Tomb Robbery: Horse Riding on the Prairie into the Fog

In early autumn, I was riding horses and having fun on the Hangjin Banner grassland. I rushed into a thick fog and came out. In the distance, dozens of people with swords and spears were chasing people. Thinking it was the crew filming, I rushed over on a big horse - the group of people looked at me and stopped. I lowered my head and saw that their clothes were much too much compared to the Mongolian robes. This doesn't seem to be the crew. Trouble.
