung is very touched and Li Mo Chou also thinks they have a special relationship other than teachers and students, but currently Yo Ko does not understand romantic love, only willing to sacrifice to the good people to him.
The Ancient Grave was built by the Central God Ong Tiong Yang in such a way that the exit could be locked forever if there was an intruder. Yo Ko and Aunt Lung thought there was no way out and they were ready to go inside the coffin. It turned out that the coffin was a passageway leading to the secret room where the Central God inscribed the 9 Yin Book on its wall. In the secret room, they find an alternative map of the way out through the water.
(Note : This Ancient Grave belongs to Nona Lung's Grandmother, Lim Tiauw Eng, because he won one bet by deceiving the Central God. Lim Tiauw Eng's intention was for the Central God to live with him, but the Central God instead handed him the Ancient Grave, so Lim Tiauw Eng hated the Coan Cin school and taught his disciples to be careful of men)
Li Mo Chou's attitude softened as he needed the help of Yo Ko and Aunt Lung to jointly swim out through the waterway, until while they could escape from the pursuit of Li Mo Chou. Yo Ko and Bibi Lung restored the conditions around ZhongNan mountain. Aunt Lung is still groggy with the idea of going down the mountain, while Yo Ko has always wanted to see the outside world.
Meanwhile Li Mo Chou found his servant running away carrying the Book of 5 Poisons. His servant is Liok Bu Song, the son of the family he finished off in episode 1. He was furious and accused his student Ang Leng Po of being too weak to let him escape.
Yo Ko who knows a little memorization of the book of 9 Yin from the walls of the Ancient Grave, makes the Western Poison confused because it does not match what he memorized (because in PPR taught Oey Yong randomly). His mind went back to chaos and he left in a state of ‘kumat gilanya’.
The next morning when Yo Ko removed the blindfold and tootokan Aunt Lung, the teacher spontaneously thought Yo Ko was the one who did the last night. This change of attitude left Yo Ko confused. When Aunt Lung asked not to call her a teacher/aunt but a wife, she was spontaneously shocked and refused. Aunt Lung is embarrassed and heartbroken, so she picks Yo Ko up and leaves her.
After a long search, Yo Ko finally got the news about a beautiful woman in white with Ancient Grave kung fu that beat the priest, he immediately believed it was Aunt Lung. He was disappointed when it turned out that the woman had her face and kungfu far below Aunt Lung's. He was Liok Bu Song, Li Mo Chou's runaway servant.
