Noble Knight: from Lord to Overlord

In the continent of Adriano, elegance and brutality, redemption and killing, knights and warlocks coexist... The elves have put down their honor and fled to the misty forest, while the dwarves are no longer wild, only stubborn and greedy, hiding in the Tyrsa Flame Mountains! In the mainland, the Kingdom of Indirt proclaimed himself emperor, and he was ambitious and started a war with the intention of dominating the mainland. Rebellion in the Kalman Kingdom has led to wars. What kind of storm will an ordinary Blue Star office worker reborn into this world cause? (The early stage is a wretched transition between war lords, fighting for hegemony, farming, and slow development. I hope you have more patience)
