Lin Feng inspected the volcanic rock, and there was a high temperature of more than 600 degrees, no wonder these dragon eggs would burst.

It seems that they have just left the hollow into the sea above, mated, and then laid their eggs on volcanic rock, using its heat to hatch.

It may be due to the change in temperature that not a single dragon egg survives, which may also be the reason why there are no small six-clawed Arowana.

It's really irresponsible parents, fortunately he caught some in advance, otherwise I don't know what year and month the next spawning of these two big Arowana will be.

At the bottom of the cave, there was no use value, so Lin Feng manipulated the submersible and floated along one side of the cave wall. When I returned to the depth of 14,000 meters, I saw another strange sight.

Countless small two-clawed Arowana swim quietly in this water, their scales reflecting the fluorescence on the cave walls, making the entire cavity like a galaxy.

He turned off all the lights in the submersible, and the "starlight" outside suddenly became even brighter, making him feel as if he was in an endless starry sky. Occasionally, you can see two large Arowana figures swimming by, like two ribbons that exude brilliance, so soft and free.

He was curious about what the two big guys ate, after all, the body is so big, and the energy they need every day is not a little. So he decided to take a moment to observe, after all, this is a rare occurrence, and he doesn't know if they will be there next time.

After waiting for more than an hour, two big Arowana got into the stone wall of the hollow, it turned out that there was a huge cave hidden there, and countless small Arowana seemed to hear the horn of departure, and followed one after another.

Lin Feng followed the mighty team, and judging from the map, they were heading in the direction of the south. After more than two hours of travel, I finally came to a deep trench, 9,000 meters deep, which should be the Puerto Rican Trench.

This time, the school of cologins did not set off a submarine tornado, but went straight to the surface of the sea, led by two big guys, frantically preying on all the fish they encountered, and almost no fish were spared.

Their speed far exceeded that of ordinary fish, with sharp teeth and front claws, Lin Feng saw a group of small corowa fish surround the shark that had been five or six meters long, and even the skeleton was gnawed clean.

Miraculously, there seemed to be a special connection between these coarowanes, and Lin Feng didn't notice that any of them were left behind, nor did any of them run around.

Like a well-disciplined army, and swift as the wind, I am afraid that human submarines will encounter them and only flee for their lives.

After some predation, the two large Arowana began to swim back and eventually disappeared into the depths of the deep trench.

Lin Feng didn't continue to keep up, these ancient dragon fish have not been discovered by humans until now, and they are very rare and magical, he felt that it was best not to bother too much before studying them carefully.

Before the school of fish disappeared, he caught a few more and packed them in a dozen small jars.

Now that his location is close to Puerto Rico, the southernmost part of Bermuda, he must return to the center and continue his search for Time Crystal ore.

After wandering aimlessly northward for an hour, the submersible suddenly received an intermittent signal, which translated, an ancient distress signal, which originated not at the surface of the sea, but at the deep bottom of the sea.

Could it be that new ships were shipwrecked?

Lin Feng rushed towards the source of the signal, but in the deep darkness of the seabed, he did not find any wrecks.

But the signal, though intermittent, has always existed and has not disappeared.

Somewhat odd, he drove the TBM into the ocean floor to probe the terrain, and a thick fog-like object appeared on the monitoring screen.

Found it, the same thing as the undetectable terrain inside the big ears, and it's likely to be the Time Crystal Mine.

And this time the range is huge, at least 50 times more than the last time. It's no wonder that it can stir up trouble in such a large area of the sea as Bermuda, and it turns out that there are so many time crystals hidden.

Mine, there's nothing to be embarrassed about.

He put out the ore smelter and set the mining route.

This time, he learned wisely, and directly drove the submersible to hide outside the Bermuda area, and then started the ore smelter remotely and began to work.

According to the set route, it took three days and three nights to mine the ore, and he hunted sea life everywhere on the surrounding seabed until the submersible's warehouse was full.

Ever since the ore smelter began working, Lin Feng had lost contact with it, and by the time the signal was restored again, it was already five days later.

Coming to that sea area again, the previous distress signal had disappeared, and Lin Feng concluded that the signal was trapped in the repetitive time and space caused by the Time Crystal Mine Camp, so it would continue to be repeated for an unknown number of years.

I don't know what year the ship or the plane was shipwrecked here, but judging from the radio waves, it shouldn't be too long.

After the exploration of the shield machine, there is no time crystal ore around, and according to the records of the ore smelter, this large ore has extracted a total of 23.1 kilograms of time crystals, which is 60 times that of the big ear.

2,310 super power plants can be built, Lin Feng feels that this time the harvest is not small, and it is not an exaggeration to say that it was smooth sailing without any accidents.

Just as he was packing up his things and preparing to leave, there was a deafening rumbling sound, the bottom of the sea shook violently, the hill collapsed, the ground cracked a huge gap, and countless bubbles surged out of the cracks, like a pot of boiling water.

Submarine earthquake!

I just said that I was lucky, and this kind of thing happened.

Those bubbles made Lin Feng frown, they were not ordinary bubbles, but a large amount of biogas. On the submersible's monitoring screen, countless fish that did not have time to escape quickly lost their ability to move and then died after encountering these bubbles.

This biogas will continue to rise to the surface of the sea and melt into the atmosphere, and if lightning falls near the surface of the sea, or if the temperature is high enough, it will cause an explosion on the surface of the sea, forming a sea of fire.

However, there is no such legend in history as a fire on the sea, and perhaps the people who saw it were already dead, and it was impossible to pass on such a legendary picture.

The earthquake lasted for three or four minutes, and the terrain of the entire seabed had been completely changed, and the surviving underwater creatures hid in terror in the small crevices.

Lin Feng drove the submersible to check it, but did not find the wreckage of the ship or plane that sent out the distress call.

"Didi, found traces of artificial buildings. ”

Lin Feng was a little stunned at that time, this is a 6,000-meter deep sea, how can there be artificial buildings?

But what was shown on the screen made him have to believe the facts in front of him.

In a large crack, a pyramid-like structure with four bottom edges and a square top that resembles the Mayan pyramids.

But it's smooth on the outside and has no steps.

This mysterious pyramid was previously hidden beneath or surrounded by the Temporal Crystal ore, so it had not been discovered by the TBM before.

It was only the violent earthquake just now that it emerged from the deep ground.
