The Force felt his state carefully, and then looked at the other three demon beast corpses piled on one side.

The consumption is much greater than expected.

He sat there and recovered for a while, then got up and closed the movable skylight above the cold storage again, and the room became dark again.

Then reopen the refrigeration valve, pick up the army-green bag that was placed here yesterday, and lock the door of the cold storage with his backhand.

I went to the office and paid 600 yuan again, and it was renewed for three days.

Nearly a thousand of the "huge sum" that has only been in hand for one day has been spent, and the Force is also in a staggering heart.

In the past, this was enough for him to be comfortable for three or four months.

"As long as it involves cultivation, the cost will go up. ”

This is just the simplest way to preserve a few demon beast corpses.

Big money is spent, and small money is even less cared about.

He didn't have the heart to cook at all, so he went directly to a nearby lo-mei restaurant before going home, spent 20 yuan on a greasy meal, and then purchased some cooked food.

When I get home, I wash up a little, and I don't care what time it is, and I just fall asleep.

When I woke up, it was dark, and there was occasional movement, which made the world even quieter.

The Force opened its eyes and lay still.

It was a long time before he sat up and lit a lamp on the bedside table, next to a desk with a thick stack of books.

Because no one has been patronized for a long time, there is already a thin layer of dust on the tabletop that was originally rubbed by his sleeve.

He took out a random book and flipped through it, the various underlines that indicated different levels of emphasis, the notes, the things that were scribbled and scribbled when he was wandering away, those creases, seeing these, he could even recall the situation at that time, what kind of thoughts he had at the moment when he left these traces.

For the first time, he realized that his memory was so good.

Why can't I perform in the exam?

After flipping through the pages for a while, he chuckled meaninglessly, threw the book back on the desk, and the inexplicably depressed mood just now unexpectedly fully recovered.

He took out the secret refining condensed from the tip of the heart of the dog demon beast from his arms, and used his naked eye, "collection", and "insight...... Look at it in every way you can.

To the naked eye, it looks like a strange and besmering gem.

Illuminated by the illusory light emitted by the "Gathering" ability, he could see the mysterious patterns formed by the convergence of the arcane factors.

And after using Insight, it was some information that poured into his mind.

After digesting this information, he knew the secret artifact in detail.

The first order of black iron, the quality is perfect, there is an additional bonus to strength and agility, and there is a special ability, at the cost of rapid consumption of physical strength, the heart pumps rapidly, the strength is fully exploded, and the price is that when the physical strength is exhausted, there will be a long period of weakness.

After obtaining this information, the Force had another thought in his mind.

"The 'Insight' ability can not only see living beings, but also the secret refiners, and I want to collect more information about different types of secret refiners, so that the information obtained through 'Insight' will be more accurate. ”

The information he was getting now lacked a precise quantitative description.

Eventually, he began to carefully observe the structure of the Secret Pattern.

"For a perfect quality refiner, there are actually two parts that make up its value, the first is its perfect quality, and the second is the naturally generated secret pattern structure in it.

If it is a rare or even unprecedented secret pattern, even if the level of the secret refiner itself is not high, its value is still incalculable.

It's no wonder that those who have the ability to collect perfect-quality secret refining objects choose to hoard them instead of using them, and directly refining them with blood is the real tyrannical artifact. ”

"A powerful force has many foundations, a steady stream of access to resources, mobilizable forces, the cultivation of reserve forces, and all kinds of knowledge and secrets related to cultivation...... But there is no doubt that no matter what method is used, the secret pattern must be at the forefront. Even with some unique secret patterns, a power can flourish. ”

The Secret Pattern is precious and difficult to obtain.

The pupil of the mystery gives him the ability to make secret patterns in batches!

Even though his understanding of the cultivation world and the world was extremely poor, he still understood what a terrifying thing this was.

"Who the hell were you, old man. ”

Gradually, as he went deeper and deeper into "watching", all kinds of distracting thoughts naturally disappeared, and in his eyes and hearts, there were only secret patterns.

Under his special vision, he can see clearly both inside and outside, which is another great advantage for him, even if others have the opportunity to come into contact with the perfect quality of the secret object, it is impossible to "see through it at a glance".

The book says that different secret patterns have a common basic structure, following a common set of rules, and the basic structure is presented by different combinations. ”

Before you know it, it's daylight outside the window.

The Force also confirmed one thing.

"It seems so complicated, but I didn't expect it to be composed of four basic structures that have been repeatedly combined and transformed. ”

He rubbed his brow, thinking to himself.

In the case of only borrowing the special vision of the "gathering" ability, without mobilizing the arcane factor, the consumption is very small, but it is still a little tired after lasting so long.

He didn't continue watching, and went straight out when he was fully restored.

