On the walls of the entire underground palace, there are all kinds of murals showing the ancient era, and these murals have benefited Xu Luo a lot and learned a lot of information about the ancient era.

On the mural, there are huge black beasts as huge as mountains, with three heads, covered with scales, and their appearance is hideous and terrifying, and there are also golden birds that spread their wings and soar in the sky, covering the sky and the sun, like a golden cloud.

There is a cyan dragon that winds up to the sky, huge and friendless, and a fiery red, as if you are in a phoenix in a sea of fire.

There are also purple unicorns with majestic appearances, one paw is bigger than a mountain range, soaring through the clouds!

and all kinds of ancient beasts that Xu Luo couldn't name, all of which were huge.

If you hadn't seen the black giant tiger and the golden bird, it would be hard to believe that these behemoths on the murals were all real creatures that once lived in this world.

"The years are merciless, and how many powerful existences have been worn out. Xu Luo looked at the mural and whispered to himself.

The whole underground palace is too big, and like a labyrinth, there are such tall corridors everywhere, and on both sides of the corridors, ancient murals are painted.

Although many thousands of years have passed, these murals are still lifelike and colorful, as if they were just painted yesterday.

The walls were inlaid with large spirit stones, emitting a soft glow, enveloping the murals on the walls in a mysterious light.

Some of the creatures on the murals are strange and ferocious, and through the murals, they all exude a majestic aura that looks at the world, as if they can jump out of the mural at any time.

Those creatures all brought great pressure to Xu Luo, and it seemed that a few more glances were a kind of blasphemy against them.

"If these creatures had ever appeared in this world, the days of those ancient ancestors would ...... I'm afraid it's not that easy. Xu Luo thought in his heart while resisting the aura emanating from those terrifying creatures on the mural.

There are also many ancient ancestors on the murals, and their bodies are also very huge, which is too different from the current human beings in size, although they are all similar in appearance, but they seem to be two different races.

In one of the paintings, a giant of extremely tall and muscular stature, shirtless, with a glow and strength on his bronzed skin. With a huge black tiger skin around his waist and a black iron rod in his hand, he raised his arms and roared to the sky.

At the feet of the giant, a dead beast was stepping on, and the mountain peak next to it looked so small in front of the dead beast.

Next to this picture, there is another mural about the ancient ancestors.

It was a giant also dressed in animal skins, holding a bow made of unknown material as black as ink, and looking up to the sky to shoot arrows.

High in the sky, a phoenix covered in flames spread its wings, covering the sky and the sun, an arrow was inserted into the body of the phoenix, the phoenix's eyes showed an extremely angry light, but it looked like it was falling from the sky to the sky.

Xu Luo couldn't help but gasp and said, "Could it be that in that era, there was really such a warrior who could shoot a phoenix with a bow?"

Think about it...... Is there really such a possibility, how was a dungeon of this scale built?

"It's really a brilliant and glorious era, it's fascinating!" Xu Luo couldn't help but sigh softly.

Xu Luo walked all the way, looked all the way, and suddenly, his eyes were attracted by an ancient star map.

On the top of the tall corridor, an ancient star map is drawn, on which is a vast starry sky, and behind the starry sky, there is an incomparably deep dark universe, boundless.

This ancient star map is extremely realistically drawn, just like the real starry sky, and a grand and vast aura is blowing in the face!

There's even a hint of star power on it!

Xu Luo's gaze couldn't help but fall to the middle of the star map, where it ...... It is the location of the Big Dipper.

Unlike the great pressure brought to him by those ancient ancestors and giant beasts before, Xu Luo looked at this ancient star map, and suddenly felt a sense of closeness in his heart. This feeling is indescribable, like a wanderer who travels far away, returning to his hometown after many years, the feeling of being close to his hometown makes Xu Luo have mixed feelings in his heart.

The seven Big Dipper stars on the star map seem to have come from eternity, after endless vicissitudes of life, like the king of the seven starry sky, living in the center of the starry sky.

However, when Xu Luo's gaze swept to the stars of the Big Dipper, there was endless surprise in his eyes.

It's right next to Kaiyang...... Actually...... And one more star!

The star's light was a little dim, and at first glance it looked like an ordinary star in the endless starry sky, but this star ...... But it is connected to the Big Dipper...... Eighth star!

For some reason, when Xu Luo saw the star, an extremely complicated emotion surged deep in his heart.

There is joy, there is sadness, there is throbbing in the depths of the soul, and more, but it is an indescribable feeling.

Xu Luo didn't know why his emotions came from, he stared at the star, and the star seemed to be staring at him.

Thinking instantly cut through the endless years of eternity, and a huge picture appeared in Xu Luo's mind.

It was a starry sky!

The stars are shining in the sky, big stars are hanging in the sky, and next to the Kaiyang star of the Big Dipper, a big star with a slightly dim light flickers and flickers, making people unpredictable.

