Spell: I, Jiguo Yuanyi, Grandpa Knotweed

Four hundred years ago, Ji Guoyuan beheaded the ghost king Wuhan one by one, and then was sealed into his brother Shi Tianjiang in Prison Gate by Kensuo. Four hundred years later, he woke up through the seal. Then he discovered that he had a grandson. Hisuhito, a pink-haired sports student, had just swallowed Su Nuo's finger and was sentenced to death by the top magician. Yuanyi remained silent in the seal for three seconds. "Me, my grandson. Who dares to touch?" That day, the ceiling of the high-level meeting room of the magic community was burned through. That day, Gojo Satoru found himself fifth in line. That day, Xia Youjie was pulled out of the abyss by a hand before he died. This is not a "strongest grandpa crushes everything" story. This is the story of an old man who has been waiting for you for four hundred years and finally waits for you. Demon Slayer x Curse setting.
