Glancing lightly at Balu's somewhat guarded eyes, Zheng Chen took out a bullet case from his sleeve again, filling primer, gunpowder, bullets Zheng Chen didn't do much, but he had done it before, so the process was fast.

Click――

"Where are you going next?"

"This ......" Balu seemed a little hesitant, not knowing whether to tell Zheng Chen, Zheng Chen had already stood up when he hesitated.

"Forget it, tell me how to get out of here and I'll go." Saying that, he was ready to take Lei and Xiya to leave, this encounter can be said to be another unwarranted disaster, and Zheng Chen has nothing to say about it.

"Well, that's fine." Balu scratched his head a little embarrassed, "The previous exit and the nearby exit must not leave, but other places are still okay, I'll lead the way." ”

It's not that he doesn't want to be separated from Zheng Chen, but it's especially easy to get lost in this kind of underground mine, and he hasn't been bad enough to do it on purpose.

"Strange, Grandpa Bohm doesn't seem to have returned." When passing through a special cave, Balu thought for a while, suddenly extinguished the small oil lamp in his hand, and the surroundings suddenly fell into darkness, when he was about to do this, Zheng Chen noticed it, but after that, even if the surroundings returned to darkness, he didn't hear any running footsteps.

On the contrary, there was a new change in the surrounding environment, and the stone wall of the ground above his head was glowing with a brilliant pale cyan light, as if he was in the stars, although these lights could not completely illuminate the place, but they did not affect the vision much.

"Wow! It's so beautiful! Xi Ya squatted down in surprise and touched a spot of light under her feet, "The stone is glowing." ”

Zheng Chen also looked down, stretched out his hand to touch it, his expression moved slightly, now he has a habit of using the texture to sense it when he encounters something special, as long as it can make the texture react, it is definitely not an ordinary thing, such as the stone under his feet, ordinary stone lines will not be shaken, but the stones under his feet react, "What's wrong with these stones?" ”

"Well, Grandpa Bohm said that there are a small amount of flying stones in the stones here." For this problem, Balu did not hide it, although there are trace amounts of flying stones, but mining is a problem, otherwise this place would not be abandoned, as long as the flying stones contained in the stone will immediately become ordinary stones as soon as they encounter the air.

"Flying Stones?" Zheng Chen frowned slightly, did he mean the Flying Stone? This place is also connected to the continent of Worusione?

Seeing that Zheng Chen really didn't understand, Balu scratched his head and explained, it's not good to go out now, it's safer to hide underground for a while, so he directly explained what he knew, anyway, many people sound like a story.

Zheng Chen sounded the same way, because Balu saw that he listened very seriously, so after explaining the legend of the flying stone, he unconsciously talked about the things he knew, such as the legendary 'Sky City' in this continent, which belongs to the legacy of the ancient Laputa people, but this is just a legend for the people of this continent.

After all, no one has seen the so-called Sky City for hundreds of years, but of course Balu doesn't think so, his father was lucky enough to see the Sky City in his lifetime, but he just came back to make others sound too mysterious, and was regarded as a liar.

After finishing speaking, Balu realized that he had said a little too much, but looking at Zheng Chen's careful listening, he had some expectations, "That...... Do you believe in Castle in the Sky? ”

"Faith." Zheng Chen said flatly, the reason why he believed it was not because of Balu's words, but he mentioned something that Zheng Chen was familiar with, according to his father's account, Sky City was shrouded in a super-large tornado.

Before you come here...... He'd seen it, and with Xiya's induction, that place should be the location of the so-called Sky City.

"A super-sized tornado? Isn't it the nasty tornado we saw earlier? Xi Ya suddenly said suspiciously.

Zheng Chen glanced at Xi Ya, this hasn't been forgotten until now? Could it be that the tough plant there impressed her too much?

"You've been!?" Hearing Xi Ya say this, Balu was suddenly excited, including the girl behind him was also a little excited, although he got enough evidence from the girl behind him and Grandpa Bohm to prove the existence of Sky City, but he didn't see an example, he was still a little unconfident.

Now there is a person who has seen the castle in the sky!

