Black technology, Yang Qi finally saw what ancient black technology is.

After the stone wall was opened, there was a long corridor behind it, which was no higher and wider than the bomb shelter. Moving forward step by step, looking left and right on both sides, I found that the corridor that was about a hundred zhang long from beginning to end turned out to be that kind of mechanism wall. The rumbling sound from far and near just now was the sound of boulders moving and sliding.

Yang Qi knocked on the stone wall and found that the entire long passage was designed with exquisite mortise and tenon joints and joints, and the volume of the passage itself was cleverly dispersed and spread out before and after. To put it simply, if you don't open this burial cave in the right way, you have to dig through the 160 or 70 meters thick mountain. One hundred and sixty meters, the demolition palm has to be kneeling, and I am afraid that only a TBM specializing in tunneling can make a difference.

Such an organ is not much simpler than that of the Nanhuang Ancestral Temple. This ancient black technology is really black, and you can't see your fingers.

"Sure enough, the Divine Skill Book is the primary productive force. Yang Qi couldn't help but sigh. If there is no martial arts in this world, then it is impossible to build such a secret land with the strength of the whole country of Dali, which is a super project at the level of the eight wonders of the world. Even if you really set aside a bit of energy to build, it is not something that can be done in ten or twenty years, and it will inevitably make the people's resentment boiling and the people's livelihood miserable. If there is no need for other countries to fight, Dali's own people will not be able to tolerate such a monarch.

But look at it now, Duan Yu quietly made such a place. Although I don't know what method he used at the beginning, and how many strange people he asked for help, no matter how he calculated, it was always based on divine skills.

In this world, divine power can really be regarded as the primary productive force. When the capabilities of human beings themselves have increased unprecedentedly. The energy exerted is more amazing than scientific and technological means, and it is more adaptable and versatile according to local conditions. It's like if the Wanderers wanted to build a place like that. All it takes is a master of the organ and a group of disciples who have passed the strength of an elephant.

But Yang Qi's soul of a scholar couldn't help but pop up in front of this spectacle: "But." The movement of such a large tonnage of boulders, not to mention the structural problem, the key is where does its power come from?"

In ancient times, the mechanism mostly borrowed the power of flowing water, and used the waterwheel as the power source to promote the operation of the mechanism. But there is a limit to hydraulics, and the power output that can move so many boulders in just a few breaths is definitely not something that can be done by hydraulics.

It is also black technology, and the power source of the Southern Wilderness Holy Mountain is still traceable. The hot and cold convection generated by the lava lakes and meteorites below it, as well as the constant eruption of the Celestial Dragons falling to the ground and the Celestial Dragons rushing into the sky. can be a powerful power source. Diamondite is strong and not bad, and it is also an excellent load-bearing material. But what can be used as a driving force for the stable weather, peaceful geology, and calm waters near the cave?

"Leave that aside for now, just focus on exploring. "Jiao Niang led the team and went all the way. At the end of the passage is not an artificially excavated cave, but a large karst cave formed naturally. This cave is very wide, and the black hole is cold and secluded. The stalagmites on the ground are piled up on the left and on the right, like a cascading waterfall that is frozen instantaneously in winter, leading diagonally to the depths below. Then take the torch and shine it, and the stalactites looming high above. Like ghost fangs.

Overall, the cave looks like the mouth of a super monster. It is like a ghost path to the netherworld, which makes the faint-hearted shudder.

Ding Dong, Sanmiao plucked the strings, and the sound waves spread out, echoing and swimming between the stalactites and stalagmites, forming an extremely obvious echo, and it was clear that there was still a long way to go. In this secluded underground and complex terrain, it is easy to get injured if you are one foot deep and one foot is shallow. Fortunately, everyone present has martial arts, as long as the visual fear is eliminated, the speed of flying all the way is not slow.

The monk has run away, but there is only one path here, and he is not afraid of him running away. The group cautiously and quickly followed the huge karst cave all the way, and found that the cave was curved and coiled, undulating and undulating, but generally downward. Comparing the map, Yang Qi marked the route of the cave with her strong sense of direction, and found that everyone was advancing all the way under the Cangshan Mountain, and they were heading towards Erhai Lake.

After a short time, after walking a short distance, I heard the sound of flowing water, and it was obvious that there was an underground river near the left.

"Except that it's a rectum and there is no complicated cave nesting, this kind of terrain is quite familiar—isn't it, Sanmiao?" Yang Qi smiled and patted Sanmiao's shoulder, and Mrs. Sanmiao immediately smiled bitterly. For a long time, she regretted that she had attacked the Flower Shifting Village in the first place. If there had been no ghost obsessed with listening to people's instructions, there would have been no later qiē. (Who instructed it, and what the causes and consequences were, more on that later)

If she had been a little more careful in that cave at that time, she would naturally not have changed from a master of the Sanmiao Sect who trained others to a low-level person who was manipulated and taught. She regretted it for a long time, her bowels were green, her penitent skills had fallen, and her menstrual period was out of tune. But it wasn't until recently—she peeked at Yang Qi's side face, which suddenly overlapped with Jia Tengying's face, making her lose her mind for a while—yes, she suddenly began to think that this was not bad.

