Episode 4 recap: The Case of Gu Ji Ming is Shrouded in Mysteries.

Jiang Guang Ming took two signed books of Gu Ji Ming and left with Shi Luo. Shi Luo actually had many more questions, but Jiang Guang Ming's single sentence made him realize that he was the one being questioned by Gu Ji Ming, not the other way around.Gu Ji Ming searched online for details about the rainy night J murder case from a year ago, his expression somber. The handwriting on the postcard did not seem to be a man's, so to investigate further, they would have to go to Fanghai City. Jiang Guang Ming went home to pack, and her husband thought she was planning to move out, quickly trying to stop her.

Jiang Guang Ming got into an argument with her husband, and after it was over, she went straight to her room, and her husband regretted his actions. On the high-speed train to Fanghai City, Jiang Guang Ming quizzed Shi Luo, saying that while a good memory is not as good as written notes, some things need to be remembered in the mind in order to connect the known clues and find the right breakthrough for the case.

Upon arriving in Fanghai City, the police chief had already made prior arrangements, and Jiang Guang Ming and Shi Luo obtained their credentials before visiting Gu Ji Ming. Facing the two detectives, Gu Ji Ming appeared very calm, stating that the urban village mentioned in his novel was something he had dreamed about.

Regarding the postcard, Gu Ji Ming said he had no recollection of it. The questioning ended there, and as Jiang Guang Ming and Shi Luo were leaving, they witnessed Mrs. Su Zhen Zhen's wheelchair lose control and go careening down a hill. They steadied the wheelchair and advised the elderly lady to go down hills in reverse, as it was dangerous otherwise.

Back home, Su Zhen Zhen did not tell Gu Ji Ming about the incident earlier. Seeing two cups on the table, she asked if they had guests, and Gu Ji Ming lied that some friends from the literary society had visited, telling the lie without a hint of unease. Jiang Guang Ming believed that Gu Ji Ming had recognized Shi Luo, but she was perplexed as to why he would pretend not to know him.

Next, continue to investigate the postcard. After inquiring with the postal workers, it was learned that this type of postcard was mailed through a mailbox, and many mailboxes have now been removed, but there is still one on Seaside Road. The Seaside Hotel is conveniently located near the mailbox, so the two went to the hotel to inquire. They learned that when Tang Xun checked into the Seaside Hotel, he had injuries on his face. The housekeeper who was responsible for cleaning Tang Xun's room 201 at the time was named Jiang Na, but Jiang Na had left the job for a long time.

Shi Luo tried to contact Jiang Na using the phone number provided by other staff members, but the number was no longer in service. On June 21, 2018, Tang Xun checked into room 201 of the Seaside Hotel with a suitcase and a brown travel bag. Jiang Na had just finished reading one of his novels, so she recognized him.

In the evening, a colleague discussed the brown bag with her, suspecting that it contained at least several hundred thousand, as Tang Xun always carried that brown travel bag wherever he went. Turning the clock back to April 5, 2019, which was Tomb Sweeping Day, Gu Ji Ming returned to the magazine office and got the chief editor drunk. He then secretly deleted all the past submission records from the computer and emptied the recycle bin, effectively erasing all the submission records.

Gu Ji Ming woke up in the middle of the night, and Su Zhen Zhen was not by his side. She said she went to get a drink of water. Gu Ji Ming acted normal and pretended to go to the bathroom, but he actually went to the study to check the computer, where he saw the recent use was a group photo of the Literary Society members.

Remembering that he had told Su Zhen Zhen that Jiang Guang Ming and Shi Luo were his two friends from the Literary Society, Gu Ji Ming knew that Su Zhen Zhen had become suspicious. The next day, he invited Jiang Guang Ming and Shi Luo to the seaside, and without leaving any traces, he tried to extract information from Shi Luo. Jiang Guang Ming timely interrupted and took Shi Luo away.

Shi Luo actually had many more questions, but Jiang Guang Ming's words made him realize that he had been the one being questioned by Gu Ji Ming, not the other way around. Gu Ji Ming's strategy was not only to extract information but also to dispel Su Zhen Zhen's suspicions.

Once there was no one around, Gu Ji Ming used his phone to search online for news reports about the case from last year.
