From A Stronghold NPC To The Final BOSS - Chapter 1028 - : Here they come

Demons in Academy of Light are described as vile, dark, cruel, evil, impure, and a whole lot of other things. At least, that’s how they’re portrayed in the game—a sacred land where demons and dark energies aren’t supposed to exist. That’s how it was supposed to be... So what the hell am I supposed to do now? Thanks to my rotten luck, my soul ended up possessing the lowest-ranking demon, the one who dies at the very beginning of the story... I’m screwed! I have no other options left... If I want to survive, I have to kill the protagonist.

Demon Lord! A symbol of terror and evil! Killing and death are associated with him! In a magic country, a being was summoned. This being was the most demon lord unlike of all demon lords in history.

“Your majesty demon lord, please sign a document here. But please be careful not to put your hand at the wrong place.”

“Your majesty Ya Lin, human army are invading us but I will protect you with my life!”

“Hate you! Don’t come closer! You are a real pervert demon! I hate such demon the most!”

O God, what is this? I just wish to be an ordinary person with carefree life and stuffed with food till death. Why I am the one who will become the future husband of the demon princess, the future demon lord? And also completing a near impossible task ——-resurrecting my mother-in-law? Luckily becoming a demon does have its own benefits, granting each demon ability to cultivate skills.

However, what type of circumstances are this, mission going to other worlds and conquer them?
