Gao Liang said, "Your father has treated you well!" But upon seeing that Gao Liang's injuries had not yet healed, Xiao Longnü immediately exclaimed, "Hurry! Let's practice some healing exercises to expel the toxins!" Sitting together on an open clearing, Xiao Longnü pressed her palms firmly against the back of Gao Liang, continuously exerting her strength. Fine beads of sweat began to form on Gao Liang's forehead. "It's not good! Gao Liang's back is growing colder!" Xiao Longnü noticed the coldness intensifying—indeed, the sea tree's toxic spines had penetrated deeply, reaching even into the very depths of Gao Liang's body. She then placed a particularly precious dragon pearl, left by her father, into Gao Liang's mouth. Instantly, Gao Liang felt a refreshing sensation throughout his body. This royal dragon pearl, one of the great treasures of the Eastern Sea Dragon Palace, was renowned for its ability to purify and strengthen the body. With this pearl, Gao Liang now had the strength to resist the sea tree's toxins. Under Xiao Longnü's healing care, Gao Liang gradually recovered. For the first time visiting "What is this?" Xiao Longnu exclaimed in surprise. Gao Liang smiled and said, "This is a secret manual from the Dragon Palace!" When Xiao Longnu looked closer, she saw the title 'Secret of the Dragon Palace!' written in ancient characters—she didn't recognize them, but Gao Liang did. He had studied ancient scripts at Kyoto University, and thus was familiar with these characters. Quickly opening the manual, Gao Liang found that it detailed exactly how to train and advance within the Dragon Palace. Various training techniques and insights were thoroughly recorded in the book, and he immediately began practicing one of the movements described. Xiao Longnu still didn't recognize the ancient characters, only gazing at them with wide eyes. "Xiao Longnu! Come over here and help me!" Gao Liang called out, and she promptly arrived. Following Gao Liang's request, Xiao Longnu threw a flying flower needle toward him, but she said, "Be careful!" "Otherwise, if we're truly hit, it'll be dangerous!" Gao Liang said. "No problem! I can easily dodge!" Just as he spoke, Xiao Longnü's flying flower needles shot directly toward Gao Liang's face. With quick reflexes and nimble movements, Gao Liang deftly avoided them, and the needle flew swiftly toward a large nearby rock. "Crack!" The rock was struck, creating a small hole. "That's impressive! Truly impressive! You actually managed to dodge!" Xiao Longnü praised. Gao Liang smiled and said, "Not much, really! I don't consider myself particularly skilled. In fact, this secret technique is quite excellent—my very dodge just now was precisely guided by it!" Xiao Longnü glanced at the secret technique but couldn't understand it. Nevertheless, she said to Gao Liang, "I believe in you! You'll succeed!" Gao Liang replied, "We must practice diligently. There's a style of martial art known as the Yin-Yang Male-Female Sword. We need to work in harmony. Once we master the Yin-Yang Sword, we'll surely be able to handle that troublesome black dragon!" "Little Longnü clapped her hands excitedly: 'Great! Great!' 'Let's practice right away! We must master it—quickly, master it!' After speaking, Gao Liang demonstrated a move, and Little Longnü followed suit, replicating each action. Soon, both Gao Liang and Little Longnü drew two swords each from the broken stones beside them, holding one sword each. 'Shushushushushushu!' They swiftly produced a cascade of sword patterns, each blade angled diagonally, and began practicing according to the secret method. Practicing swordsmanship underwater, indeed, was no easy task. Though Gao Liang was skilled on land, mastering sword techniques in deep water required adapting to the buoyancy of the sea or the pressure of the surrounding water. Following the secret manual for the Yin-Yang Sword style, through mutual coordination and focused training, Gao Liang and Little Longnü soon built up their strength and, together, launched a powerful joint attack at a distant stone stele standing about three zhang high. 