The surroundings were covered with a light yellow fighting spirit, and the sword in both hands slashed out horizontally with an invincible momentum.

The thick metal security door is more than ten centimeters thick, but like butter stabbed by a hot knife, it is silently cut open, neatly and without any hindrance to the giant sword.

One horizontal and one vertical, huge cross-shaped cutouts appeared on the safety door, and the fluorescence of the crystal energy lamp was revealed through the cutout, and the space outside the door could be seen.

"Nee." Makajren and Mobak couldn't help but take a breath. Although it was not the first time I saw the female swordsman's attack power, every time I saw it, I felt a chill in my neck, as if a giant sword could be chopped up at any time.

Indeed, Saff's attack power was amazing. The light-armored female swordsman almost abandoned all defense abilities and focused on weapon attacks, which led to her attack power being abnormally high. Even heavy-armored warriors like Mobak who specialize in defense dare not take her attacks frequently. However, the female swordsman's personality completely concealed her strength. Without anyone seen with his own eyes, it is hard to imagine the horror of a shy girl when she launched an assault.

Fortunately, Saff was always shy and shy, and did not receive the orders of Shure, and rarely attacked actively. The problem was... the halfling touched her neck, and shouted, I hope she would not enter another state.

"Dang, dang", the metal landed on the ground.

The giant sword slashed four times more obliquely. A huge diamond-shaped gap appeared on the metal door, and a triangular metal block hit the ground, making the ground buzzing sound.

Pulling his head out, Mobak's body froze at the diamond hole. It was not until the halfling kicked him in the back that the dwarf reacted and swallowed heavily: "You guys are mentally prepared, don't be surprised, there is something here..."

"Idiot, do you think anyone has never seen the world like you? Our halflings are all over the world, and I have never seen any scenes. Do you know whether the king capital of the Winged Humans is much taller than here. I am on it and... Oh, Wind Sailo is on it, the underground city." The halfling who will never forget to brag finally couldn't speak this time.

After following the end of the team, Shuer was the last to drill out of the metal hole and finally saw a scene that made his teammates speechless.

Walk out of the door and stand on an empty platform. The surface of the platform is made of alloy. Although it looks monotonous, it is clean and refreshing enough.

Looking up, the abdomen is above 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 fluorite emitting green fluorescence distributed scattered. The glimmer of light shines through the glass, covering everything inside the dome with a green coat.

Of course, these are not enough to make the knowledgeable shadow-seekers lose their composure. What really shocks them is not the top but the bottom.

The entrance platform can be regarded as the highest building in this area. Not far from above is the dome. Walk to the edge of the platform and look down, a scroll unfolds in front of everyone.

Just as Marca Jaylen was amazed, this is not a simple ruin, but a huge underground city.

The rocks on the mountain were dug out a hemispherical cavity, with a radius of at least two kilometers, and the entire city was 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 middle, and the top platform is built around the stone pillar. When you come in, the last hall is located inside the stone pillar, and the exit is open at the edge of the stone pillar.

The remaining twelve are distributed scattered in different locations of the cave, which not only serves to support the dome, but also bears the weight of each floor of the underground city.

Yes, on each floor, this is not a flat city, but a three-dimensional one.

The underground cave is four hundred meters high and is divided into at least eight floors. Each floor is built with various buildings, and the floors are separated by hard glass and metal building materials. In many locations, through the transparent glass floor, you can even see the bottom rock 200 meters away.

The green fluorescence emitted by fluorite enveloped the entire underground city, causing the city to fall into a haze of green, like a secret realm in a fairy tale. The city is quiet, as if time had already stopped and everything fell into a deep sleep.

The hazy city, the dark light, the seven people looked at everything in front of them, and even forgot to guard and guard, or even where they were.

"We really... picked up the treasure." Xiuer let out a long sigh, his voice as if he was afraid of waking up the sleeping city. "Stop looking, think about it, there are still twelve days for this projection in another world. Even if you leave early for safety, there are still ten days to explore this city. What do you think we can gain? Haha, this time it is really..."

"It's really that simple?" Mia's light green skin looked particularly weird under the green fluorescence.

