"Boom!"

After Lin Feng took out the five different treasures used to refine flying swords, the palms of his left and right palms were spread out at the same time. The flaming flame of Beiming emperor had burned up.

After swallowing the green thunder sky fire, the red lotus industry fire, the yuan God Gang fire, the life spirit Yan and the ghost fire, the color of the Beiming emperor's flame has become golden green, red, white, green and blue.

The six color Beiming emperor's flame, just at the moment of burning, burst out an extremely terrible hot temperature. The fireworks are even more towering, just like the tumbling magma inside. The moment of burning, between heaven and earth, opened a towering fire curtain to carry out heaven and earth.

"Boom!"

Beiming emperor's flame, which has swallowed five different fires, has a terrible improvement in the power of fireworks compared with the original.

This towering fire curtain seems to have a terrible smell that can burn everything. In a trance, there is an illusion that it will be burned cleanly in the no beginning door and even the whole no beginning area.

"Thunderbolt cheerleading!"

"Zizi..."

The flame of the northern Ming emperor, under the terrible power of fire, five materials used to quench the Hunyuan flying sword first burst out a continuous sound of fried beans, and then began to melt soon.

Bit by bit of liquid, constantly delimited, slowly over time, the five kinds of exotic treasures led by meteorites have all melted into a pool of liquid. Five kinds of liquids interweave and converge into one.

Then it was extracted and purified.

"Whew, whew..."

Once these extracts were extracted, they began to enter the mixed flying sword rapidly.

With the injection of exotic treasure, we can feel the change of the mixed flying sword very clearly.

Not only is the hardness released from the sword body soaring. Even the sharp breath from above is soaring.

In this way, the time passed. Unconsciously, it was the next morning when the refining of Hunyuan flying sword was completed.

"Today's Hunyuan flying sword has been quenched."

"The product level, as expected, has reached the level of the lower product artifact of the first level."

"I really look forward to how much the power of Hunyuan flying sword can be improved after completing the leap from immortal to artifact?"

Lin Feng whispered to himself, which was a deep expectation that could not be suppressed in his heart.

It sounds like a leap between the most perfect immortal artifact and the first-order inferior artifact. However, this rank spans the big rank from immortal to artifact.

Therefore, even if it is just a leap in product level, the power improvement of flying sword has exceeded the improvement from inferior immortal tools to extreme and perfect immortal tools. Lin Feng felt the surging power of the flying sword after the promotion of the flying sword level. Lin Feng felt in a trance that even the strong person who has reached the second level of Mahayana can be hit hard with a sword if he can urge all the physical strength and cultivation level and hold the Hunyuan flying sword, which is an artifact at the lower level of the first level, Even kill it directly.

"The Hunyuan flying sword, from extreme to perfect, is promoted to a first-class inferior artifact. After that, you can see how powerful it is."

When his eyes turned, Lin Feng quickly made up his mind.

Step by step, I started up in the air. I didn't stop until I stepped hundreds of meters high.

"Feng'er, Lin Feng, brother Feng... What does he want?"

Lin Feng's behavior soon attracted the idea of his parents.

When practicing last night, they noticed that Lin Feng's refining of Hunyuan flying sword had just ended this morning.

"Can we say that the upgrade of flying sword is to try its power?"

"Yes, it must be!"

In a whisper, the four parents quickly determined the answer.

After all, it is clear at a glance that the advanced level from immortal to artifact has been completed and the terror of the power of Hunyuan flying sword has been improved. Even after they paid attention to today's Hunyuan flying sword, they could feel the terrible smell that was obviously stronger than last night.

"Boom!"

Lin Feng, hundreds of meters above the sky, concentrated and held his breath, clenched his flying sword with both hands, and slowly raised it over his head bit by bit.

The mighty sword burst out.

Just for a moment, the sword Qi rising into the sky has disappeared into the sky and has no end.

"Cut!"

At this time, Lin Feng held the sword in both hands and cut it out.

"Click!"

There is no language to describe the speed and terror of the sword.

Even if Lin Feng had cut out with his sword in both hands, the sword Qi pointing straight to the sky still kept the posture of rising to the sky and remained motionless. Not only that, the range of Lin Feng's sword fingers did not change, as if the sword he cut with all his strength was just a breeze.

Only after a few breaths did a huge crack burst between heaven and earth.

Not only that, this crack, also in front of the center of heaven and earth as a starting point, continues to spread forward.

Ten kilometers, a hundred kilometers.

Three hundred kilometers, five hundred kilometers.

Seven hundred kilometers!

It didn't stop until it spread for a full 700 kilometers.

When you look up, you can't see the marginal cracks at a glance.

In a trance, it gives people an illusion. It seems that the whole ruins without beginning are cut in two under this sword.

Until this time, the towering sword Qi that originally pointed to the sky was fleeting and disappeared.

"The level of flying sword, after reaching the artifact, the power increases. It's really terrible!"

Lin Feng was very excited.

This is speed and sharpness. Only when it reaches an extremely terrible extreme can it show.

"The sword in feng'er's hand is really powerful!"

"After nearly five breaths, the sword Qi flashed and disappeared, and the world burst into a huge gap. It's impossible to imagine how fast Lin Feng's sword was!"

"Brother Feng, the power of this sword feels like... To split the world!"

"If this sword is put on the earth, I'm afraid it's enough to cut a complete hole in such a large earth!"

In Wushi gate, the four parents who threw all their attention suddenly lost their mind.

A moment later, the four people looked at the gully of heaven and earth that almost penetrated the whole ruins of no beginning, and shouted excitedly.

"The improvement of the power of flying sword is almost as expected."

"Even, strictly speaking, it is more powerful than I expected."

"It seems that the old Hunyuan flying sword must be a sacred weapon. Moreover, even among the sacred weapons, it is the most outstanding and rare existence!"

Whispered to himself, Lin Feng took back the Hunyuan flying sword.

The realm strength has reached his current level. If he wants to improve, even if he looks at the whole Xianmen five domains, there are few places where he can have the opportunity to improve quickly.

The only hope is that, known as the whole immortal gate, from the hinterland of the Wuwu sea, which is mysterious, dangerous and full of opportunities.
