The probability of the appearance of mutated iron-toothed tigers is very low, and only about one mutated species may appear in every 100,000 iron-toothed tigers.

Moreover, most of the mutated iron-toothed tigers do not survive to their juvenile years at all, so the mutated iron-toothed tigers that can really live to adulthood may only be one in a million.

Every mutated iron-toothed tiger, as long as it can reach adulthood, will have earth-shaking changes in its strength, which is far from being comparable to ordinary iron-toothed tigers.

The most terrifying thing is that the mutated demon beasts also have a common strength, once they become adults, they will automatically comprehend a kind of natural supernatural power.

The power of supernatural powers is far from being comparable to immortal law, which is enough to make the strength of mutation leap to a new level.

"It turned out to be ...... Mutant Irontooth Tiger !!"

The faces of the people of the Ice Spirit Sect, led by Bai Xiangfei and Bai Yu, changed suddenly.

The ice dragon array has reached the extreme, enough to trap any immortal cultivator and demon beast under the Jindan consummation realm, but there are exceptions to everything, a mutated iron-toothed tiger, although the realm is still at the peak of the Jindan realm, but the strength it has is even more powerful than the ordinary immortal cultivators and demon beasts in the Jindan consummation realm.

Therefore, don't look at such a mutant iron-toothed tiger, the realm is only the peak of Jindan, but the difficulty of dealing with it is even more difficult to deal with than the iron-toothed tiger of Jindan's perfection!

"No wonder, it didn't feel right before, it turned out to be a mutated breed. ”

Lin Feng narrowed his eyes with a smile.

"How's that okay?"

Bai Xiangfei was more than a dozen people, his face was solemn, and he didn't dare to slack off.

With their strength, it is impossible for them to be the opponent of the Mutant Irontooth Tiger, and now, the Mutant Sawtooth Tiger has gone berserk, even if they want to escape now, it is already too late.

"Bang! bang......"

The limbs of the mutant iron-toothed tiger suddenly exerted force.

The seemingly small soles of the feet directly stepped out of the four deep pits on the ground, and the surrounding ground was densely covered with cracks. It's like the ground that has been pllowed, one after the other, and it's shocking.

While stepping on the ground, the mutant iron-toothed tiger raised its head to the sky again and roared:

"Roar!"

The Iron Tooth is powerful because of the terrifying attack power of its sharp teeth, as well as its sonic attack.

Its teeth are hard enough to make countless spiritual weapons look inferior, and ordinary spiritual weapons, in front of its sharp and hard teeth, are completely like hitting stones with eggs. The mutated iron-toothed tiger, with a pair of teeth that are hard and sharp, is even more terrifying, enough to reach the level of a medium-grade treasure.

The roar can release a powerful and terrifying sound wave, like the roar of a Buddhist lion, which is within the range of the sonic attack, enough to cause the mountains to collapse and the rivers to stop. As for the mutated iron-toothed tiger, the power of the sound wave will also skyrocket, and under its sound wave, it seems that even the sky and the earth will burst unbearably.

"Boom!"

The terrifying sound waves, with a roar, spread in all directions.

It's like the mushroom cloud that covers the sky after a nuclear bomb is detonated.

Between heaven and earth, it seems that a shocking thunder that has been roaring for a long time has sounded, and it shook a huge piece of heaven and earth, and the clouds and mist rolled up, rolling up monstrous dust.

Under the terrifying impact of sound waves, all the parts within a radius of thousands of meters exploded, turning into countless debris. The earth was torn apart by the shocking cracks of the Dao, and at the same time, the deep pits of the Dao were exploded, and even above the sky, there were clouds and mist rolling, and the sky could not withstand the power of the sound waves, and it burst violently, and the Dao Dao air was broken, like a void black hole, densely covered in the sky.

"What a terrifying sonic might!"

"It's completely finished!!"

The faces of more than a dozen powerhouses of the Ice Spirit Sect suddenly changed.

In the face of such monstrous sound waves, they already felt a terrible death crisis.

With their realm strength, if they are affected by sound waves, there is only one final result, death.

"Shhh

Bai Xiangfei and Bai Yu also had the same solemnity on their faces.

Looking at each other, the two of them gasped in unison.

"It is impossible to truly grow without experiencing real life and death. ”

Lin Feng didn't make a direct move, but the Divine Mind completely shrouded the mutant iron-toothed tiger in the battle, as well as Bai Yu and Bai Xiangfei's dozen people, and every move could be seen by him at any time.

The purpose of the sect's experience is to let the disciples constantly improve their strength in the test of life and death.

Until the last moment, he will not come to the rescue easily.

"Array!"

"Water Spirit Shield Armor Great Array!"

Bai Xiangfei gave an order, and all the disciples of the Ice Spirit Sect hurriedly set up a formation.

