Mortal Bones Knock on the Immortal: Born with Mortal Bones, I Have Rebelled Against This Fate

Ning Chen, who has no spiritual roots, became a drug tester and experienced nine deaths. In a desperate situation, he obtained the secret technique of resisting the spirit of mortal bones, exchanging blood and marrow with a mortal body to create false spiritual roots. The false spiritual roots were worse than the five spiritual roots, and knocked on the door of immortality against heaven. He endured and fought for his life all the way, and in the bottom of purgatory, he embarked on a path of cultivating immortality against the will of heaven. (Traditional immortality writing. There is no system and no golden fingers. It is not a cool writing.)
