The air in this cave is extremely fresh, and there is a slight coolness, which is obviously blowing in directly from the outside, and it can be seen that the original design here is also very complete. Pen, fun, pavilion www. biquge。 info.The first letter of the new domain name Kele Novel Network (k1xsw), the largest free romance Chinese website, hurry up.

The entire cave exists underground, and if you don't do a good job of ventilation, it will be easy to produce miasma over time. People can suffocate to death when they enter it, and occasionally sparks can cause explosions, which is very dangerous.

There is no need to worry about this in the caves, because the ventilation in the caves is very good. When the wind enters, it can also expel the air from the cave, forming a fixed circulation pattern, so that no air will stay in the cave for too long to cause miasma.

At this time, Zuo Feng's first feeling was also his superficial understanding of the construction of this cave. However, what shocked Zuo Feng even more was his own feelings, a trace of extremely familiar longing sensation appeared in his body, or the beast soul in his chest that had been silent for a long time finally had a faint fluctuation coming out.

This feeling has not appeared for a long time, but whenever this feeling appears, Zuo Feng will feel excited from the bottom of his heart.

'Beast pattern, or beast crystal, there is such a treasure here. It seems that it is right to ask to come here this time, this Yao family is worthy of being a veteran super family of Xuanwu, and it has saved such a good thing. ’

Zuo Feng couldn't help but think in his heart, and at the same time, he unconsciously recalled what happened when he was in Linshan Villa. At the beginning, he obtained a beast pattern there, although it was only a small part of the complete beast pattern, but it benefited Zuo Feng a lot.

If you get the beast pattern here, you can also use it to improve your strength, and at the same time, you can quickly repair the injuries on your body. Although it is not bad if it is a beast crystal, the current left wind cannot be absorbed, and can only be temporarily preserved.

At the beginning, he had obtained a beast crystal during the trial of the spiral tower, and because he couldn't absorb it, he still put it in the corner of the nanocrystal, if he hadn't discovered it this time, he would probably have forgotten the existence of the thing.

Zuo Feng followed behind Yao Qiu'er quietly, and his expression became weird. I decided to come here in the first place, really to avoid the pursuit and recover my body safely. But when encountering the existence of this divine beast, Zuo Feng also had to obtain it.

Forcibly taking and grabbing is definitely not something that Zuo Feng can do, if you ask the other party for it, there is still some taste of merit and favor. I just saved someone's life, and then promised the other party that I would send it to a safe place, and I asked for something when I turned around, and there were really some things that were not very authentic.

Yao Qiu'er didn't know Zuo Feng's plans, and led the way ahead by herself, and the spiritual light stone in her hand was raised close to the rock wall next to her from time to time, as if she was looking for something.

With his previous experience, Zuo Feng also understood that the other party should be looking for the location of the opportunity, but although this mountain wall was artificially excavated, there was hardly anything special on the surface.

Before walking, Yao Qiu'er suddenly stopped, this cave has no end in sight at this time, it seems that there is still a long distance, and the light projected by the spiritual light stone can't see how far away it is at the bottom.

Between Yaoqiu'er put the Lingguang Stone close to the mountain wall, as if looking for something, and after a while, Yaoqiu'er seemed to have found something, her fingers groped for a groove in it, and she dug her hand into the groove as if to determine something.

Soon a smile of excitement spread across her face, and Zuo Feng understood that she was finally able to affirm the existence of this groove, which was the opportunity she was looking for.

A storage crystal in the thin chain in Yao Qiu'er's hand flickered slightly, and a crystal stone with a somewhat strange shape appeared in her hand. This crystal stone is generally used to make utensils, and can be a very fragile existence.

The crystal stone is clearly carved, and its own shape is very special. As an alchemy stone, Zuo Feng naturally has some understanding of utensils, especially this crystal stone. If you only make crystal bottles, you need to use a high-temperature vessel to refine and add some tough and solid materials to form it.

However, the crystal stone in front of me was not re-refined, but simply carved and polished and shaped, so that the crystal stone still maintained its original fragility.

Yao Qiu'er went deep into the groove of the crystal stone in his hand, rotated it slightly, and made a "click" sound from it, which not only included the sound of the mechanism after being activated, but also had the sound of the crystal stone being overwhelmed and cracked ears.

Zuo Feng looked at Yao Qiu'er with some surprise, only to see that the female doll's face had not changed in the slightest, and it seemed that she did not feel the slightest distress about the shattering of the crystal stone in her hand.

When the crystal stone in Yaoqiu'er's hand rotated to half a circle, it had already broken apart and fell to the ground. Haruka Qiu'er didn't seem to be slightly nervous until this moment, the strength of her hand weakened, and the speed of rotation became slow, as if she was also starting to get nervous.

