Three years ago, the unknown secret realm collapsed and 23 students were killed. Chen Zhou was the only survivor.
After waking up, he had a "time trace fragment" in his body - it allowed him to see the reality of the past 5 seconds and predict the danger of the next 0.5 Seconds; but every time he used it, a memory would be permanently devoured.
Three years later, Chen Zhou transformed into an unlicensed warrior in the Demon City, relying on the power of fragments to survive in the underground black market. He had long forgotten what his parents looked like, the name of his first love, and even why he wanted to live.
Until a rainy night, the body of a warrior was discovered. The deceased held a report letter in his hand, and the target of the report was Chen Zhou.
