Interstellar Empress: the Pet of the Paranoid Mr. Jiang

She is known as the strongest god of war in the interstellar federation, and can decide the life or death of a civilization with a single thought. When she opened her eyes again, she turned into Yun Shuyue, a high school girl who was cowardly and on the verge of death. In the past, her enemies ridiculed her, trampled on her, and treated her like an ant. They didn't know that for an unsolvable math problem in class, the formula she scribbled down could lead to technology for the next hundred years. They didn't know that a malicious frame-up on campus and the trap she set up could cause a wealthy family to collapse overnight. She just wanted to take revenge in a low-key manner and find out the truth about her death, but she accidentally broke the taboo known to the whole school—— The sickly and noble young master Jiang Huaizhou looks like a gentle breeze, but in fact he is an abyss that even she cannot see through. When everyone was betting on when she would kneel down and beg for mercy, But Jiang Huaizhou blocked her in a corner of the laboratory, his fingertips entangled in her hair, and his breath was hot: "For that question, you used the 'Xinghui' super-dimensional theorem... Right?" "Yun Shuyue, or should I call you——" "Respected, Your Majesty the Empress?" Later, the artillery fire of the interstellar expeditionary force hung in the sky of the earth, Standing in front of thousands of mechas, he looked back and asked her: "My Majesty, is this time conquest or... Save?"
