"Bang dang!" A heavy muffled sound came, and the tower door that had been closed for an unknown number of years finally opened slowly under the condition that the demon sky broke these sigils, and there was some inexplicable color flashing in it.

Dusty, a smell of decay, gradually spread......

"This soul tower is similar to the crystal that tested your spiritual power when you participated in your family's clan competition, but this soul tower tests the purity of the soul power of the warrior, the higher the purity, the greater the chance of getting a better servant corpse. ”

Looking at the open tower door, the light in Mo Tian's eyes flashed, as if he could see through the origin of this soul measuring tower.

Hearing this, Ao Shuang nodded.

The test crystal at the time of the clan comparison was used to test the realm of martial artists' cultivation, and the effect of this soul measuring tower was much the same.

"The prohibition on this tower gate has become no longer strong after the baptism of the years, otherwise it would not have been broken by me so easily. But what worries me is whether this teleportation array can still be activated now......" Mo Tian frowned, and after giving Ao Shuang a look, he walked in with the latter.

Entering the Soul Measuring Tower, Ao Shuang found that the space inside was very large, and there were no stairs connecting the top, until the top of the tower, it was still unusually empty. The top of the tower was always shrouded in a layer of mist, making it difficult to see even the arrogance of cultivating the goshawk's pupil.

In the center of the Soul Tower, a strange crystal floated in the void, exuding bursts of strange aura.

"I also knew by chance that in this ancient battlefield in the Northern Regions, every thirty years, the Servant Sect would meet once in the present. It's been a bumpy road...... "Mo Tian smiled bitterly, after Ao Shuang entered the ancient battlefield, he almost died several times. And in those moments of crisis, some of them couldn't even take action themselves.

Just like the Nine Dragons Monument conjured up in the Nine Dragons Heaven Destroying Tribulation, the Demon Heaven will definitely break Ao Shuang's spiritual method, and it is very likely that it will not only be a question of whether Ao Shuang can successfully comprehend the spiritual law, but an improper one, and may fall directly.

You must know that there is no room for any disturbance during the tribulation, and if the Demon Heaven intervenes, it is very likely to enhance the power of the Heavenly Tribulation.

"At the top of the Soul Tower, a large amount of spatial power is condensed, and the higher the purity of the soul, the more spatial power it can pull. At that time, a spatial door will be formed, and I don't know where to enter through this spatial door. However, as long as you enter that space door, you will definitely be able to obtain a powerful servant corpse......"

After a pause, Mo Tian continued: "Your soul power may be purer than my soul after being tempered by the magic bead, that is to say, your chances of obtaining the strongest servant corpse are even greater than mine. However, I can't force intervention at this time, so it's up to you to ...... all this."

After saying that, Motian paced to the crystal, and slowly raised his hands and pressed them on the crystal.

"Bang!" When Mo Tian's hands pressed on the crystal, the crystal suddenly began to tremble, and the entire soul tower shook violently, and then the top of the tower instantly surged up, and bursts of roaring sound came out.

"Huh!" A white pillar of light suddenly burst out of it, enveloping the entire person of Motian like a waterfall flowing down, and Ao Shuang found that this pillar of light contained some kind of strange light points, swaying around Motian's body.

These points of light, flickering with a white halo, were testing the purity of the Demon Heaven's soul.

After about ten breaths of time, the pillar of light faded away. And those points of light also slowly converged around the Demon Heaven, gradually condensing a door-shaped phantom, and the door flashed with colorful spiritual light, and I don't know where it leads.

Mo Tian saw that the space-time gate appeared, and slowly walked over, just when he was about to walk into it, his body was stunned, and he turned to look at Ao Shuang: "Boy, I went in first, I don't know what's inside, you should be careful for a while......"

"Hmm. Aoshuang responded.

After Mo Tian finished speaking, he walked into the space-time gate, and after a burst of virtual light flickered, Motian and the entire space-time gate disappeared. Seeing that the demon sky entered it, Ao Shuang didn't say anything, but returned to the source of ten thousand crocodiles.

At this time, in the source of ten thousand crocodiles, Yi Lingxin and Han Ziye frowned, and at this time, a burst of void flickered around them, and then, the arrogant body shape change gradually revealed from it.

"Brother Ao (brother)!, what's wrong with you?" Seeing Ao Shuang appear, the second daughter was happy at first, but then, she saw the hideous wound on Ao Shuang's arm, although it had been scarred, but it was still a little terrifying at first glance.

Looking at Ao Shuang's breezy look and the scar on his left arm at this time, tears appeared in the eyes of the second daughter. Although the two of them don't know what Ao Shuang has experienced, it must be a very thrilling and dangerous situation to be able to hurt Ao Shuang.

"It's nothing...... Ao Shuang shook his head, and then looked at the second daughter solemnly: "The current situation is ......"

