In an instant, numerous warships surrounded Yu Kai's area like an iron barrel, completely impenetrable. The largest warship slowly approached from behind, two large flags hoisted high, the characters "Wen" and "Li" written in a flamboyant style, roaring fiercely in the fierce wind, as if arrogantly displaying the ship's master's authority.

Yu Kai stood steadily above the island, his expression calm and composed, his resolute face showing no sign of panic, like a towering, indestructible peak.

Wen Chengzhi, Wen Qiluo, Li Yifeng, Li Mengli and others walked to the bow of the ship. They looked down from above, with arrogant faces and sharp eyes, staring intently at Yu Kai, who was riding a mecha below.

"Are you Yu Kai?" Wen Chengzhi's face was gloomy, and his voice was like the water in a cold pond, icy and chilling.

"Yes!" Yu Kai was neither humble nor arrogant, his voice was clear and heroic, echoing slowly on the sea.

"How are my generals doing now?"

"If you force them, they will surely die! If you don't pursue the matter further, I might consider letting them go!"

"How can you negotiate with me?" Wen Chengzhi frowned, his face full of anger.

"Their lives are in my hands. I know their status in their respective families. I am worthless, so the decision is up to you."

"Are you threatening me?" Wen Chengzhi's eyes were wide open, and the rage in his eyes was blazing, as if it was about to burst out and burn Yu Kai to ashes.

"You may think so! If your arrogance causes their lives to be in danger, I'm afraid you will have a hard time explaining it."

"Do you think you're the only one who doesn't fear death? I'm the same and never accept threats from others. Li Yifeng, obey your orders!"

"I am here!" Li Yifeng hurriedly bowed his hands, his expression solemn and dignified, not daring to slack off at all.

"Go meet him! Let him know that the majesty of heaven cannot be violated."

"Yes!" Li Yifeng received the order and leaped into the air. A long, cold mace flashed in his hand, and he stepped into the air, slowly approaching Yu Kai. With each step he took, the pressure he unleashed grew stronger, like a mountain crashing down, nearly suffocating him. The air around him became heavy and stagnant.

Yu Kai's face was solemn, knowing full well that these men were exceptionally powerful. He drew his sword, and a powerful pressure instantly erupted from his body to counteract them. The air around him crackled and crackled, as if ready to collapse at any moment. The tense atmosphere was so intense that it made one's heart ache, and one's breathing became rapid and disordered.

"Kill!" Li Yifeng roared, his voice resounding through the heavens, a roar that seemed capable of cracking the very air. Instantly, he manifested two heads and four arms. In one right hand, he held a spear gleaming with cold light, its tip flashing with a chilling icy gleam. In the other, he grasped an impossibly sharp steel fork, its spikes brimming with fear. He charged at Yu Kai with furious force, his moves swift and ruthless, each blow a killing blow, as fierce and ferocious as a hurricane.

Yu Kai, without hesitation, swung his sword, his figure swift as lightning, engaging Li Yifeng in a fierce clash. For a moment, the two sides exchanged blows, weapons clashing in the air, sending forth brilliant sparks like bursting stars. Powerful air currents swept through the surroundings, shaking the warships violently and forcing them to retreat. The sea surface erupted in layers of raging waves, resembling the galloping of thousands of horses, a majestic spectacle.

"Hmph, let's see how long you can hold on!" Li Yifeng's attack became more and more fierce. The three heads roared in unison, the roars were deafening, and the six arms waved their weapons and attacked in turns, weaving an impenetrable attack net, suppressing Yu Kai so much that he had almost no chance to breathe.

Yu Kai gritted his teeth, his eyes were as firm as iron, and he danced the long sword in his hand with great force. His body kept flashing, cleverly avoiding the fatal attacks again and again, while waiting for an opportunity to counterattack. Beads of sweat rolled down his forehead like rain.

