The cave was illuminated with golden light, and the fungus of light entrenched itself on the stone.

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

Last time, I said that the Sea Giant Squad went through nine hundred and eighty-one difficulties, and won the Sutra Book Sanzang (several silver silk sacs to be opened) from the active attack poison monster Flame Fish in the Sea Tree Forest, and then because I forgot to bring it back to the city scroll, I had to kill all the way back after suffering countless scene injuries (passing by the soy sauce people), and finally arrived at my hometown, and happily opened the treasure chest (silk sac) with other members of the union (family), and got a number of rare meat that can add attribute points.

But the good times didn't last long, after opening the treasure chest...... Ahem, after the silk sac, in view of the limited amount of rare meat that can be used every day, the Sea Giant Guild did not recharge to buy promotion props after using today's share, so they had to sort out and store these items together, but because this place did not belong to the safe zone, a cave worm from the Guild next door was red-eyed, relying on his relatively high level, trying to blackmail the Sea Giant to obtain rare meat. The Sea Giant Guild united and fought hard, and after paying the price of a member's deletion, they relied on the strength of the group to kill the cave worms, and exploded a number of props such as cave worm meat and cave worm shell fragments. After the battle was completed and the regular consumables were packed, several female sea giants with the special life skill "Silk Capsule Processing" finally picked up the "Silver Silk Capsule Fragments" that had been dropped earlier, and prepared to enter the special cave scene for unknown special material production activities.

……

Odd...... Xing Lan'a, who was still in a state of consciousness, shook her little head that didn't exist, and always felt that there was something wrong with the passage she had summarized......

"Well, when are we going to start struggling with the details like those ordinary creatures?" Xiao Xinglan, who unconsciously lost her temperament, continued to staggered behind several female sea giants, muttering, "I'm astral conscious...... Although it is self-appointed~"

After subtly complaining about herself, it seemed that she had successfully vented some of her psychological pressure, and Xinglan refocused her attention on the scene in front of her.

Well, although it's a serious matter, it's actually just floating......

This cave is actually very deep from the outside, and the long tunnel leads downward, and at a glance, the place that cannot be illuminated by the stone rods is completely submerged in unknown darkness.

Of course, for Xinglan, whether it is dark or not doesn't really matter much, if she wants, she can even completely scan the entire interior of the undersea mountain in an instant. But what's the point of playing a game that knows everything?

……

There were no sapient beings in this era, and the sea giants obviously did not dig tunnels, so this tunnel was formed by nature...... Perhaps it's more appropriate to call it a rock gap, full of rocks and crevices.

Since this is the bottom of the sea, there are no stalactites and other wonders except for some rocks that are very smooth by the sea, which can't help but disappoint Xinglan, who is full of expectations.

However, unlike a certain Ah Piao who is purely for sightseeing, for the sea giants, their life is not very easy.

Reaching an average height of five meters, sea giants will always bump into sharp rocks as they walk through narrow crevices, and even though most of their bodies are protected by hard armor, their soft skin is still scratched with blood.

The rocks that were washed smooth by the current were even more dangerous, because the passage was all the way down, and once they stumbled, the sea giants' poor swimming ability was enough, not to mention that because the cave was so dark that the female sea giants came down with illuminated stone rods.

Fortunately, because this is the ocean, there is no suffocation of caves due to lack of oxygen that often occurs on land. In addition, the Sea Giant's glowing stone rod is not a torch that consumes a lot of oxygen, although bacteria also consume some oxygen, but this small loss is almost negligible.

……

Drill the cracks, drill the cracks~

Turning around a quagmire pool of slime...... The density of these strange slimes was so dense that they were able to form a fixed pond at the bottom of the sea, and watching the sea giants seem to be trudging through a swamp, Xinglan was inexplicably glad that she didn't have to walk on the ground......

Ahem, digress. In short, when I turn an intersection by chance, the passage ahead is suddenly no longer so dark, but a little shiny.

Huh?

Suspiciously, Xinglan examined the visual perception system composed of signal pros, and then looked ahead...... That's right, there is indeed a glimmer of light at the intersection ahead.

It was strange to know that they were now in the interior of an undersea mountain range, and by calculating the inclination of the previous road, it was impossible to cross the entire mountain range now.

So, how can there be light here?

The sea giants did not hesitate, and the female sea giants walked into the suddenly open passage with ease.

Underground caverns.

Xinglan's first reaction at this time was this.

Just like the ground, there are huge cavities in the water-filled underground, and these so-called blue holes retain only a faint connection to the outside world, allowing them to evolve unique ecosystems that attract intelligent beings to explore. But like the caves on land, the Blue Hole is a labyrinth of rocky tunnels that are scattered irregularly and full of strange rocks. Because of the underwater relationship, it is far more dangerous for intelligent creatures on land to explore the blue hole in the water than to explore the cave on the ground.

