Inside the huge fortress is a strange three-dimensional city!

The height of this fortress, Tian Xian speculated that its interior should be layered, but when he really saw the interior, Tian Xian knew that he was wrong.

And it couldn't be more wrong.

Yaoyao's eyes widened, there would never be such a city on the human continent, and even Yaoyao never thought that she would see such a city.

The city is protected from the inside by a fortress-like façade, straight up and down!

Huge pillar buildings stand densely on the ground on the ground floor, reaching to the sky!

Tian Xian and Yaoyao and the returning command officials entered the city through a huge passageway, walking on a street that was not wide, and this street was separated by countless buildings of all sizes, almost up to the top of the city.

Above, the light of the sky was faintly visible, and these huge vertical lights were not dazzling, but only illuminated the places around them, and Tian Xian could even distinguish the stars high in the sky with his amazing eyesight.

The appearance of these tall buildings is not uniform, there are square and round, some are relatively neat, the top and bottom are consistent, and they seem to be the whole building, and some are crooked, and even seem to be slowly connected later, and even more are thin and thick at the bottom, as if they are miraculously towering there like stalactites hanging down.

There are few bridges and passages in the sky, and at such an altitude, you can clearly see the stars in the sky, and there is almost no shelter in the air.

Tianxian and Yaoyao could see it clearly, and people were flying in the air......

In this huge city, which goes straight up and down, people fly through the gaps in the buildings, and it is effortless.

Tian Xian had already seen that the commander who had returned with him in front of him was slowly rising into the air.

Is it so easy to fly?

If you want to fly, you can naturally do it easily now, and Yaoyao is the same, but after all, this is an act that consumes strength, and it will not be as easy as walking and running.

But all the people I saw in mid-air were flying freely with ease, and some of them even flew by at a rapid pace, chatting with their companions, and even eating.

It's like walking.

"Brother Xian......" Yaoyao walked up from behind, and now she didn't care that she might be seen by acquaintances, Yaoyao found that all the commanders had gone to the front positions and lifted off one after another, flying to different places, without exception.

If Tianxian and Yaoyao don't do it, then they will immediately become the focus, and if they are noticed a little, their identities may be exposed.

If you want to fly as easily as these people, you will probably have to use demonic power, and then your identity will be ruined.

"Don't worry. Tian Xian simply held Yaoyao's hand directly, "It's just a fly, it's okay." ”

Tianxian released his energy tentacles and quickly detected the surrounding situation, but before he could gain anything, he found that the eyes of the people around him suddenly became strange.

There are countless commanders who came back with Tianxian and Yaoyao, after all, the number of human slaves outside the fortress is too much, and the number of commanders needed is also very amazing, if not eight hundred, but also one thousand.

But all the way was peaceful, no one came to disturb Tianxian and Yaoyao, and no one looked at it more, but now Tianxian suddenly found that these guys would focus on themselves and Yaoyao intentionally or unintentionally.

Is there something wrong?

Tianxian became vigilant, Yaoyao also felt this gaze, and couldn't help but move closer to Tianxian's side, ready to fight at any time.

The energy tentacles blended into the surrounding energy fluctuations, and Tian Xian was on guard while quickly probing the surrounding situation, especially the places in front of the commander who flew into the air.

Suddenly, Tianxian was slightly stunned.

A huge energy body blocked Tian Xian's energy search, and the energy tentacles that stretched out were almost destroyed, and Tian Xian could detect the specific situation ahead of him after carefully retreating and cautiously before and after.

"A huge flow of energy......" Tianxian whispered to Yaoyao.

"What?" Yaoyao didn't understand, and ...... What is the huge flow of energy?

Tian Xian himself didn't understand very well, because in the feedback of the energy tentacles, there was a huge, enchantment-like energy flow from the ground to the sky in front of him, but he couldn't feel the fluctuations emitted by this huge energy flow here, if it weren't for the precise exploration ability of the energy tentacles, Tian Xian couldn't believe it.

