You Killed My Sister? Then I'll Usher in the Age of the Supernatural!

[Revenge, wish fulfillment, dark, parallel world, do not conflate with reality] When his younger sister disappeared without a trace, the authorities told Wang An they couldn’t file a report until she had been missing for twenty-four hours, and sent him home to wait patiently. But when the twenty-four hours were up, all that returned was a light urn of ashes. His parents refused to believe it and began investigating in secret, but they were in a car accident during their search and both died. Then Wang An himself was framed as the murderer behind it all, thanks to a massive loan he had no idea had been taken out in his name and an accidental-death insurance policy. He was sentenced to life in prison. Unable to bear such a devastating blow, Wang An suffered a mental breakdown on the spot and was sent to a psychiatric hospital. That was when the Revenge System awakened. Following its instructions, he escaped from the hospital, threw himself into the Yellow River, and transformed himself into an uncanny being. Thus began the age of the uncanny, as he launched his revenge against the entire world!
