Fantasy Three Kingdoms: The Xuanmen's Beloved Little Junior Sister Is Reborn

When Sui Sui comes down the mountain to visit home each year, her grandmaster worries about her safety and gives her a magical treasure. Whenever she runs into trouble, she can summon everyone from the Mystic Sect, even the grandmaster himself. The first time she uses it, she summons the Mystic Sect's guardian beast, which transforms into a human and joins her for an all-you-can-eat buffet. The girl and beast nearly eat the restaurant into bankruptcy. The owner even pulls out a stack of cash and pays them to go eat across the street. Whenever Yin Suisui has nothing to do, she tears open rifts in space and time, leaving powerful figures in every realm loving and hating her in equal measure.