'Crack! Crack! Crack!' "Three powerful crashes as the Yin and Yang swords struck the great stone stele. Hit by the dual streams of sword energy, the massive stele was severed right down the middle, and Gao Liang and Xiao Longnü were thrown horizontally from within. The towering stele, over three zhang high, collapsed completely!" "Gao Liang and Xiao Longnü! We've succeeded! We've finally mastered the Yin-Yang Twin Swords!" Their voices echoed through the secluded paradise of the Eastern Sea Dragon Palace. Secure all key passages—pay close attention to any suspicious individuals infiltrating; report immediately, or take action! "Yes, Your Majesty!" The shrimp and crab troops promptly responded and set off to secure all vital entry points within the Dragon Palace. Black Dragon now occupies the Eastern Sea Dragon King's palace, even the entire imperial court. The Eastern Sea Dragon King's grandchildren and granddaughters have all been detained and held together. Among them, the young, beautiful female dragons are confined in a dedicated pavilion. That day, Black Dragon had consumed a great deal of wine and staggered toward the pavilion where the young ladies were held. "Little beauties! Hehe! As long as you pledge yourselves to me, Black Dragon, and become my consorts, I promise you will never be treated unfairly!" Speaking with the wine still in his voice, Black Dragon's breath was so strong that the young ladies had to cover their noses, finding it most unpleasant. Yet, he reached out with his salted pork hands, gently caressing the soft chests of several of the young ladies. "No! No!" the young ladies cried out in alarm. Huddled together, the several women clutched each other tightly, staring at one another with expressions of fear. "As long as you all follow me and become my women, I will treat you well!" said He Long, a man renowned for his passion and prowess in the arts of seduction. With a sulky expression, he turned to the several young beauties. The young women were deeply afraid, trembling and pleading, "He Long! Please don't come near! Don't come near!" Yet He Long insisted, "I insist on coming! I insist on coming! What can you do?" "If you truly come, then I shall die right before you!" said one of the young women, drawing a hairpin from her head and plunging it into her throat. However, another sister stepped forward and said to her, "Little sister! Don't be so foolish! To die for He Long is truly not worth it! Not worth it at all!" "Then what should we do?" asked the young woman, her eyes brimming with tears and her heart full of anguish. "Sisters! We must absolutely not allow He Long to succeed. But we will stand united!" That sister was brave and wise. She shared her thoughts with several of her sisters, who were immediately inspired and nodded enthusiastically. At that moment, the three sisters broke from their usual demeanor—especially the younger one, who now performed seductive gestures toward the black dragon, exclaiming, "King! Come here! Come quickly!" Her voice was sweet and inviting, so charming that even the black dragon felt stirred to his core. Wow! What a turn! Truly unexpected—these dragon princesses had finally awakened. Watching the three beautiful dragon princesses, the black dragon felt delighted, daydreaming so much that he didn’t even realize droplets of saliva were dripping from his mouth to the ground. He extended his rather clumsy hand, reaching toward the young, attractive sister’s chest, but she swiftly stepped back, placing a chair in front of him and saying, "King! Please sit! Sit down, please!" The black dragon happily settled into the chair with a contented sigh. Oh my! The dragon was so touched—he even started crying. To his surprise, there was a slender silver needle resting on the chair, and the black dragon sat down precisely upon it, the entire needle piercing deep into his spine, causing him to howl with pain as if being slaughtered. "You! You dare play tricks on me? Very well—I shall make you pay!" As the dragon was about to rage, the elder sister stepped forward and, in front of the dragon, removed one of her garments, revealing her crimson bodice. The dragon, ever fond of beauty, was stunned into silence, completely forgetting his earlier anger. "Your Majesty! We truly didn't mean to—there was a silver needle on the chair, and we had no idea what had happened!" The little sister pouted, her face full of embarrassment, and the dragon, seeing her expression, could hardly help but feel the same. Thus, his anger softened by a third. Ever since he had seen the three young, beautiful maidens, the dragon had been restless, his interest piqued. He now rushed eagerly toward them, and the young ladies immediately cried out in alarm, as if startled birds.
