The Apocalypse tribe who lived in seclusion lost the secret book of firearm mechanism. In order to obtain the power of red gold stone, Yuan Xingguang, nicknamed Sirius, attempted to change the past and took the stolen secret book to open any door of the Apocalypse tribe and fled.
During the Shengtai period of the Xia Kingdom, the five kingdoms stood in a powerful position, and they fought for years. The world was in chaos and was not unified. The appearance of Sirius carrying firearms and mechanisms has intensified the disputes between countries, and the war has intensified.
In order to prevent all life from being ruined, Chen Ming, the patriarch of the Apocalypse tribe, sent Chen Yurou, the successor of the cracking mechanism, and guardian Liu Jianjun (Zhu Ye) to recover the stolen secret book and get rid of Sirius.
Faced with Tianlang's identity as Prince Duolun of Juchi, Yurou and Zhuye, who have no identity background, decided to join Tianlang's enemy country, Xia Kingdom, and help them fight against Juchi's firearms agency. However, Mu Tianxi (the seventh son), the governor of the Xia Kingdom, did not trust them. Amid constant conflicts and temptations, a new partnership was established. At the same time, Yurou and Jianjun were also unknowingly involved in the undercurrent of the Xia Kingdom's imperial power struggle and could not escape. Mu Tianxi, the iron-blooded warlord with a cold, arrogant and murderous personality, has a cold and cute charm, while Mu Tianyou, the gentle and harmless Prince of Qing, has a dangerous edge. In this chaotic world where heroes are vying for the throne, can Yurou and Jianjun successfully complete their mission and stick to their pursuit?
Mu Tianyou's journey to fight back, seize power, and conquer the world unfolds as the main line.
Chen Yurou's master's family was massacred, and after falling off a cliff and losing his memory, he was rescued by the mysterious Phoenix City Lord Feng Feiqing, and lived with his master Hua Yuan in Changlin, the fief of King Langyue of Gaozhan for a year. In an unexpected competition, Master Yurou (Hua Yuan) entered the palace where King Langyue was selected as an official.