The street was not wide, it could even be said to be a passage between crowded buildings, but there seemed to be an open road leading in all directions, and that was where the commanders took off.

The energy tentacles fed back precise energy fluctuations, and Tian Xian transmitted this energy fluctuation to Yaoyao, "Remember this energy fluctuation, they seem to rely on this energy flow to fly upwards. ”

Yaoyao nodded, slightly nervous in her heart.

Soon Tianxian and Yaoyao came to the first intersection of this street, which is also the place where the commander took off, and in front of Tianxian can already see the roads extending in all directions, but it seems that these streets are crooked and very narrow, and the buildings on the ground floor look very old and dilapidated.

And...... There was no one, and although there were many people flying in the sky, there was no one on the street on the ground, the street was empty, and the buildings on both sides were basically no lights, and occasionally some of them were bright, all of which were tattered and could not see the brand of the shop.

Glancing at the foot, at this street junction, a clear boundary appeared, the road on the side of Tianxian was a black brick road, and the front was a white stone paving, and there was a thin gap between the two.

"Let's go. ”

Tianxian pulled Yaoyao and stepped on this line first.

Stepping on the white stone pavement, Tianxian instantly had a feeling of being overpowered, and a surging but soft force rose from under his feet, like a soft cloud, making himself a little unsteady on his feet.

At the same time, Tianxian felt that he was wrapped in a thick but light energy, and the whole person became a little lighter.

At such a close distance, such a huge flow of energy would not leak a single breath, which was simply amazing!

The energy tentacles quickly merged into this powerful energy flow, and Tian Xian had a feeling that he was going to carry out energy drifting, so he quickly suppressed his own energy fluctuations, stood firmly on the ground with his feet, and pulled Yaoyao in at the same time.

Yaoyao was also shocked as soon as she stepped in, opening her mouth slightly, she didn't expect that the huge energy that was close at hand was already in front of her just now, but she couldn't feel it.

"Adjust your strength and follow the flow of energy to rise. Tianxian said to Yaoyao quickly.

Yaoyao is already doing it, just now Tianxian has passed on the fluctuation of this huge energy flow, which is not new to Yaoyao, but she has never tried to slowly float in such a thick energy flow, and it takes a little time to prepare.

This short period of time is extremely tense for Tianxian and Yaoyao, and Yaoyao herself is living like a year.

There are strange commanders all around, and if they are found to be intruders from the outside world, judging by the tightness of the security of this fortress-like city, it is possible for these people to kill the intruders directly.

"Hey, you two!" Just as Yaoyao was about to float up, a voice suddenly came from behind her.

Tianxian and Yaoyao's hearts were slightly nervous, and when they looked back, they saw that it was a young man who was not very old and full of doubts, he looked at Tianxian and Yaoyao, frowning, as if he had seen these two people for the first time.

Something is wrong!

As soon as he saw the young man's expression, Tian Xian knew that things were not good, so he clenched Yaoyao's hand, pulled her directly behind him, and asked in a low voice, "Is there something wrong?"

The ancient gods of Tianxian didn't speak very well, so they spoke quickly and briefly to hide the unnaturalness of their voices.

The young man was stunned for a moment, as if he was a little surprised, then looked at Tianxian, and then at Yaoyao, "I mean...... How do you two ......?"

At this point, suddenly the ground shook violently, and then a huge explosion came from high in the sky, and the fierce sonic boom pressed straight to the ground, and the air roared.

The commanders all changed color and shouted and accelerated into the air!

The young man stood firm, his face changed slightly, and he looked at the sky and said hatefully: "It's actually here again, it's really haunting this time!"

Looking down at Tianxian and Yaoyao, the young man nodded, "Let's see you later!"

With that, he rushed into the white masonry ground, jumped into the air, and disappeared between the buildings in the blink of an eye.

