Through Time Travel, I Am the Best in the World of Cultivating Immortals

Seek Traditional Cultivation of Immortal Literature, Have Spiritual Roots, Climb the Ladder of Immortality, and Cultivate Immortal Literature

I would like to read a book similar to "Sword Cultivator Also Has a Sub-Profession, and He Can Do Everything in Alchemy and Weapon Refining". Looking for traditional articles on cultivating immortals, including measuring spiritual roots, climbing the ladder to immortality, and articles on cultivating immortals. Nowadays, many of them skip these steps. Is there any kind of article on cultivating immortals that is step-by-step and steady? There is no system.
