Ling Yue, the orphan of the Luoxia Sect, dies, and Ling Ye, the interstellar killer, returns. She abandons her weakness to be ruthless, she fights back when provoked, she settles any grudges whenever she sees them, and she makes a name for herself in the world of immortality with her killing skills. Just as the Demon Realm was raising troops, a war between immortals and demons broke out. Due to his military exploits, Ling Ye joined the coalition forces in the Immortal Realm and met Cang Xuan, the cold and alienated Lord of the Immortal Realm. One uses killing to prove the truth, and the other uses order to suppress the world. The two are forced to join forces to fight against the demonic world. From not interfering with each other to relying on each other for life and death, they finally end the war and guard the path to immortality together.
