Mu Xi was born in the world of immortality, and was born with the best thunder spirit root that could only be found in ten thousand years. However, because of the crime of having a jade, he and his parents fled to the world when he was young. After joining the Sword-seeking Sect, she discovered that her spiritual roots were related to the inheritance of the ancient Thunder God. What was even weirder was that she always saw a girl with a similar appearance to herself in her dreams - Lin Qingyue, the legitimate daughter of the Lin family in Yong'an Continent. The purple lines on her forehead resonated with the thunder in her Dantian.
During an adventure in a secret realm, Mu Xi accidentally encountered an ancient chess game, and the twin sisters finally met. Only then did they realize that they were twin weapon spirits transformed from the Thunder God's sword. One of them could control the power of thunder and punishment, and the other could deduce the secrets of heaven. And the truth that no one has ascended in the past five thousand years is that the demon has devoured the world, and the path to immortality has been cut off!
The Piaomiao Sect secretly colludes with the demons in order to use the chaotic spirit body as a sacrifice to open the passage to the demon world; the parents are the reincarnations of the guardians of the Thunder Temple, and they have planned for thousands of years with their lives; the reverse scale of the blue dragon hidden in the heart of the master is hiding the last glimmer of hope...
When the blood-colored moon rises, Mu Xi and Lin Qingyue join forces with their swords, and the thunder calamity from the sky splits the sky——
"Who said that the path to immortality is over? Today, my sisters will re-build the ladder to heaven with the Thunder God's lineage!"
