I Am the Second-in-Command of Blackwind Stronghold

[Reborn as a villain in a game + endlessly stacking buffs + building a faction and conquering the world] Qi Jinshu is reborn at the game's launch and becomes the second-in-command of Black Wind Stronghold. With waves of players bearing down on him, he has to find a way to defend the stronghold. Otherwise, he'll lose his self-awareness and become a fixed NPC in the dungeon.
