Meanwhile, Zuan traversed the underwater mountains. Although there was no magnificent Tomb of Ten Thousand Dragons here as we see in later generations, the mountains were still the burial grounds of many giant dragons.

Many dragons were guarding the area, strictly prohibiting any other creatures from approaching.

Zuan slightly altered his appearance, disguising himself as a dragon guard patrolling inside. In addition, his divine sense was vast, allowing him to avoid other dragons well in advance, so he was not discovered.

After wandering around, he discovered that many dragon tombs existed, but they were all rather rough and hasty. Basically, whoever died would find a mountain as their final resting place, without any other grand buildings.

"It seems that the Tomb of Ten Thousand Dragons was indeed built later." Zuan was quite familiar with the Tomb of Ten Thousand Dragons. He originally thought he could match it with later generations based on his memory, but unfortunately, it turned out he was overthinking it.

The world in this era was much larger than in later times, which meant that the topography and landforms had changed significantly.

Even though Zuan strained his eyes, he couldn't see any familiar places, let alone the triple traps found in the Tomb of Ten Thousand Dragons in later generations.

Looking back now, if the Dragon Palace hadn't been such a prominent target and its various magical formations hadn't possessed such unique auras, he probably wouldn't have been able to find it in the vast ocean.

In the end, he gave up on continuing his search for the Tomb of Ten Thousand Dragons and instead went to find the terrifying abyss at the bottom of the sea, which was the entrance to the Netherworld.

Such a huge abyss couldn't possibly have disappeared too, could it?

He was originally the lord of the Netherworld, and was extremely familiar with the aura of the Netherworld.

He soon wandered through the mountains and came to a deep trench.

He could sense that the entrance to the underworld was beneath these trenches.

The ocean trenches in this world are many times deeper than the Mariana Trench, the deepest trench on Earth in my previous life. The terrifying pressure of the seawater is enough to stop most living beings from getting close.

As Zaun descended into the trench, he encountered more and more dragons along the way.

He frowned slightly, thinking that only the powerful physique of the dragon race could withstand such terrifying pressure.

But why are there so many dragons here?

Before long, he was stopped by two dragon guards. Fortunately, he reacted quickly and found a reasonable excuse to get rid of them.

But looking at the countless dragon shadows that were faintly visible below, he knew that if he continued thinking, his identity would definitely be exposed.

These dragons gathered here as if guarding something beneath the trench, and he could sense various complex formations poised to be unleashed from all directions, some to defend against external enemies, and others to target enemies coming up from below the trench.

With his current mastery of formations, he can even distinguish that these formations are mainly for defense against what lies beneath the trench.

"How strange!" Zu'an wondered to himself. Could it be that the dragon race was preventing the creatures of the Netherworld from coming out of the abyss?

But I heard from the Emperor of Fengdu that the creatures in the Netherworld had already disappeared in ancient times.

Could it be that there are still living beings in the underworld of this world?

Thinking of this, Zu'an became somewhat excited. You see, although in later generations he was in charge of the Netherworld Grand Ceremony and became the Lord of the Netherworld, strictly speaking, he was a commander without troops.

The Yama, judges, and various officials and soldiers in the underworld have all disappeared, leaving only remnants of that era.

If we could make contact with the original inhabitants of the Netherworld, we might be able to resolve many long-standing mysteries.

However, seeing the heavily guarded situation below, he had to temporarily abandon the idea. Although he could transform into other people's appearances, the area below was clearly a forbidden zone, and no one was allowed to approach it. Even the Dragon King himself probably wouldn't allow anyone to go down there at will.

If you insist on it, it will definitely arouse suspicion.

Having just arrived in this world, and now without the support of the Law Beacon, he decided it was best to play it safe.

After taking a deep look at the situation in the trench below, Zuan turned and left.

He decided to contact the high-ranking members of the Sea Clan of this era to understand the basic situation before making any plans.

Speaking of which, I wonder if the king of the sea creatures in this era is the Dragon King. How can I convince them that I come from a world thousands of years in the future?

Most people would probably think I'm crazy.

My thoughts were racing all the way, and before I knew it, I had arrived at the Crystal Palace.

Looking at the magnificent palace floating in the middle of the ocean, Zaun smiled. Finally, he could see some traces of the future.

The Crystal Palace is surrounded by various defensive formations, and any non-sea creature that approaches will trigger an alarm immediately.

But this didn't stump Zuan. After all, he had been the Dragon King for a period of time and was very familiar with all the formations of the Crystal Palace.

Although this era is different, the fundamental principles remain the same. With his mastery of formations and the ability of the Sea God's Crown to control water, he quickly and silently infiltrated the Crystal Palace.

After wandering around the palace for a while, he quickly learned that in this era, the Dragon King was still the ruler of the sea tribes.

However, unlike later generations where one power dominates, this world's oceans have four Dragon Kings from the east, west, south, and north. The current owner of this Crystal Palace is the Dragon King of the East Sea, who is also the leader of the four Dragon Kings.

However, the strength of the other three sea dragon kings should not be underestimated. Normally, when there are any major events in the sea tribe, the four dragon kings negotiate and resolve them.

The four Dragon Kings had a very good relationship; they were practically inseparable, and they would generally make decisions together.

To his surprise, he also heard many rumors about the Mermaid Queen, saying that she was the most beautiful woman in the sea tribe, and that countless men had fallen at her feet.

It is said that the Four Dragon Kings were all her suitors, and even the former number one demon emperor in the world had pursued her madly, but none of them could win the beauty's heart.

However, the Demon Emperor is now dead, and the Dragon King of the East Sea has the best chance.

Thinking of the outrageous praises the guys in the palace gave the mermaid queen, Zu An wondered if she was even human. Perhaps only an imagined work of art could achieve that.

Zaun was somewhat skeptical of the legendary beauty, but was quite curious about the title of Mermaid Queen.

Speaking of which, I have an inexplicable bond with the Mermaid Queen. Whether it's Shang Hongyu or Shang Liuyu, we've all had unforgettable experiences together.

I wonder if this mermaid queen might be the ancestor of the two sisters?

The thought of their expressions when they return and find out they've encountered the mermaid queen of this era must be quite a sight.

Let's go see the Dragon King first, at least to know what he looks like, it might come in handy later.

The deeper he went into the palace, the more heavily guarded he became, with guards rushing about everywhere. He could vaguely hear them talking about how the assassin had been captured.

"What kind of assassin has come to the Dragon Palace? Is it a demon?" Zu'an wondered to himself.

Suddenly he stopped in his tracks. The next second, a cold dagger was pressed against his lower back, and at the same time, a soft, ethereal female voice rang out: "Don't move. Now you are my prisoner. Do as I say."

Zuan chuckled. Although he didn’t turn around, he could still “see” a woman behind him through his divine sense. She was dressed as a palace maid and her face was covered. Could she be the assassin that the guards had just been talking about?
