In the seemingly endless narrow passage, the ten people of Yingxingtian could only line up in a long line to move forward in turn.

After traveling extremely fast for more than ten minutes, it is estimated that it has advanced at least twenty kilometers or so, but the faint light source in front of it still looks out of reach. Ying Xingtian stopped and only hesitated for a moment, and without asking for the opinions of everyone behind him, he casually slammed his fist directly into the blue brick wall on his side.

The roar exploded with an entire mountain rock and a crater more than half a meter in diameter, and this time there was no second space behind the green bricks. Ying Xingtian's expression did not stop as usual, and continued to walk forward with the nine people behind him.

After a few more minutes of walking, he reached out and tapped the side wall several times before finally hearing the familiar echo of the hollow.

Still unpretentious, he punched out casually, and the two-meter-diameter passage at the gravel splash was successfully lined in front of everyone - behind the passage, a horizontal "yurt" building was impressively visible.

Sure enough, about twenty-five kilometers or so, there was a dome connected to the passage. Ying Xingtian turned over and entered, and after a while the direction was reversed, he stood on the ground in the center of the "yurt".

The remaining nine mermaids rushed in, and the eight members of the Ruins Exploration Department quickly probed around: "It's not the same as just now. ”

Ying Xingtian nodded slightly, and turned to Ou Haichao: "Find the ventilation formation, whether there is only one passage corresponding to each dome building." When I smashed the masonry just now, I didn't sense the fluctuation of the formation arranged in the middle. ”

The Lying Silkworm Mei Daoist was familiar with the road, and after playing a few cyan "crape myrtle swords" in various directions, he quickly found the location of the formation eye of the ventilation formation: "Here." ”

Ying Xingtian half-squatted down and punched the ground without hesitation, and at the same time, more than two meters of hollow was broken, and a second bottomless narrow road appeared below.

This time, he didn't enter it directly, but stood in place and looked around at the other nine people, his face was slightly solemn: "In addition to the gravitational force being changed, the 'former Qing Ancestral Land' here is still a very complicated labyrinth. Unless some of these key prohibitions are broken, we may not be able to find the exact location of the new corridors and domes that we continue to break down the walls to find - we should still be walking around the periphery by now, far from the true 'Ancestral Land' area. ”

Not only him, but the remaining eight members of the "Ruins Exploration Department" of Qianlong Yuan and Ou Haichao, the only outsider, also showed a solemn look on their faces. Everyone present was not a beginner who had experienced the ruins for the first time, and they knew very well that the most important thing when exploring the ruins of cultivators was not all kinds of dangers—after all, there were top martial arts masters like Ying Xingtian in the team, but it was this kind of "maze" that confused the senses and direction that was the most troublesome.

Fortunately for a short time, if they were trapped in countless passages and domes underground for a long time, they would not even need to encounter any enemies, they would only die of thirst and starvation.

Although a practitioner has a vitality beyond ordinary people, his essence is ...... The same is true for humans who need to breathe and eat.

"If only Boss Yan were here. Ou Haichao rubbed the formation that was destroyed by Win Xingtian, and after a while, he still shook his head gloomily: "The labyrinth is essentially a formation, and with his research on the way of formation, he may be able to easily find the core position." ”

Ying Xingtian ignored this meaningless assumption, lowered his head and thought for a moment, and then ordered the eight people of the Ruins Exploration Department: "There is no danger here for the time being, let's act separately." Remember the passage you just came from, use it as a base point to explore as many passages and domes as possible, and keep track of the distance - don't go beyond three passages at the farthest and beware of not coming back. Come on, on the table. ”

The eight people raised their wrists at the same time to reveal the military version of the smart watch customized by Qianlong Yuan, and each set the alarm clock for one hour according to Ying Xingtian's order: "Explore for forty-five minutes, and leave fifteen minutes to draw the scroll and return here to gather, understand?"

"Understood!"

Several people shouted at the same time, and the originally somewhat depressed momentum was instantly mobilized by Ying Xingtian's series of orders, and they quickly dispersed and began to explore different passages and dome buildings.

——The strength of these people is all middle-class and upper-grade martial artists, although they can't smash the passage like Win Xingtian, but as long as they find the place where the corridor or dome building is located, it is not a problem to smash a few more times to blast out a single entry and exit passage.

