After Xiao Yi retreated, he immediately cast his astonishing finger and launched several invisible sword qi that shot into the eyes of the iron-backed desolate bear.

The iron-backed desolate bear's eyes closed, and as a result, the incomparably sharp invisible sword qi only left a few white marks on the iron-backed desolate bear's eyes.

Roar!

As if enraged by Xiao Yi's attack, the iron-backed desolate bear began to go berserk, only to see the four-legged iron-backed desolate bear light up with a misty light, and a pair of forelegs slammed down on the ground: "Roar!"

There was a loud bang, and the ground shook and the mountains shook, and the terrifying waves of air swung in all directions, and the ground in front of the iron-backed bears advanced like waves seven or eight feet away, and the ground cracked open, and the nearby bushes were knocked down one after another.

Although Xiao Yi quickly dodged with the light power, he was still a little dizzy by the shock wave, and his steps were a little vain, Xiao Yi saw this, and immediately carried the light power of the volley void crossing, and stepped in the air, completely eliminating the shock wave from the ground.

At the same time, Xiao Yi's body quickly moved towards the iron-backed barren bear, and sure enough, as expected, although the iron-backed barren bear had great strength and strong defense, its reaction speed was indeed not very good.

With the help of his extreme speed, Xiao Yi immediately changed his strategy and engaged in guerrilla warfare against the iron-backed desolate bear, and the Evil Wave Knife continued to attack again and again.

The iron-backed wild bear kept roaring, roaring, waving its palms, and constantly slapping towards Xiao Yi, but it was never able to touch Xiao Yi.

Gradually, the wounds on the iron-backed desolate bear were constantly superimposed, and under each knife, Xiao Yi was able to bring out a deep wound on the iron-backed desolate bear's body, although it could not be fatal, but it was able to accumulate such attacks, gradually reducing the strength of the iron-backed desolate bear.

Roar!

As it continued to be hurt and repeatedly failed to fight back, the iron-backed wild bear roared frantically, and the hair on its whole body looked very strange under the rendering of blood at this time, like a hedgehog in anger, those long hairs of twenty or thirty centimeters stood up one by one, making its already huge body seem to be more than doubled.

At the same time, the iron-backed desolate bear rushed frantically in the direction of Xiao Yi, and the terrifying momentum was terrifying. The wind howled, and everywhere it passed, the shrubs and boulders were all turned into powder.

Xiao Yi relied on the ingenuity and speed of his body, and he kept flashing step by step, and he was able to accurately dodge the attack of the iron-backed wild bear every time, although there were occasional dangers, but they were still able to dodge.

After a while, dense wounds appeared on the iron-backed desolate bear's body, and there were more than fifty or sixty wounds all over his body, dripping with blood, but none of them could be fatal.

Seeing this, Xiao Yi took a deep breath, and under the rapid movement, his body exploded back one after another, and in the blink of an eye, he opened up the distance, holding the knife in one hand, and the other hand instantly took out the Xuantie dagger from the martial arts system, and after holding it, he began to condense the innate true qi.

Ninety percent of the innate true qi was directly instilled on the Xuantie dagger, and the edge was exposed, forming a cold glow, and the cold qi was pressing. In this way, Xiao Yi pressed towards the iron-backed desolate bear again, and when he dodged to the iron-backed desolate bear, Xiao Yi made a mistake, and the dark iron dagger stabbed fiercely at the throat of the iron-backed desolate bear, which was the weakest part of its defense.

"Poof!", the Xuantie dagger, which was wrapped in innate true qi, stabbed directly into the throat of the iron-backed desolate bear, and directly collided violently with the iron-backed desolate bear's strong body.

The innate true qi was the first to erupt, like thunder on the flat ground, roaring and piercing, and the violent fluctuations brought up amazing waves of qi, spreading towards the surroundings, and suddenly set off a gust of wind, blowing the gravel on the ground flying wildly.

Oh!

A painful roar sounded, in the blasting sound it was thrilling and heartbreaking, blood was splattering, and the innate true qi directly destroyed most of the defenses of the iron-backed desolate bear, and the iron-backed desolate bear with hair all over its body was already fluttering in the sky at this time, and the remaining bit of it also looked scorched and black and crooked.

I saw that a blood hole about the size of a fist appeared in the throat of the iron-backed wild bear, and the blood was dripping and spraying out like a fountain.

Roar!

What shocked Xiao Yichen was that even after receiving such an injury, the iron-backed desolate bear still stood tall, worthy of being one of the fierce beasts known for its defensive power, and after being stimulated by the pain, the iron-backed desolate bear roared again and erected a huge bear paw again, and slapped at Xiao Yi.

Xiao Yi didn't say a word, withdrew the Xuantie dagger, and while dodging back, the Evil Wave Knife met the bear paw of the iron-backed desolate bear, preventing this crucial blow.

Without giving the Ironback Bear any respite, Xiao Yat once again bullied himself and repeated his tricks, this time the target of the attack was still concentrated in the throat of the Ironback Bear.

Perhaps sensing the continuous flow of life force, the iron-backed desolate bear actually exploded again in the last bit of time, and the power of the bloodline hidden in its body suddenly exploded, causing its size to suddenly skyrocket by one-third.

"Bloodline madness?" Seeing this scene, Xiao Yi was shocked, secretly screaming that it was not good, and hurriedly flashed to the side. Once the Ironback Bear goes berserk, it can instantly increase its strength by a large amount, or even directly double it. Only a few iron-backed bears with pure bloodlines and good qualifications can be displayed at critical moments.

Once the bloodline frenzy is cast, the strength of the iron-backed desolate bear will suddenly increase significantly, comparable to the innate martial artist, and it is generally impossible to kill it if it is not an innate martial king powerhouse.

Because if it weren't for the powerhouse of the Innate Realm, the momentum of the iron-backed desolate bear's instant explosion would be able to suppress the opponent, and with the next attack, it would be able to turn the tables in an instant.

It's a pity that Xiao Yi was already a powerhouse in the innate realm, and the momentum of the iron-backed desolate bear did not affect Xiao Yi, so in the face of the attack that followed by the iron-backed desolate bear, Xiao Yi easily flashed.

Fortunately, at this moment, the iron-backed desolate bear is already on the verge of death, even if such an outbreak can bring it a temporary boost. However, it also couldn't hold out for long, believing that if it delayed for a while, the wound in that throat would be enough to kill it.

As soon as he thought of this, Xiao Yi started a guerrilla war, delaying the battle time, using his speed advantage to constantly dodge the attacks of the iron-backed desolate bear, and even sometimes took the time to counterattack, making the iron-backed desolate bear's angry roar endless.

It's just that the roar of the iron-backed bear became smaller and smaller, and finally gradually became hoarse and weak.

After about a cup of tea, the Ironback Bear slowly fell to the ground with a low roar, and finally lost its life completely.

Xiao Yi waited patiently for a while before rushing to the iron-backed desolate bear, took out the dark iron dagger, and began to harvest directly.

A dark Demon Yuan Pill appeared in Xiao Yi's hand, this was the twentieth Demon Yuan Pill he obtained, and it was also the first half-step innate Demon Yuan Pill.

Xiao Yi, killed the first half-step innate fierce beast in his life, and even infinitely connected to the innate beast, after cleaning up everything, Xiao Yi hurriedly ran into the distance, the smell of blood here will soon attract other fierce beasts, and the battle movement just now is very likely to have attracted the attention of others.

Even if it doesn't attract the attention of others, it is located on the edge of the water flow, and there are often people coming out, and for the explorers in the Yanwang Ancient Tomb, the water flow area is always a place full of dangers and fierce beasts.
