Xia Fei was finally placed by Tu Ying, and the collapse of the passage trapped him in this chamber.

Xia Fei's fingers are keen to feel that there seems to be text behind this silver metal piece, so he opens it and looks at it.

"How about it? You're scared of me? In fact, there is another way to the outside world in this chamber. It depends on you. You can't find it. Ha ha. "

Xia Fei's wrist was lifted and the metal piece was bounced out.

Whoosh!

The silver sheet of metal crossed a straight line and sank into the surrounding rock, forming a standard scalpel incision.

Xia Fei bit his teeth. Tu Ying is not only ferocious, but also very mischievous. He has come up with such a way to torture himself. There is a passage in the chamber of secrets. Where is this passage? Just now I have explored this place twice and found nothing abnormal. If there is a channel, it must be in an extremely hidden place.

He picked up the thin manual in the glass cover. However, things had to be done step by step. Xia Fei decided to see what the last thing Tu Ying had left behind.

The manual is only about 30 pages. A thin small book is held in the hand without any weight. The paper is made of a special plant fiber. It smells of a faint blood smell, as if this book has been in the slaughterhouse for many days.

"Origin?" Xia Fei gently read the words on the cover page. The font is ancient and elegant. It is easy to see that it was written by hand, not printed by machine.

Generally speaking, because of its special status and inheritance, it is not possible to use machines to print large-scale. If it is mass-produced, there is no secret to say. Therefore, most of the secret books are secretly copied by safe people, and this [source] is obviously the same.

Xia Feifan looked at it. He read the book very fast and understood it far beyond the ordinary people. He read the thin book in less than two minutes.

With a sigh, Xia Fei finds that this book is not a skill, but a way to absorb the power of the universe!

The legend of the power of origin is a kind of special energy produced in the formation of the universe. After the formation of the universe, this energy will disappear quickly. However, a mysterious energy crystal absorbs a lot of the original energy of the universe in this process and stores it. Until now, this is the heart of the spirit.

The reason why the adjudicator's trade union is so strong that it can continuously deliver a large number of high-level soldiers to the trade union is that they have mastered the knack of how to make the human body absorb this pure energy body. Xia Fei knew it very well when he was in the Tianjue training camp. However, he was worried that excessive intake of this energy would lead to physical damage. Xia Fei has always been concerned about this behavior It is self-consciously restrained. After all, the body is the capital of revolution. If the body function is damaged because of greed, the gain is not worth the loss.

The opening of the seventh brain region is an example. Although Xia Fei completely opened the seventh brain region, he lost the opportunity of promotion. It can be seen that there is a balance in the universe. There is always a relationship between gain and loss. The more you get, the more you lose.

This manual teaches the key to how to make the human body absorb the universe's original energy. Once mastered this technology, as long as the soldiers whose foundation is not too bad will make great progress with the help of the spirit heart!

Of course, there is a cost to improve one's accomplishments in this way. First of all, the total amount of energy consumed must be strictly controlled. This is like pouring water into a pool. If it is too full, it will overflow. Everyone knows that.

Secondly, the original energy of the universe is too violent. If it is absorbed directly, it will bring an unbearable burden to the body. Therefore, the energy must be transformed into the radiation that can be absorbed by the human body, and then injected into the user's body.

If a person wants to absorb 100 units of standard energy, he needs to spend at least 1000 units of energy to achieve the goal, because a large part of energy will be wasted with body fluid and air.

Considering the high price of spirit heart, it is a kind of money burning behavior to improve oneself rapidly in this way. Only when the adjudicator's Union is rich, can it use this high-end technology to a small number of members.

There are three kinds of energy transformation in the heart of the spirit. One is called the curvilinear line. This kind of conversion requires the lowest technical requirements and is the easiest to achieve in reality. This method is used in the practice room of the adjudicator's Union.

However, although the curvilinear line is cheap, it does not transform the heart of the spirit very well. If the human body absorbs a large amount of such energy wave line, it will easily cause vomiting, coma, and even serious damage that cannot be repaired for life.

And it makes people more grumpy. The ubiquitous wave line is like a raging fire, fierce but not easy to control.

Xia Fei breathed a sigh. The original side effect of curving speed wave line was so fierce. Fortunately, he didn't take in a lot of this energy in Tianjue training camp, but he didn't know about the moon song. Shen Dong and his wife had been exposed to the wave line for a long time in the past two years. If they had any side effects, they would have to be warned.

