The cyan wind blade broke through the air and slashed towards the sword monument, and the sword that was cut out swirled around, and the raging flames appeared on the sword body, turning into a crazy burning fireball and bombarding out, the body rotated, and the sword circled around, sweeping through thousands of armies, and the sword was filled with a layer of frost, turning into ice and following the fireball.

With the sword moving, flying into the sky, a sword fell, like a thunderbolt tearing through the sky, the amazing lightning fell in the air, slashing towards the sword stele, and then, the sword was filled with a layer of golden luster containing amazing edges, and it was directly slashed on the sword stele.

Hit by the cyan wind blade, the sword stele immediately had an extra scratch, and then it was bombarded by the fireball, and with a bang, the sword stele shook and countless sparks splashed, all scorched black, and was impacted by the ice stream, and the frost spread rapidly, freezing the entire sword stele.

The thunder fell, and in the clicking sound, it bombarded the frozen sword monument heavily, and under the violent vibration of the sword monument, countless electric currents raged wildly, almost shattering.

The last sword, the sharp and boundless golden light slashed straight down, as if separating heaven and earth, directly cutting the sword tablet, shattering, and shattering into countless pieces.

Split the wind, the fire, the ice, the thunder, the iron!

The five human-level sword skills, under Chu Duan's repeated attempts, were combined in the most beneficial and convenient way for themselves, and the moves were connected, one move followed by the other, and the power was wave after wave, continuous attacks, and finally the damaged sword monument that had been attacked many times was completely shattered.

You must know that the original sword tablet can withstand many wind splitting attacks, even if it is damaged, it can continue to withstand at least ten attacks of the wind splitting sword technique, and under the combination of five different sword skills, it was shattered earlier, which shows that the power of the combination of five sword skills is stronger than the sword skills of the same level of ten strokes alone.

There were many fragments of the sword tablet under his feet, and Chu Duan exhaled a breath, and continued to retreat, one sword technique after another. It has been studied, more and more proficient, and the efficiency of researching human-level first-grade sword skills has also improved a lot, up to now, all the sword skills of the nine mysteries of gold, wood, water, fire, earth, cloud, wind, ice and thunder have been studied, but the sword skills of the mystery of emptiness have only made some progress, just a little skin.

In addition, Chu Duan also began to study the human-level second-grade sword technique.

A sword monument was erected again, and Chu Duan retreated a few meters. Staring at the sword stele, adjusting his breathing and qi and blood, his eyes flickered, and the momentum erupted like a volcano, and between the strong wind, an extreme edge erupted from his body, and Chu Du's pupils instantly swept through a cyan storm, and then the cyan turned into gold. Boundless sharpness.

All the momentum converged and condensed in an instant, as if it was integrated into the sword body, and one step out, the sword slashed. The cyan and gold colors converged on the sword body to form a unique blue-gold color, and the power of the mystery of the wind and the power of the mystery of gold were also blended together to form a new and more powerful force.

Chu Duan's body. With that sword, it cut through the sky, and a sword slashed towards the sword monument a few meters away. Under the extreme earthquake force, the space will be cut.

Very fast, like lightning, in the blink of an eye, a sword directly slashed on the sword tablet.

With a click, a corner of the intact sword monument was cut off, and it flew high and fell to the side.

The human-level second-grade sword skills that are blended with the golden wind and mysteries are really much more powerful than the first-grade sword skills, and the first-grade sword skills can only leave traces of up to four inches on this kind of sword tablet, but the second-grade sword skills can cut off a corner, although it is not big.

Landing on the ground and glancing at the sword in his hand, Chu Duan couldn't help but show a trace of regret.

This sword is the eight-sided Heavenly Desolate Sword, which has been used since it was forged by his own hands many years ago, and has accompanied Chu Duan in many battles and killed many strong enemies, which is very convenient, but now it is damaged.

I saw that there were several very clear cracks on the sword body of the Eight-Sided Heavenly Desolate Sword, which were in danger, and Chu Duan could see at a glance that the life span of this sword had come to an end, and it was destroyed from the inside, and even if it was repaired, it could not be restored to its original tenacity.

"It's time for a new sword. Chu Duan said secretly.

The eight-sided Heavenly Desolate Sword is the Wang Pin Sword Weapon, although it is the top, but Chu Duan has broken through to the Divine Condensation Realm, and what suits him should be the Imperial Sword Weapon, Wang Pin's sword weapon is gradually difficult to withstand the impact of the Sword Yuan of the Divine Condensation Realm, because the Sword Yuan of the Divine Condensation Realm is much stronger than the Sword Yuan of the Yuan Extreme Realm, a few impacts are nothing, and under the multiple impacts, the Wang Pin Sword Weapon will be damaged from the inside.

Especially after mastering the sword technique, the burden on the sword is greater, and the quality of the sword is not enough, so it is simply unbearable.

Chu Duan suddenly thought of the Divine Desolate Seed Sword Technique.

Perhaps, if you use the Divine Desolate Swordsmanship to plant a sword fetus for yourself, and when you grow up, you will have a blood-connected divine sword that can grow, and from then on, you will never need to change your sword weapon.

