In the train control room, Gu Mian had a friendly exchange with the train conductor. He received a thin book titled "History of the Seven Worlds" from him, which was, of course, written on the spot. To express his gratitude, Gu Mian drew a perfect door on the wall outside the train control room. The conductor was moved to tears by the sight.
About half an hour later, thanks to the combined efforts of the conductor and Coach Che, the train's malfunction was finally fixed. With everyone's effort, the train finally made it to the ninth stop, "Haicheng City Film City."
When Gu Mian and his companions left, the conductor chased them to the platform, waved goodbye with tears in his eyes, and said, "I was delighted to have you as my guests. Please, don't come again."
Gu Mian nodded gratefully, responding, "Definitely next time," as he left the station.
