While advancing underwater, the thirteen innate experts of Qinghu Island also encountered two demon beasts. One of them escaped quickly, while the other was a fish-type demon beast that tried to launch a sneak attack but was beheaded by Gu Yong himself. Teng Qingshan didn't know the name of this demon beast... However, judging from its appearance, it wasn't particularly strong.

  "The difference between a monster and a demon is also very big." Teng Qing Shan sighed silently.

  Like the pre-metamorphic Red Scale Beast, Black Iron Centipede, ordinary Iron Armed Ape, their strength is comparable to that of the strong ones in the Earth Ranking, and even slightly stronger.

  The transformed Red Scale Beast, the Iron Arm Ape, and that fish-like demon beast should be comparable to the 'Pre-Heaven Void Elixir' and 'Pre-Heaven Solid Elixir' level.

  Iron Arm Ape King and Iron Wire Snake are comparable to the strongest of the Pre-Heaven Golden Dan humans.

  As for the Violet Light Dragon, it's even stronger than the Pre-Heaven Golden Elixir. Perhaps only the top few individuals on the Heavenly Rankings can compare with the Violet Light Dragon.

  ……

  There are some beasts that are born with a stronger physical quality than humans. In the same dense heaven and earth spiritual energy environment, among humans who can give birth to strong people, there are also strong ones among beasts - demon beasts! These demon beasts, once they have wisdom, can reach an unimaginable realm. Of course—

  Monsters and humans are still different, humans have Yu Huang, Qinling Tian Emperor, Shakyamuni, Li Taibai and other invincible beings. However, among monsters, although there are also extremely powerful and frightening ones, they are slightly inferior to Yu Huang and the others.

  "Landlord, what's ahead!"

  After advancing for more than half a time at the bottom of the water, the thirteen strong men of Qinghu Island suddenly discovered a underwater building! Because it was pitch black, they could only rely on the pre-heavenly true yuan halo to watch. The thirteen strong men of Qinghu Island, even with their halos stacked on top of each other, could only see within a distance of ten zhang.

  Within a range of ten zhang.

  A towering structure about two zhang high, with an unknown length, appeared in the field of vision, its surface entirely covered with rotting aquatic plants.

  "Let me see." Zhao Danchen walked over and wiped his hand.

  In an instant, a golden prenatal true yuan flew out of his hand, like a lotus leaf hitting the surface of the building, and suddenly exploded!

  A low rumbling sound echoed continuously: "Rumble, rumble, rumble..."

  And the muddy surface of this underwater building was also shaken off by the explosion of the Primordial Yuan, and in an instant, the surrounding waters were murky. However, in this murky water, the thirteen Primordial strongmen from Qinghu Island were close to the surface of the underwater building, taking a closer look...

  "What material is this? The bluish-green wall?"

  Thirteen congenital strongmen on Qinghu Island were dumbfounded.

  "It's truly unbelievable! Under this enormous pressure at the bottom of the lake, I don't know how many years have passed. And yet, this wall doesn't have a single scratch."

  "Look, Island Master, this wall is actually a single piece! It's not made of individual bricks."

  "How is this possible!"

  "What we can see with our eyes is a wall that's nearly ten zhang wide. But the entire wall is actually one piece! A cyan-colored wall? It's not stone, it's not steel...... what exactly is this?"

  "This, this must be the Yu Huang Palace, it must be!"

  A single wall was enough to stun thirteen congenital strongmen, and in the nine states of the land, they had never seen such a material.

  "Hurry up and find the gate of this palace." The thirteen Pre-Heavenly experts immediately moved forward along the wall, and when these thirteen people left, Teng Qing Shan also arrived at this wall.

  Yu Huang's palace? Teng Qing Shan carefully examined the wall and even stroked it with his hand, smooth and icy cold.

  "It's as smooth as a tile from a past life, the most bizarre thing is... the entire wall surface is completely integrated. There isn't even a single seam." Teng Qing Shan's gaze swept across the top of the underwater palace, "And that Zhao Dan Chen's innate true yuan didn't leave even a small dent on top."

  Hong Qingshan felt unbelievable.

