The sword intent, the first into the eighth turn, the mystery of gold, also the first into the eighth turn!

Unless Chu Duan created the ninth handprint of the Nine Turns Heaven Shock Heart Seal, he would not be able to continue refining with the power of the handprint, but he would be able to continue refining with the help of the Yin Evil Cold Current until he reached the limit.

"Now, I can go deeper. With a smile, Chu Duan took a step forward and walked deeper into the Valley of Ten Thousand Evils.

The strong sword intent and the mystery of gold can resist the erosion of the Yin and Evil Currents to the greatest extent, and the deeper they go, the stronger and more powerful the Yin and Evil Cold Currents become.

Reaching out and grabbing it, all of a sudden, a piece of yin crystals the size of a fingernail was grabbed by Chu Duan.

The deeper he goes, the greater the probability of encountering Yin Evil Crystals, and Chu Duan plans to obtain more Yin Evil Crystals, even if he enters the Scarlet Wasteland, he can also refine his sword intent and mysteries to his heart's content.

What's more, the Yin Evil Crystals were also of great help to the rest of the Heaven-Shaking Clan.

Deep, deep, and deep, the strong spiritual intent was released, and although it was suppressed, within a radius of a few tens of meters, Chu Duan could still feel it.

As soon as he felt the Yin Evil Crystals appear, Chu Duan quickly moved his body and grabbed the Yin Evil Crystals.

It's just that moving within such a dense Yin and Evil Cold Current, is it huge, and the body shape is obviously contained, even if he uses the Golden Mystery of the Eight Turns to integrate into the body, it can't make the movement of the body reach the level when it is in the outside world, so Chu Duan missed some Yin and Evil crystals.

But he has no regrets, if he continues to go deeper, there will be more yin and evil crystals, and they will be bigger and purer.

Going deeper, he finally reached the limit and couldn't continue, otherwise, Chu Duan could be sure that the terrible Yin and Evil Cold Snap would cause great damage to his body.

Between the sword intent and the sword element. Resist the impact of the cold snap completely.

The cold current in this place has been so thick that although it has not yet condensed into a solid, it is already very viscous, much denser than mercury, and under the impact, the power is amazing.

Chu Duan could feel that here, his every move was greatly restrained. It takes more force than usual.

The good thing is that there are more Yin Evil Crystals here, and it won't take long to come across a piece.

The sword is an extension of the arm, the swordsman practices the sword, when the sword is practiced to the extent that the arm makes the fingers, and then continues to deepen the depth and transcendence, Chu Duan's sword practice has already exceeded the point of the arm making the fingers, as if the extension of the body.

He remembers. His teacher once told him that the highest level of sword training for a swordsman is to practice the sword to the point where it is integrated into the human body, bone marrow and soul, forming the imprint of the sword. Practice to the point that a sword and a person are formed in the womb at the same time, born and grown together, and the blood is connected and inseparable.

But. It's just a legend that has been passed down in the world of swordsmanship, and no one has ever reached it.

In the midst of the gloomy and cold current, Chu Duan drew his sword. With the help of the endless restraint of the cold current, he began to practice swordsmanship.

Practicing swords in such an environment, it is quite difficult to make each sword reach the most correct trajectory, and while practicing swordsmanship, Chu Duan should also pay attention to whether there are Yin Evil Crystals, once there are Yin Evil Crystals, he will stab or cut them off with a sword, and pull the Yin Evil Crystals into the space ring.

The battle points are sufficient, Chu Duan is not in a hurry to leave the Valley of Ten Thousand Evils, once the strength is almost consumed, he will retreat, let the strength and strength recover, and then continue to go deeper.

After repeating this again and again, Chu Duan's understanding of swordsmanship has improved slightly, and the swordsmanship field has made a breakthrough again, reaching the sixth layer, and the Yin Evil Crystals have also gained a lot.

At the same time, his sword intent and the mysteries of gold are constantly being eroded by the impact of the yin and cold currents, and they are also refining all the time, improving little by little, but the eighth level is already very high, and every bit of progress is very difficult.

A few days later, Chu Duan left the Valley of Ten Thousand Evils, and it was the time of night to go to the stargazing platform.

His spiritual thoughts were once again filled with the spiritual world, and it was time to refine and condense the star of his thoughts.

The Fifth Star of Thought!

The spiritual thoughts condensed into a bundle and spread to an altitude of four thousand meters, and the power of the stars was felt more clearly.

The fifth chapter of the Nandou Refining Sutra: Tianshu Star.

The power of the stars of the Tianshu Star was attracted and began to refine Chu Dui's spiritual thoughts, and ten days later, the spiritual thoughts were tempered to the limit by the power of the stars, and it was time to condense the star of ideas.

Condensing the star of thought, Chu Duan was already very proficient, condensing and compressing again and again, and under his strong will, it was finally condensed and formed.

The fifth star of thought hung in the sky above the Spiritual World, flickering with light, and Chu Duan felt that his Spiritual World, again, had become stable, and his five senses had improved again.

"There is also the last one......" Looking up at the starry sky, Chu Duan sighed faintly, unconsciously, it has been more than two years since he became an elite disciple, and the years are really ......

Put away your feelings, leave the stargazing platform, and come back next time, maybe half a year later.

Return to the Sword Tower to rest for a day and sort out the harvest by the way.

Eight turns of sword intent, eight turns of the mystery of gold, the sixth layer of the swordsmanship realm, a total of one hundred and thirty-three yin crystals were obtained, the smallest one was the size of a fingernail, several times larger than those soybean size obtained before, and the largest was the size of a pigeon's egg, and the yin evil power contained in it was even more pure and rich.

