The speed of the cloud is very fast.

After passing a vertical passage, a cross-shaped passage stretched in front of her. She sniffed lightly and saw that the bloody breath was not coming from a passage, but from all sides of the intersection.

This kind of judgment made Yun Dan herself a little incredulous, and she couldn't help frowning, and swept towards the left passage where the bloody aura was the strongest.

Seeing the clouds sweeping towards the passage on the left, Lan Yan hurriedly followed.

Yun Dan glanced at him, and couldn't help but wonder in his heart.

I remember that before entering the Heavenly Dao Sect, Lan Yan's strength level was stronger than her. After entering the sect, after going through the Punishment Tower and the Heavenly Ladder List, her strength has improved by leaps and bounds. As for Lan Yan, he seems to be following the rules, he has been shrinking in the sect these days, almost never showing his head, and he has not made any out-of-the-ordinary moves, it stands to reason that his strength should not have improved so quickly.

When he entered the sect, he was still a first-order Great Spirit Master, and after a closer look at this moment, Yun Dan found that his strength seemed to have broken through to the fifth order of the Spirit Sect.

Yun Dan was a little annoyed.

Her breakthrough is blessed with a spirit core, and after refining the spirit core, her physique, which is not easy to cultivate, has been improved, so what about Lan Yan, how can he break through so quickly?

Isn't it said that in a place like Tianxi Continent, where the aura is barren, it's not easy to cultivate, and it's very difficult for others to cultivate, how can he cultivate so easily, the Chosen Son?

Yun Dan smelled something unusual from it.

After entering from the passage on the left, Yun Dan saw uneven blood stains scattered on the ground, some of which even saw the stone wall above her head, she settled down and told herself that Yun Jue's strength was good, even if she encountered a fierce beast, she could escape even if she couldn't defeat it, and there would be no accidents.

Thinking like this, her steps under her feet became faster, and after walking about five hundred meters forward, Yun Dan found the source of the bloody qi.

It was a body that was bitten by an unknown demonic beast, the body was cut off by the waist, the uneven wound was connected to the tendons, and the blood was hulala, just looking at such a picture made people's scalps numb, and they couldn't help but have synesthesia about the encounter with the corpse, and their waist also hurt.

There were tooth marks left on the waist of the corpse, which looked like it had been bitten off by something, two arms were missing, and only half of the head remained, making it difficult to distinguish the appearance of the corpse, and several pieces of broken cloth were distributed next to the corpse.

Squatting down, Yun Dan took out a short sword from the storage ring, picked up the rags on the ground, and carefully distinguished the color and texture of the broken cloth. z.br>

"Do you see anything?" After Lan Yan saw the physical characteristics of the corpse, he took out a blue brocade handkerchief from his sleeve, covered his nose, and took a few steps back.

"As you can see, this corpse is a man, and judging by the physical characteristics of the bones, it is probably between 100 and 500 years old." Yun Dan hooked her lips and glanced at him.

"Oh?"

Since this is the case, then this corpse cannot be Yun Jue's, she is relieved, and Lan Yan's heart is a little relieved.

Soon, however, he revealed another fact.

"As far as I know, Elder Lin and Elder Jiang's ages are within this range."

It's not that Lan Yan wants to think about things in a bad way, but before entering the Ancient Secret Realm, the disciples of his master Yuan Zhentian who are about to enter the Ancient Secret Realm, that is, he, Lan Dai, and Ye Undefeated gathered together and mentioned it to a few of them.

The primeval secret realm is a secret to going out, except for the three masters of the sect and a few elders, the rest of the people don't know that there is an ancient secret realm. Even if he knew that his master had already laid a hidden formation at the entrance of the Ancient Secret Realm, it would be impossible for others to find the entrance to the Space Secret Realm.

And there were only a few of them who entered the primeval secret realm, and when he saw the corpse of a human at first glance, he would inevitably not guess between these people.

Yun Dan shook his head: "Elder Lin and Elder Jiang are wearing special clothes from the sect, and these fragments of clothes on the ground look a bit standard, but they are still very different from the clothes of the elders of the sect."

Hearing this, Lan Yan also squatted down and looked at the rags on the ground.

The short arrow picked up the rag and stretched it out in front of Lan Yan's eyes, and Yun said lightly, "The head of our Heavenly Dao Sect

Old, the clothes they wear are slightly different, but they are all woven in the shape of a diamond."

