Mistaking the Demon Lord for His Junior Sister

The eldest daughter of the Ten Thousand Immortals Sect, Pearl, whose father is the leader of the largest sect in the world of immortality and whose mother is Nuwa, was born with advanced cultivation, a beautiful family background and a happy life, so she was nicknamed "Ruyi Niang". But on the night of her sixteenth birthday, she had a dream. In the dream, she turned out to be a fake daughter in a book about true and false daughters. The real flesh and blood of the Ten Thousand Immortals Sect is actually the new junior sister who has entered the sect. In the storybook, because she was worried that her identity would be exposed, she did many bad things to suppress her junior sister. Until the truth finally came out, she was kicked out of the Ten Thousand Immortals Sect, lived on the streets, and died fighting with wild dogs for food. When Mingzhu woke up and found out that everything in the dream was true, she went to reveal everything to the master of the Ten Thousand Immortals Sect and his wife. The little junior sister was recognized by the sect leader and his wife, and she continued to stay in the Ten Thousand Immortals Sect. The sect leader and his wife of Wanxian Sect treated Mingzhu as intimately as usual, but every time Mingzhu looked at her little junior sister's pretty but slightly thin face, she felt that she owed her a lot. So, at the apprenticeship meeting, the junior sister said she liked her personal jade pendant, so she gave it to her without hesitation; at the Wanzong gathering, the junior junior sister was slandered, so she stood up to protect her; in the green secret realm, the junior junior sister was seriously injured and fell into coma, so Mingzhu gave her medicine and guarded her all night. The longer she spent with her junior sister, the more Mingzhu found her cute. She is beautiful, well-educated, and very clingy. She likes to pull her sleeves and call her "sister". Until that day, the Ten Thousand Immortals Sect was besieged by the entire world of cultivation, and when Mingzhu was in despair, he saw his little junior sister in red, with a golden blade, protecting her behind her. The pale sunlight illuminated the golden blade striking the lightning star, and the figure of the man holding the sword was unruly. Only then did Wushuang suddenly understand two things. The younger junior sister turned out to be a young man. And that young man was actually the legendary red-clothed devil who killed people without blinking an eye. * Demon Lord Rong Mu had his identity changed when he was young, suffered a lot of hardships, and developed a twisted and world-weary temperament. At first, Rong Mu stayed with Mingzhu just to see how interesting it would be if this "Ruyi mother" who had robbed her of her identity would have no more happiness in her life. But he didn't expect that later on, he would be willing to hold all the good things in the world in front of her. He only wished that she would live happily for many years to come.
