The cycle of ocean currents is in crisis, and the bubbling time meets by chance.

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

At night, plankton come to the surface to move.

When night covers the world, countless small creatures will emerge from the underwater caves where they hide during the day, and float all the way to the surface of the sea to enjoy a wonderful feast.

In addition to single-celled organisms, some small fish also come to the surface at night to look up at the stars, and their large eyes are a sign that they have adapted to the dark environment of the ocean floor.

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

The calm sea suddenly began to tremble, and a series of bubbles rose from the depths. The little creatures were frightened and roamed around, could there be some big ones coming?

Grunt...... Grunt...... Crash!

The little fish watched in horror as a behemoth emerged from the ocean, and silver strips larger than their bodies scattered in all directions...... Is it a tentacle used for predation? Come on!

……

"Ahh......h We seem to be getting weird! How can you imagine your hair as a tentacle? Xinglan slapped the sea with her feet, exposed her head to the sea, reached out to pull away the silver hair wrapped in front of her, and hurriedly turned off the strange brain supplement screen, "Although it is said that the robot's body does not need to be ventilated, but if it is stuffy for a while, it will really become a deep-sea creature!" ”

As if to heighten the atmosphere, Xinglan mischievously released some bubbles from the gas storage chamber in her body even though she didn't need to breathe, simulating the appearance of breathing.

However, after soaking under the sea water for three hours, Xinglan still couldn't help but surface, leaving her robot brother with her to continue collecting biological samples, and she is very unhappy now, yes, quite unhappy!

"Hmph, I'm looking for interesting large creatures!" Xinglan pursed her lips aggrievedly, "After swimming so far, I can't even see the coast, although the number of creatures is a lot, yes, but there are creatures everywhere along the way that are so small that they are tired to look at, what kind of trouble?" The largest one is more than a dozen centimeters long, and the highest species is a mollusk...... Not to mention bones, I haven't even seen a creature with a hard shell until now, what kind of trouble? ”

What's the place...... Wrong.

Unconsciously flapping her feet and floating on the water, Xing Lan frowned tightly and thought: "Judging from the sea area I have been to before, sea giants, cave worms, porous tube worms, and boomerang ...... These are all very advanced creatures, and the calculation data given by the Death Base can also show that the evolutionary potential is almost exhausted, and it stands to reason that Lanxing should have evolved a very complete marine ecosystem, but ...... How can even the highest creatures, that is, primitive mollusks, be here? ”

This mollusk, which has no hard tissue, will not even have fossils preserved, and Xinglan has asked the underwater robots to start collecting the genetic information of the creatures here and freezing some live specimens...... Preserving these primitive creatures is much easier than preserving humans.

But the question remains unsolved, why is there so much difference in the level of evolution between the two seas?

"Wait!" Xinglan suddenly looked up at the sky, "The sea giant's human genes were unlocked in advance because the gene lock was destroyed by high-energy radiation, and before it fell asleep...... The gamma rays that leaked into the Orchid Star happened to bombard that area of the sea and caused biological mutations? ”

If you look at it by location...... Xinglan flipped through the memory bank, yes, it was that sea!

“…… Still something is wrong. The girl simply plunged into the sea, rising and falling with the waves, looking at the infinite dark blue in front of her and meditating, "Five hundred million years have passed, even if the evolution of organisms over there has accelerated, but according to the diffusion speed of organisms, there should not be such a big difference!" Unless...... Stuck? ”

The signal cells that were freely diffusing in space suddenly moved, turning into tens of thousands of signal sub-streams and rushing into different seas of Lanxing, staying for a minute before returning to space at the speed of light again.

