Chapter 521: Mountain and Sea Realm

One, two, three.

Chen Fei continued to refine the black stone and integrate it into the Qianyuan Sword.

Because the hostility of the strangeness towards Chen Fei continued to deepen, the phantoms around him became more and more. Later, Chen Fei did not need to use the spiritual charm, and the phantoms appeared automatically.

This level of hostility made Chen Fei a little creepy, just like a giant monster, looking down on you, sitting on pins and needles, and it is impossible to describe this feeling.

Chen Fei calmed down, that is, he knew that there was something wrong with this fourth-level strangeness, otherwise Chen Fei would have run as far as he could.

The spirituality and material of the Qianyuan Sword were improving at an astonishing speed, but Chen Fei found that the effect of the black stone was decreasing, but the decrease was still within the acceptable range.

After Chen Fei added a piece of black stone as big as an adult's fist, the sword sound of the Qianyuan Sword reached its peak.

Chen Fei killed the phantom and introduced it into the refining heart formation while watching the changes of the Qianyuan Sword.

The sharp light circulated wildly on the sword of Qianyuan Sword. With each turn, the spirituality of Qianyuan Sword increased by one point until it reached a certain critical value.

"Zheng!"

The sound of the sword was like a clear spring. Although it was not loud, it was endless. The shadows that surrounded and killed were forcibly swept away. Countless undetectable sword energy flowed around, like a domain.

Chen Fei couldn't help but smile. Qianyuan Sword was so easily upgraded to the level of a mid-grade magic weapon.

Chen Fei stretched out his hand to hold the hilt of Qianyuan Sword, sensing the excitement from Qianyuan Sword, and slightly shook the sword body, and the killing intent filled all directions.

With Chen Fei's current strength, combined with the Qianyuan Sword at this moment, his combat power will be further improved. Facing the general middle stage of Heqiao Realm, he can already compete for a long time.

It is still not enough to defeat, but Chen Fei can easily retreat if he wants to.

Of course, if you really face a desperate situation and the four-door forbidden method is fully activated, what will happen at that time, you can only know it after you really fight.

The light of the Qianyuan Sword flows, and then gradually stabilizes. Chen Fei continues to take a fist-sized black stone and integrate it.

The spirituality of the Qianyuan Sword began to fluctuate violently again, but compared with just now, the amplitude of the fluctuation is much smaller, and the improvement of the material has also slowed down a lot.

After a while, when the changes tend to stabilize, Chen Fei carefully observed the Qianyuan Sword and found that the effect of the black stone on the Qianyuan Sword was indeed weakened a lot.

If such a black stone can increase the transformation progress of the Qianyuan Sword by 10% when it is a low-grade magic weapon, then now it has become a medium-grade magic weapon. The effect of the same size of black stone is directly cut in half.

However, if it is cut in half again, this black stone is also taken for nothing, and Chen Fei has not lost anything.

It’s just that Chen Fei originally thought about whether this black stone can repair the spiritual treasure in the space grid. Now it seems a bit whimsical.

If you think about it carefully, you will understand that there is a paradox in it.

If the spiritual treasure can rely on the black stone to repair, then during the hundreds of years or even thousands of years of suppression, the spiritual treasure probably directly began to absorb strange power to restore itself.

It would not have come to the point where both sides were injured.

The black stone can improve the Qianyuan Sword because the black stone belongs to the fourth-level object, and the Qianyuan Sword is only the third-level lower-grade level. The difference between the two is not a few small grades, but a whole big grade.

The idea in Chen Fei's mind flashed through, but the action in his hand did not stop. Chen Fei killed as many phantoms as there were around, and then refined them into black stones and integrated them into the Qianyuan Sword.

Kill, refine, merge, and improve!

The black fog around Chen Fei's body seemed to condense into substance, and the hostility was like a natural disaster, which made people terrified.

But Chen Fei just carried it hard, and nothing else happened except that the phantoms around him became more and more dense.

As for the corrosion of the black fog to the body, it has been strengthened a lot, but it is still a long distance to let the body of the Heqiao realm decay. This fourth-level weirdness is too outrageous.

Except for the fourth-level in essence, all other things are weakened, even the third-level weirdness is inferior.

As for the pollution of the mind, Chen Fei directly attacks with the projection of the mind, and naturally can't hurt Chen Fei's mind body at all.

Qianyuan Sword rushed all the way to the position of the top-grade magic weapon. Although the effect of the black stone is getting weaker and weaker, it can't stand the large number of black stones.

In the case of poor effect, it is completely compensated by quantity.

If this gets a top-grade magic weapon, Chen Fei's combat power will be increased. At that time, whether it is an ordinary middle-stage Heqiao realm or the genius of those top forces, Chen Fei will have the confidence to face it.

Unless the opponent is also holding a top-grade magic weapon, it is naturally another situation.

Qianyuan Sword trembled violently. This extreme and rapid improvement is also a huge test for the spirituality of Qianyuan Sword. Especially the spiritual essence absorbed before, it was already exhausted when it was upgraded to a medium-grade magic weapon.

