Fusheng decides to stick to Fenren to ensure that Fenren does not do anything wrong. He addresses Fenren as godfather. Fenren still thinks of Zhenzhen.

Fenren agrees to hold a class party on a Saturday. The party is to celebrate students with birthdays in that month.

Xinmei goes to school to fetch Mary home. Xinmei’s mother-in-law does not like Xinmei and objects to Xinmei marrying her son (Yong Fu) because she thinks that Xinmei caused the death of Yong Fu's late wife. In order to make Mary dislike Xinmei, Yong Fu’s mother (Xinmei’s mother-in-law) lies to Mary that Xinmei planned to ask Yong Fu to abandon Mary after marrying Yong Fu. Mary dislikes Xinmei after hearing this. She then behaves hostile towards Xinmei.

Mimi goes to Ling Ling Tang to find Xiaoling to ask her to be her teacher but Xiaoling brings up the question about the Fire Dragon. Mimi replies arrogantly that she is born with that talent. Xiaoling then tells her that she does not need a teacher since she already have the talent. Mimi is furious to hear this and quarrels with her. Xiaoling drives her out of Ling Ling Tang. Mimi waits impatiently outside of Ling Ling Tang for Xiaoling to accept her as disciple. Xiaoling calls Dingdang to complain to her about Mimi. However, Dingdang persuades her to accept Mimi. Xiaoling still feels that it is impossible to teach Mimi.

When Fenren's class is holding the party, the principal arrives to wish the students happy birthday. Fusheng finds it strange that the principal uses left hand to sign the birthday card when he is a right-handed. The principal invites every student to a storeroom in the school to get their presents. Every student follows the principal. In the storeroom, the principal uncovers a mirror. However, there is no reflection of the students in the mirror. Being curious, a student goes forward to touch the mirror but is pulled into it by an invisible strong force. Other students, except Fusheng, are also sucked into it. Fenren arrives and helps but he is also pulled into it. Fusheng manages to escape and he quickly goes to call Xiaoling. Peter suddenly appears and forces Fusheng into the mirror.

Xiaoling's car breaks down on the way to Fusheng's school. Mimi passes by and offers Xiaoling a lift. On the way, Xiaoling discovers that it is Mimi who damaged her car. However, she decides to give Mimi a chance to be her disciple.

Mimi buys yinyang glasses from Xiaoling as her powers are not strong enough to see dirty things. After wearing it, she manages to see that Fusheng's school is surrounded by yin force.

Xiaoling and Mimi are unable to find anyone in the building. Mimi goes into the storeroom and sees the mirror. She also sees no reflection of herself. Being curious, she touches the mirror and is sucked by an invisible force. The principal appears and tries to push Mimi into the mirror. Xiaoling arrives and manages to pull Mimi out by using her weapon for destroying evil spirits to hit the principal and the mirror.

They leave the room immediately and walk along the corridor of the classrooms. Xiaoling calls Dingdang and asks Dingdang about the mirror. She also asks Dingdang to come to Fusheng's school quickly.

There are many mirrors on the walls along the corridor. Xiaoling spots Peter in the mirror. She turns around but there is nobody. She turns back to the mirror and sees that Peter is going to beat them with a table. Xiaoling pulls Mimi away and pastes a paper charm on the mirror. However, Peter is unaffected and he hits Xiaoling. Peter then continues to hit both of them. Xiaoling pushes Mimi away and is hit by Peter instead.

Xiaoling stands away from the mirrors and observes how Peter hits Mimi. She discovers that Peter is actually hitting their reflections. The angry Mimi breaks a mirror. All the shattered mirror pieces reflects Mimi. Peter takes this opportunity and uses his sword to injure Mimi more. Xiaoling pulls Mimi away and gets injured instead. Mimi quickly turns into a cat demon and brings Xiaoling into a room, shutting the door behind her.

Xiaoling discovers that they are in a room where the walls are lined with mirrors. Peter injures Mimi seriously. He then tries to injure Xiaoling but to no avail. Finally, Peter is about to succeed when Tianyou arrives and draws the curtains, covering the mirror. Since there is no reflection, Peter is unable to continue his attack. Tianyou goes to look for him outside the room. Xiaoling and Mimi follow him.

Tianyou dissaudes Peter from bringing harm to others. Nevertheless, Peter refuses to listen. Mimi suggests breaking all the mirrors but this will cause all the people in the mirrors to die. Xiaoling and Mimi go back to the room and get down to work. Xiaoling tries to draw a laterally inverted talisman. Mimi sees and does not understand why Xiaoling is doing so.

Tianyou tries to provoke Fenren by bringing up Zhenzhen’s death, in the hope that the Fenren may wake up. Xiaoling hears these and knows that he is much better. Tianyou avoids Peter’s attack using his incredible speed. Fenren and Fusheng wake up and the former goes forward to hit Tianyou. Tianyou uses his watch (Peter is in the watch’s face) to block the attack. The watch drops onto the ground and Xiaoling pastes the talisman, which she has just drawn, onto the watch’s face. Peter is trapped. He then decides to destroy the world in the mirror.
