The walls of the lower layer of Sky Castle are very compact, and there are no traces of glue or splicing from the outside, but there is another part of the power to bring them together.

"Who the hell are you!?"

Very vigilant and vigilant voices came from all around, Zheng Chen glanced around, the voice appeared around out of thin air, and the source was not clear!

"The voice?" Sida was a little confused, "This voice seems to be the one who grabbed me......"

"The Flying Stone in your hand?" Zheng Chen withdrew the Jade Wind Sword that was dotted on the gap in the wall, and asked lightly.

"Answer my question!" The voice shouted a little anxiously, after mastering the Sky City, he thought that he was the supreme controller here, but the monsters that appeared on the upper level of the Sky City made him feel a sense of threat.

Can the robot soldiers in Sky City really be able to deal with each other?

The ultimate weapon in the lower levels is strong, but this is only against the ground and cannot attack the upper space of Sky City.

And Zheng Chen is the young man next to the rampaging monster mother, and the other girl next to him can be transformed into a weapon, which makes him surprised and a little curious at the same time, this is not a product of Laputa, there is no record at all, and the girl who can be turned into a weapon......

He is not like a dirt bun like Balu, he still knows something, and it should be a characteristic race in another continent.

Did the outland's hand reach out too!?

In any case, the people who control Sky City are quite reluctant to see people from outside the world get involved in the incident.

Without speaking, Zheng Chen whispered, Xida beside him heard it very clearly, this whisper was a kind of chant with a kind of charm, and with the end of the chant, the sword of the emerald wind spontaneously surged out of the condensed wind.

"Strings of the South Wind!!"

The wind was surrounding the Emerald Wind Sword, and the wind ring shrouded in the Emerald Wind Sword shrank suddenly, and at this moment, Zheng Chen's sword stabbed into the gap in the wall in front of him, and the tip of the sword stabbed into less than half an inch before stopping, and the wall in front of him was not like metal, but more like it was made of special stone.

In terms of hardness, it is superior to steel, and even if the sword of the emerald wind is sharp, it can only leave a trace that is not too deep.

The wind roared from the tip of the sword, and the surrounding walls shook strongly in the wind pressure that crashed into the cracks, not shattered, but scattered independently, and now it can be completely determined, this wall is really like a building block!

The structure inside is made up of a large number of blocks with carved patterns

The reason why it can be so closely linked is that it must be related to some technology in the sky city, after receiving a strong impact, it will not be shattered, but in this scattered way to share those impacts, and when the impact is over, after recovery, it will be combined immediately, as for the internal situation, the same is true!

"Let's go!!" After the wall was completely opened, Zheng Chen waved the sword of the emerald wind, the spiral wind was still preserved, and a passage composed of wind was traveled, and the surrounding squares continued to squeeze the wind circle, without hesitation, Zheng Chen picked up Xida and stepped on the wind circle and quickly rushed in!

The crumbling wind circle was completely crushed, and Zheng Chen and Xida also broke in, but the place where he was a passage full of several roots, because of the perennial growth of these tree roots, it could be seen that the block formed in it was partially stretched out by many roots.

Looking for some parts with larger openings, Zheng Chen directly cut a few roots of that part, squeezed in from it, paused slightly, he glanced at his left hand, and asked Xida, "Do you know where that person is?" ”

"......" Hilda shook her head in confusion, she knew the spell about the Flying Stone, but she didn't know anything about the structure here, "it must be in the very center." ”

"Check it out." After thinking about it for a while, Zheng Chen temporarily terminated the agreement, and at this time he had already broken into the lower area of Sky City, so there was no need to maintain the agreement and continue to consume power.

Quickly winding the Fenghuang talisman back, Zheng Chen frowned slightly, not wanting to find a way to eliminate the influence of the black particles, and the time of the contract would only get shorter and shorter.

"You abominable intruders, get out of here!!" The man's voice was still lingering around, and he couldn't find the other party, but the other party could grasp their movements, and it should be some kind of monitoring system here.

Zheng Chen directly ignored the other party's words, and at the same time constantly adjusted the direction of movement according to the change in the other party's tone.

The other party's tone became more and more urgent, "Damn, you forced me!" ”

The lower area is not large, probably because it is loaded with a lot of technology, and the structure here is not as troublesome as a labyrinth.

