After the Ancestor Was Reborn, He Fell in Love with His Nemesis

Zhang Mungdou is a humanoid Horcrux that can introduce souls made by the Kidao family with great efforts. But when the soul was introduced into the vessel eighteen years ago, the soul seemed to be wrong! This body can only accommodate that noble 'soul', not a cat or dog like her! "You are the cat and the dog! Your whole family is the cat and the dog!" Zhang Mungdou became angrier as he thought about it, and kicked the ancestor next to him. "After all, you are still hundreds of years old! You are a thief if you are too old to die!" "But... I am very young." "The bones in your body are so brittle..." Li Yinkong raised his gun. Zhang Mungdou was convinced, "Age has made your temperament more mature and handsome! You are stunningly beautiful! Grandpa, put down the gun, we have something to say!" —————————————————————————— 300 Years ago, Zhang Mungdou and Li Yinkong were incompatible with each other in their previous life. On the eve of the upcoming war, the two's mutual best friend changed midway, causing the two proud men to die in hatred. 300 Years later, time has passed and Li Yinkong is no longer the same Li Yinkong. At that time, the boy had become a three hundred year old 'ancestor', but his nemesis became an eighteen-year-old girl.
