In the process of searching for the blue hole, Ren Zhen chattered endlessly.

Lin ranched his eyebrows, and a sense of restlessness arose in his heart, feeling that Ren Zhen had gone mad.

Seeing that Lin Chao didn't respond, Ren Zhen changed to a fast and sharp male voice.

You can go to the jungles of Uganda and play sumo wrestling with mountain gorillas, and you may be able to clear your mind under the fierce slap slap. ”

Lin Lan couldn't help but speak.

"That's enough, even if you don't change your voice all the time, and don't quarrel with yourself. I'm exploring mysteries like a real scientist now, how can I concentrate on you making such a fuss. ”

A resentful female voice appeared.

"Alas, yesterday I called people sweet, but today I suspect people to be noisy. ”

Lin Chao's facial muscles twitched constantly.

Hell, is this how language fu is used!

He rolled his eyes and responded: "Ren Zhen, in fact, you don't know, I can block your voice." ”

In fact, he can't block it, and the communication between the two Rao is in his mind.

But even if she can block him, she won't block it, Ren Zhen's sensing ability is stronger than him, and she senses it first when she encounters danger.

And her combat effectiveness is so strong, she is an indispensable partner, and it is important to maintain communication at all times.

But Ren Zhen didn't know that.

Then Lin pretended to make a few gestures and read the words.

"Well, from now on I can't hear anything from you, only you can hear me. ”

A serious Lin Chao grabbed the reef and went upstream.

After communicating at the Saint-Lehong Station and reading the materials in the library, Lin Chao found the Blue Cave and confirmed his guess from the arming outside the Blue Hole.

Theoretically, the Blue Cave was an enclosed space, and he didn't want to bother finding other entrances and exits, so he sneaked in directly from above.

Sure enough, Ren Zhen, who continued to talk awkwardly in different ways, couldn't play alone, and gradually quieted down.

Lin Chao was secretly happy, and sighed in his heart.

If you continue to play like this, Ren Zhen will be schizophrenic and will first kill him.

Ren was so cute in the past that he decided not to talk to her casually again.

As two people who are connected by heart, Lin Lan suddenly felt Ren Zhen's loss, and felt unreasonable, why do you like words so much, even if you like words, you don't have to change your tricks.

If Lin Chao had children, he might be able to understand Ren Zhen's current situation.

Ren Zhen has been in a baby for less than two years now, and her language is almost like a baby's babbling, maintaining a fresh sense of the world and full of curiosity.

But Lin Chao couldn't stand her noise, and Ren Zhen was not an ordinary child, so he wouldn't use crying to make others compromise, so he could only choose to be silent.

The patrol boats were all on the periphery of the Blue Hole, and Lin Chao came to the opposite direction of the sea outpost, which was not easy to detect at a distance of several hundred meters.

Even if anyone could see it, they would only see a fish-like creature burrowing into the blue hole.

It's not uncommon, but who would dive in a blue hole for a fish?

Soon dived to a position of 50 meters, Lin Ran, took off the fish-type camouflage.

Adjust your breathing, control your neutral buoyancy, and hover over this position to soothe your ups and downs.

Of course, he will not be nervous because of diving into the blue hole, but he has expectations, and there are unknown possibilities.

Looking down, it was still a misty and dark, as if there was no end, full of temptation to continue diving.

Looking up, the crystalline bubbles stirred the faint yellow-green light overhead.

Lin Chao: "Let's each explore one side." ”

Ren Zhen didn't speak, and silently went in the opposite direction.

Lin Lan looked at her figure suspiciously, feeling that she was unhappy.

In the past, she would have similar emotions every time a request was not met, but it would soon change.

There are a lot of stalactites and coral reefs in the Blue Grotto, which is indeed a good place for diving.

However, Lin Chao was not in the mood to enjoy the beautiful scenery, so he went all the way down.

There is a discovery!

After 150 meters of depth, the surrounding area was pitch black, and through the strong light of the searchlight, Lin Chao saw a flat spot in the reef.

The coral reef should be formed with potholes and strange shapes, how can it be flat like an airport?

After approaching, the forest was chaotic, and it was cement.

It turns out that the Saint-Le-Blue Cave has a channel to connect to the seawater, but it is artificially closed.

Lin Chao felt that he could already have a clear answer, there must be something hidden in this.

He continued.

All the way to the bottom of the cave, the exact depth is 476 meters, and it was also found that the cement sealed the bottom, covering an area of hundreds of square meters.

Ren Zhen turned into a starfish and leaned over quickly.

"Found it. ”

Lin Lan looked worriedly, her mood was stable, but she was worried that she would babble and imitate others.

At the bottom of the Blue Grotto, there is a cylindrical concrete building stuck in the reef, about 20 meters in diameter.

Lin Chao groped around, and the cylinder was already integrated with the reef, and there were no gaps up and down.

He tried to push hard, but nothing loosened.

sighed: "It's too cautious and too expensive to seal such a little spent fuel with so much reinforced concrete." ”

"If you're cautious enough, how did you get in?"

Ren Zhen's complaint made Lin speechless.

He pulled out his hammer and chisel and began the tedious process of drilling.

Dingdingding......

It's not easy to exert force on the bottom of the sea, but Lin Chao still hits the chisel accurately every time.

As he dug day and night, the cement blocks on the outside began to fall off.

"Haha, drilling wood for fire has opened the era of human civilization, and now I can understand the hardships of Gu Rao by taking the core of diamonds. ”

Ren Zhen: "Obviously, the emergence of writing is the beginning of civilization. ”

Lin raised the bar, "I think it's fire." ”

"Don't knock, let me do it. ”

"No, it's not good if you're irradiated. ”

Lin Chao looks like I'm good for you.

Ren Zhen was unmoved.

"Cut, I just can't bear to give me anger. ”

Lin Chao's mind was seen through by Ren Zhen, and he laughed dryly twice and continued to beat.

Ren Zhen has never understood the existence of the universe, anyway, Lin Chao can take things out at any time and then make things disappear, and he never explains.

She looked at Lin Chao with the spirit diamond head at the tip of the horns.

Finally arrived at the place where it was passed, Ren Zhen looked at the hole with a diameter of five centimeters, and he didn't know why.

She went in and looked around, and inside was a metal cylinder, which was the easiest to deal with against Lin Chaolai metal.

"If you want to go in, you'll have to drill, do you have so much time, it's been a week. ”

"No, you drip it on it. ”

Lin Chao calmly took out an eyedrop-like squeeze bottle, which contained a high-concentration corrosive liquid.

Ren Zhen complied, and after opening a hole in the metal shell, there were dozens of metal pipes inside.

"What else to do?"

"Come out. ”

When Ren Zhen came out, he found Lin Chao pressing one hand on the hole and asked, "That's it?"

"That's all. ”

Lin Chao's left hand was heating up, already absorbing those distorted nuclear elements.

His satisfied expression gave Ren Zhen a full view.

"Can I level up?"

"It's hard, it's too little. ”

Ren Zhen's expression darkened, and he turned into a sea creature and wandered around again.
