Since the mine closure in the '80s, Hell's Gate has become an increasingly mysterious legend. Located in a remote area at the northernmost part of Russia, close to the Arctic Circle, the peninsula is rarely visited by people. Additionally, with the powerful Northern Fleet stationed there, it was difficult for the average person to get a glimpse of the place, adding a thick layer of mystery. Along with Bermuda and Heavenly Lake, it's regarded as one of the world's most enigmatic locations.
While Suming was studying in Huaxia, he had heard many legends about Hell's Gate, including materialistic analyses.
Some believed that the mine closure was due to hitting a magma layer, and the 'devil's' roars coming from underground were the sounds of flowing magma.
