Xiao Yan's face was also solemn at this time, and he was secretly running a fighting spirit. After fusing the poison pill with different fires, combined with the method of ascension, the poison pill can reach the rank of eight grades, which is what Xiao Yan had expected from the beginning.

After all, the original poison pill method has reached the peak of the seven grades in terms of materials and refining methods.

Using the alien fire as medicine is the madness that Xiao Yan thought of through the incineration technique, and he could constantly devour the alien fire to improve himself.

Ordinary alchemists can get a kind of alien fire, thank God, and it is simply crazy to worship it as an ancestor and use it for alchemy.

It's just that what Xiao Yan didn't expect was that his alien fire poison pill had perfectly cracked the doom poison body, but it made this god unhappy.

In the face of the eight-grade colored Dan Lei, Xiao Yan was still a little mentally prepared, but the gray Dan Lei of the Forbidden Dan had a little headache.

Although the Venerable of the Forbidden Pill Pill did not leave it to Xiao Yan in the Acceptance Ring, it was mentioned in ancient books that whenever the refining of some pills harmed the heavens and harmed the reason, it would attract this gray Dan Lei.

The power of this kind of Dan Lei will not change, according to Xiao Yan's estimate, the Alien Fire Poison Pill after the ascension should normally be a four-color or five-color Dan Lei pill.

The most dangerous thing about Gray Danlei is that it doesn't have a number of times. This kind of Dan Lei is similar to Heavenly Punishment and Heavenly Punishment, and he will not give up until he destroys the alchemist and the pill!

Xiao Yan turned his head and glanced at the little medicine immortal who was still sitting cross-legged, the Alien Fire Poison Pill had been completely refined, but what would happen, even Xiao Yan didn't know.

"The little medicine fairy is quite suitable for wearing an alchemist's robe." Xiao Yan smiled, thinking of the little medicine fairy's dream of becoming an alchemist, but he didn't have the talent of an alchemist.

Boom Boom! At this moment, the gray thunderclouds in the sky finally couldn't stop it, and suddenly cracked down a bolt of lightning, this lightning was as thick as a mountain range, if it was cracked, let alone the entire library, I am afraid that even the entire space would be destroyed in an instant!

"Eight Pindanlei!"

"Douzun's attack!"

The faces of the two elders changed greatly, this is an eight-grade Dan Lei, and the power is equivalent to an ordinary Douzun blow!

Although they are already half-step Douzun, the gap between half-step Douzun and Douzun is still very huge, even if the little medicine immortal has such a physique as the Doom Poison Body, it is impossible to overstep the level to defeat the Snake Emperor who has just entered the Douzun.

Buzz Buzz !!

At this time, the ground of the entire inner courtyard lit up with regular rays of light, and all the elders stood on one node after another. Even Wu Hao, Hu Jia, Xiao Ning and Xiao Yu also contributed their own strength.

"Mille-Feuille Guardian Array, activate!"

Great Elder Su Qian let out a loud shout and stood in the middle of the formation. This is the guardian formation left by the mysterious dean, when the Falling Heart Flame broke out, Su Qian joined forces with many inner elders to form this formation, otherwise Xiao Yan and Cai Liang would not be able to subdue the Falling Heart Flame.

Both Android and Apple are available. 】

With a buzz, countless fighting qi finally condensed into an immortal mirror and appeared in the sky above the library pavilion, and the fairy realm fell with endless light, turning into an incomparably powerful defense, blocking this heavenly thunder tribulation for Xiao Yan!

Su Qian and the others all trusted Xiao Yan and knew that Xiao Yan would definitely not refine that hurtful elixir!

Rumble! The gray thunder and lightning bombarded the immortal mirror heavily, and to everyone's surprise, the guardian array left by the dean actually blocked the gray Dan Thunder this time.

"Blocked!!"

"No, look!"

Kakaka's sound suddenly came from the sky, and the guardian formation that had originally condensed the fighting spirit of all the powerhouses in the inner courtyard and was laid out by the dean himself began to appear petrified visibly!

