"Among the eight types of monsters, there is indeed a great horror similar to the one called the sea monster! However, I have been guarding the Pacific Ocean for more than 40 years, but I have never seen such a monster, and I thought that the sea monster was just a legend."

"Now it seems that this monster really exists! Moreover, it doesn't seem to want us to open the land of the underworld."

Ace whispered, "Sea monsters?" He quickly gathered information from the Dragon Legacy.

It turns out that this creature does exist. It is said to live in the deep sea and its whereabouts are unknown. No one saw it in its entirety.

Most people face death after witnessing this terrifying creature. And those who survived by luck only saw its huge tentacles.

One of the most powerful things about this monster is that it can transform into a human and has the ability to confuse other people.

Ace looked at the center of the bottomless vortex, a little worried. He didn't know how many other terrifying creatures there were in the deep sea.

"Until I took out the Key to the Underworld, everything seemed normal. After I had the classics in my hands, the monster appeared. Does it mean that it senses the key to the underworld?" Ace analyzed himself.

He hurriedly put the key of the underworld back into the Void Bracelet, not daring to take it out at will.

For some time after that, everything was normal in the maelstrom, and nothing like that happened again.

When Ace was about to reach the most central area, in front of them, a layer of mist floated on the waves, and lightning flashed in them, not roaring.

"This is the origin of the lightning I just saw. This cloud is suspended here for some reason, blocking those who want to trespass." Demacia looked at the clouds in awe.

As Ace took a closer look at the clouds, Demacia reminded him, "We're here!"

Ace only felt the canoe under him spin at high speed, and then the canoe suddenly left the current and entered a space without seawater.

Ace looked around curiously and found that they had reached the bottom of the sea.

But the bottom of the sea under his feet was dry, and there was no current. The outer sea seems to be blocked by some huge mysterious force, making it impossible to enter this mysterious space.

Without the help of any external force, the boat landed very steadily on the sediment of the seabed.

Demacia smiled at Ace, "Welcome to the place we've been guarding, Maelstrom."

After eating, he pointed to an abrupt-looking stone door not far away and said, "That's the gate of the underworld!"

Ace walked over to the stone door standing in the middle.

He saw that the door was semicircular, divided into three circles from the inside out. Each circle is marked with a variety of strange characters and different colors.

However, in the middle of the stone door, there is a square groove with a depression.

Ace walked around the door and found that it was an ordinary semi-circular stone door, which didn't look special. From front to back, from left to right, there was no support, just standing there alone.

According to normal human understanding, even if the stone door is opened, it is still in a unique space under the sea, and there is no change from this end of the door to the opposite side.

Demacia pointed to the groove in the stone door and said, "This is the key to the underworld. You can put the Key of the Underworld in the recess to open the stone door."

Ace walked slowly to the stone door and gently touched the groove with his hand.

"I just need to put this canon in it? Is it that simple?" Ace asked uncertainly.

Demacia nodded, "According to the legend that has been passed down from generation to generation, this is what it does."

Ace looked at the classical in his hand, and then slowly embedded it in the slot.

The classical is perfectly matched with the groove and there are almost no gaps.

When the classical is embedded in it, there is only the sound of a semi-circular stone door cara, and the inner and outer three layers of stone slabs begin to move.

The words on the stone gate glow brightly and completely illuminate the entire sea.

The light even penetrates thousands of meters of seawater and shoots into the sky.

At the same time, a large number of marine life in the Arctic Sea began to slowly gather towards the maelstrom.

At this time, lightning in the center of the vortex

Also shot into the clouds, the whole sky suddenly became colorful. It really feels like a road to heaven.

In the clouds, many dragon figures can be seen flying, but only some shadows can be faintly seen, but the real dragon body cannot be seen.

Ace and his companions were at the bottom of the sea, so they didn't see a spectacular sight on the surface.

At this time, Ace and Demacia were so bright that they couldn't open their eyes.

Ace is good. After all, as a dark magician, he can use dark magic to cover his eyes and avoid bright lights.

But Demacia doesn't know magic at all. He could only close his eyes and cover them with his hands. Despite this, he still felt a sharp pain in his eyes.

At this time, Ace suddenly felt a strange smell and entered the maelstrom.

Worried, he immediately recited the dragon mantra and covered his eyes with a layer of qi. Then he opened his eyes and soon saw a strange aura approaching the land of the underworld.

By this time, the door had already opened, and it was a curtain of light that shook like water.

Ace didn't hesitate. The dark dagger in his hand flew straight into the air.

I just heard a surprised voice not far away, "Huh? I was discovered by a small thing!"

