"Although thousands of years have passed, after all, it is the magic circle left by the peak powerhouse of Yuanying, and if you want to break it, I'm afraid it's still not so easy!"

Lin Feng muttered to himself, his two fingers were like knives, raised high, and slashed down in the air.

The flesh of the five elements immortal body was perfect, and the violent qi raged out, directly condensing a giant blade at the finger end with the power of qi, and then slashed into the air.

The giant blade was not large, only more than a meter long, but the sharp aura that overflowed from it was powerful enough.

"Buzz!"

The power of the giant blade is incomparably terrifying, enough to crack the mountains and split the rocks.

However, the slash landed on top of the Blinding Circle, but it did not cause any fluctuations. Like a drop of water, dripping into the lake, creating insignificant ripples that can be almost completely ignored.

"It's strong enough!"

"However, with this Mixed Yuan Flying Sword, it can also be broken!"

After a simple temptation, Lin Feng slowly narrowed his eyes and summoned the Mixed Yuan Flying Sword out of the air.

"Mixed Element!"

After the flying sword burst out, it was directly in mid-air.

"Boom!"

Above the sword body, a violent and powerful aura raged in an instant.

Immediately afterward, the sword burst out, and in an instant, it spread out a length of thousands of meters.

Raising his eyes, it was like a giant blade that was really thousands of meters long, horizontal in mid-air.

"Boom!"

The sky-covering giant blade slashed down, and the aura that burst out was extremely violent, and almost in the moment of the slash, the void was cut through it like a curtain.

At first glance, it was as if there was a huge opening, which quickly spread from the sky to the ground. It was as if the world in front of him was separated in half with this huge crack that ran through the heavens and the earth.

Before the sword light arrived, except for the gray mist blinding array, the ground within a few thousand meters before and after was all under the ravages of the sword qi, and a shocking crack opened. It is very deep, to a depth of more than ten meters underground.

However, such a monstrous sword, which was not necessarily terrifying, still failed to cause real damage to the Blinding Circle. However, the fluctuations of the gray mist became much more violent, and the waves kept shaking violently.

"Slash again. ”

Lin Feng once again raised a thousand meters of sword rays, and continued to slash down in the air.

After this slash, the gray mist, the degree of fluctuation, became more violent again.

"The third slash. ”

"Fourth slash. ”

“......”

"Tenth slash. ”

After ten slashes in a row, the gray mist finally cracked into a fine line in the violent fluctuations.

"Finally some rifts have been broken!"

Lin Feng's narrowed eyes burst out with a burst of light.

The solemn face finally appeared, a little smile.

This tiny crack in front of him will be the breakthrough of the entire gray dense burst. It's like a complete hard ice surface, it's hard to break through, but once a crack appears on the ice, it's much easier to break through other places.

In the eleventh slash, small cracks began to become visible.

The twelfth slash opened several cracks one after another.

......

The twentieth slash has already laid out more than a dozen shocking cracks.

Twenty-first slash.

Twenty-second slash.

......

Twenty-seventh chop.

Lin Feng continued to urge the Hybrid Flying Sword one after another.

Finally, when the monstrous sword slashed down for the twenty-seventh time, the gray mist that had become tattered could no longer withstand the power of the sword and exploded.

"Boom!"

A moment later, the gray monstrous mist that exploded disappeared, and a completely different new picture clearly appeared in front of Lin Feng's eyes.

This was an independent room, the hard door weighed tens of thousands of kilograms, and fortunately, Lin Feng's strength was amazing now, otherwise, even if he broke through the gray mist, he wouldn't be able to push the door open.

"Whew......"

As soon as the door opened, a blinding red light burst out.

In an instant, the entire place where the Wuji Sect was located was shrouded in a red light. The room was filled with an incomparably strong red light, as if it was a sea of red, and there was nothing else except the red light.

At the same time, there was an incomparably hot breath rushing towards him. It seems that at this moment, the entire place where the Wuji Sect is located has become a furnace, and the hot people can't breathe.

In the red-glowing room, the temperature is even hotter, and the feeling it brings to the eye is like a steel furnace. Not to mention people, even if it is hard steel, if it is thrown into it, it will be directly melted in an instant.

"I want to see, what treasure is hidden in here?"

Lin Feng slowly narrowed his eyes and stepped in.

His body, which was comparable to the pinnacle spirit weapon, was much, much harder than the extraterrestrial meteorite, and naturally it was not comparable to steel. This heat, so hot that it could melt steel, did not work at all for him.

If he wanted to, it wouldn't be much different from basking in the warm sunshine on a winter day.

"Here it is. ”

When Lin Feng entered, he saw a fiery red rock at first glance.

It was a fiery red rock the size of an ordinary basketball, and both the red light that shot out in all directions and the terrifying heat that diffused from it emanated from this fiery red rock.

