"Oh, let me take a look." Lin Feng immediately became interested when he heard that it was a spiritual energy file collected internally by the National Security Bureau.

This information is classified as an SS-level file within the National Security Bureau, and only innate masters and a few leaders can see it.

Lin Feng immediately looked at the file. The file was very rich in content, with a very comprehensive explanation of Reiki. It explained many of Lin Feng's questions, and it also contained many methods of practicing Reiki.

The method of practicing Reiki has gradually been lost after the end of the Han Dynasty. Today, there are basically no methods of practicing Reiki. Unexpectedly, Guoan actually has a collection of several methods of practicing Reiki.

However, judging from the annotations on the side, Guoan did not regard these spiritual energy cultivation methods as treasures, but only regarded them as important information.

Really top-secret documents will not be placed on the Internet. They are all written in writing and placed in the most secure safe, and cannot be seen on the Internet at all.

Because Reiki Kungfu cannot be practiced, Reiki has been considered non-existent, so these documents are only an important piece of information for Guoan, not magical secrets.

But it was completely different for Lin Feng. He knew the existence of spiritual energy and was able to imbue his body with spiritual energy. Therefore, for Lin Feng, this information was extremely important.

Among the documents related to spiritual energy collected by Guoan, not counting the fragmentary pieces, there are a total of twelve complete classics, namely: "Dan Cauldron Xuanhuang Jue", "Golden Juice Yuanshen Method", "Baicao Su Wen Jing", "Xu Cao Su Wen Jing"

"Ling Taishang Induction Chapter" "Hundred Birds Sword Control Technique" "Qiankun Fiery Tribulation" "Ice Mysterious Yin Technique" "Shadowless Invisible Wind Chasing Technique" "Taiyi Supreme Purity**" "Seventeen Ways to Broken Spirits" "Withered Wood Heart Sutra"

》"Five Thunders Zhengfa".

Among them, "Alchemy Cauldron Xuanhuang Jue", "Golden Juice Yuanshen Chapter" and "Baicao Su Wenfa" are all classics for refining alchemy. In Taoism, this kind of exercises belong to the Neidan School, which is used to refine elixirs and eat elixirs, thereby improving cultivation.

In order to obtain the road to immortality.

The remaining nine books contain all kinds of spiritual energy cultivation techniques. The most powerful among them is the "Taiyi Shangqing**". The most powerful techniques in this "Taiyi Shangqing**"

, lies in its completeness. It contains all the formulas from practicing Qi to the realm of gods. If you practice in the ancient era when spiritual energy is abundant, you can practice in accordance with "Taiyi Shangqing**" to reach the realm of gods.

It is the supreme method for practitioners.

Although the rest of the techniques are not as good as "Taiyi Shangqing**", they are all spiritual energy cultivation techniques, and each has its own mystery.

In the ancient times, these classics were the secrets of magical skills of various sects, and they were never passed on to the outside world. Any one of them would cause a bloody storm if it spread to the world. However, who would have thought that in modern times, the spiritual energy has weakened, and there are no more secrets of magical skills.

People practice, these magical classics that were robbed in ancient times have been shelved by the national security and openly hidden in the Internet.

I'm afraid that even the people from Guo'an have just collected these uncultivable magical skills and secrets as antique calligraphy and paintings, and no one knows their true value.

No, now someone knows their true value. At least Lin Feng knows the true value of these magical skills and secrets.

Lin Feng roughly looked through the outlines of the twelve classics. After knowing the general situation, he read each one in detail.

For Lin Feng, the value of these twelve classics is truly immeasurable. They are supreme treasures, but no one knows them.

"Danding Xuanhuang Jue" records a kind of elixir called Shengyi Dan. The Shengyi Dan is made of one yin and one yang, two exotic beast inner elixirs, and is refined with a variety of spiritual herbs. It is effective in treating internal diseases.

Trauma has miraculous effects. The sword energy damage on Lin Feng's chest can be treated with just one profit and loss pill.

The alchemy technique of the Prosperity and Loss Pill is also clearly recorded in the "Alchemy Xuanhuang Jue". The alchemy technique is not difficult, but it is a pity that the main material of the Profit and Loss Pill, the alien alchemy, is very scarce, and in modern society, it is not available

Inner Alchemy.

What is the inner elixir? The inner elixir is another name for the golden elixir. That is, after the alien beast reaches the golden elixir state, the golden elixir is produced in the body. This is the so-called inner elixir.

Because of the reduction in spiritual energy, powerful alien beasts have long since died, and even their corpses have rotted away. There is no way that any inner elixir can be left behind.

However, the current strange beasts cannot reach the realm of golden elixir due to the reduction of spiritual energy, let alone the generation of inner elixir.

Even if there are golden elixir beasts, with the power of the golden elixir beast, who can kill the golden elixir alien beast? You must know that the golden elixir is a level higher than the innate existence, and a golden elixir alien beast is enough to run rampant in China.

Humans can be defeated.

It's such a pity. The effect of the profit and loss pill is very powerful. One profit and loss pill is enough to cure Lin Feng's internal injuries. But it is a pity that without the inner pill, the profit and loss pill cannot be refined at all.

The Profit and Loss Pill is considered a relatively low-level elixir in the "Elixir Cauldron Xuanhuang Jue". Even this low-level elixir cannot be refined now.

"Qi Nourishing Pill!"

Lin Feng saw another powerful elixir, the Qi-nourishing elixir, which was made from five inner elixirs and spiritual herbs. It could improve the cultivation level of those who took it below the level of the golden elixir.

An ordinary person who knows nothing can only take two Qi-nourishing pills to reach the innate realm. You must know that it will take at least several decades for ordinary people to cultivate to the innate realm. The effectiveness of this pill is too terrible.

