An Ordinary Fox Becomes an Immortal

For any fox to cultivate nine tails and become an immortal, he needs to survive three heart tribulations and nine thunder tribulations. He saved me three lives, and I worshiped in front of the Buddha and practiced hard for five thousand years, and finally got the chance to see him. In the first three lives, he died for me, but in this life, he let me die for her. Am I the only one who is wrong in this world?
