How was the Fu Kunlun of Mai God destroyed?

The reason why the operator Kunlun was destroyed was to predict a prediction. Someone predicted that the Mongolian army would invade the Central Plains, and this prediction was misinformed to the Mongolian army. When the Mongols learned that Kunlun was a spy in the Central Plains, they sent people to Kunlun House to kill him. Kunlun, the linen operator, is a character in Jin Yong's martial arts novel The Condor Heroes. A warrior with strong martial arts, who is good at fortune telling.
