The hull of the ship shook more and more violently, and on the second floor deck, Zhou Ai and Roy clung to the guardrail to stabilize their bodies, and their facial expressions could not be seen under the mask cover, but they didn't look very good.

This is no better than the ocean of habitable planets, and if you fall into the water and fish it up, you are afraid that even the bones will be gone.

Tang Fang looked at the approaching storm surge, sighed, and muttered to himself, "Is it really going to be in vain?" ”

The storm surge is nothing in its eyes, no matter how strong the corrosion ability of acid rain is, no matter how powerful the lightning strike is, no matter how high the wave is, as long as you dodge in the Protoss transport plane, it can naturally be safe, the key is that the storm surge does not know when it will recede, according to Emma's analysis of the satellite cloud image, the nearby abyss is also within the scope of the storm, and it is difficult to subside in 3 or 5 hours.

If you drive the landing craft to the other hemisphere, not to mention the delay, there will be no result if you don't do it well.

"Commander...... The results of the analysis of the injuries of the puppy and cockroaches and the sour water are out, which is very strange. ”

Emma rarely uses the word "very strange", which suggests that the results of the system's analysis of the sour water must be very different from the official report of the Covenant.

He beckoned Zhou Ai and Roy to come down and start the boat, leave this sea area, and then sit back in the cockpit and sink his consciousness into the system space: "What do you mean, be specific." ”

Emma transmitted the pH value, the proportion of seawater composition, and the combined water pressure of different sea depths to the digital display system of the harsh environment protection = protective suit, and then explained the specific meaning of "very strange": "The composition of the acidic matter in the seawater is very similar to the organic acid gas in the strong acid vapor area of Namei Star, except that the former dissolves in water, while the latter adheres to the ground. ”

Where does the strong acid vapor of Na'i Star come from, Tang Fang knows it well, it is not a chemical reaction from the depths of the earth's crust officially introduced by Mengya at all, but from the epic creature evil eye, to put it bluntly. They are the excrement of the evil eye.

The acidity in the green ocean of "Akron" is similar to that of Na'vi, does that mean that this planet also has evil eyes?

According to Valentine's research results, AQBD-1 clonoid jellyfish feed on free zero elements in the ocean, and have no relationship with acidic substances. This suggests that there must be something that continues to inject a mixture of zero elements and acids into the seawater.

Trace amounts of zero element is the food of AQBD-1 clonal jellyfish, acidic substances are the root of the formation of strong acid oceans, the evil eye feeds on zero element, and there will inevitably be trace amounts of zero element residue in the excrement in addition to organic acids, and "Akron" is a planet with rich zero element reserves.

Based on the above situation, there is a high probability that there is an "evil eye" hidden in the depths of the "Akron" abyss, or in the strata.

Tang decided to go to the bottom of the sea, but the biggest problem he encountered was how to resist the corrosive effect of seawater and the strong water pressure. Even if the Immortal and Protoss transport planes could dive tens of thousands of meters to the bottom of the sea, how could he get underground? Is it possible to find a shallow place to dig a tunnel with cockroaches? That would turn into a protracted project.

What he lacks most now is time, and he can't afford to spend it here.

"If the acidic substances in the seawater are the same as the acidic substances in Nami Star, they are organic acids, then wouldn't it be ......"

A pair of high-powered turbines stretched out on both sides of the landing ship's third deck, emitting a low hum, and the water directly below was like sheets blowing in the wind, splashing in all directions.

The landing ship slowly lifted into the air under the lift of the air current. At a height of several meters, the tail engine is full of flames. Pull out 2 quickly dissipating smoke rails in the rear, and go away in a blink of an eye.

The clouds were still gloomy and thundering, and the sea area where the landing ship had been located was quickly engulfed by the storm surge a few minutes later.

…………

Half an hour later, the landing craft came to the skies over an abyss with a depth of 32,000 meters in the northern hemisphere of "Akron" and slowly landed on the surface of the sea.

This is different from the location where the previous stay was made. It is a calm sea area selected by Emma after analyzing satellite cloud imagery, and the sea area will remain calm and sunny for the next 48 hours.

