Lan Chang’an has gone through two lifetimes of reincarnations, and in the third life, he aimed for stability until reaching the Nascent Soul Realm in hopes of unraveling the mysteries of the Nine Seal Stele. Consequently, he cultivated the Ancient Trees Evergreen Technique, which wielded modest power in return for greater lifespan.

His approach is not one of fearlessly engaging in battles, but of navigating with steady precision and forging meaningful bonds with others.

Throughout his long cultivation journey, he encountered individuals at various stages of their cultivation, including a Decent Faction Head, a Prodigious Beauty, a Giant Demon Lord, an Evil Cultivator, a Thousand-Year Old Demon, and a Puppet Master Pulling Strings From Behind The Scene.

Observing the ebb and flow of the world, witnessing its ups and downs, he unknowingly became a living fossil in the realm of cultivation, akin to an evergreen tree spanning through eternity.
