The Huang in Yanhuang

There were disputes among the feudal princes and factions inside, and the lords were eyeing him outside. Let's see how the protagonist turns the tide, rewrites history, annexes various vassal states, and builds a unified Chinese empire in Asia. The protagonist is directly transformed into a young Wuhou.
