One day, several teenagers suddenly vanished from Yanjiang City. A few years later, they returned. Not long after their return, gigantic creatures began appearing all over the world, and a planet from a distant universe sent a warning of impending disaster, declaring that it had awakened. From then on, a miracle called hope would bloom on this planet. (The author's writing isn't very good. Also, this is a fictional world. Finally, I wrote this on a whim for fun, so please don't take it too seriously, including the setting.)
