After the Sunny Twins—the protagonists Xia Wei [Wei Wei] and Xia Dieqin [Xiao Qin]—defeated the Unhappy King, peace has returned to the fantasy world of dreams, and the Purple Magic Lotus, the source of all energy in the fantasy world of dreams, is in bud. The friends in the dream world were very leisurely and traveled through time and space to the real world, which surprised the Sunny Twins who were missing them deeply. At this time, Ziyi Lanxin and Lanyu Ziyi, who had had their happy energy removed, glowed blue and purple respectively - this was a sign that happy energy was getting stronger. The honeys had a premonition that something big was going to happen in the dream world, so they used Sweet energy to send everyone and themselves back to the dream world. When they returned to the long-lost dream world, everyone was surprised... A magical journey was about to begin again.