Ace snorted coldly, and then, without saying a word, directly summoned the "Dark Python".

As soon as the serpent appeared, it immediately occupied the gates of the land of the underworld, blocking the path of the mysterious man.

The blinding light quickly dissipated, and Ace immediately removed the barrier.

Ace stared at the subhuman who had suddenly burst into the maelstrom. His eyes were cold, and he couldn't see much emotion.

Demacia slowly opened his eyes. Then he saw a figure suddenly appear not far away. He shouted, "It's you!"

Ace frowned and asked, "Do you know him?"

Demacia said, "He is the mysterious subhuman I told you about, and he can ignore the lightning above the maelstrom."

Ace suddenly felt that it was no wonder that this person could break in so easily.

Mr. Yaren looked to be in his thirties. He was tall, with short white hair, and he was like a knife. The most unique are his eyes, flashing with lightning. It's incredible.

If Ace's perception wasn't very strong, maybe he would never have noticed it.

Ace and the sub-man who came suddenly hadn't spoken yet. Demacia pointed at the man and angrily rebuked him, "Who are you? Why do you break into the maelstrom again and again?"

The Asians didn't pay attention to Demacia, but kept looking at Ace with interest, and said in the subhuman language, "Dark mage? There is also a half-bloodline of elemental makes. This is rare. No wonder it can open the land of the underworld, interesting."

Ace frowned, "I opened the land of the underworld. I hope you know that."

The sub-human was amazed that Ace was fluent in the sub-human Lian language, and he said in the extremely standard New Delhi Mandarin, "You can open the land of the underworld, but I can enter when the door opens."

Ace hadn't answered yet, but Demacia on the other side shouted angrily, "I am the guardian of the Matrompool, and this empty door can only be opened to him, and no one else can enter!"

However, the Yarsians didn't care: "It's not up to you to decide!"

Demacia was so angry that he immediately pulled out the large bow at his waist and prepared to shoot with it.

Ace hurriedly stopped: "Don't be in a hurry, let's ask first."

Demacia saw Ace stop talking. After hesitating for a moment, he could only grunt and stop talking.

"I really want to know, what are you going to do in the Netherlands? Looking for the treasure inside?" Ace asked.

Mr. Yaren smiled mildly and asked, "What are you going to do there?" Is it for the treasure?"

Ace said indifferently, "I'm looking for answers."

"Answer? What answer do you want?" Mr. Yaren continued to ask questions.

Ace's eyes flashed with dissatisfaction, "It's none of your business."

"Well, I'm telling you, I didn't mean to do this for some bastard baby

thing. Something I need. To me, it's priceless, but to you, it's worthless." He always has a smile on his face when he speaks, which makes it difficult to tell if he is lying.

Just as Ace wanted to go further, the sub-man pointed to the underworld and said, "Let's hurry up and get in. I'm afraid in a little while, we won't be able to get in!"

Ace was about to retort when he saw the otherwise calm currents around him suddenly appear.

"You may not realize it right now, but you should go to the seaside and see the landscape created by the opening of the Underworld." Mr. Yaren said with a smile.

Ace didn't answer. His eyes kept staring at the deep sea not far away. He quickly sensed it with his intense senses.

Ace said in a deep voice, "There are a lot of krakens coming here, and some strange creatures that breathe stronger, but I've never seen them."

Mr. Yaren was not nervous at all. He said disapprerovingly, "What's wrong with the Kraken? Just some depraved elemental makes. The most dangerous are the eight sea beasts!"

"Eight sea beasts?" Ace soon realizes that this man is talking about eight powerful monsters in the Pacific Ocean.

Before that, Ace had already seen a sea monster.

Now, if the eight sea beasts rushed at the same time, there would definitely be no way for him to retreat.

"Let's get inside. Slow down a little too late!" After that, the tall man strode towards the land of the underworld.

But the black snake in front of the door suddenly stood up, spat out a letter, and looked at him with fierce eyes.

The sub-man shook his head helplessly and sighed, "Hey, you two stubborn guys, I don't care about them, even if the eight sea beasts come, I can go, but you don't have that ability!"

Ace ignored this. He glanced at where the Kraken was rushing, then pulled out a scroll of holy light magic from his arm.

Ace knew very well that the Kraken lived in the deep sea all year round and never surfaced in clear weather, so what they feared most was the Holy Light.

The scroll was broken, and a huge web of holy light appeared not far away, separating the Kraken from Ace and the others.

