In the dark passageway, the trio moved slowly, hissing sounds echoing around them. However, the sound was a little different from the first time they had heard, a chaotic sound like a spring gushing water.

The hiss they heard this time was nearby, and it made people hear it very really, like a jackal smiling fox, full of a sense of mystery and gloomy.

At the same time, when the sound sounded, there was a cool breeze accompanied by a cold breeze, which made people shiver and feel cold air coming from their backs.

At this moment, Stygian felt that his heart was about to burst out, and only by clenching the weapon in his hand could he keep himself calm and not be overwhelmed by this tense atmosphere. But when he saw the other two, he was stunned.

Needless to say, he is very in awe of this person now, after all, the other party's former power is personally experienced, if the other party is panicked at this time, they don't have to mix. However, what made Ming Ye puzzled was that Mu Qingchen, a weak woman, was also fearless at this time, although the whole person was still the same face, but at this time, the original feminine transformation gave people an extremely strong and masculine feeling, which looked heroic.

"Could it be that this Mu Qingchen is actually pretended to be Wang Junji or Brother Chun?" His brain really couldn't turn around at this time.

The hiss seemed to know that someone was approaching, and the movement became more and more poignant, louder and louder, and the expressions of the three of them became more and more solemn.

The flames in Mu Yan's eyes were almost burning, and he stared at the front of the passage, holding the dispensed stun gun in one hand and a ring carved with intricate patterns in the other. After all, he didn't know if the alien was afraid of electric shocks, and if it didn't work, he could immediately take out his telekinesis pistol.

"Huh? Is that....... ”

Although the atmosphere was extremely tense, a strange expression appeared on Ke Mu Tole's face, as if he was smiling bitterly.

When the three of them came to the place where the sound came from, Mu Qingchen and Stygian also showed his wry smile.

Shen Ye frowned, looked at the large and small honeycomb-like holes on the wall, and said depressedly: "This ......, this is why you rely on this to make such a terrifying sound?" This is the source? ”

It's no wonder that he is depressed, even Mu Tolerance and Mu Qingchen are extremely speechless in the face of the things in front of them.

At the end of this passage, there was only a broken stone wall, which was full of holes, and the few people who made a hissing sound naturally understood.

When the air is circulated here by the modified air facilities outside, it will make a strange hissing sound, and because the sound is blocked by the cave wall and cannot be transmitted to other places, it can travel very far in the passage, and the sound it makes is different for each segment.

Mu Qingchen approached, and after reaching out and touching this wall, his eyebrows furrowed slightly, and he said softly: "There is no slime on this wall, and the soil on the wall seems to be very soft." ”

For her analysis, Mu Tolerance only nodded in understanding, and then he turned on the communicator, ready to contact Gao Chenke and them.

"Drip ...... Drip......! ”

"Huh? What's going on? He suddenly found that his communicator could not connect to the other party, and after pressing the communication, there was only a busy sound inside!

At this time, Mu Rong's heart that had just been put down suddenly hung a little again.

You must know that this is only a side quest, and if something goes wrong with Gao Chenke and their team, then none of the three of them will survive.

Contacting the other party, he immediately contacted the Prometheus.

"Drip ...... Drip......! ”

It's the same busy sound, and I can't connect at all.

"Is it signal interference?"

"Captain Murong, come and see! There's a door inside the wall! Just when he was guessing what the reason for the video communication, Mu Qingchen suddenly snorted softly!

"Door?"

Mu Yan looked up and saw that the stone wall that made a strange noise had been dug open by the Stygian with the power glove, revealing what was inside, which was part of a stone door!

After walking in, Mu Rong squinted his eyes and carefully observed with the allurized spirit jade.

On this exposed stone door, there is a very simple latch, just like the latch of the Zhumen in ancient times, which is a kind of pull ring.

Looking at the stone door that suddenly appeared, Mu Yan ignored the two of them, quickly activated the task stone in his hand, and summoned a blue flickering light curtain.

When the light curtain appeared in front of the three of them out of thin air, he didn't give Ming Ye and Mu Qingchen any chance to take advantage of, and directly switched the list of personal attributes to the task introduction list.

"Side Quest: Help the Exploration Team find out everything about the unknown passage and leave Elizabeth during the mission. Shaw, Holloway. Charlie. ”

"Complete side quests to reward 600 ocean supply points and 1 D-level ocean supply card."

"Mission Limit: Up to three participants."

"Unfinished!"

The three of them were like avatars when the blue light curtain illuminated, but none of them could laugh.

Unfinished, these three big characters, although they are at the bottom of the light curtain, are the most dazzling existence.

"Hades, the soil of this stone wall is soft, you dig this door out for me, let's go in later!" Mu Yan didn't give the underworld any room for refutation at all, and gave the other party an order directly in his tone.

Facing the order from the deputy captain, Ming Ye looked at Mu Qingchen, and saw that the other party had changed back to her feminine appearance at this time, he shook his head helplessly, and replied angrily: "Got it!" ”

Although Mu Tolerance is the strongest in this, but the Stygian is the most suitable for dry excavation, although Mu Qingchen has exposed his skills, but this only shows that the other party's weak body contains a certain degree of strength. And although Mu Yan had digging tools in the space ring, he didn't want to expose this kind of thing in front of the two of them.

Therefore, Hadesno has a power glove with protection and strength, and it is the most suitable person for this kind of heavy physical labor.

"Bump ......! Bang......! ”

As the stone wall was gradually cleared out, the stone gate inside finally revealed its original appearance!

Twenty minutes, when all the digging was done, Hakno was also sweating profusely, like a dead dog, tired and sitting in front of the stone gate and unable to stand up again.

This is a three-meter-high stone door, the surface is blue-gray, there is nothing on the door except a pair of latches, the three of them just look at the whole picture of the stone door, you can feel a strong antique atmosphere coming.

Mu Qingchen looked at the huge stone gate, her eyes were full of brilliance, her delicate and snow-white cheeks became a little red, she didn't have the slightest fear, but she still looked a little excited.

And after Mu Yan saw the whole picture of the stone gate, his pupils shrank, according to his team's understanding of the task, they needed to enter this gate, but the weight of this stone gate, to say the least, was a thousand catties!

Even he couldn't have opened this giant door!

And for whom is this for?

What's inside this door?

Why close it off?

What is the reason for the closure of the seal, but also to apply a layer of stone wall to hide?

Thinking of this, Mu Yan suddenly had a bad premonition in his heart...... as if something dangerous was waiting for him behind the door.
