There Is a Sect of Cultivating Immortals in My Ancient Book

[Traditional cultivation of immortality + mortal flow + no system + space + friendship + slow heat] I have an ancient book, which can change shape on the outside and contain space inside. If you hide in it, the old monster Yuanying won't be able to find it. It is the safest place to live. The bookstore in the space contains various high-level techniques, which can be called the configuration of an immortal cultivating sect. Can this technique purify the elixir and improve its quality? Practice! Can this skill change one's appearance and conceal one's cultivation? Practice! Can this exercise be used to strengthen the body just by taking a bath? Very good! … I want to cultivate immortality, but I cannot be a solitary person who practices in seclusion all day long. I need friends, I want a Taoist companion, and I want to live a colorful life in the world of immortality.
