There was silence in the Dragon City of Nuoda, even though it was the place where the dragon clan who had dominated the Xuanyuan Continent lived for a while, but it still could not escape the erosion of time.

The large, lavish wooden windows were crumbling, and the pitted walls were covered with moss.

A white figure walked down the empty street, and the sound of sparse footsteps echoed along the wall, adding a little more popularity to the dead city.

Behind, two sneaky figures silently followed behind the young man in white. The pace moved slightly, and I was very careful not to make a sound!

"Where the hell is this guy going?"

After following the rear for a long time, the doubts in Lu Yun's heart became more and more intense.

The behavior of the young man in white in front of him was very strange, and after entering the city, he didn't seem to be curious about the things in the city. Without stopping, he walked directly along the avenue in the city without slowing down, as if he had a goal in mind!

Finally, after walking behind the young man in white for nearly an hour, the young man in white, who had been walking non-stop, finally stopped.

And in front of her was the sky-high tower that looked extremely conspicuous outside the city!

I don't know how many floors the giant tower has, and it looks very tall from the ground to the clouds. It is also a little out of place with many surrounding buildings.

And from the outside, it seems that the age of this giant tower is not very long. The body of the tower is as smooth as jade, and there is not a trace of dust attached to it. Moss covered almost every building in the city, and there was no trace of it on the tower.

What's even more incredible is that the size of the door frame of the giant tower in front of you is not ten or twenty meters high like those surrounding buildings. On the contrary, it seems to be designed according to the height of a human being, and the entire gate is only more than two meters high.

On the door frame, there are two big words "Dragon Prison"!

This strange building was out of place with its surroundings, but the eyes of the young man in white never showed the slightest surprise.

Walking slowly to the door, his hands as white as white jade slowly pushed towards the two wooden gates.

"Squeak~"

There was a tooth-aching sound, and the gate of the giant tower, which had been sealed for many years, was pushed open again. The dust accumulated in the cracks of the door was scattered, floating in the air like a mist, invisibly, as if adding a little strange and mysterious color to the giant tower.

"Whew~Whew~"

With a flick of the sleeve, a breeze blows away all the dust that fills the air.

Frowning slightly, the young man in white slowly walked into the tower. Looking at the scene in the tower, a touch of excitement gradually rose in his eyes!

"Heh~"

Laughing softly, the white-clothed young man who stepped into the tower did not climb up the stairs inside, but took a slight step towards the corner of the wall somewhere in the tower.

"Squeak~"

There was a slight sound, and the figure of the young man in white suddenly disappeared into the tower.

At the same time, Lu Yun and the two who were following closely on the other side rushed into the giant tower quickly after hearing the movement coming from the tower!

But in front of him, he has already lost the trace of the young man in white!

"Eh, what about people?"

Looking at the empty space inside the empty tower, Lu Yun's heart couldn't help but rise a little vigilant! The spiritual energy in his body was ready to attack, ready to deal with the attack that could come at any time!

"Lu Yun, don't be so nervous, look there. ”

patted Lu Yun's back and motioned for him to relax. Ling Qingyu let out a slow voice and stretched out his hand to the dusty ground!

Hearing this, Lu Yun looked in the direction of Ling Qingyu's finger. But I saw that on top of the thick dust accumulated on the ground, a row of petite footprints stretched along the gate to the corner of the wall somewhere in the tower.

"What is this?"

Looking at the footprints on the ground, Lu Yun also suddenly understood what Ling Qingyu meant. Between the words, he slowly leaned towards the corner of the wall to which the footprints were pointing with a vigilant face!

"Smack~"

The palm of the hand touches the wall, making a soft sound. Lu Yun quickly took a few steps back as if he were shocked, but found that there was no such thing as an imaginary mechanism on the wall.

"Hey, look that scares you! Surprised, do you look like a man?"

Ling Qingyu stretched out his hand and pushed Lu Yun, and said a little ruthlessly.

"Cut! What do you know? I'm cautious, cautious, don't you understand?"

Listening to Ling Qingyu's ridicule, Lu Yun rolled his eyes in disdain, and raised his head and said angrily.

"Hmph, shameless guy!"

Glancing at Lu Yun a little helplessly, Ling Qingyu snorted lightly. pushed away Lu Yun in front of him, walked slowly to the wall, and probed carefully with his hand on the wall.

"Huh... You!"

Lu Yun, who was pushed aside, stabilized his figure, and just wanted to say something, but suddenly heard a soft sound from the wall!

"Click!"

As a piece of masonry in the wall was pressed into the wall by Ling Qingyu, the sound of masonry moving suddenly came from the old wall!

"Click~Click~!"

After a loud noise, the otherwise flat walls cracked suddenly!

Gradually, a dark passage that was so dim that it could allow one person to pass through appeared in front of the two of them.

"It's... How did you do that?"

