The male protagonist of the book is poisonous

The black-robed figure's threatening voice still echoed through the hall, like coarse sandpaper, scraping every inch of air. His malicious words, like the irritating buzzing of flies, stubbornly lingered in the air. But now, our attention was drawn even more to the enchantingly glowing treasure box before us, much like a ship sailing in the darkness being drawn to a distant lighthouse.

I maintained my sword pointed at the black-robed figure, but my eyes involuntarily glanced toward the treasure box. The treasure box resembled a mysterious and brilliant star, radiating a captivating, multicolored light from the depths of the universe. Having just weathered the vortex of darkness, this light grew even brighter and more dazzling, as if infused with new vitality. Countless spirits seemed to joyfully flit within the light, leaping and playing, each movement imbued with a vibrant beauty. It was as if a mysterious stream of energy gurgled through it, a living fluid that radiated a subtle warmth. Each ray of light felt like a living tentacle, gently caressing the surrounding air and exuding a powerful yet reassuring aura, like a mother's embrace, offering endless comfort.

Luo Chen slowly approached the treasure box, his steps as light as a cat's, each one cautious, as if the ground beneath his feet were a minefield rife with traps. His eyes brimmed with curiosity, like a child about to explore a mysterious treasure. A fierce desire for the unknown burned within them, a fiery fire. The little boy followed closely behind him, his tiny hands clutching the hem of Luo Chen's shirt tightly, as if grasping at a last straw. His eyes were filled with anticipation, as if the treasure box held the most wondrous treasure in the world. That anticipation, like the breaking light of dawn, filled him with hope. As Luo Chen approached the treasure box, he could clearly sense a powerful yet gentle force emanating continuously from it. This force, like a spring breeze, gently caressed his face, bringing a touch of coolness and comfort, a stark contrast to the cold, sinister power emanating from the black-robed man, like the bitter cold of winter. The black-robed man's power was like an ice knife, biting and filled with malice, while the power of the treasure box was like a gentle spring breeze, warm and full of life.

Luo Chen stretched out his hand, its hand trembling slightly in the air, like a leaf shivering in the autumn wind. He wanted to touch the treasure box, but just as he was about to do so, he hesitated, as if held back by an invisible force. His mind was torn between curiosity and caution, like two little figures engaged in a fierce battle within his mind. On one hand, the curious little figure cried out, eager to uncover the mystery of the treasure box immediately; on the other, the cautious little figure held him tightly, warning him of the unknown dangers that might lurk within. He turned to look at me, his eyes filled with questioning and expectation, as if seeking a final redemption, as if seeking my approval. I nodded slightly. After all, we had overcome countless hardships to reach this point. Now was the time to explore the secrets of the treasure. We couldn't retreat out of fear. Like an adventurer climbing a mountain, we'd almost reached the summit, but couldn't let a last glimmer of fear stop us from seeing the magnificent view.

Luo Chen's hand gently rested on the treasure box, and instantly, a soft light spread from the point where the treasure box and his hand touched. The light, like the first rays of morning sun, gently and swiftly enveloped him. A look of surprise first crossed his face, his eyes slightly widening like two suddenly lit stars, and his mouth unconsciously parted, forming a small "O" shape. But soon, the surprise faded into a sense of ecstasy, as if he were in a wonderful dream. His expression softened, as if overwhelmed by a tide of happiness, and his eyes held a hazy hue, as if he had witnessed the most beautiful scene in the world.

The little boy nervously asked, "Brother, are you okay?" His voice trembled with worry, like a gently plucked string. His hands unconsciously clenched tighter, his knuckles turning slightly white from the pressure, an outward manifestation of his worry.

Luo Chen didn't answer immediately. The light seemed to carry him into a distant world, a trance-like state. His consciousness seemed to have traveled through a tunnel of time and space, entering a world constructed by the secrets of the treasure box. After a moment, he slowly said, "I saw some images. The secret of this treasure box seems to be related to the origin of this castle." His voice had a dreamlike quality, as if it floated from a distant land, or emanated from underwater, vague yet full of mystery.

