I Became a God in Tashan!

An immortal from another mountain used a pillow to enter dreams and peer into the dreams of others, reaching the supreme realm of dreams. He created countless little worlds, all contained within jade. Jade is the key, and dreams are the lock. The jade is called the Kuaimeng Jade. Only those who possess it can enter the myriad little worlds, using their souls to take on the form of dreams.