"Of course it's not that simple. If you want to get rich, you must first survive." Xiuer looked at the entrance where everyone came in meaningfully, raised his voice and said, "Now explore the state and eliminate all distractions."

"Time is not urgent, so don't worry about plundering items. Get ready for the retreat first and take other things slowly."

"The first step is to find a place for energy supply and restore urban energy supply, which is the basis for everything. Although the fluorescence is beautiful, I need a real daily light source."

"The second step is to find the point of departure. There is such a large space in the city, which can basically be confirmed 100%. The point of departure is in this mountain belly. Find it and ensure that we can leave at any time and then search for wealth."

"It's the first time I've discovered a ruin with such great potential. This is an opportunity, and it may not be a crisis. Whether you will return home with a full load or be buried here depends on everyone's attitude and psychology."

"Maca Jaylen, tell the time."

"I understand." The half-ling suppressed the excitement in his heart, "Ten at 10 o'clock."

"Now, it's ten o'clock in the morning the next day, and camping time tonight, at 5 o'clock in the afternoon, that is, exactly six hours of exploration time, the goal is to restore the city's energy to the light again today. Are there any doubts?"

"No."

"Very good, switch to regional exploration formation, start moving, targeting the lowest level."

No one asked why he chose the lowest level. Shuer never issued orders and did not explain his thoughts. Everyone was used to it, just follow the orders. No one expected that he would explain this time. Perhaps not anyone had expected that at least a certain tree spirit would smile like a flower.

"Energy will explode if you are not careful. No matter what energy is used to supply energy to the city, the most important thing is to stabilize the equipment. Of course, the most stable thing is to be down-to-earth. If it were me, I would definitely choose to install functional equipment at the bottom. I am just watching me for what I do? Can I shine or heat up? Don't talk nonsense, and I will work for me."

"Shuh, a fool with different hearts." The teammates made a contemptuous gesture, no longer paying attention to the fool who tried to make changes, and devoted themselves to the exploration.

It is no simple matter to explore a three-dimensional city, especially when there is only a small light.

The first question is how to proceed.

There is a set of mechanical equipment at the edge of the platform. The most experienced elves once saw something similar in a projection in a different world. It is said to be an automatic lift that can move between floors. However, since it is an automatic device, it must be driven by energy. Now that the energy supply is lost, the equipment will certainly be impossible to use again.

As for destroying the bottom of the elevator and jumping down the track directly, at a height of 400 meters, everyone is not crazy yet and does not intend to make such an attempt.

Fortunately, in an inconspicuous corner, Macajren discovered an ordinary staircase, and the metal staircase stretched downwards around the giant stone pillars, and was curved and could not see the end.

The steps on the stone pillar are very special. The height difference between each step is about two meters, which is higher than everyone's height. If you are an ordinary person, you may not be able to use it normally. Fortunately, all the combat pros are present, so it is not a problem to jump up and down on the two-meter-high steps, but it is a bit troublesome. However, if you think about the race of the city builders carefully, it is understandable that the steps are higher.

Jump down the steps one by one, and the team goes deeper and deeper. Every time you pass a floor, you have to endure the urge to explore the floor immediately.

Fortunately, although you cannot explore carefully, you can still observe it from afar when passing through each floor to satisfy your curiosity. Otherwise, these shadow chasers driven by the desire to explore may be driven crazy.

Each floor of a conical city has its own characteristics. Generally speaking, the more upward the floor, the more sparse the buildings, the more beautiful the environment. You can even vaguely see the remains of facilities such as artificial pools on the top floor. There are also many exquisite statues on the penultimate floor. Most of the rooms are made of tinted hard glass, which is opaque, but they are quite beautiful in visual sense.

However, after passing the fourth floor, the buildings became more and more dense and the vacant land became less and less. All the materials of the building were replaced with metal, which was stiff and cold and lifeless.

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

The architectural style is very different from the world of Pavatiga. The buildings here are all semispherical, with smooth and round metal walls and no edges are visible.

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

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

Finally, he was down to earth, and the Shadow Chaser secretly exclaimed. He went down, although he was carrying the steps, but he had no room for maneuver in the air. The Shadow Chaser must always be on guard, fearing that some strange creatures would rush out from the shadows of the surrounding buildings to launch an attack.

"Stay safely and start searching for targets."
