Bu Chenge, as a descendant of the Sword Immortal, once blocked the catastrophe of the demon world with one sword, but due to romantic debts and power struggles, he was deprived of his immortal status, cast down from the mortal world, and became a vagabond that everyone can bully.
The modern girl Tang Xin's soul traveled into this fairy tale drama and became an invisible "ghost" around him. Without entity and unable to be touched, she could only silently accompany the frustrated hero and witness his suffering.
Bu Chenge was bewitched by the vicious female Mo Yu and fell in love with Fanxing, a scheming female disciple of the sect. However, he was scorned and exploited in exchange for his heart and soul. Tang Xin was heartbroken, but without Bu Chenge knowing it, she shared part of the heart-gnawing pain for him. At the critical moment, he sacrificed his chance to block a fatal blow for Bu Chenge.
The old swordsman brought Bu Chenge to the ancient temple to practice hard and sharpen his sword. The girl's soul met Wanlian, a psychic who could sense her, and the two became confidants spanning life and death.
When the psychic's life came to an end, she gave her body to this helpless soul and borrowed it to resurrect her soul. Finally, she was no longer a bystander in nothingness, and reunited with Bu Chenge. Their past stories and various mysteries were finally explained.
Mo Yu discovered that he actually loved Bu Chenge deeply, and he also blocked the devil's attack for Bu Chenge. At this point, Bu Chenge fully awakened and began to face up to his responsibilities and save the fairy world again.
Intention: True love is selfless, I just hope that everything will be fine for him/her
