The Dragon Palace was built on a mountaintop on the seabed, with aquatic plants and corals. A pearl was inlaid on the top of the Dragon Palace, which shone with endless brilliance. The colorful light was flowing, and the light could be seen swimming and condensing like water under the water. A formation restriction enveloped the Dragon Palace, and the seawater was isolated. Schools of fish of all sizes swam around the barrier. There were also natural stone buildings outside, which looked like houses and caves, covered with aquatic plants and corals. Many mermaids could be seen coming in and out, and they usually lived outside. It was said that thousands of years ago, this place was the nest of the real dragon, sitting on the sea and ruling all the aquatic creatures. How powerful and prosperous it was. Now even the mountaintops have collapsed, leaving only a dozen large and small palaces, and this is the scene after the Mermaid Kingdom was repaired and rebuilt later. Even so, in the eyes of Qingyang and Zhu Liu, the palace group blooming with thousands of feet of light on the seabed was like a miracle. The three followed the thousands of mermaids and the surging water of magic through the sea, feeling the pure sea water like the ancient sea brushing against their faces and hair, and looking at the light on the seabed in the distance with their eyes open. A large number of mermaids were wandering in front of the Dragon Palace, and even the sea water was filled with a bloody smell. It seemed that there had been a great battle in the Dragon Palace before. Many dead mermaids could be seen floating in the sea, and then the mermaids collected the bodies of the dead mermaids into huge shells as wide as a person. In front of the palace building lay a black two-headed vicious snake that was much smaller than the previous evil dragon, but that was only compared to the evil dragon. This snake was more than 30 meters long and looked like a meat mountain lying in front of the Dragon Palace. However, at this moment, the black two-headed vicious snake had been cut into two pieces and turned into a corpse. The two fierce and ferocious heads looked into the distance with their eyes wide open. And around, you can see groups of large fish bodies with human faces and long tails floating in the water. Most of those fish with human faces have their bellies facing outwards, their skin and flesh torn and their intestines turned outwards, as if they had exploded from their bodies. Without thinking too much, you know that the evil dragon must have had a fierce battle with the mermaid country here. I don’t know what the evil dragon wants to steal. The mighty army of mermaids dispersed, and Fang Xiu and the other two followed the mermaid Dragon Palace Guards to sneak into the Dragon Palace. The three of them just passed through the formation barrier and broke into it. It seems that this formation barrier is mainly to block the sea water and has the function of early warning, and it does not really have defensive power. The three of them broke into the formation restriction, stood still, waved their sleeves, and saw the water vapor on their bodies vibrate and dissipate, and at the same time looked at the Dragon Palace in front of them. Qingyang Sanren was absent-minded for a long time and then sighed: "I never thought that a mortal like me, Zhang San, would be invited to visit the Dragon Palace one day!" Zhu Liu also said with a sigh: "Traveling in the mountains and seas, breaking into the demon city, fighting evil dragons, entering the Dragon Palace! Now we can't be considered ordinary people!" "Those gods in ancient myths and stories! They are just like us!" Walking forward along the white jade floor square, passing through the towering Dragon Palace gate, approaching, the pearl light on the top of the Dragon Palace made it difficult for people to open their eyes. "Dear guests, please! The king is waiting in the hall!" More than a dozen mermaid maids who had been waiting on the side welcomed the three people into the room. Unlike the mermaids outside who were covered by scales, they wore a thin and soft shirt that looked like seamless heavenly clothes. This was a dress made of dragon silk unique to the mermaids. The graceful figure inside the thin shirt was vaguely visible. To be honest, it was more tempting to wear it than not to wear it. Fist-sized pearls were placed on the lotus platform, illuminating the long corridors, or inlaid on the top, illuminating the bright rooms. Walking along the gorgeous palaces, gold and jade treasures were everywhere. The richness of the sea was indeed no less than that of the earth, and the luxury was unimaginable. Or it could be said that the mermaids who inherited the Dragon Palace had obtained resources that were so rich that it was jaw-dropping. The three of them passed through the unique style of the underwater rockery garden and finally arrived at the main hall. The main hall was tens of meters high and looked like an ancient