In Tianxuan Sect, everyone knows that the shameless sword cultivator brother Jiang Chen's only hobby is to pester his senior sister Bingshan Su Lan - "Senior sister, I have no money to keep my sword, so I'll give you some relief." And the way he exchanged the spirit stone was to sing a hometown tune for her. This was the most vivid bright spot in the sect's daily life, until a huge conspiracy sweeping the three realms surfaced. In order to break the deadlock, to protect the common people, and to protect the person he most wanted to protect in this life, Jiang Chen resolutely sacrificed his body in exchange for a glimmer of life. Many years later, the catastrophe was over, and prosperity returned. However, people can always see the once-cold Fairy Su Lan holding a broken sword on the top of the sea of clouds and repeatedly singing the song that no one can respond to anymore. Everywhere she walked was proof of his existence.
