Chapter 958: You can use it at your convenience

The air in this cave is extremely fresh and slightly cool. It is obviously blown in directly from the outside. It can be seen that the original design here was also very complete.

The entire cave exists underground. If the ventilation circulation is not good, miasma will easily occur over time. People will suffocate if they enter it, and occasionally sparks will cause an explosion, which is very dangerous.

There is no need to worry about this in the cave here, because the ventilation in the cave is very good. When the wind enters, it can also discharge the air in the cave, forming a fixed circulation pattern. In this way, the air will not stay in the cave for too long and cause miasma.

Zuo Feng's first feeling at this time was also his basic understanding of the construction of this cave. But what shocked Zuo Feng even more was his own feeling. A very familiar feeling of longing appeared in his body, or it could be said that the beast soul in his chest, which had been silent for a long time, finally had a faint fluctuation.

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.

‘Animal patterns, or animal crystals, there is such a treasure here. It seems that I was right to ask to come here this time. The Yao family is worthy of being an old and super family of Xuanwu, and they have preserved such a good thing. ’

Zuo Feng couldn't help but think about it, and at the same time, he couldn't help but recall what happened at Linshan Villa. I got a piece of animal pattern there, although it was only a small part of the complete animal pattern, but it benefited Zuo Feng a lot.

If you get the animal mark here, you can also use it to improve your own strength, and at the same time, you can quickly repair your body's injuries. Although it would be good if it were a beast crystal, Zuo Feng could not absorb it now and could only store it temporarily.

He had already obtained a piece of beast crystal during the Spin Tower trial, but it was placed in the corner of the nanocrystal because it could not be absorbed. If he hadn't discovered it this time, he might have forgotten the existence of the thing.

Zuo Feng followed Yao Qiu'er calmly, his expression becoming weird. When I decided to come here, I really wanted to avoid pursuit and recover my body safely. But when the existence of this mythical beast appeared, Zuo Feng had no choice but to obtain it.

Taking something by force is definitely not something Zuo Feng can do. If you ask for something from the other party, there is a sense of taking advantage of it and asking for favor. Having just saved a person's life, and then promised the other person to send him to a safe place, and then asked for something later, it was really a bit unethical.

Yao Qiu'er didn't know Zuo Feng's plan and just led the way ahead. Sometimes he raised the spiritual light stone in his hand and got close to the rock wall next to him, as if he was looking for something.

With his previous experience, Zuo Feng also understood that the other party was probably looking for the location of Ji Kuo. However, although the mountain wall was excavated manually, there was almost nothing special about it on the surface.

Before walking, Yao Qiuer suddenly stopped. The end of the cave could not be seen at this time. It seemed that there was still a long distance. The light projected by the aura stone could not see how far it was to the bottom.

In the meantime, Yao Qiu'er put the spiritual light stone close to the mountain wall, as if she was looking for something. After a while, Yao Qiu'er seemed to have discovered something. Her fingers groped for a groove in it, and she put her hand deep into the groove as if to find something. decide what.

Soon an excited smile filled her face, and Zuo Feng understood that she could finally be sure that the existence in this groove was where the mechanism she was looking for was located.

A crystal in the thin chain on Yao Qiu'er's hand flickered slightly, and a strange-looking crystal stone appeared in her hand. This crystal stone is generally used to make utensils, so it can be said to be a very fragile existence.

This crystal stone has obviously been carved, and its shape is also very special. As a refining stone, Zuo Feng naturally has some knowledge about utensils, especially this crystal stone. If you only make a crystal bottle, you need to use a high-temperature cauldron to refine it and then add some tough and solid materials to form it.

But the crystal stone in front of me was not re-refined, but simply carved and polished into shape. In this way, the crystal stone still maintained its original fragility.

Yao Qiu'er put the crystal stone in his hand deep into the groove, rotated it slightly, and a "clicking" sound came out from it. This sound was not only the sound of the mechanism after the machine was activated, but also the unbearable sound of the crystal stone. The heavy load produces a crackling ear sound.

Zuo Feng looked at Yao Qiu'er with some surprise, and saw that the girl's expression did not change at all, and she seemed not to feel any distress at all about the shattering of the crystal stone in her hand.

When the crystal stone in Yao Qiu'er's hand rotated half a circle, pieces had already broken into pieces and fell to the ground. It was only now that Yao Qiu'er seemed slightly nervous. The strength in her hands weakened and the speed of rotation slowed down. It seemed that she was also starting to get nervous.

