Leaving the downtown library, the Force heads straight back to the cold storage where the monster corpses are stored.

The temperature in the cold storage was maintained at around freezing, and the Force couldn't help but shiver after entering.

The room was dimly lit, and the Force fumbled to stop the refrigeration gate, and opened the overhead movable skylight, shining in bright light, and the temperature slowly rose.

In a space of less than ten square meters, four demon beast corpses of different sizes were placed in it, which looked cramped and crowded.

He closed the door with his backhand, rolled up his sleeves and began to carry.

Soon, he piled the other three demon beast corpses aside, and only placed one demon beast corpse in the middle of the room, which was the corpse of a soldier-level first-order dog demon beast.

He found the most comfortable position in a corner and sat down, silently adjusting his state.

After a while.

I feel that my mental and physical condition is excellent.

With a thought in his mind, the "gathering" ability of the Upanishads was officially triggered for the first time.

It was as if an illusory light shot out from the center of his eyebrows, shining on the corpse of the dog demon beast in it.

His "gaze" instantly penetrated the flesh and skin of his body, and fed back into his heart with a strange image.

Its body, its fur, internal organs, and bones were all transparent and blurred, and he could only see the light scattered throughout its corpse.

This is the Upanisham factor. When he saw this, he naturally realized something in his heart.

The points of light in the depths of its body remained largely stationary, while those on the outside of the edge slowly flowed into the outer void.

Again, he knew in his heart.

"Although the corpse of the demon beast can be stored for a longer time under refrigeration, as the arcane factor continues to pass, its level will still slowly decline. ”

However, this is not too fast in the refrigerated state.

Not only can he "see" the Upanishads, but he can feel the power of his "gaze" itself.

As soon as his mind moved, the mystical factor that was slowly dissipating stopped.

The mind moved again, and the mystical factors in the body of the dog demon beast began to concentrate in one place.

Eventually, all the points of light around the corpse of the dog demon beast disappeared, and all of them gathered at its heart.

In reality, as those points of light disappeared, its shell instantly collapsed, and only a faint amount of ash fell.

It seems that it is not just the passage of the Upanishads factor, but all the "forces" that maintain its existence are gone in that instant.

There is only one heart, suspended from the ground, remaining in its original position, untouched, unaffected by the disappearance of the rest of the body.

And in the Force's "field of vision", it was a heart-shaped light source that shimmered with an even richer brilliance.

"It's not enough. With this in mind, he controlled the Upanishads to continue to concentrate on the tip of his heart.

He now knew that there were two ways for a secret refiner to refine a secret refiner.

The first, and most common and universal, is that the esoteric cultivator gathers and guides the mystical factors in one place through the mastery of different "secret patterns", and through the "secret patterns" its state is constant and stable.

When the blood is refined, the blood automatically spreads, and the mysterious structure that appears on the surface of the secret refiner is like a meridian, which is the "secret pattern", or part of the "secret pattern", because the division of the secret pattern is not only on the surface of the secret refinery, but also penetrates deep into its interior.

"Secret pattern" is not one, but many, many kinds, with different functions, different abilities, has long developed a profound and mysterious system, the main daily life of the secret refiner is to learn and use the secret pattern, and then discover new secret patterns.

This is the growth method of ordinary secret refiners, and their mastery and application of secret pattern knowledge directly determine the upper limit of the level and quality of the secret refining items they can make.

In addition to this, there is a second method.

Ninety percent of the three books that the Force has carefully read are devoted to the first method, and the second method is only mentioned in a few sentences at most, without any additional explanation.

There is really no need to make additional explanations.

In one sentence, it is summed up, "perfect and natural".

Perfect-quality secret refining is not refined by a secret refiner, but when the concentration of the arcane factors converges reaches a certain critical point, it will spontaneously form various mystical patterns.

This pattern is the secret pattern, and it is the most natural and authentic secret pattern.

There is even a saying that this is the origin of the secret pattern.

If he took the formal path, it was impossible for the Force to become a secret refiner by just reading three secret refiner introductory enlightenment books, not to mention whether he had the talent for this aspect or not, he had not even mastered a "secret pattern".

Moreover, each of the secret patterns is extremely precious and impossible to find in the library.

Fortunately, although he has never mastered any kind of secret pattern, or even has no talent in this area at all, he has a more heaven-defying ability!

What he wants to do now is to concentrate and concentrate the Upanishads as much as possible.

When its concentration reaches a critical point, he doesn't understand the secret pattern, and the secret pattern will come to understand him.

At this time, he finally felt the difficulty.

If concentrating the sparse arcane factors that spread around the body of the dog demon beast to its heart before was like pinching a loose cotton ball into a ball, then what he had to do now was to further compress it on the basis of the already tightly crumpled one.

He clearly felt that all kinds of energy in his body were like floods that opened the floodgates, and the illusory light between the center of his eyebrows and the heart of the dog demon beast was flowing rapidly.

First the mystical factor in his own body, then his physical strength, and finally, his spirit.

It turns out that there is also a cost to using the "Gathering" ability, and the cost is far more than using "Insight" to terror.

Such an realization arose in his heart.

Just as the mystical factors accumulated in his body were exhausted, his physical strength was almost drained, and his spirit also felt extremely weak and trance, and he was considering whether to interrupt, this terrifying sense of passing quickly stopped.

"It's ...... Okay?"

At this moment, in his "field of vision", the Upanisham factor condensed again, and only one-third of the original entire heart was concentrated in the apical part of the heart.

The scattered points of light that resemble stars converge into one, like a heart-shaped gem, and together they radiate outward.

In addition, all the mystical factors are concentrated and condensed, but they are not evenly distributed, and naturally produce a certain vein pattern, like the natural texture of a rock or tree in nature.

"This is the perfect quality secret refining, this is the naturally generated secret pattern!"

Enlightenment naturally arose in the Force's heart.

He revoked his "Gathering" ability, the illusory beam of light shot from his eyebrows vanished, and his eyes saw the real world again.

Suspended a few feet in the air, more than two-thirds of the heart of the dog demon beast turned into embers and fell again, leaving only the tip of the heart as if it had lost its support in an instant and fell to the ground.

The Force reached out and grabbed it, holding it in the palm of his hand, and there was a feeling of warmth like jade.

Although it is the tip of the heart of the dog demon beast, it does not have a sense of flesh, and the color is bright blood red, like a strange gem.

Judging from the appearance alone, it far surpassed the few secret refining items that the Command Bureau provided to the students for free before, and I didn't think it was anything at first, but now when compared with the things in the palm of my hand, it seems too rough.

Compared with the seven inferior goods that Meng Xiaoxiao specially collected from Zhang Wei, it is even more incomparable.

"It's no wonder that some people would inflate the price of a perfect quality secret refiner. ”

Thinking of Uncle Yang's resentment before, the Force had an extra layer of clarity in his heart.

"In my case, I want to stock up more. ”
