"Forget it, don't think about it, this Wood Emperor Palace is thousands of miles away from here, I'd better figure out what's going on here!"

Yunxiao shook his head, put the scroll into the Qiankun Xuanji bag, and then walked to the cave, looked at the cave, and found that the cave was pitch black, but there was a cold aura coming from the cave.

In the next hour, Yunxiao discovered more than ten caves large and small within the construction site closely guarded by the Aoki Sect. Some of the caves do not have any anomalous places, and there are many mortals mining here, but some of the caves are not only strictly guarded by a large number of Aoki Sect monks, but also have a powerful formation to protect them.

"What the hell is going on here, it's so weird!"

Yunxiao thought about it, took out a sound transmission jade talisman, poured it into the true qi, and soon the sound transmission jade talisman produced an image several feet in size, and the image showed the appearance of Li'er.

"Sister Li'er, did you find anything on the periphery? I found that there are strange caves everywhere, and some of them are quite dangerous!"

"I checked around and found that this is the place where we last killed the Wolf Demon King, and this place has been turned upside down by the monks of the Aoki Sect, I suspect that the Wolf Demon King's cultivation here is also related to the current strange situation here!"

After investigation, Li'er found that the snow peak occupied by the wolf demon king had disappeared, and the entire mountain peak disappeared, becoming what it is today. Just as Yunxiao and Li'er were about to leave, suddenly a dense black mist rose into the sky from the place where the Aoki Sect had been strictly guarded.

"Yin Qi!"

Yunxiao sensed the tyrannical and cold aura hidden in the black mist, and immediately knew the origin of this black mist.

"Sister Li'er, something is wrong, there is a yin and underworld aura here, let's leave immediately, or go down and have a look!"

Li'er thought for a moment and told Yunxiao to wait where she was. After the time of the half-pillar incense, Li'er's figure appeared. At this time, the monks of the Aoki Sect who were responsible for defending the construction site were all in chaos, and many low-level disciples even immediately hugged their heads and ran away after receiving the transmission. This puzzled Yunxiao and Li'er.

"What should I do, Sister Li'er?"

Li'er stared at a pair of beautiful eyes, looked at the gloomy aura rising like smoke in the distance, and said, "Let's go and have a look, things here are getting more and more difficult!"

In order to enter the most heavily defended place of the Aoki Sect. Yunxiao and Li'er knocked out the two low-level disciples of the Aoki Sect, and then changed their faces and blended into the monks of the Aoki Sect as if they were facing a great enemy.

"Uncle Qiqi Lu, after investigation, the disciples found that the black mist is very similar to the rumored Yin Qi!"

Not long after Yunxiao and Li'er mixed into the Aoki Sect, they followed a large group of Aoki Sect monks to the vicinity of a high platform. I heard that an elder of the Earth Immortal Realm was reporting to the high-ranking members of the sect.

"Yin Qi!"

A burly monk sitting in the middle of the high platform, hearing the advice of his nephew, his expression changed slightly, and he muttered for a while and said:

"Immediately send a powerful disciple to completely blow up this vein and seal this place tightly!"

"If you blow up the veins, will the other veins continue to be excavated?"

"The other veins are also temporarily sealed, and we will make a decision after our people enter the dungeon!"

As the burly old man made his decision, five Aoki Sect elders from the Earth Immortal Realm immediately took their disciples to the various ore veins. Yunxiao and Li'er blended into the team of Aoki sect monks, and walked towards the cave where the aura of the underworld came out, along the way. The two of them were relieved to see a large number of mortals being escorted away.

"All the disciples listen to the order, you follow your respective masters into the underground palace, remember to report any abnormalities immediately without delay!"

"Yes!"

The disciples of the Aoki Sect were divided into six teams, each team was led by two monks from the Tiangang Realm, and Elder Wei of the Earth Immortal Realm who led these monks of the Aoki Sect to this place was led by the entrance of the passage with two disciples of the Tiangang Realm.

Yunxiao and Li'er and the other eight Aoki Sect disciples of the Earthshatter Realm followed the two Tiangang Realm monks to the place where the Yin Qi came out, and when they came here, Yunxiao and Li'er saw clearly. The place where the Yin Qi came out was more than a hundred zhang away from the cave they were going to go down to, and that place was not a hole in the ground, it seemed that the Yin Qi was formed by spewing out of the ground.

