Because the battle points were sufficient, Chu Duan would enter the Ice and Fire Cave every day, allowing the power of ice and fire to enter the spiritual world realm for refining.

The life-and-death battle between Chu Duan and the Hades Clan was widely spread and spread, but after two months, it gradually subsided, but everyone was worried about it in their hearts.

That battle was a battle between the geniuses of the human race and the geniuses of the Hades race, and it was also a small-level confrontation between the two races, winning or losing was not only the lives of the two, but also an honor for the two races.

Whether it is for Hades or Chu Duan, only victory is allowed and defeat is not allowed.

Chu Duan devoted himself to cultivation and tried his best to improve his strength.

It's just that cultivating to his realm, it is very difficult to improve in any aspect.

For example, in the sword art realm, if you want to continue to improve in just a few months, it is impossible to reach the seventh layer, unless there is some particularly big adventure.

In the past two months, Chu Duan's harvest has not been small, the most obvious is that his spiritual mind is once again full of the spiritual world, and because he was tempered by the power of ice and fire in the Ice and Fire Cave, he has become more and more refined, which will undoubtedly save Chu Duan a lot of time.

At night, Chu Duan came to the stargazing platform again.

It only took two nights for Chu Dui to use the power of the stars to refine his spiritual thoughts and fuse them with the power of the stars of the Seven Killing Stars, and on the third night, Chu Dui was ready to condense the sixth star of ideas.

Nandou refining the Yi Sutra, up to now, Chu Duan has been cultivating for several years.

Six chapters correspond to six stars, and only after cultivating all six chapters can it be regarded as truly practicing the Nandou Refining Intention Sutra.

Now, Chu Duan has completed the fifth chapter and is about to carry out the sixth chapter of cultivation.

"I don't know the way, condense into the sixth star of thought, and cultivate into the Nandou Refining Sutra. Will there be any changes?" Chu Duan looked up at the stars in the sky, feeling the clear and rich fluctuations of the power of the stars, muttering to himself, in his heart, there was a little expectation.

Is it just to add a star of ideas, to increase the amount of spiritual thoughts, or can it cause some qualitative change?

Let's wait and see, Chu Duan said to himself secretly.

Get rid of all distracting thoughts, and wholeheartedly cultivate the sixth chapter of the Nandou Refining Sutra: Seven Killing Stars.

Tianfu Star, Tianliang Star, Tianji Star. The sky is the same star, the sky is the same star, and the seven killing stars form the Nandou.

At the beginning of the refining, a large amount of pure Seven Killing Star Power continued to pour into Chu Duan's spiritual realm until it was saturated.

Then came the crucial moment, condensing and compressing the sixth star of thought.

Chu Duan's spiritual world realm was already stable enough, but in the process of condensing and compressing the sixth star of thought. But it has been impacted again and again, and almost all the barriers in the spiritual world are in danger of being broken.

Chu Duan's mind was tense, ten thousand times more tense than walking a tightrope.

The most once compressed. With a bang, a terrible explosion made Chu Duan's consciousness almost collapse, and the whole person was dizzy as if he was drunk.

A full quarter of an hour later. Chu Duan's consciousness recovered, and when he saw the spiritual world, he was shocked.

I don't know when it happened. The scope of the Spiritual World Realm has expanded, reaching twice its original size, becoming more wide, and the barrier of the Spiritual World Realm has also been strengthened several times, and in addition, six stars of thought are hanging above the Spiritual World Realm, shining with the light of the stars.

The six stars of thought are exactly the same as the position of the six stars of the Southern Dipper in the sky of the Archean realm, forming the shape of a bucket.

Vaguely, Chu Duan could feel that there was a trace of connection between the six stars of the Southern Dipper in his spiritual realm and the six stars of the Southern Dipper in the sky of the primeval realm.

This connection was so wonderful that it made Chu Duan sink down again, running the Nandou Refining Intention Sutra, and in an instant, the six stars of the Spiritual World Realm released brilliant starlight from the first Tianfu Star to the sixth Seven Killing Stars.

At the same time, the six stars of the Southern Dipper in the sky of the Archean realm also became blazing and brilliant in turn, and the power of the stars emitted became clearer and richer.

The connection between the Six Stars of the Spiritual World Realm and the Six Stars of the Heavenly Southern Dipper of the Ancient World Realm was continuously strengthened and deepened, reaching the point where even Chu Duan could clearly feel the connection between the two sides even if he didn't deliberately sense it.

Under the association between the Six Stars of Mind and the Six Stars of the Southern Dipper, and driven by the Refining of the Meaning Sutra of the Southern Dipper, the two sides resonated and flickered together, as if the Six Stars of Thoughts in the Chu Twilight Spiritual World Realm were the replica of the Six Stars of the Southern Dipper.

The starlight of the six stars of the Southern Dipper starts from the first star and spreads to the sixth, so that the six stars of the Southern Dipper are connected in an instant, and from the sixth star to the first star, so that a complete cycle is formed, and all the star power runs through and spreads among the six stars.

The six stars of the mind in the Chu Twilight Spiritual World Realm are also like the six stars of the Southern Dipper in the Archean Realm, which are connected into a whole.

The power of the mind is like the power of the stars, which circulates among the six stars of the mind.

