Dreamland and Cyberpunk

In the big city of 2076, a funeral tore apart Su Chen's peaceful life. His father died, and the whereabouts of the mysterious chip called Relink was unknown. He was reduced from a rich young man to a helpless abandoned son overnight. He was also closely monitored by Lucy, a top hacker, and was forced to step into the quagmire of the Edgewalker. What's even more bizarre is that every night when he goes to sleep, he experiences a completely different life. (Concise version: Mainline cyberpunk, the dream world is equivalent to the infinite world.)
