Not only must it be the same species, but the species itself is also particular.

For example, the spirits of a large number of hares and pheasants in the demon tide are not looked down upon by Zhang Yan. The traditional way of direct absorption of the divine soldiers has the dragon soul and tiger spirit, if only use some small animals that are not special, I don't know how to be called the spirit of the soul, he can't afford to lose that face!

"The dragon and snake have nine changes, and the most suitable one to ride the yellow sword is, of course, the dragon. But dragon species are hard to find, there are a lot of snakes here, so use snakes!"

The flying sword "Chenghuang", which had accompanied Zhang Yan at the beginning, appeared silently, slid along the surging demonic qi inside the demon tide, and stabbed a serpentine spirit more than ten meters long.

The primitive size of these spirits was not so large, they could grow to more than three zhang, and they were also annexed many times. However, being able to become such a large body and still retain the characteristics of the previous life is equivalent to the spirit itself being absorbed and digested.

It is definitely different from Zhang Yan's own use of a variety of spirit sacrifice flying swords.

was stabbed by "Chenghuang", and the action of the long snake spirit stopped. Without waiting for the other spirits around him to react, Cheng Huang Jian had already brought back the long snake spirit.

Zhang Yan took it, released the true yuan, and wrapped the Chenghuang Sword with the spirit for sacrifice.

After the first sacrifice, "Chenghuang" became more active. Coming and going, slashing the spirit and soul are innumerable.

You need to choose an object, and there are not many spirits that can be used for cultivating, and the speed is slower than when you are refining "Four Looks".

The previous Sigu Sword was transformed by slashing. If it weren't for Zhang Yan's pickiness, the type and quality of the spirit he killed would actually be pretty much the same, not much different.

But "Chenghuang" is different!

The quality of the spirit directly affects the effect of the flying sword, and Zhang Yan didn't dare to be careless, and his speed was much slower.

Since he decided not to deliberately look for islands and reefs, Zhang Yan flew as he pleased, chasing the spirit he needed in the demonic energy. Gradually, it was discovered that the intensity of demonic qi in the tide was actually very different, and there were even blank areas without demonic qi at all.

It took four times as long to refine the "Four Looks" before Zhang Yan stopped chasing the spirit.

There are also limits to the use of direct absorption. Feeling that the "Chenghuang" had reached its limit, Zhang Yan stopped, and stretched out his fingers with his horizontal sword.

"Hum~"

"Cheng Huang" shook and roared, and the pure dark power emanated, forcing back the surrounding demonic energy.

Until now, Zhang Yan has gradually distinguished more differences between the demonic energy and the dark power in his body.

The demonic energy is chaotic and changeable, but the dark power can give him a feeling of "refinement". The same tendency is to be shattered and ended, how to make a difference, Zhang Yan can't understand it, but he can experience the difference.

After a long period of contact with demonic energy, his understanding of dark power has become deeper, and he has also developed a new understanding of "Dragon and Snake Nine Changes".

Heaven is lacking, heaven is extinguished, heaven is absolute, rebellion, moon desecration, thoughtlessness, six poles...... The Black Sun Demon Lord seems to borrow the power of an otherworldly "flying lizard" every time he changes, and he has also recovered according to the power of each dragon warrior he remembered in his previous life.

Now I find out that it is not!

From beginning to end, the Black Sun Demon Lord only built two powers, the Dark Dragon and the Three-Headed Golden Dragon, in the Jade Jane!

"I thought that the information sensed by the Black Sun Demon Lord was incomplete, and it was completed and reconstructed according to the memory, but now it doesn't seem to be all wrong, but it is also a snake to add!"

The route constructed by the Black Sun Demon Lord, the first to the seventh change, from beginning to end, is from the devil to the Tao! In essence, it is Tai Chi! It is Yin and Yang!

"Whether the Demon Lord knows it or not, he doesn't actually plan to use it. A dark dragon and a three-headed golden dragon happen to be the two most extreme dragon warriors in the book, but I'm afraid it's not a coincidence! The others are either derivatives of the dark dragon, or the precursor of the three-headed golden dragon, and the seven dragon warriors in my memory are wrong!

"I have always felt bad when I entered the fourth change, but I am afraid that there is also this reason!"

Zhang Yan exhaled softly.

"I've never transformed multiple bloodline powers!

"From the devil to the Tao, the yin and yang are born, peel off the skin of the other world, and leave the bones of this world, so it doesn't matter if you practice until the 'six poles', or transform the 'heavenly absolute' by yourself, you are completing the transformation of Tai Chi Yin and Yang. Well...... The same cannot be said of it!

"Let me transform the 'Heavenly Absolute by myself', the power will definitely not be as good as the 'Six Extremes' left by the Demon Lord!"

Although the Black Sun Demon Lord only left five changes before, it was in terms of the exercises that could be cultivated. For the important anchor point of the "Six Poles", and the subsequent confluence of the Demon Dao, Yin and Yang were mixed, there were already a lot of ideas back then.

The "six poles" restored on this basis are not comparable to starting from the "heavenly absolute" and starting from scratch.

A smile of comprehension appeared on the jade face, Zhang Yan let out a long laugh, and his body suddenly lost support, fell freely, and fell towards the sea.

With the sound of the yellow sword, he flew towards him in hot pursuit. The loop in the air is inserted straight into the heart from the chest. The strange thing is that the three-foot long sword did not reach the handle, and I didn't see any part of it stabbing out from behind and penetrating the body.

Bright red blood flowers poured out from the wound where the sword had been inserted.

