A Sickly Man's Guide to Surviving the Apocalypse

[Sickly, scheming Guide top vs. cold-faced, soft-hearted Sentinel bottom, top-focused] Lu Mian differentiates as the lowest-ranked, F-class Guide. Because the genes of F-class Guides are considered worthless, and to prevent them from contaminating the human gene pool, Lu Mian is to be sent outside the Tower to a place known as the "human meat grinder." No one who goes there has ever come back alive. The good news: on the way there, Lu Mian gets a System. The bad news: it's a sickly System. With this System, he can come down with whatever illness he wants. Lu Mian: No problem. Watch me work. [Contaminant Allergy] There are countless contaminants outside the Tower. They look strange, and people used to be able to identify them with ease. Now they are getting better and better at disguising themselves as humans. They blend in with the survivors, and even the most sophisticated equipment struggles to detect anything amiss. Lu Mian: Can't tell who's a contaminant? Easy. Contaminants that were once so hard to find can now be detected with nothing more than a handshake from Lu Mian. As little red bumps appear on the back of his hand, Lu Mian gives the young girl in front of him an apologetic smile. "Sorry." Then he raises a hand toward the people beside him. "She's a contaminant. Take her away." "Aaaah!" In an instant, the girl's head blooms into a man-eating flower. She snarls and lunges at Lu Mian, but before she can get close, several armed people have already pinned her to the ground. Of course, the System offers more than just that. [Sentinel Craving Syndrome] Lu Mian clutches his chest and shows the medical staff his heart rate of 150. "Quick, my Sentinel Craving Syndrome is acting up. If I can't play with the Sentinel I like, I'll, " Medical staff: "Quick! Tell us what kind you like!" Lu Mian: "Huh? Any kind? I have that much influence?" The medical staff are as frantic as ants on a hot pan. "Your body is now a treasure of humanity. Nothing must happen to you! Whatever kind of Sentinel you want, we'll find one!" Lu Mian: "All right. I want an S-class Sentinel who's 185 centimeters tall, handsome with a dangerous edge, broad-shouldered, slim-waisted, and with a nice butt. It'd be even better if his ID number were 1576320481." * Qu Ziyao is an S-class Sentinel, 185 centimeters tall, handsome with a dangerous edge, broad-shouldered, slim-waisted, and with a nice butt. When he learns that his childhood friend has differentiated as a Guide, he doesn't even ask what rank the other man is. He packs up and runs away. That damn guy has become a Guide... He's definitely going to ruin me! He escapes to a Sentinel training camp completely cut off from the outside world. Because of that, it takes him a long time to find out that Lu Mian differentiated as an F-class Guide. After Lu Mian is forcibly sent outside the Tower, all news of him disappears... Qu Ziyao faints as soon as he hears. Later, the Sentinel camp gains a fearless killing machine who refuses Guides, rejects all rewards, and spends every day going outside the Tower to kill contaminants, returning only once he's killed enough. To everyone's surprise, this famous killing machine catches the eye of a high-ranking Guide, who specifically asks to take him away. Seeing the murderous intent surging in Qu Ziyao's eyes, everyone settles in to watch the show. Qu Ziyao is in a bedroom, waiting for the Guide to "summon" him. He's made up his mind: no matter how powerful the other person is, if they dare touch him, he'll make sure they "Qu Ziyao." A familiar voice sounds behind him, and Qu Ziyao's heart skips a beat. He turns around and sees the person he longs for so deeply, the one he never dared face even in his dreams. Lu Mian smiles innocently, but his mental form has already wrapped itself around Qu Ziyao without the slightest restraint. "Long time no see... Did you miss me?" Theme: Adversity can also be an opportunity.
