Regarding Chu Duan's challenge to the air battle, after a round of storm fever, it gradually fell silent, and it seemed that everything seemed to return to calm.

But everyone knew that at that time, in that place, there would be a battle awaiting.

The current calm is just for the violent craze of that time.

Qin Shanhe has not appeared since he was defeated by the sword of Sikong Battle again, and he should have stayed in his own sword tower to reflect and improve his strength.

The powerful pressure is like an invisible mountain, suppressing Chu Duan all the time, making Chu Duan feel the powerful pressure all the time.

Under this kind of pressure, Chu Duan was cultivating and improving himself all the time, because he knew very well that the air battle was very powerful, and his talent was also very terrifying, and he was many times stronger than the opponents he had encountered before.

Even, from the bottom of his heart, Chu Duan was not very sure that he would be able to defeat Sikong Battle in the challenge at that time.

Time, it's too short.

This is an extremely difficult challenge, and because of this, Chu Duan is so excited, that long-lost feeling, now, he has forgotten other purposes, just to fight with the air, a hearty battle.

In order to be able to fight a hearty battle with a fierce opponent like Sikong Zhan, Chu Duan needs to constantly improve his strength.

Any cultivation has not been put down, Chu Duan's whole person is like a tense stir, there is no time to rest at all, his brain has been running, and it has never stopped.

Fortunately, Chu Duan's soul is more than ten times stronger than that of ordinary swordsmen, and his spiritual intent is also very strong, so that he can support it and recover in the continuous consumption. A virtuous circle is formed.

Every day. Temper the Heavenly Desolate Sword Yuan. Then he practiced swordsmanship and everything related to it on the first floor of the Sword Tower, and then used the Nine Turns of Heaven Shock Heart Seal to refine the sword intent and tear the mystery.

The sword intent and the power of the tearing mystery have both reached the second turn, and the third handprint of the ninth turn of the Heavenly Earthquake Heart Seal has also been successfully created, and Chu Duan has already carried out the third turn of the sword intent and the power of the tearing mystery. Within two months, he was sure that he would refine the sword intent and tearing mystery to the third layer, and as for the fourth layer, it was estimated that there was no hope.

The refinement of the mystery of the sword intent every turn. The further you go, the more difficult it becomes.

Chu Duan's refining speed was already amazingly fast.

These cultivations are Chu Duan's cultivation during the day, and at night, Chu Duan will continue to go to the foot of Guanjian Peak, occupy a position, and cultivate the Nandou Refining Intention Sutra.

After seven days of cultivation, Chu Duan had been able to sense the power of the stars of Tianfu Star more clearly, and the power of the stars was also much smoother than before. The quenching efficiency has been improved.

Although there was still a long way to go before he practiced the Tianfu Star Chapter, Chu Duan could also feel it. His spiritual thoughts were refined a little more under the tempering of the power of the stars of Tianfu.

As for the amount of spiritual thoughts, it has not increased, and Chu Duan is not in a hurry, it is mentioned in the Nandou Refining Intention Sutra that all spiritual thoughts must be condensed into a star of ideas first, and the potential of spiritual ideas will be developed until the point of condensing the second star of ideas.

Chu Duan still can't reach the standard of the Star of Condensing Thoughts, but Chu Duan is not in a hurry, the Nandou Refining Intention Sutra is very subtle, far better than the Quenching Intention Gong, and it is natural that the cultivation progress is slow.

If you change to another sword, you may not even be able to get started.

In the blink of an eye, time passed like water, and it had been a month since Chu Duan challenged Sikong Battle.

In the middle of the night, under the Jianjian Peak, it was very empty.

The rules of the Archean Realm are many times more complete than those of the Ancient Sword Continent, so the night of the Archean Realm is also different from the night of the Ancient Sword Continent.

In the Ancient Sword Continent, the vision of the Yuan Extreme Realm swordsman was basically not affected by the normal night, but in the primeval realm, the vision of the Yuan Extreme Realm swordsman was only better than that of ordinary people in the dark night of the Ancient Sword Continent.

Even Chu Duan, who had cultivated the Sight Sword and whose eyesight exceeded that of ordinary Yuan Extreme Realm swordsmen, could only see some vague outlines in the middle of the night in the primeval realm.

Fortunately, the spiritual mind can still cover a range of 100 meters.

The cultivation of the swordsman is day and night, but the comprehension at the Guanjian Peak needs to be able to see the Jianjian Peak clearly, so late at night, at most you can only see the vague outline of the Guanjian Peak, how to comprehend.

Therefore, around Guanjian Peak at this time, there was only Chu Duan.

Chu Duan did not comprehend Guanjian Peak, with his eyesight, it was difficult to see Guanjian Peak clearly in such a late night, he was sensing the power of the stars of Tianfu Star, and introduced it into the spiritual world realm, refining spiritual thoughts.

After a month of cultivation, sensing the power of the stars of Tianfu and the two steps, Chu Duan was already very proficient, handy, and at ease.

After a month of tempering, Chu Duan's spiritual thoughts have been much purified, and tonight is a very critical night.

