A narrow passage less than one meter wide appeared in front of Mo Chen and the others, Mo Chen breathed a sigh of relief, and Dai Min beside him whispered excitedly.

Although no matter how deep the passage is, as far as Mo Chen's eyes can see, he can't see clearly for the time being.

But at least there is a passage in front of us that proves that this method is feasible.

Mo Chen stretched out his hand and pressed hard at the entrance of the cave, the top of the passage was made of gravel and debris overlapping each other, but the hardness was still good.

At least after Mo Chen pulled hard, the debris on the roof of the cave was still stuck with each other.

Mo Chen turned to Dai Min and said, "For now, this passage is safe.

But...... The section inside, whether it is good or not, still needs to be developed a second time, and once again experience tremors, what will the top of the cave look like, I can't say. ”

Dai Min waved her hand, interrupting Mo Chen's words, she sighed and said, "Alas......

Although you said that Fan Tong would come to save us, we have no way of knowing if they have encountered thorny problems themselves.

Even if they are in a hurry to rescue us at the moment, even we ourselves are not sure where we are in the ground now.

Other emergencies aside, it is uncertain how long the air we depend on will be enough to sustain us.

So, I ......"

Dai Min paused when he said this, looking at Mo Chen's eyes, flashing with an irrepressible desire to survive.

Mo Chen said, "Okay, since you have decided, then give him a go." ”

This is a game with half the probability of death, but as Dai Min said, at least there is still a slight chance that they can survive.

Mo Chen is very happy, the clear-minded and analytical Dai Min is back, she is not crying, she is brave to face the predicament in front of her.

Then, Mo Chen took the lead, and Dai Min followed closely behind him.

Following the excavated hole, the two of them had not gone far before the hole was short again.

The passage dug by the two ended here, and was replaced by a blockage of rubble.

Although there is an inconspicuous small hole, Mo Chen can faintly feel the wind passing by, but the small entrance of the cave is speechless.

If the previous entrance can still be described as a dog hole, then this time the entrance of the cave, Mo Chen really wants to call it a mouse hole.

Mo Chen and the two only exchanged one look, and Mo Chen repeated his old trick and started the second blasting.

All the tragic endings that may arise, Mo Chen has already imagined many times in his mind.

He took a deep breath, his arm up and down, followed by another thud.

But the dust in front of them dispersed again, and both of them breathed a sigh of relief and smiled at each other.

In this way, every time he walked for a long time, Mo Chen needed to do a "blasting".

Although, there were two times along the way, and they almost collapsed, so that the two of them were buried alive.

However, because of the actual "blasting" along the way, Mo Chen quickly accumulated experience.

Or, their lives should not be extinguished, and the two almost collapsed were resolved by Mo Chen in time.

In this way, they stop and go, making "noise" and dust.

Until there is no road in front of them, and there is no wind-blowing hole to leave them with a way out, but......

Mo Chen and the others looked at each other, all staring at the "guys" who blocked their way.

This place is underground, and Mo Chen and his people can see ruins and garbage formed by the collapse of some houses.

But at this time, the obstacle in front of them was different, it was as tight as a wall, and it was impervious to the slightest wind.

Moreover, it is not the first time it has appeared in front of Mo Chen, because it is the iron door that Mo Chen and his followers are looking at on the "road" to save Dai Min.

On this iron door, strange patterns are depicted, and the outlined lines seem to be some kind of alien script.

Mo Chen stared at the iron door and said to Dai Min, "It seems that we have encountered a new problem. ”

"Hmm." Dai Min responded, and at this time, her attention was all attracted by the strange lines carved on the door.

Dai Min looked at it for a while, tilted his head and said to Mo Chen, "Don't you think the lines on this door are particularly strange?" ”

When Mo Chen saw those patterns for the first time, he had a hunch, as if there were hidden clues in those patterns.

It feels ...... It's like encountering a puzzle, and the lines on the door are the surface.

As long as you can understand all kinds of details, you can solve the puzzle easily, and when the puzzle is solved, the door will definitely be opened.

Mo Chen pointed to the center of the iron gate and gestured and said, "Well, it's quite strange.

For example......" Mo Chen raised his hand and pointed to the middle of the door, as well as its four corners.

Mo Chen continued, "You see, this piece in the center of the door is surrounded by a pattern similar to rattan thread.

If you stand a little further back, you can vaguely see that the pattern of this part is like a microcosm of the overall pattern of this door. ”

Dai Min took a step back according to what Mo Chen said, Mo Chen stretched out his hand in the central area, pointed to the four positions, and pointed to the four corners of the iron gate.

Dai Min's eyes lit up, she nodded yes, and then said, "If I really tell you a glance, then this pattern in the door is likely to be a hint, and maybe."

So ...... then"

Dai Min didn't finish speaking, he immediately leaned under the door, and reached out to touch the position in the upper right corner of the iron door.

Where Dai Min's fingers touched, there were many patterns carved that they didn't recognize, and it looked like some kind of writing.

After Dai Min's fingertips touched the "text", his wrist was forced, and his fingertips pressed it.

Unexpectedly, the "text" was pressed, like a doorbell, and it fell into the door.

And as soon as Dai Min let go, it bounced out again, and Dai Min turned around and looked at Mo Chen excitedly.

Mo Chen was stunned, and then, he pressed those "words" at the four corners of the iron gate one by one.

Unexpectedly, those "words" were pressed smoothly, and the feeling of pressing made Mo Chen can't help but think of the feeling of his fingers pressing on a mechanical keyboard.

In this way, the two are even more sure that those "words" are the mechanism that opens the iron door.

It's just that Mo Chen doesn't have a clue about this "password" for the time being, but what is certain is that the pattern that Mo Chen pointed to in the door must have something to do with the "password".

The atmosphere suddenly became quiet again, because Mo Chen and Dai Min were all studying what the "password" was.

Mo Chen noticed that the four corners of the central pattern were also painted with "words", but the words were different from the words at the four corners of the gate.

In addition, the four corners of the gate seem to be four, or five characters with a pen, but the four corners of the central pattern are no more than two, and there is even a place in the lower right corner, and there is only one text.