"Hmph, that's true!" Xinglan closed her eyes, and the huge computing power of the signal subnetwork quickly analyzed the information on the concentration of substances and the flow direction of the sea water she had just collected, "Ocean Current Circulation...... That's a problem. ”

The Pan-Ancient Land of Lanxing is...... Well, the shape of a dog's bone, which has an impact on the route of the sea that takes advantage of the differences generated by solar energy to move. The circulation of seawater in the depression below the continent forms a huge circle around the sea, like an invisible giant vortex, sucking a large amount of mineral elements from the outside world into it and depositing it. This invisible ring of ocean currents does not stop marine life from migrating out, but it creates a circle of extremely nutrient-starved marine areas nearby. Without nutrients, plants can't grow in large numbers, and animals can't replenish enough food along the way, so almost all of the species that survive in this nutrient-starved zone are smaller and very few species. Although there are still abundant material resources outside the nutrient-scarce zone, and small animals are quite prosperous, the average large organism is not capable of crossing the wide nutrient-scarce zone, and in contrast, they prefer to survive in the resource-rich circular sea area inside the annular current.

"This system of ocean currents...... That's a big problem. Xinglan pressed her forehead sadly, expressing her helplessness at this unexpected situation, "It's not a global cycle, this predatory current will cause the collapse of the entire ecosystem sooner or later!" Besides, most large creatures are crammed into one ocean area, which is not what I want. ”

Xinglan soaked in the water and bit her fingers: "Well, forget it, it's going to be ...... soon anyway Let's take this opportunity to break the original sick material circulation system in one fell swoop. If you want to change the shape of ocean currents, you can modify the sea and land framework. So, what else needs to be done on Judgment Day is...... Divide the continent? ”

……

Crash!

Xinglan emerged from the surface of the sea again, taking a deep breath of the cool air of the sea...... Although she couldn't breathe in anything.

"If you want to observe interesting marine ecology or something, should you really go back to the original thriving sea?" Xinglan turned her head to look at the white horizon in the distance, feeling powerless, "Do you have to swim back?" Just kidding......"

Xinglan suddenly regretted that she didn't add a flying device to this robot's body, otherwise with the durability of nuclear power, it would be feasible to fly back to the original sea area directly.

Slander is slander, no matter how much Xinglan likes to spoof and doesn't really plan to swim all the way back, but is ready to send a signal for the carrier plane in space orbit to come down and send it off.

Well, that seems like the perfect plan.

However, when Xinglan was looking up at the sky and was about to send a signal......

Crash!

It was also the sound of water, but the intensity was far from being comparable to Xing Lan's bubbling just now, the huge waves that were dozens of meters high were scattered and splashed, and Xing Lan didn't react to what was happening, but only felt a huge stream of water rushing over, and his body was involuntarily thrown backwards and hit the obstacle fiercely......

Bang!

"Woo...... I'm so dizzy......" Xinglan, who was hit the head, covered her head stiffly, and with the seawater flowing from the corners of her eyes, she was suspicious of tearful malicious cuteness, "......What the hell is such a big wave?"

"Resting ......"

A familiar long roar suddenly made Xing Lan raise her head in surprise, only to see countless huge white muscles trembling on the dark blue skin that occupied almost the entire field of vision, and spilling strings of water droplets......

It's a whale! Xinglan's eyes widened, and she suddenly felt a moment of fear that the almost 100-meter-long behemoth in front of her was headed upwards, and a big mouth large enough to swallow a car was slowly closing...... So, we almost got eaten in one bite just now?

Xinglan, who knew the recipe of the whale, had no doubt that the whale would take the initiative to attack him just now, and even if it was really eaten, it was probably an unintentional injury by this big man......

Not to mention that Xinglan is only 1.4 meters tall now, just looking for a muscular brother who is more than two meters tall is expensive, and he is a little bit in front of the whale!

But just now I was complaining that these are all small animals, and suddenly such a big guy is too ...... Eh, wait!

Whales feed mainly on small creatures, which are abundant in the absence of large predators, and are more than capable of crossing the wide nutrient-starved belt......

It makes sense that there will be whales here!

