I Have a Qiankun Cave, and the Miscellaneous Spiritual Roots Speed up a Hundred Times

[Serious cultivation of immortality + multiple female protagonists + decisive killing] Xiao Ni traveled through the world of cultivating immortals and became a beggar in Qinghe Town. At the beginning of the collapse of heaven, he was only a servant disciple at the lowest level for ten years. He was called the "most useless" five elements miscellaneous root. Xiao Ni originally thought that his path to immortality would be bleak. Until he fell into a secret hole in the universe, and his fate changed! Inside the cave, ten days in the cave and only one day outside. In the cave, his Five Elements Spiritual Root cultivation speed was actually faster than that of the Heavenly Spiritual Root! Waste elixirs can be turned into top-quality elixirs, and junk exercises can be upgraded into top-notch exercises! In the cave, spiritual plants grow: six days in ten years, one month in fifty years, and two months in one hundred years. Without the blessing of elixirs, his cultivation speed has already started a hundred times! While others have practiced hard for ten years, he has quietly practiced for a hundred years. "Who said that miscellaneous spiritual roots are rubbish? I, Xiao Ni! I use my mortal roots to defy destiny, step on the pride of heaven, and shock the world - I am the way of heaven!"
