Wrapped in a pale yellow fighting aura, the two-handed sword slashed out horizontally with an indestructible momentum.

The heavy metal security door was more than ten centimeters thick, but it was cut silently like butter stabbed by a hot knife, crisp and neat, without bringing a sense of obstruction to the giant sword.

One horizontal, one vertical, a huge cross-shaped incision appeared on the security door, and the fluorescence of the crystal energy lamp penetrated through the incision, and the space outside the door could already be seen.

"Shhh Macageren and Mobuck couldn't help but take a breath of cold air, although it was not the first time they had seen the attack power of a female swordsman, but every time they saw it, they would feel a chill in their necks, as if the giant sword would cut at any time.

Indeed, Saf's attack power is really amazing, and the light-armored female swordsman has almost abandoned all defensive abilities and focused on weapon attacks, which has caused her attack power to be abnormally high, and even a heavily armored warrior like Mobuck, who specializes in defense, does not dare to take her attacks frequently. However, the character of the female swordsman completely obscures her strength, and without anyone who has seen it with her own eyes, it is difficult to imagine the horror when the shy girl launches a surprise attack.

Fortunately, Saf is always shy and timid, and does not get orders from Shuer, and rarely takes the initiative to attack, the problem is ...... The halfling touched his neck and whew, hoping she wouldn't enter another state.

"When the long, when the long", the metal fell to the ground.

The giant sword slashed diagonally four more times, and a huge diamond-shaped gap appeared on the metal door, and the triangular metal block smashed into the ground, causing the ground to hum with a muffled sound.

Poking his head out, Mobuck's body froze at the diamond-shaped hole, and it wasn't until the halfling kicked him in the back that the dwarf reacted and swallowed heavily: "Be mentally prepared, don't be surprised, it's a bit ...... here"

"Idiot, do you think that no one has never seen the world like you? We halflings have footprints all over the world, and we haven't seen any scenes, and the king of the winged human race, the capital of the Floating City, knows it, it's not much higher than here, I'm on it and ...... Oh, the Wind Cello is above, the underground city. "The halfling, who never forgets to brag, is finally speechless this time.

After breaking off at the end of the group, Shul was the last to get out of the metal hole, and finally saw the scene that left his teammates speechless.

Stepping out of the gate, I stood on an empty platform made of alloy, which looked drab but clean enough.

Raise your head, above is the belly of the mountain, the transparent hard glass is close to the rocks inside the mountain to build a circular dome, on the inner wall of the mountain, there are a lot of fluorites that emit green fluorescence, the shimmer shines through the glass, and everything inside the dome is clothed in a green coat.

Of course, these are not enough to make the well-informed shadow chasers lose their temper, and what really shocks them is not from above but below.

The entrance platform is the tallest building in the area, and the dome is not far from it, and when you walk to the edge of the platform and look down, a picture scroll unfolds in front of everyone.

As Macajaren marveled, this is not a simple ruin, but a sprawling underground city.

A hemispherical cavity has been dug into the rocks of the mountain, with a radius of at least two kilometers, and the entire city is built on this cave.

Thirteen towering stone pillars run through the cave and support the dome of the cave. The thickest one is in the center, and the top platform is built around the stone pillar, and the last hall is located inside the stone pillar when you enter, and the exit is open at the edge of the stone pillar.

The remaining twelve are scattered in different parts of the cave, not only playing the role of lifting the dome, but also bearing the weight of each floor of the underground city.

Yes, the floors, this is not a flat city, but a three-dimensional one.

The underground cavern is four hundred meters high and is divided into at least eight levels, each of which houses a variety of buildings, separated by a mixture of hard glass and metal materials, and in many places, through the transparent glass floor, you can even look down to the bottom rock 200 meters away.

The green fluorescence emitted by fluorite envelops the entire underground city, plunging the city into a green haze, like a secret place in a fairy tale, the city is quiet, as if time has long stood still, and everything has fallen into a deep sleep.

The misty city, the glimmer of the morning light, the seven people looked at everything in front of them stupidly, and even forgot to guard and defend, and even forgot where they were.

"We really...... Found a treasure. Shure let out a long breath, his voice low as if he was afraid of waking up the sleeping city, "Don't look at it, think about it, there are still twelve days left in the safe time limit of this otherworldly projection, even if you leave early for the sake of insurance, there are ten days to explore the city, what do you think, what can we gain......?"

"Is it really that simple?" Mia's pale cyan skin looked particularly strange under the green fluorescence.