Get out of the rivers and lakes of the deceitful and come to the side of this adult, the soul of the three wonderful shaking M, and finally oh~ah~um~Yamei Daddy~~'s awakening.

"Huh?" was thinking about his thoughts, but saw Yang Qi suddenly frown, as if he had encountered some problem.

"What's wrong?"

"'Voice' is wrong...... Yang Qi put his hands on his ears and listened carefully, shaking his head while listening: "No, I'm not as good as a big wood in this regard, but the echo from the front is not quite right." Professional, you're on!"

"Yes!" Sanmiao was full of energy, and swayed a clear piano sound. The sound wave was transmitted, reverberated and resonated, and then came back into Sanmiao's ears, and then Sanmiao's brows were also tightly locked. The next moment, the purple light spread, the real and illusory smoke scattered in all directions, and Sanmiao's clothes fluttered and fluttered out, obviously going all out. She re-played countless piano notes, showing her music skills to the fullest, but in the end she was still stunned: "How can this be?!"

The sound in front was chaotic, and the area that should have been very simple turned out to be a blind spot for sound detection.

Sound power is not omnipotent, and Sanmiao is not omnipotent. In an extremely complex and noisy environment, there are times when she can't cover it, but only the environment like a sea of lava deep underground in the Nanhuang Ancient Temple can stump her. But now this cave is quiet and simple in structure, and those stalactites and stalagmites can also become a good resonance medium, like a tuning fork, which can increase the detection area of sound work. But just in front of him, not far ahead, the information transmitted back by the sound wave was suddenly chaotic.

It was as if the original painting had been torn apart and shattered into pieces, or as if a young child had walked into a labyrinth of infinite mirrors, and the difficulty of detection increased exponentially.

It's not the first time I've encountered such a strange thing, it happened once in the Qingcheng Mountain. If it weren't for the sudden disturbance of sound information, how could Sanmiao lose it. That time, she thought it was a coincidence, but when she encountered it again today, she realized that what was in front of her was not a coincidence—but her natural enemy.

So Sanmiao's expression immediately became solemn.

"Looks like we're not far from our destination. ”

A group of people walked not far away, and sure enough, the cave gradually became smaller and smaller, and began to tighten rapidly from a large large cave. Finally, an arch-like opening is formed. The opposite side of the cave was still a dark hole, and it seemed to be a large hole, but it was the place where the sound was completely disordered.

Just as Sanmiao put up a posture and wanted to try again at the entrance of this cave and explore the situation, he saw a figure rushing out of the opposite hole coldly. This figure is in a hurry, and there is no restraint at all. But it wasn't until he rushed out of the dark hole that everyone began to realize that this person's existence was as if his entire sense of existence had been obscured by something.

With a whirl, the man hit the two airbags at the entrance of the cave with a smooth head.

With a snap, a devil's claw grabbed the bald head and instantly pressed the man. Yang turned his head ninety degrees again with a click, forcing the man to notice his unhappy expression: "Are you still here for this? Aren't you afraid that our family's Sanmiao will pop your eyeballs? Besides, what are you running outside, do you want to abscond with the treasure?"

That's right, this sudden bald head is none other than Duan Xingyong.

"Huh?!" Unexpectedly, Duan Xingyong was even more surprised than here, he widened his eyes and glanced around in disbelief, and found that he had really returned to the exit, and then yelled nervously: "How could it be! How could it be! I obviously went inside, I obviously saw it, why did it ...... This can't be, this can't be!"

Duan Xingyong waved his hand and shook his arm to break free and return to the cave, but Yang Qi would let him sway again. Whoosh, as soon as Duan Xingyong was thrown aside into He Qiyu's hands, Yang Qi clenched his fists, shook his neck, shook his shoulders, and entered the new map with a sharpening knife.

Stepping into the cave, Yang Qi mentioned all the five senses, and his eyes were full of gloom, and he found that the environment here was extremely complicated. There are both natural landscapes and artificial stone walls, which are mixed together but are natural. There was still a little natural light, but it was blocked by the cascading obstacles. There are many obstacles in front of and behind him, his vision and hearing are not open, and no matter where he goes, he has to go around and around without a straight road. While she was memorizing the route with her heart, she heard a loud noise, and the artificial walls suddenly rose and fell one after another.

This one rises, that one falls, but in a breath, the original landscape is completely different, completely changed, and the path just written down is completely useless.

"It seems that this reputation has also left us with a homework problem. It just so happens that I'm just feeling a little bored—" (To be continued......)