When the crystal stone had completely rotated in a circle, the mechanism had been completely aroused, and a series of mechanical sounds continued to sound, and at the same time, the subtle sound of water came from under the feet.

Zuo Feng's eyes flashed slightly and he discovered that this mechanism was also driven by the water power of the underground river. It seems that this water-driven mechanism should be used a lot. If you have the opportunity to study it, you can pay more attention to it.

After being opened this time, the crystal stone had completely shattered and scattered all over the ground. The mountain wall that originally seemed to be a whole slowly cracked open, and an irregular boulder slowly opened, finally revealing a new cave entrance.

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

Zuo Feng could not help but look at Yao Qiuer a few more times, and he also had a little admiration for this woman in his heart. This woman was very meticulous. After cleaning up like this, even if someone came here through the previous mechanism, they would not be able to accurately find the location of the new cave.

Seeing that the crystal stone on the ground had died, Zuo Feng also admired the person who made the mechanism. The stone door in front of him could not be described as heavy. From the side, the stone door was almost half a foot thick. Even if a strong man in the Qi Refining Stage wanted to break it, it would take several months to achieve it.

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

After Yao Qiuer cleaned up the fragments of the crystal stone, she carefully put it into the crystal storage and did not enter the cave immediately. Zuo Feng was still confused at first, but then he understood, because Zuo Feng could feel that the air in the cave seemed to have a strange smell.

If there was no poisonous gas, there must be miasma inside because of poor ventilation. Now that the stone door is open, the ventilation function inside seems to be turned on by the mechanism, and the air is constantly changing after circulation, and the air inside gradually becomes fresh after such a change.

After a while, Yao Qiuer suddenly said: "Follow my steps in a while, enter here quickly, and don't stop at all."

After warning Zuo Feng, Yao Qiuer walked inside, and Zuo Feng followed without hesitation after hearing what she said. When Zuo Feng stepped on the place where Yao Qiuer had just stopped, he felt that the ground seemed to sink slightly, but now he didn't dare to stop and could only follow quickly.

The two went through the stone door in front and behind. After a few steps, Zuo Feng felt that the ground under his feet became solid, and the sunken position under his feet bounced up quickly. At the same time, the stone door began to move slowly and closed again, and it was completely restored to its original appearance in a short time.

Zuo Feng's mind moved, and he immediately understood that this mechanism was actually affected by gravity. When a person walked into the stone door, it would automatically close. If he stayed for a while, when Yao Qiuer walked in, he would probably be blocked out by the stone door.

When the stone door closed, small holes appeared in the mountain wall of the cave, and then crystal clear medium-grade spiritual light stones rolled out of them and remained in the grooves on the mountain wall. Suddenly, the whole cave was illuminated, and it could be seen that there was still a long passage in the cave.

However, this cave was not too long, and the bottom could be seen at a glance. There were two stone doors on the left and right, and there was another stone door in the innermost part that was larger than the other stone doors.

Yao Qiuer slowly breathed a sigh of relief when he arrived here, and walked towards the innermost part. He did not stop at the stone caves next to him. It seemed that he was most concerned about the things behind the innermost stone door.

"I'll go to the innermost stone door. Don't come to find me for the time being."

Yao Qiu'er paused slightly, her eyes swept over Zuo Feng's fingers. She was observing the ring in Zuo Feng's hand, and slowly said: "There are some things of our Yao family in other stone doors. If you are interested, you can look around. If you need anything, just take it."

Zuo Feng nodded silently, without pretending to refuse. He seemed calm on the surface, but he was secretly excited in his heart.

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 could she know that Zuo Feng also had a nano crystal here, and it might not be a problem to put all the items.

Yao Qiu'er didn't look at Zuo Feng for a second, and walked straight to the stone door at the end of the cave, leaving Zuo Feng alone there.

Until he saw Yao Qiu'er push open the stone door and walk into the stone room, Zuo Feng slowly exhaled, revealing a look of not knowing whether to laugh or cry.

After scanning the surrounding stone doors, his eyes first fell on the stone door on the right, and he raised his hand to push the stone door.

The stone door was a little heavy, but it was no problem for Zuo Feng. When the stone door opened, Zuo Feng's eyes flashed slightly.
