Genius in the whole system: The useless young lady dominates the world

The air was filled with a strong, salty smell, and the ground was covered with soft white sand. In the distance, the azure sea met the sky, sparkling and breathtaking.

This is the Fantasy Sea Continent, a world dominated by the sea, inhabited by all sorts of sea creatures: dragons, mermaids, merfolk, sea monsters, fishmen, turtles, crabs, jellyfish, sea snakes... the list goes on and on, together forming the unique ecosystem of this continent.

The three of them appeared on a rocky coastline. Not far away, several figures caught Lu Lingxi Yao's attention.

“Look, what are those?” Feng Qingxue asked, pointing to the figures.

The group stared intently and saw several figures dressed in sea-blue robes, with fin-shaped ears, fair skin, and beautiful features. The women were alluring and the men were exceptionally handsome, exuding a captivating aura with every gesture.

Bai Ze said calmly, "It's a sea monster. Rumors say sea monsters are evil, but it seems that's not entirely true."

Lu Lingxi Yao's gaze fell on the patrolling sea monsters. A thought struck her: the appearance of these sea monsters was somewhat similar to that of the sea monster she had contracted with—Lan Yuan. Could it be that Lan Yuan had some connection with them?

Thinking of this, Lu Lingxi Yao summoned Lan Yuan, who transformed into human form, wearing a light blue robe, with handsome features and a cold temperament.

"Lan Yuan, look at those sea monsters, aren't they just like you..."

Before Lu Lingxi could finish speaking, the patrolling sea monsters spotted them.

"Who goes there?!" a siren shouted sharply, his eyes warily scanning Lu Lingxi and her group, as well as the suddenly appearing Lan Yuan.

"We are..." Lu Lingxi was about to explain when she saw that the sea monsters had already drawn their weapons, looking ready to fight.

"Stop talking nonsense! You're acting suspiciously; you're obviously not good people! Come with us!"

Feng Qingxue immediately exploded, "Hey! Are you guys being reasonable?! We didn't do anything, why are you arresting us!"

"Enough talk! Take him away!"

Before Lu Lingxi, Yao, and the others could react, they were surrounded by the sea monsters and forcibly taken away. After being taken to the sea monster's territory, they were locked in a cage made of coral and seashells.

Feng Qingxue sat on the seashell, fuming, and complained, "What bad luck! I was captured for no reason. These sea monsters are so unreasonable!"

Bai Ze closed his eyes to rest, seemingly unconcerned about the current situation.

Lu Lingxi looked at Lan Yuan with some worry in her heart, "Lan Yuan, are you alright?"

Lan Yuan shook his head. "I'm fine."

Just then, a siren dressed in magnificent attire walked in; it was the siren captain who had captured them earlier.

"Who are you? What are you doing here in our Siren Clan?" the Siren captain asked coldly.

Lu Lingxi explained, "We just wandered into this place by mistake, we meant no harm. We..."

Captain Siren interrupted her, "Shut up! Do you think I'd believe your lies? Speak! Are you spies sent by the Seahorse Clan?"

"Seahorse Clan?" Lu Lingxi was taken aback for a moment, then realized that there seemed to be some kind of conflict between the Sea Demon Clan and the Seahorse Clan.

"We really aren't spies!" Lu Lingxi tried to explain, but the Siren Captain wouldn't listen and turned to leave the cage.

Feng Qingxue asked anxiously, "What should we do? These sea monsters won't listen to our explanations at all!"

Lu Lingxi Yao pondered for a moment and said, "It seems we need to find a way to prove our innocence."

At this moment, Lan Yuan suddenly spoke up and said, "I'll give it a try."

Lan Yuan walked to the edge of the cage and said to the sea monster guards outside, "I want to see your king."

The siren guards were taken aback for a moment, then burst into laughter.

"You think you can see our king? You're dreaming!"

However, Lan Yuan ignored their mockery and instead released a trace of the aura belonging to the Sea Demon King. Sensing this aura, the laughter of the Sea Demon guards stopped abruptly, and their faces turned pale instantly.

"This...this is...the aura of royalty?!"

One of the siren guards hurriedly ran in to report, and a moment later, a dignified and noble siren came out; it was none other than the siren king.

The Sea King looked at Lan Yuan, his eyes filled with shock and excitement.

"You...you are...Ling Yu?!"

Lan Yuan looked at the Sea Demon King and nodded slightly. For some reason, upon entering this land, his blank memories were instantly filled in.

"It really is you! My child! You've finally returned!" The Sea King rushed forward excitedly and hugged Lan Yuan tightly.

Seeing this, Lu Lingxi and the others were stunned. They never expected that Lan Yuan would be a prince of the Sea Demon Clan!

However, at that moment, a cold voice rang out.

"Father, don't be fooled by him! How could he possibly be Yu'er's younger brother?"

