"Noticed, some of the stones are beautiful!"

By the moonlight and torches, we could barely see the material of these stones, and they were indeed beautiful.

From the foot of the mountain upwards, the stones are constantly changing, with the general sedimentary rock underneath, and the stones becoming crystal clear above the bottom.

"Do you know what kind of stone it is? ore or what kind of gem?" she continued.

"In my opinion, this is apatite!" Uncle Wang said at this time.

"Apatite?"

"It's an ore, you see, it's this kind of stone. ”

Uncle Wang said as he picked up a small stone and shook it in front of me.

"Apatite is an important raw material for the production of phosphorus, but I didn't expect this to be a mine!" Uncle Wang said, looking up in the direction of the top of the mountain.

Apatite, fire phosphorite, both have the word phosphorus, and the fire phosphorite just cross-cut this mountain, there should be some connection between this, right?

This problem can only be further known when we climb to the top of the mountain.

After another ten minutes of climbing, we finally arrived.

Rather than the top of the mountain, it is better to call it halfway up the mountain, because this was the halfway point of the whole mountain before.

The situation at the top of the mountain is completely different from what I thought.

I thought it would be a steep slope or a flat top with potholes, but there was only one big hole at the top.

The cave is about 20 meters in diameter and leads to the interior of the mountain, like the entrance to hell.

"Let's climb down!"

I looked at the walls of the big cave, and the walls of the cave were not vertically downward, but a slope.

This slope is inlaid with a lot of stones, large and small. We can climb down with this!

No one objected, and we all climbed down tacitly.

I untied a long strip of cloth from my waist and brought a thick stick to tie it up, which was our spare torch.

After ten minutes of climbing down the cave wall, the slope has slowly become gentle.

"Zhao Jie, look at these stones, they are even more peculiar than what we see outside. Guan Zixuan looked at the stones on the cave wall and said.

I also noticed that these stones have small crystals on the surface, and the color changes when the torch shines on it, which is really peculiar.

Discoloration, which reminds me of fire phosphors again.

Although the stones only change color due to heat, I unconsciously associate the two.

After ten minutes of walking inside, we didn't find anything except the peculiar stones.

Just as we were about to leave, my eyes seemed to catch a glimpse of something.

I hurried to look back.

Any clue is important to me.

Really!

I found something in a bifurcated hole.

It's just something like this, but it makes me nervous - it's a zombie!

"Quick! Get out!"

I whispered, pulling out the cocoon, trying to go back.

"Xiaojie, don't move. At this time, Uncle Wang suddenly said something in my ear.

"Have you noticed that these zombies haven't moved?" Uncle Wang continued.

Didn't move?

It seems to be!

But why don't they move?

Shouldn't they see us attacking?

Could it be that they are dormant?

I told them about this speculation, and they thought it was very likely.

If it has begun to get cold today, could it be that the fire phosphorite will also hibernate?

If they need to hibernate, at least let us escape during this time, and then figure out a way to get rid of them!

"Zixuan, among these zombies, are there any people you know?"

I asked, carefully observing the features of the zombie's surface.

"I don't seem to have seen any of these people, I guess they are villagers from Xiayang Village. ”

"Did you find anything strange about these corpses?" I asked.

"Strange place? You mean they don't rot?"

I nodded.

"I found out about this a long time ago, my father has been dead for half a year, and he is still the same as when he died!"

I turned my head to look at her, and my heart was a little complicated for a moment.

"Come and see!"

At this time, Uncle Wang suddenly shouted.

Without further ado, let's immediately go over to see Uncle Wang's discovery.

"It's ......"

We all stared at what was in front of us.

At this time, on a stone in front of us, there were several thumb-sized bugs.

This bug has a very special appearance, with a thick shell on its back and a red body.

There was a small slit in their shell, and I noticed that the back of one of the bugs was open, revealing the black flesh inside.

There seems to be some white substance mixed in with this black, I don't know what it is.

"Do you think it's possible that the fire phosphorus worms eat minerals?" Guan Zixuan asked suddenly.

