Wu Yazi looked at Lu Xuan with a smile.

He knew that everyone had their own questions, but this matter was very important, even Wu Yazi and Tu Jiu had to keep their mouths shut, otherwise there would be endless disasters. So he was vague before, but he didn't know what Lu Xuan was going to ask.

It's a big deal, it's better not to answer.

And Lu Xuan said solemnly: "The disciple just doesn't know, why is the attack of the beast tide so regular, no more, no less, it will occur once every two hundred years?"

Everyone was stunned.

Wu Yazi moved his eyebrows and glanced at Lu Xuan deeply.

Everyone's questions before revolved around the origin of the blood demon and where the blood demon came from, but they didn't expect Lu Xuan to find another way to ask such a question. And Chu Wuye, Yun Ming and the others were reminded by Lu Xuan, and their hearts were also moved.

Yes, why do beast tides occur once every 200 years?

The origin and purpose of the blood demon were three thousand years ago, and there is no point in asking about it now, but the most important thing now is how to suppress the blood demon to prevent future troubles. Lu Xuan's question is the key, why does the blood demon only attack every two hundred years, there must be a reason for this.

Everyone's eyes were on Wuyazi.

Wu Yazi was silent for a moment, and then looked at Tu Jiu.

Tu Jiu nodded and said, "But it doesn't hurt to say it." ”

Wu Yazi got up and smiled at this time: "You go to a place with me." ”

Saying that, Wuyazi rolled up his long sleeves, and led everyone to the air, heading straight to the east.

In the blink of an eye, a dry riverbed appeared in front of me.

Lu Xuan's brain shook violently, pointing directly below, that is exactly the place where the golden needle has been pointing, according to Lu Xuan's guess, this riverbed should be the legendary treasure conceived by heaven and earth.

Wu Yazi's body was shocked.

Within a radius of dozens of miles, the heavens and the earth roared, and there was a white and misty breath enveloping the heavens and the earth, and Lu Xuan and the others felt as if they were in the vast ocean, and their bodies were cold. The terrifying thing is that there seems to be endless sword qi flowing between this heaven and earth, although it is formless and substantial, but it makes people's hearts thrilled, and they can't help but hold their breath.

Yun Ming was better, but he was also surprised: "Ancestor, this is ...... Limbo?"

Wu Yazi nodded and smiled: "As long as you cultivate to the realm of refining the Void and Merge Dao, you will comprehend the existence of the Void Realm, and my Void Realm is comprehended from the cultivation of the Ruins, so it is what it looks like." ”

Wu Yazi cultivated in the East China Sea and refined the Guiru Sword with three thousand heavy waters, and everyone in the Lingyun Sect knew about it. Lu Xuan listened to it beside him, thinking about whether he would return the Guixu Sword to Wuyazi later, Wuyazi has this fairy sword, and the suppression of blood demons in the future will also be like a tiger.

Rumble!

Lu Xuan was pondering in his heart, when the huge riverbed under his feet suddenly shook violently, as if hundreds of millions of long swords had penetrated into the ground, and the riverbed suddenly collapsed.

In the blink of an eye, the ground several feet thick was turned to ashes, and the sixty-mile-long riverbed suddenly sunken.

From below the riverbed, there was an astonishing glow rising into the sky.

Everyone couldn't help but be moved, looking down from the sky, through the bright light, they saw a huge building.

Under the riverbed, there is a white jade building lying horizontally!

It is a white jade building, divided into 12 layers, the shape is simple, like nature, each floor is full of five miles, and the total is sixty miles!

Bai Yulou was lying horizontally under the riverbed, looking at it coldly, but it looked like a huge pipe.

Everyone can see that there is a winding underground river flowing from the top of the white jade building, and then flowing out from the bottom, the underground river is like white jade, viscous like soup, exuding an incomparably pure heaven and earth aura, which makes people's hearts shake.

Twelve-story floor!

Lu Xuan exclaimed loudly in his heart.

The legend is really true, when the immortals came out of the forbidden land, holding the twelve-story building in their hands, calling it to imitate the treasure of the forbidden land, and the huge twelve-story building in front of him, isn't it the treasure of the heaven and earth in the forbidden land?

The golden needle became more and more excited, and almost broke out of its body.

Lu Xuan felt a sharp pain in the Mud Pill Palace, and his face suddenly changed drastically.

Wu Yazi didn't notice Lu Xuan's abnormality, but said in a deep voice: "Three thousand years ago, there was a spiritual river here, which passed through these twelve-story buildings, and the spiritual energy was tempered in every way, and it became extremely abundant. Therefore, this place was originally a holy place for cultivation, but since the blood demon rebellion three thousand years ago, which attracted a sword from the flying immortals outside the sky, this twelve-story building was seriously damaged, and it has lost its spiritual light. ”

"Although this twelve-story building is damaged, it is not completely destroyed, and it can still exude aura, and the ninth brother reluctantly urged the Burning Sun Bead with this aura to suppress the blood demon. ”

"However, this remnant spirit river will be on the verge of drying up every two hundred years, and the aura is less than one-tenth of what it usually is, so the power of the Sun Bead will also plummet, so that the blood demon can take advantage of it. ”

Wu Yazi looked at Lu Xuan and said with a smile: "Now do you know why the beast tide only occurs once in two hundred years?"

Before he could finish speaking, he suddenly frowned.

It wasn't until now that Wu Yazi found that Lu Xuan's face had become very ugly.

"What's wrong with you?"

Wu Yazi asked.

