Traveling through the Republic of China in 1925, Lu Chenzhou became the lowest-level coolie at Jinmen Wharf.
Warlords fight in confusion, foreign powers run rampant, and human lives are like a piece of grass.
Until he accidentally opened the underground dragon vein arsenal - the military heritage of the Ming Dynasty three hundred years ago.
"Imitation Mauser? Too backward."
"The Japanese have tanks? I have a machine gun position."
"A blockade by foreign powers? I am self-sufficient."
From underground arsenal to heavy industry empire, from dock coolie to uncrowned king.
Lu Chenzhou said: "What this era needs is not warlords, but the power to keep everyone fed and straight."
And all this started when he built the first "Jinmen Made" under the eyes of the warlord.