"However, the presence of whales is not necessarily a bad thing." Xinglan looked at the behemoth in front of her, "When they come here, they must have a fixed migration route, so they will inevitably return to the original sea area......

"Hmph, there's a way to go back!" Xinglan checked the adsorption device on the wetsuit, which was originally used to help divers attach to the reef in the event of a tsunami or other disaster, but at this moment, it may be used to ride whales?

Like a thief, Xinglan tiptoed towards the whale that had stopped in place with her mouth shut in front of her. Feeling the fluctuation of the current, the whale's eyes were almost as big as a human to open, and he glanced lazily at Xinglan, not caring about the insignificant little guy in his eyes, and continued to squint and rest.

Well, it's a good opportunity~ Xinglan was just about to step forward in excitement, and was suddenly stunned.

…… Wait, seem to have forgotten something very important?

Xinglan recalled, her body stiffened suddenly, just now, when she seemed to be rushed backwards by the huge wave, her head hurt, right?

The head hurts because it hit something, right?

It's so far from the shore, and the water is so deep, it doesn't seem like there's a reef, right?

So, what was the head-bump just now...... What is it?

Xinglan slowly turned her head with a dull expression, just in time to meet a pair of eyes.

"Rest ......" is the same sound, but the volume is significantly lower.

"Good...... It's so cute......" Xing Lan stared blankly at the little whale in front of him, which was only about one meter long, but was almost a miniature version of the giant beast, and the other party's small eyes looked at Xing Lan in front of him curiously, revealing a trace of grievance.

Well, seeing a small piece of redness and swelling on the forehead of the little whale, Xing Lan instantly understood what was going on, obviously this little guy couldn't hit Xing Lan who had an iron head......

Inexplicably a little distressed, Xing Lan reached out and gently stroked the wound of the little whale in front of her, probably because of her young age, the other party had no fear, and her eyes were full of curiosity. Seeing this scene, Xinglan was even more sorry, and held the little whale in her arms and comforted her.

Hey, girl, have you awakened some strange maternal consciousness?

……

Soon after, the mother whale was almost resting, and she suddenly opened her mouth and let out a long call.

The little whale in front of Xinglan suddenly came to his senses, and happily swam towards the mother whale, halfway through the swim, as if he remembered something, swam back and rubbed Xinglan, and nodded his head in the direction of the mother whale.

Huh? Xinglan also tilted her head, is this an invitation?

Seeing that Xinglan was willing to follow him, the little whale became even more excited, and it took Xinglan to a place on the mother whale covered with white whiskers, and called several times in a row, as if to express something.

After a while, I heard a response from the mother whale, and somehow, Xinglan seemed to hear a trace of pampering and helplessness from the call of the mother whale.

The white whiskers on the mother whale's back moved violently, not tightly wrapped, but gently wrapped around the little whale and hugged it gently...... Xinglan reluctantly found that she seemed to be being treated in the same way.

Hey, what's going on? Does the mother whale regard herself as a guest or a toy for the calf? After a little belly scolding, Xinglan still obediently nested in the quilt woven by white whiskers...... Gently turning off the device on the wetsuit, it seems that the adsorption device is no longer needed.

With a huge surge of currents, the mother whale left the area and began to follow her already defined route......

Among the white whiskers on the back of the mother whale, Xinglan and the small whale on the opposite side looked at each other eye to eye, and the small whale called happily a few times.

"The little guy can't do it if his vigilance is so bad all the time~" Shaking his head helplessly, a smile appeared on the corner of Xinglan's mouth, why did he suddenly feel in a good mood?

In addition to forcibly controlling the biological nervous system, it seems that making friends is also a very interesting thing~

Wait, it seems that you have forgotten something? …… Hawkers, forget it, don't worry about it.

……

The automatic underwater robot watched the figure of the whale gradually disappear, completed the task of collecting genetic samples, and did not receive new instructions, it could only float in the sea and look at the sky blankly...... Abandoned?
