Looked at Diego and Andal.

After a moment of contemplation, he commanded.

"Put them in custody and keep them heavily guarded."

Now that the army of Dragon King City has been dispersed, there is no cause for concern that some of the remaining remnants of the army will be defeated, its ruler Diego has been captured, and the national teachers and other commanders have all been killed in the previous wave of battles.

It can be said that the fall of Dragon King City has become an established fact.

Ordered the Sangonomiya army to be stationed in the city to maintain order, and then let the knight legion guard the secret treasury of Dragon King City under the leadership of a blue hero.

According to Anina's description, in addition to the plane keys, there are also a large number of resources and treasures accumulated by more than ten generations of Water Dragon Kings in the treasure house of Dragon King City, which is enough to make the strength of the crown of the ocean skyrocket again.

Although he was quite curious about the amount of this wealth, Ji Chen knew that what was important now was to get the other plane key in his hand first, leave before the door of the secret realm closed, and anchor the secret realm of the Great Fluorescent Sea.

"Take me to the kingdom of men above the sea."

Sonia nodded, a strange color flashing across her eyes again.

Ji Chen and the others followed Sonia all the way to the Fluorescent Forest, and began to swim upstream between the pitch-black high-rise buildings.

The tall seagrass blocks the view to the left and right, but the fluorescence it emits also provides illumination, and after swimming hundreds of meters in the direction of the seagrass, away from the light of the fluorescent forest, the surroundings are barely dark.

When I looked back, I realized that the fluorescent forest and the fluorescence near and far were so shining.

"My lord, the reason why the Great Fluorescent Sea is called the Great Fluorescent Sea is because there are a large number of fluorescent plants growing hundreds of meters and thousands of meters at its bottom, which not only provides a certain amount of lighting, but also serves as the most basic food for the bottom sea tribe."

"The existence of fluorescent plants provides a space for the creatures of the large fluorescent sea to survive."

"But the thousands of meters between the kilometer and the surface of the sea is a pitch black with no light, like a dead field, in which there are a large number of primitive sea tribes who lack intelligence and can only kill and eat."

"There are also many relics and buildings left behind by the continuous migration of humans, and there may be some resources and treasures preserved in them."

Ji Chen nodded clearly, it turns out that there is such a place in this Great Fluorescent Sea Secret Realm, and it seems that there are still many secrets buried in it.

"Does that mean we need to get rid of those primordial sea tribes all the way to the surface?"

"Not really." Sonia smiled and shook her head, "Over the past thousands of years, the Sango Palace has also found a safe passage to the sea above the Fluorescent Forest from attack. ”

After crossing the top of the fluorescent forest, the group continued to ascend.

The surroundings are getting darker and darker, and the darkness is a little unsettling.

But soon, a little light appeared in the endless darkness ahead, and as the distance decreased, the light changed from a point to a circle, and slowly dispelled the shadow in his heart.

It wasn't until the distance was shortened to ten meters that they discovered that it was a cave with a diameter of seventy or eighty meters and an interior that was vertically upward.

On the walls of the cave, some fluorescent plants have been artificially planted.

"Lord Ji Chen, as long as you follow this cave all the way up, you can reach the sea."

Ji Chen bowed slightly, no longer delaying the time, led the army into the cave, and continued to float.

The interior of this cave is quite straight and spacious, and there are many fluorescent plants along the way, but it does not look cramped.

The crowd floated up without stopping.

A few hours later.

The cave finally swam to the end, and after passing through the hole, I looked up and saw a ray of light overhead.

But this is not the light of the fluorescent plants, but the sunlight they are very familiar with, the sunlight shining through the shallow water into the sea, the water turning from dark blue to light blue, and the atmosphere of the surrounding environment is much more relaxed.

On the expansive blue sea, a fishing boat stopped, and the fisherman on board was about to cast his nets.

But suddenly, more than a dozen huge dragons sprang out of the sea not far away, and their huge bodies jumped high out of the sea and then smashed down, splashing into the sky.

Just when the fishermen thought they had seen a whole school of whales and were excited, hundreds of bales of water bulged around the dragons, and sea creatures of different shapes jumped out of them, instantly filling the entire sea.