More than a hundred Yin Evil Crystals can be regarded as a very rich harvest, but Chu Duan is not satisfied, he wants more.

After a night's rest, Chu Duan went to the Valley of Ten Thousand Evils again, and he still had a lot of battle points, enough for him to stay in the Valley of Ten Thousand Evils for several months.

Continue to go deeper, once again to the limit of what you can reach, draw your sword and practice swordsmanship, and at the same time harvest the crystals of yin and evil.

When you are tired, you rest, and when your strength is exhausted, you recover, and so on and so on, undoubtedly, it is very boring.

But Chu Duan didn't care, he was completely immersed in it, and his swordsmanship was improving little by little, and the swordsmanship field was promoted from the sixth layer to the early stage......

Chu Duan was cultivating, Qin Shanhe, Tu Gang and Tantai Streamer were also cultivating, and Jin Yanlei was also cultivating in retreat.

The breakthrough in cultivation has increased the power of his divine thoughts a lot, and he must adapt to this increase and skillfully apply it to give full play to his power.

The time for the battle with Chu Duan is getting closer and closer, and Jin Yanlei has the confidence to win.

......

In a flash, a month has passed, and there are still two months left before the life-and-death battle between Chu Duan and Jin Yanlei.

In the thick and incomparably cold current, a golden light flashed, and the sword stabbed out, and in an instant, the surrounding cold current was pulled, twisted, and swirled in a whirlpool, and swept away to the side.

As the sword light danced, the yin and cold current was also distorted, and within the sword light, a clear piece appeared, and Chu Duan's figure was practicing sword in it.

The peak of the sixth layer of the swordsmanship realm, and there was only a very thin film between the seventh layer.

But it is not easy to pierce this film.

The obscure feeling made Chu Duan stop practicing his sword, and he knew that this was the limit, unless he could go further and make the binding force of the Yin and Cold Current stronger, it would be possible to further improve his swordsmanship and reach the seventh layer of the swordsmanship realm.

Exhaled a breath, put his sword into the sheath, and the yin and cold currents around him pounced again, and Chu Duan quickly retreated, he decided to leave the Valley of Ten Thousand Evils.

After a month of erosion and tempering, the sword intent and the mystery of gold have become more pure, but they still haven't reached the initial stage, the peak of the sixth layer of the sword art field, only a line away from the seventh layer, the biggest harvest is the crystallization of yin and evil.

Every day, Chu Duan can harvest at least a hundred Yin Evil Crystals, the smallest like a fingernail, the largest like a pigeon's egg.

Over the course of a month, the number of Yin Evil Crystals in his spatial ring continued to increase, and now, it had reached three thousand eight hundred and seventy-five, and after returning to the Sword Tower, Chu Duan began to sort it out.

He divided the three thousand eight hundred and seventy-five Yin Evil Crystals according to their size, which could basically be divided into three grades.

The smallest is a fingernail-sized Yin Evil Crystal, which Chu Duan defines as a first-class Yin Evil Crystal, while a Yin Evil Crystal the size of a pigeon's egg is defined as a third-level crystal, and a second-class one that is between the first and third level Yin Evil crystals.

According to the statistics after classification, the first level has the most yin crystals, with 2,150 crystals, followed by the second level, with 1,035, and the third level has the least, with 690.

If he continued to stay in the Valley of Ten Thousand Evils, of course, he could harvest more Yin Evil Crystals, but Chu Duan was unwilling, he had to do other things.

Pick up a first-level Yin Evil Crystal, absorb the Yin Demon Power into the Spirit World Realm, and after a short time, the Yin Evil Crystal disappears.

This is a crystalline body that is solidified by a pure yin and cold current, and there are no impurities, and it will disappear as soon as it is absorbed.

The incomparably pure power of yin and evil is in the spiritual world, and the soldiers are divided into two ways, wrapping the sword intent and the mystery of gold, constantly eroding, and the sword intent and the mystery of gold are also constantly fighting against and refining the power of yin and evil.

According to the current consumption rate, Chu Duan silently calculated, a first-level Yin Evil Crystal, when it could support him for two days of tempering, if the previous sword intent and the Golden Mystery were only seven turns, a first-level Yin Evil Crystal was enough for him to refine for four days.

"Level 1 is two days, Level 2 should be able to reach four days, Level 3 may reach six or even eight days. Chu Duan said secretly, but this was just his speculation, and whether it was true or not needed to be verified.

Take out the battle battle sword order, notify Qin Shanhe Tu Gang and Tantai Streamer, and gather in the sword tower.

Chu Duan explained the effect of the Yin Sha Crystal, and after that, he took out three hundred first-level Yin Sha crystals and distributed them equally to the three of them, with their level, one first-level Yin Sha Crystal was enough for several days, and one hundred could be used for hundreds of days.

Tu Gang and Yutai Streamer also took out their own things, two dark red pill gourds.

"Captain, this is the Blood Yang Pill. Tu Gang said with a smile.

The Blood Yang Pill was sent by the Hong Tianjiao and the Yutai Clan, but it was not much, after all, the value of the Blood Yang Pill refining was very expensive, and the range of use was relatively small, the total was only four hundred pills.

Chu Duan got two hundred grains, the other two hundred grains Qin Shanhe got forty grains, and Tu Gang and Tantai Streamer each kept eighty grains. (To be continued......)