In just a moment, the radiant fairyland lost all light and turned into a stone! With a bang, the gray sky thunder instantly shattered the formation of the entire inner courtyard.

Xiao Yan's eyes narrowed slightly, this gray heavenly thunder was even more terrifying than he imagined. It's not just power!

The gray Dan Thunder contains a terrifying power of death qi, when it is touched by this power, no matter what kind of cultivation it is, even if you are a Dou Sheng, your muscles will age in an instant, and you will suddenly age more than ten years old.

will be robbed of life!

If you fight with a fighting spirit at this time, no matter how powerful the fighting spirit is, once it is touched by this terrible power, it will be corrupted all at once, and no matter how much fighting spirit you have, it will be corrupted until you become a dead person.

After all, refining the forbidden pill is not allowed, so if there is a Dou Sheng, wouldn't it be able to refine the forbidden pill unscrupulously?

How could God allow such a thing to happen, so the Gray Heavenly Tribulation can not be resisted by strength at all, any power will be deprived by that gray, just like the original color of Dan Lei, naturally including human life!

The formation was broken, and Great Elder Su Qian was the first to bear the brunt of the backlash, and suddenly spit out a mouthful of blood, and sighed: "Alas, Xiao Yan, the rest depends on your creation." ”

Seeing the power and terrifyingness of the gray heavenly tribulation, the eyes of the two elders also revealed perseverance, the eyes of the two condensed, they took a step together, glanced at each other, and two pairs of dry palms slowly poked out of the sleeve robe, slowly moving with strange seals.

With the actions of the thousands of elders, a series of violent spatial fluctuations suddenly diffused out from the two of them, and with the fluctuations of this space, the space of that piece also became distorted, like countless folds, it looked crooked, and the line of sight was directly distorted.

The two of them together are no less than Douzun!

With a buzz, the entire library suddenly burst into a strong light, and the entire library seemed to have become a delicate pagoda at this time, and the whole body was shrouded in a special light.

The space lock of the entire library is locked in an instant!

The Library Pavilion is the most important place in Canaan Academy, and the protection here is also the most powerful!

A booming gray heavenly tribulation roared, and in an instant, the entire library pavilion shook violently, blocking the first blow!

Blocking a gray heavenly tribulation, the thundercloud seemed to be angry, and there was a loud bang again, and the thunder suddenly set off the spatial turbulence with a momentum of ten thousand pounds, like a stormy wave, and even shattered the entire space lock at once.

Xiao Yan, who was standing in the library pavilion, exerted his strength slightly, and clenched the Xuanzhong ruler, he knew that the only way to solve this dead end was to solve the thunderclouds in the sky.

That thundercloud contained countless gray death powers, and any fighting skill that touched that thundercloud would immediately be petrified, corrupted, and decomposed into the power of heaven and earth, and it was impossible to break the thundercloud at all.

But Xiao Yan has a chance!

None of his fighting skills could touch the thundercloud, he could! Because he also has a strange fire! And there are eight more!

The power of that thundercloud is similar to the death flame of the Yin and Yang Twin Flames, if Xiao Yan is now a Dou Sheng, maybe only the Yin and Yang Twin Flames can solve that thundercloud.

But if you want to rush into the sky, the slightest carelessness will be the end of ashes.

"Xiao Yan! The protection of the library is about to be irresistible! At this time, Qian Lao's voice sounded from Xiao Yan's heart, and the crystal clear protective light film of the Library Pavilion also became dim.

"If it really doesn't work, then self-destruct the elixir!" Bai Lao's hurried voice also sounded at the same time.

To be able to withstand such a terrible two blows, the protection of the Library Pavilion is already the limit! Even if the Heavenly Fire Venerable was here, it was estimated that it would be difficult to resist the two blows.

"Thank you for the help of the two elders and the elders of the inner courtyard, Xiao Yan is grateful." After finishing speaking, Xiao Yan's handprint knotted, the back of his shirt was instantly broken, and a pair of domineering and incomparable, flashing bone wings appeared behind Xiao Yan.

