My Phantom Beast Is a Cat That Only Goes Meow

Blurb: In the age of the wasteland, Tianyuan Military Academy is the only way to cross class boundaries. The Mobile Combat Department is an even faster ladder to success. But Xia Qiao, a top student from the slums, turns down the Mobile Combat Department's offer and resolutely enrolls in the unpopular field of archaeology. The Mobile Combat Department's teachers are heartbroken to lose a talent, while the other students gloat. Who doesn't know that Archaeology hasn't had a student in three years, and its only professor is a lunatic? Is Xia Qiao an idiot or what?! System: Warning! Warning! Your spirit beast's hunger level has reached 98%. It may go berserk and devour its master at any moment! Xia Qiao quickly soothes her hungry kitten, which is baring its teeth. Her kitten only eats the meat of mutated beasts from the danger zones, and only an Archaeology student ID allows unrestricted access to those zones. Xia Qiao skillfully pilots her mecha through the danger zones. Captured one mutated rabbit. Spirit beast hunger level decreased by 5%. Captured one mutated deer. Spirit beast hunger level decreased by 15%. Captured one mutated brown bear. Spirit beast hunger level is now 0%. Congratulations! Your spirit beast is full! Later, the kitten's appetite grows, and Xia Qiao makes frequent trips to the danger zones. A rumor spreads through the military academy: The Mobile Combat Department has an incredibly powerful spirit beast tamer. Wherever they go, mutated beasts lie dead in heaps! Xia Qiao pats her well-fed kitten, which is lying on its back and begging for affection. Xia Qiao: Nonsense! Awu eats so neatly. How could there be corpses lying everywhere? Kitten: Meow! Meow, meow! Several months later: The Mobile Combat students are surrounded by a horde of mutated beasts and are on the verge of being wiped out. At the critical moment, a spirit beast with a tiger-like appearance and an unusually long tail drops from the sky and tears through the enemy ranks. When everyone gets a good look at its tamer: Everyone: !!!!! Xia Qiao from the Archaeology Department? How is that possible?! Wasn't her spirit beast a cat? Theme: World peace