The moment Zhang Yan fell into the water, one after another pure dark power overflowed, turning into thousands of threads and cocoons to wrap his body.

Grunt~

The giant cocoon ball sinks until it touches the bottom of the sea.

Thick tiredness rises.

Zhang Yan yawned and fell into a deep sleep.

......

Sleep, wake up, wake up, sleep.

It took only four days for the fifth cocoon transformation to form a cocoon, and it only took sixteen days to practice the sixth transformation "no thought". The short time of these two cocoons was beyond Zhang Yan's expectations.

"The cathode is born, the magic elimination path is long, from the fifth change is a new beginning, and the time is not getting longer and longer!"

In hindsight, the truth is quite simple, but it is even more difficult to make a judgment in advance.

Fortunately, this time the time of the transformation was miscalculated, which is not a bad thing, but a good thing. Originally, he only planned to take the time to complete the fifth change, but now he has practiced the sixth change together, which can be said to be an unexpected joy.

A black and golden sword light rushed to the sea.

"No thoughts!"

The flying sword is in the sky, and within hundreds of feet around, all the spirits and monsters are all unable to move, and under the staggered sword light, they turn into large pieces of flying ash.

Even energy has a tendency to be decomposed by sword light. The demonic qi, which had already thinned a lot, and the other attribute heaven and earth vitality that had been replenished, were consumed and decomposed in the vibrating sword light.

Zhang Yan even felt that he could freely transform these decomposed energies into arbitrary attributes.

"Mamoto Yayama!"

With his thoughts, a Zhenyuan of Jiashan that was no different from Zhang Yan's cultivation before appeared beside him. The number is also similar to that of Zhang Yan when he first crossed over, which is very touching.

Zhang Yan gasped slightly, adjusting the breath in his body. At that moment just now, the consumption of the true yuan was seven or eight out of ten, and the physical and mental consumption was very serious, in exchange for only less than one-tenth of the consumption of the true yuan of the mountain.

Consumption and output are not cost-effective.

"The use of 'no thought' represents a lot of significance, but it's not suitable for combat, at least not yet......

At the same time, a feeling surged in Zhang Yan's heart: "'Moon Blasphemy' triggers the inner emotions of others, and 'no thought'...... There is no thought, no thought, and the same focus is on the spirit. These two become one and two, two and one, similar but not the same. Then, from this past, to the 'six poles', it is a brilliant new era. ”

The more advanced the technique, the more points are consumed. The fourth change of the "Dragon and Snake Nine Changes" is upward, and the number of points required for each change is astronomical.

Before, he had added "Moon Blasphemy" to "Out of the Spirit, Don't Go Out of the Cardinal", and now he only upgraded "Wuxiang" to "Dacheng Consummation, Collect and Release Freely", the points that have accumulated for a long time before, have consumed seventy-seven-eighty-eight.

"I thought that the days of shortcomings were gone. I didn't expect it to be spendable, it seems that I still have to do big things if I have the opportunity, and it's good to save more points!"

Zhang Yan's body flew up, the color was pure black, but it also gave people a bright and crystalline feeling, and the flying sword that radiated a metallic luster, like a swimming dragon, pursued the place where the demonic energy was rich and fled.

This wave of magic is almost over.

On the surface of the sea, the concentration of demonic qi was greatly reduced compared to before his sixth cocoon. A lot of blank areas appeared, and instead of them, a large number of other attribute auras that had been polluted by demonic energy appeared.

In the underwater sky, normal creatures other than spirits are also beginning to appear. The difficulty of finding the Desirable Spirit has increased dramatically compared to before.

It took more than two hours, flew two or three thousand miles west at high speed, and after catching up with the tail of the demon tide again, Zhang Yan gathered all the spirits needed for sword refining.

The dragon and snake have nine changes, the dragon's blood has turned into a cocoon, and the weapon has been integrated into the body.

This method is somewhat the same as that of the natal divine weapon that was sacrificed after the completion of the Jindan Dacheng. The same thing is that the magic weapons and weapons are collected into the body for warmth, and over time, the cultivation is improved, and the quality of the magic weapon of the flying sword can also be improved.

The difference is that the magic weapon of Dacheng Jindan is collected into the dantian, and together with Jindan, it is constantly warmed and tempered by the true yuan, while the dragon's blood cocoon is to insert the weapon into the heart and brush it with blood pulses.

After completing two changes in a row, the biggest improvement is not actually his own physical strength, nor is it the true dragon bloodline that has been greatly strengthened, but the flying sword "Chenghuang" that he chose to temper with the "Dragon and Snake Nine Changes"!

Before getting "four looks", there was no reluctance in my heart. Zhang Yan was no longer entangled in the appearance of the Yellow Sword, and he could no longer interfere.

After two transformations, the appearance of "Chenghuang" has changed greatly. Color, shape...... The blade of the sword grew by three inches, and the blade of the sword narrowed by more than half, becoming more sharp and sharp, like a sharp long needle.

Before the fifth cocoon, Zhang Yan used the method of collecting spirits in advance, and raised the "Chenghuang" to the limit. After just four days, the body completed its fifth transformation, and the Yellow Sword was also like a regular recuperation for decades, not only did the quality improve again, but at the same time, the danger of collecting the essence refining upgrade was also reduced, and it was lowered to a relatively safe area.

Concocted in the same way, the sixth time broke out of the cocoon, and "Chenghuang" was already a sixth-order flying sword.

The spirits that can be captured in the Demon Tide have little effect on the Yellow Sword.

It took half a day of hard work and hard work, and only raised the "Chenghuang" from the sixth order to the level of less than the sixth order.
