"This tunnel must have been dug freshly. Ming Liang whispered.

The atmosphere was extremely low for a while, and everyone couldn't help but swallow a mouthful of saliva. The four beams of light were slightly intertwined at first, and then spread out in four different directions.

Just when we were all confused, Brother Mingshan was the first to stand up against Mingliang's opinion.

"If this tunnel is newly dug, how can the pit be explained?"

"Huh......" Mingliang gasped, tilted his head and replied in agreement, "Yes, that big pit has obviously existed for some days." ”

"Otherwise, let's move on. Mo Qingyan interjected softly, with some forbearance and some uneasiness in his tone.

While they were still discussing what was going on in this tunnel, Mo Qingyan's eyes kept looking at the road ahead. Although he was silent, I guess he was more anxious than anyone else.

"yes, it's useless for you to discuss that now. I said.

The two brothers, Mingshan and Mingliang, took one look at me and nodded to each other. Then at the same time, the light of the flashlight turned ninety degrees and shone on the perfect tunnel on that side.

"Joan, listen to you, let's go. The two of them said in unison.

So, with a doubtful heart and nervous steps, we stepped into the other half of the tunnel one by one.

The other half of the tunnel, at a glance, you can see that it took a lot of effort to dig out. Although there are no traces of mechanical use in the vicinity, the effect of digging up is the same as that of cutting with those machines.

It's even more "beautiful" than the rest of the tunnels in Lazy Town.

However, perhaps it's because no one has moved around for too long, and there hasn't been ventilation for too long. The dust on the ground must be as thick as a carpet.

So when we stepped inside, the entire tunnel was dusty, and visibility instantly dropped to zero. Not only did he not see his fingers, but even the light of the flashlight could not penetrate the gray dust.

"Everyone hurry up and grab the shoulders of the previous person and don't get separated. Ahem!" shouted Brother Mingshan.

This dust not only obstructs our vision, but also enters our breathing ports. Just taking a small breath is like eating a large mouthful of pepper noodles, and breathing suddenly becomes extremely difficult.

I reached out and poked left and right in the dust before finally putting it on Mingliang's shoulder. And Mo Qingyan, who was behind me, also stretched out his hand and groped carefully.

I looked back and saw that he hadn't been able to put his hand on my shoulder for a long time, so I deliberately slowed down and leaned back slightly. After a few temptations, he finally touched my shoulder, and he couldn't help but breathe a sigh of relief and whispered.

"Thank you, little girl. Ahem!"

Although I couldn't see his face anymore, I was overjoyed to hear him endure the choking dust and thank me solemnly.

"No thanks. I replied politely.

I'm not afraid of this choking dust, because under this mechanical device, I have already put on a nanosuit. When the dust came in, the nanomatter reflexively flooded up on my face, forming a mask that could block out any gas or substance.

I have to say that this Valkyrie nano suit is really smarter and more powerful after being transformed and upgraded by Qin Qin and Gu Chengzi again.

After a little more walking, the air in the whole tunnel got worse. Breathing has become more difficult for them. They all coughed in pain, and their progress slowed down considerably.

"How are you doing?" I asked worriedly.

"It's okay...... Ahem...... There are only a few steps left...... Ahem!" Brother Mingshan coughed, one

Bian replied.

Seeing that Brother Mingshan answered so hard, I immediately regretted asking them. It stands to reason that they should hold their breath right now, but the dust has already entered the device, and no matter how long they hold their breath, they will have to breathe anyway.

And once you can't help breathing, the choking dust will irritate your throat and lungs, making you cough uncomfortably.

I felt bad in my heart, if they continued to cough like this, sooner or later they would have to cough up all their internal organs.

We had to find a way to get rid of the dust, and I told myself that if we couldn't, we'd have to go back, and there was water in half of the tunnel.

That water can adsorb dust and will greatly reduce the concentration of dust.

But...... How long will it take to go back!

The cough was so unpleasant that all three of them stopped and fell to their knees in pain.

"You!" I squatted down beside Mo Qingyan worriedly, and ran my hand down his back in a panic.

"Little girl...... Cough...... Ahem......"

"Mo Qingyan, don't speak. I'll carry you back right away!"

With that, I reached out and ran my hand through the crook of his arm, ready to lift him up. But he waved his hand and squeezed mine.

"Water!cough!gas!cough!cough!" he said with difficulty.

"Water?gas?"

Mo Qingyan coughed so much that he no longer had the strength to reply to me, seeing this situation, I could only rely on myself to figure out what he meant.

Water...... I know that water can attract dust. But the gas ...... What kind of gas is he talking about? Where is the gas here?

I thought about it, but I couldn't figure it out.

