I Have a Taiyin Mysterious Book

The Immortal Lord created the world and established the Yin and Yang Taoism. Taiyin, Shaoyin, Jueyin, Taiyang, Shaoyang, Yangming. The Zhengfa of Taiyin was lost in one day, Yang was prosperous and Yin was declining in the world, Shaoyin Jueyin and other immortal sects were almost eliminated. Li Changxi came with a copy of "Taiyin Xuan Shu". Taiyin methods such as urn method, formation method, body method, magic method, and elixir method are all available. Kill the mountain god, enter the immortal sect, break through the realm and become a saint, combine the body and the Tao, master the yin and yang, seize the heaven and the earth... Suddenly looking back, I realized that the most powerful supernatural power in the world was in the palm of my hand.
