A 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 exclaimed in excitement.

Even though Mo Chen's eyes could not see clearly even in the deepest passage.

But at least the passage in front of you proves that this method is feasible.

Mo Chen reached out 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 it hard, the debris on the top of the cave were still stuck tightly with each other.

Mo Chen turned to Dai Min and said, "At present, this channel is safe.

However... the section inside may need to be explored again. After experiencing tremors again, I can't say what the top of the cave will look like."

Dai Min waved her hand and interrupted Mo Chen. She sighed and said, "Oh...

Although you said Fan Tong and the others would come to save us, we have no way of knowing whether they have encountered difficult problems.

Even if they are anxious to rescue us at this moment, even we ourselves are not sure where we are underground.

Not to mention other emergencies, it is impossible to determine how long it takes for us to survive alone.

So, I…”

Dai Min paused for a moment when he said this, and looked at Mo Chen's gaze with an uncontrollable desire to survive.

Mo Chen said, "Okay, since you have decided, then let's take a try."

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

Mo Chen was very happy that Dai Min, who was clear-headed and good at analytical, was back. She was no longer crying and bravely facing the dilemma in front of her.

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

Following the digging hole, the two of them walked not far away and then they were the short hole again.

The passage dug by the two of them ended here, and was replaced by the blockage of gravel and mess.

Although there was an inconspicuous small hole, Mo Chen could faintly feel the wind passing by, but the hole was so small that it was speechless.

If the previous entrance could be described as a dog hole, then Mo Chen really wanted to call it a mouse hole for this cave.

Mo Chen and the other two met only one look, and Mo Chen used the same trick again and started the second explosion.

Mo Chen had already imagined all the tragic endings that might appear many times in his mind.

He took a deep breath, raised his arms and fell, and then another bang.

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

In this way, Mo Chen needed to make a "blast" every time he walked for a short time.

Although, there were two times in the middle, almost causing a landslide, causing them to be buried alive.

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

Or rather, their lives should not be lost, and those two almost landslides were resolved by Mo Chen in time.

In this way, they walked and stopped, creating "noise" and dust.

Until there was no road in front of me, and there was no air blowing hole left for them a way out, but...

Mo Chen and the others looked at each other in silence, staring at the "guy" who blocked their way.

This place is located underground, and Mo Chen and others can see everywhere in ruins and garbage formed after the collapse of houses.

But at this time, the obstacles in front of them were different. They were as tight as a wall, and they were not exposed to the slightest wind.

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

This iron door carved with strange patterns and outlined patterns, which seemed to be some kind of alien text.

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

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

Dai Min looked at it for a while, tilted his head and said to Mo Chen, "Do you think the patterns on this door are particularly strange?"

When Mo Chen first saw those patterns, he had a premonition, as if clues were hidden in those patterns.

This feels...it's like encountering a puzzle, and the lines on the door are the topic.

As long as you can understand various details, you can solve the puzzle easily. When the puzzle is solved, the door will definitely be opened.

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

For example…” Mo Chen raised his hand and pointed to the middle of the door and its four corners respectively.

Mo Chen continued, "Look, this part in the center of the door is surrounded by a graphic similar to a vine line.

If you stand a little behind, you can vaguely see that the pattern in this part is like a microcosm of the overall pattern of this door."

Dai Min took a step back as Mo Chen said. Mo Chen reached out to the center area, pointed to four positions, and pointed to the four corners of the iron gate respectively.

Dai Min's eyes lit up, she nodded and said, "If you really tell me about it, then the pattern in this door may be a reminder, maybe.

Then…”

Before Dai Min finished speaking, he immediately came to the door and reached out to touch it at the upper right corner of the iron door.

Where Dai Min touched his finger, there were many patterns that they did not recognize, which looked like some kind of text.

After Dai Min's fingertips touched the "text", he pressed his wrist with force and pressed his fingertips.

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

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

Mo Chen was stunned, and then he pressed the "text" one by one in the four corners of the iron gate one by one.

As expected, the "text" were pressed smoothly. The feeling of pressing Mo Chen couldn't help but think of the feeling of pressing his finger on the mechanical keyboard.

In this way, the two of them became more certain that those "words" were the mechanisms that opened the iron gate.

But Mo Chen has no idea about this "password", but what is certain is that the pattern Mo Chen pointed to in the door must be related to the "password".

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

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

In addition, the four corners of the gate seem to be four, or five characters in a continuous stroke, but the four corners of the central pattern are at most two, and there is even a position in the lower right corner, with only one character.
