Traveling Across the Stars: I Sell Potions to Recharge the System

[Interstellar+1v1+Mecha+Zerg+Modern Cute Girl vs Interstellar Laoden~] Hua Nuo traveled through time. As soon as I opened my eyes, I was sitting on the spaceship. The last second I went to sleep, I was binding the system and started a life of cheating. The next second he opened his eyes, he woke up and traveled across the interstellar space to become a military cadet. I thought that working nine to five every day and working overtime from time to time was hard enough, but I didn't expect that Star Academy does not treat students as human beings. That's really girls, and boys are used as mechas. The main thing is to be fair between men and women, and treat the students as intelligent machines that don't rest 24 hours a day! Mecha, supernatural powers, medicine, thousands of years of interstellar history, commanding operations... And many other subjects are waiting for you to learn. I feel dizzy after going to class every day, and I have to be forced to do trading tasks by breaking the system every day. For system tasks, I just do it perfunctorily every day. The more the dog system urges me to do tasks, the more perfunctory I become! The main character is a rebel! (It mainly talks about the college life where the heroine goes to school, and the interstellar war (it talks about how those (gai) sluts of the Zerg race) do weird things to drive the human race out of their star domain.) [The heroine studied in the academy in the early stage, and after graduation, she did missions and fought against the Zerg on the front line of the First Army.