When the crystal stone had fully rotated, the bracket had been fully activated, and a series of muffled sounds continued to sound, and at the same time, the subtle sound of water came from under his feet.

Zuo Feng's eyes flickered slightly, and he realized that this mechanism was also pushed by the hydraulic power of the underground river. It seems that this hydro-propelled mechanism should be used a lot, so if you have the opportunity to study it, you can pay more attention to it.

After this opening, the crystal stone had completely shattered and scattered all over the ground. The mountain wall, which originally seemed to be a monolith, slowly cracked, and an irregular boulder slowly opened, finally revealing a new hole.

The slowly opening stone door did not let Yao Qiu'er take a second look, but she carefully leaned down and carefully picked up all the broken crystal stones on the ground, leaving no trace.

Zuo Feng couldn't help but look at this Yao Qiu'er a few more times, and he also had a trace of admiration for this woman in his heart. The woman was so careful that even if someone came here through the previous mechanism, they would not be able to find exactly where the new cave was.

Seeing that the crystal stone on the ground had already died, Zuo Feng also admired the person who made the mechanism. The stone gate in front of him can no longer be described as heavy, the stone gate is almost half a zhang thick from the side, even if the strong person in the Qi refining period wants to break it, it will be difficult to achieve it in a few months.

And this crystal stone can only be opened once, and the next time you want to open it, you must have a new crystal stone, so that the initiative to open the mechanism is firmly in your own hands.

After Yaoqiu'er packed up the fragments of the crystal stone, she carefully put them into the crystal storage, and did not immediately enter the cave. Zuo Feng was still suspicious, but then he understood, because Zuo Feng could feel that the air in this cave seemed to have a strange smell.

Either there is poisonous gas in it, or there is a miasma in it because of poor ventilation. And now after the stone door is opened, the ventilation function inside seems to be turned on by the mechanism, and the air is constantly transformed after circulation, and the air inside gradually becomes fresher after such conversion.

After a while, Yao Qiu'er suddenly spoke: "You follow my footsteps for a while, enter here quickly, and don't have any stops." ”

After warning Zuo Feng, Yao Qiu'er walked inside, and Zuo Feng heard the other party's words and followed without hesitation. When Zuo Feng stepped on the position where Yao Qiu'er had just stayed, he felt that the ground seemed to sink slightly, but now he didn't dare to stay and could only follow quickly.

The two of them walked through the stone gate back and forth, and after a few steps, Zuo Feng felt that the ground under his feet had become solid, and the position of the subsidence under his feet before quickly bounced up. At the same time, the stone gate also began to move slowly, closed again, and completely restored to its original appearance with little effort.

Zuo Feng's heart moved, and he suddenly understood that this mechanism actually had a gravitational effect, and it would automatically close when a person walked into the stone door. If you stay for a while, when Yao Qiu'er walks into it and then enters, I'm afraid that Shimen will block herself out.

When the stone gate was closed, small holes appeared in the mountain wall in the stone cave, and then crystal clear medium-grade spiritual light stones rolled out of it, leaving in the grooves on the mountain wall. Suddenly, the entire cave was lit up, and you could see that there was still a long passage inside the cave.

It's just that this cave is not too long, you can see the bottom at a glance, there are two stone gates on the left and right, and there is a stone gate in the innermost part that is larger than the others.

Yao Qiu'er slowly breathed a sigh of relief when he arrived here, and walked towards the innermost, the stone cave next to him did not stop, and it seemed that he was only concerned about the things behind the innermost stone door.

"I'll go to the innermost stone gate, don't come to me for the time being. ”

At this point, Yao Qiu'er paused slightly, her eyes swept over Zuo Feng's fingers, she was observing the ring in Zuo Feng's hand, and said slowly: "There are some things from our Yao family in the other stone gates, if you are interested, you can look around, and if you need anything, just take it." ”

Zuo Feng nodded silently, and did not pretend to be a big head to refuse, on the surface he seemed calm, but in his heart he was secretly excited.

The other party obviously saw that he only had a low-level storage crystal in his hand, and the things that could be stored were very limited, so he generously let Zuo Feng take it at will. But how did she know that Zuo Feng still had a Najing here, and I was afraid that it would not be a problem to pack all the items.

Yao Qiu'er didn't look at Zuo Feng much, and walked straight towards the stone gate at the end of the cave, leaving Zuo Feng alone.

It wasn't until he watched Yao Qiu'er push open the stone door and walk into the stone room that Zuo Feng slowly exhaled a breath, revealing a look of crying and laughing.

After his eyes swept around the stone gate, he took the lead in landing on the stone gate on the right hand, raised his hand and pushed towards the stone gate.

The stone gate has a little weight, but there is no problem with Zuo Feng, when the stone door is opened, Zuo Feng's eyes flash slightly.
