Even Though a Mortal Has No Spiritual Roots, I Can Still Cultivate Immortality.

Can't you cultivate immortality without spiritual roots? Do I have a plug-in to help me cultivate immortality? How do mortals travel around the world? I am super strong in physical skills and take off by stepping on my feet. How to cast spells without spiritual power? Even my big yellow dog doesn't need me to take action. After all, I am also an immortal. Can you please let me stand up and speak?
