During the Zhizheng era at the end of the Yuan Dynasty, disasters struck one after another, and tyranny ran rampant.
The Yuan court's cavalry trampled the land. In the chaos, the bones of refugees lay scattered in the open, and the people were plunged into misery.
Liu Zheng, a modern veteran, was struck by lightning and transmigrated to the chaotic end of the Yuan Dynasty, carrying advanced knowledge of military training, combat, infrastructure, disease prevention, and farming to supply the army.
From the start, he joined the weakest rebel army. Its camp was damp and rotting, disease was rampant, discipline had collapsed, petty schemers obstructed him from within, and government troops surrounded them from without. The entire force teetered on the brink of destruction.
In troubled times, people could only fight with blades and cling to life amid mountains of corpses.
But Liu Zheng used modern military methods to defy fate and turn things around:
He dug drainage channels and purified water to prevent disease, eradicating the age-old epidemics plaguing military camps;
He made charcoal, forged armor, and trained refugees, turning them into the first disciplined elite troops of the age;
He used the terrain to set defenses, formations to cut down enemies, and close-quarters combat to deliver killing blows, leading his ragtag, outnumbered troops against the court's regular army!
He rooted out internal traitors, quelled factional strife, and steadied the troops, winning renown with a single battle in the valley;
He broke the encirclement, defeated the Yuan army, took in refugees, and carved out a domain of his own, rising step by step in the south of the mountains.
From a lowly soldier in a ruined camp, to a regional warlord, then to the conqueror of all under heaven.
He swept aside the warlords, drove out the Mongol Yuan, established a capital and founded a nation, rebuilding the Han Dynasty.
With the dynasty established, his ambitions extended beyond the Central Plains!
He launched northern campaigns into the steppes, expanded west into the Western Regions, marched east to Liaodong, and pacified the southern seas,
using the iron might and imperial authority of the Han to awe all nations, ultimately forging an enduring age of prosperity in which the four foreign peoples submitted and all nations paid tribute!
