Light Wader

In 2041, while working the night shift at an observatory at an altitude of 4,300 meters, gravitational wave astronomer Ye Mingzhou decoded an extraterrestrial signal from cosmic noise coming from 2,300 light-years away. The signal has lasted for 74 years but has been secretly sealed by governments. Humanity thus formed the spaceship "Phoenix" and embarked on a journey of interstellar contact.