"Away from the Fire Secret Rock!"

"It's !! from the Fire Secret Rock"

When his gaze fell on such a fiery red rock, Lin Feng's gaze could no longer move the slightest.

The Secret Rock of Fire is an extremely rare treasure of heaven and earth, and it is also a powerful treasure used to refine magic weapons. After the tempering of the fire secret rock, it can not only make the hardness of the magic weapon much stronger, but also make the attack power released by the magic weapon much stronger.

With the Mixed Yuan Flying Sword, the grade of the peak spirit weapon is now extremely high, and after being tempered by the Secret Rock of the Separation Fire, it is enough to make the grade of the flying sword enter the ranks of real treasure weapons.

"Haha!"

"That's great!"

It took a long time for Lin Feng to recover from that state of distraction.

In the excited laughter, there is irrepressible excitement in words and looks.

From more than 20 hidden ancestors of the four major sects, to Tianmen Sect, Tianxuanzong and Taixuanzong, his heart has changed from the initial expectation to despair little by little.

Originally, he thought that it was impossible to gain something from the four major sects, but he didn't expect that the last Wuji Sect, which had the least hope, would unexpectedly harvest the Secret Rock of Lihuo.

"Today, I will use this Separation Fire Secret Rock to refine the Mixed Yuan Flying Sword into the true treasure level. ”

Lin Feng's voice fell, and he sat cross-legged directly.

"Whew!"

The palms of the left and right hands spread out at the same time, and the blue-red flames after fusion rose up.

Whether it is refining elixir or refining and casting magic weapons, the control of flames is the most important. The more powerful the flame, the more proficient the control of the flame, and the higher the level of refining the elixir and refining the casting magic weapon.

In the universe, there are only more than 20 different fires, and each of them is the best flame for refining pills and casting magic weapons. And the fusion of different fires is the best of the best.

"Zizi ......"

Almost at the moment when the blue-red flame burned, the fiery red Flame Secret Rock began to burst into a sizzling sound.

Then, as the blue-red flames devoured it, it was directly melted.

"Boom!"

After the fire secret rock completely melted, the blue-red flames after the fusion of the different fires began to devour the Hybrid Yuan Flying Sword.

However, this seems to be able to melt the blue-red flames of all things in the world, and it does not melt the Mixed Yuan Flying Sword, but only turns the sword body and the whole body of the quenched red, like a long sword that has just been cast in the hearth.

"Boom!"

After the whole body of the mixed yuan flying sword became red, the yuan patterns carved on it with the power of the immortal yuan began to appear on the sword body, and a clearer outline appeared.

Not only that, but the depth of the Yuan pattern is still being intensified, as if the Yuan pattern carved by the power of this Dao Immortal Yuan is a deep ravine.

"Whoosh, whoosh......"

After melting, only a pool of magma remained, and with the emergence of the Yuanwen gully, it began to shoot into it in one go.

After that, it's like a stream flowing into a river, flowing slowly.

In this way, little by little, until the secret rock of the fire that had melted into a pool of magma, it was all injected into the Yuanwen gully.

"Buzz!"

The Yuanwen ravine that appeared out of thin air, wrapped in the secret rock of the fire that flowed into it, disappeared in a flash, returned to the sword body, and disappeared.

At this time, an unprecedentedly powerful momentum suddenly erupted from the sword's body.

That feeling is like the moment a missile is launched from the launch vehicle, and the breath that bursts out has the potential to destroy the world.

"Boom!"

The body of the sword shook, and the heavens and the earth were all filled with the silver cold light reflected by the flying sword.

It was as if this dense silver cold light was the only light in heaven and earth, and everything else was eclipsed in front of it.

"Sting!"

Silvery cold, with an incomparably sharp aura.

In an instant, the raging cold light tore the void through a huge opening, like thousands of flying swords, cutting through the sky, crisscrossing the heavens and the earth.

Not only that, but the entire place where the Wuji Sect was located, on the ground, was also completely shrouded in the cracks that were dense with Dao. Looking up, it seemed that even the sky above his head was divided into countless pieces by the violent and powerful edge.

"The Mixed Yuan Flying Sword has finally advanced to the level of a treasure weapon. ”

"Although it is still only the grade of the lower grade treasure weapon, the power of the flying sword is far from the level of the peak spirit weapon, which can be compared!"

Lin Feng looked at the Mixed Yuan Flying Sword suspended in front of him, revealing a smile full of excitement:

"With the Hybrid Flying Sword that has reached the level of a low-grade treasure weapon, even the super soldier headquarters base of the Mi Fang can break through. Although you can't really tell what the headquarters base of the rice side is, you can run away after making a fuss, and you can successfully escape. ”

"Werewolves, half-orcs, and vampires, the matter of the Pacific ambush, it's time to settle accounts with you!"
