Keeper of Memory in Two Realms

Dual world criminal investigation + fantasy adventure + growing love The mountain city police received a letter of challenge: It is now 11:26, September 14th. I am leaving, and I will only give you 48 hours to solve the case. If you find me after two days, you will win, otherwise I will win. You can continue to look for me later, anyway, I have already won. The name was signed by Hao Yixun, a 10-year-old criminal investigation fan. The boy disappeared 48 hours later. No one knew that he had entered the Yixu world where "memory can be crystallized". Taking his father's tin box with him, he meets Qing Yuan, an orphan girl who can hear the cry of Yi Ling. The two "weird children" team up to investigate: using criminal investigation notes to see through the lies of the time loop, and relying on the resonance of crystal energy to fight against the darkness that engulfs memories. While the real police are still investigating the disappearance case, Yi Xun has written a new challenge in another world.
