I've Become Immortal, Xiu Hammer Immortal

Lin Fan traveled through a different world and bumped into a certain powerful person who took over someone else's body. As a result, the powerful person was forced to hide a black knife. Twenty years later, I realized that I had become immortal even though I had never cultivated immortality but my appearance remained unchanged. Zhutian: "Let me cultivate immortality with you." Lin Fan: "What path does one pursue in cultivating immortality?" Zhutian: "Of course it's the Avenue of Immortality." Lin Fan: "I have become immortal." Zhutian: "..." Lin Fan: "It's not that I don't want to become an immortal, it's that you have evil intentions against me."