A man also emerged from the water and stepped on top of the dragon's head.

Ji Chen looked around, felt the sunlight shining from overhead, and let out a long sigh of relief.

Compared with the overall dim and cold seabed, it is still more comfortable on the sea surface.

Sonia on the side also looked around with some emotion, it had been hundreds of years since she last came to the sea.

Ignoring the fishing boats not far away, the group continued to move towards their destination without stopping.

The exit of the cave was not far from the human kingdom on the sea, and after half an hour's march, Ji Chen could already see a group of islands in the distance.

On one of the largest islands, stands a human city.

Behind the low city wall less than ten meters high, there is a low-rise house that is not even comparable to the black gold square of Maple Grove City, that is, the royal palace and castle in the center of the city are slightly more decent.

It was more of a small town than a kingdom, and the population of it was no more than 10,000.

There were several dilapidated twin-sail warships moored in the harbor outside the city, and the only small ballistas in the battery were a few small ballistas that could only be used to fight mosquitoes.

When he got a little closer and saw the panicked soldiers on the port, Ji Chen's heart flashed with a hint of disappointment.

The highest rank of these soldiers is only 2 stars of the second order, and the level is not even 20 levels, which is really too weak.

The so-called foreign invincible foreign trouble.

It seems that in the past thousands of years, with the closure of the gate of the secret realm, these secret realm humans have lost their land and even their combat effectiveness.

The arrival of the Crown of the Sea army naturally attracted the attention of this human kingdom.

More than a hundred human soldiers in cotton armor received the news of the enemy invasion and rushed out of the city gate to the port.

But as soon as they saw that the Champions of the Sea, who were more than ten times more numerous than them, their legs were almost weak, and they had no intention of fighting, so they ran back to the city and closed the city gates.

In the cramped royal palace, the general came to the king's palace in a panic.

"Your Majesty, I have something to report!

”

The obese king, who was playing blindfolded hide-and-seek with his concubines, heard this, and impatiently tore off the blindfold, "Hurry up and say something about it, don't disturb my interest!" ”

"There is an enemy invasion, and there are at least three thousand or more in number!"

The fat king's face turned pale.

Three thousand? His kingdom's army was only four or five hundred men!

Where did so many enemies come from!?

"Where have they been?"

"It's already at the port! But they all look like some sea creatures, maybe they can only be in the water, not ashore? ”

The fat king breathed a sigh of relief when he heard this, returned to the throne and sat down, took the handkerchief handed by the concubine, and wiped the cold sweat on his forehead, "That's good, that's good..."

But at this moment, the panicked voice of the soldiers came from outside.

"Your Majesty, the enemy has come ashore! Heading for the gates! ”

The fat king slid from his throne with a snap, his eyes blank, and he muttered, "It's over, my kingdom is dying..."

Ji Chen looked at the frightened soldiers on the low city wall and asked sideways.

"These secret realm humans are the descendants of those humans in the beginning, and it seems that they have completely abandoned themselves."

Sonia's face was complicated, "The rising sea is pressing their living space, and there is no land to grow crops, and the population is decreasing... But I didn't expect them to fall so far that the whole country couldn't even make up a thousand soldiers. ”

"My lord, I beg you for one thing."

Sonia said with a sincere expression.

"If they choose to hand over the plane, can they be spared?"

After Ji Chen thought for a while, he nodded.

"Yes, I grant your request."

"I don't like killing, I just want to get the plane key."

Hearing this, Sonia saluted gratefully.

"Thank you for your leniency, I am willing to persuade them on your behalf."

On the city wall, the fat king saw thousands of fierce enemies waiting outside the city, his face was extremely pale, and his legs were almost paralyzed, but fortunately, the general quickly caught them.

At this time, they saw a beautiful woman walking out of the enemy line.

Said coldly.

"Hand over your king's token, and spare you from dying."

The fat king was stunned and asked for his king's token?

Although he didn't know why, a surge of courage suddenly rose in his heart, and he gritted his teeth and asked.

"Dare to ask Your Excellency, who are you?"

"I am the Lord of the Crown of the Sea, a subordinate of Lord Ji Chen, and the Lord of Coral, Sonia."

