The male protagonist of the book is poisonous

Passing through the wall of light emanating a mysterious power, a fresh and chilling breath washed over us like a spirit. We officially entered the mountain's interior, and a vast cave appeared before us. Crystals of various colors were inlaid on the cave's walls like stars. These crystals shimmered with a dazzling array of light, illuminating the entire cavern. It looked like an underground palace meticulously carved by the forces of nature.

We slowly made our way through the cave's winding passages, the ground beneath our feet slippery and slippery, requiring every step to be taken with extreme caution. The ground seemed composed of a unique mineral, reflecting a faint halo of light under the light of the crystals. As we walked, the sound of gurgling water drifted in, echoing through the silent cave like a beautiful melody, its notes dancing and weaving through the air, stirring our hearts.

"There should be a water source nearby, maybe it's a pure spring." My eyes were full of anticipation, and there was a hint of uncontrollable excitement in my voice.

However, as we approached the sound of running water, danger loomed like a shadow lurking in the darkness. A swarm of crystal scorpions slowly emerged from the corner of the cave. Their bodies, composed of transparent crystal, gleamed with a chilling coldness against the surrounding crystal light. Their tails arched high, their sharp stingers like deadly daggers, ready to strike at any moment.

"Everyone, be careful. These crystal scorpions are not easy to deal with." Brother Ling Xiao warned seriously, his eyes fixed on the gradually approaching group of crystal scorpions.

Without hesitation, I gripped my divine sword and charged at the swarm of crystal scorpions. The divine sword collided with the crystal scorpions' bodies, making a crisp sound, like the sound of glass clashing against each other, especially piercing in the silent cave. The crystal scorpions quickly closed in on me, their massive, sharp pincers slamming down on me. Each pinch sent a gust of wind, like the roar of death.

Brother Lingxiao joined the fray without hesitation. His attacks were like the swift movements of a snake, nimble and versatile, deftly avoiding the crystal scorpion's counterattacks. His swift movements, his weapon wielding silver streaks of light through the air, each one precisely targeting the crystal scorpion's weak spot. The elves, on the side, cast supporting spells, chanting incoherently as they waved their wands, emitting soft light. That light, like a trickle of water, slowly flowed through our bodies, enhancing our strength and speed, making us even more agile in our battle against the crystal scorpion, as if infused with a mysterious vitality.

The Guardian of Light stood behind us, intently casting a shield of light. The shield radiated a dazzling white light, like a giant protective shield, tightly guarding our rear and preventing any Crystal Scorpions from attacking from behind.

However, the crystal scorpions were numerous, pouring in like a tide, and we gradually became mired in a fierce battle. One of them took advantage of my moment of distraction and stabbed my leg with its venomous stinger at breakneck speed. I couldn't dodge, and the stinger lacerated me. Instantly, a numbness spread through my leg, as if countless tiny electric currents were running through my body. My leg began to feel heavy and weak.

"I'm poisoned, but don't worry about me, let's deal with these crystal scorpions first." I gritted my teeth and said while enduring the pain, beads of sweat already oozing out of my forehead.

Seeing this, the elves hurriedly cast their detoxification spells. A green light emanated from the tips of their magic wands, wrapping around me like a green vine. The light slowly seeped into my body, fiercely battling the toxins within. Wherever the green light touched, the numbness seemed to ease slightly, but the toxins remained stubbornly strong, fighting a fierce battle within my body.

While the elves were detoxifying me, Brother Lingxiao and the Guardian of Light intensified their attacks. Brother Lingxiao unleashed a fierce sword technique, his figure like a whirlwind, darting through the swarm of crystal scorpions at high speed. Each thrust of his sword was powerful and precisely angled, striking the crystal scorpions' vital points. The Guardian of Light concentrated the power of light in his hands, transforming them into two dazzling sources of light. Then, he thrust his hands forward, sending a powerful shockwave of light caressing the crystal scorpions like a surging ocean wave. Wherever it struck, the crystal scorpions were toppled, some flung back and forth, slamming into the cave walls.

Under their combined attack, the crystal scorpions began to retreat. Their attacks were no longer as ferocious as before, and their formation became disorganized. Finally, the remaining crystal scorpions, seeing the situation was dire, fled back into the depths of the cave, their fleeing figures quickly disappearing into the darkness.

"How do you feel?" Brother Ling Xiao asked me with concern, his eyes full of worry.

"Much better, thanks to the elves' detoxification magic." I wiped the sweat from my forehead and looked at the elves with gratitude.

We rested briefly, then continued our steady progress toward the sound of flowing water. Soon, a massive spring appeared before us. Surrounding it was a ring of white stones, which shone with a soft, white glow, as if guarding the spring. The water was crystal clear, like a mirror, revealing every pebble. Water continuously gushed from the spring, forming a small pool at the bottom. The water in the pool, like flowing crystal, shone with a captivating luster.

"Is this the Fountain of Purity?" The Guardian of Light frowned and asked in confusion.

I carefully took out the elemental crystal, eroded by darkness, and slowly walked toward the spring. As the crystal approached the water, ripples suddenly formed, spreading outward like tiny concentric circles. It seemed the water had some special reaction to the crystal, a reaction that both excited and unnerved us.

Just as we were about to place the elemental crystal into the spring, a dark figure emerged from the depths like a ghost. It was a pitch-black water monster, massive yet agile, its massive form not appearing at all clumsy in the cave. Its two red eyes, like blazing flames, glared fiercely at us, their gaze revealing a deep hostility.

"It's not that easy to purify the crystal!" The water monster let out a low roar, and the roar echoed in the cave, as if it was a roar from hell, making the air in the cave seem to become cold.

The monster opened its maw and spewed a stream of black water at me. Like a giant black python, it lunged at me with its fangs and claws bared. I quickly dodged to the side as the black water struck the nearby wall, instantly corroding a large crater. Black smoke billowed from the edge of the crater, emitting a pungent odor, as if infested with the breath of a demon.

"It looks like we have to fight again." I sighed helplessly, but my eyes were full of determination.

We prepare for battle once again, our sacred swords, magical powers, and the forces of light united once more. This time, we are determined to win, our goal being to defeat the water monster that guards the Pure Spring, successfully purify the elemental crystal, and save the world from the threat of darkness.
