Transmigrator Lu Chuan was trapped in a small world for one hundred thousand years due to a system error, cultivating peerless swordsmanship yet aging in body. After regaining his freedom, he single-mindedly sought elixirs for rejuvenation. By chance, he met the people of Mingyue Pavilion, stepped in to help when seeing injustice, and successively resolved heavy crises brought by evil cultivators and sects. While searching for the elixir, he simultaneously dealt with hidden disasters across the continent, beginning a hilarious xianxia adventure.
