Reset World Line

Yang Si is a detective, but he is only obsessed with an old case nine years ago. Because the target of that serial murder case was originally to kill himself, but because of the ability he once had, he could not succeed, so the target became his relatives and friends, and then he left the island where he lost everything. Due to various reasons, he returned to this island again, and due to "a coincidence", he returned to nine years ago - before the murder occurred. He tried to find the missing murderer, but found that there seemed to be another person coming back to the present from the future, and that person was also acting secretly, and seemed to be very close... After solving these problems, Yang Si ushered in a long vacation, but during the wonderful vacation, he picked up a strange-looking doll... After everything was over, Yang Si became a detective again, but he was no longer obsessed with a certain case. But after he thought the dust had settled, a man who called himself "Crack" came to him.
