Veteran Hu Bayi received a mysterious package left by his grandfather. In addition to a incomplete map, there was also a notebook filled with strange symbols. The last page of the note was written in blood: "It takes sixty years to reincarnate. The bronze door opens and the underworld spring appears. The living should not approach it."
At the same time, an organization calling itself "Yin Soldiers" is hunting everyone related to the Bronze Gate. In order to find out the truth, Hu Bayi teamed up with Fatty Wang, who was proficient in the secrets of Feng Shui, and the mysterious woman Shirley Yang, and embarked on a journey to find the Nine Nether Bronze Gate deep in the Kunlun Mountains.
They traveled through Death Valley and cracked the mechanisms in the thousand-year-old tombs, only to find that every ruin was warning visitors to turn back. When the three finally found the legendary bronze door, the relief on the door actually depicted the figure of Hu Bayi's grandfather. What's even more chilling is that the "shadow soldiers" chasing them don't seem to be alive at all...
As the countdown to the opening of the Bronze Gate approaches, Hu Bayi must face a cruel truth: only his grandfather returned from the expedition team that entered the Bronze Gate sixty years ago, and the current leader of the "Yin Soldiers" is his brother who failed to get out of the Bronze Gate that year. Will history repeat itself this time? Is the "underworld spring" behind the door the elixir of immortality or the entrance to hell?
