**The top ten unsolved mysteries of the Interstellar Federation Military Academy:**
1. Why does Ning Xiaoxia's mecha always sneak into the command dormitory area in the middle of the night?
2. Why does Yu Xiuchen's tactical board have sweet orange-flavored pheromone residue?
3. What exactly could the two of them "fix" in the mecha maintenance cabin in three hours?
——Until a certain actual combat exercise, the entire army witnessed a shocking scene:
Commander Yu Xiuchen, known as the "emotionless fighting machine", dismantled half of the Zerg warship with his bare hands and ran back to the base carrying the acid-corroded "Firefly" mecha. Ning Xiaoxia's frantic roar came from the cockpit:
**"Let me down! What you are carrying is my fucking engagement ring!!"**
**※**
**Ning Xiaoxia**, the genius Omega of the mecha engineering department, daily status:
? Fried Lab (3 times a week)
? Stealing desserts from the cafeteria (2 times a day)
? Paint cat ears on the mecha of the cold commander Yu Xiuchen (continuous output)
**Yu Xiuchen**, the devil instructor of the tactical command department, daily status:
? Rejected 90% of Ning Xiaoxia's design plans (but would secretly improve the remaining 10%)
? "Accidentally injured" all the Alphas who were close to Ning Xiaoxia during the exercise (the grudge book is full)
? Pretending not to notice that a love letter was stuffed into his combat uniform (the handwriting looked very familiar)
**When the whole school is betting on when they will puncture the window paper——**
As the Zerg army pressed on, Ning Xiaoxia activated the ultimate mecha that he had secretly modified for three months: "If you survive this time, you must explain it to me! Why did you leave without saying goodbye ten years ago!"
The last words Yu Xiuchen said before pressing the self-destruct button were:
**"Because my first reaction when I differentiated into Alpha was to mark you."**
(Army-wide announcement: "New regulations prohibiting kissing between technicians and commanders on the battlefield" by the angry and bald principal)
""Report! Ning Xiaoxia dismantled the toilet door of the command ship again! "
"Let him tear it down. "Yu Xiuchen didn't even raise his head," he said after he demolished the door last time, the Zerg communication code was deciphered. "
""Why is your mecha called 'Firefly'? "
"Because someone said..." Ning Xiaoxia kicked the cockpit, "No matter how dark the universe is, you can find your way home if there is light. "
"Yu Xiuchen suddenly took off the microphone at the post-war commendation meeting: "Ning Xiaoxia, I can now answer you publicly - my answer to the question ten years ago was "yes".
(The whole place is silent)
Ning Xiaoxia: "Fuck! What I'm asking is, "Do we want to take the military academy exam together?"
