Xiao Jingchen, a poor ancient cartographer, accidentally embarked on a journey to find the legendary "Kunlun Dragon Vein" based on a dusty diary and a mysterious metal relic in order to clear away the stigma that his grandfather had carried for many years. He temporarily formed a team with Lei Zhen, a retired soldier with a complicated background, and Su Wanying, a female geologist with a mysterious identity, and went deep into the uninhabited land of the Kunlun Mountains. In this forgotten land, they not only have to face the dangerous natural environment and institutional traps, but also face the suspicion and betrayal within the team, as well as a mysterious armed team following closely behind them. As the truth is revealed layer by layer, the true face of "Dragon Vein" is far beyond their imagination, and it has completely subverted their understanding of history and the world.