Coral? Sonia?

The fat king sounded a little familiar, as if he had heard it before, and looked at the cold and noble face, with a few white scales on his forehead, and suddenly remembered.

In a fragmented book handed down by the royal family, it seems to mention that a long, long time ago, the soil of the kingdom was ten thousand times larger than it is now, and at that time, the ancestors had two powerful sea clan helpers, one was the dragon king and the other was coral.

And the portrait in the classics seems to be somewhat similar to the woman in front of him!

The fat king swallowed his saliva and asked cautiously.

"Your Excellency, do you know coral?"

Sonia's expression darkened, "Coral is my past name, and your ancestors should know this. ”

The fat king set off a storm in his heart, this sea woman is coral?

Isn't that at least a thousand years old?

He looked at the human man standing in the center of the strange army, clearly the leader.

Able to conquer a Sea Clan woman who has survived for thousands of years, and with such a large number of powerful troops, this man must be an extremely terrifying existence.

"Have you thought about it? Hand over the king's token, and we'll retreat. ”

The fat king is not stupid, he just needs something that only has a symbolic meaning from him, and he takes it.

"I do!"

Soon, the gates opened.

The fat king walked out with a big belly, holding a wooden box in both hands, and came to Sonia tremblingly.

Said with a flattering face.

"This is the king's token, please accept it."

Sonia casually opened the wooden box, and a white crystal lay quietly in the red silk cloth, emitting a misty light.

She nodded and closed the box.

The fat king looked left and right and asked carefully.

"Your Excellency Sonia, I don't know where Your Excellency Ji Chen came from? Is it the depths of the ocean? ”

"You don't need to care about this, you just need to know that this world is already the property of Lord Ji Chen, you just need to warn your descendants and subjects to live and work in peace and contentment as before, and you don't have to worry about killing yourself."

Sonia's cold words made his face pale, and he quickly nodded, "I will definitely remember it!" ”

He wasn't very interested in any of that anyway, as long as he was sure that these terrible armies wouldn't come here again.

Sonia watched the fat king, who could barely walk, return to the city, closed the city gate, turned around and returned to Ji Chen, and presented the plane key.

"My lord, live up to your mission."

Ji Chen bowed slightly, suppressed the excitement in his heart, picked up this plane key, and took out the one he had obtained earlier from his backpack, and put it together to look at it.

Faintly, he could feel that there was a close connection between the two plane keys in his hand, as long as they were placed in the arch and the outside world respectively, this secret realm could have a stable connection with the main world, and then generate a stable secret door.

At this point, he completely relieved his heart, and a smile appeared on his face.

The entire Great Fluorescent Sea will belong to the crown of the ocean, and it contains a whole secret realm, whether it is bright or secret, and the wealth will belong to the crown of the ocean.

As for this weak human kingdom, as he promised before, as long as they don't do anything and live in peace and contentment, he doesn't bother to pay attention to it.

Ji Chen put away the two plane keys, no longer delayed time, and waved his hand.

"Let's go!"

At the sound of an order, the army returned to the sea again, found the cave and returned the way it came.

Return to the Fluorescent Forest.

"At that time, the secret realm will be connected to the main world, which may cause some visions, Sonia, I want you to take the Sango Palace army to stabilize the hearts of the people of the Great Fluorescent Sea."

"This will be an important backup base for the future of the crown of the sea, and there is no room for error."

"This is the task I gave you."

Sonia nodded seriously, "Follow your will." ”

She has now completely entered the role of a subordinate, and when she heard the order, there was still some familiarity in her heart, as if she had returned to the appearance of being ordered to do things by those humans thousands of years ago.

Let her feel a little nostalgic and a little happy.

After such a period of experience, Sonia was sure that Ji Chen was an ambitious lord with a long-term vision and ability, and to be able to meet such an eloquent lord so well, she naturally had to take advantage of the opportunity.

Seeing that Sonia did not have a trace of arrogance at all, Ji Chen also nodded with satisfaction, a red inheritance-level hero unit was also one of his biggest gains from this trip.

And he is also a hero with a wealth of management, commanding and combat experience, which cannot be bought with money.
