In the twenty-sixth year of the Republic of China, war broke out, and the undercurrent of the Shanghai Concession was raging.
Chen Jiuhuai, a young boy from the countryside, fled with a mysterious copper box in his arms. However, he came across an object that was exactly the same as the box in his arms at a drug store. He was even shocked to hear that his mother was arrested by the Japanese army for "privately hiding the copper box". Lin Xiuyuan, the owner of the medicine shop, broke off his finger and hid a secret. Su Manshu, a cheongsam tailor, broke the situation with a gun and involved him in a life-and-death game involving the "Nine Cauldrons" secret treasure - it turned out that the copper box in his arms was one of the keys to unlock the legendary ancient Nine Cauldrons.
The ghost of the masked man is still lingering, and the special high school is pressing forward step by step. Many forces are fighting for the key. While on the run, Chen Jiu gradually discovered that his mother's instructions concealed the fate of his family, Lin Xiuyuan's severed finger was marked with a bloody past, and the gun barrel under Su Manshu's cheongsam was not only aimed at the enemy, but also seemed to be aimed at the secrets in his hands.
When the three copper boxes gather together and the shadow of Jiuding casts a shadow over the troubled times, one young man's choice will determine the fate of millions of people. On the edge of a broken country, should we hold on to the keys and survive, or should we use our blood to move history? This secret war wrapped around family affection, betrayal and faith has just begun...
