Fortunately, Yang Yan passed on a method to him, using the power of the Void King-level refining furnace and the Instrument Spirit Firebird, and slowly refining the dragon bone dragon ball in the refining furnace.

The machine spirit has a mental connection with Yang Kai, and refining it is no different from Yang Kai's own refining.

This method does not require too subtle refining techniques, what is needed is just the accumulation of time, although there are some suspicions of shoddy production, but it is better than handing over to an unreliable refiner to refine and waste materials.

Even Yang Yan herself didn't have the confidence to use the Dragon Bone Dragon Ball to refine weapons, which was beyond her ability.

It can be said that this method is only suitable for Yang Kai, because he has a Void King level refining furnace, and he also has a spirit firebird!

Several years have passed, and this dragon bone dragon ball has also been completely integrated, after all, they are of the same origin, and it is not difficult to fuse, and now it is time to use it.

It's just that Yang Kai didn't expect that the first time he used it, he almost made an oolong, and the remaining dragon soul in the dragon ball was unwilling to give in to him.

Even if it is just a wisp of remnant soul and no sanity, it is also the remnant soul of the ancient holy spirit, and its nature is extremely proud, how can it be willing to surrender? Fortunately, Yang Kai has the secret technique of the living lotus, and at the critical moment, he forcibly suppressed the tenacity in the dragon soul, so there was no chaos.

However, this is not a long-term solution, and it seems that it will take time to concoct this dragon bone sword in the future before it can be used with peace of mind. Yang Xingxing thought secretly, looking around with cold eyes, and the smile on the corner of his mouth was as cold as a blade.

The terrifying coercion slowly dissipated. But everyone was in a cold sweat behind their backs, a breeze was blowing, and a chill hit their heads and feet.

Everyone thought that the Dragon Cave Mountain, which could be flattened and pinched at will, actually broke out with such a strong combat power at this moment, which was really unimaginable to them.

The psychic ancient tree, the stone giant, and this emerald green and strange long sword, which did not make them extremely afraid? Especially this emerald long sword, everyone knew that it must be a good thing, but no one knew how powerful it could exert in the Dao.

Time. Yang Kai was once again the center of attention. Many greedy and jealous eyes were fixed on the emerald sword.

Yang Kai also had the heart to try the power of his new secret treasure, so naturally he didn't want to waste time, and the Saint Yuan poured it into the emerald long sword, and a high-pitched dragon chant came out. The turquoise sword began to hum.

"Go!" Yang Kai pointed with his hand. A turquoise light suddenly flickered from his hand. Immediately, a behemoth with a body length of dozens of zhang suddenly took shape in mid-air.

It was a turquoise one with wings covering the sky and the ground. A strange creature covered in scales and armor that looks like gold.

The creature opened its bloody mouth, its teeth like swords and claws like spears, emitting a faint cold light that made people shudder.

"Ancient Holy Spirit!" Mo Yu groaned, and even with his city, he almost fell to the ground.

Although he had never seen the ancient holy spirit with his own eyes, Mo Yu was no stranger to this kind of creature, and almost every major sect had more or less records of the ancient holy spirit that had long been extinct, and Mo Yu naturally saw its pattern.

The behemoth in front of him was exactly the same as the record he saw, and it was clearly the image of the ancient Holy Spirit.

And it is also the top-ranked true dragon among the ancient spirits!

The momentum it exuded alone had already made the hands and feet of martial artists below the Void Third Layer Realm cold, not to mention the aggressiveness it possessed.

"There is also a remnant soul, he actually has a remnant soul of the ancient holy spirit!" On the other side, Fei Zhitu's eyes trembled violently, muttered, and stood in place stupidly, forgetting to entangle with his opponent.

Qian Tong is the same, their opponents are exactly the same, at this moment, who still has the heart to fight again, all of them have their eyes on the cyan dragon that is dozens of feet long.

The last time he was in the Imperial Garden, Fei Zhitu had seen an ice phoenix phantom, and he knew that Yang Kai had a remnant soul of the ancient holy spirit.

At that time, Fei Zhitu almost wanted to surprise Yang Kai as a celestial, and felt that his fate was really good, and he could actually have such a treasure against the sky, it was precisely because of this that Fei Zhitu changed his attitude towards Yang Kai, and did not dare to have the slightest attitude of relying on the old and selling the old, because even if it was just a remnant soul, as long as there was enough time and opportunity, it might not be able to grow into an existence that was not inferior to the Void King Realm.

It is better to bully the old than to bully the young, who dares to guarantee that Yang Kai will not be the person standing at the top of the pyramid in the future?

Forming a good relationship with him now will definitely benefit him in the future.

So this time Longxue Mountain was in trouble, and he ran over with Qian Tong without hesitation, and went around from it. Otherwise, with his personality of being afraid of trouble, how could he do such a thankless thing? He must have sat in the Heavenly Fortune City and watched from the sidelines.

He originally thought that Yang Kai could have an ice phoenix's remnant soul was already a chance against the sky, but who knew that he actually had a true dragon's remnant soul!

Moreover, this True Dragon Remnant Soul seemed to be more powerful than the Ice Phoenix Remnant Soul I saw last time.

Fei Zhitu was envious and jealous, and he was about to vomit blood.

