The road is getting harder and harder, and there are more and more rocks on the ground, but fortunately the cave is so big that we don't have to bend down to avoid it.

Being large in size, this should be one of the weaknesses of the mother.

The terrible sound just now caused a lot of stress in my heart, and this unknown thing was the most terrifying.

The last time I saw the female worm of the white phosphorus insect, it was very large, and according to my speculation, the female insect of the fire phosphorus insect should be similar to the white phosphorus insect, or even more powerful.

And, this time it's a live one!

I haven't seen a living female, but I speculate that it must have a lot of strength, and that's something we should all pay attention to.

I don't know if the mother worm can speak human language. Last time, the leader spoke human words, and although the leader controlled the brains of living people, it was powerful enough.

As I continued to move inside, the water under my feet was already up to my ankles.

"Zhao Jie, have you noticed that there is something wrong with this water?" said Lao Wu with a sudden frown.

Questions?

I took a closer look at the water under my feet and took a closer look at it with a flashlight, but I didn't find anything wrong.

"Don't you think it tastes a little strange here?" continued the old black.

Flavor?

I sniffed it closely, and I did feel a strange smell in the air, which smelled like I was in a chemistry lab.

"What do you mean...... Does this smell come from the water?" I looked at the old black, waiting for his answer.

Lao Hei nodded: "Although I am wearing protective clothing, the smell is obvious, I felt it carefully, this is from the water." ”

Although our protective suit is a glass helmet, there is a layer of barbed wire at the chin for breathing, so it does not affect the identification of odors.

"Could it be this water...... It's all the mother's...... Pee?" said the old black uncertainly.

His statement startled me, if so much water is the urine of the mother, then how big must the mother worm be?

"No, no, no, I have another idea, maybe...... We're in the mother's belly!" I was just startled by him, so I decided to scare him too.

Who knew that Lao Hei was serious about my words: "Zhao Jie, what did you say...... Seems to make sense. ”

I shook my head and said with a smile, "What's the point? I'm just making it up! How can this be in the stomach? We can't be so stupid as to unknowingly get into someone's belly." ”

Lao Hei still looked serious: "Then how do you explain that there is no moss on the stone in front of you? Also, the mysterious man is no longer there, but why haven't we seen the fire phosphor again?"

"Don't scare me, I'm afraid it's impossible, right?" This situation, coupled with Lao Hei's strange tone, I really felt that the air around me was full of terror.

"Go ahead and see. Lao Hei carried a sprayer on his back and walked forward with a flashlight.

It doesn't look like he's teasing me, he should be really thinking about it, but no matter how I think about it, I think it's a bit, we can't get into someone's stomach and don't know it!

As he walked, there was a loud but deep sound from the depths of the cavern, and it was breathtaking.

"Old Hei, listen, the direction from which this voice came should be where the mother worm is, and what you just said is completely impossible. I looked at the old black and said.

Lao Hei still shook his head and said with a serious face: "How can you know that it is not the sound of its digestive tract digesting food?"

"Black, it's not funny at all. Without evidence, let's not think nonsense. I said and walked ahead.

Digging deeper, the water under my feet had reached the calf, and we still hadn't found the female worm, which made me a little confused.

I heard a loud noise just now, and it wasn't far from us, but why didn't we see any creatures after walking for so long?

At this moment, the loud noise came again, and this sound that seemed to come from hell shook my heart. What creeps me even more is that the direction from which the voice came from this time is behind us!

"Lao Hei, this time things are really a little weird!" I looked at Lao Hei with frightened eyes, and his face was not good-looking.

After going through so many things, I thought I was bold enough, but this time I was scared again, this thing is really weird!

"Let's step back and see. "Lao Hei said and took me back, although our physical strength is limited, but this time we can't run.

After walking back for a while, Lao Hei suddenly stopped.

"Old Black, you ......"

"Shh......h Listen!" the old black motioned for me to come closer to the rock wall and listen to the sound.

I listened as he instructed, but it startled me again. The sound coming from behind the rock wall was the loud sound I had just heard, but this time it was many times quieter.

"What the hell is going on?!" I rushed and punched the stone wall.

What surprised me even more was that the stone wall was actually soft!

My feelings at this moment are indescribable, and I can only look at Lao Hei with a very ugly expression: "Lao Hei, we really fucking guessed right!"

"What do you mean?" looked at me with a puzzled expression, and stepped forward to touch the rock wall, and then his expression changed.

I kept reminding myself that this couldn't be the inside of the mother, because no creature would have a body full of stones like a cave.

But I overlooked a lot of important things. First of all, the fire phosphorite is not an ordinary creature, and I can't measure it by an ordinary creature.

Secondly, the food that fire phosphorites eat is not an ordinary food, they feed on energy, so the structure of the body will definitely be different.

Furthermore, I thought of the corpse of the fire phosphorus insect that I saw in the mine cave in Xiayang Village, and the corpse was not normal flesh and blood, but there were various minerals, and these minerals formed part of its flesh and blood.

In addition, chickens also know how to peck sand and grind food, and fire phosphorites have such a high IQ, it is inevitable that they will not use these stones to help digestion or other uses.

"It seems that we fell for the trick from the beginning!" "Do you remember the section of the road full of brown stones that we walked after being rescued by the mysterious man?"

When Lao Hei said this, I suddenly understood: "You mean...... That part of the road is actually the mouth of the mother worm?"

"Hmm. He nodded slightly, "I wonder why not only are the stones brown on that stretch of road, but also the surrounding rock walls, and even more different, the stones there are larger and more prominent. ”

Looking at it this way, that part of the road is simply the mouth and teeth of the mother worm!

I shivered, it was terrifying, and this battle with the mother worm was beyond my imagination.

"What are we going to do?" I asked anxiously.

Now the strong acid on our back may not be able to play a role, because this is the digestive tract of the mother worm, and we may not be afraid of strong acid at all.

"I don't believe it's the outside and the inside. Lao Hei said and took out a knife and chiseled at the "rock wall".

But he was really right, this place is indeed fragile, and Lao Hei finally carved a small hole with all his strength.

"Old Black, change me!" I took the knife from his hand and continued to chisel.

The terrifying sounds that kept coming from the depths of the cavern continued, but we're used to it. Now that the frequency of the sound is noticeably higher, I think it is the mother worm feeling pain and starting to scream.

An hour later, a huge hole was dug out by us.

"Well done!" I high-fived Lao Hei, very happy.

"Let's go!" called out the old black in an imposing voice, and I followed him out of the hole.

Outside the entrance of the cave, we can see various intricate veins, and we can also see huge stone pillars horizontally.

"These stone pillars should be one, and this should be its digestive system!" said the old black.

"I think we can get out as long as we find the outermost layer of skin and spray it with strong acid!" I said happily.

But we weren't happy for long, for I soon found out that the place was so big that we couldn't find a direction, and it was even harder for us to tell that it was its skin.

We only had two barrels of acid, and if we sprayed it wrong, we would never be able to get out.

The inside of the female worm is not so hard, but the outer skin is very special, there is a very strong toughness, and the knife will bounce back when it is pierced, which is what Lao Wu said.

At this moment, a strange thing suddenly rolled in the distance.

"What the hell is this?!" I shouted, running off into the distance.

"This thing came suddenly, and I guess it's probably the phagocytes in the mother worm's body, used to get rid of our two 'viruses'!" said Old Black as he ran.
