Reborn in the Three Kingdoms: I Found Hua Mulan in My Tent from the Start

I woke up one day, and found myself the expendable commander defending Hulao Pass. Before me was Guan Yu’s Green Dragon Crescent Blade, behind me was my fleeing superior, and under my command was a band of terrified old, weak, sick, and injured soldiers.

Just as the allied cavalry charged and the defenders lost hope, three thousand light horsemen evolved into the Great Tang’s Black Armored Army! From then on, Chen Changsheng’s life took a wildly different turn. A maid who fainted from fright evolved into Hua Mulan; foot soldiers on the verge of death evolved into the Yue Family Army; a spear technique he jotted down on a whim evolved into a god-tier martial art... When a million Hu and Qiang warriors laid siege to the pass, I, Chen Changsheng, stood at the front: In this life, I will! Restore the Han Dynasty!