"It's useless. What you're doing now is a pointless fight, not to mention whether the Kraken will be afraid of such a broken net. Even if you're afraid, it's useless in front of so many krakens." The subhuman laughed at Ace's obstruction of the Light.

Soon, the first Krakens broke through the sea and entered the maelstrom.

They originally wanted to rush towards Ace, but they were stopped by the large net formed by the Holy Light.

But these Sirens didn't give up. They kept slashing through the web of light with their weapons. Soon, the net was broken.

The Krakens rushed madly towards the lands of the underworld. Then Ace waved his right hand, and countless dark vines appeared on the ground, trapping them all at once.

"Hey, do you really want to die? I don't care about you. I'll go first!" After saying that, the kind man jumped, escaped from the black python, and jumped into the land of the underworld!

Demacia glared angrily and roared, "You dare!" He immediately shot an arrow, but it was too late.

As soon as he opened his mouth, the sea gap above his head suddenly collapsed, and the raging water suddenly fell.

At the same time, a large number of benthic organisms poured into the maelstrom.

It was almost a respite, and the sea had already washed past Ace and Demacia.

"Let's go!" Ace shouted, and at the same time, the dark magic in his hand turned around and instantly dragged Demacia into the underworld.

The moment Ace entered the door, he saw many huge monsters rushing towards them.

Among them, there is a monster with huge tentacles, and that is the sea monster.

As soon as Ace and Demacia entered the door, the tide rushed down the stone door, and the door disappeared in an instant.

The sea monsters, which were only slightly slower, could only roar in the sea, venting their endless anger.

Ace quickly got up from the ground and looked around, only to find himself in a huge underground palace surrounded by brilliant lights.

He was surprised to find that the key to the underworld had returned to his bracelet at some point.

There was one at his feet

A straight path leads to a huge pool of water in front of you.

On both sides of the road, there are all kinds of treasures.

There are gold, philosopher's stones, all kinds of jewelry, and a large number of magic books.

Ace was deeply shocked by what he saw, as he had never seen so many treasures gathered in the same place, piled up in a mountain.

At this time, Demacia next to him angrily rebuked, "You bastard, who let you in!"

He rushed to Mr. Yaren in front of him and shouted.

The man didn't look back at all. He just looked at the huge pool in front of him and said, "As a guardian, you have even entered the land of the underworld, why can't I?"

Demacia was speechless by him. In fact, as the guardian of the Underworld, he could not enter.

But now the situation is really urgent. In order to save him, Ace had to take him into the underworld.

Ace walked up to Demacia and said, "Everything has happened, it's useless to continue dwelling, let's get things done first and go out."

With that, Ace moved on.

Demacia was forced to wear a mask of pain. As the guardian of this place, his ancestors have always followed the rules. Their family is only responsible for guarding the maelstrom, and cannot set foot in the land of the underworld.

But now, things have become like this, and he can only choose to accept it helplessly.

Ace came to the huge pool and looked inside, but saw that the color of the bottom kept changing.

At this time, standing very close, Ace could clearly feel that the temperature of the water was changing rapidly, and the hot air was steaming hot and cold air, which was really difficult to understand.

Looking around, he found that in this huge palace, apart from the various treasures piled up around it, there was only this huge pool.

"Oh, by the way, I forgot to introduce myself. My name is Ciro!" Then, the subhuman stood on the edge of the pool, ready to jump.

Ace was surprised. "What are you doing?"

Ciro, of course, said with a face, "Jump!"

Seeing that Ace was still at a loss, Ciro sighed and said, "I just said you don't have a brain, are you here to find the first layer of treasure?"

Ace came here after a great deal of hardship to find these so-called treasures. What he was looking for was Hades' traces.

According to Ciro, the underground palace seems to have more than one floor, and there is an entrance to a deeper part of the pool?

Ciro glanced at Ace blankly, "What? Don't you have the courage? If you stay on the first floor, you'll never get out! Because there's no exit here."

Ace looked around, then at the deep pool in front of him, and he couldn't see the end. For a moment, he fell into deep thought and hesitated.

"Hey, think about it slowly, I'll go first!" Ciro then jumped into the pool without giving Ace a chance to stop him.

Demacia on the side was very worried, but seeing that Ace still didn't move, he could only watch Ciro disappear into the deep pool.

Ace looked at Demacia dignifiedly, "Now we have no way out, we can only risk our lives to try."

Demacia's face was not at all afraid. His eyes replied firmly, "You saved me and brought me here. I obey all your arrangements."

"Well, you have to follow me closely when you get into the water, and you can't be more than two meters away from me!" Ace whispered.

After they agreed, Ace took out the white dragon ball and went into the water first.