"I didn't go in." Siarsa held her chin and noticed that Lei's expression was a little confused, she smiled lightly and explained, "When Lei fell asleep, I sensed that there must be a great plant there, and I wanted to take you to see it." ”

She shook her head, a little regretful, "It's a pity that the tornado there is blocking our way. ”

“…… Dad really wasn't wrong at all. Balu muttered, and then he exclaimed quite excitedly, "Big brother, thank you so much! ”

Zheng Chen glanced at him, and the hand on the ground moved slightly, and the lines on his body instantly spread to his hands, but this time the spread of the lines did not stop, but continued to extend outward, and after extending out, Zheng Chen felt that his physical exertion began to increase!

And as the spread of the pattern expands, the consumption of physical strength is increasing extraordinarily!

Is this an exceptional mining model?

Zheng Chen raised his eyebrows slightly, and immediately withdrew the palm pressed on the ground, the light spot on the ground had disappeared, and the trace flying stone contained in the stone had been completely refined and extracted.

The number of flying stones extracted was very rare, Zheng Chen's heart moved, and some powder crumbs that emitted a light blue light in the darkness appeared from the lines on his palms that had not yet disappeared.

A strange feature of the texture, as long as the things other than metal are stored in the texture, they are either liquid or powder when they are spit out.

These flying stones that appeared in Zheng Chen's hands slowly drifted away from Zheng Chen's palms and continued to fly into the air.

It wasn't until I touched the stone wall above my head that I stopped.

“…… This is the Flying Stone!? Balu also noticed the light floating in Zheng Chen's hand, and exclaimed in surprise, "It didn't turn into stone?" ”

"Probably, take a break here." Zheng Chen said that he planned to extract some flying stones from this place and keep them as a backup, although those trace amounts of powder played a small role, but if there were too many of them, they might be able to be useful at some point.

Zheng Chen's storage space went through strict calculations when he left his ears, and even a part of the rare metal he obtained was discarded, in addition to bringing some required items, he also left a part of the space.

The speed of collecting flying stones is not very fast, and the number of flying stones here is very small, and it is not necessarily how many will be completely emptied of this mine.

With a slight movement of his mind, the lines that spread on the ground quickly expanded, almost covering a quarter of this small mine, but in less than five seconds, Zheng Chen's physical strength was extracted by most of the activated lines!

Without hesitation, he immediately removed the lines covering the ground, and these lines spread out quickly, and the speed of withdrawal was even faster, and they disappeared completely in the blink of an eye.

Feel the number of flying stones extracted, a very small part, not as much as the size of a thumb.

"Strange, how did this light go out so much?" Balu said with some confusion, took out the oil lamp again and lit it, and the pale cyan light shrouded in the mine immediately disappeared.

After recovering his physical strength, Zheng Chen repeated what he had just done, because of the problem of retaining his physical strength, the speed at which he extracted the flying stones was not fast, and after extracting all the nearby flying stones, more than an hour had passed.

Lei didn't say much, but Xiya was like a bosom sister, and the girl who followed Balu was called Xida.

Zheng Chen shook his head, they had never seen Xi Ya's murderous appearance when he ran away.

Anyway, the flying stone here has been completely extracted, but the amount is a little unsatisfactory, and the overall volume is less than the size of a palm, but it is much larger than the one on Xida's body.

A hollow metal ball was molded out of his hand, Zheng Chen's fingers were pointed in it, and the flying stone stored in the texture was injected into it through the lines, and the metal ball immediately had an additional buoyancy that rushed upward, and it almost flew out of Zheng Chen's hand.

Stretched out his hand and grabbed the metal ball tightly, but he himself was taken away from the ground, and at the moment when it just rose, Zheng Chen took back the flying stone powder injected into it, and the buoyancy on the metal ball quickly disappeared with the withdrawal of the flying stone powder.

Although the quantity is very small, but because it has been refined by the grain, it is not bad at all in terms of quality, at least it is not worse than the flying stone on Xida's body, but it cannot be compared in terms of controllability, otherwise, she should have been taken to the sky with that flying stone a long time ago.

However, this did not happen, and only played a role in the danger of her falling from the sky, so the ancient Laputas must have had the technology to process flying stones.

Flying Stone and Flying Stone do not belong to the same substance at all! The latter loses the ability to fly after processing, and the former is not processed...... Doesn't seem to work at all.

"Let's go." After resting almost, Zheng Chen stood up, he had been here long enough, even if those people were chasing Balu and them, it was time to retreat at this time.

"Oh...... Good. Looking at Zheng Chen with some doubts, even though Balu had some doubts in his heart, after seeing his expressionless face, he held back his words.
