After Su Ran came back from the mountain for training, the Qingyun Sect had already changed. Lin Zhirou, the junior sister she had protected for ten years, was killed by her master's new disciple Du Qiyan, and was also slandered by the entire sect. A former classmate turned against him and his master favored him. Su Ran gathered all her tenderness and took up her sword to take revenge. Even though Du Qiyan is the destined heroine protected by heaven, she still has to go against her destiny, overcome the calamity, put down the hypocrisy, imprison the evildoers, collect blood debts, and guard her junior sister's golden elixir until she returns.