"Diamond?" Lan Yan's gaze shifted from the rag to Yun Dan's face.

"Not bad." Throwing the rags on the ground, Yun Dan pressed the blade of the short arrow against the ground, and turned his wrist to wipe the blood stains on the tip of the sword with the ground.

"It is a way of weaving, the law of each row of this pattern is more complicated, from the beginning of weaving, it is necessary to draw a pattern in advance, wind the thread according to a certain law, and finally weave into a diamond-shaped pattern."

"You know this?" Lan Yan was a little surprised.

He was a businessman, and he did a lot of miscellaneous business, and he also did a cloth business, but it was all petty fighting. Like Yun Dan, he even knows the texture of the cloth so carefully, he really can't compare.

Yun Dan said, pointing to the blood-stained rag on the ground with his chin.

"Look at this cloth, although its color is not similar to the one worn by our Heavenly Dao Sect elders, this cloth is made of plain weave. So I deduced that this corpse came from another sect."

Speaking of this, Yun Dan raised his eyes and stared at Lan Yan's ice eyes, and asked tentatively, "When you came from this direction just now, didn't you really see anyone from other sects?"

"Nope." Lan Yan shook his head and muttered, "Master Venerable said that there are very few people in the sect who know the Ancient Secret Realm, and it is even more impossible for people from other sects to know the location of the Secret Realm, let alone enter the Secret Realm."

Yun Dan stood up, and the short sword in his hand "swished", and was put into the storage ring.

"In other words, someone in the sect has leaked the news of the Ancient Secret Realm."

Patting the non-existent dust on his hands, Yun Dan circled around the corpse, and couldn't see the appearance of this person, so he immediately summoned Xiao Ash, and the lid of the small ash bucket was opened, and half of the corpse on the ground was sucked into the bucket and stored in the small world.

"What are you?" Lan Yan didn't understand Yun Dan's approach.

"This body has to be gathered and brought with us, so that it will not be bitten by dogs when we get back." Yun Dan glanced at Lan Yan with her pair of aura-filled eyes, snapped her fingers, asked Xiao Ash to follow, and led Xiao Ash to the other three passages.

Soon, she found the stump and severed arm of the corpse in the other three passages, and finally put the corpse together.

After doing all this, Yun Dan stood in the passage and suddenly did not move, her eyebrows frowned slightly, and she looked at the long and dark passage behind her. An invisible sense of peeping stuck to her like a shadow, like a thorn in her back, making her very uncomfortable.

"Did you notice that too?" Lan Yan paused when he saw her movements, and couldn't help but lower his voice and said: "From the moment I entered that intersection, I noticed that someone seemed to be observing us in the dark, and that feeling disappeared in an instant, I thought it was my illusion, but I didn't expect you to notice it too, it seems that we have been targeted, but I don't know who the other party is."

Yun Dan didn't say anything, and secretly released her divine sense, strangely, her divine sense did not detect any suspicious aura around her.

He silently recited in his heart: "The first layer of different pupils, clear interpretation, open!"

A flash of bright color flashed in the two different pupils, one red and one blue, and the faint gaze swept towards the dark passage behind him without a trace, and clearly saw the silhouettes of the two figures in the darkness.

The two shadows were hidden in the darkness, as if they were born in the darkness, and they were skillfully integrated with the darkness, and even the breath was perfectly hidden.

"Boom!" Almost the moment she saw the two black shadows clearly, the spiritual power condensed in Yun Dan's hand condensed into a ball of flame, and she turned around and threw the flame in her hand towards the two black shadows.

"Flameburst!"

The fireball flew towards the deep passage with a fierce momentum, and with a clear drink from the clouds, the flames exploded, and after the dazzling firelight fell, the chaotic sparks dispersed the darkness, and the entire passage became bright.

Running quickly to the location of the two black shadows, Yun Dan twisted his head, and searched for the two black shadows with different pupils, but found that there was nothing around except solid stone walls and strange-shaped sculptures.

"How so?" She was surprised.

"What's wrong?" Lan Yan hurriedly swept over, standing beside Yun Dan, his eyes following her gaze

Saccade.

Yun Dan suddenly made a move, making him wonder and hesitate at the same time.

"It's nothing, it just feels like the person who just peeped at us is here." Yun Dan looked at him thoughtfully.

It seems that Lan Yan can't see those two black shadows.

She was telling the truth, but it was a partially obscured fact.

