When the Qin Dynasty unified the six kingdoms, Xu Fu, an alchemist from the East China Sea, presented Penglai Xuanjia Jade Slips to reveal ancient secrets. The golden patterns on the dragon robe of Qin Shihuang Ying Zheng, the bronze eagle head armor of Meng Tian in the north, and the heirloom jade pendant of Meng Yi all resonate with Xuan Jia.
The bronze plates under the Epang Palace, the bronze doors in the Lishan Mine, and the Xuanjia Well in the King's Court of the Huns all contain clues to the "Seven Weapons of Xuanjia". Li Si discovers the secret of the Xuanjia cage recorded in "Book of Zhou", Zhao Gao secretly practices the secret technique of Xuanjia soul-changing, Zhang Han encounters the alienation of corpse air armor, and various forces start a game around Xuanjia.
When Meng Yi takes the jade pendant to the north to rescue Meng Tian, the prophecy of the resonance of the seven weapons gradually appears. Is this a sacred object that governs the country, or is it a monster that devours the world? A battle for the mysterious armor, which was related to the lifeblood of the Qin Dynasty, officially kicked off with the bells of Xianyang Palace.
