Sect Saved By One Sword Against Four Demon Kings

Ye Li, a transmigrator, joins the Kunlun Sword Sect but is reduced to a handyman. In despair, he awakens a Check-in System. Over a hundred years, he checks in at various locations to cultivate, breaking through from the Qi Refining stage all the way to the Dragon Transformation Realm. When the Four Great Demon Kings besiege the mountain, he slays all four with a single sword strike, saving the sect from collapse. After marrying the sect leader’s daughter Dantai Ruyue, he descends the mountain with his Yuanhong Sword to gather the nine immortal swords, uncovering the truth of the Nine Provinces and the Heavenly Evolution Sacred Land.