"Sister Li'er, these Aoki Sect monks who don't know the power of the Yin Qi at all will go on like this. It's definitely a dead end, we should find a way to stop them!"

Li'er shook her head and whispered to Yunxiao: "I'm afraid it's impossible, you see that these monks don't follow the monks who would otherwise lead the team, it is very likely that they know the danger here, and the place they are going to may hide some secrets." Let's go and see!"

Yunxiao and Li'er followed the monks of the Aoki Sect silently, the cave was extremely deep and did not know where it led, and an everlasting lamp was hung every few zhang, illuminating the underground passage very brightly.

As we went deeper, the cave became wider and wider, and more and more Aoki monks appeared, from the three or five monks standing scattered at the beginning, to the later groups of monks lined up neatly along the direction of the extension of the cave.

"Senior Brother Zhou, will you lead the team down this time?"

The group of monks that Yunxiao and Li'er followed soon came to a place with a stone gate as a gateway and a heavily guarded place.

"It's Senior Brother Wang, there's no way, the sect master has an order, we have to figure out what happened down there as soon as possible!"

Senior Brother Wang's fellow disciples who were about to enter the stone gate carefully examined it, and then with a wave of his hand, two disciples immediately controlled the mechanism to open the stone gate.

After entering the stone gate, except for the two Tiangang Realm cultivators who were walking at the front of the line, the other disciples all looked at the place in front of them in amazement. I saw that the place behind the stone gate was a huge space, at least hundreds of miles in radius, and in the center of this space a palace made entirely of white bones towered.

Around this palace, eight waterfalls dozens of feet wide fell from the top of the space, emitting a deafening roar. It was not so easy to reach the White Bone Palace from where they were, because in this underground space, in addition to the disciples of the Aoki Sect, there were also disciples of other sects who appeared here, and the most important thing was that the next road was full of dangers, not only were there monsters of different strengths, but also gloomy ghosts appeared.

The top of this subterranean world is not very bright, and the eyes are full of dense jungles and rivers and lakes, but these jungles are not green but eerie black. From time to time, strange fish in rivers and lakes jump out of the water.

"Let's go down from here, and after we go down, don't stay away from the same door, and be vigilant at all times. No anomaly can be let go lightly. ”

"Yes, Master, Uncle!"

Yunxiao was a little surprised, he didn't expect that the dignified Aoki Sect Tiangang Realm cultivator would be able to accept disciples. There is a stone platform with a radius of more than ten zhang behind the stone gate, and under the stone platform is a bottomless abyss. Only a stone staircase more than three feet wide spirals downward.

"Master, can't we use the flying magic weapon to fly down from here?"

At this time, a disciple of the Aoki Sect who came to the stone steps and his face changed in fright, opened his mouth to ask, and another Tiangang Realm monk led by him said:

"There is no way to fly here, several masters have gone down to investigate that there is a formation with a forbidden air prohibition below, and the higher the cultivation of the monk, the greater the constraints of the formation, and there will be a decrease in cultivation!"

The words of this Tiangang Realm cultivator caused the disciples of the Aoki Sect to exchange their heads and discuss one after another. However, in the end, these disciples were still led by the two Tiangang Realm cultivators who led the team, and they trembled all the way down the steep stone steps.

"Brother Xiao'er. The aura down there is weird, what do you think?"

"The death qi here is very strong, but the Yin Qi has not yet been formed, and the Yin Yin Qi is very cold here, if I am not wrong, there should be a Demon Suppression Tower below!"

"Demon Suppression Tower! You mean there's a Demon Suppression Tower below that imprisons the Demon Boss!"

"It is very likely that the demonic qi below is the culprit that makes those high-level monks lose their cultivation, but the demon head of our Kyushu Continent has long been extinct, and there are no monks who have been exposed to demonic qi, after going down. Let's be more careful!"

Yunxiao and Li'er didn't know at this time that the powerful monsters in the Demon Suppression Tower that existed under the White Bone Palace had already escaped from the trap and disappeared, and some low-level monsters were wiped out by the ghost clan guarding near the White Bone Palace.

The demonic energy in the underground space is caused by the retention of a large number of demonic weapons that can only be controlled by some demons. Yunxiao and Li'er followed the Aoki sect monk for a whole day. It was considered safe to pass the winding stone steps.

