In the Forest of Death, the blood-colored moon hung high, gradually moving westward, and the cold wind brought a few screams of unknown monsters from time to time, setting off the midnight extremely mysterious.

Alan sat under a sturdy ancient tree and watched "Fight to Victory" seriously. At this time, Alan already knew that "Fighting to Defeat the Duel" is a fighting qi exercise, and if you want to practice, you must first have fighting energy, what is fighting energy? Fighting spirit is a kind of energy that naturally exists between heaven and earth, just like various attributes in magic, it is a kind of energy between heaven and earth.

As a layman, the first thing to do is how to feel the existence of Dou Qi and try to attract it into one's body, and then be able to practice according to the exercises. Alan put the little golden book into his shirt, then sat down cross-legged, and began to try to feel the so-called vindictiveness.

According to the "Fight to Victory", you must first enter a state of emptiness, and then you can feel the energy around you. Alan closed his eyes and slowed down his breathing, and after ten minutes, Alan suddenly felt a strange itch on his back, so his state was disrupted, and Alan quickly scratched his hand a few times, and sometimes began to close his eyes and feel it.

However, it may be because Alan is a little anxious, and he is a little restless, and he can't feel the so-called fighting energy for a long time. With a long sigh, "Alas, am I not suitable for cultivation?" Alan didn't feel the existence of the fighting spirit for a long time, and he was slightly disappointed in his heart.

"Huh, by the way, don't I still have this?" Alan took out the dark red beads he got from the skull of the Red Mouse Monster, how can this also be the Monster Crystal Nucleus? There must be energy in it, I can try to absorb the energy in the Monster Crystal Nucleus into my body.

As soon as he thought of it, Alan put the Warcraft crystal nucleus on the palm of his hand, then covered it with his other hand, closed his eyes, and felt it again. This time Alan quickly entered the state, a trace of fiery energy emanated from the palm of his hand, and at the same time he felt the same, Alan also saw a very pure red energy suspended in the palm of his hand, Alan knew that this is the energy in the crystal nucleus of the demonic beast, this kind of body is very mysterious, Alan is obviously with his eyes closed, but he can see that the red energy is beating, just like a flame.

Alan tried to get close to the red energy, close observation, the red energy gave people a very warm feeling, Alan tried to attract the red energy into his body, using his mind, controlling the red energy group little by little, first peeling off a trace of red energy from the red energy group, and then carefully controlling it into his body.

The red energy slowly flowed into Allen's body along the meridians on his arm, through his arm, chest, and stopped at the lower abdomen, and a trace of red energy gathered together, and then continued to grow, gradually gathering into a group, at this time Allen found that the red light cluster in his palm had become smaller and smaller, and gradually dimmed. Alan opened his eyes and glanced at the Demonic Beast Crystal Nucleus in his hand, which had dimmed a lot, and there was no longer any brilliance flowing.

It seems that the energy has run out, but it feels really comfortable when the energy is absorbed into the body just now! Try again, see if you can feel the existence of energy this time, Alan closed his eyes again, because of the experience just now, he soon entered the state of emptiness, this time the energy Alan felt was no longer red energy, but colorful, with red light, blue light, yellow light, and even black, weird and mysterious.

Alan finally knew what was going on with the different attributes of energy mentioned in "Fighting to Win the Duel", the energy between heaven and earth was divided into many kinds, the red one should be the energy of the fire attribute, the blue one should be the energy of the water attribute, the yellow one should be the energy of the earth attribute, and the black one should be the mysterious dark attribute energy.

However, the god of war said that there are conflicts between some of the energies of different attributes, and under normal circumstances, a cultivator cannot absorb the energy of different attributes at the same time, otherwise they will interfere with each other, and it is a trivial matter to affect the speed of cultivation, and the most terrible thing is that if the cultivator goes mad, it will be too late to regret it.

However, there are also situations that complement each other, such as the energy of the fire attribute and the energy of the wind attribute can be absorbed at the same time, and the two have complementary effects, but there is generally only one kind of energy that fits the cultivator himself.

Generally speaking, when a beginner first enters the state of emptiness, the darker the color, the more consistent the energy of that attribute will be with himself, and the level he can reach in the future may be higher, of course, it is only a willingness to be, if a person with a high degree of congenital compatibility with energy does not work hard, then he will not have too high achievements.

At this moment, the two darkest colors that Allen saw were red and black, that is, the energy of the fire attribute and the dark attribute. The dark attribute is a very special attribute, except for the conflict with the mysterious light attribute, it does not conflict with any of the other attribute energy.

Eren tried to absorb the red light in the air into his body, and the red energy was very obedient, pouring into Eren's body like a spring. Allen's body was like a bottomless pit, greedily devouring the energy pouring in, and the wonderful feeling of being filled made Eren feel very comfortable.

Looking at the mysterious black energy on the side, Alan suddenly had an idea, can we absorb it together? Thinking of this, Alan separated a thought, attracted a trace of black energy, and then absorbed it into his body, and the black energy had a cold feeling after entering the body. The red energy and the black energy are distinct, and they are entangled with each other, rushing in Allen's meridians, and finally merging into the inner mansion, and the two energies each occupy a place, and then begin to grow continuously.

As time passed, Alan gradually noticed that the speed of the flow of the two energies slowed down, and at last it slowly stopped. At this moment, in Allen's inner mansion, two energies have converged into two balls of light, the red warm and scorching, and the black mysterious and cold.

Do they seem to be saturated? Then the next step is to compress them. According to the "Fight to Win the Duel", the energy in the air is absorbed into the body, and after it reaches a saturated state, it is necessary to start compressing it, and then the space is free, and it is absorbed at the same time, and so on. In the initial stage, the higher the degree of compression of the energy absorbed into the body, the greater the density, and the greater the possibility of impacting the higher realms in the future
