Three hundred years ago, the leader of the Immortal Sect, the "Tianyan Sect", was destroyed overnight. The whereabouts of the sect's most precious treasure, the "Tianyan Dao Canon", were left unknown, leaving only a prophecy that "when the Dao Canon comes out, the Dao of Heaven will be overthrown". From then on, the path to immortality in Kyushu was cut off. Three hundred years later, Xie Lingshu, an orphan carrying the blood of the Tianyan Sect, embarked on a journey that no one dared to take as a mortal. She does not seek immortality, nor does she admire immortality. She only wants to explore the truth behind the sect's destruction and seek justice for the thousands of innocent souls who died in vain. When she pushed open the fairy door that had been dusty for three hundred years as a mortal, she discovered that the so-called "immortal" was just a false god who stole the fate of heaven and earth; the so-called "heavenly way" was nothing but a carefully woven lie. Facing the long-decayed fairy world and the eyeing old gods, she could only use the sword in her hand to open a path to the sky for mortals. If there is no justice in these three thousand floating worlds, I will be fair!
