In a dark room underground, the space of the darkroom is very large, and it is surrounded by hard volcanic rocks, these rocks, scorched and solidified by the magma in the center of the earth, are not inferior in hardness compared to ordinary mortal-level high-level crystals.

However, these volcanic rocks are too hot all day long and have too many impurities to be used for crystal refining. Moreover, once these rocks are soaked in water, they are like encountering nemesis, and they will easily turn into white dust.

This is also why those people who rely on the Ancient Dragon Clan to peep into the Martial Realm can dig out such a cultivation room. This cultivation room went deep into the underground of Sanfu City, and the temperature was extremely high, even with a trace of fire poison.

But this kind of temperature is a treasure land for people who enhance their physique and cultivate fire attribute exercises. This is a cultivation room specially built by Gu Yan for himself, and this cultivation room is equipped with formations outside it, and ordinary people cannot enter it.

But with the exception of the dancer, the token Gu Yan, who controlled the formation of the cultivation room, was only handed over to the dancer alone. At this time, in the cultivation room, the eight stone lamps were all inlaid with a fist-sized night pearl, so even though it was more than a thousand meters underground, this cultivation room was still bright.

At this time, on a square stone platform in the cultivation room, a jasper-colored tuanpu exuded a bone-chilling chill, forming a huge contrast with the scorching aura in the entire environment.

On top of the jade group, Gu Yan has been meditating and practicing here all night, and the scorching qi in the cultivation room has a very obvious effect on Gu Yan's "Great Five Elements Formula", and the ancient rock on the group is like a burning fire in the heart, and the whole body exudes a scorching breath to resist the cold air emitted by the jade group.

According to Gu Yan's guess, the material of this jade tuanpu should be a thousand-year-old cold ice jade, otherwise it would not have such a miraculous effect.

Gu Yan in meditation was in the two heavens of ice and fire, but he was very happy, because Gu Yan could clearly feel that his physical strength was gradually increasing, although it was a little uncomfortable, but compared with the benefits it brought, Gu Yan would rather this kind of training be more intense.

"The cultivation here is really a source of infinite benefits, the magma in the center of the earth, and the rich vitality of heaven and earth. Gu Yan opened his eyes and sighed with satisfaction.

Immediately, Gu Yan closed his eyes again, thinking back to his Red Demon Burning Sky Claw's moves, and for this self-created combat skill, Gu Yan had a special feeling.

But for Gu Yan, although he created this powerful combat technique by chance, but in the final analysis, chance occupies most of it. Moreover, this combat skill also lacks the essence of advanced combat skills.

However, this is not to blame Gu Yan, after all, Gu Yan is just a Martial Yuan Realm kid, since ancient times, martial artists of the Martial Yuan Realm have created their own combat skills, and there are very few people whose power can reach the Red Demon Burning Sky Claw, not to mention that the combat skills created have the essence of high-level combat skills.

High-level combat skills, which one did not come out after its creator pondered and pondered, plus improved and improved over and over again. The more advanced the combat technique, the richer the essence of the combat skill it contains, and the more it allows the cultivator to exert its essence and great power.

Gu Yan thought about the Red Demon Burning Claw again, and Gu Yan decided to divide it into three types: the Burst Claw, the Void Claw, and the Soul Claw. Although it seems very simple, in Gu Yan's view, it can also be said that it is a summary of many advanced combat skills, and the quality of combat skills is not necessarily related to the number and complexity of moves.

For example, the supreme combat skill of the demon clan - "Overlord Nine Styles", each style seems simple, and there are only nine moves before and after, but the power is terrifying. Even if it is the first form, Gu Yan has only seen and comprehended a trace of it so far.

After secretly sitting down and deciding in his heart, Gu Yan got up, took off the robe on his body, jumped in shape, and landed in front of the cultivation stone platform, with his two hands exerting force, his fingers tightening, and there was a fierce claw force between his five fingers.

According to the tips for cultivating combat skills in the ancient inheritance, if you want to practice claw skills, you must first practice claw shape, from the outside to the inside, the claw shape and the inside, and the strength from the form.

Gu Yan's Red Demon Burning Claw is an extremely domineering combat skill, which requires extremely domineering claw power to control, and the more domineering the claw power, the more it can exert the essence and power of the Red Demon Burning Claw.

Gu Yan's five fingers were like steel claws made of five magma poured, Gu Yan's eyes were cold, and his five fingers went towards the crimson volcanic rock wall claws in front of him.

"Ahh

Five fingers clawed deeply into the volcanic rock, Gu Yan's face instantly became extremely painful, Gu Yan's two fingers had oozed blood, but this was not the reason why Gu Yan was so painful.

You must know that under the volcanic rock wall is the core magma that is hot enough to smelt the king-level refining materials, and the temperature is as high as you can imagine. Gu Yan's physique was not at the same level as the demon body of Ghost Ku and others, although the temperature could not fuse Gu Yan's fingers, but the violent burns were enough to make him suffer inhuman pain.

As the saying goes, ten fingers connect the heart, and the pain can be imagined, but Gu Yan slightly restrained the painful expression on his face, but the ten fingers did not flinch in the slightest.

