The underground palace is the weaker palace in the Divine Heavenly Palace, and the most powerful is the Heavenly Palace, among which the strength of the Thunder Palace, the Fire Palace, and the Water Palace is also quite strong, and they are all stronger than the underground palace.

Originally, each palace had a supreme-level dragon man in charge, but now I don't know what happened, the supreme of the underground palace and some heavenly monarchs have left the underground palace, and this news is in the hands of the major forces, but they can't fall out with the gods now, after all, this god clan is an existence that is more powerful than the dragon temple, so they didn't do anything, but Zhuo Yu is not afraid, he just needs to be careful, and he will never let others know.

Zhuo Yu dived into the deep ground and used his spiritual power to investigate, because the underground palace was built under the deep ground, and no one knew why this palace existed, although the strength of this underground palace was very weak, but it was the most mysterious.

The three Xuan Demon Souls were rapidly advancing in the depths, and soon saw some faint light in front of them, Zhuo Yu saw some stone walls through the Xuan Demon Soul, and the Xuan Demon Soul passed through the stone walls and came to some passages, these passages are all made of stone bricks, and the four walls are inlaid with some fluorescent stones to illuminate the passages, this is the underground palace!

Building an underground palace doesn't look so luxurious, but what secrets are hidden inside?

Zhuo Yu used his shadow transformation magic power to pass through the formation that protected this dungeon, and just now the tree spirit told him that this dungeon was protected by three powerful formations, and the arrangement methods of these formations were very ancient, they were arranged in ancient times!

"I know, there is a very good chance that there is a dragon in this underground palace! Back then, the Divine Dragon sealed these dragons to imprison their strength and souls, and let them fall into a long sleep, and now they must have woken up, but they still haven't broken the prohibition set by the Divine Dragon!" The tree spirit suddenly said excitedly, the Eight Great Dragon Emperors were sealed back then, but where were they hidden? This has always been a mystery.

"Sister Tree Spirit, this underground palace was built by the Protoss. Zhuo Yu said.

"What's this, the Divine Dragon Hall and the Protoss were originally united, and the strength of the Divine Dragon Hall is limited, it is difficult to hide the Eight Great Dragon Emperors, if they are hidden by the Protoss, who will know? Wouldn't this be a good way?" ”

Thinking of this, Zhuo Yu was immediately excited, because this Dragon Emperor was now sealed, without any combat power, and there was no one to protect him.

"What if I find it?" Zhuo Yu used two Xuan Demon Souls, one followed closely behind to prevent some hidden and powerful people from appearing, and the one in front was to explore the path.

"Don't you have the Cloak of the Nine Shadows?" the tree spirit yin laughed, which made Zhuo Yu's heart flutter, thinking that he was going to get rid of a divine beast, what an exciting thing it was, but now he was not sure, the Dragon Emperor was here.

"I think this Dragon Emperor should be the Heavenly Cold Dragon Emperor who cultivates the power of Yin and Cold, because there are Nine Hidden Lakes here, so a large area of land is covered by Yin and Cold all year round, if the Heavenly Cold Dragon Emperor wants to break the seal, he has to absorb the power of Yin and Cold all year round! It is very possible to hide the sealed Heavenly Cold Dragon Emperor here. ”

The tree spirit was now even more certain, because as soon as Zhuo Yu entered this underground palace, he felt that the power of the cold here was much stronger than outside, and it was obviously absorbed through the formation.

Suddenly, Zhuo Yu stopped, because the Xuan Demon Soul who was walking in front found that there were several stone doors on the two walls, and he let the Xuan Demon Soul enter one of the stone gates, which was a small and simple strength, only to see a dragon man sitting cross-legged on the ground, absorbing the power of the cold here, and was cultivating, and pieces of black dragon scales appeared on his body, and at a glance, he knew that he was impacting the dragon transformation stage.

Zhuo Yu thought to himself: "There are a total of eight stone doors, could it be said that there are people cultivating behind each door? Could this be the place for cultivation?"

Opening a stone door, the man was immediately awakened, he looked at Zhuo Yu coming to disturb him, his face was suddenly full of anger, and he snorted: "Don't you know that you can't disturb others here? ”

Zhuo Yu smiled slightly: "I'm not here to disturb you, I'm here to ...... Kill you!" As soon as the words fell, Zhuo Yu had already rushed in, and in the blink of an eye, he came to the person's body and slapped it down with a strong palm, knocking the person unconscious.

The three mysterious demon souls entered this person's body, quickly searched the memory of this dragon man, and learned about this dungeon, what surprised him was that this was actually a dragon man, and the dragon man would be in the dungeon established by the god clan......

It didn't take long for Zhuo Yu's brows to lock deeply, and he muttered: "It turns out that there is really a Dragon Emperor hidden at the bottom of this, but I didn't expect this group of guys to do this kind of thing in order to let the Heavenly Cold Dragon Emperor quickly get the strength to break through the seal!"

Feeling the anger in Zhuo Yu's heart, the tree spirit hurriedly asked, "What's the matter?"

