Undying Healer: OP MC Regression Litrpg Apocalypse

The Greatest Healer in human history dies to the spear of an ancient race.That is how his life ends—defeated by the hands of someone who should be his equal in levels, yet stands so far above him in power and scale. He and his entire party are crushed by a single figure from an ancient race that treats human magic like an untimely joke.John refuses that ending.He rises from a deep sleep, regressed to the beginning of it all, mere moments before the System initializes, armed with a decade of hard-earned knowledge and one opportunity to rewrite everything. He knows where the best loot is, where the biggest wars start, who the most evil people are that hide among the masses, which paths to take to unlock the best skills, and which paths forge the monsters needed to survive what he knows is coming.He knows which floors and dungeons to avoid like the plague and exactly how fast their destruction comes when humanity wastes time playing politics and arguing over scraps instead of growing more powerful.This time, John doesn't just cast healing and support buffs from the backline.He takes a path none thought possible, an Undying Healer, forcing the world to contend with a front-liner who is also the greatest healer humanity has ever known. He must learn to fight in the mud, on the wall, blade and spear in hand, face to face with the monsters he has avoided for so long, all the while casting mighty healing spells through a tier-locked System that insists he shouldn't be able to.The System doesn't care if humanity is wiped out.Ancient races plot and plan to destroy them.Beings of immense power want humanity as nothing more than free experience.John refuses to make them any of those things.