Next, Ao Shuang told the two of them about the Soul Measuring Tower and how to do it. After listening to Ao Shuang's words, the second daughter was even more moved, and by Ao Shuang's side, the two of them seemed to be specially choosing cheap ones.

"Now is not the time for ink...... Looking at the tears in the eyes of the second daughter, Ao Shuang can guess something, but now is not the time for children to grow up, put his hand on the shoulders of the two, and the figure gradually disappeared in the source of ten thousand crocodiles......

Outside, the three of them appeared in the soul tower, and then their eyes looked at the crystal ball floating in the air.

"Ziye, you come first. Ao Shuang took his hand back from the shoulders of the two, looked at Han Ziye and said, as a soul mutant, she may have some unexpected gains.

"Hmm. Han Ziye nodded, she also knew that a few people were in the servant sect now, and it was not the time to hesitate. Under the gaze of the two, he came to the crystal ball, stretched out his white hands and put them on the crystal ball.

"Hum!" was about the same as the situation of the Demon Heaven, a buzzing sound came, and the spatial power at the top of the tower made a trace of waves again, but there was no majestic movement caused by the Demon Heaven, and then a pillar of light shot down, enveloping the cold purple leaves.

However, this time, the points of light in the pillar of light were different from those of the Demon Heaven.

The points of light in the pillar of light that shrouded the demon sky were pure white, emitting bursts of white halos. But the light spots around Han Ziye's body were black and white, and the halo also revealed black and white.

This should be the strangeness of the soul mutant, right?Ao Shuang looked at the black and white point of light, and thought to himself.

......Ten breaths later, a black and white space door formed beside Han Ziye, and after the former saw this scene, he didn't make any moves but turned to look at Ao Shuang and Yi Lingxin.

"Go inside, be careful yourself. Ao Shuang smiled and nodded, and Yi Lingxin's eyes also crossed a look of encouragement.

"Hmm. Han Ziye nodded obediently, and then under the gaze of the two, he walked into the space-time gate. After a burst of void flickering, the figure of Han Ziye gradually disappeared into the space door.

"You start too, be careful, in fact, I don't know what's in it......" Ao Shuang looked at Yi Lingxin tenderly, whenever this kind of time, he could remember that when he encountered misfortune, this woman stood up and stood in front of him.

It's like Liu Ge, outside Qingyun City, blocking Duan He's attack for himself.

This kind of behavior made Ao Shuang extremely moved, and he will never forget it for the rest of his life.

"Brother Ao, you should be careful for a while......" Yi Lingxin knew that Ao Shuang's system was strong, and the wound on her left arm might not have any effect on her, but she was still very worried about Ao Shuang and didn't want him to suffer any more harm.

"Don't worry. Aoshuang nodded.

It is the same as the situation of the cold purple leaf, the only difference is that the light spots in the pillar of light are black.

Seeing that Yi Lingxin also disappeared into the space gate, Ao Shuang let out a long breath. From the fact that the three people of Demon Tian, Han Ziye and Yi Lingxin passed the test to enter the space-time gate, Ao Shuang saw something.

The purity of the soul power of the three people, although Ao Shuang didn't know the specific situation, but Ao Shuang could guess some approximate ones.

As a saint-level powerhouse, Mo Tian's soul power is naturally much stronger than Yi Lingxin and Han Ziye, this kind of strength is not to say that it is strong to a strong degree, but it is powerful in all aspects, including purity.

And secondly, it should be Han Ziye, although Yi Lingxin's cultivation realm is higher than hers. But Han Ziye is a soul mutant after all, and his soul purity is stronger than the former.

Because she is a soul mutant, those points of light take on a black and white color.

After calming down a little, Ao Shuang also slowly walked towards the crystal ball, he didn't know if the purity of his soul would be as pure as Motian said. But I've come here with a lot of hard work, and I'm going to give it a try.

Ao Shuang didn't notice it, and when he walked towards the crystal ball, the pitch-black magic bead floating in the sea flashed slightly. Among them, a pair of eye pupils suddenly appeared, and the pupils of those eyes were full of cold, ruthless colors.

If the Demon Heaven was here, he would definitely recognize that when Ao Shuang in the western wolf's den was controlled by the Demon Ancestor that day, the look in his eyes was like this.

As if sensing something, Ao Shuang looked around in surprise, but found that nothing unusual had happened.

Immediately, his hands poked out of the black embroidered robe, slowly lifted, and pressed on the crystal ball.

"Hum!" Almost at the same time, the crystal ball suddenly began to tremble violently, and the sword-shaped mark on the palm of Ao Shuang's left hand also began to drill out with a steady stream of dark green soul power, finally enveloping the entire crystal ball.

"Boom!" suddenly there was a roar at the top of the tower, and the power of space began to change in some strange way, gradually forming a whirlpool-like cyclone at the top. Within that cyclone, it was as if something was rolling and sublimating!
