Modern young man Xiao Yichen died unexpectedly, and his soul traveled through time and became an outer disciple of the Shushan Sword Sect. When he first entered Shushan, he seemed to be enveloped in a haze, and was ostracized and bullied everywhere. The outer sect senior brother Murong Yuntao relied on his position to be arrogant and arrogant, and united with the inner sect disciples to suppress Xiao Yichen in every possible way, treating him as a thorn in his side. But in this darkness, the kind and gentle junior sister Chu Lingxi reached out to him, giving him warmth and encouragement, and the two secretly fell in love while supporting each other.
A sudden turn of events occurred. By chance, Xiao Yichen activated the Heaven-defying System, thus starting a counterattack. He practiced hard day and night, using the system to rapidly improve his strength. He gradually grew from a low-level disciple of the outer sect, who was despised by others, to a core figure in the inner sect of Shushan, with a sky-high reputation. People who once laughed at him can only look up at his back.
However, Murong Yuntao was unwilling to fail and colluded with evil forces to carry out crazy revenge. Xiao Yichen had to fight to the death against the evil forces in order to protect the people he loved and everything he cherished. In this battle, his friendship and love are facing huge tests. When strength and friendship, glory and sacrifice are placed in front of him, how should Xiao Yichen choose? Can he protect the justice in his heart and write his own legend of Shushan?
