I was so scared that I put all my points into health.

In that eerie space, the elven king dragon mage avatar carefully escorted the weakened Flint, their steps light and cautious, as if the slightest carelessness would disturb the unknown dangers lurking within this mysterious space. They moved slowly forward, each step steady and firm, until they finally returned to the solemn and majestic main hall.

The mysterious man in black silently followed them back to the main hall. He stood quietly to one side, like a silent statue, saying nothing, lost in his own thoughts. His figure appeared somewhat lonely in the shadows of the main hall, his slightly hunched back seeming to carry endless worries, a faint aura of regret like invisible threads gently entwining around him.

With his keen insight, the avatar of the Elf King Dragon Mage seemed to see through the man in black's appearance and discern his innermost thoughts at a glance. He said softly, "Even with the combined efforts of the Underworld Emperor, we were unable to completely trap him. He must have used some unknown method that we are yet to discover. That mysterious power is truly elusive."

At this moment, the man in black slowly removed his hood, gradually revealing his previously concealed face, which appeared slightly weary and forlorn. A deep sense of helplessness lingered in his eyes, as if concealing countless untold stories. His appearance truly evoked pity. It turned out that he had devoted immense effort to awaiting this decisive moment. Countless days and nights had passed, he had diligently cultivated, seizing every opportunity to improve himself, every drop of sweat a testament to his dedication and perseverance. However, fate seemed to have played a cruel joke at this crucial moment; all his efforts had vanished in an instant. The helplessness and disappointment of failing at the last hurdle made his expression even more desolate. Everyone couldn't help but wonder what deep-seated hatred existed between the black magician and the man in black that would drive the man in black to such a relentless pursuit of victory in this battle.

The man in black was the young man who had accompanied Wang Xiaoyi, Alpha, and Allen on their escort mission. The mission was only halfway complete when he left, yet he vanished without a trace. Afterwards, as he turned to leave, Wang Xiaoyi unexpectedly found the badge he had left behind. Wang Xiaoyi immediately examined it closely; the shimmering light and mysterious patterns on the badge piqued his curiosity. Then, Wang Xiaoyi activated a special skill and was astonished to discover that the young man before him had reached an astonishing level 70. To have leveled up so quickly was truly unbelievable. Everyone secretly wondered what miraculous method he had used to achieve such astonishing progress in such a short time.

Wang Xiaoyi had originally wanted to ask the man in black more questions to uncover the story behind him. But just then, Fulin's condition improved. Her tightly closed eyes slowly opened, and her pale face gradually regained some color. She was finally able to speak. Seeing this, Wang Xiaoyi instinctively shifted his attention to Fulin, first inquiring about her condition.

At this moment, Flint was still extremely weak, so weak that a gentle breeze could knock her over, but she was not in mortal danger. She weakly told Wang Xiaoyi that, just as she was drifting in and out of consciousness, the dark mage's deep, sinister voice had sounded in her ear, saying he wouldn't take her life, but only wanted to borrow her power. This surprised everyone present. After all, in everyone's impression, the dark mage had always been a cold-blooded, ruthless being who viewed life as insignificant. Now, however, he had taken a liking to Flint's cuteness. It was possible that Flint's adorable charm was irresistible even to the dark mage. Could the dark mage actually be a hidden "lolicon"? The moment this thought arose, everyone couldn't help but smile slightly.

While Wang Xiaoyi was still lost in thought, the battle on the Underworld Emperor's side was escalating. As the light of the magic circle grew increasingly dazzling, as if it were about to devour the entire world, that brilliant yet eerie light roared like a ravenous beast. Numerous strange and malevolent black magic artifacts slowly emerged from the magic circle.

Among them were colossal black demonic beasts, resembling towering mountains. Their bodies seemed to be forged from the hardest obsidian, emanating a dense demonic aura. This aura, like tangible black smoke, swirled and surged around their bodies. When their enormous, blood-red maws opened, they resembled a dark abyss that devoured everything. Their ferocious fangs gleamed coldly in the light, and each opening was accompanied by a chilling aura, as if they were about to mercilessly destroy all that was beautiful in the world.

There were shadowy figures, as elusive and silent as ghosts, flitting through the air as if they were messengers from the underworld, traversing between the realms of Yin and Yang. They emitted chilling, piercing screams that seemed to penetrate the soul, sending shivers down one's spine, as if one were in a cold, dark night, one's soul enveloped in endless fear.

There were also jet-black energy clusters, like bottomless abysses, their energy so dense it seemed almost tangible, radiating an aura of annihilation. The space around these energy clusters seemed to distort, as if to engulf everything in the world and reduce it to nothingness. Even from a distance, the powerful force exerted a profound sense of oppression, as if an invisible mountain was pressing down on one's heart, making it hard to breathe.

The Underworld Emperor descended like a god of war, charging into the enemy ranks with overwhelming force. The light emanating from him instantly illuminated the darkness, its radiance like the sun's glow, dispelling the surrounding darkness and evil. He seemed like a dazzling star descending to earth, his armor shimmering with a mysterious light, showcasing his majesty and power.

At this moment, he held a jet-black longsword, its blade radiating a chilling light that seemed capable of cutting through the air, making it impossible to look directly at him. With each swing of the longsword, it seemed as if it could sever the shackles of time and space. The Underworld Emperor exuded a boundless and majestic aura; his figure flashed, his speed so extreme that he was almost impossible to see clearly.

