The End of the Earth: I Escaped from the Earth

The end of the earth, and Li Heyu escaped from the earth in a spaceship. The end of the world? Sorry, this is just the end of the earth. In the vast universe, there is always a place for you, right? *A bit soft hard science fiction* (Due to the limited ability of the author, there are many unreasonable things in professional issues and the development logic of the protagonist. I mainly want to bring the audience a science fiction novel that requires no brain reading)