  "Master once said that the demon monk Xiang Fan was invincible in the world. But compared to Yu Huang and others, there is still a gap! Yu Huang and others can unify the world with just one person's power." Teng Qing remembered clearly, "One person's power unifying the world... What kind of means do Yu Huang and others have? How can they create such an unimaginable palace!"

  "If this is a palace, and it's Yu Huang's palace, then it's really too terrifying!"

  Yu Huang was a figure from several thousand years ago.

  That is to say...

  This palace has existed at the bottom of the water for thousands of years, and these walls have not been damaged in any way. Even in modern society, it would be impossible to achieve this!

  "This palace, it's not something that can be built by a large number of people." Teng Qing Shan was very certain. "Could it be... that Yu Huang built it alone?" As for the ancient 'Yu Huang', Teng Qing Shan really didn't understand his methods, but being able to destroy a tall mountain with just five axe strikes was indeed a divine technique.

  At this moment, the thirteen people of Qinghu Island had already walked seventy zhang away.

  Teng Qing Shan immediately followed up.

  ……

  As they continued to move forward around the palace, with the passage of time, the thirteen congenital strongmen on Qinghu Island were also shocked to discover that this underwater palace was actually huge!

  "Palace Gate!"

  "Master of the island, ahead is the palace gate!"

  The strong men of Qinghu Island were somewhat excited, and Teng Qing Shan was also looking at the palace gate from afar. The people of Qinghu Island had to get closer to see it clearly... But Teng Qing Shan could see it clearly even tens of meters away... The palace gate was over 30 meters wide, and in front of the palace gate there was a tall, square stone-like object.

  "Hmm..." Zhao Danchen arrived in front of this 'stone tablet', and wiped his right hand.

  Buzz——all the mud has been scattered away.

  Exposed a bluestone monument with four large characters on it - "Tian Hong Shui Gong"!

  "Tian Hong Shui Gong?" Similarly, Gu Yong, who was approaching, looked at these four words with doubt.

  "Island Master." Zhao Dan Chen smiled and said, "Yu Huang and the others have all reached the highest realm, breaking through the void, reaching the perfect self. This Tian Hong Water Palace should be Yu Huang's creation! Apart from the four strongest in history, no one can borrow the power of heaven and earth to create this palace. It must be Yu Huang... probably also spent a lot of heart and blood to create it."

  Distant green hills listen carefully.

  "What is the highest boundary? Breaking emptiness? Self-perfection?" Deng Qing Shan's heart was filled with doubts.

  Fantasy Realm, this is now the highest in the nine states of the mainland.

  Of course, without Yu Huang and Qin Ling Tian Di, those four extremely powerful beings, the Void Realm is the highest.

  "Alas, even the Void Realm is beyond my reach. Let alone Yu Huang and those at that extremely high level." Gu Yong sighed, "A thousand-meter-high mountain can be split with five axe chops. A hundred-meter-wide river can be stopped with one palm! Thousands of troops and horses before them are just child's play! Wanting to unify the world is as simple as unifying the world... Absolutely invincible."

  "Zhaodan Chen also sighed: "The void of the virtual world, is the void of empty space, and also the void of nothingness. The body is round and complete, the spirit enters the void... Inside the body is a perfect circle, a void, infinite perfection. And the external boundless heaven and earth, are also a void, vast and endless... Life is complete, breaking through the void, reaching the highest realm."

  "It's easy to say, anyone can say it. But to actually achieve it, that's too difficult." Gu Yong shook his head and sighed.

  "We can't even touch the edge of the virtual realm, let alone Yu Huang and their level." Zhao Dan Chen also sighed, it was really too far away.

  ……

  Teng Qing Shan also remembered these few words clearly.

  "Let's go in."

  Gu Yong and thirteen others immediately went close to the palace gate.

  "Hum~~~" As the thirteen people approached the palace gate for an instant, the entire palace gate suddenly emitted a golden light.

  "Halt." Gu Yong shouted, thirteen people standing outside the palace gate, didn't dare to go in.

  "A low, muffled roar echoed from within the Yu Huang Palace, a sound that shook one's very soul. The thirteen Pre-Heavenly strongmen of Qing Hu Island all retreated several zhang in unison, gathering together as they stared at the gates of the Tian Hong Water Palace."

  A golden turtle about three zhang long appeared at the palace gate.