I asked curiously, "What picture? Tell us quickly." My eyes were fixed on Luo Chen, and my eyes were full of desire for the secret of the treasure box. It was a greed for unknown knowledge, like a hungry person seeing food.

Luo Chen began to describe the scene he saw: "I saw that a long time ago, this castle was built by a group of kind magicians. Those magicians were dressed in gorgeous robes, which seemed to be made of the finest silk, embroidered with mysterious runes and gorgeous patterns. In their hands, they held shining wands, and the tops of the wands were inlaid with various precious gems. The gems reflected colorful light under the sunlight. They gathered together with solemn and sacred expressions on their faces, as if they were performing a great sacrifice. They used their powerful magical powers to gather countless positive energies. These positive energies were like bright starlight, converging from all directions to a central point. Each starlight was like a smart silk thread, floating in the air. It drew a graceful arc. Then, it was sealed within the treasure box. As the treasure box absorbed this energy, it was like a hungry vessel, constantly absorbing it. They did this to protect this land and its people. This land was so beautiful then. Amidst verdant mountains and clear waters, clear streams gurgled through the valleys, making a crisp sound like a beautiful symphony composed by nature. The fields were filled with golden wheat, and in the gentle breeze, the waves rolled like a golden ocean. People lived happy and fulfilling lives. Children laughed and played in the fields, their laughter as clear as silver bells, echoing in the air. Elderly people basked peacefully under the trees, their faces filled with contented smiles, like the warm sun on a winter day.

He paused, as if gathering his thoughts, and then continued, "But later, an evil force coveted this positive energy. That evil force, like a shadow in the darkness, spread silently. Their members wore black robes, which seemed to be made of the fabric of the night, and exuded a gloomy aura. Their eyes flashed with greed and evil, and those eyes were like hungry wolves seeing their prey, full of blood and cruelty. They launched a brutal war, and the flames of war instantly swept the entire castle. The flames shot up into the sky, dyeing the sky blood red, and thick smoke filled the entire sky, like a huge black curtain. Although the magicians fought hard, casting all kinds of powerful spells, the magic light illuminated the entire night sky, and the light was like a dazzling firework, blooming in various beautiful patterns in the night sky. However, the power of evil was too strong. They continued to surge in like a tide, wave after wave, seemingly endless. Eventually, some of the evil forces infiltrated the castle. These evil forces were like viruses, slowly eroding every corner of the castle. They crawled along the walls like black vines, devouring the vitality of the castle bit by bit. This is why the castle is now full of danger.

I said thoughtfully: "So what should we do now? Should we take the treasure box away, or find a way to seal the positive energy somewhere in the castle again?" My brows furrowed slightly, and I was weighing different options in my mind, like a chess player thinking about his next move.

Luo Chen shook his head. "I'm not sure, but I feel like this treasure box shouldn't be taken away so easily. It's become one with the castle, and if it's taken away forcibly, it might disrupt the balance here. Just like a sophisticated mechanical device, every part has its function. The treasure box is the core part of this castle. If it's forcibly removed, the entire castle might fall into chaos. The treasure box is like the heart of the castle. Once it's taken away, the castle will lose its vitality, just like a person who loses their heart will cease to exist."

As we were discussing this, the bound black-robed figures began to stir again. One of them, like an enraged beast, shouted, "You fools, you have no idea what you're doing. If you don't hand the treasure box over to our master, this castle will suffer an even greater disaster." His voice was filled with anger and anxiety, like a volcano about to erupt, and his eyes gleamed with a mad glint, a blazing flame filled with desperate madness.

I frowned and said to the man in black, "Your master only wants to use the power in the treasure box to do evil. How can we hand over the treasure box to him? Your master is like a greedy thief who only wants to take things that do not belong to him for himself, and then use it to create destruction and chaos. He is like a demon in the dark, trying to drag the world into endless darkness." My words were full of contempt for the man in black and his master, and that contempt was like a cold wind, blowing towards the man in black.

The man in black robe sneered: "Do you think you can control the power of the treasure box? You don't understand the true purpose of this power at all." There was a sarcastic expression on his face, and the corners of his mouth rose slightly, forming a contemptuous arc, as if he knew some secrets that we didn't know. That secret was like a treasure hidden in the deep sea, which only he knew.

