Season 1: A spacetime experiment goes out of control, and scientist Lin Dao leads a team to crash into the Kunlun Immortal Realm. The immortal sects view them as demons, quantum guns are no match for Qingxiao swords, and in a desperate situation, the only way to survive is back-to-back with the cold and elegant female cultivator Shen Li. Former mentor Lu Chen secretly seizes the spacetime core, attempting to merge technology and immortal power to become a god, pushing the two realms to the brink of collapse. Lin Dao uses technology to break immortal arts, and Shen Li uses sword Qi to suppress the rifts. Going from mortal enemies to fighting shoulder to shoulder, an immortal-technological resonance seals Lu Chen with a single strike. However, the rifts are not yet calm, and the path home has not begun—an even larger otherworldly realm is opening its eyes deep within the cracks.
