After Swapping Bodies with the Demon Lord

[Seeking advance readers for After Being Claimed by a Tentacled Villain. Blurb at the end.] Xie Weining transmigrated into an old-school xianxia novel as a vicious female cannon-fodder character. The original owner was the daughter of the Immortal Emperor. She was madly in love with the male lead and hated the female lead. She not only neglected her cultivation, but also devoted herself to fighting with the female lead for the male lead's affection and for power, earning everyone's hatred. To win the male lead's attention, she even volunteered to attack the Demon Venerable. Instead, she was left half-dead, corrupted by demonic energy, disfigured, and stripped of her cultivation. She opened her eyes at the very moment the original owner led a group to confront the Demon Venerable and his people at the edge of the demon realm, arrogantly believing she could take them on. A group of demonic cultivators was approaching. Xie Weining: ... She had transmigrated too late, and her cannon-fodder fate was too rotten. What was the point of playing this game? She was done. She chose to lie flat and wait to die. Then, out of nowhere, a violet-grade tribulation lightning bolt struck. When she woke again, the whole world had changed! (Not really.) "My lord, the Left and Right Protectors are fighting again today!" "My lord, are we still attacking the immortal realm?" "My lord, ten more people have gone mad from cultivation!" Xie Weining looked down at her flat, firm chest and felt her abs. Her expression turned grim. "I need to rest." Meanwhile... A crowd gathered around a certain "Xie Weining," who had just woken from severe injuries, their voices irritated. "What did you do? How is the Demon Venerable?" "Look at the mess you've made. All you do is cause us trouble!" "How could you get so badly injured on your own turf? You've disgraced the entire immortal realm!" "..." The person's expression darkened, their voice cold. "You're too noisy. Get out." Everyone: "How dare you talk like that!" In the next moment, the other person's brows furrowed with fury. They drew their sword and charged. *Extensive original worldbuilding; identities are temporarily switched at different stages *One-on-one romance After Being Claimed by a Tentacled Villain Wei Zhi transmigrated into an old-fashioned novel as a vicious female lead. The male lead used her until her family was destroyed, her reputation ruined, and she died miserably in the street. She opened her eyes in the middle of the original owner's reckless attempt to die, just as she was punishing an obstacle on the male lead's behalf and about to break his hands and feet. The man was forced to kneel at her feet. He was covered in wounds, yet still held his back straight, his eyes deep and silent. He had the face of the novel's powerful villain! Wei Zhi hurriedly let him go, then tried to earn some goodwill. She treated his wounds with care, looked after him, and did whatever the villain wanted. She just hoped that if she ever got into trouble, the powerful villain might help her out a little. Until one day, struggling with the original owner's specialized coursework, she offered a high salary to hire a tutor. A certain powerful villain showed up to apply for the job. Beneath his aloof exterior lay a wealth of knowledge. He was gentle with others, and not only that, he had a... cough, a very good physique, and was skilled in combat too, even if he could be a little strange at times. She gradually fell under his charm. Later, Wei Zhi realized she often felt uncomfortably restrained while sleeping at night, and sometimes woke up feeling strangely sticky. Then, after an accident... Amid screams of terror, wreckage lay piled before her, and a foul stench assaulted her nostrils. A horrifying shadow was cast beneath the lights. Countless enormous tentacles crawled across the walls, wrapping around the entire ship in an instant. Everyone was as insignificant as ants. Wei Zhi instinctively took a step back. "P-Pei Cong?" Pei Cong casually wiped the blood from the corner of his mouth. His smile never reached his eyes, and his voice was low. "Good students aren't afraid of their teachers." Wei Zhi: "!!" Nobody told her the villain in the novel was a tentacle type too! Theme: Recognizing one another's different identities, understanding one's true feelings, and clearing up misunderstandings
