City's Transformation into Immortality

For eighteen years, he was a fool in a small mountain village. He was looked down upon and bullied by everyone. He was beaten and his memories of his past life were awakened. It turned out that he was actually a veteran cultivator who had gone through 9999 times of tribulation, his soul was immortal, and the dogs he had raised in several lifetimes had become immortals, but he had to start re-cultivating for the ten thousandth time! In this life, he will definitely become an immortal! (It seems that I also thought so in my previous life)
