Towerbound (LITRPG + REGRESSOR + OPMC)

They left him for dead. Now he’s back—and he’s bringing the tower down. Ren Varrow was never meant to be a hero. A quiet healer and alchemist, he preferred crafting potions over charging into battle. But when a top guild tricked him into a deadly dungeon and betrayed him, Ren’s story should have ended. Instead, it began again. Thrown back in time before the Tower’s first rise, Ren now knows what’s coming: the betrayals, the hidden quests, and the secret that could doom Earth itself. Armed with future knowledge and forgotten skills, he’s ready to rewrite everything. He’ll build a guild from nothing, craft legendary potions, and climb through monsters, traitors, and a hundred deadly floors. Because when the real Tower erupts across Earth—and the countdown to destruction begins—Ren won’t be left behind again. Alchemy. Betrayal. Revenge. The climb starts now.
