Peerless learning, which was once popular in the ancient road era, was either completely decayed or only in the hands of a very small number of people for various reasons.

The Dan Dao mastered by Zhou Xiao is a peerless science.

In order to save the Bone Dao people, he challenged the Heavenly Book Hidden Tower, but he accidentally comprehended the second mastery - Xuanlian Dao.

Xuan Lian Dao, in popular terms, is to refine Xuan Bing.

Weapons are divided into four classes, ordinary weapons, spiritual weapons, mysterious soldiers, and divine weapons. Among them, the spirit soldier and the Xuan soldier are divided into four levels: entry, small success, large success and peak.

The gods are ethereal and only exist in the myths and legends of the ancient road era.

And the weapon closest to reality is the Xuan Bing.

Even if it is ten peak-level spirit soldiers, it can't block the blow of entry-level Xuan soldiers.

The strength of the Xuan soldiers can be seen.

The core material of Xuan Bing is the liquid of adult demons.

Because it is too difficult to collect demon gangs, it is difficult to ascend to the sky, and the Xuan Lian Dao has almost been lost in the third-tier area and has become a peerless school.

The Tianya Emperor Sect left the inheritance of the Xuan Refining Dao, and he didn't want to waste the liquid he left in the underground of the Heavenly Eagle Academy.

Demon Gang is a rare treasure, and after fusing the Qinglong Demon Liquid, even after thousands of years, it can still ensure spirituality.

And once someone can penetrate the Heavenly Book Hidden Tower, they will get the Demon Gang.

......

Airplanes!

Two streams of spiritual light shot out of Zhou Xiao's eyes, causing resonance.

Not only the seventh layer, but from the first layer to the seventh layer, the entire seven-story Heavenly Book Hidden Tower reverberated and resonated!

White light poured out from the first and seventh layers at the same time, one from top to bottom, one from bottom to top, spreading like a tide, converging on the fourth layer, filling the entire Heavenly Book Hidden Tower!

The entire Heavenly Book Hidden Tower is glowing!

In the air, twisted waves appeared, as if energy was migrating.

However, the place where the real energy change takes place is the bottom of Longyin Lake.

......

At the bottom of Longyin Lake, a cyan dragon shadow was as fast as lightning, swimming towards the Immortal Killing Peak.

Before today, it didn't stop migrating for a moment.

The trajectory it traveled was from Longyin Lake Island to the Immortal Killing Peak Prison Cave, and then through the mountain peak, and it went around the Demon Prison Curse Valley not far away.

It's like a protective circle, guarding the Sun Martial Spirit hidden in the Demon Hell Curse Valley.

But today, its trajectory has suddenly changed.

It does not follow the trajectory of action for hundreds of years, year after year, day after day. After it burrowed into the prison, it did not climb over the mountain, but shot straight from the prison to the seventh layer of the Heavenly Book Hidden Tower!

Airplanes!

On the Dragon Seal Lake outside the Immortal Killing Peak, the phantom of the green dragon once again appeared.

Many disciples and apprentices saw the phantom of the green dragon, and shouted one after another, calling for friends.

However, the people of the Aquila Academy did not know that this was the last time they would see the green dragon on the lake again.

......

On the seventh floor of the Heavenly Book Tower, Zhou Xiao's heart was full of joy.

After breaking through the seventh floor and successfully breaking through, he was finally able to enter the prison and meet the Bone Painter.

As for the liquid, it was just a surprise.

Zhou Xiao was holding a copper box in his hand, the copper box was left by the Tianya Emperor, and the material was Tiantong, an extremely rare copper material that could be used to collect and release Gang liquid.

After contemplating the last Taoist treatise, Zhou Xiao already had more than sixty percent confidence in collecting the liquid from Gang.

There is no conflict between collecting the liquid and rescuing the Bone Painter, and for Zhou Xiao, it is a convenient task.

Airplanes!

The dragon's groans come from far and near!

Zhou Xiao pressed the martial seal with one hand, grabbed the box with the other, and his feet moved forward and backward, the blood energy was induced, and the power of the flesh was all opened, like a big tree rooted in the depths of the earth, immovable!