……

Unlike the dark and closed underwater cave in Xinglan's imagination, the huge underwater cave in front of him is not only very open, but also quite ...... Bright?

The lights are brilliant.

This is not the work of the glowing plants, but the entire rock walls of the cave are shining, and when you look up, it looks like the starry sky outside is shining.

"It's a glowing bacteria!" Xinglan was shocked to turn on the simulation perspective to panorama mode, and could see anything in any direction, carefully examining this unknown world.

Not only the rock walls, but also countless tiny points of light float in the sea that fills the cave, and it seems that all the bacteria are scrambling to show their brilliance.

This is the light emitted by the mitochondria that burns life at the cost of burning lives.

Looking down, Xinglan noticed that countless pillars of rock resembling stalactites had been erected on the ground, and a large number of luminescent bacteria had gathered on these mineral-rich rocks. Bacteria wrap around the surface of the rock, gradually erode inward, and use light to break down some special components inside the rock to obtain the nutrients they need.

But how does it look familiar?

Looking at the sea giant again, Xinglan suddenly realized, isn't this the kind of stone stick in the sea giant's hand?

…… Feelings, you don't even rely on your own wisdom to polish the stone stick, but break it directly...... Invisibly, Xinglan's evaluation of the Sea Giant's wisdom level fell again......

It seems that they are not very adaptable to the outside environment, and the light emitted by the stone rods held by the sea giants has been slightly dimmed, which means that the luminescent bacteria on it have begun to age and die in large quantities, so they must be replaced~

The powder of the rock discharged from the bacterial erosion formed a layer of soft sand at the bottom of the water, and the female sea giants stepped forward, gently inserted the stone rods in their hands into the sand, and then took out the fragments of the silver silk sac, carefully wrapped the stone rods, and straightened them.

As if sensing something, the glowing bacteria floating in the surrounding sea began to move closer to these returning stone rods.

Waves of undercurrents gushed out from the cracks in the rocks, bringing oxygen and nutrients from the outside world continuously, but the photobacteria at this time ...... Let's call it that, after all, you can't call it a narrator, right...... In short, the photobacteria at this time are not short of this nourishment.

Silver silk sacs, which are made up of special proteins secreted by sea trees to hunt small sea creatures. The proteins are so strong that even sea giants need to cut a small part of it with a sharp fingernail. If an ordinary animal eats this macromolecular protein that is more difficult to decompose than cellulose, it is definitely not digested properly. Good, but for these photobacteria that can be eroded and digested even by rocks, it is obviously a piece of cake, not only can they be decomposed, but this is also a high-protein supplement!

……

"Well, so those silk sac fragments are breeding fertilizer?" Xinglan muttered to herself, but of course no voice would answer her, "Should we say it's high protein, chicken flavor, crunchy......"

Although it is a pity that I can't say "remove the head and eat ............

In other words, shouldn't breeding bacteria be something that insects like ants like to do? You five-meter-tall guys are going to carefully breed bacteria, okay? Xinglan complained as always.

Lanxing's earliest breeding industry and lighting industry can be applied for world records...... Hmm, maybe it's a cosmic record?

"The Most Ancient King (Fungus)~You really like gold shining~" Xinglan grinned, "Although I always feel that there is an unknown dimension of the tsundere character who is inexplicably lying down......"

Hawkers, why bother with the details? It's all the world's fault~

In any case, it is gratifying that the mystery of the sea giant's use of the silk sac has finally been solved. Although Xinglan was a little disappointed that there was no production process such as weaving, it should be expected when you think of the brains of the sea giants who have not yet fully evolved.

As for why sea giants without advanced wisdom know how to take the initiative to breed photobacteria, this is probably an instinctive symbiotic relationship of animals, just like leafcutter ants breed fungi......

……

Watching as the female sea giants pulled out several incomparably bright stone rods next to them, each sea giant took multiple stone rods and began to walk back. Xinglan immediately knew that there were no other secrets here.

Well, it's just a simple farm.

I didn't have the patience to wait for a few female sea giants inside to slowly crawl back...... Well, climbing up is slower than going down, and Xinglan directly began to accelerate, rushing straight up with the ability of the signal to ignore the blocking of ordinary matter!

After a few hours of travel, after Xinglan sped up slightly, in just one minute, she "whizzed" out of the rocks on the gentle slope of the mountaintop, floating in the water......

"Squeak Squeak......"

"Roar, Roar, Roar, ......Roar, Roar, Roar, Roar, T

……

"Huh?" Xinglan was a little dumbfounded as several sea giants on the gentle slope below were waving stone sticks and roaring loudly, while on the other side, it seemed that an endless sea of insects was slowly surging up from under the cliff......

"What...... What is the situation? ”
