Lu Mingfei, become the king of gambling in dungeons!

"Only... Deadpool and the dragon's wail can save Lu Mingfei." "Ten pills for one dungeon run, just a traditionalist like Kazama Ruri." "Stop pressuring me, I'm also... someone who often goes crazy!" The miserable high school student Lu Mingfei frequently enters his dreams of "Dragon Raja," a first-person dungeon survival game where the main character in each dungeon is extremely familiar. At the age when he can least handle pressure, he encounters the most stressful life dungeon. Nights are short, days are long, and from now on, even a king won't study early. This is a reflection of reality, a personal plus-sized rooftop, a dragon-slaying and leveling-up game world more real than StarCraft. Not a rebirth story, purely dragon-themed. Also known as "I, Lu the Grinder, Have to Control Myself," "The Deadpools Lu the God of Gamblers Has Killed in Shilan Are More Than the Hybrids the Camarilla Have Seen," "No Cheating, Who Doesn't Use Evolution Potions in Dungeons?" and "Herzog, I Slew You with a Red Dot Last Time."
