“Hey, there seems to be a sign here. Lin Xuan, do you recognize the language of the Sea Race?” Tian yucai noticed a mural on the wall, which seemed to depict the imperial city in detail. Lin Xuan’s eyes lit up when he saw the mural. “It really is.” “We are now in… The Royal Palace Avenue?” “Other than that, there’s also the sea serpent palace, which stores the huge documents of the sea race, the 18 servant races, and the 45th World.” “The Sea Shark Palace stores the best weapons and equipment of the sea race.” “The sea lion palace, the Sleeping Palace of the Sea King.” “The Sea Consort Palace, the Sleeping Palace of the Sea King’s 18 concubines.” Tian Yucai’s eyes lit up when she heard that. “Let’s go to the sea serpent palace first. The documents are stored there, so there must be mechanical drawings!” Lin Xuan said, “That’s what I was thinking too. Let’s Go!” The two of them headed straight for the sea snake hall. After running for more than an hour, they finally arrived at the front door of the sea snake hall. Then, Tian Yucai was stunned. This was because this thick and heavy stone door that was a few hundred meters tall was actually tightly shut! The stone door was extremely smooth. She could not even see the crack in the middle of the stone door. Those who did not know would have thought that this was a door made of an entire boulder! Tian yucai looked aggrieved. “What should we do?” She was like a hungry child now. There was a feast inside the glass, but the glass was ridiculously thick and could not be opened at all. “Why aren’t you discouraged at all?”Tian yucai glanced at Lin Xuan and found that he was still full of confidence, as if he had a way to open the gate. Then she saw Lin Xuan take out a mirror directly from the storage compartment. It was a bronze mirror with seven heads carved on the back. “You… you still want to look at the mirror at this time? !” Tian yucai was a little confused. “Look carefully,”Lin Xuan chuckled. “Since I’m here, how could I come back empty-handed?” Then, he walked to the door and pressed the seven-headed sea snake mirror gently on it. In the next moment, the thick and heavy door actually emitted the sound of turning. The gears clenched and the mechanism turned. A small crack actually appeared on the door. Tian yucai’s mouth was wide open in shock. Then, the door opened even wider. In less than half a minute, it was completely opened. A huge palace quickly appeared in front of them. A dusty, ancient aura blew over. Tian yucai looked around. There were a lot of documents on each bookshelf! Even after years of wear and tear, these documents were not damaged at all! Tian Yucai’s eyes lit up. She rushed up on the spot. Then, she awkwardly realized that she couldn’t see the language of the sea tribes at all. “Help me take a look. I just want to see the mechanical-related documents.” Tian yucai coughed lightly and requested. Lin Xuan nodded. He walked around the bookshelf and finally stopped in front of a huge bookshelf. “This bookshelf is full of mechanical-related documents, but it would be a waste of time for me to translate them word by word for you.” “How about this, you learn the language of the sea tribe first.” As Lin Xuan spoke, he took out the sea tribe translation dictionary from the storage compartment. Tian yucai flipped through it and her eyes lit up because she had also seen the progress bar in front of her. “So it’s all because of this thing that you can understand the sea tribe’s language! You’re so lucky.”Tian yucai was extremely envious. She heard that the construction department had been guarding the drowning city for many years, but after so many years, no one had learned the sea tribe’s language. They were still in a state of half-understanding. It was very easy to misunderstand the language. This was because many people in the construction department had the foundation of the relevant hieroglyphs. As for the Salvation Society, the Truth Knights, the Takama-ga-hara, the Arctic army, and the Indian warriors, they could forget about it. Their language was not evolved from the hieroglyphs, and it was even more difficult to understand the language of the SEAFOLK. They often spent a lot of effort and spent a lot of money to smuggle out a few documents of the seafolk, but in the end, they had no idea how to translate them for one or two years. It was unbearable. “AH… I failed. The progress bar only increased by 10% .” Tian yucai pouted helplessly. “I’ll read it after a break. I’ll learn it sooner or later anyway. I’m going to read the other documents.” Lin Xuan said a few words and walked to the most luxurious bookshelf. The documents on this bookshelf were all the history of the royal family. Lin Xuan was very interested in the marine civilization. He really wanted to know what happened to the marine civilization at the end. Was it the same thing that happened to the Kunlun Palace and the Heavenly Dragon Temple? .. One day later, Lin Xuan rubbed his eyes and put down the documents. In one day, he finished reading all the historical documents of the marine royal family. From the first generation of the Sea King who made his fortune in the Sea of origin of the marine race to the last generation of the Sea King who killed himself on the throne in a drunken dream. In the blink of an eye, it was as if he had seen the rise and fall of a powerful race for ten thousand years. “I see. Everything Fits.” Lin Xuan remembered what Ji Ruyue had told him. This mystic realm was very unique, as if it was the fusion of two places. Drowning City, formerly known as Sea King City, was the core area of the sea tribe civilization. The Endless Sea was a boundless sea area in the far east of the world where Kunlun Palace was located. Now, a part of the endless sea was about to drown the city. “According to the documents, all the changes started when the sea of beginnings was contaminated by the Black Sea. The sea tribes tried to remedy it, but many elites of the royal family were buried in the Black Sea “In the end, the Black Sea devoured all the worlds under the control of the sea tribes and also the Sea King City, turning it into the city of death under the sea
