In chaotic times, one can become a martial immortal.

Led by Zheng Shuang and Zhang Yida, along with more than ten experts from both families, Lu Yuan ventured dozens of miles into the Black Cloud Mountains.

"Brother Yuan, according to the information we have, this Ironback Bull is not only incredibly strong, but also has thick skin and flesh, and it even seems to have gained intelligence. It is probably much more difficult to deal with than ordinary beasts."

As he walked briskly forward, Zheng Shuang spoke solemnly to Lu Yuan.

"That beast is indeed very ferocious. My Zhang family sent several teams of experts to surround it, but the result was heavy casualties. Even the two guest elders who were about to enter the ranks were seriously injured."

Zhang Yida nodded solemnly, then turned to look at Lu Yuan and said, "Brother Yuan, although you are strong, you are still only a qualifying candidate..."

Although he didn't finish his sentence, the meaning was self-evident.

Although Lu Yuan is indeed very powerful, able to kill the Thunder-Handed Tiger with a single strike, he might not be able to contend with a beast like the Iron-Backed Bull, and it would be difficult for him to even escape unscathed.

Hunting this Ironback Bull is virtually impossible unless you have a weapon comparable to a divine weapon or your strength is on par with a true rank-one martial artist.

"It's alright, as long as we find it, I'll take care of the rest!"

Lu Yuan, however, remained expressionless and smiled faintly.

He was well-prepared for this trip into the mountains. He not only changed to a superior sword forged from fine iron, but also brought dozens of specially made iron bullets in case of emergency.

Moreover, he had already mastered the Copper Skin technique, and with the Swift Wind Step at its peak, even if he couldn't defeat that Iron-Backed Bull, he could still ensure his safe retreat.

"Roar...roar...roar..."

They continued on for a short while when suddenly a roar filled with anger rang out.

"Seventh Master, that Iron-Backed Bull is in the ravine ahead; our men dare not get too close!"

At this moment, several Zheng family experts, their bodies stained with blood, rushed over and spoke to Zheng Shuang.

"Ninth Master... quick... retreat quickly, that Iron-Backed Bull has gone mad!"

Before anyone could speak, several more Zhang family experts, covered in blood, ran over in a disheveled state.

"Roar! Roar! Roar..."

Sure enough, the roars seemed to become even more frantic.

"You all wait here, I'll go check it out!"

After saying something to Zheng Shuang and Zhang Yida, Lu Yuan rushed towards the direction from which the roar came.

Although it was now dark and windy, and the depths of the dense forest were pitch black, it had no effect on him.

After reaching the next level, his five senses not only became more acute, but also, thanks to the profound power of his inner strength, he was able to see in the dark, and everything within a ten-foot radius was clearly discernible.

The entire Black Cloud Mountain Range resembles a sleeping dragon lying across the land.

Lu Yuan swiftly rode on the back of the sleeping dragon, not only as if walking on flat ground, but also at an ever-increasing speed.

Although the Swift Step was not activated to its full potential, it still left a series of afterimages behind him.

Before long, Lu Yuan finally saw an extremely large figure in the mountain hollow not far ahead.

Compared to ordinary bison, this iron-backed bull is at least one size larger.

Its sharp horns gleamed with a cold light, as if they could pierce through anything.

It was as if it was covered in thick black armor, and ordinary swords and other sharp weapons would probably not be able to harm it in the slightest.

As you can see, there are a lot of human body fragments and broken pieces of various weapons scattered on the ground nearby, which obviously belong to the experts who came to try their luck earlier.

"Master Lu, Seventh Master Zheng sent us to help!"

"Master Lu, Ninth Master Zhang also said that we must bring you back safely no matter what!"

At that moment, several more figures quietly appeared behind Lu Yuan.

"You can harass and restrain it; I'll handle the rest!"

Lu Yuan nodded slightly and said directly.

Upon hearing his words, the men, all of whom were at the Transformation Realm, hesitated slightly but did not say anything more before quickly dispersing.

Some people harassed the other with throwing knives, others shot arrows directly from bows, and still others threw stones.

Clearly, they all knew how powerful the Ironback Bull was and dared not get close enough to attack it.

Unfortunately, this Iron-Backed Bull was indeed thick-skinned and tough. Although the attacks of these men at the Transformation Realm were all imbued with sharp energy, they still couldn't harm it in the slightest.

These attacks, in fact, only served to further ignite its ferocity.

Its massive body, like a steel chariot, was madly crushing everything around it.

Whether it was grass, trees, soil, or rocks, they were all crushed to dust.

Its sharp horns, in particular, would likely be so powerful that even a shield forged from fine iron would be unable to withstand its fierce impact.

What's even more terrifying is that its speed surpasses that of even a martial artist at the Transformation Realm.

Just as a master of the Zhang family was about to be caught, his sharp horns were about to pierce through his body.

It was at this moment that Lu Yuan made his move.

As afterimages appeared, he arrived beside the Iron-Backed Bull in the blink of an eye.

Without any fancy moves, he simply slashed down with one stroke.

The blade's edge, propelled by internal force, was not only three inches long but also much sharper.

"Pfft!"

As expected, the blade easily pierced the Ironback Bull's body, and blood splattered everywhere.

However, after penetrating only half an inch, it seemed to get stuck.

"Master Lu... is amazing!"

Even so, the eyes of the several men at the Transformation Realm were still filled with astonishment.

No matter how they attacked before, they couldn't even damage the silver-backed bull's hide, far less than Master Lu's single strike.

"roar!"

The Ironback Bull, in pain, let out a roar and then turned and ran away.

"You all wait here!"

After Lu Yuan turned and spoke to the group of men at the Transformation Realm, he used his Swift Wind Step to catch up with them.

Although the blade was sharp enough to wound the iron-backed bull, it still couldn't inflict fatal damage.

A half-inch deep wound might be serious on a human, but on this iron-backed bull, it's at most a scratch. Even a hundred more cuts wouldn't necessarily kill it.

Therefore, Lu Yuan planned to use his true trump card, the Blazing Sun Sword Qi.

"Boom... Boom..."

The iron-backed bull rampaged through the dense forest, as if nothing could stop it.

However, although it was fast, it was still not as fast as Lu Yuan, who had already pushed the Gale Step to its limit.

"roar!"

As if knowing it couldn't escape, the Iron-Backed Bull roared to the sky and charged madly at Lu Yuan.

Its eyes were bloodshot, as if it wanted to use its incredibly sharp horns to pierce through the tiny insect in front of it.

Facing this frenzied, iron-backed bull, Lu Yuan remained expressionless, his figure suddenly flashing.

The next moment, he pushed his internal energy to its limit and then slashed down with his sword.

A nearly three-foot-long crimson sword aura instantly burst forth.

"laugh!"

A soft sound.

The blazing sun sword energy not only easily sliced ​​through the flesh of the Ironback Bull, but also severed its tendons and bones without any resistance.

The next moment, the huge bull's head rolled to the ground, and its massive body collapsed with a thud.

The cut was charred black, and even the blood was instantly sealed off.

Lu Yuan was naturally very satisfied with the power of this sword strike.

Then he carried the bull's head in one hand and dragged its massive body with the other, heading straight back.
