At the bottom of the sea, cold and silent.

A large black submarine passed by, extremely fast, like an ancient monster, disturbing the calm current.

Time passed quickly, and it was already twelve o'clock in the afternoon.

Su Xia looked solemn, stood with his hands in his hands, stood in front of the console, didn't know what he was thinking, motionless, had been standing for several hours.

At this moment, they have left the southern seas.

According to the map information, the current Nautilus is very far from land.

According to Su Xia's request, the distance between this submarine and the land is still increasing, and it is striving to enter the central area of this ocean as soon as possible.

This ocean is in the middle of two continents, and the total area is close to the sum of the two continents.

The journey was relatively peaceful, with no mechanical creatures encountered, and no underwater monsters found.

The sea is vast, and every life is an isolated island adrift in the water.

After a while, Su Xia suddenly moved.

He frowned, sat down in front of the console, took out the submarine manual from the storage space, flipped to the place he didn't understand just now, and browsed carefully.

"I see, the technology of this submarine only supports submarines above 100 meters underwater.

In other words, although it can dive to a depth of 10,000 meters, if you want to launch a missile strike against the enemy, you still have to slowly float up to an area of 100 meters deep, and during this period it is easy to be detected by local scouts in shallow water.

"In this way, this submarine is not perfect, the shortcomings are very obvious, is it possible that the technology of underwater launch does not have too many breakthroughs in the starry sky?"

Su Xia pondered for a long time, staring thoughtfully at the manual.

The structure of this submarine is very simple, in the middle is sixteen launch tubes, which can carry 192 missiles, but unfortunately the inside of the launch tubes is empty.

He is now looking through the manual, just to prepare for a rainy day, if he has the opportunity to get a missile in the future, he can give a big gift to the mechanical family.

Su Xia thought for a moment and took out another book from the storage space.

This is the book that comes with the submarine manual, the title of the book is "Submarine Driving, From Beginner to Across the Seas", and the cover is a very sci-fi silver-blue submarine.

The content of the book is very crude, and it is not even as good as the manual, but it contains many practical examples, including how to save yourself in the face of various dangers.

Flipping through the book, the first page reads: "If your planet has an irresistible situation such as a war of destruction, a zombie crisis, a natural disaster, etc., and the land world is destroyed in one fell swoop, it seems like a good choice to go into the vast sea." ”

Zombie crisis?

Su Xia's eyes flickered, does a zombie that violates the conservation of energy really exist?

On the side, Sarah seemed to see what Su Xia was thinking, her eyes flashed, she pursed her lips and smiled, and said: "More than two hundred years ago, on a civilized planet in the Heinlyaine Star Domain, there was an outbreak of a virus called 'Crazy Death', which swept the entire planet in just a few years.

"It is an RNA virus that invades the neurons of the brainstem, cerebellum and other regions of organisms, causing patients to show symptoms such as madness, madness, biting, and screaming.

"Some patients die three to five days after infection, while others have a normal initial illness and develop ...... several months later."

Sarah narrated slowly, recounting the contents of her database, telling Susha about the state of the civilized planet.

The infected people of that virus are similar to the zombies in many science fiction movies.

If you really want to talk about the difference, most of the zombies in those movies move slowly, while the patients infected with that kind of madness move extremely fast, are not afraid of pain, and bite people when they see them.

"And then?"

Su Xia became interested, and he was a little curious about the stories in this kind of star civilization.

Many stories contain the development of civilization, social changes, heroic deeds and other aspects, like bright stars, dotted with the vast starry sky.

"Later, a high-level civilization made a move, transferred all the remaining healthy creatures from that planet to another civilization star, and then released purification smoke on that planet." Sarah blinked and said.

"Purify the smoke?" Su Xia was puzzled.

"It's poison gas."

"Oh...... All dead, indeed purified. ”

Su Xia thought for a moment, and a picture gradually formed in his mind, that is, the entire planet was shrouded in terrifying poisonous gas.

Come to think of it, the so-called advanced civilization is not as advanced as imagined, and it can't even solve a virus, and in the end it can only be poisoned and killed.

The interstellar civilizations are vast, more than the sand in the sea, and there are countless of them, some of which are still in primitive times, and some of which are already able to cross the star field.

The "Seventh Empire" that Su Xia had always heard of was a super civilization that could span the star field, dazzling, and one of the most shining civilizations even in the vast sea of stars.

Hal often described the appearance of the interstellar empire for Su Xia, in his description, there is a starfleet, there is a brilliant scientific research civilization, the entire empire is in rapid development, and has even touched the threshold of another world.