Being able to endure hardships and hardships is a master, Gu Yan knew that his claw shape could not reach the essence and true power of the Red Demon Burning Sky Claw at all.

In this way, Gu Yan stretched out like this, and then grabbed it fiercely, and after cultivating for nearly an hour, a pair of hands that could be called delicate as a woman were now covered with bloodshots, and a thick layer of fire cocoons produced by scorching heat appeared.

At this time, Gu Yan did not stop, he wanted to take advantage of this cultivation momentum and work hard to cultivate the Red Demon Burning Sky Claw. The body jumped, practicing the Bursting Claw move over and over again, and the object of Gu Yan's sparring was still the volcanic rock wall that was already covered with finger holes and claw marks.

"Burst claw, one claw splits the world!"

Gu Yan let out a loud shout and made a red paw print towards the volcanic rock wall in front of him, and in an instant, the volcanic rock wall emitted a violent turbulence, and pieces of volcanic rock debris kept rolling down.

You must know that this cultivation room is thousands of meters below the ground, and the extremely high temperature and huge pressure are enough to make this volcanic rock a huge whole, but it was grabbed by this claw of the ancient rock, a ravine more than ten feet deep, and a pile of volcanic stones rolled down.

A smile appeared on Gu Yan's face, "It is worthy of the combat skill created by Ben Shao himself, and it is so powerful." "Gu Yan is indeed very satisfied with the power of this Bursting Claw, after all, this is a combat skill created by himself, and it is really gratifying to have such power.

At this time, Gu Yan was not in a hurry to cultivate the second type of Void Claw, the Void Claw consumed a lot of True Yuan, and more importantly, cultivating the Void Claw required a special environment, obviously this underground cultivation room was not very suitable for cultivating the Void Claw.

However, Gu Yan couldn't be idle, because the highlight of his cultivation today was the first form of "Overlord Nine Styles" - explosive killing. Explosive killing, what is particular about is a kind of explosive power, the power of one hand, enough to exert a thousand momentum, compress to the extreme, and explode to the extreme.

Cultivating explosive killing requires a certain physical foundation, and without a strong physique, it is completely impossible to carry the power needed to perform explosive killing. Fortunately, Gu Yan's "Demon God Transformation" did not practice in vain, and it just met the physical conditions for cultivating explosive killing.

Explosive killing, mainly relying on the power of the palm, is enough to break mountains and rivers and break the void. At the same time, blasting is a very offensive killing skill, and to practice blasting, you must achieve oneness in your heart and figure it out, otherwise you will not only be unable to exert the power of blasting, but will be counterattacked by combat skills.

According to the original concept of the Demon Ancestor, combat skills, the so-called war, should do their best, and the so-called skills refer to killing skills. Only with such a belief can we truly understand what is the real domineering and what is the king of combat skills.

Silently comprehending the essence of explosive killing again, after Gu Yan drank a pot of monkey wine in one go, he jumped and began to practice explosive killing.

The explosion is divided into nine forms, all in the hand, borrowing the palm to condense the knife, borrowing the palm to exert force, so as to achieve the palm through the whole body, and burst out of the ultimate of its own strength. Each style is very mysterious, and it can be said that the essence of thousands of palm techniques is summarized in it.

Gu Yan's hand shape is constantly changing in the air, and each style seems to tear out a fierce palm power, and to perform each style, you need to take the power of the whole body as the center of the palm, gather a little, form a palm, and cover it to burst out with the power of ten thousand jun.

Gradually, Gu Yan became more and more immersed in the comprehension of explosive killing, and the so-called real supreme combat skills were bound to focus on their meaning and comprehension, rather than just sticking to one move and one style.

If the cultivation of combat skills reaches the realm of natural unity, you can completely ignore the flaws in the moves, and your mind will move, and the momentum will be natural, which will be the strongest combat skill and the highest comprehension.

Although Gu Yan's cultivation and explosion killing was comprehended from the explanation of the Demon Ancestor, many of which summarized the essence of the "Overlord Nine Styles", but for Gu Yan itself, everyone's cultivation path is different, and no matter how subtle other people's comprehension is, it is just a direction for their own cultivation.

It is absolutely impossible to become the key to your comprehension of its essence, the essence of combat skills, not only by imitation and learning can be understood, the best way is to fight, only combat can become the key to constantly accumulating experience and combat skills comprehension.

Therefore, when Gu Yan checked the cultivation moves and essence summary of the explosion in the sea of knowledge for the last time, he had already decided not to follow the understanding of the Demon Ancestor.

At this time, Gu Yan's eyes lit up, his figure jumped up from the spot, and shouted, "Explosive first form, inch palm." ”

The palm of his hand bent, and he leaned on his knuckles towards the air, and a sharp palm force slammed into the volcanic rock wall. Immediately after the second form, the third form······

In each form, Gu Yan's hand changed rapidly, and the palm strength became more and more fierce, domineering, and the power brought out became more and more terrifying, and the rock wall at this time was already hideous.
