I, the Demon King of the Abyss, Am Invincible!

The Demon King of the Abyss, Cynthia, was not only trapped in the body of a nine-year-old child when she was reborn, but she was also forcibly bound to the Cute King Development System. [Newbie mission release: Show a cute smile to the guardian in front of you and say "Azathos, I am cute"] Cynthia: This is a humiliation to the Abyss Demon! [Punishment for failure: Random negative status (forced to sneeze for one hour, hair turns rainbow color for one day)] Cynthia tried her best to squeeze out the words through her teeth: I am... Very... Cute! [Greetings to the host, the level of the cute king has been increased by 1 level. Reward: cute coquettish suit. Wearing this suit will increase the chance of success in being cute by 10%] A certain demon king who transformed into a cat-eared girl fiercely threatened his subordinates: Ah, Sa, Tuo, Si, close your eyes, no, accurate, look! Live broadcast room barrage: "Cute contrast! Nuclear explosion!" "Long live His Majesty the Cute King! Long live the cat ears! Long live the princess dress!" Later... Loyal subordinate Azathoth: Ooooooooo, what should I do if I can't restrain myself from wanting to hug the king and lift him up high? The brave man who shouldered the responsibility of defeating the Demon King said nothing and just kept buying gifts. The ruthless God of Destruction said directly: I will protect this cat lady. The evil twins of light and darkness: Xin Bao, does your hand hurt from the beating? Come on, brothers, hoohoo... Cynthia: Why do my subordinates look at me more and more wrong? Did the gods and brave men who shouted at me in the past not take their medicine?
