Shen Yue accidentally obtained a bronze key that could travel through nine broken alien spaces, but he did not know that each space imprisoned ancient witchcraft that destroyed the world. Now that the key seal is loose, the nine guardians of witchcraft detect and stop Shen Yue. He must learn to control these powers before the space collapses. Shen Yue was emotionally indifferent in the early days and had many obstacles when cooperating with his helpers. He also encountered interference from swingers due to misunderstandings. If the mission fails, the real world will be torn apart, and his own life will not be saved. In this tense countdown, Shen Yue relies on the system and races against time, trying to master the forbidden power and change his destiny.
