Ten years ago, there was a huge explosion in Ningluo Lane that shocked the entire Sa Feng City. Only three people survived at the scene: You Cheng, Ban'er and Zhou Yan.
The death toll reached more than 580 people, alarming the central government and attracting widespread attention from major media.
The defendants Yang and Zhang were only sentenced to ten years in prison for unknown reasons.
The victim, Zhou Yan, and his lawyer left the country on the second day after the court verdict, and there is no more news about them in Asia.
After the explosion, one of the survivors, You Cheng and Ban'er, was seriously injured and the other was blinded, so the matter went unresolved.
Until two people received a strange letter.
