Jiang Xiaoyuan saw Jiang Xiaoyuan's paintings in this time and space at school, and found that they were the same as her own business. When Qi Lian said that she did not travel through time and space, and that her own time and space was just a dream, she firmly did not believe it and was very excited.

Qilian learned that Jiang Xiaoyuan wanted to go to Mingguang Laboratory to find the truth, but he had no choice but to tell about Huo Boyu. He was worried that Jiang Xiaoyuan would follow in Huo Boyu's footsteps, but Jiang Xiaoyuan firmly believed that she would not be crazy.

After receiving a call from Professor Lu, Qi Lian received a photo with Noah from Professor Lu and discovered that the Noah in the photo was Xu Jingyang.

In order to find out the truth, Qi Lian and Jiang Xiaoyuan decided to go to Mingguang Laboratory overnight.

When Jiang Xiaoyuan and Qi Lian arrived at Mingguang Laboratory, they found that the laboratory was clean and tidy, not like it had been abandoned for six years.

Qi Lian saw that Jiang Xiaoyuan had injured her foot and wanted to send her away. Seeing that Jiang Xiaoyuan was determined to find the truth, Qi Lian asked her to stay and wait while he went to investigate.

After Qilian left, Jiang Xiaoyuan was frightened by the weirdness here. She followed the light to a laboratory alone, where she recalled what happened back then.

When Jiang Xiaoyuan woke up from participating in an experiment, she overheard a scene in which the staff mentioned the memory module but was scolded by others.After Jiang Xiaoyuan eavesdropped, she learned that those who participated in the lighthouse experiment thought they were playing a virtual game. In fact, the lighthouse experiment would tamper with the participants' memories.Jiang Xiaoyuan was very scared at the time. After asking Huo Boyu, Huo Boyu comforted her with other words.

At that time, Jiang Xiaoyuan believed that Huo Boyu's memory had also been tampered with. In order to be able to remember everything about herself, Jiang Xiaoyuan secretly hid a diary and recorded it through writing.

Jiang Xiaoyuan was discovered to have eavesdropped on the staff's conversations, and was later placed under house arrest and forced to sign a liability exemption agreement.Later, Jiang Xiaoyuan continued to participate in the experiment, and her waking hours became shorter and shorter, and her memory gradually became confused. Jiang Xiaoyuan did not want to be a lamb to be slaughtered, and did not want to become a madman like other participants in the experiment, so she chose to escape from the laboratory and fell into a coma.The place where she was unconscious was the place where she thought she had traveled through time.

After reading the diary she recorded, Jiang Xiaoyuan regained her memory and fell into a coma.Qi Lian discovered the situation and took him away immediately.Their actions were witnessed by the mysterious man in the dark.

Qi Lian saw Jiang Xiaoyuan wake up and listened to Jiang Xiaoyuan crying that she might go crazy if she could not go back to the past time and space. He comforted her and promised to stay with Jiang Xiaoyuan.

Worried about Jiang Xiaoyuan's safety, Qi Lian was contacting the doctor when he heard a noise in the house and was relieved to see that Jiang Xiaoyuan was fine.Jiang Xiaoyuan wanted to go home. Qi Lian comforted her to rest and promised to take her home when she woke up.Qi Lian stayed with Jiang Xiaoyuan all night and took her back home the next day.

On the train at that time, Jiang Xiaoyuan and Chen Fangzhou were chatting about science fiction movies. Now Jiang Xiaoyuan also knows that the past she misses is just a dream.Qi Lian wholeheartedly hopes to reduce the impact of the lighthouse experiment on Jiang Xiaoyuan, but Jiang Xiaoyuan does not want her memory to be erased.
