When the dynasty is overthrown, in the prison of mortal world, his and her swords and the moon will open the first crack in the road to eternal immortality.
In the seventh year of Xuanhe in the Northern Song Dynasty, the mountains and rivers were about to collapse.
Yang Xi, a disciple of the Tiandao Sect and an orphan of the frontier army, was involved in a dispute that transcended the world after his master brought back a broken ancient sword "Gu Yun" from the ancient tomb in Helan Mountain. The sect leader's last words "there are living things in the tomb", the pursuit of the "demon sword" by the powerful in the capital, and the power-seizing and persecution of the senior brother - all crises broke out at the same time on that snowy night.
But when Yang Xi clenched the broken knife and protected his junior sister Dong Yue, who was suffering from cold disease but was willing to die with him, behind him, the ancient knife in his hand suddenly became hot. A blazing torrent rushed into his meridians, and Dong Yue's whole body also condensed with a glimmer of ice crystals - something sleeping deep in the blood of the two people awakened this night.
They don't know that this world called "Mortal World" is actually the "mortal cage" where spiritual energy was exhausted after the ancient war. In the eyes of a warrior, peerless martial arts are nothing more than the most superficial breath transfer in the spiritual world of cultivation. And that "lonely meteor" is actually the key to unlocking the forgotten truth.
In order to solve the mystery of the backlash of Dong Yue's "Xuan Yin Spirit Body" and to explore the truth behind the death of their master, the two followed the clues and embarked on the westward journey to the top of Kunlun. There, what they saw was not a fairyland, but a dilapidated ancient battlefield and an ancient starry sky formation pointing to the "Yunhuang Continent" in the true spiritual world of cultivation.
