Meanwhile, Zu An was moving through the seafloor mountains. Even though he didn’t see the grand and magnificent Tomb of Ten Thousand Dragons, there were still many giant dragon bones buried within. There were many members of the Dragon race standing guard nearby, strictly prohibiting any creatures from approaching. Zu An changed his appearance a bit to resemble one of the guards patrolling this area. Now that his divine sense had such a wide scope, he was able to avoid most of the guards, so he wasn’t noticed. After walking around for a bit, he saw that there were many dragon burial mounds, placed in a relatively rough and careless manner. It seemed that whenever one was about to die, they would find a mountain as their place of eternal rest. There were no grand buildings or the like. “It seems the Tomb of Ten Thousand Dragons was something built afterward after all,” Zu An muttered. He was already extremely familiar with the tomb. He'd thought that he would be able to match his memories to this place, but reality proved that he had assumed too much. The world of this age was far larger than that of later generations, which also meant that the topography had changed greatly. Even Zu An’s eyes were becoming a bit sore from all the searching; he couldn’t find any familiar areas, let alone the three great trial regions he'd experienced before. Now that he thought about it, if it wasn’t because the Dragon Palace was just too conspicuous and had all kinds of very special formation energies, he likely wouldn't have even been able to find it amid this boundless sea. In the end, he gave up on continuing the search for the Tomb of Ten Thousand Dragons, and instead tried to find the terrifying ocean abyss that marked the entrance to the Underworld. There was no way such a huge abyss could just vanish into thin air too, right? He was the lord of the underworld to begin with, so he was especially familiar with its energy. Thus, he quickly moved within the mountains and arrived at a deep trench. He could sense that the entrance to the Underworld was below. This ocean trench was countless times deeper than the Mariana Trench of his previous world. The terrifying ocean pressure was enough to stop most creatures who approached. Zu An dove into the trench. The dragon guards he encountered increased in number. He frowned slightly. This pressure was something likely only the Dragon race’s tough bodies could withstand. But why were there so many dragons here? Shortly after, he was stopped by two dragon guards. Fortunately, he reacted quickly and found some reasons to dispel their concerns. However, he could see more and more dragons below. He realized that if he wanted to head down any further, he would definitely be exposed. These dragons seemed to all be gathering here to guard against something in the ocean depths. Furthermore, he could tell that there were powerful formations accumulating energy all around. There were some for guarding against enemies on this side, but there were some for any enemies that could come up from below. With his current skill in formations, he could even tell that these formations were mainly to defend against things from below. It really is strange! Zu An thought to himself. Could it be that the Dragon race were guarding against creatures coming from hell? But judging from what the Necropolis Emperor told him, hell’s creatures had already disappeared a long time ago. Could it be that there were still creatures living in this world’s Underworld? Zu An was becoming a bit excited. After all, even though he had the Book of Life and Death and had become the lord of the underworld, strictly speaking, it was a commander position with a barren pole. The kings of hell, underworld judges, and all kinds of deities with various posts were gone. There were only some remnants from the past left. If he could interact with the indigenous residents of hell, perhaps he'd be able to get rid of some of his confusion. But when he saw the heavy security before his eyes, he immediately gave up on this thought. Even though he could change into someone else, the formations below were clearly off-limits and no one was allowed to approach. Even the Dragon King himself could be refused entry if he tried to casually head down. It would only incur suspicion if he persisted with the issue. He had just arrived in this world and didn’t have the help of the law beacon anymore. Thus, he decided to be a bit more careful for now. He gave the trench below a look, then turned around to leave. He decided to interact with the higher-ups of the Ocean races of this age first, then make some plans after he had some idea of the current situation first. He wondered if the king of the Ocean races of this age was also a Dragon King. Also, just how was he going to make them trust him? Could he say that he came from this world, but thousands of years later? He would probably just be treated as a lunatic, right? … Along the way, Zu An was immersed in thought. Just like that, he found himself at the crystal palace. As he looked at the magnificent palace that floated in the middle of the sea, a smile appeared on his face. He recognized some aspects from his world. There were all kinds of defensive formations around the palace. The presence of those who weren't of the Ocean races would immediately be reported as soon as they approached. But that didn’t stop Zu An at all. He had, after all, served as the Dragon King of a different age, so he was very familiar with these defensive formations. He wandered around the palace for a bit and quickly found out that there was still a Dragon King ruling over the Ocean races of this age. However, it was very different from what he knew in his world. This world’s seas had four powerful Dragon Kings; the ruler of this Crystal Palace was only the East Sea Dragon King, but he was the boss of the four Dragon Kings. But the other three Dragon Kings’ strength weren’t to be underestimated either. The important matters of the Ocean races were all decided after the four Dragon Kings held a discussion together. Additionally, the four Dragon Kings all had a good relationship and had similar viewpoints. They almost always made similar decisions. 𐍂� What was surprising was that he had heard quite a few rumors surrounding the Mermaid Queen, claiming that she was the number one beauty of the Ocean races. Countless men had tried to court her. It was rumored that even the four powerful Dragon Kings were her pursuers, and that even the previous strongest being under the heavens, the Fiend Emperor, was a mad pursuer of hers. However, none of them had been able to take her home as their wife. But the Fiend Emperor had already perished, so the East Sea Dragon King had the highest hopes of succeeding on this front. When he thought about the ridiculous descriptions those in the palace had for the Mermaid Queen, Zu An was starting to wonder if she was still a person. This was already on a level only works of art could reach, right? As for himself, he didn’t really care much about this legendary beauty. He was actually more curious about her title as the Mermaid Queen. He had a mysterious connection with mermaid queens, after all. Whether it was Shang Hongyu or Shang Liuyu, both of them were responsible for unforgettable memories. He wondered if this Mermaid Queen was an ancestor of those two sisters. He was certain that once he returned, and they found out that he'd encountered this age’s mermaid queen, their expressions would be really amazing. He decided to pay this Dragon King a visit first. At the very least, he had to find out what this guy looked like, since that could be helpful later in his transformations. … The further inside the palace he went, the stricter the security became. There were guards moving around hastily. Hearing their conversations, he picked up that there seemed to have been an assassin that had been captured. What assassin could sneak all the way into the Dragon Palace? Was it a monster? Zu An secretly thought to himself. He suddenly stopped. A second later, an ice-cold dagger was pressed against his lower back. At the same time, a gentle and clear female voice said, “Don’t move. You have now become my captive. Do exactly what I tell you to.” Zu An couldn't help but laugh. Even though he didn’t turn around, with his divine will, he could still ‘see’ that it was a woman behind him. She was dressed in a palace maid uniform and even had a mask on. Could this be that rumored assassin those guards were talking about?
