Ruan Qintian, a child of a medical family, and Luo Shuxuan, general manager of Yuexin Group, grew up together since childhood. They have a deep relationship and are like sisters. The two of them had agreed on a spontaneous trip since they were young, and had been working hard for several years. When they were about to fulfill their agreement, they both died in a plane accident on the way to their destination. The two woke up and arrived in a strange world. The people here cultivate vitality, fly to the sky and escape from the earth, and are full of fantasy... I look forward to how the two of them can survive in this world.
