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

"Damn it!" Lu Lingxi cursed under her breath, brandishing her longsword with a rainbow-like light, cleaving several armored crabs that charged at her in two.

However, the Ironclad Crabs were numerous and fearless, surging forward one after another, surrounding her like a tide.

Upon seeing this, Feng Qingxue immediately cast a spell, and the red flames transformed into a giant fire phoenix, rushing towards the crab swarm. Wherever the fire phoenix passed, the armored crabs were charred black.

"Let me help you!"

Bai Ze flashed into the midst of the crab swarm, a crystal-clear jade flute appearing in his hand. The melodious flute music, carrying a strange magic, caused the previously ferocious armored crabs to gradually slow down, their eyes becoming dazed.

Lan Yuan watched Bai Ze's retreating figure, his heart filled with doubt. He always felt that Bai Ze was hiding many secrets. The mysterious flute music and the unfathomable strength made him feel a sense of awe.

Lu Lingxi Yao's sharp gaze swept across the altar as she analyzed the current situation. "Bai Ze, how long can your flute music control those armored crabs?"

Bai Ze held a white jade flute in his hand, his face solemn. "At most, we can only hold on for another quarter of an hour. The flute's control over them is getting weaker and weaker."

“A quarter of an hour…” Lu Lingxi Yao hesitated for a moment, “That’s enough.”

She turned to look at Lan Yuan, "When Bai Ze's flute music stops, that's our chance to act. Remember, our goal is to disrupt the ritual, not to kill Ling Yun."

Lan Yuan held his trident firmly, his eyes resolute. "I know I won't let him succeed!"

Lan Yuan flashed forward, blocking Lu Lingxi and Feng Qingxue, his trident pointing directly at Ling Yun. "Ling Yun, you colluded with the Deep Sea Demon Clan and harmed your clansmen. Your crimes are unforgivable!"

Ling Yun's expression changed slightly. He suddenly opened his eyes, a sinister glint flashing in them. "Ling Yu, how dare you..."

"What wouldn't I dare!" A resolute light flashed in Lan Yuan's eyes. "Today, I will rid the sea monster clan of you, you scum!"

As soon as Lan Yuan finished speaking, Bai Ze's flute music stopped abruptly. The armored crab, which had been controlled by the flute music, seemed to wake up from a dream and became ferocious again. It brandished its huge pincers and charged towards Lan Yuan and Ling Yun. In an instant, the cave was in chaos.

"Now!" Lu Lingxi shouted, instantly rushing towards the six-pointed star array in the center of the altar. The long sword in her hand was aimed directly at Lingyun, the eye of the array.

Feng Qingxue followed closely behind, spreading her wings and transforming into a fiery red streak of light. The scorching flames swept out, burning the armored crab blocking her way to ashes.

Bai Ze quickly pulled out a handful of talismans from his pocket, chanting incantations. The talismans transformed into beams of golden light, trapping some of the smaller armored crabs.

Lan Yuan was locked in combat with Ling Yun, wielding his trident with great skill and power, each attack carrying a sharp gust of wind that forced Ling Yun to retreat repeatedly.

"Ling Yu, do you really think you can stop me?" Ling Yun roared, and a surge of black demonic energy suddenly erupted from his body. His power instantly surged, and he sent Lan Yuan flying with a single palm strike.

"Lan Yuan!" Upon seeing this, Lu Lingxi Yao's heart tightened. She knew that Ling Yun had obtained some of the power of the Deep Sea Demon Clan, making him even more difficult to deal with.

"Master, don't worry about me, quickly destroy that ritual!" Lan Yuan struggled to his feet and rushed towards Ling Yun again.

Lu Lingxi gritted her teeth and swung her longsword even more swiftly, unleashing a barrage of sword energy that swept towards the six-pointed star array like a storm.

At this moment, a sudden change occurred.

The black sphere suspended in the air suddenly trembled violently, emitting a piercing scream. The projection of the deep-sea demon inside the sphere became clearer, and it stretched out its twisted claws to grab at Lu Lingxi Yao.

"Watch out!" Feng Qingxue exclaimed, and a barrier of flames appeared in front of Lu Lingxi Yao, blocking the attack of the demonic claws.

However, the power of the demonic claw was unexpectedly strong. The flame barrier shattered instantly, and Lu Lingxi was blasted away, crashing heavily to the ground and spitting out a mouthful of blood.

"Yao Yao!/Master!" Feng Qingxue and Lan Yuan exclaimed at the same time.

Just at this critical moment, a figure suddenly appeared in front of Lu Lingxi Yao, blocking the attack of the demonic claws.

"Bai Ze!" Lu Lingxi Yao looked at the figure blocking her way in astonishment.