Luo Chen walked up to the man in black robe, his eyes filled with determination and a desire to explore, and said, "Then tell me, what is the real purpose of this power?" He tried to get more information about the treasure box from the man in black robe. His eyes were like two sharp swords, piercing straight at the man in black robe.

The black-robed man shut up and stopped talking. He pursed his lips tightly, as if guarding a profound secret, unwilling to reveal a single word. His lips were pressed into a line, like a solid city gate, determined not to let any information leak out.

At this moment, the treasure box's light shifted again. Like a stirred lake, it rippled with strange waves, each a mysterious symbol. Strange symbols appeared within the light, resembling ancient texts or mysterious totems. Their complex lines and shapes made each symbol a living entity, imbued with boundless mystical power. They floated slowly through the air, like a flock of nimble butterflies dancing, their flight paths a carefully choreographed dance, graceful yet mysterious. Then, they slowly soared toward the castle walls. We watched in amazement, our eyes following the movement of the symbols, filled with confusion, wondering what the treasure box was supposed to do. That doubt, like a thick fog, enveloped us.

The little boy suddenly shouted, "Look, those symbols are embedded in the wall!" His voice rose several tones with excitement, and his little hand excitedly pointed in the direction of the wall, his fingers trembling slightly.

As the symbols embedded themselves into the walls, the castle began to tremble slightly. The tremors were like mild earthquakes, the ground beneath our feet swaying in waves, as if shaken by an invisible hand. Fearing danger, we quickly prepared for defense. I gripped my sword tightly, my arm muscles bulging with the effort, and I crouched slightly, like a cheetah about to pounce on its prey, ready for any possible attack. Luo Chen also raised his wand, silently chanting a defensive spell. Magical energy began to gather around him, shimmering like a swarm of fireflies. The little boy hid behind us, his hands clutching our clothes tightly, his body pressed against our backs, as if this would provide the greatest protection.

But after the trembling subsided, we noticed that some of the castle's dark corners began to light up. Those areas, once shrouded in darkness, gradually became brighter, like clouds pierced by sunlight. The evil aura hidden in the darkness seemed to gradually dissipate, like morning mist slowly dissipating under the sunlight. Those dark corners seemed to be infused with vitality, and the once decayed atmosphere was replaced by fresh air.

I said in surprise, "Is the treasure box purifying the castle?" My eyes were shining with excitement and my heart was full of hope. That hope was like a lit lighthouse, shining brightly in the darkness.

Luo Chen nodded. "It's very possible. The positive energy in the treasure box may be repairing the damaged balance of the castle. Just like a doctor healing a sick patient, the treasure box is using its power to eliminate the evil germs in the castle. The treasure box is like a miracle doctor. Its positive energy is the best medicine, healing the castle's wounds bit by bit."

As the treasure box continuously released its energy, the evil within the castle dwindled. The dark creatures, brought by the black-robed men, which had previously lurked in dark corners, began to flee. Like rats without shelter, they scurried about the castle in panic. Some of the dark creatures, fleeing, collided directly with the walls, emitting a dull thud that echoed through the castle like a death knell. Their forms varied, some resembling giant spiders, others twisted humanoids, all frantically searching for a way out.

The black-robed men watched this scene with horror on their faces. They knew that once the castle's evil was completely eliminated, their plan would be utterly defeated. Their eyes were filled with despair, like drowning men seeing their last glimmer of hope shattered. Their bodies began to tremble uncontrollably, their trembling like leaves falling in the autumn wind, uncontrollable.

We stood beside the treasure box, watching the castle slowly come back to life. Vibrant vines sprouted from the walls once eroded by darkness, their leaves sprouting tender green, like the castle's renewed vitality. We were filled with relief. Although we didn't know what would happen next, at least for now, we had successfully prevented a greater disaster. We felt like heroes protecting the castle, witnessing the rebirth of this ancient building. It felt like discovering an oasis in the desert, filled with surprise and a sense of accomplishment.
