Journey to the Stars

This is a real universe that existed before the protagonist and operated completely on its own - from the Gobi Desert to the end of the galaxy, from the change of dynasties to the birth and death of civilizations, everything had been running for hundreds of millions of years before the protagonist arrived. The protagonist, Lu Chen, is just a mortal who started in the wilderness. He does not rebel against nature, do not dominate, and does not want to be a savior. He only relies on his mortal body to travel across the galaxy, experiencing joys and sorrows, making atonements for his mistakes, and guarding desperately. Finally, from the beginning to the end of the universe, he lives his own life completely. His path is the journey of mortal bones stepping on the stars, a witness to the birth and death of the universe, and the story of a mortal living his own life in the vast galaxy.
