- Description from Novelupdates

Thousands of years ago, the great abilities of the three teachings of Buddhism, Daoism, and Demonism decided on a place for becoming immortal. Three thousand years ago, a Taoist was close to becoming immortal. Three hundred years ago, the Daqian Dynasty was established, and chaos is expected in another three hundred years. In this era, the path to immortality opens; a celestial swordsman freezes fourteen states with one sword, a heavenly Daoist maiden seeks eternal life, a naturally born Holy Son claims to be invincible, and a Buddhist Holy Monk saves all sentient beings.Gu Wen lives as a beggar, enters a household as a servant, witnessing the disordered world, drifting aimlessly.In a world filled with divine beings, he alone is a mortal.However, a lowly origin is not a disgrace; striving through the grand path, even as a common man and mundane son, he can still be the foremost in the world.“Mortal Gu Wen, my Dao is euqaling the heavens!”

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)]