"It's finally here, everyone, listen up, we will encounter a lot of unforeseen dangers below, don't panic in case of trouble, otherwise it will put everyone in a dangerous situation!"

Yunxiao and Li'er were in a group and the other Aoki Sect disciples were about twenty or thirty zhang apart, but it didn't take long for everyone to set off. A sudden turn of events disrupts the plans made by the Aoki sect.

The direction of the White Bone Palace, which had not made any movement, suddenly erupted into a rumbling sound, and then the entire White Bone Palace exploded. Due to the influence of the waterfall on the White Bone Palace, no one in the underground space noticed this huge change.

On the ground, those who were forcibly trapped by the formation of the white bones, black mist emerged one after another, and after a while, the hands and feet of the white bones stood up one by one, and the monks of the Aoki Sect who saw this scene were suddenly in chaos, and at the same time, near the border of the Northern Yan Empire, thousands of miles away from the construction site occupied by the Aoki Sect, the same snow peak collapsed, and a powerful ghost king led tens of thousands of ghost clan armies to rush out of the ground.

This army of the ghost clan marched along the inaccessible area towards the ghost city of Xudu in the southwest, and a similar scene happened in many countries, only the alliance of countries and the Jin kingdom did not have a similar thing.

"Senior Brother Zhou, do you think our Aoki Sect will be able to get the treasures in the Ghost Palace this time?"

"It's hard to say, I heard Master say that after the ghost palace appears this time, I'm afraid it will disappear completely!"

Senior Brother Zhou looked at the top of his head and replied a little absentmindedly.

"Why?"

Another Senior Brother Qian, who was standing side by side with Senior Brother Zhou, asked in surprise, Senior Brother Zhou didn't explain, just shook his head and ran in one direction, and Senior Brother Qian had no choice but to rush in the other direction when he saw this.

The other Aoki Sect monks didn't know that these disciples who came to the Underground World for the first time were actually here to seize the treasures within the Ghost Palace.

"Sister Li'er, come with me this way!"

Yunxiao pulled Li'er and hurried towards the northwest, and just as they rushed forward, a large number of ghost clans in the underground world came out of the ground.

"These damn vegetation are so tough!"

The black vegetation in the underground world is extremely difficult to cut down, so Yunxiao and Li'er can only forcibly burn these vegetation with fire bombing, so they gradually move towards the direction of the ghost palace.

More than ten miles away from the other direction of the ghost palace, a group of black-robed monks encountered a large number of fierce ghosts, and these fierce ghosts were gloomy one by one, holding rusty weapons and fearlessly rushing towards the humans not far away.

These monks hurriedly released shields of different colors, and then released magic weapons to attack the ghosts, but they didn't notice that a large number of ghosts crawled up under their feet, and it didn't take long for these monks to be killed by ghosts, and similar scenes were staged continuously, including those Aoki Sect disciples who came to the underground world with Yunxiao and Li'er An hour later, only the Senior Brother Zhou and Senior Brother Qian of the Tiangang Realm were still alive.

"Sister Li'er, be careful, there are more and more ghosts here!"

Yunxiao wielded the Excalibur Nameless to slash the ghosts one by one, but the ghosts that kept popping up under their feet made them scramble and difficult to deal with. Seeing that the situation was not good, Li'er recited the spell and suddenly transformed into a snake girl who was several feet tall and half human and half snake, and her tail swept wildly, shattering all the ghosts around her.

"Let's go!"

Li'er and Yunxiao couldn't deal with a large number of ghosts, so they could only use the wind blade and fire bomb technique to open the way, constantly dodging, and continuing to move in one direction.

A sword light flashed, and a ghost creature wearing bone armor was pierced through the skull by a sword from the sky, and the soul fire was immediately extinguished, turning into a pile of white bones again;

The spear in Li'er's hand stabbed out, instantly piercing the three ghost objects as a chest, and then swept out, the three ghost objects collided with more than a dozen ghost objects around them, and all of them were smashed into the skeleton at once, and scattered everywhere.

Yunxiao jumped forward, and sent out two wind blades in his hand in a row, shattering the two ghosts that stood in the way, and then rushed towards Li'er, only to see his sword flying, fire bombs, and wind blades, cooperating with each other, and finally rushed to Li'er's side. (To be continued.) )