A siren dressed in a black robe slowly walked over, staring at Lan Yuan with a sinister look in his eyes. He was the eldest prince of the siren clan, Lan Yuan's brother, Ling Yun. His appearance instantly froze the previously relaxed atmosphere, and the air was filled with a tense atmosphere.

Lan Yuan frowned slightly. He hadn't expected Ling Yun to appear at this time. He had intended to explain slowly, not wanting to cause any unnecessary trouble. He glanced coldly at Ling Yun, his tone carrying a hint of warning.

"Ling Yun, you'd better not talk nonsense."

Ling Yun sneered, his eyes filled with disdain. "Nonsense? Father, look at him! A human of unknown origin dares to impersonate my brother Yu'er! He's incredibly audacious! I suspect he's a spy sent by a foreign race, intending to harm our sea demon clan!"

The Sea King hesitated. He looked at Lan Yuan, then at Ling Yun, and couldn't make a judgment for a moment. Although Lan Yuan's appearance was similar to that of his young son, many years had passed, and he couldn't be completely sure.

Seeing this, Lu Lingxiyao stepped in front of Lan Yuan, looking directly at Ling Yun without fear: "Your Highness, you can eat whatever you want, but you can't say whatever you want! Whether Lan Yuan is your little prince or not is not for you to decide!"

"Ling Yun, if you dare to slander Lan Yuan again, don't blame me for being impolite!"

Feng Qingxue also stepped forward, her body engulfed in raging flames, radiating a powerful aura. The Phoenix Clan has always been protective of its own, so she naturally wouldn't stand idly by while Lan Yuan was wronged.

Ling Yun was intimidated by Feng Qingxue's imposing aura and took a step back, but he quickly regained his composure. He smiled coldly and said, "What? Are you feeling guilty? Why are you protecting him like this? Are you in cahoots with him?"

Bai Ze remained silent, quietly observing the situation. He had a vague feeling that something was wrong; Ling Yun's reaction was too intense, as if there was something else going on.

Seeing that the two sides were deadlocked, the Sea King finally chose to believe Ling Yun. After all, he was his eldest son, who had been intelligent and sensible since childhood and had earned his deep trust. He waved his hand and ordered the guards to take down Lan Yuan and the others.

"Father, do you really believe Ling Yun but not me?" Lan Yuan looked at the Sea Demon King with disappointment, his eyes filled with pain.

The Sea King didn't speak, he just turned his head away. He didn't want to do this either, but he couldn't take the risk. The guards rushed forward and surrounded Lan Yuan, Lu Lingxi Yao, Feng Qingxue, and Bai Ze. Lan Yuan didn't resist. He knew that resisting now would only make things worse.

Lu Lingxi and Feng Qingxue refused to surrender and fought back fiercely, but they were ultimately outnumbered and subdued by the guards.

Bai Ze still didn't make a move. He just watched everything coldly, having already made his decision. The group was escorted to the Sea Demon Clan's prison. The dark and damp cell was filled with a rotten smell.

"Lan Yuan, are you alright?" Lu Lingxi asked Lan Yuan with concern.

Lan Yuan shook his head, forcing a smile, "I'm fine, but I've dragged you all into this."

Feng Qingxue patted Lan Yuan on the shoulder and comforted him, "Don't talk about being implicated, we're in this together! Don't worry, we'll definitely find a way to get out."

Bai Ze walked to the cell door, carefully observing the surroundings, looking for an escape route.

"Bai Ze, what are you doing?" Lu Lingxi asked curiously.

"Shh!" Bai Ze made a shushing gesture, signaling them to be quiet.

He pointed to an inconspicuous crack in the cell wall and whispered, "I've found a secret passage; perhaps we can escape from here."

Lu Lingxi and Feng Qingxue looked in the direction Bai Ze was pointing and indeed found a narrow gap. The gap was hidden in the shadows of the wall and would be difficult to spot without careful observation.

Lu Lingxi said excitedly, "Really? That's great! Let's escape quickly!"

Bai Ze shook his head and said, "This passage is too narrow. I'm afraid it would be difficult for the four of us to pass through at the same time. Moreover, I suspect there are traps in this passage, and it could be very dangerous to enter rashly."

"What should we do then?" Feng Qingxue asked anxiously.

Bai Ze pondered for a moment and said, "How about this, I'll go in first to scout ahead, and if it's safe, I'll come back to get you."

Lu Lingxi immediately objected, "No! It's too dangerous. We can't let you go on this risk alone."

“Yes, Bai Ze, let’s think of another way together,” Feng Qingxue also advised.

Bai Ze felt a warmth in his heart when he saw their worried eyes. He smiled and said, "Don't worry, I'll be fine. I'm proficient in the art of Qimen Dunjia, so this little trick won't stump me. You wait here for me, I'll be back soon."

After saying that, Bai Ze slipped into the narrow crevice and disappeared into the darkness.

Lu Lingxi and Feng Qingxue waited anxiously, their hearts filled with worry. The cell was silent, with only the sound of the sea crashing against the rocks, which sounded particularly dull.

