Forbidden Land Archeology Bureau

Nineteen years ago, the archaeological team went deep into the forbidden areas of Qinling Mountains, and Jiang Hao's father Jiang Yuanshan disappeared since then. Official conclusion: Accidental death. Nineteen years later, a text message from a "dead man" brought Jiang Hao back to Qinling. The text message had only one sentence: "Don't believe the first door you see." Deep in the Qinling Mountains, an ancient underground road that had been missing for hundreds of years was rediscovered. No gold or silver, no treasure, just an unlocked stone door. But the marks on the stone door proved that it had been opened from the inside. What's even weirder is that in the underground ruins that have been closed for many years, there are footprints of modern people, food packaging, and traces of recent life. When Jiang Hao found seven corpses, everyone discovered a problem: all seven people were on the run before they died. And the direction they fled towards was the stone door. As the investigation deepened, Jiang Hao discovered that his father entered the Qinling Mountains nineteen years ago not to search for ancient tombs. He was looking for someone who had gone underground earlier. And deep in the ruins, his father's name was actually left behind. A incomplete map then appeared. Outside the Qinling Mountains, there are six equally mysterious underground ruins. Six "doors". Six pieces of history that were artificially erased. Archeology is just their status underground. Looking for his father is just the beginning of Jiang Hao's journey. What is truly buried underground is a secret that has lasted for thousands of years. And some people have been waiting for nineteen years for this secret to disappear forever.