temple. The thick pillars were carved with golden painted beasts. On both sides, rows of strong male mermaids stood with weapons in their hands, looking mighty and ferocious. The three of them walked into the main hall, where a faint scent of ambergris was burning. They finally saw the legendary female monarch of the mermaid country. They only saw a cold and frosty beauty sitting on the throne, her translucent sleeveless gauze skirt dragging on the ground, her white arms resting one hand on the throne and the other on her abdomen, the whiteness of her chest could not be covered at all, and it contrasted with the gem necklace that penetrated into it. Her delicate wrists and ankles were all wearing golden bracelets, and she sat on the throne with her bare feet crossed, looking down at the three of them. She seemed to be not good at speaking, and everything was conveyed by the waiter beside her. The one who spoke was the mermaid girl who had met them before. At this moment, the three of them knew that her name was Hong Xiao, and she was standing behind the female monarch of the mermaid country in a red maid's dress. The three of them were looking at the female monarch of the mermaid country, and the female monarch was also looking at the three of them at the same time. Her beautiful eyes were as warm as the sea, and had the violent indifference of the sea, which made people feel unpredictable. According to the feelings of the three of them, she really had a hint of the demeanor of an emperor, but at this moment, it appeared on a woman. Fang Xiu stepped forward and handed over a letter written in tortoise shell seal script: “Fengdu! Qingyang! Zhurong! The three of you are carrying a letter from the Lord of Chiyan of Yumin Kingdom, requesting to see the Queen of Jiaoren Kingdom!” Hongxiao glanced at the Queen of Jiaoren Kingdom and nodded: “Hand it over!” After the Queen of Jiaoren Kingdom finished reading, she whispered a few words to the mermaid girl Hongxiao beside her. Hongxiao immediately said: “The Jiaoren Kingdom has felt the sincerity of the Lord of Chiyan, and will send an envoy to visit the Yumin Kingdom in a few days to discuss the issue of opening border markets between the two sides.” At this time Fang Xiu said again: “In addition, the three of us have another request! It has nothing to do with the state affairs of the Yumin Kingdom and the Mermaid Kingdom, but our private affairs!” Hongxiao said: “Speak!” “The three of us are from the human world, and mistakenly entered the world of mountains and seas. We heard that the Mermaid Kingdom knows how to return to the human world, so we came here specially!” This time, it was not Hong Xiao who spoke, but the Queen of the Mermaid Country who spoke for the first time. Her voice was as cold and majestic as her face. "According to rumors from ancient times, at the end of the mountains and seas! In the depths of the Nether Sea, in the endless void, there is a fairy island called Nether City!" "Nether City can lead to the Three Realms and Six Paths, the Cave Heaven and the Land of Reincarnation, but the whereabouts of Nether City are uncertain, wandering outside the mountains and seas, and ordinary people cannot find it!" "And to reach Nether City, you must cross the Nether Sea. Ordinary people will only die if they go in." Qingyang Sanren seemed a little anxious: "Excuse me, Queen, is there any way to find Nether City?" The Queen of the Mermaid Country pondered for a long time: "Forget it! You help me expel the evil dragon Qingli, and we will cancel it out!" The Queen of the Mermaid Country waved her hand, and not long after, she saw the merman maid next to her holding a strange object. It was a bronze lamp, with a heavy long pole and copper lamp, on which were carved several hideous evil ghosts. Two ancient seal characters could be vaguely seen on the tube lamp - Youdu! "Hold this lamp, light it with magic power to keep it immortal, and you can cross the sea of the underworld and guide you to Youdu!" "But it's just a rumor. After all, everything in ancient times has disappeared. In this era, whether Youdu still exists or not, whether the three of you can reach Youdu and return to your hometown depends on your fate!" "I have important things to do and can't stay for long! The female monarch of the mermaid country stood up after she finished speaking, her long gauze dragged on the white jade floor, and she walked away with her long legs, accompanied by the crisp sound of chimes. A dozen waiters followed her at the same time. The groups of classical and beautiful beauties made Qingyang and Zhu Liu unable to take their eyes away. Hong Xiao received the three of them on behalf of the female monarch of the mermaid country, standing on a high place and said: "It's over! Please leave as soon as possible! Our country of mermaids has encountered a great change and is temporarily unable to entertain guests. Please forgive us!" "Your boat has been salvaged! Hong Xiao will take you there later!"
