The protagonist travels back to Shanghai during the Anti-Japanese War, and accidentally accesses a "memory fragment" from a future battlefield recorder in his brain, which can predict the specific military operations and intelligence chain of the Japanese army in the next 193 days. But he couldn't explain the source of the information. Every time he acted, it was like "giving away someone's life." The organization suspected him of setting up a trap, his comrades suspected him of betrayal, and the Japanese army chased him to survive. He must use his "precognition" to fight against the Japanese army while finding a way to prove his innocence in a desperate situation where trust collapses.
