Tree of Aeons
spaizzzer
Matt is reincarnated as the most unlikely of heroes - a tree - in a fantasy world that serves as the battlefield for an ongoing conflict between demons and heroes summoned to oppose them. As TreeTree, Matt is not just any tree but an overpowered one who learns skills, gains levels and wisdom, builds a forest, guides young heroes, protects a village and eventually expands into an empire spanning multiple worlds. With nearly 15 million views between Royal Road and ScribbleHub, the epic reincarnation/isekai LitRPG spans centuries as Aeon grows from sapling to world-spanning entity defending against relentless demonic incursion, recruiting allies, building institutions and taking the fight to demon-controlled realms.
Progression: Explicit LitRPG progression is central, quantified and foregrounded every volume. Protagonist Matt/Aeon gains Levels, Skills and evolutionary upgrades as a tree; progression is measured via level-ups, skill acquisition (e.g., forest manipulation, magical abilities), wisdom stats, root/territory expansion, and empire-building tiers. Human allies and heroes also level via Classes and Skills. Each book structures arcs around power accumulation - amassing power, training forces, crafting equipment, amassing allies, and navigating relationships with heroes - while facing escalating demonic tiers and inter-world threats. Levels directly gate survival against demons, kingdom-scale politics, and void-sea exploration. Descriptions per volume emphasize 'gain levels and wisdom,' 'amass more power, train his forces, make more equipment,' 'accumulate more power, and build up their war potential,' and 'push back' against demon worlds, making structured advancement the engine of plot, combat and worldbuilding across 8 volumes (2023-2026).