Tianxian and Yaoyao both breathed a sigh of relief, and glanced at each other, with a wry smile and happiness in their eyes.

The sound of vibrations and explosions continued to come, and the commanders who had just retreated from outside shouted and flew into the air, and no one paid attention to Tianxian and Yaoyao anymore.

Tian Xian and Yaoyao, who had a chance to breathe, quickly calmed down, familiar with the fluctuations of energy flow, and the two flew into the air together, merging into the ranks of those commanders, without the slightest abnormality.

There was the sound and fluctuation of the energy of the battle in the sky, and the commanders around Tian Xian and Yaoyao were all angry, and they rushed into the air quickly, as if they were going to support the battle.

Tianxian and Yaoyao were slightly slower than them, and their attention was not on the battle at high altitude.

At this time, Tianxian and Yaoyao were both shocked by the strangeness of the city.

The fortress walls outside this strange city envelop the city like a giant shell, and this huge city resembles a sprawling, towering forest, with buildings reaching into the sky like giant trees.

Tianxian and Yaoyao slowly rose into the air, occasionally deviating from some directions, gradually separating from those commanders, entering the rest of the city, and quickly finding a hidden place to hide their figures.

Presented in front of Tianxian and Yaoyao is a huge three-dimensional city, countless towering giant tree-like buildings from the ground to the sky, complete and integrated, intermittently connected, small or huge, all make full use of every inch of space in this huge fortress.

At the same time, these buildings are naturally separated from each other by straight up and down space streets, some of which are extremely narrow enough to accommodate one person to pass through, while others are much wider, and it is no problem to run several large carriages side by side.

Tianxian and Yaoyao hid in the shadow of a building, looking at this strange city that leads to heaven and earth, and the people flying around in it, they were all amazed for a while.

Looking at it, Tianxian suddenly has a feeling of going to the future world, this kind of deep city, it seems that I have seen it in some science fiction movies, but I didn't expect to see it in this world full of magical power today.

The tremors and loud noises above the city continued, and it seemed that there was a fierce battle, but Tian Xian found that the people in the city were not very nervous, except for some people who were hurrying to and fro, most of them seemed to be unconcerned, and they were completely accustomed to it.

"This place is really weird...... Yaoyao looked around curiously, "and it's many times bigger than Fire Leaf City." ”

Tian Xian thought to himself that this is not only many times, the area of this place is much larger than that of Fire Leaf City, and this in-depth urban design from top to bottom is probably a hundred times more than the sum of population and buildings than Fire Leaf City.

If this city were spread out like a human city, it would be many times larger than any city on the human continent.

"Where are we going now, looking for something to eat?" Hiding in this huge city, Yaoyao began to become excited again.

Tianxian looked at the sky, "We are safe now, and it seems that it is difficult for ordinary people here to find us, but ...... I'm curious to know what the hell is going on up there?"

"It sounds like it's fighting, I don't know who I'm fighting. ”

Tianxian frowned, "I faintly heard the sound of something roaring, it seemed that there was some monster." ”

"Let's take a look!" Yaoyao clenched her little fists with excitement on her face, "But I can't be discovered, I was really scared to death just now." ”

"Be careful, we're not familiar with everything here, don't reveal your identity, and protect your identity no matter what. ”

"Got it, got it! Let's go!"

Tianxian and Yaoyao did not return to the ranks of those commanders, because Tianxian and Yaoyao had no idea what these people were going to do, and if they wanted to join the battle directly, then they would be cannon fodder for nothing.

And to put it bluntly, I don't know if these commanders will meet anyone when they get there, or if they have something to do, if they don't do well, their identities will be exposed.

After taking off the commander's clothes, Tianxian and Yaoyao casually took a few pieces of clothes outside the flashing window, put them on their bodies and touched them into the air.

The battle seemed to be unusually fierce, and as it approached the heights, the sound of energy colliding was deafening.

"It's a dragon!"

Tian Xian finally heard the faint roar clearly.