At this moment, I suddenly remembered the scene of myself falling from a great height. At that time, Brother Mingshan grabbed my hands, hooked my calves, and forcibly pulled my limbs apart before he could finish counting.

And at that moment, the fumarole on my stomach instantly burst out with a stream of air. This current not only caused me to brake the car, but also immediately changed the direction of my flight.

"By the way, it works!"

I quickly untied the water bag on my body, unscrewed the mouth, and inserted it into the jet port. And with a quick gel, dip the air jet and water bag mouth on.

Then from the tool kit, I took out two thin needles and pierced more than a dozen needles at the bottom of the water bag.

Then, I adjusted the painting system to manual mode, raised my right thumb, and gently pressed the blue button on the side of my index finger, and a strong air flow erupted from the vent.

Fortunately, I adjusted in time, otherwise this water bag would have burst in a blink of an eye.

The air stream squeezes the water in the water bag, which is sprayed out through a pinhole at the bottom. For a moment, it seemed to be raining in the tunnel.

The "rain" gradually made the air in the tunnel damp, and the dust raised gradually absorbed in the water molecules in the air and was carried back to the ground.

I sprinkled around with the water bag in both hands and sprinkled almost half of the water on them, as if I had given them a shower.

The thick, choking air gradually regained its freshness, and the few of them finally stopped coughing so painfully.

Brother Mingshan sat up first, he leaned against the wall, shook his head hard, and took a few deep breaths slowly. Immediately after, Ming Liang and Mo Qingyan also regained their senses, and they leaned together, burying their heads between their thighs tiredly.

"How are you doing? Is it still hard? Or I'll drench it a little longer. ”

I'm so worried about them that I'm willing to spill the water in this water bag.

"No need, Joan!" Brother Mingshan waved his hand, signaling that I didn't need to sprinkle any more water

"But you're still very uncomfortable. ”

"It's okay, let's just take it easy. Mingliang said.

"Yes, little girl, don't waste water, keep it for yourself. Mo Qingyan gasped and nodded affirmatively to me.

As soon as he said that, I pressed the button and turned off the airflow. And take out a knife, separate the quick gel, and cover the mouth of the water bag.

Some people may ask, what about the pinhole at the bottom of the hydration bag?

I really don't need to worry about it, because this water bag was designed with water leakage in mind. It uses a material that repairs itself, so if there are any cracks in it, or if there are these inconspicuous pinholes, it doesn't matter.

It only takes a moment for the pinholes to heal themselves, so I don't have to worry about it leaking.

After resting for a while, their bodies finally regained their strength. Brother Mingshan stood up with difficulty, and after sighing deeply, he pulled up Mingliang and Mo Qingyan, who were sitting on the ground, with both hands.

"You don't have to rest a little longer?" I asked.

"It's better to hurry. Mo Qingyan said in a low voice.

And Brother Mingshan walked to my side after pulling the two of them up. Through his eyes, I seemed to see a kind gaze.

"Joan, thanks to you. Otherwise, we're all going to die here!" he said, holding his back hand to his waist.

"Bah, don't talk about these bad things!"

After packing up again, we continued our journey. Maybe it's because each of us is covered with moisture, and we don't raise any dust on the road, but just leave a pair of damp footprints on the ground.

Their breathing was not so hard anymore, so everyone's steps gradually increased. In the blink of an eye, we have come to the end of the tunnel.

However, the end of this tunnel is like a dead end.

There was not a trace of a secret door except for the bare rocks.

"Let's split up and find a mechanism. Brother Mingshan said.

So, the four of us went our separate ways. I am responsible for slapping the wall on the left, Mo Qingyan is responsible for slapping the right one, Mingliang is responsible for slapping the ground, and Brother Mingshan is responsible for slapping the top of the tunnel.

"Smack...... Smack......"

I carefully slapped the walls and listened carefully to the sounds. They said that if there is a mechanism on the wall, the sound of slapping will be different.

"Smack...... Syllable...... Click...... Click......"

These two "clicks" caught not only my attention, but also all of them. They quickly gathered around me and asked in unison.

"Found it?"

"Perhaps......" I said, pointing to the different sounds.

Brother Mingshan raised his hand and pressed it in with one hand. With a "click", I saw that the place bounced up slightly, and it seemed to be a lid.

Ming Liang lifted the lid with one hand and hit the light straight on it. Only then did we see clearly, and it turned out to be a handle inside.

Ming Liang grabbed the handle and turned it clockwise. There was a "clang" on the top of our ceiling, and a door opened.

One by one, we climbed up and came to a room. There was not a single speck of dust on the floor of this room, and it looked like it was occupied.

I was about to say something when Ming Liang raised his hand, made a closed gesture, and motioned for me to look back. I looked back sharply and realized that there was a man sleeping behind us.

However, he lay in the healing room, as if he was dormant.