Came to the cold storage where the corpse of the demon beast was stored again, and this time in the middle of the room was a second-order demon beast of the military level, a demon beast in the shape of an enlarged version of the gray rabbit.

"Compared with yesterday, the Upanishads factor has been lost again, and if it continues for a few more days, it will be downgraded. He thought to himself.

The previous steps were the same as yesterday, the illusory light in the center of the eyebrows shot out, and the arcane factors around the rabbit-shaped demon beast converged towards its heart.

The only difference is that there are more mystical factors in the body of the rabbit-type demon beast, and it costs more to "knead" them together.

When all the mystical factors converge in the heart, he wants to go further, but he feels a little unsustainable.

He also does not force it, but manipulates some of the mystical factors to move according to a special trajectory, and repeats itself.

This trajectory is the four basic structures that he has repeatedly observed and confirmed to have been imprinted in his mind, and they are arranged in a special way to form a whole.

When some of the arcane factors moved and circulated along this trajectory repeatedly, a special scene appeared.

It's like a magnet in a pile of iron filings.

More and more mystical factors are added, and they also flow with the movement.

When more and more mystical factors are "pulled in", the trajectory that has become crowded spontaneously splits, one becomes two, as if copying.

As a result, more and more Upanishads are joined.

Two becomes four, and four becomes eight......

Eventually, all the mystical factors are included.

Stable forming.

He withdrew his ability, and the rest of the demon beast's corpse had turned into embers and fell, and a heart-shaped secret refining object fell into his palm.

Just to the naked eye, it is much inferior to yesterday's one.

"The color is uneven, not condensed enough, and it looks bloated, which means that there is still a lot of room for improvement and optimization, but since it has indeed become, it is undoubtedly a second-order black iron secret refiner, which means that it is correct in the general direction, otherwise there will be no secret refining at all, and it will completely collapse at the moment when the arcane factor is not running smoothly, and nothing can be gained. ”

The next day, the Force harvested another Black Iron Third-Order Heart-Type Secret Refinary.

Although the lesson of the last time has been learned and the basic structure of the secret pattern has been adjusted and optimized, the mystical factors of the soldier-level third-order demon beast body are more, and the Force feels more and more "heavy", and the final product is still unsatisfactory.

On the last day, the Force once again harvested a Black Iron Fourth-Order Heart-Type Secret Refinary.

He really felt his own limit, and the arcane factors in the demon beast's body only converged on the area of its chest and internal organs, and it was completely "pinched".

In the end, he gritted his teeth and gathered and pinched the mysteries little by little with the secret pattern structure that had been further adjusted, optimized, and perfected.

When he took this Black Iron Fourth-Order Heart-shaped Secret Refining into his arms, his head was already painful like a pinprick in a pinprick.

If it weren't for the fact that this soldier-level fourth-order demon beast had consumed too much combat merit, he would have wanted to give up a few times halfway.

"This time it's really to the limit, if a soldier-level fifth-order demon beast is placed in front of me, no matter how hard I grit my teeth and insist, it's useless. ”

In addition, he has another experience.

"Unless it can be refined into a perfect quality of the secret refining in one step, it is stupid to forcibly 'pinch' it with the ability, which is not only inefficient, but also more energy-consuming, if it is used as an invisible brush, draw the trajectory of the secret pattern, refine the secret refining through the natural affinity of the secret pattern to the arcane factor, and then appropriately increase the concentration of the arcane factor, so that it will not be lost in the refining process, and the result will be twice the result with half the effort. ”

Others want to become a secret refiner, it's like climbing a mountain, and even the path up the mountain is not very clear, and it is unknown whether they can get through it or how far they can climb.

And he is completely reversed, if you really want to say any difficulty, probably only due to the limitation of his own strength, the higher level of the secret refining can not be refined for the time being.

One of the things he has done most often since he got the "plug-in" is to hold himself down hard and desperately.

"You can't be proud, you can't float, there is probably a big trap behind the big pie!" he told himself.

......

Before leaving, the Force connected a water pipe outside, rinsed some of the residual dust embers in the cold storage, and the black and turbid sewage was discharged along the ground culvert, and the skylight and cold storage door were opened to allow air circulation without any odor remaining.

As for how to explain that something in cold storage is missing - it doesn't need to be explained at all.

Except for the Liu Changfu brothers, no one knew what they had put inside. And the staff here is subordinate to the internal establishment of the Civil Affairs Bureau, because it needs to be guarded 24 hours a day, not only three shifts of people rotate, but also the smell of the agency is strong, as long as there is nothing wrong with their own affairs during work, no one will take care of the side affairs - don't worry about that.

So, all you need to do is return the key before the time is up, and the matter is over.

As for the extra cleaning I did, I can only say that I am worthy of being an intellectual, and I am meticulous in doing things.