With their strength, it is impossible to kill the mutant irontooth tiger and complete the trial task, and it is also hopeless to escape, the only way is to do everything possible to resist the attack of the irontooth tiger.

If they can successfully resist in the end, there will be a glimmer of life, otherwise, all of them will die here today.

"Whoa, whoa, whoa......"

The Water Spirit Shield Armor Great Array is a defensive array that uses the water spirit qi to gather huge shield armor. It is also Bai Xiangfei's more than a dozen people, under their current realm strength, the strongest defensive array that can be sacrificed.

Among the five elements of aura, the earth spirit qi has the strongest defensive power, followed by the water spirit qi. The surging water spirit qi is like the rolling torrent released after the flood of the river, setting off a monstrous wave at the same time, it quickly condenses into a shield armor in the shape of a wall.

The wall shield condensed with the aura of the water spirit was extremely hard, like a steel plate that had been tempered thousands of times, and there was not the slightest crack in sight. The feeling of hardness that comes from the sight is extremely terrifying, as if even an armor-piercing bullet with enough ammunition cannot penetrate it.

However, the seemingly hard Water Spirit Shield Armor was so vulnerable to the terrifying sonic attack of the Mutant Iron Tooth Tiger.

"Bang!"

"Click, click......"

A monstrous sound wave, crashing into the water spirit shield.

It's like smashing a huge porcelain with a hammer.

Although the porcelain is huge, it cannot resist the power of the hammer, let alone use all its strength, even if it is only a little more force, it can be smashed to pieces.

It was just a collision, and the water spirit shield armor could not withstand the power of the sound waves, and it exploded. Then it reverted back to the form of water spirit qi, permeating the heavens and the earth.

"Boom!"

When the Water Spirit Shield Armor bursts, the impact it releases is extremely terrifying.

The terrifying sound wave was swallowed up by this powerful impact, and in an instant, it also burst open.

"Hoo ......"

Seeing this, Bai Xiangfei and his entourage felt a little lighter, but the breath hanging in their hearts was hung high again before they had time to shout.

"Roar!"

The mutant iron-toothed tiger roared again, this time louder and louder, and the loud noise caused by it was even more monstrous.

The power of the furious sound waves is also unprecedented.

"Boom!"

The monstrous sound waves, carrying the overwhelming power of annihilation, rushed towards Bai Xiangfei and his party.

It was as if this was a sound wave that was enough to destroy the world, and everywhere it went, the sky fell apart, and everything was swallowed up and reduced to nothing.

"It's really going to be over this time......!"

Bai Yu and Bai Xiangfei sighed helplessly.

In the face of the even more terrifying power of the sound waves, they could no longer have the slightest thought of resisting.

After all, it was just the kind of sound wave that was much weaker just now, and they could only rely on the impact of the water spirit shield armor after it burst. Now in the face of the much more powerful power of sonic waves, the non-impact force of the water spirit shield armor after bursting is useless.

With their realm strength, they can't resist the power of sound waves at all, and once they are affected, their bodies will be destroyed, and their bodies and spirits will be destroyed at worst, and they will completely dissipate between heaven and earth.

"Dead!"

"Originally, when I avoided the iron-toothed tiger's sense of smell, I thought that I could kill the iron-toothed tiger immediately and take out the inner pill to complete the trial task, but I never thought that the final result would be...... I'm going to die!"

"Alas......"

After a helpless sigh, more than a dozen powerhouses of the Ice Spirit Gate closed their eyes in despair one after another.

The attack of the mutant iron-toothed tiger has arrived, there is no hope to dodge, there is no way to resist, and there is only one result waiting for them, and the flesh and soul together with the divine soul exploded in the monstrous sound wave.

"Slash!"

At the moment of crisis, Lin Feng had already sacrificed the Mixed Yuan Flying Sword in the air.

His purpose was just to make Bai Yu and these people feel a real threat of death, nothing more.

The sword soared, stretching out for thousands of meters, and it was even more condensed, like a real giant blade covering the sky, horizontal in the sky.

It seems that this giant blade that covers the sky is the giant axe in Pangu's hand, and one sword is enough to cut the sky and the earth under the sword.

"Sting!"

When the giant blade fell, there was no trace of the giant blade between heaven and earth, and only a silver light that penetrated heaven and earth remained.

The sharpness of the silver mang, which cannot be described in words, the moment it crossed the sky, it directly cut a huge gap in the huge void, as if the entire sky was divided into two under this silver mang.

The earth, unable to withstand the power of the silver mang, was cut a long hole, and looked down at the position of the mouth, and it was shocking to find that after the silver mang was cut off, it had gone deep to a depth of hundreds of meters underground.

That's all for the power of a slash.
