After Accidentally Feeding the Demon King

[Main story complete] [Blurb] Qun Yu met a young swordsman at the foot of Mount Buzhou. He was gentle, and an especially good cook, so she stuck with him all the way. The swordsman was a lone wanderer with no sect or school. He had made it his mission to eliminate demons and uphold justice. His only hobby was cooking, and his only weakness was being utterly helpless in the face of anyone who praised his food. When Qun Yu followed the swordsman to Evil Spirit Mountain, they had just set a pot over the fire to make soup when an ancient demon lord, who had cultivated for a thousand years, burst onto the scene. Demon Lord: “I am the foremost of the ten thousand demons of the Evil Spirit Sect! You lowlifes are lucky enough to be my first meal after my return. Get down on your knees and thank me at once!” He burst out laughing. The gale swirling around him overturned the huge pot of radish and crucian carp soup the swordsman had made for Qun Yu. The swordsman stepped in front of Qun Yu, only to see her staring at the soup spilled across the dirt. Her eyes suddenly turned red, and an overwhelming demonic aura blotted out the sky. Day turned to night, and all creation bowed low. The demon lord was so scared he didn't dare breathe. Yet when she spoke, her voice was still as sweet and clear as jade: “Damn it, I hate show-offs.” They say that only Qun Yu, the ancient Demon King Jun Yu sealed beneath Mount Buzhou, had ever refined a demonic god's body with the power of chaos. Her demonic aura was entirely under her control, and even the Demon-Slaying Divine Sword could not tell her apart from a demon god. Behind Qun Yu, the swordsman couldn't help touching the Demon-Slaying Divine Sword he had carried for years, the same sword he had used to chop beef bones, scrape fish scales, cut scallions, and mince garlic for her: ... Divine Sword: “A thousand years of slaying demons made my name famous throughout the martial world, and one cooking session ruined my good name Q_Q.” - The Six Realms had known peace for tens of thousands of years, but the Demon God's awakening plunged them into turmoil. Each realm stood ready for war, and the situation was as volatile as fire and water. Qun Yu returned to the Demon Realm and gathered a group of handsome young demons, all skilled cooks, to attend her. Even so, she still often thought of that snowy figure atop the mountain. The person who had once been the gentlest in her heart had publicly declared that they were through. Their blood feud, passed down through generations, could not be erased. If they met again, they would face each other with blades, and fight until one of them died. She never expected to meet him one day in the eastern kitchen of the Demon Palace. “What are you doing here?” Qun Yu asked in utter surprise. “Where are all those handsome guys I hired?” The demonic blood on Lu Heng's sword had yet to dry. He replied coolly, “I killed them all.” Qun Yu stiffened, remembering his words: “If we meet again, we will face each other with blades and fight until one of us dies.” He had already slaughtered dozens of demons today. Perhaps she would be next. Sure enough, Lu Heng looked ready to kill again. He pointed his sword forward and told Qun Yu to toss him the live chicken behind her. “It's almost time to eat.” The man let the malice fade from his eyes and said quietly, “The kitchen's full of smoke. Go wait outside.” “Divine Sword: I knew something was off when he said, ‘If we meet again, we'll face each other with blades and fight until one of us dies.’” “Divine Sword: Turns out he just wants this sword to cook for the Demon King for the rest of her life. Hahaha!” (It threw back its head and laughed, tears gradually welling in its eyes.) [Reading Guide] 1. Mistakes a Demon King for a sweet little girl, and devotes herself to feeding her. 2. A wild, ridiculous, sweet, and satisfying story that really lets loose. The heroine is sealed at first and grows stronger over time. She's the strongest in the universe and charges through life with a single word: brute force. Two powerful characters meet and pretend to be weak in front of each other. There's plenty of romance. 3. The logic follows the plot, there are tons of author-created details, and the story contains a lot of colloquial language. Be warned. [Coming soon: the next fantasy novel, Does the Ancestor Need a Lackey Junior?] [Blurb] “Welcome our new ruler to the throne of the Underworld! May your might command the Nine Abysses and keep the Netherworld in eternal peace!” The ghosts shouted their congratulations and surrounded their newly appointed Ghost King, Dongfang Huan, as she took her seat on the highest throne in the Underworld. Dongfang Huan turned around, her beautiful face full of confusion. Help! She's a two-time graduate school entrance exam candidate. Yesterday she was still wrestling with calculus, and today she'd seen a ghost. Math really can scare you to death! And it got worse. Right after Dongfang Huan ascended the throne, she was sacrificed. Powerless to resist, she was thrown into the Nether Sea as an offering to the legendary ancestor of the Underworld, said to be incredibly vicious and terrifying. The green lotus karmic fire burned softly. The ancestor lounged within it, and to her astonishment, he looked exactly like the brilliant senior student she'd worshipped before she transmigrated. Dongfang Huan cautiously asked him, “What's the polar-coordinate form of the equation for a lemniscate?” The ancestor frowned and stared at her for a moment, then conjured a string of symbols with magic: r2=a2cos2θ Dongfang Huan burst into tears of joy and grabbed the hem of the man's clothes. “Senior! How did you turn into this kind of ghost? Waaaah...” To be fair, the look was pretty cool. She looked again. Ah, even cooler. No wonder he was the campus heartthrob. He was still so handsome even after he died. If he could teach her how to solve problems, he'd be even more handsome... The ancestor: “...” What was she thinking about? As the Ghost King, didn't she know that he, the ancestor, could read minds? [Reading Guide] A ghost obsessed with the graduate entrance exam X the ancestor who created heaven and earth. The heroine transmigrates; the hero is a native. Theme: Love one another and benefit one another; love without distinction.
