"This should be the deepest part of the 'Rust Refining Demon Domain'. If Zhou Zhihao and the others can come here and resist the invasion of these iron particles, then they have enough strength to compete with the members of those four teams. However, in just one month, relying on their own cultivation alone, I'm afraid not many people will be able to reach it. Sun Yan thought silently.

The strength of the Yuan Force in his body now is comparable to that of the top martial arts masters, and if he wants to move freely in this basin, he needs at least a strong inner yuan comparable to ordinary martial arts masters.

Among the specially trained teammates, I am afraid that only Feng Yan, Meng Dongwang and Feng Lingxue can barely resist the invasion of iron trace particles here.

"It's just three people, that's not going to be able to compete with those four teams, at least double the number of people. It's a near-impossible task to achieve in a month......"

Standing in this basin, Sun Yan thought silently, and suddenly, a "rustling" sound came out, and he saw that not far ahead, a stream of iron trace particles actually gathered and slowly condensed into a huge body.

In a moment, strands of iron particles quickly condensed, and a huge rusty giant elephant appeared in front of him, with a rust-colored body, a large thick trunk, and two sharp rust-colored tusks.

[Rust Refining Demon]!

The body of this rusty demon elephant was tens of meters high, and its length was more than 30 meters, and the huge trunk of the elephant shook out, and even the space was swung out of cracks.

This kind of monster condensed by iron trace particles is actually made up of countless fragments of martial arts true intent, which is condensed from this, and has extremely terrifying destructive power.

"It's ...... , after the true meaning is channeled, is it the puppet of Yuan Energy created from this?"

Looking at this Rust Refining Demon Elephant, Sun Yan's expression was slightly solemn, there was no doubt that this [Rust Refining Demon Elephant] was specially created by Uncle Iron Spoon, and from this Demon Elephant, he could feel a threatening force.

"Is this what special cultivation is about? It's kind of interesting. ”

His shoulders sank slightly, Sun Yan slowly clenched his fists, and from the fluctuation of the power emitted by this [Rust Refining Demon Elephant], he could feel that the strength of this Demon Elephant was comparable to that of a top martial arts master, and it was an excellent actual combat opponent.

"This kind of Yuan Energy puppet, even if it is defeated by me, can be reborn. The special cultivation arranged by Uncle Iron Spoon is really suitable for me. Sun Yan thought secretly.

Around his body, a stream of Yuan Force poured out, quickly attaching to his whole body, and Sun Yan was ready to fight fiercely with this rusty refining demon elephant.

Whoosh whoosh ......

Suddenly, on the ground around him, rust-colored chains broke out of the ground, as fast as lightning, Sun Yan couldn't react at all, his hands, feet, waist and neck were all bound by a rust-colored chain.

"This is ......" Sun Yan was shocked, and immediately broke free, but found that no matter how much he urged the power, he couldn't shake these rust-colored chains in the slightest.

At this time, Uncle Ironspoon's voice sounded around: "Don't bother to break free, these six chains are injected with my true intentions, and with your current strength, you can't break free." ”

"Hehe, Ah Yan, do you think that the content of the special training is only to fight the [Rust Refining Demon Elephant]? Although such special training is effective, how can it be possible to make a leap in a short period of time?"

"If you want to promote the advancement of [Ninety-Nine to One Technique] in the shortest possible time, the best way is of course to be beaten. The destructive power of this [Rust Refining Demon Elephant] is amazing, Ah Yan, you see that I think more about you, so enjoy this month's special training......"

Immediately, Uncle Iron's voice slowly disappeared, and the rusty demon elephant not far away discovered Sun Yan's existence, and his rust-colored eyes lit up, letting out a low roar, stepping on the ground, and charging violently, hitting it straight over.

Knock knock knock...... , The ground trembled violently, and I saw this rusty demon elephant running with a bang, like a moving hill, and a huge elephant trunk flew in the air, crashing towards Sun Yan.

"Damn Uncle Iron Spoon, I know he's not well-intentioned. ”

Seeing this scene, Sun Yan couldn't help but change color, at this moment his whole body and limbs were restrained, and he couldn't dodge or counterattack at all, but only relied on his physical strength to resist the attack of the rust refining demon elephant.

"Humph!"

With a cold drink, the Yuan Force in Sun Yan's body was like a turbulent flow, running wildly, and the dense Yuan Force quickly covered the whole body, forming a layer of Yuan Force armor like a substance.

A trace of Fenggang circulated on this layer of Yuanjia, and then, above the Yuanjia, there was this turtle pattern emerging, Fenggang tortoise shell!

After returning to the Imperial Wind Academy, Sun Yan's entry into the [Ninety-Nine to One Technique] has made some progress, and when he runs this supreme defensive martial art, his defensive power can easily withstand the full bombardment of a tenth-level martial artist.

This is only the first stage of [Ninety-Nine to One Technique], that is, the stage of Zhengang refining tortoise shells, or in other words, the stage of Fenggang refining tortoise shells.

In this first stage, the power of the wind gang fused in the [Ninety-Nine to One Technique] was distributed on the surface of the Yuanli tortoise shell, and it could only carry out the most basic anti-shock power, and Sun Yan was not able to control these wind forces.

