From the light curtain, you can see that rows of masonry longhouses are connected in a spiral shape from end to end, and one after another, the entire underground space is paved into a large swirling town.

The longhouses are separated by no corridors, and the different styles and colors clearly indicate that they were built separately rather than unified planning, as if someone had removed the side walls of the independent houses and connected them at the same time.

In the center of the town was a pitch-black plateau, which looked like a giant fountain 30 meters high, but now it was depleted, and only a statue with an indistinct face remained, and a black hole appeared on the side.

The undead don't need a house, and even the handful of nostalgic lich dwellings can't be of town-like proportions.

Could it be that the ancient human towns in the Northlands before the undead wreaked havoc gradually sank into the ground as the terrain changed?

But where is the dragon corpse from remote sensing, and where does the nutrients come from?

Where does the hole next to the fountain lead, could it be that there is a third level of underground space under this swirling village?

The scene in front of them overturned all previous speculations, and the four of them looked at each other, giving birth to a thousand feelings for a while.

"No matter, let's go down first, the sixth battle formation, pay attention to vigilance. ”

Because he had put down the floating sun furnace and the falcon detector before, the perspective of the light curtain in Allen's hand was very clear, and after taking a closer look, it didn't look like there was an ambush, so he directly issued an order.

The four of them entered the "shortcut" magic array in turn, and with a flash of light, they found themselves standing on a small dirt slope at the entrance of the whirlpool town, although the magic shield could filter harmful gases, but the nose was still filled with an unpleasant smell of decay. In front of me was a gray and dark red gravel path, hundreds of years had passed, not to mention weeds, not even mushrooms, only a few piles of wooden planks and bricks, apparently from the dilapidated longhouse on the side.

In a hundred years, the longhouses have not collapsed much, but the gray walls are worn and mottled, hanging weakly on the green bricks, and there is a sense of depression and old as far as the eye can see, and even a hint of cold chill, telling the endless resentment generated after the town has been shrouded in darkness for hundreds of years.

The glow of the floating solar stove makes this ghostly town clothed in a light mist like cicada wings, not only not bright, but more mysterious.

Alan looked closely at the height of the house, and it was less than three meters, a distance that would not hurt the team even if he stumbled.

"Don't take the path below, let's go straight to the ridge and we'll soon be in the center of town. ”

Roland opened his clairvoyant eye, beware of sneak attacks from the longhouse beneath his feet. ”

Although there was already a faint feeling in his heart that the Skeleton Master should have moved directly to the hole in the center of the town, he still couldn't take it lightly - the most important thing was that the Eagle Falcon Detector, which was only half a minute before and after the Skeleton Mage, had no trace of him at all, so there was a great chance that he would move inward in a circle from the longhouse.

At this moment, Shirley, who was the first to jump on the roof, suddenly let out an exclamation and flew upside down from the ridge.

Wang Zhen quickly stepped forward and grabbed Shirley's waist, and quickly put it down, and was about to jump on the roof to check, but just about to jump, Shirley suddenly grabbed his sleeve, "Don't go up!"

"Is there anything up there?" Allen's eyes never took off the light curtain in his hand, following the image from the falcon detector. Shirley just jumped up and then jumped down on her own, and was not intercepted.

"There seems to be something like a gravity circle carved on the roof, and there are so many of them that once you step on it, you get traction coming from all directions, and you lose your balance. And in my senses, all the roofs here have similar forensic carvings. Shirley shrugged.

"Gravity array?" The three of them were all shocked, this kind of magic array is extremely complex, often depicted in the manned cabin of high-speed warships and shuttles, using artificial gravity to offset the acceleration of the battleship, and the lowest level of gravity array is also above level six, and the ancient town can actually be carved on the roofs of all the dilapidated longhouses, is it not possible that the residents of this ancient town are all transcendental.

"No wonder the skeleton mage chose to move along the longhouse, so we'll go straight from the ground to the center of town, smashing all the walls that stand in our way. ”

This is in the territory of the undead in the Northland, and everyone has no idea of protecting the monuments, so they immediately wave the weapon in their hands and smash it like a wall.

"Boom ......"

With a puff of smoke and dust, the longhouse in front of him was blasted out of a gap five meters long and two meters wide.

"Let's go. ”

Wang Zhen was the first to step into the collapsed low wall.

When I entered, I found that there was no furniture or partition walls in the longhouse, but in the middle of the house stood a wooden pillar every five or six meters, which was only the thickness of a human thigh, but it was full of endless stretches as far as the eye could see.

Above the pillars are two intersecting beams, one end held up by the column like a cross, and the other firmly against the roof.

"It's strange, do the residents of this town, regardless of you and me, live in a "one-bedroom"?" Wang Zhen couldn't help but slander in his heart.

"According to this structure, entering from the first door at the entrance of the village, you should be able to go all the way to the center of the town, and the longhouse connected from end to end is no different from the corridor outside, except with a cover. The boy muttered to himself.

Lucy said, "Hee-hee, if you move the lid on the top and cover it on the path outside the door, the path will become a longhouse, and the longhouse will turn into a path, it's a really weird structure." ”

Move the lid down?

Speaking of this, the four of them were stunned.

It's clearly underground and it won't rain, and there is no need for privacy in this kind of paving, so why should the house be covered?

If you want to say that the vicissitudes of the sea and the terrain are sinking, then this not a sturdy longhouse will collapse most of it, and it will never be as old as it is now.

"Hmm, I have an immature idea - do you think this is an underground fortress of ancient humans, and these longhouses without partitions are only used to transport troops and materials, and then the undead used some means to sink into the ground, and they are about to bury the strong people of the human race and rush out to fight with the undead above, and finally triggered a second magic attack, sinking the ancient battlefield into the ground. Lucy said as she tore down a section of the wall.

The three people on the march were silent for a long time, and Wang Zhen took the lead in saying, "Let's assume that the undead clan has some kind of weird magic that does not destroy the building but only sinks it, but the human fortress will never build the house like this to transport supplies, obviously the distance in a straight line is only half a minute, and it takes more than three hours to transport the cliff from this longhouse, which commander dares to build the fortress like this, I am afraid that the moment he puts forward his idea, he will be killed as a spy by his colleagues." ”
