Wu Aiguo was once the most secretive Thousand-faced Thief King. Before his death, his master left a clue: the Nine Dragon Key around Zhang Siyang's neck was just one of the nine Dragon Keys scattered in the war. He took Tang Liang and teamed up with Zhang Siyang to cross the jungles of the Northeast, the Gobi Desert in the West and the shipwrecks in the South China Sea. The nine keys finally gathered together - what was opened was not a mountain of gold and silver, but a volume of history that had been deliberately erased and a name that should have died. At the end of the thief's path, he stopped in front of the truth: what Xiao Wu wanted to steal was no longer money, but the answer and his own roots.
