"Whoosh!"

Lin Feng's gaze fell on the Tianxuan Treasure Halberd, and with the rotation of his gaze, such a Tianxuan Treasure Halberd, which had reached the level of an immortal weapon, was like a streamer flashing, and it directly disappeared into the burning Northern Immortal Emperor Flame.

"Boom!"

Almost at the moment when the Heavenly Xuan Treasure Halberd was submerged, the Northern Immortal Emperor Flame, which was burning, burst out with even more brilliant fireworks.

"Zizi ......"

In the midst of the flames, the Heavenly Xuan Treasure Halberd, which was swallowed by the four-colored fireworks of the Northern Immortal Emperor Flame, began to burst into bursts of sizzling sounds.

That feeling, as if it was a new tempering of the Tianxuan Treasure Halberd.

The Northern Pluto Emperor Flame, as the second-ranked existence among the twenty-seven different fires in the starry sky, in addition to its devouring attributes, the fireworks themselves have an extremely powerful burning power.

Now, after devouring the Blue Thunder Heavenly Fire, the Red Lotus Industry, and the Yuan Shen Gang Fire one after another, the power of its fireworks has skyrocketed to a new height.

Rao is the Heavenly Xuan Treasure Halberd, which has reached the level of an immortal weapon, but it is still unable to resist the power of the fireworks of the Northern Emperor Flame.

However, after all, Lin Feng's current realm strength is limited, so the power of the Northern Hell Emperor Flame released by the Alien Fire must also be greatly reduced, which is not as good as one-ten-thousandth of the true power of the Northern Hell Emperor Flame. In this case, if you want to completely melt the Heavenly Xuan Treasure Halberd, it will take at least a few days.

"From coming to the Immortal Fall Swamp to look for the Yuan Shen Ganghuo, to inadvertently coming to the Beginningless Ruins, to now, it has taken too much time. ”

"Before coming to the Immortal Fall Swamp, there was news that it was not far from the day when the Heavenly Realm Mountain would open. It is necessary to complete the extraction of the three exotic treasures as soon as possible, and then complete the tempering of the Hybrid Element Flying Sword and upgrade the grade. ”

"Let's come along. ”

In a whispered voice, Lin Feng directly summoned the glazed holy armor and the child and mother god pestle into the burning Northern Hell Emperor Flame.

He knew that it would take a considerable amount of time from melting the three immortal artifacts to extracting the Sealed Demon Immortal Rock and leaving the Fire True Essence and the Broken Sky Xuansha.

If you want to complete the extraction at the fastest speed, it is the best way to refine the Mixed Yuan Flying Sword to the grade of the pinnacle treasure weapon, and to refine the three immortal weapons together.

It's just that in this way, the wear and tear of the body will become extremely terrifying.

But fortunately, there is a Chaos Qiankun Pill with energy sealed in the body, which can replenish the body in a timely manner. It's just that this kind of supplement has a limited amount of time to maintain, and if the extraction can't be completed within this time limit, even if it has the maintenance of the Chaos Qiankun Pill energy, it can't continue like this.

Minutes ticked by.

One day, two days, three days.

Four days, five days.

Six days, seven days.

Before you know it, seven full days have passed.

Within seven days, the three immortal treasures, also under the tempering of the alien fire, were completely extracted from the initial softening, then melting, and then to the three exotic treasure essences.

"The extraction of the Sealed Demon Immortal Rock, the True Essence of the Separation of Fire, and the Broken Sky Xuansha is finally over. ”

"It's a pity, the three immortal weapons of the Tianxuan Treasure Halberd, the Glazed Holy Armor and the Son and Mother Divine Pestle!"

After the extraction was over, Lin Feng couldn't help but sigh with some regret.

Although from the time he made the decision to the end of the extraction, he did not have the slightest regret in his heart.

But after all, they are three genuine immortal weapons, and the regret in my heart is unavoidable.

"The extraction is over, and the next step is to combine the Illusory Sea Separation Fire Dark Iron, as well as the Spiritual Celestial Glass and the Ink Frost Celestial Stone, to refine and reforge the Hybrid Yuan Flying Sword. ”

Lin Feng said, summoning the Mixed Yuan Flying Sword, as well as the Illusory Sea Separation Fire Dark Iron, the Spiritual Illusion Heavenly Glass, and the Ink Frost Heavenly Stone, all of them into the raging Northern Hell Emperor Flame.

Under the incineration of the Northern Emperor Flame, the six kinds of exotic treasures were softened little by little, and then melted. When they all turned into puddles of liquid, they began to slowly merge into the Mixed Yuan Flying Sword under the guidance of Lin Feng's consciousness.

The entire process of integration lasted for about two hours, and after the six kinds of exotic treasures melted, all the liquid turned into was integrated into the Mixed Yuan Flying Sword, and after it was fused with it, the entire sword body suddenly released an unprecedented sense of hardness.

It was the hybrid flying sword that had just been fused, and it was still in a state of softening, but the sharpness brought by the eyes was far from being comparable to before.

"Whoa!"

After the tempering was over, Lin Feng began to fade away from the Northern Immortal Emperor Flame.

Almost at the moment when the raging fireworks were extinguished, the Mixed Yuan Flying Sword, which had been softened under the fireworks, quickly returned to normal.

