Starting as a College Student, I Turn the World Upside Down

[Cutting-Edge Tech + One Female Lead + Interstellar War + Sci-Fi + Dyson Sphere]

"Why did you start a war?!"

"I didn't. The people just wanted them strung up on lampposts!"

"They're only pitiful bugs. Why are you slaughtering them?"

"Rumors, all rumors! I was just making reasonable use of resources!"

"Then explain what happened to the Andromeda Galaxy Cluster!"

"What does that have to do with me? I just sent a little thing over there!"

It all started with this college student.