The battle between the two intensified, until the only sounds between heaven and earth seemed to remain: their figures and the roar of their weapons clashing. The sound was earth-shattering and terrifying. As time passed, Li Yifeng's relentless attacks gradually wore away. His breathing became erratic, and beads of sweat covered his forehead. Yu Kai seized the opportunity to infuse his sword with mysterious spiritual energy. The blade instantly shone with a dazzling light, like a blazing sun. He slashed with all his might. "Puff!" Li Yifeng's sword was instantly severed, his fierce momentum undiminished. Immediately, Yu Kai severed half of his head.

"Ah!" Li Yifeng screamed, his face filled with pain and terror, his features distorted beyond recognition. He quickly distanced himself from Yu Kai. Everyone was shocked. How could he, who had just had the upper hand, suddenly be beheaded by Yu Kai? This huge reversal made everyone present gasp, and everyone's face was filled with shock.

"This Yu Kai is really unpredictable!" Wen Chengzhi was about to order Li Mengli to take action, but saw that she could not wait to rush towards Yu Kai.

Just as Yu Kai was about to continue his pursuit, a young woman flew out from the warship. Her figure was graceful and elegant, like a dancing fairy. Her face was beautiful yet cold, like a plum blossom blooming proudly in the snow in the dead of winter. A mysterious mirror in her hand shot a stream of light towards him.

He twisted and turned in the air to dodge, but the streak of light was like a thorn in his flesh, and Yu Kai was secretly shocked. He directly used the law of space to rush towards Li Yifeng. Because he did not understand the mystery of the mirror, he did not dare to touch the streak of light easily.

Just as the two lieutenants stepped forward to support Li Yifeng and prepare to retreat, Yu Kai appeared behind them like a ghost. He swung his sword fiercely, and a sharp blade light whistled out like a roaring dragon. The three of them were instantly alarmed and turned to resist with all their might, but they were still knocked back by the powerful sword light. Their armor was shattered, and their bodies were covered in blood, a horrible sight.

Instantly, several more lieutenants flew out, their expressions tense and their movements swift. They quickly escorted Li Yifeng and the others back to the warship. At this moment, Yu Kai was caught off guard by the streak of light, his figure suddenly frozen. Luo Yingxue's voice echoed in his mind: "Yu Kai, you disappoint me so much. How did you become a mutant? You disappoint me so much."

Yu Kai's face was filled with anxiety, beads of sweat dripping down his forehead. He had already fallen into a dream, and within it, he kept explaining things to his mother, his voice trembling and anxious, like a helpless child. But Luo Yingxue's face remained impassive, unmoved. "How could you wreak havoc in the underworld for a mutant? How dare you become an enemy of Heaven? I'm so disappointed that I don't have you as my son. You don't need to live on in this world any longer!"

Yu Kai's eyes sank into despair. His once resolute gaze dimmed, and his aura waned dramatically. He muttered, "I've disappointed my mother. I was wrong. There's no point in living anymore!"

Li Mengli used the Mind Mirror to firmly control Yu Kai with one hand, and with the other, she swung a sharp flying knife straight at Yu Kai's face. The flying knife flashed a cold light in the air, carrying a deadly threat, as if to put Yu Kai to death.

Just as the flying knife was about to pierce Yu Kai's face, Niuniu let out a delicate cry, her voice like a silver bell, and transformed into a dark shadow, sprinting towards him. Her eyes were sharp, and with a swipe of her sword, she knocked the flying knife away. With a crisp "ding!", it flew into the distance and disappeared.

She landed in front of Yu Kai, her clothes fluttering in the wind like a gorgeous blooming flower. While keeping an eye on Li Mengli, she called out to the distraught Yu Kai, "Brother! Brother! Wake up! What's wrong with you?" Her voice was filled with anxiety and worry.

"He is trapped in the Mind Mirror and no one can wake him up now. If he can't break free, he will surely die!" Li Mengli said coldly to Niu Niu, and then quickly shot out two flying knives, which flew towards Yu Kai and Niu Niu with the wind.
