Lin Feng, a modern young man, accidentally traveled to the ancient world where martial arts flourished, and was caught in the whirlpool of troubled times. From being ignorant and seeking survival to realizing the sword and opening up the meridians, he relies on modern wisdom and extraordinary understanding to grow up in the conflict between good and evil. Involved in sect grievances and border wars, he also forged a romantic relationship with a cold fairy and a charming witch. Until the demon king came to the world and the people were hanging upside down, he finally discovered the truth of martial arts in the blood and fire, and used the blue sky sword song to decisively fight at the top of heaven. This is a chivalrous pursuit that spans time and space, and it is also an epic story of finding a way back between loving and hating the common people.