"No way to eat minerals! No creature will eat minerals directly. I immediately rejected her claims.

"Don't rush to deny, I mean, will they need these mines to stay alive?"

"What do you mean?" I wondered.

"Even if this mine doesn't provide them with nutrients, what good will it do them if they can't keep it, maybe they can't do without this mine!"

Guan Zixuan's explanation also has some truth.

However, it is unlikely that you will eat minerals.

Wait a minute...... Eating minerals?

"Zixuan, do you remember when we were in Zhongyang Village, you said that they were afraid of the midday sun?"

It seemed to me that something had occurred to me.

"Remember, what's wrong?"

"Isn't it strange to you? They are not afraid of the heat, and can even climb from the chimney into the basement, but they are afraid of the midday sun?"

"That's right!" Guan Zixuan clapped her palm, "Why is that? You must have an answer, right?"

I do have a possible answer.

"Look at the bug, there's a layer of white stuff in its flesh. I pointed to the bug with its back already open.

"If I'm not mistaken, this thing should be white phosphorus!" I said excitedly.

"White phosphorus?"

"Yes, I guess the fire phosphorus insect body should have some kind of special function, which can turn the minerals it eats into white phosphorus and excrete it from the body!"

I'm so happy at this moment, I feel like I've solved a big question!

"It's a bold assumption!" Uncle Wang interjected.

"It's not entirely hypothetical, you think, why don't they dare to face the strong sun?

"Also, you've noticed that the back of the fire phosphorus insect can be opened, and perhaps they open their back at noon every day to remove white phosphorus from their bodies. ”

"That's why they don't dare to come out when the sun is strong, because they're afraid of being burned to death!"

White phosphorus has a low ignition point, and it is easy to burn when exposed to the sun in hot weather, which is why they dare not face the midday sun!

"Since the ignition point of white phosphorus is low, why aren't they afraid of fire?" Uncle Wang asked again.

"Because the thick shell on their backs blocks the flesh inside, they are not afraid of the heat. Am I right? Zhao Jie. ”

I nodded, Guan Zixuan was right.

According to my understanding, the shell on the back of the fire phosphorite should be opened regularly, just around twelve to two o'clock every day.

It's their biological clock.

In this way, one of the major doubts in my mind was solved.

No matter what the fire phosphora eats, it will need phosphorus-containing minerals, which also gives me a sigh of relief, at least they still have a soft underbelly to survive.

Just thinking about it, Guan Zixuan suddenly knocked on my shoulder.

"What's wrong?" I asked subconsciously.

"Zhao Jie, look at these stones on the top!"

Noticing the change in her tone, I quickly came back to my senses and looked at the top.

There was obviously a hint of panic in her tone just now!

"If you look closely, are the crystals on the surface of these stones moving?"

I looked in the direction she was pointing, and sure enough, the small crystals attached to the surface of the stone were moving!

"Shh......h Listen!"

Uncle Wang suddenly made a quiet gesture at us.

After the silence fell, a familiar rustle sounded all around.

My hand subconsciously reached into my pocket and pulled out the cocoon again.

The moment I pulled out the cocoons, the bugs were silent, and the rustling around me slowly stopped.

Just when we thought everything was fine, the zombies on the side suddenly moved!

Damn it!

It turns out that it's not the zombies that are dormant, it's just that the bugs that control them have temporarily left their bodies!

This time the zombie's action is significantly faster!

In the past, their movements were somewhat mechanical, but now they are getting closer and closer to normal people.

If left unchecked, one day they will outperform humans!

I don't know what the bugs are up to, none of these corpses will rot, it's horrible!

A large number of zombies are chasing after the three of us, and we can only keep running!

We started to climb all the way, following the way we came, but the speed up was much faster than when we came down!

I climbed out of the cave first.

Then came Uncle Wang.

We met Guan Zixuan outside the cave, and she was only one step away.

But at this moment, the cave suddenly collapsed!

It's a slope, and the cave is collapsing, and stones are falling down and hitting the slope.

At this time, Guan Zixuan's situation is very dangerous!

"Zixuan, hurry!"