Looking at the dark path that suddenly appeared in front of him, Lu Yun was so shocked that he couldn't help but open his mouth wide, and his face couldn't stop being surprised!

"Cut! It's just an ordinary secret door mechanism, as for all the fuss?"

Ling Qingyu slowly stood up from the ground and glanced at Lu Yun angrily.

"Forehead ....."

Lu Yun was overwhelmed by Ling Qingyu's words, and he couldn't speak for a long time with his mouth open, so he could only relieve the embarrassment by changing the topic.

"Hey, don't talk about it! Let's hurry up, I feel that the young man in white is a little not simple, I'm afraid there will be some conspiracy here!"

With that, Lu Yun immediately set off and walked quickly into the dark passage. But that somewhat hasty figure, no matter how you look at it, it looks like you want to escape.

"Heh~"

Looking at Lu Yun's disappearing figure, Ling Qingyu smiled softly and also set off to follow.

"Turn on IR Perspective Mode!"

There was not a trace of light in the dim dark passage, and because he was afraid that the young man in white would find out the traces of the two of them, Lu Yun did not dare to take out the strong light in the storage space to illuminate the way. I can only silently recite to the God of War system in my heart, and turn on the infrared mode!

"Whew~"

A burst of warmth hit his eyes, and the scene in front of him suddenly changed greatly!

And with the help of the infrared perspective mode, through the darkness, Lu Yun also discovered the figure of the young man in white!

In the dim dark passage, a slight glimmer of light emanated. Although it can't illuminate the entire dark passage, it is enough to illuminate the road ahead for the young man in white!

After walking along the narrow dark passage for nearly ten minutes, a glimmer of light appeared in front of the young man in white!

With joy in his heart, the young man in white walked forward quickly. When you step into that glimmer of light, the vision in front of you is instantly brightened!

At the end of that dark passage, there was a very huge void!

The cave is extremely empty, and the ceiling is so high that it is a little blurry to look up. But what makes people feel a little strange is that for some reason, there are many strange symbols carved around the empty cave wall. A faint glow shines through the symbols on the cave wall, illuminating the empty cave a little!

If Lu Yun was here, he would definitely be very surprised!

Because all the inscriptions on the walls of the cave are high-level forbidden inscriptions, large and small!

What is the concept of so many high-level inscriptions?

As one of the most difficult inscriptions to carve among the six major inscriptions, the Forbidden Inscription is many times more difficult than the previous Hidden Spirit Array! If you want to learn Forbidden Inscriptions, the minimum requirement for the entry level is to have the cultivation of the elixir period!

And what is the concept of filling this cave with high-level forbidden inscriptions?

Even if hundreds of Spirit Infant powerhouses attacked at the same time, it would take at least nearly a few months to complete!

Among them, the manpower and material resources consumed are comparable to sky-high prices!

Why did it take so much money to build such a great array, and what was sealed in this cave that could make the writer so excited?

He even didn't hesitate to build such a tall giant tower in this dragon city to hide people's eyes!

Walking in the empty cave, wisps of light of different colors were reflected from the inscription array engraved on the cave wall, reflecting the white clothes of the young man in white into colorful colors!

All kinds of glimmers of light almost filled the entire cave, but there was only one place, and it was still so dark!

"Click~Click~"

There was a sound of footsteps, looking at the darkness in the cave, and a burst of excitement suddenly flashed in the eyes of the young man in white! But that somewhat pale face also proved the fear of the young man in white for the things hidden in the darkness!

"Zhao Ling'er, the Zhao clan of the Xuanyuan Continent, come to visit!"

Looking at the darkness inside the cave, the young man in white suddenly fell to his knees! He opened his mouth slightly, and the voice from his mouth was not as sharp as before. When I heard it, the sound was as crisp as a silver bell, and just listening to it made people feel as comfortable as a spring breeze.

The young man in white who called himself Zhao Lin before turned out to be a daughter!

"Zhao Ling'er of the Zhao family, come and pay a visit!"

He knelt on the ground and stood still for a long time, seeing that there was no reaction in the darkness of the cave. Zhao Ling'er raised her head slightly, and shouted at the dark place again!

As if in response to Zhao Ling'er's call, an inexplicable cold wind suddenly blew in the originally quiet cave!

"Roar~~!"

A deafening sound like the roar of a bull came from the darkness! The sound wave that came from the storm actually blew up all the dust on the ground!

"The Zhao family?"

A little dark purple lightning flashed from the darkness, and a slightly rough voice slowly came out of the darkness!

"Knock! knock!"

The ground trembled, as if it had been hammered by some heavy object!

"Click!

Countless tiny cracks spread out from the darkness, but when they came into contact with the glimmer of light reflected in the large array, in the blink of an eye, they returned to their original state!

"I really didn't expect that after so many years, there would still be someone who could find here!"

The rough voice came from far and near, and through the faint light reflected in the large array in the cave, it could be vaguely seen that in the darkness, there seemed to be a pair of huge wings swinging slightly!
