I Was Liu Yu's Direct Superior from the Start

I transmigrated to the late Eastern Jin dynasty and was ambushed outside Anzhong City from the start. I am a military adjutant, with a thousand elite Northern Army soldiers under my command. One of my low-ranking squad leaders is named Liu Yu. Years from now, he will be Emperor Wu of Song, sweeping all beneath heaven. He will slay enemy generals and save his lord, while I will have his back. The Battle of Fei River has yet to come, and a hidden dragon serves beneath my banner. Watch as I take the reins of the dragon and rise, vie for supremacy in this turbulent age, and bring peace to the realm!
