The invisible eye peeks into all things, and it is difficult to find a trace of the vicissitudes of life.

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

Lan Xing, Dragon Soul Age, Outer Ring Ocean.

The ocean, when viewed from above, is an endless blue, but when viewed from below, it is also bottomless. The slow-flowing waves and undercurrents are everywhere, like the wind on the ground, gently blowing everything in the sea.

"Time...... It's really worthless stuff. ”

Long columns of rock twist and stretch upwards from the bottom of the sea, and although they fail to break through the surface, they become reefs. On an irregular surface formed by the impact of the water over countless years, the girl sits in a depression, her long hair fluttering in the water, and stretches lazily for a lazy waist that is not needed by the robot at all.

A jellyfish swam in front of the girl one by one, and if you look closely, you can see that the jellyfish's tentacles carry several small colorful fish. They swim freely in the tentacles of jellyfish's stinging cells, as if they were escorted by bodyguards at any time.

"A wonderful symbiotic relationship, the ocean of the Arashi...... It's beautiful. Narrowing his eyes that were slightly red in the seawater, obviously being in the ocean could not have the slightest effect on Xinglan's current physical activity, "This eternal tranquility, if it weren't just a mechanical body, it would really make you want to sleep......

It's like looking down at the clouds from the sky and finding them as many ravines as the land, and if you replace the air with water, the ocean and the land are not much different...... Except that almost all the creatures that live in it can move in three dimensions.

When spring comes, the surface sea water communicates with the deep sea water to increase the abundance of mineral nutrients deposited in the deep sea.

It's a few kilometers underwater, and it's almost impossible to see the sun above. Xinglan stretched out her palm, and the pale searchlight clearly illuminated the process of a few small white debris slowly falling into her palm.

There is snow on the ocean floor, too, and these small fragments of organic matter may be the remains of a living organism's body, or the excrement of marine life above, but provide a source of food for the creatures below.

And this kind of snowfall, like land, also has a snow season. Organic matter doesn't fall evenly all the time, as most people might think, but it floats for days, stops for a few days, and then then falls downward, which, combined with the almost ubiquitous undercurrents in the sea, creates a wonderful scene of deep sea wind and snow.

"The vitality of life, the spontaneous cycle." Xinglan flipped her palms and let the tiny white debris fall downward, watching them get smaller and smaller as they moved away, and finally disappear into the infinite depth that searchlights couldn't penetrate, "Lanxing, it's so beautiful. ”

It has been about half a month since she dived into the ocean again, and this time is not enough for Mi Xin to deal with the major matter of racial reproduction, and Xinglan still has enough time to explore this ocean carefully instead of directly browsing the information sent back by the automatic robot.

The ocean of the Dragon Soul Era has undergone 200 million years of evolution, and although the shadow of the Marine Age can still be faintly seen, most of the creatures have taken on a new look...... The small cells that were thrown into the primordial ocean together with Xinglan and Xiao Cheng back then were even more different.

Xinglan didn't know how Xiao Cheng, who was still in the dormant pod now, and might even lie down for many billions of years, would feel when he saw these scenes, but it was far from Lanxing's emergence of advanced civilization...... Even the mere appearance of human-like creatures on Earth will have to wait.

No, at least there is a creature that is very similar in appearance, and they are the kind of creatures that Xinglan is still focusing on: the sea giant.

The autobots responsible for taking care of the Sea Giants so that they do not become extinct in the Starfire Age Cataclysm relaxed their monitoring efforts after the Lan Xing Ecology entered the normal situation again, so that at some point, the Master Brain of the Dead lost this species of creatures that may be the most intelligent on the Lan Star at present, but Xing Lan did not deliberately send a large number of robots to conduct a carpet search, but personally started the gradual search from the place where the Sea Giant finally disappeared.

She is not in a hurry, because she has time, as long as the sea giant is still on Lanxing, she will find it sooner or later.

Xinglan groped her fingers on the rough rocks, and with the help of a stream of water that happened to be rushing from behind, she jerked away from the rock pillar, flapping her legs and swimming forward, which was already close to the bottom of the sea in this area, and she could even faintly see the seabed stretching below.

"Thruster Start......

Rumble!

Jet propulsion backpacks aren't just for flying in the air, they can be used for fast underwater travel with a few modifications...... Of course, the premise is that the user can withstand the huge impact of the oncoming water.

……

The small, slender body of the knot fish shook under the impact of the current, and it skillfully drilled through a hole in the rock, tied itself in a knot to hold its body in place, and stretched out the tip of its forked tongue to feel the movement of the water, which made it look like a snake...... Or maybe it's really the ancestor of snakes, who knows?

