The size of the Golden Silkworm Gu was extremely small, and Ye Yifan could probably estimate which section of the stone wall those people had entered, so after a brief investigation, a group of Golden Silkworm Gu worms drilled into the crack in the stone that was difficult to distinguish with the naked eye.

"Huh, it's so deep?" Through the Golden Silkworm Gu Mother Insect, Ye Yifan could clearly sense that those sub-insects were going all the way down, going deeper and deeper into the ground.

The speed of the Golden Silkworm Gu Worm was also quite amazing, and it only took a few breaths to catch up with the person in front of it, but that's it, in Ye Yifan's estimation, it had already reached nearly a thousand meters underground.

In the 21st century, many coal mines cannot dig so deep, and only oil wells will often appear more than 1,000 meters deep. But as we all know, although the oil well is called a well, it is actually impossible for people to go down, and there is only a thin eye that leads to the depths of the earth. But even so, the amount of manpower and material resources spent to drill an oil well is quite staggering. Not to mention the construction of a tunnel to a depth of more than a thousand meters!

"These guys must have some secrets, they have to find a way to catch up!" Ye Yifan thought about it and felt that there must be a way to open this stone wall.

"By the way, let those golden silkworm Gu worms help, there should be a mechanism inside, otherwise how would they come out?" Suddenly, Ye Yifan thought of this, and he immediately sent a few golden silkworm Gu worms to drill through the cracks in the stone, groping inside to find possible mechanisms.

"Found it!" Under the full search of the Golden Silkworm Gu Worm, an anomaly was soon discovered from inside the stone wall.

It's just that Ye Yifan is in trouble again, although the vitality of these golden silkworm Gu insects is not weak, and there are even existences with vitality of more than 5 points, but there is really no way to push the mechanism.

After all, the Golden Silkworm Gu Worm was too small to turn that mechanism.

"Hiss!"

At this moment, Ye Yifan discovered a poisonous snake through the Golden Silkworm Gu Worm, which seemed to have survived in this passage for a short time, and was attached to the damp stone on the top of the cave, looking around.

"Phew!"

Suddenly, the snake's body collapsed, and it fell directly from the top of the cave, and after falling to the ground, it bounced up again, like a broken grass rope, and seemed to fall to its death at once!

"Crunch!"

Then, unexpectedly, the snake attached itself to the mechanism and writhed desperately.

"Boom!"

Eventually, the mechanism was unscrewed under the impetus of the viper, and a thin crack appeared in the stone wall.

Seeing this, Ye Yifan hurriedly dodged and drilled in, and then the stone wall was closed again, and the golden silkworm Gu worm in the poisonous snake's body was also withdrawn by him, and it completely turned into a dead snake!

"Fortunately, I didn't alarm those people!" Through the monitoring of Ke Shao and the others by the Golden Silkworm Gu Worm, Ye Yifan found that they did not have the slightest abnormality, so he was relieved.

Although the sound of the stone wall was still quite loud when it moved, this passage was crooked, I don't know how many turns it had turned, and it was not really true to hear any sounds that collided back and forth below a kilometer, plus those people didn't expect someone to follow behind them, and they weren't too vigilant, so they were easily mixed in by Ye Yifan.

"Whoosh!"

After coming in, Ye Yifan did not relax his vigilance, but slowly walked along a very special route.

If Ke Shao and the others happened to see this scene, they would definitely recognize that every step Ye Yifan took was the one they had taken.

However, this situation only lasted for more than three hundred meters, and after arriving at a platform, Ye Yifan immediately relaxed, and when he moved forward again, he didn't need to worry about anything, and his speed suddenly increased a lot.

And the reason why Ye Yifan was so familiar with the mechanisms and arrangements here was all due to the large number of golden silkworm Gu worms he had released before.

In this regard, Ke Shao and the others, who had already entered the depths of the ground, were at a loss, they thought that the arrangement they had made was enough to pull out the tail that might exist behind them, but in fact, Ye Yifan knew all about it and mixed in very easily.

As Ye Yifan went deeper and deeper into the ground, instead of feeling the heat, a chill rose from the bottom of his heart.

"What kind of place is this?" Ye Yifan knew very well that the deeper he went underground, the hotter it should be, but the situation in front of him was completely unreasonable, which made him hesitate a little.

Although Ye Yifan now has a strong strength, he can be described as a master of art and bold, and he can go to no matter how dangerous the place on the earth is, but after entering this underground passage that leads to nowhere, he is getting more and more daring, and his heart is shrouded in a dark cloud, which lingers.

"It's here!" Just when Ye Yifan was about to lose his surname, there was a cheer in front of him, followed by the sound of a thick door being opened.

