The dark deep sea is strange and unpredictable, and the circle of life collapses.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

"Lanxing's biosphere is still too narrow......"

At the bottom of the dark and lightless ocean, on the bare rock bed, a small figure walked slowly.

One meter four tall, long sky-blue hair dancing in the water, a pure black diving suit made the girl almost completely into the dark environment, and her blood-red eyes sparkled in the dark.

…… Is this playing the vampire of the night?

"I don't know what kind of strange setting it is based on, but blood-red eyes are indeed better suited for infrared detection." The cavity of her body was filled with seawater, which increased the density and allowed her to walk steadily on the bottom of the ocean, and the water pressure of the sea was ...... The body can still afford that little bit of gas.

Stomp ......

In the deep sea of prehistoric times, the sound of footsteps spread in the sea, but it did not cause much commotion, because ...... It's too deep here.

"Depth Gauge Measurement...... Current depth: 8,774 meters below sea level. ”

Xinglan raised her blood-red eyes and looked up, and the infrared vision was only reflected by the infinitely dark seawater, and there was no trace of life at all. The rock bed beneath your feet was also bare, and it seemed to be completely dead and silent.

It's too deep for sea giants, whales, and bone squid, and shallow sea creatures will only be crushed to pieces by the huge water pressure when they come here! Therefore, there does not seem to be any life here...... Of course, this is impossible.

"Never, never underestimate the potential of life." Xinglan muttered to herself as she bent down and pinpointed a ...... from the loose sand Shrimp?

Indeed, shrimp is a creature that is very well suited to living in the deep sea...... As for food, their consumption is also very small.

"But the density of living things is too small...... Xinglan raised her left hand, which was still intact, and opened the luminous element in her palm, and a bright white pillar of light instantly pierced the darkness here, and the end of the pillar of light disappeared into the infinitely distant deep sea......

At the bottom of the sea, heavy snow is falling.

Gently catch a few falling pieces of white debris, some of which are the excrement of animals above or the shredded corpses of dead creatures, but for the creatures of the seabed, they mean only one thing: food.

Undercurrents swell in the ocean floor, blowing snowflakes like the wind, but there are too few organic debris to meet the needs of life on the seabed. Therefore, although there are organisms here, the density of organisms is very low.

Xinglan is looking for the real thriving area of life on the seabed step by step.

……

The equatorial regions tend to have the highest biodiversity on a planet, but don't assume that the polar regions are scarce. In fact, the low number of organisms in the polar regions will indeed slow down the growth rate due to low temperatures, but because of the seasonal convection of the ocean, these mineral-rich seawater will bring rich nutrients to the polar regions, which can cause organisms to multiply, and eventually the number of organisms in the polar regions is quite large!

Unfortunately, Xinglan can't see the true polar ecosystem yet. The global temperature of Lanxing is now high, and it is clear from space that there is almost no ice cover in the polar regions, and don't forget, the Panpaleo continent is still one, and there is no polar continent at all.

Xinglan walked on the bottom of the sea while thinking about the future of Lanxing.

"Either way, the polar ecosystem has to exist." In the signal subnetwork, countless messages are being calculated frantically, and the girl seems to be pondering, but her pace has not slowed down at all, "To reduce the global average temperature, we still need to divide the continent...... There's a way to do it all! However, it will take another hundred years because this is my ...... Promise. ”

"The one who will come in the end ...... 'Joan.'"

Grunt...... Grunt......

The sound of a series of bubbles was not loud, but it was particularly noticeable in the silence of the deep sea.

"Sulphide levels are on the rise." After casually testing the seawater, Xinglan was in a good mood, "It seems that this is around here." ”

The auditory sensor is turned on to the highest accuracy, and it is fully committed to tracking the source of the sound. Xinglan also turned on the light-emitting element on her forehead, as if she was wearing a headlamp, running forward in the dark waters......

With the infrared sensor turned off, a snow-white pillar of light pierced through the darkness and illuminated the seabed ahead, and more small creatures such as shrimp and crabs gradually appeared on the bare rocks.

Grunt...... Grunt......

The bubbles grew louder and louder, and finally, as Xinglan circled a small hill under the sea, a tall column of black smoke appeared in front of her.

"Found you, hydrothermal springs, black chimneys underwater."

……

The planet's earth is littered with countless tiny fissures, not only on land, but also at the bottom of the ocean.

These tiny cracks in the earth's crust under the action of pressure will eject the material inside the planet outward, although it is not as violent as a volcano, but it is indeed the material inside the planet, so the type is very close to the material ejected by the volcano.

A variety of elements that are rarely seen here have become the mainstream, and the content of sulfide is very rich. These substances, which are highly toxic to ordinary organisms, are food to others, such as ...... Purple bacteria and other chemosynthetic bacteria.

As a primitive class of bacteria, they do not need sunlight for photosynthesis. All they need is water and the right temperature, and all the energy they need comes from the chemical energy released by breaking down the compounds.

The massive amount of material that erupts from the planet's interior can create strange ecosystems in the deep, completely devoid of light ocean floors, because their energy comes from the planets rather than the sun.

As you get closer to this underwater hot spring, illuminated by a beam of light, the place looks like an ice cream mix. Completely different from the dead silence of other parts of the deep sea, there are tons of different creatures huddled together, frantically vying for survival spots, rendering the rocks in a variety of different colors.

