Signed In for a Hundred Thousand Years in the Lower Realm, Invincible Upon Ascension!

Lu Ran spent one hundred thousand years atop Kunlun Peak, waiting for the chance to ascend. After successfully enduring the nine bolts of tribulation lightning he ascends but arrives in the Spirit Realm instead of the Immortal Realm. He appears in an Immortal Washing Pool where he meets Mu Yunzong and his party from the Great Luo Sword Sect who are retrieving their young lady Mu Yao through a bloodline tracing method. Lu Ran helps by carrying Mu Yao out of the pool during which he inadvertently touches her. Mu Yunzong explains that ascenders from the Lower Realm are sent to the Spirit Realm where spiritual energy is used for cultivation and his own vast qi reserves are converting rapidly improving his realm.

Lu Ran has a system that allows daily sign-ins. His first sign-in in the Spirit Realm grants him the Chi Dragon Armor a spirit treasure and substantial spiritual energy quickly boosting his realm to the sixth heaven of True Immortal. He joins the Great Luo Sword Sect as a guest elder due to his True Immortal status. The sect master Su Yueling is revealed to be his former disciple from the Lower Realm who learned the Primordial Purple Sword Art from him. The art was created by Lu Ran himself to tease her. Su Yueling has established the Great Luo Sword Sect with her sisters and is actively searching for Lu Ran having seen the Ascension Ranking and deployed disciples to all Immortal Washing Pools within her territory.

Lu Ran chooses to hide his identity using the alias Ye Nan to create a surprise for Su Yueling. He meets Su Mei the Great Elder who arranges for him to stay in a cottage by a cliff. He explores the sect and sees the Heaven Measuring Ruler a divine weapon he gave to Su Yueling which is now treated with great reverence. Su Yueling is distressed at not finding Lu Ran but Lu Ran remains incognito believing they will meet eventually. The main conflict involves Lu Ran navigating the spirit realm while keeping his identity secret. He learns about the spirit realm including the fact that natives cultivate without tribulations and that ascenders start from True Immortal realm.

Lu Ran adjusts to the spirit realm enjoying the benefits of his system which continues to provide cultivation rewards. His realm advances steadily as his accumulated qi converts to spiritual energy. He observes the sect operations and notes that Su Yueling is worried about his safety. Despite the temptation to reveal himself Lu Ran waits for the right moment planning a grand reunion. The story highlights his ease in the spirit realm and his confidence in his abilities derived from his hundred thousand years of cultivation and the system rewards. It sets the stage for future events where Lu Ran will reveal himself to Su Yueling and potentially reunite with his other disciples as he continues his journey in the spirit realm.
