Years Pass Unnoticed in the Mountains; I Look Back and See an Immortal in the Mortal World

【Invincible + Lighthearted + Travel + No Female Lead + Lan Ke Style】 Xu Guanxuan transmigrates to an unnamed little mountain. He is its only inhabitant, and even time has stopped flowing. His only companion is a volume of Daoist scripture. He descends the mountain and enters the mortal world, wondering how long he has been cultivating. Halfway down the mountain, the Mountain Lord tells him it has been thirty years since he first heard Xu Guanxuan preach. At the foot of the mountain, Peach Maiden tells him that three hundred years of hardship have passed in the mortal realm. Xu Guanxuan travels through the mortal world and demonstrates the Dao, and only then do people realize that an immortal once visited.