  "Golden Dragon Turtle?" Several of the thirteen people on Qinghu Island couldn't help but blurt out in surprise.

  "Dragon Turtle? Golden Dragon Turtle?" Teng Qing Shan also stared with wide eyes at the only three-zhang-long dragon turtle, according to the book records.

  Dragon Turtle: Known as the most defensive monster, with infinite strength! Any mature Dragon Turtle is generally cyan in color and tens of meters long, like a small mountain. Even a strong cultivator who has formed the Golden Elixir can barely fight it. But once the cyan Dragon Turtle transforms into a golden Dragon Turtle, its body will shrink dramatically to become a 3-4 meter long golden Dragon Turtle... If you encounter one, there's only one word - RUN!

  "Golden Dragon Turtle?" Teng Qing Shan secretly rejoiced, "Hmph, a hybrid from Qing Hu Island, the Yu Huang Palace is not that easy to enter? This Golden Dragon Turtle, I'm afraid it's a strong being comparable to a human Virtual Realm!"

  ……

  Only then did the master of Qinghu Island, 'Guyong', step forward and bow his head, saying: "Senior Longgui, we obtained the Yu Huang treasure map by order of Yu Huang to retrieve the treasure. Please let us in." As he spoke, he took out the black iron treasure map from his bosom and pointed towards the palace.

  The monster is extremely intelligent and can transform into a golden dragon turtle, it's unknown how many years it has existed.

  It's likely that this dragon turtle was already in existence during the time of Yu Huang.

  So forcing won't work, can only rely on softness. Maybe the golden turtle will really let go.

  The golden dragon turtle let out a low growl and suddenly opened its mouth wide.

  "Boom!"

  A mighty gust of air shot out from its mouth, and in an instant, three visible masses of air shot towards the thirteen powerhouses on Qinghu Island like lightning. It's worth noting that this golden dragon turtle has infinite strength and impenetrable defense, with a body as its main attribute. An ordinary human can blow away paper with one breath, but this golden dragon turtle can shatter boulders with just one blast of air.

  Of course, spouting air masses is obviously just a warning!

  Golden tortoise, too lazy to move.

  "Boom!" "Boom!" "Boom!"

  The water flows violently, and three groups of air masses shoot out.

  "Get out of the way!" Gu Yong shouted loudly, but the speed of the air mass was too fast, and two innate experts dodged too late.

  "Pong!" "Pong!"

  The two of them both used knives and parried towards the air mass. The two were shaken in two directions, among which the gray-robed Lian Changlao was shaken towards the direction of Teng Qing Mountain.

  "Boom!" The grey-robed Lian Zhang was sent flying tens of meters away.

  "This golden dragon turtle, just by spitting a mouthful of air, can hurt me." Lian Zhang felt this to be inconceivable. After all, he was also a Xiantian Real Dan strongman. Suddenly, Lian Zhang felt the water flow behind him surge violently, and his heart trembled involuntarily. He dodged in an instant, while turning his head around.

  Pfft!

  A shadowy figure directly inserted into his skull!

  "Ahh!" A mournful and piercing cry rang out.

  Lian Changlao saw nothing but a pair of sharp and murderous eyes before his death.

  Hong Qingshan pulled his hand out of Lian Changlao's grasp.

  "The first one, Xiantian Zhendan!"

  Teng Qing Shan immediately retreated quietly, and in absolute darkness, without using his innate True Yuan, Teng Qing Shan was completely undetectable to others, making him the most terrifying assassin!

  ……

  Hearing the mournful and miserable cries, Gu Yong and the others were greatly shocked.

  "We retreat first." Gu Yong shouted, they didn't dare confront the Golden Dragon Tortoise.

  A golden dragon turtle, a pair of pupils shining with green light scanned a group of people, raised its head and let out a loud roar.

  "Ahhh~~~~" The roar echoed outwards.

  All of a sudden

  "Roar!" "Roar!" "Roar!"...

  Only the sound of roaring voices came from within the Yu Huang Palace, and the roar responded to the golden dragon turtle's roar. When they heard this roar, Gu Yong and the twelve pre-heavenly strong men all changed their faces greatly.

  "Heavens! This isn't the Yu Huang Palace... this is a lair of demonic beasts!" The woman in purple robes had her eyes wide with shock.
