In the twenty-sixth year of the Republic of China, a strange mummy was found at the Black Fengkou of Yinshan Mountain. He was holding a bronze plaque with a three-legged bird in his arms. The bloody words in the suicide note were shocking: "When the mysterious coffin is opened, thousands of corpses will be born - I should not open the coffin!"
Sixty years later, Chen Jiu, an antique dealer from Panjiayuan, received this bronze medal. Grandpa's expression changed when he saw it, and he revealed the truth that he had concealed back then: that night, he saw the mummy open its eyes with his own eyes.
From then on, Chen Jiu was involved in a fate that spanned a thousand years. He was born with yin and yang eyes, and he assembled the taciturn Zhang Tan, the foul-mouthed and reliable Fatty Wang, and the master of archeology Shen Nian to form an expedition team. From the "Bronze Eyes" under the faceless murals of Yinshan Mountain to the city of the underworld demon in Kunlun's Death Valley, they approached step by step the legendary Kunlun Ruins - nine hundred-foot-long bronze dragons dragging a black sarcophagus with chains: the Nine Nether Dragon Coffin.
The coffin is engraved with star charts, and the dragon's body is densely covered with names: coffin keepers from past dynasties. Chen Jiu found his grandfather and his father who disappeared eighteen years ago.
The nine dragon talismans opened the dragon coffin. What was in the coffin was not bones, but a staircase leading to the center of the earth. Deep in the center of the earth, an ancient city hangs upside down, which holds the secrets of the earth's civilization's many destructions and rebirths.
The even more shocking truth is: Zhang Tan was actually a reincarnation of the previous civilization era; his father's "death" was a wait spanning eighteen years; and Chen Jiu's yin and yang eyes are the key to unlocking the seeds of civilization.
If it is opened, modern civilization may be overturned; if it is not opened, the truth will always be buried in the abyss.
Who is buried in the Nine Nether Dragon Coffin? Only when a thousand-year fate weighed on his shoulders did he realize that there were some secrets heavier than death.
