The rooms are large, including practice rooms, but they are also very basic, with little unnecessary frills.

Beifeng looked at it, and he didn't care, he had to suffer hardships to become a master.

The north wind sat cross-legged and thought silently.

"The realm of Wannian Venerable has reached great perfection, and no one is stronger than me, but the breakthrough is too fast and needs to be precipitated. ”

The north wind muttered to himself.

At this time, it was easy for Beifeng to break through to the Cave Void Realm, after all, the space in his body had already been formed.

Not only formed, but also the foundation of the emperor!

The cultivation of the Cave Void Realm is to open up a space in the body, but when the Cave Void Realm is in the Cave Realm, the space in the body is not stable.

It can only be regarded as the prototype of a small world, and it is easy to collapse when subjected to strong external forces.

In this realm, ordinary martial artists are easily unwilling to show their falsehoods.

This realm needs to continuously consume a large amount of heavenly materials and earth treasures to make the cave void stable and transform into a small world.

Every time you break through a small realm, the area of the void will also start to grow exponentially!

Until the consummation of the cave void and the nine tribulations of the emperor, at the moment of breaking through to the emperor realm, the rules of heaven and earth bless its cave void and let it transform into a real small world!

And the north wind is different!

When the north wind broke through to the Millennium King, the qi and blood fused perfectly, causing the space in the body to appear early!

The space that appears is not a void!

No matter how small the space in the north wind is, it is still a real space, which is not the same as the void of the cave!

As the North Wind cultivates and improves, the small world in the body is becoming more and more perfect!

This is the foundation of the North Wind!

When ordinary people tried so hard to break through to the Cave Void Realm, and even had to use external forces to break through, the north wind had already laid the foundation for becoming an emperor!

Even so, in the face of the temptation that is close at hand, the north wind is still unmoved!

If you don't polish this realm to the extreme, the north wind will not break through!

Once broken through at this time, the perfection that the north wind had previously pursued in each realm would be broken.

It seems that the strength of a body will be stronger if it breaks through to the Cave Void Realm, but in fact, the combat power will become weaker!

If the realm of Wannian Zun reaches perfection and then breaks through, when it breaks through to the realm of the Cave Void, its combat power will be stronger than that of the breakthrough when the realm of Wannian Zun is not perfect!

One step stronger, one step stronger!

Even if the combat power is one line higher than the opponent, it can turn the tables at a critical moment!

"The core of my martial arts idea is leisure, which is the foundation, followed by the sword intent, which is the foundation of protecting the Dao. ”

Beifeng's expression flashed with hesitation, and finally gritted his teeth, "I can't bear the child to catch the wolf!"

"Buzz!"

A monstrous sword appeared in the north wind's hand, buzzing.

"Shark Tooth Sword, I have drunk the blood of many strong people along the way, and my spirituality is getting stronger and stronger. ”

The North Wind Horizontal Sword was in front of him, and he gently stroked the sword body with one hand.

"Zheng Zheng!"

The shark-toothed sword rattled, and the blade trembled, accompanied by the sound of killing.

The powerful spirit of the north wind is almost like condensing into the essence, breaking out of the body!

The terrifying spiritual power is like the water of the heavenly river, and the sound of Fuxi is constantly washing on the sword body!

At this moment, the spirit of the north wind is like turning into a sledgehammer, constantly forging the shark tooth sword!

Countless fires burst out, and the north wind emitted light!

The vision lasted for three moments before it gradually dissipated, and the light on Beifeng's body disappeared, and he saw Beifeng's face pale, like a serious illness.

But Beifeng had a smile on his face and stared at the Sharktooth Sword.

The sharktooth sword didn't seem to have changed in the slightest, but Beifeng could feel the difference in this sword.

Not only has the spirituality been improved, but even the strength and sharpness of the sword itself have also been improved!

As soon as the north wind moved, the shark-toothed sword turned into countless black powders and disappeared.

"With his own qi and blood, spiritual sword cultivation really works!"

The north wind muttered to himself, his eyes showing a strange light.

It's no wonder that there are countless people in Earth legends who hold swords all the time, not just cultivating a preliminary connection with swords.

He is also using his own spirit to feed the sword with his body all the time!

When the strength is low, raising a sword in this way is like overdrawing one's own potential, and it often amazes the world like a meteor.

Ten years of sharpening a sword, a sword can be shocking!

Ten years of time is spent on cultivating sword weapons, and once you start it, it will shine like a meteor in the starry sky, which is enough to kill many people who are higher than your own cultivation!

And those with low strength raising swords are overdrawing their potential, and such an amazing sword may not have a chance to come out for the second time in their lives!

But the north wind is different, its strength is terrifying, and its spirit is dozens of times that of a martial artist of the same level!

Such a terrifying cultivation is enough to make Beifeng have no worries.

"It's a pity that the barren gold contained in the body of this Emperor Realm Desolate Clan is not enough to be tempered with my strength, and if I want to ask the sect to help, I need a lot of contributions. ”

The north wind muttered to himself, a pity.

If the Wild Gold is extracted and added to this Shark Tooth Sword, it will be enough to make the quality of this sword go to the next level!

Time passed slowly, and the north wind lived a very fulfilling day.

Carry the Yuan Force, let it run to all aspects of the body, and every Sunday of operation, the north wind will feel its progress.

Although the realm has reached the Great Perfection of Ten Thousand Years, after every time he runs the Yuan Force, Beifeng feels that his limit has been broken!

At the same time, thanks to the special features of this small world, there is no need to worry about the consumption of resources.

Every moment is swallowing the blood and aura of the outside world, so that the cultivation of the north wind has been steadily improving!

It can be said that even if you don't pass the assessment of Qingtianwei, it is only worth practicing in this small world for a month.

In addition, the north wind also spends time raising swords!

Every time he raised the sword, the north wind could feel the change in the shark tooth sword.

Stronger and sharper, the quality is starting to increase!

What followed was the initial establishment of a wonderful connection between the north wind and the sharktooth sword.

When you hold the shark tooth sword, you will feel a sense of intimacy and blood connection.

This is a feeling that has never been felt before, and under such a close connection, it is enough to make the strength of the north wind break out beyond the tenth layer!

The Shark Tooth Sword was originally a sword for drinking blood, accompanied by the north wind to fight, drinking the blood of the enemy, and the quality was much stronger than when it was just transformed.

Then get the north wind to spare no effort to warm up with spirit and spirit, until this time finally caused a qualitative change!

"Buzz!"

The Sharktooth Sword floated in the void, trembling slightly, and layers of spatial ripples spread out in all directions.

A faint thought was born in the body of the sword, like a flame in the wind.

With the trembling of the shark tooth sword, the shark tooth sword cracked!

Cracks opened on the long blade, bursting out with countless rays of light and particles!

"Click!"

A small fragment detached from the sharktooth sword, then shattered into dust.

Beifeng didn't have any surprise on his face, but with some expectation, he quietly watched this transformation.

Like a phoenix nirvana, reborn from the ashes, the same is true of this shark tooth sword at this time!

The entire sword body was covered with cracks, and after the metal on the exterior was shed, the dark red sword body was revealed!
