Astronomer Yan Luo discovered a star between the constellations of Ophiuchus and Serpens.
It is not in any star catalog, has no number, and is like a blank ID card. What's even weirder is that only he can see it.
He named it "Xu Su".
Late at night on the fourth day, a white light brought him to the Chronos system. A man named Qi Guanche told him: The star has always been there, but it has never been seen. Yan Luo is the chosen observer and has three days to explore the starry sky.
After three days, he can choose to go back - all memories become a dream from which he cannot wake up.
Or stay - disappear from the face of the earth and become someone who never existed.
Purpose: A fateful encounter across the universe, finding a home in an unfamiliar star field
