Three Needles Kill the King of Hell

Kyoto, Airport Expressway. In the back of the taxi, Xu Mu was sitting by the window, with his phone screen on. An anonymous message with only one sentence - "Your father died in the same way back then." He stared at the line of words for a long time, then turned the phone over and clasped it on his lap. Master Liu Chengyuan died in Kunlun Mountain, and Su Tianheng personally slapped a gold needle engraved with the word "death" into his chest. That was three years ago. But this message said "your dad." Xu Mu was raised by his master since he was a child and has never met his biological father. Master only said: "Your father was killed by someone. Don't ask who it was. I will tell you when you learn the eighth turn." Master did not wait for that day. Outside the window, Kyoto's skyline was looming in the morning fog. The taxi stopped in front of an old unit building. Professor Zhao's home is in Xicheng District, Kyoto. There are several piles of old books and two pots of half-dried asparagus bamboo piled at the door. Xu Mu knocked on the door. Professor Zhao was wearing a gray sweater that had been washed white. He let him into the study room, took out a tin box from the bottom of the bookshelf, opened the lock, and found yellowed document bags neatly packed inside. "Your master has kept it with me for forty years. He didn't dare to send it or pass it on. He said he had to wait for you to pick it up in person." He took out the bottom brown paper bag and sealed it with wax. There was a vague fingerprint on the wax. Xu Mu opened the seal and poured the contents onto the desk. A few pages of yellowed medical records, a coordinate map of Kunlun Post, and a black and white photo. In the photo, Master is wearing a military uniform and standing in front of a sign that reads "Kunlun Border Guard Post". Next to him is a man in a white coat.
