In the closed dome "yurt", when Ying Xingtian was about to use his strength to destroy the surrounding curved brick wall, he heard Ou Haichao not far away say that he had found the location of the ventilation formation, and quickly withdrew his palm and took a few steps to cross in front of the latter: "Where?"

The old man with the silkworm eyebrows was full of pride, and stroked his palm and knocked on a certain place on the ground: "The predecessors who built this 'yurt' are very ingenious, not only the Jingdao family formation should also have a little bit of dabbling in the now lost Momen skills. If it weren't for the old way, I had seen a similar situation in the ruins of the Han and Tang Dynasties, maybe I would have been deceived by him. ”

Ying Xingtian's eyes swept with the tapping of his palm, and soon he saw more than a dozen fine holes on the ground, but he couldn't believe it: "Only these holes can meet the ventilation needs of such a large space?"

"This is the Eye of the Formation, and the same holes are all over the walls and domes. Ou Haichao continued to smile proudly, and then stretched out his hand to smash the bricks and stones on the ground with a golden sword-shaped order: "Look, the core formation pattern is here." ”

At the breach of the masonry, on top of a swirling black formation, there was indeed a shining cyan turquoise gemstone.

"As long as there are holes, there should be a corridor to the outside world. Ying Xingtian nodded slightly, beckoning all the remaining members of the Ruins Exploration Department to come over, and then squatted down and slammed it on the ground.

Under the unparalleled strength of the top martial arts masters, the hard ground instantly broke open a big hole as if it was made of paper, and the smashed bricks and stones turned into powder, and fell down the big hole in a hurry.

"It's so thick! at least half a meter!" Ou Haichao took the first step to put away the cyan turquoise, and then looked down, and then turned his head to look at Ying Xingtian with a slightly shocked look - the green brick was completely broken under such an understatement punch after half a meter. If this kind of punch hits you, even if you hit it full of defensive orders, I'm afraid you will be injured instantly.

"Win boss, when you and Zhu Huang were fighting just now...... Hidden power?"

The latter's handsome face was unwavering, and he didn't even look at Ou Haichao, but only took out an arm-thick "flashlight" from his bag and shone it into the hollow below: "It's not a battle of life and death, why go all out." ”

Ou Haichao was silent, and was silent for a long time before following him to look down.

"Damn, why is it so bright?" Before he could see the situation clearly, his eyes were pierced by the light of the flashlight in Ying Xingtian's hand, and he felt as if he was looking directly at a small sun, and he almost burst into tears: "What kind of flashlight is this?"

When he looked up from his eyes, he found that except for himself, Ying Xingtian and the eight members of the Qianlong Yuan had all put on Fu sunglasses at some point, and they were all turning their heads to look at this "Yan Dao" Grandmaster—they couldn't see their eyes under the black lenses, but the expressions on their faces were all like idiots.

"Eighty-three thousand lumens of hand-held searchlights, haven't you been equipped with 'Yandao'?"

Ou Haichao knows that "lumens" is a unit of brightness...... But I never thought that the lumens of a flashlight could be calculated in "10,000", and it took a long time to rub my eyes before I took Fu Sunglasses from the hand of a member of Qianlong Yuan next to me: "How did I know that your expedition equipment is so perverted, even the little sun is carried with you." ”

This time, Ying Xingtian didn't pay attention to him again, only looked down for a moment, and then waved his hands together, expanding the brick and stone breach enough for one person to pass: "Keep up, grab the surrounding wall and fall down carefully." ”

Beneath the "yurt"-like dome building, there is a bottomless straight passage like a deep black well, and even if it is illuminated by the strong light of the searchlight flashlight in the former's hand, it is still as dark as ink as far as the eye can see.

"Hey, is there something there?"

One of them suddenly pointed to a spot where the flashlight was shining: "There, is it a figure?"

Everyone was nervous as they looked in the direction he was pointing.

It's just that when I look closely, I find that it is just a few of their vague figures, the reflection on the glorious blue masonry somewhere.

The person who spoke scratched his head and smiled: "I'm sorry, I read it wrong." ”

"It's going down like this, at least a dozen kilometers. One of the members of the Ruins Exploration Department frowned: "If this is still the case underneath, I'm afraid it will all go up to the mantle layer." Even with the assistance of Qing Dynasty cultivators, it is absolutely impossible to build this kind of masonry road...... Be careful, my lord. ”

When his words fell, Ying Xingtian's whole person had already reached inside like a deep well.

Then, a miraculous situation appeared in front of the remaining nine people at the same time.

——Winning Xingtian's body in the passage shook slightly, and his feet stood firmly on one of the cyan brick walls, showing a vertical angle to the yurt building above, and he did not fall as he imagined.

Not only were the nine people above stunned, but even Ying Xingtian himself was slightly surprised in his eyes, and looked up at the people who were "perpendicular" to him: "I am here, it seems that the place where my feet are stepped on is the ground...... Come down and try it. ”

A few seconds later, the group drilled into the "deep well" passage inside the hole.

Then everyone asked, standing on the "ground", their eyes were also full of disbelief.

The ground of the yurt building above the head is actually a vertical relationship with the ground in the passage here!

So which side is the real "down"?

"Gravity, it's gravity that changes. After a moment of silence, one of the members of the Hidden Dragon Abyss finally determined the direction: "The direction of gravity in our position is completely different from the direction of gravity in the building above. ”

The rest of the people nodded their heads in agreement with the only logical judgment.

