Before Low Tide

Dengqi City has been suspended in the sea of ​​clouds for more than nine hundred years, and it has been kept alive by the memory of being abandoned by all living beings. The person who sent the memory, Cen Jin, received a black box that did not exist - there was no sender, and he was the executor and recipient. During the memorial ceremony, the whole city stood still for seven minutes, and 240,000 people spoke at the same time: "Don't let Tokisu fly past the tenth dawn." Only Cen Jin and the mysterious girl Qi Yao can still move. What's even scarier, she said, is that this is the seventh time they've met. After ten dawns, the truth will return to the world. And Dengqi City will definitely fall.
