There are densely lined bookshelves here, each of which is as tall as Murong Yinzhu and two people, and there is no classification, no explanation, all the books are placed in a disorderly manner, some are brand new, some are dilapidated, some are a complete set, and some are only half a volume, a fragment.

Yao Lao's personal collection is really huge, not only huge, but also very old and at least thousands of years old, Murong Yinzhu couldn't help but have a question in his heart, how many years has Yao Lao lived?

At that time, Lin Chenqing said that the life span of the spirit here is only one hundred years, and the powerful one is two or three hundred years, and the collection of books here seems to make the origin of Yao Lao more mysterious.

But at this time, she didn't have time to think about these questions, she had more important things to do, looking for books,

Closing his eyes, his hands quickly sealed, and the aura flowed with it, and after a while, Murong Yinzhu kept the gesture of sealing together, and spit out two words in his mouth: "Gaze." ”

When she opened her eyes again, there was a faint layer of black aura in her eyes, and everything here was very different in her eyes.

Gaze is also the mastery of the Murong family in the previous time and space, and it is best to use it for reconnaissance, tracking and searching. Even the people of the Murong family can master and skillfully apply it, which is an important capital that she can be recognized by the Murong family at that time.

Everything has qi, and the highest realm of contemplation can see the qi of all things, and at the moment, with the cultivation of Murong Yinzhu, what can be seen is that the aura is strong and there is nothing that can be hidden.

These books are all following the spirit, and they must also be contaminated with the spirit of the spirit, and if she wants to find the relevant books of the black and white spirit, she only needs to see that there are black and white qi in these books.

After staring at it, the dark attic in front of him became a colorful one, like a rainbow of light. Murong Yinzhu quickly glanced over, and soon found several books on the cultivation method of black aura cultivators hidden in various corners.

Soul sucking □□, dark arts, blood rakshasa and other spells that are more ruthless at first glance, and these are basically fragments or half volumes, not complete.

Murong Yinzhu considered that he needed to control his instinctive killing and bloodlust, so as not to lose himself, and he didn't care about these too dark spells. She continued her search, and soon saw a worn-out book at the bottom pressed by an orange book.

On this book, there is not a single aura, but black and white colors intertwined, what attracted her attention is that the black and white intertwined aura on this book, like a spiritual snake entangled, suddenly reminded her of the formation on the last page of the Murong family's ancestral training, although there is no color, but the feeling of interweaving is the same.

She pulled the book out of the bottom, and there were three blurred handwriting on the cover: Yin and Yang diagrams.

Turning the first page, there is a picture of a man and a woman, naked, intersecting in a very strange pose. On both men and women, the flow of aura is marked with lines, and there are some mantras and mental methods below.

Then I turned several pages with similar patterns, but the postures of each pair were different, and the aura and mental mantras were also different, and there were nineteen pages of such patterns.

This is a book on the method of double cultivation, Murong Yinzhu immediately understood, skipped those patterns, and turned directly to the last page, this page has no pictures, it is a text description.