But the question is, what kind of magical power can make such a miracle that violates the normal rules of physics appear in the "former Qing ancestral land" buried deep underground?

Even as cultivators, they had never heard of anything like this.

Ying Xingtian's gaze turned to Ou Haichao, and the latter had a ghostly expression on his face: "I don't understand, even if the Daomen Formation is the most magical spatial teleportation array, it can't change the direction of gravity in the universe." ”

The former looked back at the yurt space above his head and took a deep breath: "Look ahead, the situation here is no less weird than Shanglinhu Ancient Kiln City, everyone be careful." ”

Ou Haichao, who was the only one who had seen the ancient kiln city of Shanglin Lake, was slightly frightened, and couldn't help but get nervous.

But don't do it again like last time, and make a life of nine deaths.

……

……

"There is light. ”

"The air is the same as here. ”

"Uh, sorry. ”

When the brick wall was finally smashed, Ji Yiming and Yu Zhenzhen leaned over at the same time to look, and accidentally squeezed together face to face and quickly separated. The former turned slightly red and quickly apologized, but the latter pursed his lips and smiled: "Shy again? You look like this, could it be that you were chased by Jiang Zhiyou in the first place?"

"There's a lot of space in there, but it looks like a semicircle coming horizontally. Ji Yiming's expression was embarrassed, and he didn't squint at the slightly transparent area behind the hole: "It's as empty as here, I don't see anything." ”

Yu Zhenzhen glanced at him again: "It's not interesting, it must be Jiang Zhiyu who is shameless and chasing you." ”

“……”

"Let's go over and take a look, although there doesn't seem to be any exit over there, at least it's more spacious than here. ”

Ji Yiming nodded and took a few steps back, and Xiao Yang, a huge Gu snake behind him, quickly jumped up, shook his head and slammed it several times on the breach that was smashed open by Yu Zhenzhen.

The powerful and huge power of the Grandmaster Realm Gu Snake was naturally more terrifying than that of the latter's top-grade martial artist. With just a few simple impacts, the breach of more than ten centimeters directly turned into a passage with a diameter of more than two meters, and the wide space in front of them finally completely appeared in front of the two.

Ji Yiming visually measured it, and the height difference was about five meters. There are several permanent lamps on the walls of the semicircular space, which are emitting a faint yellow light, the only strange thing is through the gap in the stone lampshade...... The direction of the burning flame seems to be slightly strange: "The light is horizontal, why is the fire also burning horizontally?"

After confirming that the space ahead was safe and not dangerous, the two of them jumped directly through the passage and jumped off the ground several meters high as they spoke.

Then, the same confused expressions as Ying Xingtian and the others appeared on their faces.

"What...... Situation?"

"Direction, direction flipped. ”

Yu Zhenzhen looked up at the tunnel on the dome wall where the two people came over, and although she quickly made a judgment, she also didn't understand the contrast: "This side is horizontal, and that side is vertical." The two spaces are perpendicular to each other...... No, it seems that the direction of gravity on both sides is different. ”

As soon as she said it, Ji Yiming also quickly noticed this: "Can the formation do this level?"

"Theoretically, no, in practice...... I've never seen or heard of it. ”

The two of them were full of doubts here, and after the Gu snake Xiao Yang next to him entered this dome-shaped arc-shaped building, he quickly swam around, and his huge eyes like copper bells showed a look of doubt.

After circling for a while, it took the initiative to rush to Ji Yiming's side and hit the latter with its big head, and the crimson snake letter spit out, wrapped around his arm, and dragged it towards a corner of the hall.

"Discovery?"

Xiao Yang opened his mouth and wrapped the snake letter around Ji Yiming's arm, nodding his head very reluctantly.

The two of them followed the cute Grandmaster Realm "Yin Evil Anode Snake" through the entire hall and walked to one of the corners, and soon under the former's shaking of his head, he saw a palm-sized disc-shaped bulge embedded in the wall.

The disc is staggered with black fine lines, and in the center is a pure blue turquoise gemstone of no small quality.

A slight but steady fluctuation of the formation was slowly escaping from the turquoise gem.

This thing......

Ji Yiming and Yu Zhenzhen frowned at the same time, and turned their heads to look at each other at the same time: "Array?"

——In the buildings under the "Former Qing Ancestral Land" more than 300 years ago, why did the small array that was researched by the scientific research team led by Yan Siguang appear in the recent year?

"This material is wood, which is not the same as your Hidden Dragon Abyss silver. Ji Yiming's heart moved slightly, and he took out the silver array plate given by Ying Xingtian and brought it to the side to compare: "But the size is very close, and the upper array pattern is also engraved with metal edges, as for the metal material...... It may also be a little different. ”

"Is this miniature formation of the array disc really the first to be created by Yan Siguang and has never been invented before?"

"As far as I know, this is true, and it is only after we watched Lao Yan go from conception and experimentation to withdraw from the new version step by step to gradually improve it to the way it is now. Yu Zhenzhen's fingers pressed down on the wooden array plate, and he didn't dare to destroy it forcefully: "And in the history of the cultivator world, there has never been a similar record. ”

"Maybe the great wisdom will have the same aura and creation, don't worry about this for now. Ji Yiming waved his hand and did not continue to dwell on this matter: "Can you see what the effect of this array is?"

Before he could speak, Yu Zhenzhen had already carefully studied the carved patterns on the wooden array, and his eyes showed a look of thought.
