The Beloved Junior Sister of the Immortal Sect Is Actually an Undercover Agent in the Demon World?

The three-year-old little princess of the demon world is bound to the system and goes undercover in the fairy sect with the hope of the entire demon world. Wow! I want to hide my identity, live well, learn the top immortal skills, and conquer the three realms! Nai He is extremely talented and has first-class strength. The scraps of metal that he held at hand were the divine swords from outside the realm. The casually contracted burrowing mole is the Qiankun beast. The sales of the talisman paper he drew at random became a hit in the world of immortality. The puppet made at random can challenge the Golden Elixir Dzogchen in a single fight. Jiang Qingtian: Raising your hand is not a sign of apology, it's a senior and you still have to practice. Accidentally, the little princess from the demon world turned out to be the hope of the entire immortal world. Everyone in the world of immortality: This woman will definitely be able to conquer the demon world and protect the peace of the three realms in the future. Jiang Qingtian pointed at herself with a confused look on her face: Who is it? This princess?
