Rebirth from Destruction

In June 2170, the Earth lost contact with "Fernchis" which was 1.5 Light-years away. Chengyu then embarked on a journey spanning 1.5 Light years to find the white moonlight in his life - a girl named Chaoyu who was far away on Fenrchis. But fate seems to have played a joke on them. This journey did not go as smoothly as imagined. Faced with the threat from the universe and nature, what decision will the two of them make? This is a short novel, only 10,000 words, so I didn't divide it into chapters, only the first chapter.