Zheng Chen, who was advancing, suddenly stopped, picked up the Lei next to him and Xida behind him with his left and right hands, and ran backwards, a dark golden thunder light blasted out from one side, only the finger-thick thunder light was extremely destructive, and the strong explosion light covered all the nearby passages.

The few that covered the passage were all incinerated.

By the time the flames of the explosion had disappeared, the temperature had risen considerably, and the textured blocks that made up the lower areas had been damaged.

"Damn!" The other party's angry scolding came from the passage.

This kind of attack may be able to be used all the time here, but he also has a lot of scruples, and he doesn't dare to use it at will, it's okay if he hits, if he can't hit, the dark golden thunder and lightning power will destroy the cornerstone here, and in the sky city where things are at its peak, there may be guards here.

Now, he is the only one who controls this place, if he attacks without fear, maybe he hasn't solved Zheng Chen yet, and he will let the cornerstone of this place be destroyed first.

Is this guy also a monster, he was able to sense something wrong in advance and deal with it immediately, which was a great blow to his confidence.

And Zheng Chen's position is constantly close to where he is...... The opponent's combat power is obviously not something he can compete with.

Even if there is no girl who can be turned into a weapon, she can kill herself in seconds just with Zheng Chen's reflexes and speed, and Romuska, who judged the poor contrast in force between the two sides, looked at the projection in front of her and sweated profusely, and her tone became a little more flustered.

Along the way, those small attack stone pillars that bounced out were all advanced by Zheng Chen, and instead of producing any good results, they brought a lot of damage here.

Zheng Chen looked down at a severely cracked block with a severely cracked shell under his feet, revealing a faint cyan glow and some other parts, "These are flying stones?" ”

Sida looked at the pale cyan light inside the veined block in some surprise, this light was all too familiar to her.

"......" Zheng Chen calmly stretched out his hand and pressed it, and the lines on his body spread out directly, touching those pale cyan lights, and sure enough, these flying stones could also be extracted!

Although the amount is small, it can already allow him to guess some problems.

There's a big reason why these blocks fit together so closely, and there's a big reason why these flying stones fit together!

As the flying stone was extracted, whether the effect of this grain block was lost or not needed to be further tested, Zheng Chen stepped on it with one foot, even if the shell was cracked, the texture block was still very hard, and this foot stepped on, making this texture square sink slightly.

And so it was! After losing the Flying Stone, these veined blocks no longer have their original purpose, and the machine loaded in them can affect or control the power of the Flying Stone.

Squinting his eyes slightly, Zheng Chen once again stretched out his hand and pressed it on the ground, this time not in the dark mine, so Xida clearly saw that a piece of gray lines spread out from Zheng Chen's hand, and these lines extended directly into the crack of the pattern square, and then the faint cyan light emitted from the crack of the pattern square completely disappeared.

The broken pattern blocks in the vicinity all failed, and after pulling the bud, Zheng Chen stepped on the ground again, and this time the pattern blocks that were stepped on did not appear a little lower limit, but there was a chain reaction collapse, and all the texture blocks that lost their effect around them fell downward, allowing Zheng Chen and them to come to the next layer of the passage.

Not only was Xida speechless, but Romuska, who had been observing Zheng Chen's situation here, was also stunned, his attack just now actually allowed Zheng Chen to grasp the weakness here, he actually destroyed the pattern square!

You know, he just had a lot of texture blocks damaged.

I didn't have time to be stunned, and when I saw Zheng Chen leading Lei and Xida to a stone gate, he quickly picked up the pistol on his body, and stared at the entrance of the central room with a wary face, this place is the core of the lower space, which is known from the relevant information and text translation booklet in his hand.

The protection of the central area should be very strong, right?

This thought had just flashed, and when he was still thinking about how to deal with Zheng Chen outside, a strong wind rushed in, blowing his heart cold!

"Get some rest." Reaching out to support Lei, who was about to fall to the ground as soon as her body was about to fall to the ground, the entrance here was very strong, and after breaking through here, Lei's already insufficient strength had been exhausted, and after gently placing her on the ground, she quickly rushed to Romuska who raised his pistol and aimed it at them.

When approaching him, on the side of his face, a bullet grazed Zheng Chen's cheek, and before he could fire the second shot, Zheng Chen was pinched by the neck and instantly pressed to the ground, and after subduing him, Zheng Chen had a chance to take a look at the surrounding environment.

No wonder that the giant tree was able to grow to such an extent in Sky City, it turned out to absorb the energy emitted by the flying stone, a super-large flying stone......