At the same time, ten veins flew out from behind his waist.

The pulse qi is like an arm, and it is like a whirlpool of the sun wheel, rotating in a circle, like a big windmill, ready to grab the copper box at any time to collect the qi.

This is the martial art used by the Tianya Emperor Sect in his life - "Thousand-armed Crazy Demon"!

During the heyday of the Tianya Emperor Sect, when he used this set of martial arts, the Dao energy turned into a thousand "arms", and he never ran out of air when collecting the gang.

Zhou Xiao just comprehended that the power he exerted was less than thirty percent, but it was enough.

Although he missed the Sun Martial Spirit, right now, he had the opportunity to collect the same immeasurable value of Gang liquid!

High-level bone beast companions, Xuan soldiers, and peerless beauties...... This is the desire of the top three in the hearts of the young monks on the mainland.

At this point, even Zhou Xiao is not exempt from vulgarity.

Airplanes!

The sound of the liquid is getting closer and closer.

Zhou Xiao was engrossed, his heartstrings tense.

A second later, a flash of blue light pierced the eye.

The cyan dragon shadow, from the other side of the air, opened a round door and flew into the tower room.

Zhou Xiao looked up, his gaze frozen.

In an instant, the expectation in Zhou Xiao's heart came to naught.

Born with luck, adventures and adventures, the Tianya Emperor, who has never missed in his life, miscalculated this time.

What flew from the bottom of the Dragon Seal Lake was not Gang's liquid...... It's a mouthful of Xuanbing!

Zhou Xiao raised his head and stared at the Xuan Bing who was dozens of meters long and looked like a cyan dragon: "Natural Xuan Bing......? For hundreds of years, it has been running underground according to the trajectory set by the Tianya Emperor. In just a few hundred years, how can the earth's leylines change so drastically, it should not affect it. ”

The refining process of Xuanbing, to put it simply, is nothing more than the fusion of Gang liquid with materials such as Tiantong and Tiantie.

Normally, this process is done by a metaphysician.

But in the magical nature of heaven and earth, there will occasionally be naturally formed Xuanbing - the liquid enters the ground and does not disperse, but under the influence of special energy, it attracts rare materials from the underground, fuses, condenses, and finally gives birth to natural Xuanbing.

A natural soldier with an independent spirituality, with terrifying aggressiveness and destructive power.

Most importantly, it is almost impossible to subdue. In the long history of the past and present, among the unverifiable legends, there are only a handful of emperors who subdue the natural Xuan soldiers, and in the end they all rely on luck.

The Tianya Emperor Sect did everything, but he didn't calculate that in just a few hundred years, the earthly vein structure of the Heavenly Eagle Academy was actually destroyed, causing the Qinglong Gang Liquid to become a natural Xuan Soldier.

"It must be artificial...... What idiot has nothing to do to mess around at the Aquila Academy!"

Zhou Xiao scolded.

The door to the prison has been opened.

Zhou Xiao didn't think twice and rushed to the prison where the Bone Painter was.

If it's a gang, it's easy to do, and it's easy to take it...... But now, Gangye has become a natural Xuanbing, and hope has basically been cut off.

He is not very old, but he is very resolute in his actions, and he can afford to put it down.

However, this time, Zhou Xiao had a trace of unwillingness in his heart.

That's a mouthful!

Most of the monks in the third-tier areas have never seen the Xuanbing in their lives! How many first- and second-tier powerhouses have been desperate for life!

When it flies out of the seven-story secluded tower and is exposed to the world, the thirty countries in the southeast, the third-tier region, and even the entire Dongzhou will go crazy for it...... However, he Zhou Xiao was the first person to meet it.

It was he, who visualized the Book of Heaven and comprehended the seven-layer Taoism, and opened the door.

It's him...... Let it come out!

If he doesn't try, he will look down on himself if he misses it like this.

Zhou Xiao jumped up in the air, his body swept towards the prison, but he used "Thousand Arms Crazy Demon" in mid-air, and the ten veins rolled up the copper box and copied towards the Xuan Bing!

Just try it once!

If it fails, it doesn't matter, at least he tried.

In any case, rescuing the Bone Painter comes first.
