The Sword Presses the Sky: Senior Sister and I Are Inseparable

This is a vast fairy world where "sword" is respected and full of spiritual energy - the Jiuxiao Linghuan Realm, where there are many sects in heaven and earth, and immortals and demons coexist. Practitioners absorb the spiritual energy of heaven and earth, temper themselves, and pursue the ultimate in swordsmanship. The ultimate goal is to break through the nine heavens, ascend to immortality, and gain immortality and supreme power. The world is vast and vast, divided into the land of Kyushu, the four seas, and the "Nine Heavens Domain" suspended in the sky with the richest aura. Legend has it that there is a mysterious gate to the fairy world above the Nine Heavens. The male protagonist Xu Kai and the female protagonist Mo Xiaozhu in this book come from the Tianyan Sword Sect, the leader of Kyushu's righteous path. On the surface, Xu Kai and his senior sister are competitors. For some reasons, they "give people the feeling of being irreconcilable." In the end, they depended on each other through life and death, separated from the clouds, and stayed together for a lifetime. This is my first time writing a book, so I didn't write it well. Please forgive me, readers. My senior sister and I are at odds with each other (that's weird)
