When I was woken up by my sister, I found that I had come to a strange place. After asking around, I found out that this city is called "City of China". If you want to go back, you must find a mysterious person in Qili Village, and use the Key of Qili to open the Seven Star Box, get the Qili Song, and sing it. If you are one of the lucky ones, you can leave here.
My sister and I are looking for this mysterious song sheet. After getting to know twins like us - Tang Jun and Tang Yu, we agreed together that we would not back down until we found the Qili song sheet. When I developed a crush on Tang Jun, I discovered that my sister and I had special physiques. The number of opponents continues to increase, and a wave of difficulties is coming to us. Tang Jun and Tang Yu ignored the dissuasion of their families and helped us avoid the discrimination of the residents and the attacks of the enemies. We entered a cave and accidentally discovered a beautiful place. But when I walked in, I realized that this was a planned trap. Suddenly, my sister and Tang Yu disappeared mysteriously again. While looking for them, I was ambushed by the enemy again. In desperation, I just ran away and accidentally got poisonous mist and fainted. When I woke up again, I was the only one around and came to a strange place. The villagers stared at me and avoided me all day long. I found the letter Tang Jun left for me in my pocket. He told me to go to Zhaojiacun quickly. But I don't know where I am, so I can only stay in the village. A lot of puzzles are coming to me, strange villagers, my special physique, strange places, missing Tang Yu and sister, and Tang Jun's letter. Where should I go...
