Xinghai Yiyin

In 2250, humans received a signal 5,000 light-years away. It was the last breath of another civilization. Three generations have set out, waited, and searched for this. Some people spend their lives on a spaceship, some people spend fifty years opening a letter, and some people finally arrive in that direction - only to find that the owner of the last words has long since turned into dust. The sea of ​​stars is vast, and the echoes are endless.
