Carmen Alicia and Miria and Rihanna managed to get out of the barrier, and after continuing on their way, they found a small stone castle.

The stone fort is small in size, but it looks very solid, it is built in the middle of the swamp, surrounded by swamps on all sides, and there is a drawbridge at the main entrance of the stone fort, but the drawbridge is now hanging high.

"This is it, Mr. Morro's stone castle. ”

Rihanna still remembered this stone castle, although she had never stepped out of the stone castle, but she still remembered it clearly, Alicia and Miria were very excited to hear Rihanna say this, and they finally arrived at their destination.

Alicia walked at the front, while Miria and Rihanna separated from her, and the three of them came to the front of the Stone Castle Drawbridge, which was a large swamp in front of them, impassable.

Just as the three of them were at a loss, the drawbridge suddenly and slowly lowered, and Alicia guessed that Moro must have known that they were here.

"Why haven't the children from the Free Frontier entered my humble stone castle?"

Out of nowhere, a voice came, and Rihanna immediately became excited, she heard that it was Moro's voice, Rihanna nodded at Alicia, and Alicia took Miria and Rihanna into the stone castle.

Crossing the drawbridge and the gate, everyone came to a hall, and in the center of the hall, stood an old man who felt that he was getting old, he had a long white beard, dressed in a gray robe, and looked at Alicia and the others with a smile on his back.

"Mr. Morro!"

Rihanna excitedly stepped forward and hugged Moro, who also smiled and touched Rihanna's head, like a grandfather treats his granddaughter.

"You little girl, I told you not to come again, but you brought someone else with you, what is it for me to say you well?" Moro suddenly glared at Rihanna with a dissatisfied expression, and Rihanna just smiled and stuck out her tongue.

"Teacher Moro, don't blame Rihanna, I asked her to bring us here. Alicia bowed, then whispered.

Moro looked at Alicia, then at Miria behind Alicia, then smiled slightly, and stroked his beard with his hand.

"You're Carmen Alicia, the Night Queen of the Free Frontiers, and that Winged Man must be Miria from Venice Yar. Moro said with a smile, Alicia smiled and nodded, while Miria was taken aback.

"Teacher Moro is really powerful, now that you already know our identity, then presumably the purpose of our coming here is also clear to you. Alicia whispered.

"You're going to deal with the sea monsters in the Black Snake Sea, right?" Moro asked with a smile.

"It's not just about dealing with those sea monsters, it's about finding the root cause and solving the root of the problem. Alicia said with a smile, which made Moro nod slightly.

"Your Free Frontier is finally no longer a stupid way to treat the symptoms but not the root cause. Moro said with a chuckle.

"I hope that Mr. Moro will give him advice. ”

Alicia said softly, and Moro waved his hand, he no longer spoke, but turned around and walked up the stairs, Alicia and the others looked at him with a puzzled face, I don't know what he thought in his heart, Moro turned around, saw Alicia and the others stunned in place, so he waved to them, and then turned back and continued walking, while Alicia and the others immediately understood, and quickly followed Moro.

Alicia and the others followed Moro through the stone castle, there are many rooms in the stone castle, Rihanna knows that many rooms here are Moro's laboratories, and the purpose of the experiment in each room is different, including the study of various creatures in the Yarrow continent, the study of various environments, and even a room full of human specimens, which is really chilling.

Finally, Moro stopped at the door of an azure room, he gently opened the door of the room, and walked inside, while Alicia and the others followed Moro into the room.

This room is obviously a research room for the study of the various seas and sea creatures in the continent, and on the table in the center is a large fish tank, with black sea water inside, which makes the tank blurry and not visible.

"This is the center of the Black Snake Sea. Moro said softly, which surprised Alicia and the others, and the three of them gathered around and carefully looked at the black sea water on the tank.

Suddenly, in the dark water, an eye opened, which made Miria, who was looking at the tank, take a few steps back and fall.

"What...... What's in there?" Miria asked with a trembling voice.

"Oh, I think that eye belongs to the Black Snake Troll. Moro said with a smile.

"What do you mean...... This cylinder ...... Is it the Black Snake Sea, actually?" Alicia felt incredulous, but she was truly impressed by this unknown magic.

"This is an simulacrum, the general simulacrum is just a simulate with living things, and I have achieved a simulacrum of the environment after years of research, the area inside this tank is the Black Snake Sea, it is actually still in the distant free frontier, what you see here is just a simulated scene. Moro said triumphantly.

"Oh my God, it's amazing, I'm sure the best teachers at Kerr City will be amazed by this simulacrum technique. Rihanna said excitedly.

"Hmph, how could that group of fools in Kerr's City have studied such great magic. Seeing Rihanna mention the city of Kerr, Moro said with a disdainful expression.

"Indeed, the mages of Kerr's City are all practicing magic in a step-by-step manner, and in terms of groundbreaking, they will certainly not be your opponent of Mr. Moro. Alicia nodded and whispered.

"Opponents, huh, they deserve to be my opponents, too?"

Moro obviously looked down on the mages of the Kerr Academy, and Alicia also felt Moro's pride from this, so in order not to touch his emotions, Alicia shook her head at Rihanna and motioned not to mention the mages of the Kerr Academy.

"Did you find anything from your research into the Black Snake Sea?" asked Alicia softly.

"Little Ellie, can I call you that?" Moro said softly, and Alicia nodded and smiled slightly.

"Where do you think the sea monsters in the Black Snake Sea come from?" Moro suddenly asked again.

"Hmm...... Isn't it from the Black Snake Sea?"

"Ha, many people think so, but according to my research, these sea monsters in the Black Snake Sea Sea don't belong to Siris at all!" Moro said with a smile.

"What do you mean...... They don't belong to the main material realm at all?" Alicia asked, her eyes widening in disbelief, Moro's argument was too much to believe.

Moro nodded slightly, and then he stroked the vat, and the vat suddenly brightened, and the appearance in the vat made Rihanna can't help but scream, and Alicia and Miria also frowned, looking at everything in front of them.

In the vat, it is obviously a simulacrum of the interior of the sea in the center of the Black Snake Sea, where there are all kinds of large sea monsters, in the three areas, there are also the legendary three giant sea monsters, the Black Snake Monster, the Dragon Covering the Sea, and the Hydra Monster, they are separated in three areas, and these three giant sea monsters must be the kings of the Black Snake Sea area.

Sea monsters are all over the Black Snake Sea, and in the center, there are no sea monsters close, the bottom of the center, is actually a castle, the castle in the sea, it seems that it has been abandoned for a long time, the walls of the castle, are full of various marine parasites, and the castle inside can not be known, but the castle always emits a faint red light.

"This is the underwater city of Athals, an ancient city that was once famous for its splendor. Moro whispered.

"I've heard of Athals, it's said to have been mysteriously destroyed for years, and I didn't think its original location was in the Black Serpent Sea......" Alicia said excitedly, obviously curious about these things.

"Mysterious annihilation?ha, that's just the stupid self-inflicted evil of the people of Athals, they want to rule the entire continent of Athal, so they launched a forbidden summoning, who would have thought that they would attract monsters from other planes that are enough to destroy the famous monsters of Athals, and Athals was submerged in the ocean, and the sea monsters ruled the area. Moro said his conclusion, and Alicia sighed softly, she couldn't imagine that there were so many stories about the Black Snake Sea in it.
