My Deskmate Is the Goddess of War

In 9102, humans have already become the overlord of the universe and discovered that countless civilizations exist in the universe. Humanity continued to annex one civilization after another until it encountered a planet called the "Death Star" - a planet that seemed to contain such power that humans chose to coexist peacefully with it. Our protagonist Xiaojian lives on this planet. The residents of the Death Star are almost from planets of different races. Only Xiaojian himself knows that he has the ability to go back in time and space and travel through his soul. In addition, he also has a female classmate Xu Haibing who was in the same class from kindergarten to high school. Because her fists have the power to destroy everything, Xiaojian calls her the "Female God of War".
