The ultimate class of Golden Time and Space Guava High School welcomes the mysterious transfer student Ling Chen. The ancestral jade pendant that this cold-looking young man carries with him actually hides the key to repairing the rift in time and space. When phenomena such as teleportation of items and memory confusion occur frequently on campus, the KO list masters have not yet noticed that a crisis that can swallow up the entire golden time and space has quietly arrived.
Ling Chen's special power "Space-Time Resonance" can sense the fluctuations of time and space, but because of this, he is involved in the pursuit of the zombies controlled by the black dragon. Wang Dadong's dragon-patterned sword resonates strangely with his time and space emblem, Lei Ting's deadly sweetheart breaks through the limit with the blessing of rift energy, and Gu Zhan's pigs and dogs are not as strong as strong sticks, which reflects the ancient alliance between the Lingchen family and the guardians of time and space. As the rankings on the KO list changed drastically, the conspiracy of the Force Judgment Agency surfaced. Ling Chen had to fight side by side with his partners in the Ultimate Class, fill the broken time and space with the blood of youth, and uncover the ultimate secret of the twelve time and space cycles.