"Let's go!" In that period of time just now, not only Ye Yifan was anxious, but Ke Shao and the others were actually the same, and now they finally came to the end, and they immediately became excited, and they strode in, and even forgot to close the door behind them.

And this is cheaper than Ye Yifan. He followed closely behind the group, and as soon as he saw that the gate was still open, he turned into a shadow and swept past the gate while the people in front of him were focusing all their attention elsewhere.

By the time someone came back to their senses and ran back to close the door, Ye Yifan was already hiding next to a stone pillar not far behind the door, with the shadow of the stone pillar and the blind spot of people's sight, Ye Yifan had almost no possibility of being discovered.

"What kind of place is this?" After the person in front of him walked a little farther away, Ye Yifan raised his head and looked forward. And this look surprised Ye Yifan.

I saw that this was a huge square, and in the center of the square was a volcano, ah, no, to be precise, it was a magma mountain, the mountain was not high, only a few tens of meters, but Ye Yifan could feel the huge energy contained in it, and it seemed that it could erupt at any time!

However, around the magma mountain, there are a large number of machines, each of which emits a buzzing sound, and at the same time, it constantly shoots out strange white rays of light on the magma mountain.

But the strange thing is that although Ye Yifan is not far from the magma mountain, he can't feel a trace of heat, and he is still chilled, as if he has come to the South Pole. But the mountain in front of him that was surging with magma really told Ye Yifan that this was deep underground, and it should be extremely hot!

"Is it because of these machines? Why are they doing this?" Ye Yifan didn't make too many moves at this time, and after Ke Shao and the others in front of him ran to the vicinity of Magma Mountain, they immediately began to use the various materials they carried with them to maintain those machines, as well as replenish energy materials for them, and they were very busy, and at the same time, they also eliminated the possibility of Ye Yifan getting mixed up. After all, the people in that area have their own things, and their movements will not be too consistent, and from time to time, someone will raise their heads and glance around, wanting to blend in, unless Ye Yifan can learn to teleport in the game!

Thankfully, they didn't work long, and in a moment the row of machines near the gate was maintained, and the men took their tools and rushed to the next place.

"Hehe, it's just the two of us left now, let me have a good time!" Seeing that the others had already walked away, Ke Shaoyin came to Cao Xuejiao's side with a smile and pounced on it, as if he was planning to "rectify the Fa" right here!

"Ahh

Seeing this, Cao Xuejiao, who had always been highly vigilant, couldn't help but let out a scream, and then ran back a few steps sharply, avoiding the opponent's pounce.

However, because Cao Xuejiao had already tied her hands after entering here, she was extremely inconvenient in her movements, and she couldn't fight back at all, not to mention that she was not flexible enough even when she was running, and she was soon chased behind by Ke Shao.

"Little beauty, I'm here!" Seeing that it was impossible for the other party to run away, Ke Shao couldn't help but let out a low roar, and couldn't wait to open his arms, just waiting to hold Cao Xuejiao in front of him in his arms.

Speaking of which, this Ke Shao's character is not very good, but his strength is not bad, his vitality has reached 6.1, and it seems that his combat effectiveness is not weak, at least much stronger than Cao Xuejiao, who is a beast trainer.

However, just when Ke Shao felt that the overall situation had been decided, a huge fist suddenly appeared in front of his eyes, and then Ke Shao only felt dizzy and fainted.

"Shh

After knocking Ke Shao unconscious, Ye Yifan immediately put his finger to his mouth and gestured to Cao Xuejiao, who was standing aside and trembling.

"Whew!"

Cao Xuejiao naturally saw Ye Yifan's gesture clearly, and immediately reacted and stopped the screams that were about to exit.

"Let's go!" Seeing that Cao Xuejiao didn't make much movement, Ye Yifan couldn't help but feel relieved, he hurriedly picked up Ke Shao, who fell to the ground softly, and pulled Cao Xuejiao to run towards the gate.

At this time, the people in front didn't know that their companion had been put down by Ye Yifan at that moment, and after hearing the movement behind them, they only thought that Ke Shao had succeeded, and pulled the girl into the corner to do that kind of thing, and they didn't think that a little weak woman could make any waves!

"What kind of place is this, do you know?" Hiding in the shadows behind the stone pillars next to the gate, Ye Yifan asked in a low voice.

"I don't know, but according to my experience, they seem to be hatching some kind of animal! But it's strange, this incubation method is actually a cooling method, I have never heard of it!" Cao Xuejiao is worthy of being an animal trainer, and she suddenly thought of hatching animals. She obviously recognized Ye Yifan, so she behaved very obediently and had no intention of going against him! )
