At this moment, Elder Song Yan seemed to be aware of the strange thoughts that appeared in Sun Wukong's heart, so after adjusting his standing posture, he raised his hand to Sun Wukong below, and explained in a low voice: "Apprentice, you must remember that every body protection spirit weapon contains extremely strong power, it depends on how you develop it, if you develop it well, it will become a stepping stone on your way forward, but if it is not developed well, it is estimated that it will also become a roadblock on your road to repair." ”

After seeing that Sun Wukong's expression gradually changed a little because of his words, Elder Song Yan smiled indifferently and softened, and then turned his gaze to the solid brick layer in front of him again.

Previously, although he had used the power of the special spirit weapon to cause a certain impact on the surrounding bricks, he did not cause the brick next to him to cover the ventilation eye to suffer the slightest damage.

This was really a bit out of Elder Song Yan's expectations, so much so that after he noticed this wonderful change, the smugness on his cheeks was gradually replaced by a faint doubt.

When he used his mind to draw out a sufficiently strong attribute aura and infused it all into the inside of the Shaking Mountain Drill, Elder Song Yan glanced at the bricks in front of him contemptuously, and teased in a low voice: "You guy is quite hard, I didn't expect that the surrounding bricks have been affected to a greater or lesser extent, but you have not been affected at all, I want to see what you are doing." ”

As soon as the words fell, Elder Song Yan's palm that clenched the Shaking Mountain Drill was under the control of his mind, carrying an extremely strong impact force, and rushed straight towards the position of the surface of the brick.

This time, the force exerted on the Rock Drill was twice as strong as before, so that before the whirlwind halo of the drill bit touched the bricks, layers of fine stone chips appeared abruptly with spiral impact scars, and under the traction of the halo rotation force, they floated into the surrounding void and lingered in the direction of its rotation for a long time.

I thought that the area in front of him would shatter under such an impact, but to Elder Song Yan's expectation, the bricks distributed around the ventilation eye all presented a devastated picture because of this fierce impact, but the main brick that covered the ventilation eye was not affected in the slightest, but became smoother and cleaner because of the impact force.

"Eh, it's really hard enough, such a strong impact can't hurt you in the slightest, it seems that if I don't have to be serious, you really don't take me seriously." After he teased the main brick in his own words, Elder Song Yan slowly closed his eyes, and used his mind to separate about half of the spiritual energy in the Dantian Spirit Palace, so that it was all instilled into the Mountain Shaking Drill held in Elder Song Yan's hands.

Today, Elder Song Yan has completely aroused his interest by the brick in front of him.

You must know that the destructive power contained in the Mountain Shaking Drill itself is already fierce enough, and the one that appeared in Elder Song Yan's hands was a "Second Order Mountain Shaking Drill" that had been promoted to one level on the basis of its original.

Although the mountain-shaking drill has lost its impact bit at the tip, the drill bit replaced by the whirlwind halo can release more powerful impact power.

However, under the destruction of this impact, the main brick still stands like a pine and cypress in the wind, which proves that the materials used to make the main brick must be different.

Thinking of this, Elder Song Yan slowly withdrew the Mountain Shaking Drill that continued to attack, and then gently touched the surface of the main brick with his other free palm.

In an instant, an extremely strong fiery aura suddenly flowed out from inside the bricks, and quickly spread along Elder Song Yan's palm to his entire arm, causing his arm to instinctively retract at this moment.

Although the violent friction caused a blazing high temperature on the surface of the main brick when the Mountain Shaking Drill caused an impact on the main brick, this high temperature would not have much impact on Elder Song Yan of the Fire Cultivator.

But now Elder Song Yan felt another strange high temperature from the inside of this brick, which was derived from its interior and mixed with the friction temperature of the outer layer, which formed a violent heat that Elder Song Yan couldn't even accept, and this also made the doubts in Elder Song Yan's heart grow to a level that could not be attached.

It seems to be a little unbelievable what is happening in front of him, but now Elder Song Yan is covering the surface of his palm with the aura in order to be able to absorb the high temperature on the surface of the main brick with the help of the power of the aura, because only in this way can Elder Song Yan perceive it at the moment of its purity, and what is the origin of this brick, under this perception, Elder Song Yan can make a decision.