Xu Luo stared at the ancient star map on the wall in a distracted manner, full of complexity and indescribable.

After a long time, Xu Luo shook his head slightly, stretched out his hand, rubbed his forehead a few times, his heart was full of doubts, and muttered: "Big Dipper...... There are only seven stars, this ancient star map is so weird, how can there be an eighth star? Could it be that the ancients accidentally drew an extra star when they drew this star map?"

Saying that, Xu Luo couldn't help but ask the Shaking Light Star Soul, "Shaking Light, what's going on with this star?"

In the dantian, there was silence, and the shaking light star did not give him any answer.

"Hehe......" Xu Luo chuckled a few times, then shook his head, trying to drive out the complex emotions in his heart, and then said: "Perhaps, it was the ancients who were naughty, and they drew snakes to add to it." ”

As he spoke, Xu Luo took a step and continued to walk forward, but deep in his heart, that complex emotion still existed and did not diminish in the slightest.

"One more star, one less, follow me...... What does it matter?"

In the huge underground palace passage, Xu Luo's voice echoed, and the ancient star map on the wall was silent, silently experiencing the eternal years.

"Perhaps...... In ancient times, Beidou had an eighth star...... Who knows...... Maybe it once existed, but then it was annihilated. ”

The emaciated figure walked farther and farther, and finally, disappeared at the end of the corridor of the underground palace.

Xu Luo's heart was full of mixed feelings, he had a lot of questions, but he didn't know who could answer him, and the silence of the Shaking Star Soul made Xu Luo's heart full of doubts. But right now, it doesn't seem to be the time to be curious, because Xu Luo, at the end of this corridor, saw a huge temple!

Here, it should be the central area of this underground palace, the temple is extremely huge, thousands of meters high, and the radius is dozens of miles!

On both sides of the temple, there are statues of ancient ancestors, and Xu Luo saw the ancient warriors who appeared on the murals in the statues.

The statues are lifelike, their faces and expressions are clearly visible, and they are full of joy, anger and sorrow.

They are like gods, guarding this ancient temple that has endured for so many years.

At the end of the temple, at the top, there is a huge golden throne!

The seats are empty.

"I don't know who can sit in that position. Xu Luo looked at the throne, and his heart was full of emotion, as if he had returned to that glorious and brilliant ancient era, a giant leader full of majesty, sitting on that throne, accepting the worship of all the people.

The walls around the temple are also covered with murals, but these murals are not any kind of creatures, nor ancient giants, but some mysterious and complex patterns, and the complex texture exudes an incomparably mysterious atmosphere.

It seems to contain a magical rhyme!

Xu Luo only glanced at it a few times, and felt as if his heart was being pulled by a mysterious and strange force, and it was thumping, beating faster and faster, as if it was about to be picked out of his throat.

Xu Luo hurriedly looked away, his heart full of horror.

"What the hell is this drawing, and why is it so weird?"

Then, Xu Luo felt that the amount of force in his body began to run automatically according to the route of the patterns he had just seen, and his blood was almost in an instant...... It's boiling!

An incomparably powerful force burst out from Xu Luo's dantian in an instant.

Rumble!

Xu Luo's body uncontrollably erupted into one after another extremely powerful and powerful forces, shooting towards the surroundings of the temple.

"This is **!" Xu Luo exclaimed.

The Shadow Light Shaking Heart Method instantly worked automatically, guiding the powerful force in his body to move around his body.

Xu Luo felt that his strength was increasing rapidly, and the speed was so fast that he couldn't believe it, and even felt a little frightened!

Because this force is so large that it is difficult for him to control himself, as if he may burst his body at any time!

The Kaiyang Star Soul suddenly lit up, exuding a soft force that suppressed the surging force in Xu Luo's body in an instant.

Then, the Shaking Star Soul stopped running automatically, and the domineering and vast power also became docile, and gradually, it returned to calm.

"It's amazing!" Xu Luo exclaimed softly, feeling the strength in his body, there was a difference between heaven and earth from before, and his realm, unconsciously, had risen by a small step!

Stood on the second small step of the Transformation Realm!

Xu Luo released the breath in his body, and immediately, the corners of his mouth showed a happy smile.

The breath of the Eighth Order Sword Venerable!

Looking at the mysterious and complex patterns on the wall, Xu Luo's eyes were full of shock, and then, there was ecstasy!

Just looking at a corner, there is such an amazing harvest, if you can understand all the patterns on the entire wall, what kind of improvement will you get?

At this moment, Xu Luo almost forgot about the Chaos Peach Tree, which could be called a miracle medicine, and was bent on understanding all the patterns on the walls around the temple.

A moment later, Xu Luowa spurted out a mouthful of blood, his face was stupid, and he muttered: "The greedy heart really can't ......."
