When he returned to his room, it was already early in the morning, but Lin Yu didn't feel sleepy at all. He just wanted to quickly figure out the contents of the black book.
Under the candlelight, Lin Yu quickly flipped through the black book.
"Essence?"
"I see!"
The beginning of Black Book spends a lot of space introducing something called essence.
According to the description in the book, essence is divided into innate essence and acquired essence.
The innate essence is innate, it is innate, and represents the origin of life. Damage to the innate essence will lead to qi deficiency and physical weakness, and death if the damage is too severe.
Acquired essence can be absorbed from the outside through specific means.
The yang energy that I heard from the scarred man before is actually part of the innate essence.
According to the book, the innate essence is a state of yin and yang. Once the innate essence separates into yin and yang, it means death is not far away.
For example, when a person falls into extreme fear, the innate essence of yin and yang will be differentiated. Once the yang energy escapes, the person will lose his vitality.
Commonly known as being scared to death.
The reverse is also true. If a person is killed by an external force, the innate essence in the body will begin to differentiate between yin and yang, and yang energy will automatically merge into the world of heaven and earth.
"Yang Qi is the energy of growth and the energy of the body, while Yin refers to the physical body..."
"I thought Yang Qi was the Qi of the living and Yin Qi was the Qi of the dead. It turns out I was wrong."
After reading the introduction of Jingqi, Lin Yu finally understood that Yang and Yin here did not refer to life and death, nor did they refer to men and women.
Yang transforms Qi and Yin transforms form.
Yang here refers to energy, while yin refers to matter, the material that makes up the body.
The unity of yin and yang is the life form.
After knowing this, Lin Yu finally understood why eating a recently dead animal could absorb its characteristics and use it for his own use.
This is because the innate essence of the newly dead animal has not yet differentiated, and what it absorbs is actually the innate essence of the animal, which is the origin of its life.
It is this source of life that gives oneself certain qualities unique to that animal.
And if the animal's innate essence has been exhausted long ago, it will not be able to obtain traits even if it absorbs all of it. For example, if an animal dies of old age, illness, or disease, its innate essence will have been exhausted long ago.
Lin Yu continued to look down, and as he looked, he saw another concept called Yin Qi.
"So this is how Yin Qi comes from?!"
Yang represents the energy of a living being, and Yin represents the body of a living being.
After death, the innate essence of a living body is divided into yin and yang, and the yang energy automatically returns to heaven and earth, leaving only a pure yin body.
However, this does not mean that the energy in it has completely dissipated. In fact, a part of the energy of a dead living body is still consolidated within its tissues.
This part of the energy will slowly dissipate, and there is a certain chance that it will be consolidated into surrounding dead objects, such as metal rocks, etc.
This energy is called Yin Qi, and is usually found in grave goods in tombs.
"Yang Qi is energy, Yin Qi is also energy, the essence is the same."
Lin Yu touched his chin and continued to read the black book.
In the following pages, demons and trickery are mentioned.
There are four kinds of evil things in the world: monsters, demons, treacherous creatures and monsters.
Among them, demons are the collective name for all non-human creatures with spiritual intelligence, such as flowers, birds, insects, fish, plants, trees and animals, all of which can be cultivated into demons.
Its method of cultivation is to absorb the innate essence of other living beings through special methods and refine it into demonic energy to increase cultivation.
The stronger the demon's aura, the higher its cultivation level.
There are two categories of demons, one is demons that can transform into humans, and the other is demons that maintain their original form.
The former absorbs the innate essence of humans, while the latter absorbs the innate essence of non-human life forms.
There is no distinction between the two kinds of demons.
It's just that some demons like human life and want to blend in, while some demons are used to staying in the mountains and wild forests, and choose different cultivation methods based on different purposes.
"It seems that the skunk I met last time has been cultivating by absorbing people's innate essence for many years. It came to seduce me because it wanted to absorb my essence."
Lin Yu put down the black book, leaned back on the chair, and thought about Yuan Neng.
Yang qi and yin qi are both energies, and monster qi, according to the book, is also a kind of energy, which is unique to monsters.
Lin Yu discovered that all this energy seemed to be able to be used for his own purposes.
When I killed the skunk last time, I got 110 points of energy. I didn't know it before, but now I know that these energy came from the remaining demonic energy of that monster.
"So, Yuaneng is the collective name for all energy?"
Lin Yu touched his chin, frowned and thought for a while, then sat upright again and continued to read the black book.
The following content is all related to mystery.
Gui is a pure energy body, formless and without quality.
It needs to constantly absorb external energy to maintain its existence. Of course, absorbing energy can also make it continuously stronger.
There are only two kinds of energy that Gui can use, Yang energy and Yin energy.
As long as the former can be absorbed, it can be directly converted into energy that it can use, while the latter needs to be processed using special means.
However, the book does not introduce how Gui uses Yin Qi for his own use, nor does it introduce the origin of Gui.
Not only that, the content about demons and monsters is also completely missing.
Mainly because this is an introductory book on spiritual practice and only introduces content related to spiritual practice.
The essence, yang energy, yin energy, etc. are all related to the following cultivation methods, so they will be introduced in detail.
As for why demons are introduced in such detail, it is because the cultivation methods of demons are similar to those of humans.
"Could it be that the evil things transformed into the corpses of brothers He Wen and He Wu are monsters?"
"Or is it a demon?"
Lin Yu held his forehead and thought.
Those two evil things are obviously neither monsters nor ghosts...
"No, those two things can't be demons or monsters."
The reason why demons and monsters are not introduced in the book is because they have nothing to do with things like Yin Qi, Yang Qi, and Essence Qi.
And those two evil things can absorb Yin Qi.
"Forget it, we'll learn more about this later. Let's first see how those people practice."
Lin Yu put the question behind him and continued to read the black book.
Most of the next book is all about spiritual practice, that is, human practice.
It is mentioned in it that the way of human cultivation is to absorb acquired essence from the outside world and refine it into source energy.
However, the book does not talk about how to absorb the acquired essence at all. It only talks about how to refine the source qi and how to use the source qi.
Not only that, Lin Yu also found that this book did not mention how to enter the path of spiritual practice at all.
"Not everyone should be able to practice. If everyone can practice, then the imperial court can completely open the door to practice, greatly expand the number of practitioners, and wipe out all the monsters and ghosts in the world."
Lin Yu guessed that there must be some kind of innate condition that limits human beings, resulting in only a very small number of people being able to practice.
In other words, a special ritual is needed to allow a person to enter the path of spiritual practice.
"We will discuss this issue later. First, we need to find out what Origin Qi is."
Lin Yu thought about the source of energy mentioned in the book.
The book says that source qi is refined from essence qi. Under normal circumstances, what is refined is acquired essence, that is, essence qi taken in from the outside world.
Under special circumstances, you can also refine the innate essence in your own body.
However, refining the innate essence will lead to a reduction in lifespan, so no practitioner would do such a stupid thing unless absolutely necessary.
"That Yu Chirong suddenly burst out with a huge force. It seems that it was because he had refined the innate essence in his body."
Lin Yu nodded slightly and continued to read the black book.