The 32,000-metre-deep abyss is not the deepest abyss in Akron, but it is one of the areas with the most volatile concentrations of acids, according to the Covenant's official monitoring figures over the years. It is highly likely that the bottom of the sea is dotted with the excretory pipes of the "evil eye".

After the landing ship stopped, Tang Fang did not release the immortal to explore the bottom as soon as possible, but walked to the rear deck of the first floor equipped with a crane, released a worm, and issued a somewhat uncivilized order to the big guy with a blank look and sighing.

The queen walked to the edge of the deck with her slender six legs, protruded her buttocks out of the deck, and with a pop, drained a lump of fungus blanket tumor into the sea.

Roy, who was watching the wind on the 2nd deck, hurriedly blindfolded, Zhou Ai asked him curiously why he did this, he said that the monster was called "Queen of Worms", the girl pulled the corners of her mouth, only to be silent, thinking that no wonder this kid was always bullied by Bai Hao, this pedantic energy is the same as Valentine.

Tang Fang didn't notice the conversation between the two on the second deck, he grabbed the stern railing and leaned over to look at the sea.

The weight of the fungus blanket tumor exceeds the buoyancy of the sea surface and sinks immediately after falling into the water, and it is difficult to observe the underwater changes due to the light green color of the acidic water.

After waiting patiently for more than ten seconds, there was movement under the water, the flat sea surface was gradually surging, the original green water surface was flooded with a red tide, which quickly spread to the distance, the sea water retreated to both sides like a low tide, and the sea area behind the landing ship suddenly surfaced a floating island with a diameter of nearly 100 meters, trembling slightly with the ups and downs of the sea water.

Zhou Ai and Roy stayed where they were, staring straight at the reddish-brown island, not knowing what to say, or admire, or complain about.

They hadn't experienced the Battle of Na'vi, so they didn't know that the fungus blanket tumor could "ferment" organic tissue into a colony environment where the insect colony depended, and the idea was simple, a lump of "poop" could evolve into a floating island? Or in such a sea of strong acids as "Akron", how is this possible!

Tang Fang didn't have time to explain to the two of them, but the scene on the sea gave him great encouragement.

A bacterial blanket tumor can expand into a floating island of nearly 100 meters, but what about 100 bacterial blanket tumors? There are more than 80 worms in the system space, so why not build a fungus blanket tunnel to the depths of the abyss?

Thinking of this, he no longer hesitated, and passed the command to build a mushroom blanket tunnel to each worm.

Wormholes are formed on floating islands. The first batch of insects then walked to the edge of the fungus blanket and continuously discharged the fungus blanket tumors into the seawater.

In just a few minutes, the area of the mushroom blanket floating island became larger and larger, expanding from the original 100-meter level to the kilometer-level level.

The second, third, and fourth batches of insects appeared one after another, and some of them jumped directly into the water and endured the corrosion of the acid water. Drain the bacterial blanket tumor underneath the floating island.

There are also some insect queens who use the "burying" skill to sneak into the bottom layer of the fungus blanket floating island, and directly attach the fungus blanket tumor to the edge of the fungus blanket, so that these reddish-brown substances expand and expand.

Zhou Ai felt that the world could no longer stop Captain Tang, in just a few minutes, he actually built a floating island that grew larger and larger with the passage of time in a marine environment like "Akron", if the Star Alliance official knew that he had such an ability, God knows what those forces that coveted the zero element resources of the "Akron" formation would do.

Roy's idea is very simple, Brother Tang is too handsome, and no kind of predicament can stop him. What is it for some rich people in human society to spend a lot of money to buy a small island, look at others, and build it themselves!

Tang Fang collected the exhausted energy of the insects into the system space in batches, and released them after they recovered, and so on, and the floating island extended to the bottom of the sea in 100-meter increments.

…………

After an hour, the floating island had expanded to several kilometers in diameter, and its base was even wider. It is tens of kilometers long, and it fits with the increasingly narrow abyss. It almost fills the inner space of the sea abyss.

The landing ship had moved from the sea to the fungus blanket island, and Zhou Ai and Roy jumped off the deck, stepping on the resilient fungus blanket and looking at him blankly.

