Final boss 0: A Dungeon Core LitRPG

Death, then life. Then a shithole. A shithole called a dungeon. Yeah, imagine dying, then being dumped in the bottom of a cave and given control of a bunch of poisonous stuff. Zero, a level 1 gray dragon, and the final boss of the dungeon he was put into has to make the most of his abilities. He also came to learn that the people of this world's morals are not the same as his original. At least, he thinks they're different. Murder, backstabbing, and all forms of treachery are seen as merely a part of daily life. Zero won't have that. His human side and his dungeon side constantly battle, seeking growth in different ways, through slaughter or through kindness. But he'll be fighting an uphill battle. He will need allies, friends, and power.  He will need to be the strongest if he wants to fix the world. Ride along with Zero as he learns to deal with his own deteriorating emotions and murder-hobo instincts, all while trying to cozy up with a hot elf-dryad(not literally, don't expect romance). What to expect: -Main character becomes a dragon with a Game-like system(as is the trend among gods apparently)  -Main character with fractured memories constantly fighting the natural instincts of the apex predator that is the Core Guardian of a dungeon -A first-person perspective following an intelligent and analytical MC that doesn't want to kill but has to -An MC that isn't some calm badass most of the time. In fact, he's usually quite afraid to die or lose those he cares about. Sounds like a sensible guy. -A unique magic affinity and system that he shares with those who are a part of his dungeon. -Found(or technically spawned) family -Characters wondering just how genuine their emotions are as the influence of the dungeon core fills their minds. -a Fairy Empress opens a restaurant chain -Red -This is not a harem.
