When the apocalypse comes, salted fish will only make bubbles

Li Ying and the other two slowly descended on the small black cloud. During this process, they took out high-power flashlights and began to observe the surrounding environment.

The space below was unexpectedly much larger than the hole above, and the space became more spacious as one went down.

It's a bit like an inverted cone with the tip flattened.

However, after descending seventy or eighty meters, there is still a trend of not reaching the bottom.

And it should be due to the effect of the magnetic field, all three of them felt a slight dizziness.

Qu Linqing covered his ears to relieve the flash of tinnitus. He looked around and called a halt at the right time: "No, if we go this deep, we might be in danger. We must stop immediately."

Pei Chonglin immediately asked Li Ying: "How are you?"

Li Ying shook her head gently: "I feel a little dizzy, but it's bearable. We haven't gone deep yet, are we going back before we can see anything clearly?"

They didn't find anything except the dark rock walls, and the answer they wanted was obviously at the bottom of the tiankeng.

Now that we have come this far, it would be a pity to just give up.

Pei Chonglin shone the flashlight straight down, but still found nothing: "I still can't see the bottom. It seems like this is really a bottomless pit."

Qu Linqing also looked at it again and again, and then sighed:

"The deeper we go, the stronger the magnetic field becomes. I don't think it's a bottomless pit. But judging by the depth, it must be at least 200 to 300 meters. We can't bear that depth. Since our bodies are reacting, it means we have already reached the limit of our descent."

Li Ying touched his chin and asked curiously: "But this pit looks so strange, how did it form such a shape?"

It was narrow at the top and wide at the bottom, and surprisingly deep. He suspected that there was another world underneath.

After observing, Qu Linqing made a rough guess: "I guess it should be the effect of some kind of energy wave, just like a volcanic eruption, the energy burst out at the moment of the explosion."

After thinking for a while, he pointed to the surrounding rock formations and expressed his opinion:

"And if you look at the surrounding rock walls, they are not newly formed. This tiankeng must have existed a long time ago. It is probably only because of the collapse that the hole has become larger and exposed."

"I see."

Li Ying nodded, not quite understanding, feeling that the scientist's words were more reliable.

Pei Chonglin looked down again, and finally had to give up the exploration: "Then let's go back!"

The purpose of coming down here is to see what is going on underneath. If it is not an ordinary deep pit, but a center of magnetic field activity that may cause harm to the human body, then there is really no need to continue this exploration.

Moreover, according to his previous speculation, the zombies have a special liking for this place and are gathering here in large numbers.

That means the energy here might have resonated with the crystal cores in the zombies' brains, which is why they were attracted here.

Therefore, no matter what is underground, it is probably not something that humans want to see.

Just imagine, animals mutated to become powerful and bloodthirsty because of it, but what about zombies? !

So many zombies have already forced the remaining humans into a corner. If they are blessed with this energy, how powerful they will become!

By then, will humans still be able to resist?

Thinking of this, Pei Chonglin suddenly felt a sense of fear. If it weren't for Li Ying's supernatural barrier that blocked the zombies outside, the consequences would be disastrous!

If it was really as he guessed, the investigation could indeed be terminated, and they would probably have to do something big again after returning.

Qu Linqing certainly agreed with Pei Chonglin's proposal.

But he didn't want to come here for nothing, so he gently pinched the soft little black cloud and pleaded, "Well, before we go back, I need to collect some soil from the rock wall. Please help me, little black cloud."

Little Black Cloud couldn't speak, so Li Ying, the owner, of course had to speak for him, so he patted his chest and agreed: "No problem!"

Then, he patted Little Black Cloud twice and gave an order: "Little Black Cloud, did you hear me? Let's go back to the edge!"

The sampling work was very simple. Xiao Heiyun followed Qu Linqing's instructions, stopped briefly at several different heights, and then successfully completed the task.

When they came out of the cave again, the dazzling sunlight made them cover their eyes.

It took them a while to adjust to the brightness outside.

Zhu Daneng was lowering his head to catch the rope, and when he looked up, he saw the three people who had gone and returned. He opened his mouth in surprise: "Master Pei, is there something going on down there? You guys retreat quickly, we'll cover you!"

The barrier opened, and the three people jumped down one after another. They looked at each other and couldn't help but smile helplessly.

The situation below is indeed not optimistic, but there is no imminent danger.

Zhu Daneng is too nervous!

Li Ying was the first to speak to comfort him: "Brother Zhu, calm down, everything is fine for now, don't worry!"

Zhu Daneng heaved a sigh of relief when he heard this: "Oh, you scared me. You guys came out so suddenly, I thought something happened!"

At this point, he glanced at the time, and couldn't help but look into the cenote, then asked in confusion, "What's the bottom? It's not that deep!"

Even if you reach the bottom, you still have to look around. It's impossible to get up so quickly!

It was Li Ying who took over and replied: "Wrong, we came up because it was too deep."

Zhu Daneng scratched his head: "Too deep! Really deep?"

But before anyone could answer his question, Pei Chonglin interrupted him: "Okay, now is not the time to study this."

After thinking about it for a while, he came up with a plan: "Zhu Daneng, you are responsible for arranging for everyone nearby to evacuate another five kilometers. No one is allowed to approach without orders!"

"Yes!"

"Also, there's a guy named Song Weide on the other side. Contact him and make the same evacuation arrangements."

Seeing Pei Chonglin made arrangements to stay away from the tiankeng in just a few words, Qu Linqing couldn't help but frowned: "What do you think?"

Pei Chonglin took a deep breath and decided to tell them his guess about zombies: "Xiaoying, Linqing, I have a guess now."

Qu Linqing: "What guess?"

Li Ying looked at him, scratched his nose and urged him: "Yes, if you have any ideas, just speak up. I know you won't make the decision to evacuate without being sure."

Seeing that they were all staring at him seriously, Pei Chonglin began to answer seriously:

"I think we have been misled from the beginning. This may not be the center of the magnetic field at all, but a special energy source. It is precisely because of the existence of this energy source that zombies from all directions have gathered here."

Qu Linqing: "The source of energy!"

Li Ying: "Is this why the zombies are here!?"

Qu Linqing and Li Ying spoke almost in unison, their words were different, but their focus was the same.

Pei Chonglin saw this and made his words clearer: "That's right, their target from the beginning to the end should be this energy source, and we just happened to be in the center of their encirclement!"