Tang Fang walked towards the center of the mushroom blanket floating island, and said in a deep voice: "'Akron' is really not a good land. ”

Zhou Ai was puzzled: "How do you say it?" ”

"AQBD-1 asexual jellyfish are not native to the planet...... There's something even weirder hidden underneath. ”

"You mean there's a situation in the depths of the abyss?"

Tang Fang nodded, summoned a certain number of puppies and cockroaches from the system space, and gave them the command to "open the way".

The cockroach activates the "Buried" skill. Find the fungus blanket tumor in the middle of the floating island and destroy them one by one, and the puppy quickly cleans up the shriveled and shrunken fungus blanket material, creating a large cavity with a diameter of more than 100 meters.

He produced another Nighthawk, and three people were in the cockpit. Slowly descend through the bottomless hollow.

At a height of 32,000 meters, it took nearly an hour to clean up alone, and by the time the nighthawk descended to the bottom of the large cavern, the floating islands formed by the fungus blanket had filled the lower layer of the abyss, and both the sea water and acidic substances had become nutrients for the colony to be sucked dry and devoured, leaving only mottled rock formations.

Three sets of ultra-high-power searchlights are installed under the nighthawk's fuselage, illuminating the entire ground as bright as day, and even the remaining fungus blanket material between the rock crevices can be clearly distinguished.

Tang Fang subconsciously looked at the sky overhead, and his eyes were dark, only a very small wellhead-shaped ring light source emitted a misty white light, and it was already faint and difficult to distinguish when it reached the depths of the sea abyss.

He grabbed the cable hanging from the Nighthawk's bilge and slid down, leading the two to the lowest point of the abyss, and using his hands to pull out the dried fungus blanket material, revealing a dark hole underneath, and wisps of green steam spewing out, presumably the source of the acidic substance in the seawater.

Roy subconsciously dodged some, the corrosive power of the seawater alone was staggering, not to mention such a strong acid vapor.

Zhou Ai's breathing was a little short, and she could see that she was very excited, because the three of them were the first human beings to arrive in the depths of the "Akron" abyss, and also because of the "thing" in Tang Fang's mouth, although he did not explain it in detail, but the smart girl had already thought of a deeper meaning, and she was afraid that the culprit who created this strong acid ocean was the "thing" in Captain Tang's mouth, and such a thing was not a good thing.

She looked at Tang Fang's face, didn't speak, just looked at it.

Tang Fang naturally understood what she was thinking, and said, "Yes, I want to find it!" ”

Zhou Ai didn't say anything more, and pulled Roy to the side.

The combination of cockroaches and SCV appeared in the field, and began to dig down the hole that spewed strong acid steam, and according to Tang Fang's order, the hole was widened into a tunnel that could accommodate two people in parallel.

Because of long-term immersion in the water. The cave is filled with an organic acid solution with extremely strong corrosive ability, and Tang Fang can only use the bacterial blanket tumor discharged by the insect queen to convert the organic acid solution into a bacterial blanket again, and then let the insect colony clean them up, although it is a little slower, but it is still a safe way to advance, because in this way, the problem of the acid solution can be solved. It can also filter out the strong acid vapors that escape.

Under the lighting of the harsh environment protective suit, a group of 3 people slowly advanced deep into the ground, I don't know how long it took, and I don't know how deep they dived, the swarm in front of them was responsible for opening the way, and the cockroaches attacked something without knowing it, and then the whole tunnel began to shake violently.

The shaking continued for more than ten seconds to subside, and Tang Fang took a deep breath and let go of the hand holding the wall.

According to the fragmented footage sent back by the cockroach that opened the road at the front, he seemed to see a behemoth like a meat sac flying backwards under the combined blow of sour saliva and the puppy's claws. The shaking of the tunnel just now was caused by the flesh sacs hitting the rock walls on both sides of the tunnel.

Now that the widening of the tunnel has stopped, the cavern that leads straight into the depths of the stratum has become more and more spacious, and now it has expanded from half a meter in size to 8 meters in diameter, which is enough to accommodate several people to move side by side.

