After Being Buried for a Thousand Years, I Was Dug up in My Grave

The fortune teller said that there will be a hurdle when I turn a thousand years old. I didn't believe it, so I picked up a brick and smashed him. In the first thousand years since I was buried in the earth, that is, when I was a thousand years old, I was dug out. I became the first... Undead corpse in this world. (The heroine is invincible/The male and female protagonists are just sympathetic friends/Not the Holy Mother) (Because I am busy with work, I try to keep it updated from time to time. It can be stored on the bookshelf for fattening)
