Lin Ye, a graduate student in the Department of History, embarks on a journey to find the truth about his grandfather's disappearance because of the photos of the Republic of China expedition team and the hand-drawn map of Genting Tiangong left by his grandfather. On the way, he met Ah Jiu, a descendant of the tomb keeper, and Lao Zhou, a glacier guide. The three of them formed a team to go deep into the glaciers of the Qinghai-Tibet Plateau, but they did not know that they were involved in a shocking conspiracy surrounding the "secret of immortality."
The Yunding Tiangong is suspended in a glacier crevice. The gilded palace hides a man in mysterious robe who has been frozen for thousands of years - the leader of the ancient alchemists. He maintains his immortality by relying on the "ice marrow" at the core of the Tiangong. After awakening, he can control the ice and assimilate living creatures. As the team deepens, strange threats such as ice worms, ice souls, and ice-faced people come one after another. There is also the intertwining game between Mr. Chen who covets the longevity liquid, the international expedition team pursuing research, and the mysterious "Immortality Society".
From the Glacier Palace to the Kunlun Secret Realm, to the ancient city of the Western Regions and the underwater palace of the East China Sea, Lin Ye and Ah Jiu repeatedly overcome life and death difficulties: cracking the three tests of the Trial Hall, destroying the Immortality Stone, stopping the "Eternal Life Plan", strengthening the Sui Lord seal, and gradually uncovering the secret of the Immortal's seal and the mission of the tomb keeper. The truth about his grandfather, the sacrifice of his partners, and the confrontation of forces made Lin Ye understand that immortality is never a gospel, and guarding the peace of the world is the real meaning. In the end, they took the lead in establishing the "Global Immortal Guardian Alliance". During the journey of inspecting the sealing point, they continued to write the legend of courage, responsibility and protection, and also laid the groundwork for a new unknown adventure.
