Omen of Death:

The artificial sky in the dome area is always clear, but another rain falls in the shadow of the underground city. An APP called "Death Omen" has become quietly popular. It can accurately predict the way a person will die - broken car, burned, cut in half, or delayed. Police said it was malware, until the first prediction came true. Former criminal policeman Lin Du, now just a food deliveryman, witnessed an "accidental" death during an ordinary delivery. He picked up a chip with a tail snake engraved on it, and was involved in a huge conspiracy spanning the dome and the underground.