If the first method is like burning one's body with fire, then the second method is like a million miles of ice. Although the original energy becomes milder after transformation, it still brings strong side effects.In addition to physical damage, the biggest problem with the second method is that it can make users feel tired of the world and even commit suicide.

It is said in the book that people who use the second way of energy intake will become withdrawn and have a sense of boredom about the people and things around them. The whole person is gloomy. If they continue to eat energy, they will cause great mental trauma, nerve frustration, hallucination and other mental diseases.

Xia Fei shakes his head. This second method is not advisable. Although the side effects of curvelet are also very strong, they will not cause mental injury at least. In many cases, mental pain is much more unbearable than bloody wounds. It is said that mentally retarded children are more happy, but who would like to become mentally ill or mentally retarded?

The reason why human beings are different is that we can think and learn. If we lose this ability, what is the difference between human beings and walking dead?

There are also worldly weariness and suicidal tendencies. Xia Fei thinks that it's better to live if you want to die, and suicide is even more unacceptable. Therefore, he doesn't appreciate the second way.

The last one is much more perfect than the first two, called gentle conditioning.

Using this method can completely avoid the disadvantages of the first two, neither harm the body nor become tired of the world, but this gentle conditioning method is not perfect.

And its name is completely different, gentle conditioning method not only will not make people become gentle, but will make people become bloodthirsty!

Using this way to improve one's own cultivation will form a subconscious thinking similar to religious fanatics. Even if one becomes indifferent to life, he will not even frown if he becomes indifferent to human life.

Xia Fei said with a smile: "yes, this last gentle conditioning method is very good. There is a purple spirit heart in the space ring, which contains a lot of original energy. When you go out from here in the future, you might as well try it."

He didn't care about the side effects mentioned in the book. In Xia Fei's consciousness, all these pathological manifestations were caused by the lack of firm will. Assuming that a person's will is as firm as iron, he will never be shaken by small side effects. Xia Fei has always been confident in himself and is not afraid of these conscious things, as long as there is no problem with his body, All problems can be overcome by our own will.

Continue to scroll down, Xia Fei found that to convert the spirit's heart to mild energy wave land is simply demanding. It not only requires extremely high equipment, but also has to use high-purity purple spirit heart, and its energy loss ranks first among the three ways.

Even the price of the smallest heart of the purple spirit can easily be hundreds of millions. Such a huge amount of money is spent and wasted. There is no such way to burn money.

Presumably, the adjudicator's Union also has a similar material in hand, so it has the ability to use the spirit heart to quickly improve the membership level. Only because the cost is too high, they use the first way which is relatively cheap.

When you close the manual, Xia Fei takes it into his arms. All the four items left by Tu Ying have arrived. Now what needs to be considered is how to get out of here.

Ghost's face was melancholy, and obviously he had no better way.

The air has become a little cloudy. Oxygen consumption is a very serious problem in a closed space. Without oxygen, even if Xia Fei has unique skills, he can do nothing.

There is a small air tank for both the nameless combat suit and the newly acquired bloodthirsty icy God combat suit. Previously, Xiafei has consumed part of the oxygen reserve of the nameless combat suit. In addition, he still has enough oxygen to support himself for about an hour. In addition, Xia Fei estimates that he has only three hours left for himself.

Three hours of time can be with the woman you like to be exhausted, you can eat chocolate to eat abdominal distension, you can practice a set of thorns, breath, plus the spirit of the beast code, but this time for a life is very small.

According to the original route, Xia Fei once again carefully inspected the secret room. Every crack and even every particle of dust would not be let go. Moreover, he was trying to control his heartbeat and blood flow to prevent unnecessary consumption.

Disappointingly, this time there is still no harvest, the stone wall is solid, where is the shadow of the road?

Extraordinary times must be dealt with by extraordinary means.

Xia Fei sits on his knees in the chamber of secrets. His brain is running fast. He thinks about every detail since he entered the passageway, from the structure of the secret room to the human nature of Daotu Ying.

Xia Fei tries to turn himself into Tu Ying and think about it with his thinking.

"If I were Tu Ying, where would I arrange the secret channel? How would it be concealed? "

"Is it just crazy enough? Does Tu Ying have other requirements and hopes for those who will inherit his collection? "

As time goes by, Xia Fei is trying to think and calm down. The more he is in the critical moment, the more calm he has to face!

The air is getting cloudy, and the time left for Xia Fei is very few. (to be continued, please visit www.qidian.com , more chapters, support authors, support legitimate reading! )www.novelhold.com , the fastest update of the webnovel!
