There's Nothing Wrong with Me Being Stronger After Living for a Thousand Years, Right?

Everyone in Wucheng knows that there is a strange girl Tang Yin in the antique street. She loves to chew popsicles and is lazy all day long. Others just treat her like an ordinary little girl. No one knows that she is the owner of the Duerxuan that has been passed down for thousands of years. With a blood contract, she can claim old debts from a hundred years ago. During the Republic of China, the Qin family borrowed the Nine-Eyed Mother Cauldron in exchange for family wealth, but they refused when the time came. A blood mist enveloped the manor overnight, and no one in the Qin family returned alive; A strange female corpse with a human face floats from the river. The Red Butterfly Sect uses living people to refine biological weapons in an attempt to unblock the thousand-year-old mountain monster; The Third Prince and Yin Yang Taoist who came to provoke her, and all those who did evil, became nourishment for her to increase her cultivation. The Imperial Master of Tianqingmen secretly hid the cauldron, and various evil forces set up killing arrays, thinking that they could surround her. Little did he know that the ferocious monk, giant dragon, and vine demon were all soul slaves under her command. Wherever the blood mist swept across, there was no opponent. Detective Jiang Tiantian is her only worldly confidant. Special units offer her privileges, and rich and powerful people vie for them. She just chews candy lazily and looks at the ugly people watching. The world deceives her because she is young, not knowing that she holds the yin and yang in her hands and is in charge of sorting out the good and evil in the world. Debts must be paid, and evildoers must die. The century-old grievances of the Nine-Eyed Mother Cauldron, as well as the national master hiding in the dark, will one day come to her in person to settle them one by one.
