Zhou Yuan transmigrates into a gamified fantasy world where everything has a visible health bar, and he is the only player in existence. His skills are not granted by a system; instead, he unlocks them through repeated hands-on practice. Starting as a lowly young man from Qiaoxi Village, he grows stronger by practicing sword techniques and repeatedly clearing dungeons, eventually joining the Jing'an Army and encountering deadly battles in secret realms. A sinister conspiracy involving the Painted-Skin Ghost Mother erupts in Jing'an City, where ghostly creatures disguise themselves as ordinary officials and civilians. Using his ability to see through health bars, Zhou Yuan repeatedly overcomes crises, navigates conflicts between various factions, and fights against the Painted-Skin forces infiltrating the entire city. At the end of Season One, he and a Jing'an military officer fall into the Painted-Skin Yin Ghost Cave dungeon, where a sudden crisis leaves viewers with a huge cliffhanger.
