When Lin tide, a top psychiatrist, took over Chen Xiao, the archaeological team leader who claimed to be "cursed by a dragon," she thought it was just a tricky trauma treatment. Through hypnosis and dialogue, she guided him deep into the memory of the Han Dynasty royal tomb that swallowed up his teammates. The murals of the underground palace began to appear in her dreams, and ancient mechanisms and curses gradually eroded reality. In order to completely end their nightmare, Lin tide, a theoretical person who has never been to the ground, had to follow the recovering "Golden Captain" Chen Xiao and take the initiative to step into the treacherous underground world. This time, what they stole was not the underworld weapon, but the truth hidden deep in the fog of history, and the only light of redemption that can illuminate the darkness deep in each other's souls.
