With a shocking roar, Lu Yang, Qing Miao, Xiao Hei, and Yan Xun were startled at the same time, and the eyes of the four looked at the sky above the valley at the same time.

I saw that above the valley within the underground palace area, black clouds quickly converged, and a rich demonic qi, like wolf smoke, rose from within the underground palace area.

"The first Demon Emperor bone is here......"

Yan Xun snapped, and then his old figure swept up violently and swept towards the valley.

The three people behind Yan Xun, Lu Yang, Qing Miao, and Xiao Hei, also had a realization the moment they saw the demonic qi, and the three figures followed Yan Xun's figure almost at the same time.

At the same time, the two elders of the Taichu Hall and the three hundred flame soul guards led by the two Gongye people also noticed that the vision occurred in the sky above the valley, and more than 300 people rushed towards the valley at the moment when the vision occurred.

"Woohoo"

Countless wind-breaking sounds resounded in the valley, and more than three hundred figures, in only half a pillar of incense, had already seen the giant peak that had collapsed nearly half, and the underground palace where the first demon emperor was buried was in the mountain that had collapsed nearly halfway.

At this moment, I saw that the pitch-black demonic qi like billowing wolf smoke was constantly gushing out from within the mountain, and the sky above the half of the giant peak was already shrouded in the billowing demonic qi.

"Everybody come with me......"

Seeing this scene, Lu Yang did not slack off, because in the underground palace where the first Demon Emperor was buried, Lu Yang's spiritual power had already entered once before, and the collapse of the giant peak was also related to the previous bombardment of Lu Yang's spiritual power.

Therefore, Lu Yang, who had entered the underground palace once, stepped forward and led a group of more than 300 people to storm in the direction of the underground palace.

A moment later, under the leadership of Lu Yang, a group of more than 300 people had already arrived in front of the dark giant gate of the underground palace.

On both sides of Lu Yang's side, Yan Xun, Qing Miao, and Xiao Hei always stayed on their sides, and the three of them were extremely vigilant to protect Lu Yang.

Behind Lu Yang, the two elders of the Taichu Palace, as well as the three hundred Flame Soul Guards led by the two Gongye of the Flame Soul Clan, followed closely behind.

"Hmph...... Really fast, to clear the ruins so quickly......"

Lu Yang looked at the pitch-black giant gate that opened slightly in front of him, and couldn't help but snort coldly, the collapse of the giant peak had buried all the pitch-black giant gates, and now the appearance of the pitch-black giant gate was obviously the black-clothed building people cleaning up the mountain rocks, and only then did the portal of the underground palace be revealed again.

"Boom"

With an earth-shattering roar, Yan Xun slapped a palm print on the pitch-black giant gate.

"Boom"

The portal of the underground palace, under the palm of Yan Xun's air, opened to both sides, and a touch of light shone into the underground palace with the opening of the giant gate of the underground palace.

At this moment, everyone present saw that the underground palace was completely shrouded in the billowing black demonic energy, and the naked eye could no longer see the situation in the underground palace.

Seeing this scene, Lu Yang and the others did not act rashly, because the demonic qi that did not belong to Moduo before, everyone had already comprehended it, obviously, the weirdness of the demonic qi in the underground palace at this moment was countless times weirder than the demonic qi released by Moduo before.

"Listen to the people of the black-clothed building, you have been blocked in the underground palace, even if you have wings, it will be difficult to leave this place, hand over the Demon Emperor bones if you know each other, maybe you can still save a life......"

Lu Yang's voice sounded coldly, at this moment, Lu Yang also did not dare to act rashly, the degree of demonic energy in the dungeon made Lu Yang not recklessly release his spiritual power to enter the dungeon to investigate.

"Quickly hand over the Demon Emperor Bone ......"

"If you dare to disobey, you will die without a place to bury your heart......"

As Lu Yang's voice fell, the three hundred flame soul guards behind him burst out one after another, and their momentum suddenly exploded.

However, after everyone shouted loudly, there was no sound of response in the dungeon, and only the billowing black demonic qi in the dungeon roared.

"Hahaha, Xiao Xiao of the Black Building, do you think that with these ancient demonic qi you can stop our steps......?

Yan Xun's voice rang out, and in the moment of his words, a crimson streamer burst out from the center of his brow.

Suddenly, the Taichu Xuanhuo Tower appeared in the crimson streamer, the Xuanhuo Tower rose against the storm, and after it skyrocketed to the size of several zhang, it immediately stopped, and then a red light curtain fell from the top of the Xuanhuo Tower, enveloping Lu Yang and his party of more than 300 people.

"Go, if you meet someone in the black building, you will be killed......

Under Lu Yang's orders, a group of more than 300 people, under the protection of the light curtain of the Xuanhuo Tower, stepped into the underground palace.

"Hula"

With Lu Yang and his party of more than 300 people walking into the dungeon, the rolling demonic qi in the dungeon scattered in all directions, and the space where the Xuanhuo Tower was located suddenly dispersed.

Lu Yang and his party of more than 300 people quickly went deep into the underground palace under the protection of the Xuanhuo Tower, Lu Yang was quite familiar with the environment in the underground palace, under the leadership of Lu Yang, the group did not delay the time at all, and after a while, they had already come to the portal where the previous "Xuanmo Heavenly Soul Drum" was located.

A group of more than 300 people followed Lu Yang and stopped, and Lu Yang's eyes were looking towards the opposite wall.

Because, the spirit of spiritual power condensed by Lu Yang had entered the underground palace once before, and in the underground palace, Lu Yang understood the location of the eight portals very clearly.

And when Lu Yang's gaze turned to the opposite wall, Lu Yang's face couldn't help but be taken aback.

As the demonic qi dispersed, the place where Lu Yang's gaze touched was no longer demonic qi, and Lu Yang was surprised to see that the portal seal on the opposite wall had been broken, and the bronze giant gate had been opened.

What Lu Yang was surprised by was not the opening of the portal, but what Lu Yang was surprised by was that within the portal, there was a faint spatial energy coming out of it.

While Lu Yang was shocked, Qing Miao and Yan Xun were both aware of it, and the moment the three of them discovered this faint spatial energy, the expressions of the three of them all became solemn at the same time.

"Door ......"

At the moment of discovering that faint spatial energy, Yan Xun let out a loud shout, and then more than three hundred figures poured into the huge bronze portal almost at the same time.

After entering the huge bronze portal, the first thing that caught everyone's eyes was a huge space, this space was thousands of zhang, and the strange thing was that there was not the slightest demonic energy in this portal, and a huge altar not far away clearly appeared in front of Lu Yang's group of more than 300 people.

I saw that on the huge altar, a crystal coffin emitting a bright white light was quietly parked on the altar, and at this moment, the lid of the crystal coffin had been opened and docked next to the coffin.

On the other side of the altar, there is a stone henge of nearly 100 zhang, and at this moment, the gray-black light is dissipating little by little above the stone henge of nearly 100 zhang.

Lu Yang looked at the stone formation not far away in surprise, and Lu Yang clearly felt that the faint spatial energy that had emanated from this stone formation was emanating from this stone formation......