After the concentration of aura on the surface of his palm reached its highest, Elder Song Yan slowly covered it on the surface of the blazing bricks, but he could clearly see that the high temperature on the surface of the bricks, under the influence of this aura, turned into a thick red mist out of thin air, which was gradually absorbed by Elder Song Yan's palm and sent into the Dantian Spirit Palace for refining.

After the red mist was completely absorbed, the long-lost fiery aura suddenly flowed out from the inside of the brick, and collided with the temperature of the surface of Elder Song Yan's palm.

Although the collision was not manifested in the real environment, the vague breath that diffused from the contact position between the two made everyone present vaguely smell a faint "smell of gunpowder".

After about a dozen breaths, Elder Song Yan's palm was suddenly retracted, and the dark red burn that appeared in the palm of his palm was the most powerful answer to the doubts in Elder Song Yan's heart.

"I didn't expect it to be Nirvana, but why is this thing here? From the previous engraved inscriptions, I didn't notice that this Plague God of Wealth had anything to do with the Shadow Moon Sect. Why did there appear a rock belonging to the Qinglong Gate in his immortal ruins? After the doubts in his heart were churning, Elder Song Yan smiled bitterly in surprise, and then once again aimed the mountain-shaking drill in his hand at the main brick.

Nirvana is a unique rock of the Qinglong Gate, because it is in the blazing fire mountain all the year round, so under the passage of time, the fierce flames will remove all the impurities contained in its body.

What remains is only the extremely pure rock part, and it is precisely for this reason that its hardness has been multiplied on the original foundation.

According to rumors, the reason why Qinglongmen was able to sit firmly in the second position among the overlords of the five directions was due to Nirvana, in addition to its own spiritual strength.

After all, the entire sect of the Blue Dragon Sect was built using Nirvana, and not only that, but Nirvana could also release a violent high temperature on top of its hard foundation, attacking everyone who approached it.

With these two characteristics of Nirvana, the Shadow Moon Sect was able to remain invincible for a long time in the previous battles.

And this was the most fundamental reason why Elder Song Yan was able to immediately deduce its origin from just one rock.

"Now there is only one answer I can think of, Qinglongmen, you are really powerful enough, you can even find a place, but since Qinglongmen is here, why don't you take the things inside? Could it be that Qinglongmen has another purpose? Could this be related to the fake mission issued by the Futu Temple? After a strange thought flowed through his mind, Elder Song Yan sneered indifferently, and then sank into the process of impacting the main brick again.

After casually adjusting his disordered mind at the moment, Elder Song Yan smiled indifferently, and then turned the mountain-shaking drill he was holding tightly in his hand and slammed towards the Nirvana in front of him.

Although the main brick made of Nirvana was extremely hard, it was not impossible to use the second-order mountain-shaking drill in his hand to shatter it.

It's just that now that Elder Song Yan needs to infuse the spiritual energy into the Shaking Mountain Diamond, it can't be only a pitiful half, at least eight or nine out of ten spiritual energy in his body.

Because only in this way can the special effect of the aura be used to fully stimulate the power implied in the Mountain Shaking Diamond, and this is still based on the second order of the Mountain Shaking Diamond.

If it was an ordinary first-order mountain-shaking drill, even if all the spiritual energy in Elder Song Yan's body was infused, it might not be able to successfully shatter the Nirvana.

This is why the Qinglongmen was able to stand in the position of the overlord of the five directions for a long time only with the sect building made by Nirvana.

As the amount of spiritual energy reserves in Elder Song Yan's Dantian Spirit Palace continued to decrease, a layer of extremely fierce rotating wind breath suddenly appeared on the outside of the Mountain Shaking Drill that he was holding tightly in his hand.

In the blink of an eye, it fused perfectly with the rotating halo that had previously condensed at the tip of the drill body, making it a light drill bit the size of a small arm, and in an instant, it grew into a giant drill bit with a diameter of two feet.

Not only that, but in the perimeter of the drill bit, everyone could clearly see that layers of spiral-shaped red aura were floating up and down, like a small flame group accompanying him, full of mystery.

Seeing this, the smug smile on the corner of Elder Song Yan's mouth increased a few points again, and then he snorted softly in a low voice, and his palm no longer had the slightest hesitation, and hurriedly gathered his strength and slammed out the mountain shaking drill that he was holding tightly.
