Transmigrator Ye Li joins the Kunlun Sword Sect only to be reduced to a handyman. In the depth of despair, he awakens the check-in system. Over a hundred years, he checks in and cultivates everywhere, breaking through all the way from Qi Refining to the Transforming Dragon Realm. When the Four Demonic Kings attack the mountain, he kills all four demons with a single sword, saving the falling sword sect. After marrying Tantai Ruyue, the headmaster's daughter, he descends the mountain with the Yuanhong Sword to gather nine immortal swords, exploring the truth of the Nine Provinces and the Tianyan Sacred Ground.
