Very few monks entered the seventh floor. Apart from him and the resident elders, there were no other monks.

Picking up a book called "The Mystery of the Golden Spirit" at random, Liu Yu held it carefully and silently looked through the unobstructed parts.

He was fascinated by it for a moment, and was gradually attracted by the content, forgetting the passage of time.

"Wow"

For a moment, there was silence in the room, except for the sound of turning pages from time to time.

This is a classic book on the study of the characteristics of metallic aura, written by a foundation-building monk thousands of years ago. This man later became the Golden Core Elder, but has now fallen.

It is recorded in the classics that this elder conducted detailed research on metallic aura during the foundation building period.

Experiments were conducted on the morphological changes and inner property changes of metallic aura under various environments.

The strangeness of the angles and the genius of the idea are very inspiring!

After reading the first page, Liu Yu was attracted by the content and couldn't help but want to watch the following content.

He couldn't help but bring "The Mystery of the Golden Spirit" closer to his eyes, and read it word for word.

A quarter of an hour passed quickly, and before I knew it, I had finished watching the free content.

In Liu Yu's heart, she couldn't help but feel that her intentions were still unfinished.

I really want to use my meritorious deeds to redeem the entire book "The Secret of the Golden Spirit" right away, and take it back to the cave to study it in detail.

In the past, he only knew that the metal type was sharp and focused on killing, and these were just superficial things.

If you are not a monk of the metal transfer system, most of them only understand it to this extent.

But a book called "The Mystery of the Golden Spirit" opened a new door for Liu Yu, and he learned about the world of metallic spiritual energy.

Really benefited a lot!

"Twenty points of merit."

After taking a look at the exchange price, Liu Yu could only put it down with regret as it required twenty merit points.

You must know that the "Tianchen Pill" that can increase the chance of forming a pill by 10% only has 20 points of merit.

But this book "The Mystery of the Golden Spirit" also requires twenty points of merit, and the price is really shocking.

"If a monk who majors in gold-based exercises gets this book, his strength will indeed increase greatly."

"Unfortunately, I am a fire monk."

Although the price is expensive, Liu Yu felt relieved when she thought about the profound content inside.

Although the privileges of true disciples can be reduced or reduced, they still require fifteen points of merit. Now that the body training method has not yet been found, he can only put it aside.

Liu Yu admitted that if this was "The Mystery of the Fire Spirit", then he would have to get it no matter what.

"pity."

With strong regret in his heart, he carefully put "The Secret of the Golden Spirit" back, for fear of damaging this rare immortal cultivation book.

He picked up another classic and continued to look for the body-training techniques he needed.

Although the bookshelves on the seventh floor were full of very rare knowledge about cultivating immortals, Liu Yu couldn't wait to sweep them all away.

However, the current meritorious service is really limited, so I can only reluctantly put it down and quickly browse through the classics and jade slips to find what I need.

Suddenly, he picked up a yellowed and damaged classic, and his eyes lit up.

"Thousands of refinements of true power!"

With a strong sense of expectation in her heart, Liu Yu opened the homepage and slowly flipped through it.

This "Thousands of Refining True Skills" is exactly the body training method. It is divided into nine levels and can be practiced directly to the late stage of Jindan.

After cultivating to the level of mastery of the technique, it is enough to compete with the golden elixir perfection monks. It is easy to use ordinary magic weapons by force. It is indeed a rare high-grade body training technique.

Completing the sixth level of cultivation, which is the "hundred-refinement of the physical body" level, is enough to surpass ordinary foundation-building peak cultivators.

However, if you use your bare hands to defeat a high-grade spiritual weapon, you still won't be able to hold on for too long. You can only hold on for an hour or two. Any longer and your life will be in danger.

Although this "Thousand Refining True Kung Fu" is far from Liu Yu's expected choice, it is still much better than the few ordinary body training books in his hand.

Not long after searching on the seventh floor, he found something like this, which made him even more excited.

"Do not disappoint me."

Thinking like this, Liu Yu put down the classics, picked up the next one and continued searching.

"Golden Muscle and Jade Bone Technique", "Dark Demon Blood Body", "Yin Fire Body Refining Technique"

After searching for a while, he found several more high-grade body-training techniques, all of which were at the same level as the "Thousand-Refining True Kung Fu".

These ten or so body training techniques are very rare in today's era. If it were not for the power of the sect, it would be impossible to see them at the same time.

After practicing to the foundation-building stage, you will be able to gain a certain advantage when facing Dharma cultivators of the same realm, and it is no longer a problem to receive magic weapons with your bare hands.

But it's still the same problem. With Liu Yu's current strength, magic weapons are no longer taken seriously.

The ideal technique in his mind would be one that can physically defeat high-quality spiritual weapons without causing any damage to oneself.

Even, it is the best spiritual weapon!

With some regret, Liu Yu put down the jade slip in his hand and picked up the next one.

As time passed, all the classics and jade slips on the four bookshelves had been browsed.

Only the last of the five bookshelves was left. None of the body-training techniques he had found so far were very satisfactory, which made him feel a little inexplicably nervous.

"."

Shaking her head slightly, with a somewhat complicated mood, Liu Yu picked up another blue classic.

This classic book is made of unknown animal skin, and there is a chill immediately when you hold it, as if you are holding cold black ice.

"Taiyin Refining"

Turning to the first page of the book, four dark gold fonts came into view.

The handwriting is vigorous and powerful, with an extraordinary aura remaining, as if the writer's will, like the blazing sun, still resides on it.

This classic was so extraordinary that Liu Yu couldn't help but hold her breath, and then read on.

"Not bad."

Just reading the first few pages made him feel happy.

This "Taiyin Form Refining" is really unique. He actually thought of using the power of Taiyin in the moonlight to refine the body. Its power far exceeds the dozens of previous body refining techniques.
Chapter completed!
