"Fengyun Bian" tells the story of top martial artists Bu Jingyun and Nie Feng, who, with the help of unknown seniors and mysterious outsiders, transform into a quantum state in response to a catastrophe that is about to sweep the entire human world. Their whereabouts are unknown. Three thousand years later, an asteroid collided with Earth, turning the surface into a barren wasteland. Trapped underground, humans gradually discovered the existence of a superpower called "pulse energy" within the human body. Orphan Bu Tianyun from Dungeon 32 unexpectedly awakened Bu Jingyun, who was sleeping in the meteorite. From then on, he discovered the potential of his own "pulse energy" and, together with Nie Zifeng, the descendant of Nie Feng, embarked on the journey of becoming a "pulse energy warrior", fighting to protect the world.
