Lan's head is covered with black lines. Oh my god, she's going crazy. The girl in the pink gauze skirt is Lan's half-sister, named Mao Lizhu, who was born to the third aunt. Lan had also studied Chinese history at the beginning, and it seemed that the dynasty he was living in now had not been seen in the book, so it was probably made up. I just heard others tell me that this dynasty was the unification of the world, and the country was named Nanke. Lan once laughed to the point of internal injury, andrology,,, and if Nanke was turned upside down, wouldn't it be Conan? I had a vague feeling that there was some connection but I didn't realize it at all.