Demacia did not hesitate to follow.

Once inside this deep pool, Ace felt nothing more than the scorching heat around him, completely enveloping him and Demacia.

Luckily, they are protected by Dragon Ball's waterproof cover, so the hot water around them can't reach them. But even so, the burning sensation made them uncomfortable.

Ace is fine. After all, the sun and moon marks on his forehead give him cool air from time to time.

On the other side, Demacia needs to rely entirely on itself to resist this fierce contact. Just a few seconds into the water, his forehead

The head began to sweat incessantly.

While they were still adjusting to the intense heatwave, the surrounding temperature dropped to the lowest point in an instant.

The original heat suddenly disappeared, replaced by a biting cold.

Ace had noticed the unusual features of the pool when he was above it, and he had a deep understanding of it while he was in it.

The extreme change in temperature made Ace feel very uncomfortable, not to mention Demacia, who had no magic.

"Oh, what's going on with this pool? It's hot and cold!" At this point, Demacia began to tremble incessantly.

In addition, he was sweating all over just now, and now, under the influence of the cold, he felt frozen all over.

Ace frowned, then took out an alchemy pill from his arm and handed it to Demacia, "Eat it. It can help you improve your body's resilience in a short period of time and resist rapid changes in temperature."

Demacia trusted Ace and immediately swallowed the pill.

The pill melted at the entrance, and Demacia felt an indescribable sensation running through his body, making him feel refreshed and relaxed all over.

Ace hurriedly looked in all directions, and saw that the pool seemed to be large, and there were more holes underwater.

At this time, he couldn't find Ciro at all, so he had to rely on his perception ability to slowly grope for the entrance to the second floor of the underground palace.

After Ace finished speaking, red dragon patterns appeared in his eyes, and the scene in the pool quickly appeared in front of his eyes.

He found that there were stone walls far away from him, and there was no exit. He only has his own feet and an invisible waterway.

Now all he can do is move on.

"For ordinary people, they can't even get close to the whirlpool. After all, they were taken care of by Demacia. Even if they came in a whirlpool, how many would be able to pass through the dense and terrifying lightning?"

"Even if you do enter the maelstrom, you still need the key of the underworld to open the land of the underworld and enter the first floor of the underground palace."

"To say the least, even if we enter the first floor of the Underground Palace, how many of us will be able to withstand the drastic change in water temperature and find the entrance to the next floor of the Underground Palace?"

Ace sighed inwardly. No wonder no one has been able to find the ruins of this underground palace for thousands of years. The levels set up by Hades stopped almost everyone.

Ace soon spotted a gap in the stone wall to his right.

He took control of the water shield and slowly walked towards the stone wall. It soon became clear that it was a very inconspicuous hole. If he didn't have amazing insight, he probably wouldn't have noticed the hidden entrance.

Ace looked at the unfathomable cavern and said to Demacia, "Be careful. There could be more dangers in this cave."

Demacia nodded, and immediately lowered the large bow at his waist to alert himself.

At this point, he just wanted to get out of this damn weird pool as soon as possible, because the extreme temperatures really made him unbearable. Even after taking the alchemy pill that Ace gave him, he still couldn't bear it.

Ace stared carefully at the inside of the cave, probing everything in the cave with a keen eyesight.

However, he could not immediately see the deepest part of the cave.

Demacia's eyes darkened. He couldn't see his surroundings at all. He could only rely on the extremely weak light of the water shield itself to keep track of Ace closely.

At this time, Ace also had to be grateful. Luckily, Gaia gave him the Dragon Balls, otherwise he would have had to deal with more difficult situations at this point.

Ace squinted at Demacia and noticed that his eyes were full of anxiety.

Indeed, how can one not feel uneasy in this oppressive and dark environment, combined with the ever-changing temperature of the water?

"Well, luckily, we've done enough preparation before this trip, so the magic scrolls are quite plentiful." Ace took out three or four low-level holy light scrolls from the crook of his arm.

All the inscriptions on these scrolls are the main Holy Light Magic "Orbs of Light", which are used for illumination.

With the appearance of the first ball of light, the scene inside the cave gradually became clear. On the surrounding stone walls, it seems to be carved

A wide variety of characters. But at this time, the two did not take a closer look calmly, but just wanted to pass through the cave as soon as possible.

After the ball of light turned seven and eight times, after using the three magic scrolls of the "Light Ball Technique", Ace and the others finally saw a ray of light in the distance.

They both took a breath of relief at the same time, and then Ace quickened his pace and quickly walked towards the cave exit.