Every time he cycled, Chu Duan had a feeling that his spiritual mind was undergoing some kind of change, what was the specific change, and now he was in a state of wholeheartedly cultivating the Nandou Refining Intention Sutra, and he didn't check his feelings properly.

Chu Duan, who was immersed in cultivation, couldn't feel the passage of time at all, when the night passed and the day fell, the power of the stars of the Southern Dipper became very weak and intermittent, even if there was an increase in the stargazing platform, even if Chu Duan's preoccupied feeling, it could not be stable.

In an instant, Chu Duan came to his senses and found that it was dawn.

After leaving the stargazing platform and returning to the humble world, Chu Duan calmed down and carefully examined the various changes in the spiritual world.

The expansion of the spiritual world realm is the most intuitive, and the spiritual ideas have also increased a lot, and Chu Duan found that with the cultivation of the sixth chapter of the Nandou Refining Intention Sutra, there seems to be room for improvement in the purity of spiritual thoughts.

In addition, Chu Duan also made a very important discovery, his spiritual mind was a little more active than before.

The spiritual mind was a little more active, and at first Chu Duan didn't know what the use of the Dao was, but after trying, he found that the control and mobilization of the spiritual mind became easier, although it was not very obvious, but Chu Duan's sense was very keen, and he could still distinguish it.

It's just as if it originally took a point of force to mobilize a point of mental thought, but now to mobilize a point of mental thought, it may only need to consume 0.9 points of force, which not only saves a little bit of force, but also is better controlled.

This is undoubtedly an astonishing find.

At this point, Chu Duan's cultivation plan was adjusted again.

There are still four months to go, twelve hours a day, Chu Duan in addition to taking out one hour to refine the Heavenly Desolate Sword Yuan, and taking another hour to rest and recall, and then taking out another hour to cultivate the Burning Blood Transformation, the remaining nine hours, six hours are used in the Ice and Fire Cave, while letting the power of ice and fire enter the spiritual world to quench, while practicing swordsmanship and power control, the last three hours, in the stargazing platform, practicing the Nandou Refining Sutra, and enhancing the activity of spiritual ideas.

The condensation of the sixth Mind Star made Chu Duan's spiritual mind much stronger, and the expansion of the Spirit World Realm also made him more than double the power of ice and fire, in this case, Chu Duan was able to enter the deeper part of the Ice and Fire Cave, reaching a distance of two thousand meters.

The power of ice and fire here is richer and purer, the quenching effect is better, and the efficiency is higher.

Chu Duan's feeling was not wrong, after the sixth star of thought was condensed, the spiritual idea could indeed continue to be refined and become more refined, and the most important thing was that the potential of the spiritual idea was still being developed.

Once the Spiritual World Realm is filled with the Spiritual World Realm again, it will be twice as much as what was developed before, but unfortunately, Chu Duan has already practiced the Nandou Refining Intention Sutra, and without the seventh chapter, even if the Spiritual Mind is filled with the Spiritual Realm again, he will not be able to condense it into a Star of Thought.

As soon as these primitive spiritual ideas were developed, they were also tempered by the power of ice and fire in the Ice and Fire Cave, and quickly became refined, catching up with the power of ideas in the Star of Ideas.

Once the Spiritual World Realm was once again filled with spiritual thoughts, and these spiritual thoughts were refined to the level of purity like the Star of Consenting Thoughts, then the power of the minds that Chu Duan was able to use would be further enhanced.

Chu Duan was cultivating, and the rest of the Heaven Shaking Clan, Qin Shanhe, Tu Gang, and Tangtai Streamer were also cultivating hard, and with the Yin Evil Crystals given by Chu Duan, they didn't need to enter the Valley of Ten Thousand Evils at all, and through the way taught by Chu Duan, they used the special Nine Turns Heart Seal Technique they had cultivated to cooperate with the power of Yin and Evil to refine the power of mystery.

In addition, they also practiced blood burning and swordsmanship, etc., from all aspects, to improve their own strength as much as possible, every point of their strength is the improvement of the overall strength of the Heaven-Shaking Clan, even if they can't keep up with Chu Duan's footsteps, but they can't be left too far behind.

Even though the Demon Slayer Clan hated Chu Duan very much, they couldn't attack Chu Dui, even if Chu Duan entered the Scarlet Wasteland, they didn't dare to attack him, otherwise, the Sword Palace would definitely find out, and the end of the Demon Slaying Clan would come.

The Demon Slaying Team, which has lost in a row, has plummeted in prestige, and has been suppressed by the other two super teams, but fortunately, the Demon Slaying Team has a deep heritage, and the captain Hai Wuya is ranked second on the Sword Palace Billboard, with all kinds of background support, the Demon Slaying Team is still one of the three super teams.

The life-and-death battle between Chu Duan and Hades was inevitable, and the Demon Slayer team focused on how to restore their prestige and vitality and the direction of sustainable development.

And in the past six months, the Pluto Clan has been more active than usual, and in the Scarlet Wasteland, there is often news that people of any race have died at the hands of the Pluto.

During this period of time, on the side of the Tianfeng Sword Palace, most of the teams did not enter the Scarlet Wasteland, but stayed in the Sword Palace and worked hard to cultivate, waiting for the time to come, at that time, it was the life-and-death decisive battle between Chu Duan and the Hades God Clan.