Thinking of this, Chu Duan inserted the damaged eight-sided Heavenly Desolate Sword into the scabbard and put it away, and set off to leave the small palace and go to the treasure house of the True Palace.

Showing the sword order of the Young Palace Master, Chu Duan had the right to enter the treasure vault.

The treasure vault seems to be located in another time and space, very huge, with the atmosphere of vicissitudes, and a very strong heavenly desolate essence permeating it, which is divided into various regions.

This place is usually rarely entered, and there are bans in each area, and it is a very powerful and esoteric ban, which can only be opened with the sword order of the Heavenly Desolate Earth Palace.

Sword area, elixir area, ore metal area, treasure clothing area, secret treasure area, treasure area, etc.

Chu Duan is the young palace master, his power is very great, and most of the things can be selected, but it does not mean that he can take all the treasures away.

The treasure vault is often one of the powerful foundations, even if it is the palace master of the Heavenly Desolate Earth Palace, he will only select a small number of treasures that have direct help for him to take away.

To cultivate the Divine Desolate Seed Sword Technique, a total of ninety-nine kinds of materials are needed, Chu Duan himself has fifty kinds, this time he plans to find the others in the treasure vault, and it is best to find the remaining forty-nine kinds.

After looking around, Chu Duan strode towards the ore metal area, all the materials needed for the Divine Desolate Sword Technique were basically ore metals, and only one was more peculiar, which made Chu Duan a little confused.

No matter, let's find everything we can find first.

Holding the sword order of the master of the young palace, he strode towards the ore metal area, the ban was useless to Chu Duan, and he walked into the ore metal area unimpeded, and immediately, there were many kinds of breaths, the strongest being the sharp breath of metal and the thick breath of earth.

Countless metal ores floated in the air, looking at the past, dense, like meteorite belts in the universe, one after another, some are very large, more than ten meters in diameter, some are very small, the same as fingernails.

Each metal ore floated in mid-air, motionless, as if time and space had been frozen.

On the surface of each metal ore, there was a layer of strange force fluctuations, and Chu Duan did not feel any danger.

There are too many, and at a glance, the area of this area seems to be endless, and the collection of metal ores also seems to be endless, as if it is a vast small universe with no end in sight.

With so much metal ore, Chu Duan's heart immediately became happy, maybe here, he could really find other materials for cultivating the Divine Desolate Seed Sword Technique.

The power of divine thought spread, instantly covering all the metal ores within a radius of thousands of meters, under the contact of the power of divine thought, Chu Duan immediately felt that the strange power on the surface of each metal ore intensified and fluctuated, and one by one the information naturally came into contact with the power of his divine thought, transmitted, and flowed into Chu Duan's mind, so that Chu Duan knew the names and characteristics of these metal ores, etc., which was more convenient for Chu Duan to find.

There are thousands of these metal ores, none of which is one of the forty-nine kinds, but each metal ore is very precious and rare in the outside world.

No matter how precious it is, it is useless, and it is useless if it is not needed, Chu Duan advanced thousands of meters, released the power of divine thoughts again, and continued to search.

The pressure in this place is relatively large, and the power of divine thoughts will be suppressed to a certain extent, and it is also a great burden to cover thousands of metal ores at one time and receive information on thousands of metal ores.

After sorting them out one by one, Chu Duan locked onto one of the fist-sized pieces of metal ore, strode over, and grabbed the metal ore in his hand, which was one of the forty-nine materials.

The first harvest made Chu Duan feel happy and continued to search.

The scope of this area is indeed very large, Chu Duan has been walking forward, he has searched more than a dozen times, and he still has no feeling of reaching the end, after more than a dozen searches, he has obtained a good harvest, he has obtained fifteen kinds of materials, and there are still thirty-four materials left to continue to search.

Look for it, this kind of search is a great burden on the power of divine thoughts, and when it is almost consumed, Chu Duan has no choice but to sit down and recover the power of divine thoughts, and wait until the power of divine thoughts is restored, and then continue to search.

In this place, there is no sky, no earth, the environment is unchanging, and the passage of time is not felt at all.

The twentieth material to start with......

25th material......

The thirtieth material to start with......

The 35th material to start with......

......

Finally, the forty-fifth material was started, and although it was very tiring, it was very happy in my heart.

"There are four more. Chu Duan said to himself, his spirits were uplifted, and after regaining the power of his divine thoughts, he set off again.

Keep looking, keep looking, forty-sixth, forty-seventh, forty-eighth, and the last one is left.

It's just that no matter how hard Chu Duan tried to find it, he searched the entire ore and metal area after the most lu, and he didn't find the last material.

I couldn't help but feel a little disappointed in my heart, and I quickly ruled it out, since I couldn't find it here, I could only go to other places to see.

"Heavenly Desolate Divine Flowing Golden ......" is the name of the latter material, and it is also the most important one among the ninety-nine materials needed to cultivate the Divine Desolate Swordsmanship. (To be continued......)
