I Mistook the Violent Boss for the Protagonist and Raised Him [Book Transmigration]

Zhou Qian had been single for twenty years when he was suddenly transported into a cultivation novel, saddled with the task of raising the protagonist, no less? Fine, he could raise him. It was like gaining a little brother. Though this "little brother" had it pretty rough: his spiritual root was destroyed, his cultivation was crippled, and he was paralyzed from the waist down! No matter, Big Brother would heal it all! What? He wanted miraculous pills and peerless techniques, too? Fine, fine, he'd get it all for him! Good little brother, mwah~ Zhou Qian really poured his heart and soul into raising this little protagonist! Yet just as the protagonist's cultivation kept improving and his fame kept growing, the mission progress... remained stuck at a bizarre 10%. Zhou Qian couldn't make head or tail of it. Until one day, he discovered a secret: It turned out that every full moon, his pitiful, seventeen-year-old "little brother" would secretly grow up and transform into... Wenren Yan, the bloodthirsty, murderous Lord of Ten Thousand Demons from the book. Zhou Qian: "..." QAQ I raised the wrong person. _ That night, the fifteenth day of the lunar month, the moon was full. The sect leaders had laid an early ambush in Zhou Qian's bedroom, waiting for the Demon Lord Wenren Yan to show a hint of murderous intent so they could hack him to death with their swords. But they saw no murderous intent. Instead... there was plenty of heat. On the bed drenched in moonlight, the legendary demon lord, with silver hair, red eyes, and a bewitchingly beautiful face, was pinning their poor Sect Leader Zhou down and kissing him. His hands were wandering, too. This was just too much! With things about to get out of hand, the sect leaders all started crying: I should be under the car, not inside it T^T Zhou Qian, who still hadn't seen them make a move, started crying too: ??? Do something! Come on, do something!!! ★ Blurb from the gong's perspective: Wenren Yan was struck to death by heavenly lightning in his previous life. Reborn, all he wanted was to nip the "protagonist" in the bud, before he could cheat his way to summoning a lightning tribulation in the final battle of the future. But even after getting a second chance, this young "protagonist" was still absurdly favored by the Heavenly Dao. Wenren Yan seriously injured him, but suffered a backlash himself. Not only was his body reduced to that of a child, his spiritual root was destroyed, his cultivation crippled, and both his legs left disabled. With death seemingly his only option, then... "Are you Feng Huayang of the Yuheng Feng clan?" Beneath the ruined temple gate stood a young man with a sword on his back, silhouetted against the light. His beautiful eyes curved gently as he looked at Wenren Yan with concern. Looking at the familiar face, Wenren Yan felt his heart stir. He hid the killing intent in his eyes, put away his ferocity, then, in a hoarse voice, bit his lip and answered through tear-filled eyes, claiming the name he hated with all his heart: "That's me." *Heh. Sorry, but your good master belongs to me in this life. Beautiful madman gong x foul-mouthed, unconventional shou. One-on-one, both virgins. Reader notes: 1. Low magic, low magic, low magic! 2. Updates whenever inspiration strikes. Just have fun. 3. Fake master-and-disciple relationship, younger gong. -- Blurb written on 2019.10.28 -- Theme: How does love begin?
