A fantastic purple city appeared in Xiaoyi's dream. Unknown flowers covered the purple city and the surrounding area was red. Look up at the dreamy purple city among the red carpet-like flowers. "I've been waiting for you for thousands of years. Why don't you come and accompany me?" There was infinite expectation in that desolate voice. It makes those who hear it cry. When Xiaoyi opened his eyes, tears were streaming down his face. "Purple City! Where is it? Why am I crying? Who is the speaker?" Out of curiosity, Xiaoyi embarked on a dream-seeking journey.