Others also noticed Lu Xuan's abnormality, and those present at this time were all the core people of the Lingyun Sect, Yun Ming, Chu Wuye and his wife, Ye Li and others, Chu Linglong and Zhao Wushuang and other senior brothers were also present, and everyone hurriedly gathered around Lu Xuan.

Lu Xuan tried his best to control the golden needle, and reluctantly smiled: "The disciple is fine. ”

However, he also knew that he couldn't hold out for long, and the golden needle obviously wanted to enter the twelve-story building, but he couldn't stop it at all, so he said to Wuyazi: "Ancestor, I want to go to the twelve-story building, okay?"

Wu Yazi was stunned.

"What are you going to do there? There are prohibitions in the twelve-story building, but it's not like you can go there. ”

Lu Xuan smiled bitterly, "The disciple really has a last resort, and he also asks the ancestor for help." ”

Wu Yazi was still hesitating, but Chu Linglong couldn't help but come to him and said: "Ancestor, Lu Xuan will never be untargeted, he should indeed have his reasons, and I hope that the ancestor will agree." ”

She had never seen Lu Xuan show such an expression, even after experiencing life and death in Tushan Kingdom, Lu Xuan had never shown such a painful appearance, so Chu Linglong was also a little confused.

Everyone begged, and Wu Yazi finally nodded and said, "Okay, but I can only take you in, and the others will stay outside." ”

As he spoke, Wu Yazi grabbed Lu Xuan's arm, and in an instant, he fell to the top of the twelve-story building.

"Don't leave me for a mile. ”

Wu Yazi told Lu Xuan with a serious face, and then took Lu Xuan into the twelve-story building.

Chu Wuye, Chu Linglong and the others watched the two of them enter the twelve-story building outside, looking at each other, and couldn't help but be a little confused.

Xiao Eleven insisted on entering this twelve-story building, what was it for?

............

It wasn't until he entered the first floor that Lu Xuan realized that the scene inside this building was far less peaceful than outside.

There was an extremely large suction force that seemed to pull Wu Yazi and Lu Xuan into the depths, but not only the whole person, Lu Xuan felt that his soul was shaking, as if even the three souls and seven spirits were about to be pulled out of his body by the suction. If it weren't for the fact that Wu Yazi released the void as soon as he entered the building, enveloping the surrounding void, Lu Xuan would have already been scattered.

"Why do you insist on coming here?"

Wu Yazi frowned and asked Lu Xuan, and there was accusation in his words.

He was originally very optimistic about Lu Xuan, but at this time, Lu Xuan's performance was like a naughty boy who didn't know the height of the sky, which made Wu Yazi a little disappointed.

Lu Xuan had calmed down at this time.

The golden needle also calmed down a lot, like a swimming fish shuttling in Lu Xuan's mud pill palace, as if it was "looking" at the scene in the twelve-story building.

Lu Xuan saw that Wu Yazi had the intention of blaming, but he didn't know how to speak, so he could only smile awkwardly, and instead of answering, he looked around.

At first glance, it feels familiar.

There are Taoist texts everywhere in the building, but the surrounding jade bibs are full of cracked marks, like broken jade bottles barely glued together, and those delicate and flexible Taoist patterns are also damaged. However, Lu Xuan had been cultivating in the three-story building for a long time, and the three-story building was originally the upper three floors of the twelve-story building, so just by looking at it, he confirmed that these patterns were no different from those in the three-story building.

The twelve-story building is extremely vast, and looking into the depths, it seems that twelve huge jade pipes are connected by a ring. There was a loud and dull sound of wind whistling in my ears, sounding like a dilapidated bellows, and like a terminally ill patient lingering.

Such a scene had never been seen in a three-story building, and it should be because the twelve-story building was destroyed by the sword intent outside that year.

At this time, the suction in the building suddenly stopped, and then the wind direction turned sharply, and a huge thrust roared from afar.

Breathing in and out, Lu Xuan was used to it when he was in a three-story building before.

However, Lu Xuan looked at the surrounding scene, and he was puzzled.

When Chengyun Ancestor explained to him the origin of the twelve-story building, he clearly said that the twelve-story building was conceived by heaven and earth, but Lu Xuan now seems that this is clearly artificially refined.

Why is the Golden Needle here?

Lu Xuanzheng was confused, but suddenly felt the "heart" from the golden needle.

He can now achieve simple heart-to-heart communication with Jin Zhen, and at this moment, Jin Zhen clearly hopes that Lu Xuan will take out the "replica" of the twelve-story building in the Xiyang furnace.

Although Lu Xuan didn't know what to do, he also knew that if he refused the golden needle at this moment, it would inevitably make waves, so he had no choice but to burrow into the soil furnace.

Seeing that Lu Xuan didn't reply, he turned pale several times, and then plunged into a small clay oven, so he couldn't help but be stunned. Although he knew that this thing was called the Furnace of the Soil, and he also knew that a small secret realm was sealed in it, he didn't know what the reason for Lu Xuan to enter the Furnace at this moment.

What the hell is this kid going to do?

Wu Yazi was confused, but saw Lu Xuan holding a crystal white jade tower in his hand and appeared in front of him again.

"This ...... Is it a twelve-story building?"

Wu Yazi recognized what was in Lu Xuan's hand at a glance, and couldn't help but widen his eyes.

He was trapped here for nearly two thousand years, and learned from Tu Jiu's mouth that a long time ago, there was a replica of a twelve-story building here, but it is said that this replica has already been divided into two, how could it appear in Lu Xuan's hands intact?

"Where did you come from?"

Wu Yazi couldn't help but ask in surprise.
