After the wall was broken, what was revealed made Tang Yu look straight.

It turned out to be a huge and simple, interconnected gear set.

These gears are made of wood. It seems that they have a history of thousands of years. But at the moment, because Tang Yu broke the wall, several gears burst, and the whole gear set has stopped rotating.

Tang Yu took a look at it and noticed that there was something like a loudspeaker in every three connected gear centers. However, the problem was that this thing was not used to amplify the sound, but as if it was used to amplify the wind. Looking at the embedded gears, Tang Yu roughly calculated that after the gears were rotated, they would There will be a gust of wind, which is enhanced by the loudspeaker like device and then transmitted to the corridor where Tang Yu was at the beginning. It is the wind that makes him feel very irresistible.

These loudspeakers are not the same size, but they are just as good as those holes in the wall, so Tang Yu has such a guess.

"What kind of race is this unicorn? Even these mechanical things can be built? " Tang Yu's face was shocked.

After all, although the technology has been in the mainland for a long time, even if it is a kind of old technology, Tang Yu does not know what the old technology is.

Mechanical civilization?

Because Tang Yu broke such a piece of about five gears, the whole gear set stopped rotating, so there was no wind in the corridor, and the consumption of genuine Qi in Tang Yu's body naturally stopped.

Tang Yu was still dumbfounded, thinking that it was unscientific! Up to now, he is still a bit confused, saying that the emergence of this technology should not be.

But it did appear in front of Tang Yu. Even if Tang Yu didn't believe it, he had to admit it.

After hesitating for a moment, Tang Yu slowly walked out to the front of the corridor.

The whole corridor is about one kilometer. The gear set broken by Tang Yu is only one hundred meters away from the entrance of the corridor. He doesn't know if there will be anything else behind. He hears the sound of gears turning in the air. Therefore, he thinks that the damaged gear set in front of him should only be a part of the current situation.

The emergence of this kind of thing with a little bit of science and technology is just a little bit. At least for the science and technology tree of this continent, it does have some scientific and technological content. Tang Yu has to be cautious about it.

To say that Tang Yu destroyed all the gear sets all the way. To be honest, Tang Yu didn't know whether he could do it or not, and he didn't want to destroy these things for the time being. After all, it was not easy for this thing to appear, and he didn't know whether it was unique. So Tang Yu wanted to see carefully whether they had other functions.

It's about 100 meters away again!

Tang Yu noticed that the holes on the walls on both sides became regular "W" shaped hole belts, which were less than 20 cm in length. One of these holes appeared on the wall, which was arranged from top to bottom, and the left and right sides were aligned.

Tang Yu didn't immediately go up. After a moment's hesitation, he wanted to try it first. What new things would appear in this section of hole that had obviously changed.

Then, he took out a piece of flint and controlled it to drift towards the front corridor.

It's really floating!

The speed is very slow. Every minute, it will only advance less than one meter. This is what Tang Yu deliberately made.

"Chi!"

At first, the corridor did not respond at all, but just after the flint was about 10 meters forward, there was a sound of light chanting in the air. At the same time, countless murderous gases were ejected from the side "W" shaped hole belt.

Tang Yu could clearly feel the murderous spirit, and even made him feel a little chilly.

Tang Yu can be sure that this kind of murderous spirit did not come from living creatures. So

"Bang!"

Tang Yu only felt his head tremble. The fire stone in his eyes broke into powder and disappeared in the air. Even the aura in the flint was swallowed by something and disappeared.

Tang Yu's eyes widened and his face was full of surprise. He didn't see anything in the hole belt. Of course, his eyes didn't see anything, but he felt it. Although it passed by in a flash, the thing flashed away. In an instant, it burst the fire stone and disappeared. Even though Tang Yu's strength was very strong, he still could not find its trace Trace.

"What the hell is it?" Tang Yu mumbled and thought for a while. He hesitated whether to break the wall or not, to see what was hidden in the wall.

"Why don't you try again and see if you can find anything?" Tang Yu had a feeling that if he broke the wall, he would not be able to find out what it was that attacked Ye Huoshi. This feeling made him feel the pain of birds.Once again, he took out an industrial flint. Tang Yu controlled it more carefully and slowly drifted to the interior of the corridor. This time, Tang Yu observed it more carefully.

"Bang!"

But it is still 10 meters ahead of the position, the industry flint will be the hole belt, the impact of things, broken.

This time, Tang Yu more clearly captured this thing, but it was a little inconceivable, because he was surprised to find that this kind of thing attacking the industry flint is actually air.

That's right!

It's air!

It's a device like an air cannon, compressed air, and it's quite violent, but the problem is

Tang Yu once again took out a piece of flint and squeezed it hard. The flint was only broken into several pieces. If he wanted to turn it into powder, Tang Yu admitted that even he needed to use half the strength of his whole body.

"Hiss!"

Tang Yu forced hard, and the flint broke into powder and fell from his hands.

"How terrifying is the power of this air cannon?" Half of Tang Yu's strength is enough to wipe out a strong man of three or four stars in the central God realm. This air cannon device seems to be more domineering and thorough than Tang Yu's means. Even the aura of the broken fire stone is also wiped out together.

Tang Yu couldn't believe this. He always felt that he didn't notice it. Otherwise, how could an air cannon have such a huge power.

But after thinking about it for a long time, Tang Yu didn't come up with a reason. He hit the wall with a fierce face.

"Bang!"

This time, the wall was not so easy to crack, and Tang Yu had already guessed this point, so he did not hesitate to punch again.

After three punches, the cracks on the wall finally couldn't bear the huge damage, and the "KaKa" splintered, revealing the same gear set as before.

Because of the bearing capacity of the wall, it became more and more huge. This time, the gear set was not damaged because of Tang Yuqiang's fist strength. It was still intact and slowly running in front of Tang Yu.

"Is this the device that releases such a powerful air cannon?" Tang Yu glanced back and felt that there was no big difference between this gear set and the previous one! The only difference is that the loudspeakers, on the other hand, have turned into miniature devices, with the big mouth facing the gear and the small opening facing the gallery.