In the middle of the night, the power of the stars that could not be seen by the naked eye was guided by Chu Duan's increasingly powerful spiritual thoughts, and continued to enter Chu Duan's spiritual realm along an invisible line, constantly washing and refining the thoughts in the spiritual realm.

More and more of the power of the stars of Tianfu was channeled into the spiritual realm, and when it reached a certain level, the spiritual thoughts that spread out of Chu Duhui suddenly cut off the connection with the power of the stars of Tianfu.

In Chu Duan's spiritual realm, there are starry lights, like stars twinkling in the sky, and here, it seems to have become a miniature version of the night sky.

The spiritual mind was retracted, and it suddenly mobilized and swirled, as if a wind had rolled up.

The wind gradually intensified and intensified, turning into a storm, carrying a little starlight towards the center.

After a month of uninterrupted cultivation, Chu Duan had finally cultivated the first Tianfu Star Chapter of the Nandou Refining Intention Sutra to the point where he could condense the Star of Thought, and now was the time to condense the Star of Thought.

This process is very important, it cannot be interrupted, and it must be condensed in one go, otherwise if you give up halfway, it will shake the spiritual world and cause a certain amount of damage to the spirit world, and it will take a considerable amount of time to recover before you can condense it again.

That would undoubtedly waste a lot of time.

Chu Duan was so engrossed in his concentration that he completely forgot everything outside his body, even his body, and he seemed to have entered the spiritual realm.

The storm became stronger and stronger, and under the swirling of countless starlights, the spiritual storm intent became more refined little by little, and the speed of purification was faster than before, which surprised Chu Duan.

Time passed slowly, and under the silent Guanjian Peak, Chu Dusk, who was sitting cross-legged, the spiritual world was undergoing an evolution.

The rumbling sound resounded in the spiritual world, like the momentum of ten thousand horses galloping, overwhelming the mountains and seas, and it was extremely amazing.

As the storm of spiritual thoughts continued to rotate and shrink, Chu Duan felt a terrible pressure emanating from him, squeezing the barriers of the Spiritual World Realm, but fortunately, the Spiritual World Realm was strong and stable enough to be able to resist the squeeze of this pressure.

But the pressure was getting bigger and bigger, and gradually, Chu Duan seemed to hear the crunching sound of the spiritual world, as if it was crumbling, and it might be squeezed by the increasingly powerful pressure at any time.

When the pressure increased to the extreme, Chu Duan was a little worried about whether the barrier of the spiritual world could withstand the constant impact of pressure.

But this time is the last moment, the most critical moment.

The storm of spiritual thoughts has been compressed and condensed to the extreme, turning into a small whirlpool that rotates wildly at super high speed, and all the starlight has also gathered in it, and it seems that countless sparks collide in it, about to splash out, and it is extremely bright.

"Condensation!"

In the spiritual realm, Chu Duan's shout sounded, full of power, as if the majestic order of the gods high above.

In an instant, the vortex of spiritual thoughts collapsed again.

"Condensation!"

"Condensation!"

"Condensation!"

Every time he condensed, Chu Duan would feel a shock in the Spiritual World Realm, and the pressure that had been strengthened to the extreme seemed to be strengthened again, impacting the barrier of the Spiritual World Realm, and there was a feeling that a feather crushed Mount Tai.

At this time, if you don't succeed, you will become a benevolent, and there is no possibility of retreating.

"Condensation!" "Condensation!"

Three condensations in a row, almost superimposed, almost collapsed to the extreme, the storm of spiritual intent, suddenly trembled, collapsed again, almost condensed into solid, and then trembled violently, as if it was about to explode.

Chu Duan hurriedly suppressed it with his own strong will, causing the spiritual storm that seemed to be about to explode to tremble constantly, and the pressure on the spiritual world barrier, Chu Duan did not feel it.

At this time, only by thoroughly condensing the spiritual mind can we save the crisis at this time.

The pressure of the life-and-death crisis brought great impetus to Chu Duan, and a strong will exploded, once again suppressing the storm of spiritual thoughts and crushing them frantically.

"Condensation!"

As if the voice that was about to resound through the heavens and the earth sounded in the spiritual world realm again, the terrifying pressure that was surging like a huge wave was instantaneous, and the spiritual consciousness storm that almost collapsed to the extreme and exploded suddenly trembled, and all the power of resistance was shattered by Chu Duan's will.

The storm of spiritual thoughts collapsed again, and a series of explosions came out from inside, which caused Chu Dui's will to shake wildly, almost shattered, and his consciousness fell into a brief darkness in an instant.

It was only a hundredth of a second, and it was as long as the past ten years, and when Chu Duan came to his senses, he suddenly found that the huge pressure in the spiritual world realm had disappeared, and his spiritual world realm had more than doubled in stability without knowing the Dao.

The most important thing is that Chu Duan "saw" that there was a star suspended in the sky above his spiritual realm, emitting a faint starlight, and that star was the concentration of all his spiritual thoughts.

As soon as he felt it carefully, Chu Duan could feel that the spiritual intent contained in that star was extremely terrifying.

The appearance of the stars represents Chu Duan's cultivation in the Nandou Refining Sutra and the completion of the first chapter. (To be continued.) )