The different pupil is her hole card, and Lan Yan's purpose is not pure, she won't tell Lan Yan that she saw the two black shadows with the different pupil.

Yun Dan only felt frightened, and even his divine sense couldn't detect the existence of those two black shadows, so it was no wonder that Lan Yan thought that he had a delusion.

If it weren't for her superior ability to perceive different pupils, and her ability to see through the essence, even she wouldn't be able to spot those two dark shadows.

This situation can only show two problems, one is that the other party's strength is far above her and Lan Yan, and the other is that maybe the other party is not a spiritual cultivator at all.

Being able to perfectly hide his body in the dark, as if he was one with the darkness, Yun Dan thought that Yuan Zhentian, the strongest in the Heavenly Dao Sect, could not do it, except for Jun Qing.

Because of Junqing's strength and temperament, it is impossible to do this kind of hidden thing.

So, who will the other party be?

Lan Yan's deep ice eyes looked at Yun Dan steadily, his eyes full of doubts.

"Do you know something......

Before he could finish his words, the entire passage suddenly shook violently, and the sound of "click" came from all directions.

Squatting slightly, Yun Dan maintained his body balance, vigilantly checking the movements around him.

Suddenly, the ground was swept open by a thick pillar, which then quickly retracted below the ground, tearing the ground around it.

His feet were empty, and Yun Dan's body was weightless and suspended in the air.

She quickly adjusted the posture of her body, and the next moment, a short sword appeared in her hand, and forcefully pierced the short sword into the stone wall, her body slid down about ten meters, and the short sword rubbed sparks on the stone wall, and after a striking black crack was made, her body stopped sliding downward.

When she looked down, she saw that the pillar that had broken through the ground had rolled up the blue inkstone and dragged it deep into the ground.

"Senior Sister Yun, save me!" Lan Yan's body was tightly bound by the pillar, and in the weightless state, it was difficult for him to find a point of focus to break free from the restraints.

Yun Dan's eyes sank, but he had no intention of making a move.

Although Lan Yan was from the Lan family of Mozi Country, she always felt that Lan Yan had many secrets, and his deliberate proximity made her feel that his purpose was not simple.

If he could die here, it would be a good way to get out of trouble.

Lan Dai was quite sincere to her, she didn't kill him personally, even if she saw Lan Dai again, she didn't feel any guilt.

made up his mind, and in the face of Lan Yan's call for help, Yun Dan chose to pretend to be deaf and dumb.

But at this moment, Lan Yan's voice came from the dark underground: "Senior Sister Yun, I will use half of the property in the Holy Capital City in exchange for you."

Yun Dan's complexion did not change, looking up at the sky, unmoved.

Half of the property in the Holy Capital City was more inclined to the latter than to get rid of an unknown threat.

As if she knew what she was thinking in her heart, Lan Yan gave her a slap when she couldn't breathe.

"Senior Sister Yun, most of your wealth is on me, if something happens to me, you will lose a lot."

Yun Dan's mind flashed with inspiration, remembering the last time she climbed the ladder, she took out most of her property and placed a bet on Lan Yan, but later because of the delay between Yinyi and Junqing, and then entered the ancient secret realm, a series of things happened in full swing, and she didn't have the opportunity to ask for gambling money.

Unexpectedly, Lan Yan actually brought it up at such a time, I really don't know whether she should praise him for his wit, or scold him for being shameless.

Immediately spitting, Yun Dan let go of the hand holding the short sword, and flew backwards towards Lan Yan with his head down.

The light of the different pupils was bright, and in the dark crypt, Yun Dan accurately found the location of the blue inkstone.

She quickly stretched out her left hand, and her heart moved, and countless dark red silk strings stirred

Shooting down, like a red dark light, the speed of light pierced into the pillar that bound the blue inkstone, and with a sharp turn of the wrist, the silk thread instantly tightened.

With a "bang", the pillar that bound the blue inkstone was cut into tiny pieces.

"Hiss!"

There was a deafening hissing, and the entire space began to shake violently, and stones continued to fall overhead.

As soon as the confinement was loosened, the dark red filament released by Yun Dan wrapped around Lan Yan's thin waist, she pushed upward, Lan Yan's body was stunned, and she adjusted her posture with her strength, while Yun Dan's body fell quickly and caught up with Lan Yan.

The moment her body approached Lan Yan, a powerful arm grabbed her slender waist from behind, and a blue umbrella was immediately stretched above the heads of the two of them.