Compared to Yang Kai's background, everything he has is scum.

Just when everyone was distracted, the cyan dragon had already pounced in front of a Thunder Tai Sect's Return to the Void Mirror, this martial artist had the cultivation of the peak of the Returning to the Void Realm, and he was only one step away from breaking through to the Returning to the Void Realm at the second layer, and his strength was not weak.

He had been fighting against the Divine Tree and the Stone Golem before, and he had been unharmed for such a long time, but he looked a little embarrassed, which showed how strong he was.

But no matter how strong the individual is, he can't face the ancient Holy Spirit directly.

Seeing the real dragon pounce, this person's face turned pale, and he hurriedly sacrificed a black gold shield, turned it into a protection, and guarded it in front of him.

The huge true dragon's eyes revealed a hint of humanized disdain, and one claw slashed forward, accompanied by a soft stabbing sound, and the shield was directly torn apart, as fragile as tofu.

Immediately, the cyan dragon opened its bloody mouth, and in front of everyone's eyes, it swallowed this Returning Void Realm martial artist in one bite.

The screams sounded, and soon stopped abruptly, and the breath of life belonging to this martial artist was annihilated in an instant.

When the body of the cyan dragon rushed past the position where the warrior was, a terrifying scene came into everyone's eyes, and there was only one skeleton left in the same place, posing as a defensive posture, but the flesh and blood on the bones had all disappeared.

The cold wind hit, and the crowd was like falling into an ice cellar.

Mo Xiaosheng, Cheng Pengxuan, Jin Shi, and Feng Pozi, all of them were as pale as dirt, and they were almost broken by the women surnamed Ye one by one.

After swallowing the flesh and blood essence of the martial artist of the Thunder Tai Sect in one gulp, the cyan dragon raised its head to the sky and let out a deafening roar, and then its big mouth opened again, and a turquoise mist sprayed out of its mouth, covering it downward.

More than a dozen Returning Void Mirror Warriors were instantly enveloped, and the screams came and went in an instant.

"Poisonous!"

"Get out of the way!"

The turquoise mist actually contained a violent poison, and the warriors who were enveloped in it were dizzy and difficult to breathe, and even the Saint Yuan could not function.

The ones with slightly lower strength staggered to the ground, and it was visible to the naked eye that their flesh and blood actually melted quickly, revealing Bai Sensen's bones, which looked shocking.

Only martial artists who have returned to the void two layers or more can fight their spirits and escape from the shrouded range of the turquoise mist, but their faces are also full of green energy, and it is obvious that the poisoning is not light, and it will take a lot of time and elixir to detoxify.

This cyan dragon is actually a poisonous dragon!

Yang Kai was also surprised, he didn't know what kind of magical power he had since he was alive with the body of the Dragon Bone Dragon Ball, and he also had the idea of trying it out at this moment, and now that the results had come out, he raised his eyebrows and was full of joy.

Among the true dragons of the Ancient Holy Spirit, the poison dragon and the fire dragon were the two most aggressive species, and this discovery naturally made him very happy.

Since the last time he buried Xionggu and his party, his only attack on the secret treasure Baiyue Tu blew himself up, he had no attack on the secret treasure to drive, first, he was full of confidence in his own means, and felt that there was no need to let Yang Yan refine anything for himself, because even if he refined the secret treasure, it would take a lot of time to recuperate.

The second and most important reason is that Yang Kai is waiting for the completion of the refining of this Dragon Bone Dragon Ball.

Now it seems that he did not expect in vain, the long sword secret treasure that has been refined by this dragon bone dragon ball is comparable to the void king level, and it seems that there is still a lot of room for growth, because after the true dragon transformed by the emerald long sword just now devoured the flesh and blood essence of a Returning Void Mirror martial artist, he clearly felt that the aura of his secret treasure was a little stronger.

This is clearly a sign that you can grow.

Just when Yang Kai was thinking about it, those few Void Mirror Martial Artists who had just escaped the shroud of the turquoise mist with their front feet, and their back feet were targeted by the stone puppets, they were lucky and their strength was not bad, but it also ended here, the Heaven Shaking Pillar waved, the heavens and the earth trembled, and no one fell together, and they all fell like wheat.

The smell of blood rose to the sky, and the entire Dragon's Cave Mountain became a Shura Purgatory in an instant.

The situation is strangely one-sided!

And it wasn't the wishful thinking that Zhongqiang had imagined to slaughter the people of Longxue Mountain, but they were slaughtered by them, and their morale was extremely low for a while.

Taking advantage of this opportunity, Chang Qi and others fought back to counterattack and seized the initiative at once.

Speaking of which, the strength of Chang Qi and the others is not very powerful, they only rely on the subtlety of the secret treasures in their hands, and those secret treasures are the virtual level high-grade secret treasures that Yang Yan tailors for them, and they are also the limit that a martial artist of their level can envoy.

Originally, they fought more with less, and the situation was worrying and stretched, so they could only use each other's horns and delay time.

Now the morale of the other party has plummeted, but Chang Qi and others are brave and unmatched, under the elimination of the other, the enemy began to retreat, Chang Qi and others did not rush forward, but step by step, not seeking merit, but seeking no fault, for a time it was also fierce, so that those enemies were angry but there was nothing to do.