"Captain, don't yearn for the stars too much, most civilizations are even inferior to the planet you're on now." Sarah said with a chuckle.

"It's just to see, to witness, not to enjoy life." Su Xia shrugged his shoulders, "Interstellar travel enjoys the process and exploration, not the result. ”

If you really want to enjoy life, with Su Xia's strong strength as a fifth-level creature, she can completely become a god of a primordial civilization planet.

On that kind of planet, if he shows the ability to control metal and kill people, he will become the god of steel or war.

"Captain, you think about it like that Dr. Agar when he was younger." Sarah said with a smile.

"Is the doctor still alive?" Su Xia's heart moved.

"I don't know, in my factory information, there is no information about him in the past few years, he seems to have disappeared, most likely ran to a certain planet to hide."

Sarah said that the Empire's law enforcement fleet could span the sea of stars, and it was so powerful that individual forces could not resist it at all.

As an interstellar criminal, the best option is to find a remote planet to hide.

Such a planet is preferably one that is not recorded in the Imperial Star Domain.

"Captain, the contents of this book in your hand are in my database." Sarah returned to the topic and chuckled, "If you don't understand, just ask me." ”

"Hmm."

Su Xia put aside other thoughts and began to flip through the book in his hand.

If you want to learn submarine operation technology, it is a very long process to start from scratch, and with Su Xia's current learning ability, it is normal to learn for three or five years.

Slowly, the submarine fell silent again, leaving only the dull sound of various instruments and equipment.

The time soon came to half past six in the evening, and the shadow of the sun was setting in the west, gradually sinking into the sea.

Another day is coming to an end.

Su Xia had been at the bottom of the sea for nearly forty hours, and he didn't feel the slightest discomfort, but he liked this closed environment a little.

When he was reading in the submarine, he didn't care about anything else, just concentrated on studying, and everything in the outside world seemed to have nothing to do with him.

This quietness is really rare.

Su Xia remembered that in the school library before, after ten o'clock in the evening, when everyone was almost gone, he would have this feeling of peace and contentment.

Before I knew it, it was the early hours of another day.

"Captain, it hurts your eyes to read for a long time." At three o'clock in the morning, Sarah suddenly opened her mouth to warn.

"It's not a long time, is it?" Su Xia raised her head, her eyes a little dry.

"It's already over the upper limit of your eye strain, and if you continue like this for a long time, it's easy to develop myopia." Sarah said.

"It doesn't matter, wearing glasses after myopia can add an elegant temperament."

"This ......"

Sarah opened her small mouth with a complicated expression, looked at Su Xia, and stopped talking.

She just didn't know that as a student who had gone through the college entrance examination, Su Xia had long been immune to this kind of high-intensity study, even if she read all night.

In this world, Su Xia's body has a very prominent advantage.

He doesn't need sleep!

Moreover, as a psionic creature, he can maintain mental concentration for a long time, and every minute is in a state of intense learning.

In the past, Su Xia had not discovered the strength of this advantage, but today he felt it.

"Time waits for no one." He shook his head and continued to browse the book.

After a while, Su Xia frowned slightly, always feeling that her current state was not perfect enough.

After thinking about it, he took out a bottle of precious sixth-order medicinal wine "Starry Sky Flow" from the storage space, and opened the lid of the wine bottle with a snap.

Suddenly, a rich aroma of wine mixed with fruity aromas escaped, filling the entire command cabin.

Su Xia took a deep breath, only to feel that his mouth and tongue were full of fragrance, and his whole body was light, and the whole person had a feeling that he was about to soar.

"It's worthy of a sixth-order medicinal wine." He sighed, "This wine can't enhance the body, can't strengthen the five senses, and has no amplification effect on spiritual energy, the only effect is to 'concentrate the mind' and make people enter a very mysterious state." ”

Su Xia stared at the wine bottle and thought for a moment.

Then, he took out a small wine glass and poured out a glass, and the fragrance in the command cabin was a little stronger again.

[The problem of slow update of new chapters has finally been solved on the app that can change the source, download it here.]

The wine has a soft blue color, with silver sparkles inside, like a swaying galaxy, and the mere look at it evokes a sense of calm.

Su Xia didn't think too much about it, picked up the wine glass, and swallowed the wine into his stomach in two sips.

"Gurgling ......"

He licked his mouth, but he didn't taste anything, only a very sweet smell.

The woman pharmacist who made this medicinal wine had warned Su Xia that she didn't need to drink too much at one time, otherwise it would be a waste.

