The Demon King's Competition-Level Fairy Pet

In this world ruled by demons, the immortals fight each other for the amusement of the demons. Minglang is such an "immortal fighter" who has won many battles. Her adopter was Li Xiao, the king of the prosperous Demon Kingdom and the son of the Demon God. Minglang dedicated his entire life to him. She honed her martial arts day and night to gain victory for his reputation, kill countless of his kinsmen for him, block countless sword blades for him, and destroy all enemies for him. Finally, he stabbed his sword into his chest. When he was about to die, Minglang only heard Li Xiao say: "The immortal clan is not worthy of trust..." It was all in vain after all. When she woke up again, she had not become Li Xiao's "dog", and the people she cared about were still alive in front of her. This time, she woke up. The demons and the immortals were incompatible with each other. She spurned herself for committing herself to the demons and betraying her own race. She is no longer afraid, she wants to subvert the world, chop off the heads of the demon clan, and truly bring a bright future to the fairy clan. More importantly, she must make the cold-blooded demon king who arrogantly trampled on her life pay the price. She prostrated herself in front of Li Xiao again, hiding her burning scheming, and said with respect and joy: "I will die for the Lord even if I die!" Li Xiao nodded casually as before, "Grow up." Li Xiao's training supplements poured into her hut like running water. Li Xiao's name prevented outside demons from easily humiliating her. Li Xiao's identity allowed her to accumulate the strength to resist around this noblest demon clan. In her previous life, she had done everything for him. This time, she was going to eat him up and wipe him clean. No longer worried about Li Xiao's favor, Ming Lang realized that he could live so easily. Did Li Xiao forget himself in the arena? Walk back by yourself and go hunting. Li Xiao went to adopt a new immortal clan again? Great, hurry up and conquer your fellow tribesmen while no one is watching. Li Xiao is unkind to his harsh training? I want to kill you with the martial arts you taught me. … Compared to Li Xiao's attitude, the safety of her fellow tribesmen and the development of the Immortal Clan Alliance are her most important concerns. Although it is inevitable to kill her fellow tribesmen in the arena, no one standing in front of her has their own blood on their hands. She is willing to bring peace to them. With her decisiveness, superb martial arts skills, and beautiful face, Ming Lang quickly became the favorite to win and was sought after by the violent demon clan. She had countless followers, including old enemies who became more and more courageous as she fought, demon nobles who kept showing goodwill to her, and a secret resistance alliance... She was glad that she could still live so happily. However, Minglang discovered why Li Xiao was different from his previous life? Occasionally she would see him pacing anxiously late at night, and when she turned around, she would always see him staring at her. His face was actually a little worried when he was injured in the battle. Her restraint and alienation actually made his expression hurt? Li Xiao became inexplicably angry because of the proximity of other demons? Did Li Xiao take the wrong medicine? In any case, this is a good thing. Li Xiao is pampering her more and more, which is perfect for her to form a resistance army. The war started, and finally it was time to break up. The strong wind howled, just like the day of the tribulation in his previous life, when Ming Lang rushed into Li Xiao's room, and he sat upright in plain clothes in the light of thunder. The sword blade pierced his chest, but he could still laugh. "That's fine..." Blood splatters and great revenge is avenged. "... Have I paid it off?" He held the sword and his body gradually slipped away. Ming Lang stood by the window, suddenly in disbelief. He...
