Dungeon Instances Descend Across the Heavens? From the Start, I Move into Sweet Home

[Mostly Set in the World of Korean Dramas Early On, with Other Worlds Added Along the Way, Including Horror and Thriller Game Worlds] Qi Ran transmigrates into the body of a medical student and discovers that this Blue Star is crawling with monsters... Monsters born of desire, zombies, parasitic beasts... and all sorts of demons and freaks! This world also contains something supernatural: The Myriad Worlds Dungeon! Those monsters are what appear in reality when people fail to clear the dungeons. People believe this is punishment from the will of the world... Everyone has to struggle to survive, and they’re also forcibly dragged into dungeon worlds... Get stronger and live, or die! But Qi Ran isn’t afraid at all. He’s thrilled! Because he’s discovered that these dungeon worlds are all based on movies and TV shows he watched in his previous life! And the crucial thing is, he’s the only one who knows the plots! So Qi Ran starts pulling all sorts of crazy stunts. In the eyes of everyone else, even the dungeon NPCs, his actions are enough to make their scalps crawl! "Sweet Home": Take advantage of a newcomer bug to perform live dissection experiments on a hungry monster! "The Gorge": His teammates just want to coast through the dungeon, but he drags them into it and releases hollow men into the open, spreading them across the entire United States! "All of Us Are Dead": The cool, aloof class monitor wants to cuddle, but he’s thinking about killing her! "Train to Busan": Everyone else is desperately running for their lives, but he insists on injecting zombies with a half-zombie serum, fighting poison with poison! "Moving": While everyone else is figuring out how to win over the NPCs, he spreads a zombie virus! "The Shop of the Lamp": Everyone is scared out of their wits, but he does the opposite, vowing to study the yin-yang arts with ghosts and monsters... "Duty After School": He ignores the passionate advances of all the beautiful girls and walks toward the tentacle monster with a smile!