Of course, the meat sac has another task - excretion. Used to expel acid gases, and the three of them walked this way. To put it in disgusting words, it is no less than the drain pipe of a flushing toilet.

Tang Fang didn't dare to tell Zhou Ai about this matter, because he didn't know how the girl would react, women love cleanliness, so it was better for him to let this matter rot in his heart.

Because there was no sour water in front of him, he withdrew the Zerg unit. Replace it with 2 Immortals and 3 Zealots to clear the way in front, so that even if the frightened flesh sac organ kills a return gun, it will definitely not be good to face the Immortal's phase jamming cannon. He was one kilometer behind the vanguard with Zhou Ai and Roy, so that he could have enough time to react in the event of a crisis.

Continuing to move forward like this, according to the message from Emma, the three of them have gone deeper than 40 kilometers underground, and it seems that there is still a long distance ahead.

Tang Fang could only endure on the one hand and continue to move forward, on the other hand, he was distracted and paid attention to the situation of the pioneer in front of him, Zhou Ai and Roy did not say a word, and honestly followed behind him.

The tunnel contains a high concentration of acidic residues, as well as sulfide, methane and other fatal gases, but fortunately, the harsh environment protective clothing completely blocks the contact between the human body and the external environment, so that the three people can withstand it even if they feel a little depressed.

After walking about 2 kilometers forward, a message came from the fanatic, which was not far from the exit of the tunnel, which made Tang Fang breathe a sigh of relief and at the same time was a little puzzled, wondering why the meat sac-like thing had let them down.

He thought of an allusion to a wolf beating a wolf with a hemp pole and being scared at both ends.

The so-called hemp stalk is a kind of plant stalk that looks very hard, but is actually easy to break and break, people take it to drive away the wild wolf, and they dare not really fight, because the hemp stalk will be broken when the stick goes down, so it can only bluff, and the wolf does not know what it is, and is also afraid, so there is such an allusion.

After hiding underground in the "Akron" for so many years, it is normal for the meat sac to suddenly encounter such a fierce creature as cockroaches and puppies, and it is normal to feel dazed and frightened.

Thinking about the subtlety, he no longer hesitated, beckoned the two of them to walk quickly, and rushed to the exit of the tunnel after a while.

Said to be an exit, in fact, more like a cliff, the entrance of the cave is open on the surface of a stone wall, thousands of meters high from the ground, Tang Fang used C-20A to shine on the bottomless abyss below, and also shine on the huge stalactites that fall on the left and right sides of the cave, some exquisite and transparent spars reflect the light of the stars, and occasionally water droplets fall, and it took a long time to hear the sound of falling in the stone depression and breaking.

Instead of immediately looking for a way down, he summoned an observer to scan the area of the space structure in front of him, draw a topographic map and synchronize it to the central computer of the harsh environment protective suit.

Different from the large cavity of the Planet 5 stratum, this area is more open, more than 1,000 meters in front is an open land, with an area of more than ten square kilometers, it is actually just a platform protruding from the rock wall, and the place thousands of meters below the platform is the real underground space, and there is a wide underground river flowing quietly at the bottom.

"It's so high."

Roy poked his head out to look at the dark abyss below, his voice trembled a little, he didn't have a fear of heights, but he was a little afraid of the dark, especially this kind of eerie environment that can be described as hell.

Tang Fang patted him on the shoulder for comfort, and without saying anything, he summoned a king worm, rolled up the bodies of the three of them and slowly flew to the open platform diagonally above.

During the flight, Roy hugged the long tentacles of the king worm, for fear that one would accidentally throw him down, how long would it take to fly at an altitude of thousands of meters before falling to the ground and falling to his death...... As many people say, death is not actually scary, what is scary is the process of waiting for death.

Tang Fang felt a little funny, he could only summon an iron crow to give half a big boy and Zhou Ai a strong courage, although the combination of Nighthawk's body length of more than 30 meters and a super-powerful searchlight was more suitable for such an abyss environment, but considering the storage of meat sac creatures, he finally chose the iron crow, at least the 12mm electromagnetic cannon can provide additional fire cover. (To be continued......)
