After Becoming an Ordinary Doctor [ABO]

[Nontraditional ABO, 150,000 words already written, so dive in without worry] Wen Yushu arrives three thousand years after humanity fled the wasteland. As expected, Earth has exploded again. Humanity has evolved into six sexes, and he has the honor of becoming a fugitive on the wanted list. Wen Yushu: ...Is this right? No identity papers, illiterate, no useful skills... Just after escaping the death line, Wen Yushu steps into the United Star Alliance Academy, only to find himself in a total disaster of a major. Medical Intervention Officer: a specialty focused on restraining out-of-control AO individuals, and the one with the highest casualties among the beta background characters. At school, an honor student who is an O pretending to be a B begs him to secretly make an inhibitor during their heat; His unruly, big-breasted B roommate suddenly gets pregnant, runs away with the baby, and asks him to deliver it; Off campus, a powerful O threatens him into performing an illegal gland-removal surgery; An Alpha who's also undercover asks him to help with a sex change... Wen Yushu: ...I only know how to kill people! Where's the promised invincible soldier-king story? At first, everyone thinks he's a weakling Beta who got lucky and survived. Until he turns the earth to scorched wasteland, the battlefield into a sea of blood, and saves humanity from catastrophe, becoming the savior of the galaxy. [Interstellar Broadcast: Feared and respected by alien races, an honored guest of the intelligent machines, humanity's savior. He should be the light of the galaxy!] [Galactic Prophet: A heretic to the faith! An aberration among the races! A scheming politician and conspirator! He's the greatest threat of all!] [Deep Space Observer: Politicians love and hate him, not only because he knows every family's secrets and has a pretty face. Can't you see that he doesn't even blink when he kills?!] Wen Yushu sits atop a heap of wreckage, casually wiping the slime from his hands. He smiles faintly. "But I'm really just an ordinary medical officer." * The dawn of humanity, the Star Alliance's top officer, the youngest general... Xie Changying is recognized throughout the galaxy as Wen Yushu's greatest nemesis. And yet... "You have to take responsibility for me." The young Alpha buries his face in his nemesis's neck. "My dad said an Alpha's neck is only for his wife to touch..." On the day they first met at school, this beta had pinned him to the ground and held his neck down in front of everyone. The warmth of his body had passed through his latex gloves to Xie Changying's glands, and even his breath had blown brazenly across his hair. Then the beta had casually said something that infuriated him beyond measure. Now Wen, Evil, Yu, beta, Shu can only pat his glands and tug his collar down helplessly. "Go on, bite me." How could anyone outplay you? The Alpha says nothing, only silently brushing his lips against the smooth nape of his neck. But his scent can never linger there. Then, how about... [Revised 26.5] 1. A very nontraditional ABO! It's very much my own take. 2. Bottom protagonist, Alpha-Beta(?)-romance, no pregnancy or childbirth. The timeline is long, so both characters' personalities and the way they interact will change over the course of the story! They're growing! 3. One-third plot, one-third career, one-third romance, one-tenth author being goofy. A story written purely for the author's personal tastes. Since the protagonist is a doctor, the plot will involve some mentions of side characters' relationships and romantic histories, but they won't be the focus. 4. To be added. Theme: A doctor's heart is full of compassion!