Su Xia remembered the woman's words, did not greed for the cup, covered the lid of the medicinal wine, and quietly waited for the effect of the medicine to kick in.

More than ten minutes later, Su Xia suddenly felt a trance.

"This ......"

His heart moved, pressed his forehead, and in this moment of trance, a cool feeling suddenly appeared in his brain, as if all the trivial things were flying away, gradually disappearing in the depths of memory.

The whole mind instantly became a large blank space, as if it had become a blank paper.

Su Xia took a few deep breaths, and even his heartbeat stabilized a lot.

It's a strange state.

He didn't know how to describe it, the whole person became peaceful and peaceful, calm, the bloody killing not long ago was swept away, and the old things were shattered, which made him have a kind of artistic conception of dust for a while.

In the world in front of him, only he and the books he needed to read, everything else disappeared without a trace.

"I see......"

At this moment, Su Xia understood the preciousness of this sixth-order medicinal wine.

His ability to learn, in this singular state, can increase by at least 40%.

If he had taken this potion before he had deduced the recipe of the potion, he might have been able to create a new and extremely precious potion in a strange state.

It's no wonder that the Zero Tavern regards it as a priceless treasure, and it can't be exchanged for money at all, so it can only be exchanged for things and take out the treasures that make the Zero Point Tavern heartbroken.

Such a precious medicinal wine, he actually took a bottle to give as a gift.

But Su Xia didn't regret it, and did everything.

He opened the book in his hand, unhurried, calm, and deep-sighted, and began to browse again, slowly sinking into the world of the book, forgetting the passage of time again.

A few hours later, a bright morning sun gradually rose above the sea level.

Another day dawns to come.

The mech's hunt has lasted more than 48 hours.

The overwhelming air army, the imposing ground army, and the large number of undersea warriors are still in action, searching every inch of possible area.

"Masked Geek, where the hell is he?"

As a long time passes, endless amounts of energy are consumed.

At this dawn, even some of the creatures of the mechanical clan were a little dazed, not knowing what the outcome of this search would be.

How vast is the sea?

The difficulty of searching for a person in the vast sea is actually about the same as the difficulty of finding a needle.

In the past ten years, many warplanes and passenger planes have crashed into the sea for various reasons, but only a very small part of them have been found, and most of the rest seem to have disappeared, not even a single debris can be found.

"Drain it with him!"

"He's just flesh and blood, no matter how you say it, it's impossible to consume us!"

"The Sky Camp and the Earth Camp have joined the search, and the whole world is looking for him alone, unless he runs to outer space, he will definitely be caught!"

Dozens of hours of continuous hunting only confused a few mechanical creatures, but it inspired the arrogance of most mechanical creatures.

They don't believe that the masked monsters can escape!

The passage of time has also made the situation in the outside world a little more weird.

The neutral groups that had been arguing on major platforms before have not spoken much now, and seem to be waiting for a result.

The sun slowly became hot, driving out the shade of the sea, and then gradually dimmed, sinking to the other side of the sea level.

The evening of the third day arrived.

At this time, under the surface of the sea, at a depth of 10,000 meters, among submarines.

Su Xia, who was reading a book, was suddenly disturbed by Sarah's reminder: "Captain, I have discovered a very special area. ”

"What area?" Su Xia raised her head and blinked her eyes vigorously a few times, only to feel that her eyes were getting drier and dryer, and she had to put the book down.

"A crack in the ocean floor." Sarah replied.

"It's just a rift, nothing strange, right?" Su Xia got up from the chair and stretched, sitting for too long, her whole body was about to stiffen.

"At the edge of the rift, I caught a very special metal." Sarah said.

"What metal?"

"A metal often used in spaceship shells."

"Huh?"

Su Xia's heart moved, and he instantly thought of the wreckage of the spaceship.

The same metal, which had been found in the basement of the pharmacy, was one of Daddy's many collections.

Later, when the cyborgs searched the store, they found it and believed that it was a fragment of the ship's wreckage, and took the metal away.

In that forest in the southwestern mountains, there are similar metal fragments in the area where the wreckage crashed.

These fragments can also be found near the wreckage chasm in the Oasis camp.

"Sarah, is there a lot of this metal?" Su Xia's eyes flashed, and he immediately asked.

"There are quite a few, more than a dozen fragments have been found so far, and there should be more around the rift ahead."

"Is it ......?"

Su Xia took a deep breath, and the whole person was unsettled.

On this trip to the bottom of the sea, he had gained enough, first a large number of psionic pearls, and then a shipwreck treasure.

Now, is it necessary to harvest another piece of alien spaceship wreckage?

When did his luck get so good?
