During an accidental treasure hunt in Panjiayuan, Beijing, antique enthusiast Chen Feng bought a copper box engraved with mysterious symbols at a low price, and discovered the "Fragment of Mountains and Seas" which recorded the secrets of ancient tombs and treasure hunting maps. As soon as the mystery of this ancient book was unveiled, he was approached by the unidentified explorer Zhao Yu. The two formed a temporary alliance because of their common goal - to find the ancient tomb in the mountains that contained the "world-controlling artifact" hidden in the fragments.
Going deep into an abandoned ancient city, breaking through dark passages attacked by swarms of bats, cracking deadlocks in tomb coffins, and crossing bottomless canyons... Life and death crises followed along the way. Chen Feng relied on his interpretation of the fragments to avert danger many times, but he did not expect that there was a deadly conspiracy behind Zhao Yu's cooperation. When the crystal ball in the secret room that can seal ancient monsters appears, Zhao Yu's betrayal puts Chen Feng into a desperate situation, and the mission of guarding the artifact and preventing disaster has been on his shoulders since then. This ancient tomb exploration eventually became a life and death battle concerning the survival of the world.
