Underwater Ancient City and Praying Girl

Xu Qi was extremely convinced that he was being followed by a fish. During class, during sports, and during part-time work, he is followed by the other party all the time. One day, she couldn't bear it anymore and finally pulled him out. I saw the fish speaking, and his voice was as innocent and weird as a child's. He said he wanted to take her to see the legendary "Underwater Ancient City". Xu Qi was slightly dazed. She heard her grandfather say it. Only when the sun is as red as fire, severe droughts spread, and the earth is cracked, can people see the "ancient underwater city" like a mirage. It... Is the end of the world.