"Buzz!"

The hybrid flying sword that returned to its normal form shook violently in the air.

There was a huge buzzing sound, and it exploded violently, and in an instant, the entire Treasure Pavilion was completely filled. Not only that, but it seems that the entire Beginningless Gate, and even the entire Beginningless Ruins, are shrouded in a monstrous noise.

"Whew!"

The concussive sword body burst out with a loud buzzing sound, and a sharp sword light also soared out from the sword body.

It was like a lightsaber slashing through, and everywhere it went, the heaven and the earth were divided into two. Looking up, you can clearly see the clear crack that was cut open in the entire Treasure Pavilion, the moment the lightsaber slashed. The whole deep sharpness is like the deep trench that cracked in the ground after an earthquake.

"Just between the shocks of the sword body, the sharp edge released is so terrifying. ”

"The Mixed Yuan Flying Sword that has entered the peak treasure level is really much more powerful!"

Lin Feng's gaze fell on the huge crack that had been cut in the void between the sword shocks, and he nodded with satisfaction.

It seems that the Mixed Yuan Flying Sword at this time is a truly sharp divine weapon, and before the fusion of the six kinds of exotic treasures, it is just a piece of broken copper and iron. The gap between the two is a world of difference, and between them, there is a chasm that Kenben cannot cross.

"Slash!"

Feeling the sharpness of the sword that burst out between the vibrations of the sword body, Lin Feng was uncontrollable, turned around and walked out of the Treasure Pavilion.

The moment he just walked out of the Treasure Pavilion, the Mixed Yuan Flying Sword had already been sacrificed in the air, and then slashed down with the momentum of thunder.

"Boom!"

It's just that the moment the sword body is cut out, a monstrous sword light has already diffused out.

Five hundred meters, one thousand meters, one thousand five hundred meters, two thousand meters.

3 km, 5 km, 7 km, 9 km, 10,000 m.

The frantically spreading sword rays finally broke through the length of 10,000 meters.

From the sky above the beginningless gate, it stretches all the way to the portal 10,000 meters away.

......

"This ...... What's going on?"

Almost in the monstrous sword, spanning a distance of tens of thousands of meters, from the beginningless gate to the moment of the portal, all the fierce beasts within such a range were deeply shocked.

They walked out of the place where their lair was located, focusing all their attention on such a one, tens of thousands of meters long, across the sky on the sword light, and could no longer move the slightest.

Although the sword gaze was like a real giant sword, it was still easy to see the problem with their vision. All the fierce beasts couldn't imagine what a powerful magic weapon it was, and it could condense tens of thousands of meters of sword light.

"The sword is as solid as a real giant sword, and it can be tens of thousands of meters long, I am afraid that the grade of such a magic sword must at least reach the level of a consummation treasure weapon, and even, most likely, it has reached the level of an immortal weapon. ”

The judgment of these fierce beasts is not bad.

Although the Mixed Yuan Flying Sword is still the grade of the pinnacle treasure weapon, with its special and powerful origin, its power is the best among the countless consummation treasures.

Not only that, but to a certain extent, it can be comparable to a real immortal weapon.

"In the Beginningless Ruins, I can't remember how many years it has been, and there have been no immortal cultivators. Could it be that kid?"

Outside the level of the shocking and flying sword, these fierce beasts began to guess the origin of the monstrous sword.

Just listen to a fierce beast in the shape of a python, thoughtful words.

"Looking at the situation of the monstrous sword, it seems that it came from the place of the Beginningless Gate, could it be that kid entered the Beginningless Gate?"

Another beast in the shape of a giant tiger, Ying He's voice sounded immediately after, and it had exactly the same opinion on the origin of the sword.

However, what made him even more curious was how Lin Feng, an immortal cultivator, had managed to raise his strength and the power of the magic weapon to such a terrifying level in just a few dozen days.

"There is a strong prohibition in the Beginningless Gate, and it can't be broken through at all, but there is no other reason to explain it except for that kid!"

This is a tree that has grown for an unknown number of years, and it has given birth to a creature, and among all the fierce beasts in this range, it can be regarded as having a relatively deep understanding of the entire Beginningless Gate.

It didn't think that Lin Feng would be able to break through the prohibition of the Beginningless Gate and enter it, but other than that, he couldn't think of any other reasonable explanation.

"Entering the beginningless gate, it seems that this is the only possibility. ”

"Judging from the situation of the sword alone, both the power of the flying sword and the strength of that immortal cultivator are far more powerful than when they slashed the Purple Lightning Spray Cloud Beast. Presumably, it was within the Beginningless Gate that some kind of power was inherited. ”

"This human immortal cultivator is really lucky!"

In short, the words of many fierce beasts are full of the same envy.

Even if it has passed, and it has been countless years, they can still clearly understand the power of the beginningless gate in the past from the memory inheritance left by their fathers, or from the stories of other fierce beasts.

Although it has been lonely, after all, it has been brilliant in the entire starry sky, and it is absolutely enviable to be able to get some inheritance in it. Moreover, in just a few tens of days, the strength and power of the magic weapon can skyrocket to such a level, and this alone is enough to prove the strength of the inheritance.
