The four of them moved in, and those small electric cars were also transferred in, and with these means of transportation, it was equivalent to jogging in these underground passages, the speed was still okay, and it saved physical energy.

There is a lot of space inside, like an underground world, but the height is only one meter five or six, and they need to lower their heads when they get on a small electric car, otherwise it is easy to hit the top.

It was more than two meters wide, and it was not known what it was used for, so they fired to the left.

The width can accommodate two small electric vehicles walking side by side.

Whew!

The four people driving could clearly feel the flow in the air, and the coolness seemed to be in late autumn and winter, when the weather was extremely cool, and there was no feeling of stuffiness at all.

With great anticipation and apprehension, the four of them drove a small electric car and had been moving forward for more than 20 minutes, and they could even imagine in their minds that they had moved a long distance.

Even if you don't get out of a zone, it's pretty much the same.

With such topography and complex structure, it is no wonder that until now, they have not heard a single sound, as if so many people who entered before have disappeared out of thin air.

It's been a few hours since I've been here, but apart from the four of them, I haven't even found a single figure, not even a single corpse, which is obviously unlikely.

They stopped and rested in place for a while, Li Tianqiang and Chu Lang took out their mobile phones to try to contact, but unfortunately after a few times, they had to give up, and there was indeed no signal.

And Lin Zhen is on the tablet, and there is also no signal source, and the previous navigation map has lost its guiding significance.

They are now groping their way forward in the unknown night, fortunately there are four of them, they can talk and joke with each other, and some nervous emotions are involved, if they come in alone, they are afraid that their confidence has collapsed, and their spirits have all kinds of hallucinations.

This is a very test of people's willpower, and it is also a very confusing space.

The four of them discussed, and each deduced their own position based on the road they had traveled and the location of the space, and finally the four of them compared it, found out the commonalities, and made an estimated approximate location on the tablet navigation map.

With this orientation in place, five or six of these estimated coordinates were marked along the way, forming a set of lines, and they thought that there was still an hour to go before they could reach the core area.

Of course, the premise is that on the basis of going straight ahead, you can reach the core area in one hour.

Lin Zhen and the other four rested for a while and continued to move forward, for their current situation, there was no better choice than to continue to move forward.

Half an hour later, they were stunned.

Along the way, they didn't pass any forks, but in front of them was a wall.

Meaning, they walked for more than an hour and came to the end of this passage.

The expressions of the four of them became a little solemn, and Wang Shi said: "It won't be a solid wall, then we will be a tragedy." ”

The four of them got out of the car, came to the wall reluctantly, and observed, but there was no clue on the walls around them, and they could only take the end of the dagger and keep hitting every huge stone slab on the wall.

A dull sound came, and this desperate response pierced through their hearts and made them feel a little disappointed.

"It won't be so hard!" Wang Shi muttered to himself, constantly tapping on the huge stone slabs.

The four of them scattered and knocked in various positions, and suddenly, I don't know who hit which piece, and the whole wall shook violently.

The vibration under their feet was also very strong, and the four of them quickly retreated in fright, and at this moment, the sound of the friction of the underground machinery sounded, as if the mechanism was starting.

Lin Zhen and the four of them glanced at each other, and then looked at the wall in front of them in unison, and at this time they were slowly moving to the left to open it.

The four of them raised their assault rifles in their hands in unison, and each of them looked ahead with cold eyes.

Especially Lin Zhen and Wang Shi, they were worried that behind this wall, there was a group of mutants, in that case, they would not even have a chance to live.

Rumble!

Click!

The sound of friction and the muffled sound of machinery turning was heard, and the stone walls kept moving and opening, and they also saw the scene on the other side of the passage.

A faint blue glow emanated from within, illuminating the passageway, and they became more vigilant, each raising their assault rifles and staring coldly at the source of the blue light.

They couldn't help but blink their eyes when the light was not too strong, and soon, the stone wall doors all opened, revealing a space with a huge stone chamber inside, and the cliffs around the stone chamber were inlaid with stones that glowed pale blue.

The entire stone chamber space forms a sea of blue.

"What is this ......?"

At the same time, inexplicable questions appeared in the hearts of the four people.

It was the first time they had seen such a scene, and it was very quiet, except for the faint blue glow of the stone, and the stone chamber was empty.

They watched the entrance of the passage for a while, and even leaned sideways to look at it for a while, and found that there were two passages in the stone chamber that were open.

"What should I do?"

Chu Lang said: "What else can I do? If there is a way, go forward, there is no other way back, is there? ”

Wang Shi nodded and said, "What are these glowing stones, I haven't seen them when I'm so big, the rumored Night Pearl?" ”

"I haven't heard of the Blue Light in the Night Pearl, have you?"

"Alien stones?"

"Or is it some chemical glow?"

The four of them discussed with each other, and no one came to a conclusion, mainly because no one had ever seen this thing, and their brains were full of conjectures.

Let's go in, we're already here, and there's no other way out!

As long as there was no danger, they would not flinch, and the four of them hurriedly returned to the small electric car and drove into the stone chamber.

When they entered the stone chamber, they found that the air smelled of mint.

This strange feeling made them secretly surprised.

"Where do these scents come from?"

With the help of the light, the four of them searched for it, but found nothing.

Wang Shi said: "The only explanation is that the stones that glow blue are also emitting a minty fragrance. ”

Li Tianqiang guessed: "Or maybe these blue lights are actually with a mint fragrance." ”

Lin Zhen frowned, observed and said, "No, it should be these mint scents, which can emit light blue light." ”

They quickly turned around, but they didn't find anything else, but they didn't dare to dig up the glowing stone blocks embedded in the walls, for fear of touching the mechanism here, and if they were trapped here, then they could basically GG.

I'm going to be here for the rest of my life.