, it’s going to be outrageous.

But it's useless no matter how against heaven, because without the inner elixir, this medicine cannot be refined.

Lin Feng's eyes turned red when he saw it. The pills recorded in this book were so outrageous that no matter who saw them, they would be tempted, and Lin Feng was no exception.

There are too many good elixir recipes in the back, but no matter how good the elixir recipe is, it is useless. The lowest elixir here also requires the use of inner elixir as the main ingredient. The more advanced ones also need the soul of alien beasts to be used as medicine. Damn, this

Planting elixirs cannot be refined by ordinary people at all. Just take a look. If you want to refine them, there is no way.

Although I didn’t gain much, I did gain some insights.

The "Golden Juice Yuanshen Method" is different from the "Alchemy Cauldron Xuanhuang Jue". The "Golden Juice Yuanshen Method" does not cultivate the outer elixir, but uses oneself as a furnace and spiritual herbs as medicine to refine the medicinal power and cultivate the inner elixir.

It is a very unique cultivation method, and it is also a very unique alchemy method. However, the "Golden Juice Yuanshen Method" does not cultivate external elixirs. The power of the elixirs cultivated will be absorbed by oneself and will only benefit oneself.

Lin Feng read "Golden Juice Yuanshen Method" once, and then started reading the next book "Baicao Suwen Jing".

"Baicao Su Wen Jing" is somewhat similar to "Dan Ding Xuan Huang Jue", but they are different. Most of the elixirs in "Dan Ding Xuan Huang Jue" are refined from internal elixirs as the main medicine, while "Baicao Su Wen Jing"

Most of the elixirs recorded in the book are mainly refined from various spiritual herbs.

The elixirs recorded in "Baicao Su Wen Jing" are no worse than those in "Danding Xuanhuang Jue". For example, "Baicao Su Wen Jing" records a kind of elixir called Yiqi Dan. The effect of Yiqi Dan is as good as nourishing Qi.

The pills are equivalent, but the effect of the Qi-Yi Dan is stronger than that of the Qi-Nourishing Dan. For ordinary people, taking one Qi-Yi Dan is enough to impact the innate realm.

But similarly, the main material of the Qi-Yi Dan is also difficult to obtain. It requires a thousand-year-old wisteria orchid. Millennium-level spiritual grass is difficult to find in the world. Where can you find this kind of thousand-year-old wisteria orchid? Because there is no spiritual grass, the Qi-Yi Dan is also difficult to obtain.

Refining.

There are many elixirs with astonishing effects in the back. Also because they are indeed spiritual herbs, these elixirs cannot be refined.

In the second half of "Baicao Su Wen Jing", the main material of the elixir has once again changed from spiritual grass to the spiritual flesh of various exotic animals, such as thousand-year-old rhinoceros horns, colorful snow deer skins, and three-headed animals.

The leopard's brain is so dizzy that it actually still exists

To use Qilin as medicine, the blood of Qilin is used as the main medicine to refine Tianlin Pill. Tianlin Pill is a top-level elixir that can strengthen the physical body. Taking Tianlin Pill can make oneself extremely powerful and have extremely strong defense power.

, is the favorite elixir of body refiners.

"Hey, it's the last page, Dragon and Phoenix Immortality Pill?" Lin Feng turned to the last page of "Baicao Su Wen Jing", and there was a record of a pill called Dragon and Phoenix Immortality Pill on the last page.

Dragon and Phoenix Immortality Pill is made from dragon brain and phoenix marrow as the main medicine. Taking it can extend your life by three thousand years.

Three thousand years... How many years does a human life last? A pill can actually extend a person's life for three thousand years. This is three thousand years. It is indeed worthy of the title of longevity pill.

Lin Feng's eyes turned red again, almost bleeding. Those pills that increase strength are not rare to Lin Feng, but this Dragon and Phoenix Immortality Pill is completely different. This is a pill that increases lifespan. Take one.

With one pill, you can live for three thousand years.

Three thousand years is an extremely long time. Being able to live for three thousand years is really not much different from living forever, at least for ordinary people like Lin Feng.

Of course, the Dragon and Phoenix Immortality Pill only increases lifespan, allowing people to live an extra three thousand years. As for whether they can live for three thousand years, it is not necessarily true. There are many factors that can cause people to die early. If someone is killed early, then the life span of three thousand years will also be lost.

It's just a joke.

Even so, it is undeniable that the effect of Dragon and Phoenix Immortality Pill has a fatal attraction for Lin Feng.

With the Dragon and Phoenix Immortality Pill, not only can you live an extra three thousand years, but your parents, family, lovers, and friends can also live an extra three thousand years. The whole family can live happily together for three thousand years. What a fatal temptation this is. When I think of that beautiful scene,

Lin Feng was almost suffocated by the picture.

But... **, where can I get the brain and marrow of dragon and phoenix? These two creatures, dragon and phoenix, have long been extinct on the earth. Let alone the brain and marrow of dragon and phoenix, even dragon poop can't be found now.

.

I would have known better not to read this book, it would make me feel extremely aggrieved.

There is obviously a recipe for immortality, but there is no material for making the elixir. It would be strange if you don't feel aggrieved.

Dragon brain and phoenix marrow... Lin Feng suddenly fell silent. He remembered one thing. Are the dragons and phoenixes of the Bright Continent the same species as the dragons and phoenixes of the earth?

If you use dragon brain and phoenix marrow from the Bright Continent to refine the Dragon and Phoenix Immortality Pill, will it still be effective?

This is what Lin Feng suddenly thought of. There are no dragons and phoenixes on the earth, but there is still a bright continent.