After a few people left, Ying Xingtian did not follow to find more Yongdao buildings, but sat down under the dome here, took out his tablet and wrote and drew on it, and the taste of thinking in his expression became stronger and stronger.

"That...... Do I want to check it too?" Ou Haichao stood next to him with a slightly embarrassed expression, no matter how skinless and faceless he was, he was still a high-level member of the "Yandao" organization at the same level as "Qianlong Yuan", if he was casually ordered by Ying Xingtian to call around, he would lose more than just his own face.

Ying Xingtian raised his head, his eyes were still full of thought, and he spoke after a while: "Brother Haichao, please continue to study the ventilation formation, I always feel that it can't only have the function of ventilation." ”

The latter shook his eyebrows, breathed a sigh of relief and nodded immediately: "That's right, the original design should not be for people to pass or survive...... Even if the construction workers were given air, it would not have to last for hundreds of meters. ”

So if it is deduced by normal logic, it should have a second effect. Ou Haichao thought and analyzed while speaking, and his eyes became brighter and brighter: "Maybe this second effect is the key to breaking the labyrinth!"

……

……

"Can you see what it does?"

Seeing that Yu Zhenzhen was squatting on the ground, leaning in front of the wooden array and studying for a long time, she kept whispering softly in her mouth, and she didn't know what she was talking to herself, Ji Yiming endured it for a while and finally couldn't help but ask.

The former stood up silently and shook the ponytail on the back of his head, his face looked slightly embarrassed: "I don't understand it." ”

(Then you study here for half a day...... ）

Ji Yiming shook his head speechlessly, and then turned to look at Gu Snake Xiaoyang's eyes: "Tell me to look at this, do you know it?"

The "Yin and Evil Anode Snake" of the Grandmaster Realm tilted his head, and his giant eyes showed a look of confusion.

"Forget it, I'll try. Ji Yiming remembered something, and also squatted down in front of the wooden array, and without much hesitation, he bit his index finger and forced out some blood, and carefully smeared it on the black fine formation.

"That's right, you are the Yellow Emperor's lineage!" Yu Zhenzhen's beautiful eyes lit up, and she stared at the changes in the array plate closely: "I should have tried this a long time ago, I don't have to work hard to study the first-class panda blood in Huaxia!"

Ji Yiming forcibly resisted the idea of complaining and didn't go back to her, and only after smearing all the formation patterns on the array plate with his own blood, he carefully retreated a few steps, waiting for the expected changes.

After about three or four seconds, there was a faint glow on the wooden array. The blood he smeared on it was "sucked" into it like a sponge by the whole round piece of wood, and then completely disappeared cleanly.

As if nothing had happened.

The two of them crouched on the ground and waited for a few more seconds, and even the faint light gradually faded away, and no further reaction appeared.

"Is there a little less blood? After all, the miniature formation hundreds of years ago must not have been well preserved as the normal formation. Yu Zhenzhen stared at Ji Yiming's finger that had just stopped the bleeding, and was eager to try: "I'll help you squeeze a little more, right?"

The latter sighed: "I'll come by myself." ”

This time, he was ruthless and directly bit a big bite, smearing the entire array of red blood gushing out like a needle.

The light lit up again, and a strange but strong formation fluctuation finally spread out from the array disk.

It's working!

The two of them were happy in their hearts at the same time, and their eyes looked at the wooden array without blinking, but their bodies were tense and their internal breath flowed, ready to deal with danger at any time.

Strange ruins and strange formations...... Coupled with the excitation method catalyzed by the bloodline of the descendants of the Yellow Emperor, God knows what kind of strange changes will occur in the miniature array disk hundreds of years ago.

One second.

Two seconds.

Three seconds.

Ji Yiming silently counted the seconds in his heart, and finally sensed the fluctuation of the formation on the array disk when he counted to three, and the original faint light became more and more dazzling, making the two of them almost unable to look directly for a while.

And then......

Yu Zhenzhen took out a sunglasses and put them on, and looked towards the center of the light without any abnormality.

"Hey, it's actually a photo formation!" she tilted her head, and the corners of her mouth showed an interested arc: "What do the images left by the ancient cultivators three hundred years ago say?"