Beneath his longsword, the massive heads of the black demonic beasts were severed one after another, blood splattering and filling the battlefield with a bloody, stench. The black shadows before him were like ants trying to shake a tree, nowhere to hide. Their seemingly invisible forms were torn apart by the Underworld Emperor's fierce attacks, then vanished into thin air as if they had never existed. Those dark energy clusters, under the Underworld Emperor's powerful impact, instantly crumbled, turning into streaks of black debris that slowly dissipated like shattered dreams.

The Underworld Emperor's movements were fluid and seamless, without the slightest pause. Each swing of his blade was like a meticulously choreographed dance move, elegant yet deadly, as if performing a magnificent spectacle. Wherever he passed, all creatures of darkness were utterly annihilated, leaving not a single one alive. Finally, the Underworld Emperor sheathed his blade and stood still, his cold, stern face devoid of any emotion, as if what he had just experienced was merely a trivial matter. The darkness gradually receded, and everything seemed to return to calm, with only the lingering stench of blood and the smell of burning flesh reminding people of the fierce battle that had just taken place.

However, this tranquility did not last long. A new magic circle appeared in the sky, and as its light grew brighter, many strange and malevolent dark magic artifacts slowly emerged from it once more. Their appearance was like ripples breaking the calm, causing the previously peaceful atmosphere to tense up again.

The Underworld Emperor frowned slightly, muttering to himself, "Time magic?" These seemingly simple three words contained deep doubt and vigilance. Then, he swiftly and decisively slaughtered the group of dark magic creations with his blade, his movements still swift and resolute, without the slightest hesitation.

However, what was even more unexpected was that this situation repeated itself. Every time the Underworld Emperor destroyed these products of dark magic, new ones would soon reappear like ghosts, as if some mysterious force was manipulating everything from behind the scenes. The Underworld Emperor's expression gradually became irritable, and a trace of fatigue and helplessness began to appear on his originally cold and stern face.

At this moment, the Elf Dragon King (in human form) was patiently observing the situation. His gaze was like that of a sharp eagle, not missing a single detail. He keenly noticed an unusual fluctuation in one spot; it was the place where the small black ball the black mage had thrown at Wang Xiaoyi had exploded, emanating an unsettling, unknown energy. That energy seemed like an invisible vortex, drawing the Elf Dragon King's (human form) attention.

The Elf Dragon King (in human form) decided to investigate. He cautiously approached the place, each step light, as if afraid of disturbing the mysterious power within. He attempted to decompose it using elemental reduction. He gathered elemental power, and the surrounding light shimmered with an eerie brilliance. Under his control, the elemental power slowly flowed around the unknown energy. He concentrated intently on casting his spell, sweat gradually beading on his forehead, his eyes revealing a focused and resolute expression.

However, the results of the decomposition surprised him somewhat; he only obtained trace amounts of magical and temporal elements, along with some unknown power. This mysterious, unknown power was like a mystery hidden in the mist, impossible to fathom. The Elf Dragon King (in human form) couldn't help but ponder to himself, "Could this be the little thing the black mage was talking about researching? How interesting, I'd like to study it myself."

So, the Elemental Dragon King (in human form) used energy manipulation to try and envelop the unknown energy. His hands emitted a soft light, gently touching the energy as if engaging in a mysterious dialogue. He bound it with powerful energy, like creating a transparent cage to imprison it. Then, he used several Elemental spells to reinforce and defend the energy. Magical light flickered around, forming a sturdy shield to ensure no excess magic leaked out.

Finally, the Elf Dragon King (in human form) carefully placed it in an exquisite bottle. This bottle emitted a mysterious light, and the runes on its surface shimmered with an eerie brilliance, as if guarding the secret of the unknown energy within. Through the resonance between the runes and the unknown energy, the connection between this energy and those products of dark magic was completely severed.

Sure enough, after the Underworld Emperor destroyed the newly appeared black magic artifacts again, no new batches appeared. Everything seemed to have returned to a temporary calm. However, during this time, the Elf Dragon King (in human form) was filled with curiosity about this mysterious and unknown energy, wondering what secrets it held. Every time he looked at the unknown energy in the bottle, the flame of curiosity in his heart burned even brighter.

Goddess Avalin spoke slowly, her voice echoing in the tranquil main hall, as if coming from a distant valley, carrying a hint of barely perceptible doubt and worry: "Underworld Emperor, although this instance has ended, many questions remain unanswered, especially that mysterious energy, which will likely bring many variables in the future. We should gather our wisdom as soon as possible and discuss the follow-up matters together to prevent any unforeseen problems."

However, the Underworld Emperor seemed to ignore the words of the goddess Avalin. He stood there quietly, his back to the crowd, his figure appearing somewhat lonely and forlorn in the dim light. The light around him gradually dimmed, as if merging with the surrounding air, as if silently bidding farewell to the world. Before disappearing, he left Wang Xiaoyi with a sentence, "Come to the Underworld after you've finished your business." In an instant when no one noticed, he flashed away without saying goodbye, disappearing from the main hall like a black streak of light, leaving only silence and the confusion of the crowd.

Goddess Avalin frowned slightly. She had intended to stop the Underworld Emperor from leaving and continue discussing the unresolved matters with him. She knew that if these doubts weren't resolved, they could lead to even greater crises in the future. However, when she considered the Underworld Emperor's strength and the gap between them, her anger gradually subsided. She knew that with her current strength, trying to contend with the Underworld Emperor was like throwing an egg against a rock; in the end, she might not only fail to stop him but also put herself in danger. She could only lower her head helplessly, hoping that the Underworld Emperor could find a solution in the Underworld. At this moment, a complex atmosphere filled the main hall. Everyone's face bore their own thoughts, as if they were all contemplating the challenges they might face in the future.
