I Became a Mafia in the Academy - Chapter 16

Caelen died doing what he loved most: playing survival games non-stop like a sleep-deprived goblin. Unfortunately, dying in your chair from gaming overload isn’t exactly what you’d call a dignified exit. Even God laughed at him.But lucky for Caelen, or maybe unlucky, he gets a second chance in the world of his favorite survival game. It’s a brutal fantasy realm full of monsters, magic, swords… and absolutely zero indoor plumbing.Armed with only a stone pickaxe, a limited-use “Google Brain” search skill, and the stubbornness of a man who once built a Minecraft mansion out of dirt, Caelen sets out to survive. But surviving isn’t enough he wants to upgrade the world. Electricity? Toilets? Toasted bread? Why not all three?As he fends off nighttime horrors, awkwardly crafts furniture, and tries to avoid becoming monster chow, Caelen has one mission: bring modern convenience to a medieval world, one ridiculous invention at a time.And maybe, just maybe… not die again in a chair.[System Notes:No Ntr, No Yuri(gl), No Yaoi(bl)]

I spent my life playing a game.
I hit the wall, stuck in second place for the rest of my life.

Out of the blue, I received a message and was possessed by the game.
As the worthless son of an Underworld Boss!

“Yes, bloodline is also a power, as long as you can use it. My ability is ‘Famiglia’.”

The game addict never disappears. Overwhelming violence, endless wealth, connections in the other world. I, I’ll use anything to stay alive!
