In the 20th year of Guangxu's reign, on the eve of the Sino-Japanese War of Sino-Japanese War. Lu Yu, a 16-year-old boy who was sold into the Beiyang Navy by his stepmother, touched a rusty "Shenwei General" iron cannon while carrying artillery shells at the Weihai Guard Port, and accidentally activated the "Yuci War Armor System" - a Ming and Qing war strategy system from another time and space. It can obtain the armor fragments of famous Ming and Qing generals by absorbing "historical fragments". Each time a set of armor is collected, a famous historical general can be summoned to possess him and fight.
However, this system has a fatal flaw: each use consumes the host's "health points", and over-reliance will accelerate death. What's even more fatal is that Lu Yu discovered that there was a secret order from "Emperor Tianqi" hidden in the system - he must find and eliminate a "traitor who stole the dragon's veins" within three years, otherwise the entire system would self-destruct and he would be wiped out with him.
Just as Lu Yu was gradually making a name for himself using the armor, a "yandere" commander whose identity was a mystery - Ying Jun (an army major general who had returned from studying abroad in England) approached him on his own initiative, sweet-talking, giving careful guidance, and even taking bullets for him. Lu Yu regarded him as his brother, and the two fought side by side, from Pyongyang to the Yellow Sea, and from Dalian Bay to Liugong Island.
But the British monarch's true identity is the descendant of the "traitor". She approached Lu Yu in order to steal control of the imperial armor and resurrect the corrupt dynasty in the late Qing Dynasty. When Lu Yu finally discovered the truth, he was already trapped in the whirlpool of trust and betrayal, and the person he trusted the most became his most deadly enemy.
The ultimate game on the battlefield of Sino-Japanese War, a life-and-death battle of trust and betrayal, begins here.
