Bog Standard Isekai - Chapter 15Book 4.

While the blue light blossoms, the insignificant struggle at the bottom. He grasps the opportunity to change his fate and embarks on an unprecedented path…

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)]