"This group of guys has always been on Tianfan Island, catching some humans with good qualifications, tricking them into cultivating here, and when they all cultivate to a certain extent, they will take these people to the location of the Heavenly Cold Dragon Emperor, and let the Heavenly Cold Dragon Emperor suck these people dry, and their souls and flesh and blood will be sucked out! I don't know if other Dragon Emperors are doing the same!" Zhuo Yu clenched his fists tightly and struck the dragon man's abdomen with one palm, erasing the consciousness inside the dragon baby, and then put the corpse into the Nine Shadows Cloak and practiced it into a ghost.

"And what does this man do?" the dryad asked.

"These dragonmen are all selected, and they are specifically responsible for guiding human cultivation, and sometimes they will go out to hunt human beings! They also have to cultivate, so every once in a while, they will come in here!" Zhuo Yu left this stone room and walked to another room, killing the dragonmen inside.

It didn't take long for all the dragonmen behind these eight stone doors to be killed by Zhuo Yu, turning them into eight ghosts, and their own strength was only Xuan Immortal Triple Heaven, so they were not Zhuo Yu's opponents at all.

"Since there is a Heavenly Cold Dragon Emperor here, why would the Supreme Heavenly Monarch leave?" the tree spirit asked again.

"Not all the Heavenly Monarchs have left, there are still four Heavenly Monarchs guarding here, they are all very confident in the formation they have laid down, and the Heavenly Cold Dragon Emperor has regained consciousness! Therefore, the Supreme and a group of Heavenly Monarchs all personally dispatched to directly catch some people who cultivated the power of Yin and Cold and came back!" Zhuo Yu said, shaking the Nine Shadows cloak on his body, only to see eight people coming out of it, these were the eight dragon people he had killed just now, and now they were all equivalent to Zhuo Yu's clones.

Zhuo Yu knew that he would have to stay here for a while, so in order not to arouse suspicion, he had to do this.

"Conscious Tianhan Dragon Emperor, I don't know how his spiritual power attack is, if it is strong, it will be difficult to deal with, if Ding Ling this guy wakes up, it will be fine!"

The tree spirit was a little worried, because she knew very well that Zhuo Yu would definitely deal with the Dragon Emperor, and she was worried that Zhuo Yu was not strong enough to collide with the Dragon Emperor.

"Don't worry, I have a way to deal with it, the Dragon Emperor is one layer below, after he was sealed, he turned into a body, and that is a big guy. "If he wasn't so confident when he didn't get the Nine Shades Cloak, this kind of God-Emperor level existence would be very difficult to kill.

But he has an artifact!Nine Shades Cloak, that Purgatory Fire can clear the consciousness in the soul, but it may take a while, not to mention that this Heavenly Cold Dragon Soul contains the power of Yin and Cold, if the power in the soul is incinerated, it will definitely allow his Nine Shadows Cloak to evolve.

"He only has consciousness, no power to attack, and the Divine Dragon was quite completely sealed back then, so these guys in the Divine Dragon Hall have always been secretly protected, and they have used a lot of resources to arrange some powerful formations, but these formations are not worth mentioning at all to me. ”

The corners of Zhuo Yu's mouth turned up, revealing a smile, he was very familiar with this underground palace at this time, and soon entered a hall, the hall was empty, only some cold stone benches, it was dim, obviously he rarely used this place.

"What's your plan?" asked the dryad.

"I'm going to use Yuan Ying to quietly set up a formation and blow up the entire underground palace, provided that it's before the Supreme and the Heavenly Monarch come back!" Zhuo Yu walked towards a wall, groping with his hand on it.

"Hehe, I know this formation, I'll teach you how to arrange it, but you have to figure out how much this dungeon has. The tree spirit laughed, back then, the Divine Dragon Hall participated in destroying her and killing many ancient wood clans, so she hated the Divine Dragon Hall very much.

Zhuo Yu Demon found a very smooth stone brick, and then pressed it gently, only to see that the stone wall suddenly lit up, turning into a stone wall with white light, he stepped into it, and came to a long passage.

"Where is this?" asked the dryad, barely feeling it, as if she had crossed space.

"I passed through the teleportation array and came to the bottom of the deep ground, this should be a place as deep as ten thousand feet, there is a very large hall in front, and there is the Heavenly Cold Dragon Emperor in it! I didn't expect the Protoss to help the Shenlong Temple so much, build such a perfect place, and send their Protoss Supreme to garrison it. Zhuo Yu said, walking briskly before, there were still two Xuan Demon Souls, one in front and one in front of the other.

"You clean up the Heavenly Cold Dragon Emperor, if the Divine Dragon Hall and the Divine Heavenly Palace know about it immediately, you won't have time to set up a formation here!" the tree spirit said: "Otherwise, don't blow up this place, they lost a Dragon Emperor, it's already miserable." ”

Zhuo Yu thought for a while, shook his head, and said, "No, there are more than three hundred people here, both the God Clan and the Dragon Clan, and over the years, they have captured many humans to come here." ”

Since this kind of thing has been encountered by him, he will never be soft, and he must punish these people well, even if it is a waste of the Yuan Ying he has collected.

The passage had come to an end, this was a stone door, Zhuo Yu slowly pushed it open, only to feel a cold air coming, making him shiver all over, and then a dazzling white light squeezed out from the crack in the door!

The stone door opened, he was stunned, it turned out to be a cold and snowy place, and the wind was gusting, and he also saw the dragon lying in this ice and snow!