With a movement of his mind, he cast the Three Mysterious Transformations of Heavenly Fire, and the eight colors of different fires broke out of his body, and instantly returned to Xiao Yan's body, rampage along its meridians, and a momentum that reached Dou Zong suddenly burst out from Xiao Yan's body, and the momentum was still rising.

This is Xiao Yan's first time since he fought against Lingquan, he has once again used all the different fires to cast the three mystical transformations of the heavenly fire!

The terrifying power of the alien fire made Xiao Yan's whole body tear and pain.

This is obviously not enough, one by one the seven-grade pills seem to be free of money, all poured into the mouth, the Imperial Power Purple Pill, the Returning Life Pill, the Great Dragon Power Pill, the Grandmaster Huiqi Pill and other pills that can temporarily improve the strength are all swallowed into the stomach at one time, turning into a fierce medicinal effect that fills the whole body.

In Xiao Yan's dictionary, there are no two backs!

At this time, the eyes of the thousands and two elders outside were shocked, and under the bombardment of the third gray heavenly tribulation, it was only half a sound, and the guardian of the library pavilion that could resist Douzun's attack was actually shattered, and even the space lock was cracked to pieces!!

"Flame Eater Ruler!!"

A loud shout came from the library pavilion, and in an instant, an astonishingly huge eight-colored ruler burst through the sky like lightning, and everywhere along the way, the slight overflow of energy directly caused the space to be torn apart!

Although the Flame Devouring Wave Ruler is only a low-level fighting skill of the ground level, this is a fighting skill that Xiao Yan has cultivated to the Great Perfection in a small number, and it also has eight different fires attached!

There was even a thundercloud-sized flame devouring wave ruler in the sky, and in the surprised gaze of the thousands of elders, it collided heavily with the gray thunder and lightning.

Rumble!!!

Two extremely terrifying attacks, like a meteorite colliding!

To the surprise of the thousand and two elders, the gorgeous and colorful fire was not robbed of color by the power of gray!!

The power of alien fire cannot be taken away or erased even by heavenly punishment!!

Because the alien fire is also the strongest force in the birth of heaven and earth!

The two clusters of energy expanded rapidly, and at the end, the points of light became more and more dazzling, and the fluctuations in that space also became more and more violent at this moment, and the terrifying explosion exploded in mid-air, forming a strange energy ball.

On one side is a brilliant and colorful color of different fire, and on the other side is a thunderstorm without any color.

At the moment when the two energies were annihilated, there was a pop of breaking through the air, and after the cultivation was improved, Xiao Yan's speed of three thousand thunderbolts and bone wings was no less than the speed of Douzun, turning into a shadow of a mold lake, and he rushed towards the thunderclouds in the sky without his life!

"Xiao Yan!!"

"Could that be Senior Xiao Yan!!"

Seeing Xiao Yan's figure flying out of the broken space lock, many sharp-eyed people exclaimed!

"Senior Xiao Yan, what is he going to do?!"

"He's going to rush into that thundercloud!"

Seeing this scene, Xiao Yu clasped his hands, and his eyes were full of worry: "Xiao Yan, you have nothing to do." ”

"I don't care if you're really God or pretending, today, this Dan, I Xiao Yan want it to happen!!" Xiao Yan roared wildly, and in this instant, his soul was completely released, and a terrifying dark soul power once again enveloped Xiao Yan's body!

Xiao Yan incarnated as Shura again!

"Asura!"

Unlike last time, this time Xiao Yan's soul realm was already a spirit realm!!

This time there is no support from the soul power of the Heavenly Fire Venerable, but Xiao Yan's own soul power is already different from what it used to be!

The soul power of the spiritual realm all exploded, the third form of the Shura Soul Slaying Technique was launched, and Xiao Yan's cultivation once again rose up like crazy!! Relying on the triple ascension of elixir, alien fire, and soul power, Xiao Yan's cultivation was unexpectedly raised to the terrifying realm of the Nine Star Dou Sect!!
