Is your brain so full of muscles that it clogs your mind?

Wrong!

It should be that your muscles are full of brains - you are a smart and brainy body, you know how to comprehend yourself, make progress silently, lurk on weekdays, and when it comes to critical moments, you will take the initiative to come forward!

Hiss –

Terrifying!

Half a month later, the Force temporarily resided in the cave.

The corpse of a one-horned gray rhino demon beast with a body of four or five meters long and weighing more than a ton was lying on the ground.

The closed stone **, only a ray of sky light shines in, the Force is sitting in a corner, and a beam of illusory light in the center of the eyebrows shoots into the body of the one-horned gray rhinoceros.

Within his special vision, the mystical factors in the one-horned gray rhinoceros had all converged on his skin, but the Force had not stopped, further compressing it, and compressing it again!

Finally, under the condition that the mystical factor remains covered by the skin around the one-horned gray rhinoceros, it is condensed to the extent that it is as thin as paper, and finally reaches the critical point of metamorphosis.

Originally, it was just a dense stack of mystical factors with mysterious lines, and it took the initiative to stabilize and perpetuate the mystical factors that were concentrated to such an extent.

Eventually, when he opened his eyes and looked at it, the body of the one-horned gray rhinoceros was long gone, not even a remnant, except for some ember remnants, which were a strange object as thin as paper cicada wings and as flexible as silk.

This is a perfect quality secret made from the skin around the one-horned gray rhinoceros!

And on the side of this stone cave, there are already three perfect quality secret refiners made based on the skin of demon beasts!

They are the fourth-order, fifth-order, and sixth-order quality of black iron.

And now this one is the last one he tried.

When he collected his ability and put away the newly refined secret refining, he was already extremely weak, and he had been hollowed out from the inside out, from the body to the spirit.

"Even if it is a secret refining object of the same level and quality, the difficulty of refining is very different!"

The easiest, is based on the bones or parts of the demon beast such as the horns of the minions, etc., they are inherently easier to maintain a stable form of the arcane factor, and the degree of fault tolerance is higher, even if there is a mistake in drawing the secret pattern, it will not collapse immediately, there is a delay time, so that people can take more measures to remedy it, or simply remedy it by downgrading the level and quality, and retreat to the second, at least it will not be lost.

If it is based on the flesh and blood of the demon beast, the difficulty will be greatly increased, and if there is a mistake in the refining process, it will be extremely difficult to remedy, and the probability of complete collapse will be greatly increased, and it is difficult to save the capital by downgrading the level and quality, and there is a greater possibility of losing the capital.

This is also the reason why most of the secret refining items sold on the market are bones, minions, horns, etc., and those based on flesh, flesh, and internal organs rarely appear, but once they appear, they are mostly high-quality products.

The most difficult ones are those secret refiners that have a tendency to "hunt for curiosity" and "customize", and are targeted to meet certain special needs.

The Force's secret refinement based on the skin around the one-horned gray rhinoceros belongs to this category.

"One-horned Gray Rhinoceros's Skin: Black Iron Seventh-Order Secret Refining (Mystery Factor Content 7.8/10,000)

Quality: Perfect

Basic traits: Strength +8, Constitution +11, Speed +3

Bloodline Characteristics: [Sacrifice Collision]: When the one-horned gray rhino is faced with an invincible enemy, it will sacrifice itself to collide, and in this collision, the strength, physique, and speed of its body are all fused into one, and the output is the greatest damage.

Talent trait: [Hard Skin]: The skin is like a solid rock, and the defense is doubled. ”

"There are actually two special characteristics!"

The Force was a little surprised, the perfect quality of the secret refiner, the strength and body speed of each small level +3, the total bonus of the seventh order of black iron is 22, this is nothing to say, but the direct contribution of two characteristics is a little surprising to him.

However, after thinking about it carefully, it seems reasonable, even if it is a secret refining object of the same level of perfect quality, there are difficulties in refining, and the difficulty of refining based on the complete skin of the one-horned gray rhinoceros is far greater than that based on the horns of the bones, so the reward of feedback will naturally be greater, otherwise why would someone deliberately give up the easy and difficult, it can't be simply to challenge the high difficulty!

This is the most suitable secret refining thing he can refine now, and after looking at it for a while, the Force directly cut his finger with a knife, smeared blood on this secret refining, and began blood refining.

Soon, this secret refiner turned into pure energy and merged with his body, and this time, this energy did not drill into his body, but spread instantly, covering his entire body, quickly merging with his own skin, and then quickly hiding and falling silent.

He felt as if he was wearing a strange, intangible, qualitative, and even somewhat ill-fitting "dress".

The esoteric refiner self-detonates in the body, causing permanent damage that destroys a matching position of the self, and only a perfect quality refiner can bypass this damage, so if this is the case, it is feasible for the Force to refine a perfect quality refiner at will...... It's not hard for him to obtain.

However, to be on the safe side, he chose the one that suited him best.

Through the force of the "Rigid Realm Chapter", it is known that every time the six refining of the Rigid Realm is completed, its body will show a greatly increased tolerance to the corresponding class of secret refiners, and if it is the corresponding secret refining of blood refining, the rejection reaction will be significantly weakened, and the digestion efficiency will be significantly enhanced.

In the general talent test, the matching bit is only related to the quantity, and has little to do with the position, for example, a person's matching bit is three, which means that the secret refining that can be refined is three, as for what kind of secret refining is it, there are no special requirements, even if the three are bones, it is not a big problem, just pay attention to not the same part, for example, it is easy to cause some because it is too "crowded" And the disorder caused, and this is well avoided, more than 200 bones in the human body, which means that there are more than 200 options, and you can bypass it with a little attention.

However, there are also some related to specific positions in the body, which is considered a "special type" in the talent test, and the Force has only heard of it, but has never seen it, but I didn't expect that I could actually become this kind of "rare breed" through cultivation.

That being the case, he put a double insurance on himself.

It's both perfect quality and skin type.

Sure enough, the blood refining was successful.

Moreover, the rejection reaction was lighter than he had imagined, and it was even easier than the first blood refining of the Black Iron Third-Order Secret Refinery.

He had just completed the blood refining, and he was still the perfect quality of the seventh order of black iron, and his strength had made an obvious small leap.

The Force moved around the cavern and quickly regained his grip and adjusted to his current physical state.

"Next, it's going to be a bit of grinding. ”

At least, it's not suitable for too much tossing before going step by step and honestly completing the Gang Realm meat refining.

One piece and one relaxation is the right way.