Therefore, the violent fluctuation of spirituality at this moment, for Qianyuan Sword, it needs to rely on its own foundation to resist.

If it can resist, the spirituality and material will continue to rise. If it can't resist, then this upgrade will stop here, and Chen Fei may have to change to another magic weapon to upgrade.

Low-grade magic weapons and medium-grade magic weapons are completely different prices.

However, Qianyuan Sword is extremely tough, and it doesn't show any posture that it can't resist. Every time the spiritual tearing and the cleaning of the filth in the sword body, Qianyuan Sword resists it all, allowing itself to continue to jump.

The Refining Heart Formation was flashing with a faint light, and a black stone was gradually taking shape in it. Suddenly, Chen Fei's mind in the sea of ​​consciousness was shaking violently, and Chen Fei subconsciously looked back.

Because Chen Fei was standing on the edge of the black fog at this moment, he could see the distance clearly when he turned his head.

The wind was light and the sky was blue, but in Chen Fei's eyes, or in the eyes of the sky, it seemed that there was a great terror approaching.

In the black and white tones, a thick line was suddenly inserted into the world composed of countless lines.

Purely subconsciously, Chen Fei withdrew the Refining Heart Formation at his feet, and even abandoned the black stone that was about to take shape. In the sea of ​​consciousness, the mind was violently warning.

Even when the black fog almost enveloped Chen Fei just now, his mind had never trembled like this.

Chen Fei took a step back, as if he had escaped from the ink color. Before Chen Fei could take the next step, he suddenly saw a figure appearing several miles above the black fog.

The figure stood there, nothing unusual, but it was this inconspicuous appearance that was the biggest anomaly.

Chen Fei was only a few miles away from the figure. At this distance, ordinary people might only see a black dot, but in the eyes of the Heqiao realm, it was easy to see the face clearly.

But Chen Fei saw this person at this moment, just a blur. Not only was his face blurry, but his entire figure was blurry in Chen Fei's eyes.

Mountain and Sea Realm?

A thought flashed through Chen Fei's mind, and this thought quickly filled Chen Fei's mind.

Chen Fei had seen the peak of the Heqiao realm, and he had seen more than a dozen of them at once. Those people were so majestic that they could overwhelm other Heqiao realms, but Chen Fei could see the gap between the two sides after all.

In the final analysis, the peak of the Heqiao realm is still within the scope of the Heqiao realm, and it is also within the scope that Chen Fei can understand. The Sansheng Broken Shadow Sword that Chen Fei is practicing now also records some of the wonders of this realm.

But the Mountain and Sea Realm was a blank to Chen Fei. Chen Fei didn't know what power the other party had, nor did he know how to break through. This was why Chen Fei came here in the first place.

And at this moment, this person gave Chen Fei a blank feeling.

Although the person was there, Chen Fei could not sense anything. He could see with his eyes, but what he saw was also blurry.

The figure in the sky did not respond to Chen Fei's gaze at all. Chen Fei only saw the figure's hand move slightly, and the vitality of the heaven and earth within a few miles suddenly rioted.

More than a dozen figures were thrown out of the black fog involuntarily. They stayed here to study this fourth-level strange Heqiao Realm.

Most of these people were in the early stage of Heqiao Realm, but there were also a few who had reached the middle stage of Heqiao Realm, and even one was in the late stage of Heqiao Realm.

But no matter which realm they were in, these people were swept out of the black fog without any resistance at this moment, and staggered and fell several miles away.

Chen Fei also felt a huge force falling on him. When Chen Fei reacted, he had already fallen on a slope.

Powerless to resist, and unable to resist, when you feel the power, it is actually too late.

"Bang!"

A sound like fine iron being torn apart sounded, which was so harsh that Chen Fei couldn't help but narrow his eyes. Then, the black fog covering a mile in the distance suddenly rose into the air.

The more it flew, the smaller the range of the black fog became. When it arrived in front of the figure, the black fog had turned into a small black bead, which was held in the hand of the figure.

A seemingly shrill scream sounded in Chen Fei's ears, and the mind in Chen Fei's sea of ​​consciousness trembled violently. The roar of the dragon elephant faintly shook, resisting the scream.

But the next moment, the screaming sound that seemed to be directly in the soul stopped abruptly. Chen Fei looked up at the sky and found that the figure had disappeared.

From the appearance of the figure to the forcible pulling up of the fourth-level weirdness, less than a few breaths of time passed.

The area where the black fog was originally located was left with only a huge deep pit, which was the place where the spiritual treasure was discovered.

The dozen or so Heqiao Realm that stayed here rushed towards the deep pit, but just halfway, the only one in the late Heqiao Realm shouted, and the others couldn't help but stop.

There should be good things in the deep pit, but it was obviously considered as a sure thing by the late Heqiao Realm.

"Mountain and Sea Realm!"

Chen Fei looked at the place where the figure originally stood in the air, and a gleam of light flashed in his eyes.

The next moment, Chen Fei soared into the sky and flew towards the passage of the Endless Sea.