After all, these wind forces are foreign, absorbed from the wind gang in the storm prison, that is, they are foreign things, Sun Yan's Yuan Force cultivation at this time is also the beginning of the ninth-level martial realm, and it is difficult to control these wind gang powers.

Originally, according to Sun Yan's speculation, when he hit the tenth-level martial realm and truly became a martial arts master, he should be able to control these wind powers, and from this, the [Ninety-Nine to One Technique] would be able to go one step further and cultivate to the second stage of this supreme defensive martial art, the Wind Gang Turtle Pattern!

The hallmark of the second stage of this exercise is to control the Gang of True Intentions, and to draw the silk into patterns to form the turtle patterns of the Gang.

Gangzhi's tortoise pattern is the characteristic of the second stage of [Ninety-Nine to One Recipe].

Now, Uncle Iron Spoon's special cultivation method is actually to accelerate the formation of the Fenggang Turtle Pattern through the terrifying impact of external force, this method is undoubtedly extremely effective, but it is also extremely dangerous.

Roar......

This [Rust Refining Demon Elephant] roared, and the huge thick trunk was thrown over, wrapping Sun Yan's body, and the huge elephant trunk immediately tightened violently.

Squeak, squeak...... , The Fenggang tortoise shell around Sun Yan's body burst out with a dazzling light, and the power of Fenggang in it flowed wildly, resisting the binding power of this huge elephant's trunk.

Sun Yan only felt that he was in the palm of the giant's hand, and a huge force continued to contract, which actually made the bones of his whole body creak, and the severe pain made him frown.

This pain is still secondary, this [Rust Refining Demon Elephant] has a strange corrosive power, which is constantly eroding the surface of the Fenggang tortoiseshell, and a trace of it has penetrated into the meridians.

Fortunately, the defensive power of the [Ninety-Nine to One Technique] is extremely amazing, and the crazy circulation of those Fenggang forces can temporarily resist the invasion of this corrosive force, and the two sides have barely reached a balance.

"This corrosive power is like a rusty body, is this the characteristic of Uncle Iron Spoon's exercises?" Sun Yan was shocked in his heart, it was the first time he had encountered such a strange force and strength characteristic.

Fighting fate to turn [Ninety-Nine to One Trick], Sun Yan finally resisted the contraction force of this huge elephant trunk, and he secretly breathed a sigh of relief.

At this moment, Uncle Iron's voice sounded around again: "Hey, I was surprised to resist the restraint of the elephant's trunk so easily, I thought that this training alone, Ah Yan, would take you three days to complete." ”

In the basin, Sun Yan pursed his lips tightly and said nothing, trying to resist the strength of this demon elephant, and there was a connection. If it were normal times, he would definitely be proud and show off with Uncle Iron Spoon.

Immediately after, Uncle Iron Spoon's words changed: "Since we have resisted the elephant trunk restraint so quickly, then let's save time and advance the training content in three days." ”

What?!The training content after three days is carried out in advance?

Hearing this, Sun Yan's face suddenly changed, and before he could react, he saw that this [Rust Refining Demon Elephant] lowered his head, and the two sharp rust-colored tusks stretched out, and they actually stabbed straight at a rapid speed.

"Grandma is a bear, is there any mistake, Uncle Iron Spoon, you are a genius student who murdered the academy!" Seeing this scene, Sun Yan's face suddenly darkened, and he scolded wildly in his heart.

Bang!

Two rust-colored ivory tusks were pierced on Sun Yan's body, and the Fenggang tortoise shell on his body exploded into clusters of light, and wisps of Fenggang circulated wildly, as if they were about to be pierced apart by two tusks, and the layer of Fenggang tortoise shell was also flickering and dark, on the verge of disintegration.

At this time, the dragon-shaped light and shadow in the fire in Sun Yan's body suddenly coiled up, and the dragon-shaped aura overflowed in all directions, pouring into the limbs and hundreds of remains, quickly replenishing the loss of the Fenggang tortoise shell.

In these dragon-shaped breaths, there is actually a large amount of Fenggang's power, but in the Storm Prison, the Fenggang that Sun Yan can't absorb is absorbed and stored by the dragon-shaped light and shadow.

Now, Sun Yan's life is threatened, and this dragon-shaped light and shadow is to release the power of Fenggang again, so as to quickly strengthen the Fenggang tortoise shell.

Rumble......

I saw that under the attack of the trunk and tusks of the [Rust Refining Demon Elephant], the Fenggang tortoise shell, which was originally almost scattered, was condensed again, and burst out with even more dazzling brilliance.

On that layer of Fenggang tortoise shell, the wisps of Fenggang power became more and more agile and refined, showing subtle lines.

Silky pattern!

......

"It's ......"

In the huge basement, Uncle Iron Spoon's eyes opened suddenly, and the eyes of the rust-colored planet kept turning, reflecting Sun Yan's figure in the basin.

Thundered...... , a huge rust throne, rising from behind Uncle Iron Spoon, he slowly sat down on the throne.

This rusty throne is engraved with ancient patterns, rusty, exuding waves of decay and terrifying fluctuations, and the ground and walls of the entire basement also began to change color rapidly, forming an ancient rust color, exuding an ancient atmosphere.