Xinglan swam to the rock, and the pressure of the deep sea didn't affect her movements too much. She gently reached out and swept away some of the small shrimp that were scrambling for bacteria on the rocks to eat, and collected some samples of the bacteria.

"It's really unpleasant not to have a right hand......" Xinglan, who felt deeply impaired with her mobility, was very resentful, so she had to use the light-emitting element on her forehead to illuminate the rock, and then use her left hand to collect it.

Hydrothermal vents don't erupt all the time, in fact most hydrothermal vents only erupt for a few months. Organisms here grow quite quickly, but when the eruptions stop, they almost all die completely, so the disappearance of each hot spring often means the extinction of a large number of endemic species.

In addition to small shrimp and small crabs, there are also worms that can withstand high temperatures that move freely in the boiling water that erupts from the ground, and they continue to grow while scraping bacteria from the rocks with their tentacles. These worms are like blooming flowers, one by one in the sea, brilliant in color, very beautiful.

Suddenly, a group of black shadows flew in front of him, and Xinglan turned the beam in surprise to find that it was a large group of small silver fish.

"There are deep-sea fish here, too, and it seems that Lanxing's marine ecosystem is really mature. It's no wonder that the evolutionary potential is assessed as insufficient...... "Xinglan looked in the opposite direction, and the guy who made the fish run away frantically also appeared.

This is a group of squid, and unlike the previous bone-shattering squid, it is called a deep-sea squid.

They are about a meter long, which is not too big, but in the light, it can be seen that deep-sea squid has a powerful ring-shaped hook suction cup on each wrist and foot, which can quickly catch small fish, and in addition, these squid do not have any inflatable tissue in their bodies, so they are not afraid of the huge water pressure of the deep sea.

With a snap, Xinglan tried to turn off the lights, and as expected, these deep-sea squid were all flashing with various colored points of light, and the function of these points of light should be to disturb the prey...... No, it's more than that!

Turning on the infrared sensor to link the actions of the deep-sea squid with the light, Xinglan suddenly discovered that all the light points did not change randomly and randomly. These color changes are similar to those of shallow sea squids, and they are a way of communication between deep sea squids!

The points of light in front of him suddenly turned purple, and the deep-sea squid swarm violently sprayed water to accelerate the pursuit of the fish, coming and going rapidly, and soon disappeared into the deep sea.

"Is it a collective attack signal? Well, leave them alone, the ultrasound scan just now seems to have found something strange. Xinglan reopened the luminous element in her palm and shone on the black smoke that filled the sky overhead, "What's in there...... Come out. ”

After being illuminated by the beam, as if he knew that he had been discovered, a pair of eyes flickering in the light suddenly appeared in the black pillar of smoke, and with the surge of the sea, the long body writhed and swam out of the pillar of smoke......

"There's no strong aggression, isn't such a big guy a predator?" Xing Lan curiously reached out and touched the black creature that slowly swam in front of her, "It's so big, it seems that it should be the type that directly consumes sulfide to decompose the bacteria in the body to provide energy." ”

"If you live by a hot spring under the sea, let's call you Quanlong." After deciding on the name, Xinglan stroked the docile creature, stretched out a probe in her palm, and took a small piece of skin debris as a genetic sample when the other party barely felt it, "Such a large creature shouldn't die when the hot spring stops, it seems that you still have the ability to search for other hot springs." ”

After swimming around Xinglan to make sure that there was no threat, the four-meter-long deep-sea creature swam back into the black chimney, completely concealing itself in the dark smoke.

Then, the girl is on a scientific research expedition......

……

"Okay, the collection of biological samples in this area is complete~" Xinglan stretched out in satisfaction, "Just leave the rest to the underwater robot......"

Standing gently on a nearby rock, Xing Lan looked at the magical place of life in front of him with a smile and waved his hand: "Then, it's time to go back, goodbye...... Huh? ”

Rumble!

With a loud bang, the entire sea seemed to tremble, and countless bubbles erupted from the cracks in the rocks. The rock where Xinglan was standing was directly washed up by the huge water jet spewing from below!

"Hair ...... What's going on? "The incident happened suddenly, Xinglan lost the control of her right hand and couldn't control her balance well, and she fluttered twice in the seawater, but she still couldn't stabilize her body.

"Damn, because the current is too strong to keep a better balance?" Xinglan hurriedly tried to swim into the distance, and just left a distance, only to hear a loud noise behind him, and the entire area where the hot spring was located actually collapsed, and countless creatures fled frantically in all directions!

"Is this an earthquake? The whole region has become like this. Xinglan turned to look at the turbulent undercurrent behind her due to the collapse of the seabed, and couldn't help but be taken aback, "This is not the destruction that can be caused by the power of living beings, is it?" ”

Because of the high sulfide content in the seawater and the presence of hydrothermal vents, it should be an area of active geological activity, and there may even be submarine volcanoes. In this way, it is not surprising that there will be undersea earthquakes.

To be on the safe side, Xinglan was ready to swim some distance to the outside world again, but under the impact of an oncoming huge undercurrent under the seabed, she still had to take refuge on the solid seabed rocks first.

As soon as she landed, Xinglan felt that something was wrong: "How can this ground be ...... Squishy? ”

Before he had time to think about it, the soles of his feet were suddenly sucked by a force, and the ground slammed down, and Xinglan suddenly fell down involuntarily......