The 200 million years of evolution, including the Spark Period, do not seem to have been able to produce much variation in their appearance, except for the addition of many varieties of different bands of knotfish. The large, silver-gray eyes, just like they did 200 million years ago, observed the underwater world with keen eyesight, watching the white splash left by the figure that flew away from the rock pillar.

The strange thing is that the knotted fish, which originally had no complicated thinking, suddenly fell into a state of contemplation, and countless images and information were seen from its eyes, but not only thought by it, but countless fragments of data that did not belong to it were also running rapidly in its mind.

"Regression...... How to treat ...... Land...... Sky...... It's a long time...... Individual...... Colony...... Unidentified ......"

Without a linguistic foundation, these are just instinctive fluctuations of thought.

Tear and pull!

A bright flash of light interrupted the knot's thoughts, and a small but deadly electric current slammed through the knot's strip-like body, bursting into a cloud of light on it, taking its life in a split second, and some invisible creature quickly pounced after the current, tearing at the knot's body......

It didn't notice that a small purple spot had appeared on the belly of the dead knot, but the purple spot had been charred and was quietly dissolving in the water after the electricity had passed through it.

When it is strong, it is strong, but there is always a limit.

……

【Diary of Diving in the Outer Ocean of Lanxing】

[In the first month of diving, I started my journey from the Sea of Algae, and after leaving the outer sea area covered by airbag jellyfish, I continued to dive. Visibility in the sea is very low, and even with ultrasonic positioning, it is difficult to clearly spot distant objects, which makes the search very difficult. 】

[In the second month of diving, I don't know why, it always seems that I feel like I'm being watched by something...... Is it a delusion? If you scan the signal in all directions, it won't be fun...... A few scattered fragments of stone rods were found underneath the soil, but they were all long, long years ago. 】

[In the third month of diving, it seems that the area where the sea giant once lived has been determined to be uninhabited, and even the sea tree forest has not been found again. Considering the possible adaptive evolution of the sea giant's exoskeleton to seawater pressure...... Maybe we should go deeper into the ocean? In contrast, however, they are a little more likely to migrate sideways. 】

[In the fourth month of diving, when I left the original sea area to expand the scope of searching, I found a few sea tree wreckage, although it was only a lonely wreckage, but it seemed to point out the direction of the sea giant's migration route, which should be a good clue. It will take a while for Mi Xin to be there, and time should be in time. 】

【Fifth Month of Diving...... Bang! 】

So five months later, Xinglan, who was standing on a reef like a chariot charge, was smashed by a breeding pod that fell from the sky before she could finish writing this log......

…… Yes, that's right, a breeding egg compartment.

"Who's idle and littering!" The voice full of resentment seemed to solidify some kind of black aura in the seawater, and Xinglan, who fell on the reef in a frustrated forward posture, silently watched as some kind of ring-shaped hose-shaped unknown object that had just hit her fell forward, bursting open, leaking large white spherical particles scattered and splashed in all directions......

Xing Lan, who almost instinctively flashed backwards, looked up, and was instantly shocked: "Do you still have two layers of aura for a fish?" ”

A large fish with a body length of seven or eight meters slowly swam from above, this size is not surprising in this era, but if there are two halos around the belly of this fish that do not meet the needs of a streamlined body at all...... In fact, it is a flesh and blood body covered with fluorescent cells, which is really surprising.

At the moment when Xinglan looked up, the fish ...... Let's call it the ringfish, and the ring-shaped object around it twitched violently, and once again broke away from a ring-shaped tubular object and fell downward......

The corners of Xinglan's eyes twitched as she watched as countless small white particles burst out in front of her again, each of which was a fish egg...... This kind of fireworks-like diffusion is simply impossible to complain about.

The reef trembled slightly, as if it had actively changed direction away from the fish roe area, and the vibration from the sea also told Xinglan that there seemed to be a large number of moving targets approaching in the distance.

"It doesn't matter what the world is...... Such irresponsible parents......" Xinglan watched the fish twist and leave without looking back, "Most of these mass-produced fish eggs are destined to become a meal for other creatures. ”

After the reef changed direction, it trembled slightly and regained its stability, and the sea water drained out of the hole at regular intervals, pushing the reef, which was very close to the density of the water, forward in the water.

"Maybe you should look for the submarine mountain or something, maybe it's easier to find the sea giant......" Xinglan thought slightly, in the first two months, the jetpack ran out of fuel, and after instructing the automatic robot to bring it back to be destroyed, Xinglan chose to take a reef ride to continue the search, "Anyway, there is time to ......"