Bai Ze's face was pale, a trace of blood spilled from the corner of his mouth, the white jade flute in his hand was broken in two, and his body emitted a faint light.

“You…” Lu Lingxi Yao was filled with shock and emotion.

"Cough cough..." Bai Ze coughed weakly a few times, "I...I'm fine..."

"Bai Ze, are you crazy!" Feng Qingxue shouted anxiously, "You'll die if you do this!"

Bai Ze forced a smile, his gaze softening as he looked at Feng Qingxue. "Qingxue, I promised you... I would protect Yaoyao..."

Just then, the black sphere suddenly exploded, turning into a cloud of black mist and dissipating into the air. Ling Yun also let out a scream and collapsed to the ground, unconscious.

The ceremony was disrupted.

Lu Lingxi Yao quickly stepped forward to check on Ling Yun's condition. She found that he had only fainted and was not in any danger. She breathed a sigh of relief and turned to Bai Ze, asking worriedly, "Bai Ze, how are you?"

Bai Ze shook his head to indicate that he was fine, but his face was still frighteningly pale.

"Tie him up first." Lu Lingxi pointed to the unconscious Ling Yun. "We need to tell the Sea Demon King about this."

Feng Qingxue and Lan Yuan immediately took action, using specially made chains to bind Ling Yun tightly, while Lu Lingxi Yao supported the weak Bai Ze, and the group headed towards the Sea Demon Clan's palace.

Inside the palace, the atmosphere was heavy. The Sea Demon King looked at Ling Yun, who was bound hand and foot, and Bai Ze, who was pale-faced, with shock and confusion in his eyes.

"What exactly is going on?" the Siren King asked in a deep voice.

Lu Lingxi recounted the events in detail, including how Ling Yun colluded with the Deep Sea Demons in an attempt to enhance his strength through an evil ritual. She also presented the letters she found on Ling Yun regarding his correspondence with the Deep Sea Demons as evidence.

After reading the letter, the Siren King's face turned ashen, and he trembled all over. He never imagined that his son, whom he had always been so proud of, would do such a rebellious thing. He closed his eyes in pain, took a deep breath, and slowly opened them after a long while, his eyes filled with disappointment and grief.

“Father…” Lan Yuan stepped forward and called out softly. He knew that his father must be very sad at this moment.

Seeing the touching scene of the father and son reunited, Lu Lingxi and the others were also moved. The three of them exchanged glances in tacit understanding, and then quietly left the palace, leaving the space to the father and son who had been separated for so long.

“Ling Yu…” The Sea Demon King looked at Lan Yuan, a complex emotion flashing in his eyes.

Lan Yuan walked to the Sea Demon King's side, took his hand, and said softly, "Father, don't be too sad. My elder brother was confused for a moment, but I believe he will repent."

The Siren King shook his head and sighed, "Ling Yu, you are too kind. What he did has crossed the bottom line of the Siren Clan. I cannot tolerate it."

"Father..." Lan Yuan wanted to say something, but was interrupted by the Sea Demon King.

"Ling Yu, you've suffered all these years." The Sea Demon King looked at Lan Yuan, his eyes filled with guilt and pity. "Back then, I believed Ling Yun's words, thinking you were a fraudster who had impersonated someone else. I didn't give you any chance to explain before locking you up..."

Lan Yuan took a deep breath and told the Sea Demon King everything about his disappearance, which was also orchestrated by Ling Yun, his experiences over the years, how he met Lu Lingxi Yao, and how he became her contracted servant.

After hearing Lan Yuan's story, the Sea Demon King felt even more grief and self-reproach. He never imagined that he had been deceived by his own son for so many years, and had even missed the chance to recognize his younger son. He tightly grasped Lan Yuan's hand and said excitedly, "Ling Yu, my child, you've finally returned..."

The Siren King's emotions gradually calmed down. He looked at Lan Yuan and solemnly said, "Ling Yu, you are the rightful heir of the Siren Clan. I hope you can inherit the throne and lead the Siren Clan to a more glorious future."

Lan Yuan shook his head and said, "Father, I still want to train with Master to improve my strength. Besides, I have no interest in the throne."

Seeing the determination in Lan Yuan's eyes, the Sea King ultimately respected his choice. He nodded and said, "Alright, since you've made your decision, I won't force you. However, you will always be my child, the prince of the Sea King's clan, the future king of the Sea King's clan. I will wait here for your return."

"Thank you, Father," Lan Yuan said gratefully.

Just then, a commotion arose outside the palace. A guard rushed in, knelt down, and said in a trembling voice, "Report...reporting to Your Majesty, the deep-sea demon army is pressing in and has already breached the outer defenses..."
