When Li Mochou killed her parents and took her away, she was going to kill her but when she saw the handkerchief on her neck she remembered Lu Zhanyuan, and so she did not kill her. Lu Wushuang was clever; she knew that her life was hanging on a thread now that she was in Li Mochou's grasp. That witch goes and comes like the wind; she would not be able to run away, so she pretended to be obedient and tried to please her. Eventually the urge to kill the 'Scarlet Serpent Deity', who kills without blinking, calmed down. Sometimes Li Mochou remembered the hurtful events of the past and would summon Lu Wushuang and shout at her for a while. Lu Wushuang would put on a pitiful face and limp along. When Li Mochou saw her sorry look and after shouting at her and getting rid of her anger that would be it. Lu Wushuang pleaded to stay with her, and because she was just a little girl, Li Mochou did eventually allow her to stay. She buried her thoughts of revenge for her parents in her heart. If Li Mochou asked her about it, she pretended that she had forgotten all about them. When Li Mochou and Hong Lingbo were practicing kung fu, she would stand to the side and pass over swords and towels, tea and fruits, concentrating on the practice. She already had a decent foundation, when she watched them practice she noted everything, and when Li Mochou and Hong Lingbo went out, she would secretly practice. She would normally try to get in Hong Lingbo's favour. Later Hong Lingbo took advantage of the mood that Li Mochou was in and pleaded on behalf of Lu Wushuang. Eventually she became her disciple. A few years passed, Lu Wushuang's kung fu improved every day, but Li Mochou was still suspicious of her so did not teach her the most advanced skills. Even the intermediate skills were not passed on. Hong Lingbo took pity on her and would give her some pointers in secret. Although it couldn't be said that Lu Wushuang's skills were high, her skills were not low either. That day when Li Mochou and Hong Lingbo went to the tomb to search for the "Jade Heart Manual", Lu Wushuang noticed that they did not return for a long time, so she decided to escape and go to Jiaxing in search of news of her parents. Although she saw with her own eyes Li Mochou seriously wounding her parents, she had not seen them die; there was still a glimmer of hope. She held onto this glimmer of hope and went to find out the truth. Before she left, she thought she might as well go all the way, and took Li Mochou's book, the 'Five Poison Codex'; it was a copy of a list of poisons and their antidotes.
Her left leg was lame, and she hated those who looked at it. One day in an inn, two Taoists looked at her leg and she immediately shouted at them. The two Taoists did not have good tempers, so after a few words they used force and they started to fight. With her curved saber, she cut off their ears and agreed to meet them at Wolf Valley the next day.
That day when Li Mochou took her away and headed north, she and Yang Guo met each other at the entrance to the cave. They were both young, their faces had now changed; they weren't able to remember their encounter of years ago.
Lu Wushuang was full after she finished the second piece of roasted meat. Yang Guo used the light of the fire to look at her face, "Where on earth is my Gu Gu? If the girl in front of me was Gu Gu, and I was roasting meet for her, wouldn't that be wonderful?" He was deep in thought, and stared at her as if he was mad.
Lu Wushuang thought, "I'll endure your disrespectful stare for now; I'll kill you later in the middle of the night." She then returned to the stone house and slept.
In the middle of the night, she quietly got up; she went outside and saw Yang Guo by the fire not moving. The fire had gone out long ago. She went over to him and slashed him with her blade across his back. Her wrist suddenly shook, it started to ache; she couldn't hold onto the saber and let it go. She felt that the place she slashed across was like metal or stone. She became extremely frightened and leapt away, and thought, "Could it be that Sha Dan has reached the state of being impenetrable by blades and spears?" She moved away tens of feet, but Yang Guo had not chased after her. She turned around; he was still by the fire, not moving an inch.
Lu Wushuang was suspicious and she called out, "Sha Dan…Sha Dan, I have something to say to you." Yang Guo did not reply. She took a careful look, and saw Yang Guo's body had formed a circle, it looked extremely strange, she boldly went over and saw that it did not look like the body of a person, she stretched out her hand and touched him, it felt like the clothes were placed on top of a rock. She grabbed the clothes and lifted up; indeed there was a large rock below. Where was Yang Guo?
She stood there for a while and called out, "Sha Dan, Sha Dan!" She didn't hear a reply so she listened carefully; there seemed to be a snoring noise coming from the house. She went over there quietly and saw Yang Guo sleeping on the table that she had just slept on. His back towards her and he was snoring loudly in a deep sleep.
Lu Wushuang was angry, and didn't even think about how he ended up sleeping on the table. She immediately leapt forward raising her saber, and pierced into his back.
The saber's tip had plunged into flesh but she didn't feel any resistance in her hands. She heard Yang Guo snore a few times and then said in his sleep, "Who's scratching my back, don't, don't, I'm scared."
Lu Wushuang turned pale, her arms quivered, thinking, "Is this person a demon?" She turned around to run but her legs didn't listen. She then heard him say, "There must be a mouse on my back trying to steal my meat." He stretched out his hand to his back and took out a lump of meat, and threw it onto the ground.
Lu Wushuang finally breathed out and understood, "So that Sha Dan put the meat on his back and just now I stabbed into that, I've just suffered a fright for no reason."
She had failed twice to stab him and she hated him even more, she clenched her teeth and quietly said, "Rotten Sha Dan, see if I'm able to kill you this time." She dashed forward and raised her saber, then slashed down across his back. In the midst of the snoring, Yang Guo turned his body, the saber slashed down deeply into the wood. Lu Wushuang circulated her chi around her hands trying to remove the saber. Yang Guo pretended he was having a nightmare, "Mum, mum, the little mouse is biting me." His muddy legs shot out, the left leg striking Lu Wushuang's 'Crooked Reservoir' (qu chi) pressure point on the side of her body, his right leg landing on her shoulder sealing the 'Shoulder Well' (jian jing) pressure point. Those two points are two of two of the body's important pressure points. When those legs came out, of all the places to hit, they hit precisely those two places. Lu Wushuang wasn't able to move, she stood there, becoming a support for his legs.
Lu Wushuang was furious, although her body wasn't able to move, her mouth still could, she shouted out, "Hey Sha Dan, quickly move your stinky feet away." She just heard his snoring becoming louder. She didn't know what to do, in anger she opened her mouth and spat at him. Yang Guo moved his body; his right foot brushed across and struck her 'Large Bone' pressure point. Lu Wushuang's body immediately became numb all over, even her mouth wasn't able to open, the stench from his feet flowed into her nose.