Just then, a rustling sound came from the crack, growing closer and closer, like some kind of creature crawling.

Lu Lingxi gripped her longsword tightly, while a faint golden flame ignited around Feng Qingxue. Lan Yuan paced anxiously back and forth, muttering to himself, "Will everything be alright...? Bai Ze will be alright, won't he..."

Suddenly, a dark figure darted out from the gap and pounced on Lan Yuan! Lu Lingxi reacted quickly, pushing Lan Yuan aside, but she herself was caught in the crossfire.

The longsword slashed through the air, but only a metallic clang was heard. By the light of Feng Qingxue's flames, they could see the dark shadow clearly—a giant crab, its entire body black, gleaming with a metallic luster, its two enormous pincers as if cast from steel, which was terrifying.

Lan Yuan exclaimed, "Ironclad Crab! These are elite sea monsters guarding this important place, how could they be here?"

Before they could think further, more armored crabs poured out from the gaps, surrounding them. Lu Lingxi and Feng Qingxue stood back to back, watching these ferocious-looking monsters warily.

"It seems someone doesn't want us to leave alive," Lu Lingxi said with a cold laugh, the long sword in her hand gleaming.

Feng Qingxue snorted coldly, and the golden flames instantly surged, forcing the surrounding armored crabs back a few steps. "Want to silence them? They'll have to see if they have the ability!"

Lu Lingxi Yao's longsword struck the Ironclad Crab's hard shell heavily, trying to find its weakness. Feng Qingxue's flames scorched the Ironclad Crab's body, while Lan Yuan, while dodging the attacks, manipulated water elements to launch an offensive against the Ironclad Crab.

However, the number of armored crabs was large, and they kept emerging from the gaps. Lu Lingxi and Feng Qingxue gradually felt their strength failing, and their wounds increased.

Lu Lingxi bit her lip tightly, "Damn it! If this continues, we'll be dragged down by them!"

Just then, Bai Ze's voice came from the gap: "Come quickly!"

Lu Lingxi and Feng Qingxue exchanged a glance, then seized the opportunity and rushed toward the gap. Lan Yuan did not dare to slack off and followed closely behind, staggering.

Passing through the narrow gap, they arrived at a more spacious area, where Bai Ze stood holding a glowing bead that illuminated the surroundings.

“This is…” Lu Lingxi Yao looked at her surroundings and couldn’t help but be stunned.

This is a huge cave, with countless luminous pearls embedded in its walls, illuminating the entire cave as if it were daytime. In the center of the cave, there is a huge altar, covered with ancient texts, exuding a mysterious aura.

Bai Ze explained, "This is a forbidden area of ​​the Sea Demon Clan, and also the place where Ling Yun colluded with other races."

"Foreigners?" Lu Lingxi asked in confusion.

Bai Ze nodded. "That's right. In order to usurp the throne, Ling Yun colluded with the Deep Sea Demon Clan, attempting to use their power to control the entire Sea Demon Clan."

Feng Qingxue exclaimed, "Deep Sea Demons? The infamous Deep Sea Demons, those who are rumored to be bloodthirsty and incredibly cruel!"

Lu Lingxi's eyes were resolute, "We absolutely cannot let them succeed!"

Lan Yuan asked, "But what should we do now? There are only four of us. How can we fight against the powerful demons and Ling Yun's army?"

Bai Ze smiled mysteriously: "Don't forget, this is the forbidden area of ​​the sea monster clan, where many secrets are hidden." He walked to the altar and placed the bead in his hand into a groove.

Suddenly, the entire cave shook, the writing on the altar emitted a dazzling light, and a huge light screen appeared in front of them, displaying a scene—in front of Ling Yun, a semi-transparent black sphere floated in the air, and inside the sphere, a twisted human figure could be vaguely seen, exuding a chilling dark aura. It was a projection of the deep-sea demons, continuously transmitting power to Ling Yun.

Bai Ze's expression was solemn. "They are performing a blood pact ritual! Once the ritual is complete, Ling Yun will gain the power of the Demon Clan, and then no one will be able to stop him!"

Lu Lingxi and the others held their breath and stared intently, not daring to make the slightest sound. Feng Qingxue looked worriedly at the shimmering light screen, "But how do we get in? This light screen is like a tortoise shell; we can't get through at all."

Bai Ze raised his slender finger and pointed to a mysterious rune in the center of the altar. "Destroying that rune will break the barrier."

Lu Lingxi and Feng Qingxue exchanged a glance and immediately sprang into action. Lu Lingxi moved with lightning speed, her long sword hurtling towards the altar, while Feng Qingxue followed closely behind, red flames trailing a dazzling tail of light behind her.

However, just as they were destroying the runes, the sand around the altar suddenly surged, and a group of giant armored crabs emerged from the sand, waving their sharp claws and blocking their path.