"Of course it's not that simple, if you want to get rich, you have to live. Shuer looked at the entrance where everyone came in meaningfully, and raised his voice, "Now explore the state and get rid of all distractions." ”

"Time is not pressing, so don't rush to loot items, prepare your way out first, and take your time with other things. ”

"The first step is to find a place for energy supply and restore the city's energy supply, which is the basis of everything. Fluorescence is beautiful, but I need a real everyday light source. ”

"The second step is to find the point of detachment, there is such a large space in the city, it is basically 100% certain that the point of detachment is in the belly of this mountain. Find it, make sure we can leave at any time, and then search for riches to our heart's content. ”

"After so many shadows, it is the first time to find a relic with such great potential, this is an opportunity, and it may not be a crisis, whether it is a full load in the end, or buried here, it depends on everyone's own attitude and psychology. ”

"Macajalen, tell the time. ”

"Understood. The halfling suppressed the excitement in his heart, "Ten o'clock." ”

"Now time, ten o'clock in the morning of the second day, and tonight's camp time, five o'clock in the afternoon, that is, sixteen o'clock. With nearly six hours of exploratory time, the goal is to bring the city's energy recovery back to the next day, is there any doubt about it?"

"Nope. ”

"Good, turn into an area exploration formation and start moving, target the lowest level. ”

No one asked the reason for choosing the lowest level, Shuer never just issued orders and did not explain his thoughts, everyone was used to it, just follow the orders. No one expected that this time he actually took the initiative to explain, maybe no one thought that at least a certain tree spirit smiled like a flower.

"Energy is something that can explode if you're not careful, and no matter what kind of energy is used to power the city, the stability of the equipment is the most important thing. The most stable is, of course, down-to-earth, and if it were me, I would definitely choose to install functional equipment at the bottom. Why are you stupid looking at me, can I shine or heat, less nonsense, give me work. ”

"Hey, stupid with different hearts. The teammates gestured with disdain, no longer bothered with the stupid guy trying to make a change, and threw themselves into the exploration.

Exploring a three-dimensional city is no easy task, especially with only a dim light.

The first question is how to go down.

There is a set of mechanical equipment on the edge of the platform, and the most experienced elven mage has seen something similar once in a certain otherworldly projection, which is said to be an automatic elevator that can move between floors, but since it is an automatic device, it must be powered by energy, and now that there is no energy supply, the equipment is of course impossible to use.

As for destroying the bottom of the elevator and jumping directly along the track, at a height of four hundred meters, everyone is not crazy and does not plan to make such an attempt.

Thankfully, in an inconspicuous corner, Macageren found the ordinary staircase, a metal staircase that stretched down around a massive stone pillar, curving with no end in sight.

The stairs on the stone pillars are very special, the height difference of each step is about two meters, which is higher than the height of all people, if it is an ordinary person, I am afraid that it will not be able to be used normally at all, fortunately, the people present are all combat professionals, and it is not a problem to jump up and down on the two-meter-high steps, but it is a little troublesome. Still, if you think about the ethnicity of the city builders, it's understandable that the steps are a little higher.

Jumping down the stairs one by one, the team gets deeper and deeper, and each floor they pass has to resist the urge to explore the floor right away.

Fortunately, although you can't explore carefully, you can still observe from afar when you pass through each floor to satisfy your curiosity, otherwise these shadow-chasers driven by the desire to explore will probably be driven crazy.

In general, the higher the floor, the more sparse the building, the more beautiful the environment, the top floor can even vaguely see the remains of facilities such as artificial pools, the penultimate floor also has many exquisite statues, most of the rooms are made of colored hard glass, opaque, but visually quite beautiful.

However, after the fourth floor, the buildings became denser and denser, and the open space became less and less, and all the materials of the building were replaced with metal, which was stiff and cold, and lifeless.

The floors are lowered step by step, and when everyone crosses the second floor and looks down from a height of more than 30 meters, they see a large dense complex of buildings.

The architectural style is very different from that of the Pavatiga world, and the buildings here are hemispherical, with smooth and rounded metal walls, and there is no edge or corner in sight.

Under the faint fluorescence, a large number of metal houses were hazy and piled together, and between the buildings, the winding roads stretched like a spider web, connecting the entire floor.

The road is also made of transparent glass, so stepping on it is like stepping on it in mid-air, which makes people feel scared, but if you get used to it, it will have a different flavor.

Finally down-to-earth, the shadowchasers sighed to themselves. All the way down, although there are stairs to carry it, there is no room for maneuver in mid-air, and the shadow chasers must always be on full alert, lest some strange creatures rush out of the shadows of the surrounding buildings to attack.

"Landed safely and began to search for the target. ”

Looking at the cobweb-like and intricate paths around him, Shul couldn't help but sigh softly.
