I Quit the Party, but the Elf Innkeeper Invited Me to Stay the Night?!

【Kicked from the Party and Making a Comeback + Western Fantasy Dungeon + Stronger the More Damage He Takes + Multiple Heroines + No-Frustration Power Fantasy】 After raising my teammates for three years, they turned around and joined the Hero, kicked me out of the party, and called me useless. “You can’t give us what we want, so what right do you have to hold us back from a better future?” They used me and tossed me aside. Three years of effort became a joke. Heartbroken, I got drunk at a tavern. As the place was closing late that night, the elven proprietress gently shut the door. No one knew I bore the Demon King’s curse and had awakened 【Desperate Death Aura】: For 2.5 seconds after being hit, I’m absolutely invincible, and every bit of damage I take is reflected back at double strength! I stood firm against a dragon’s breath, cleared the depths of a dungeon solo, and charged straight through the sixth floor where the Hero was stuck, unable to make any progress. A gentle elven proprietress, a dashing princess-knight, a cold-blooded assassin… They joined me on my journey as I fought my way back to the top. Those who once trampled on me will sooner or later kneel before me and beg for forgiveness. No frustrating plot twists or angst, and the protagonist is straightforward and never abandons the story. Read without worry, dear readers.
