Minnow adjusted the power output to the limit, the spare magic core supplied energy to the propeller at maximum power, the airtight compartment discharged the seawater, and the "jellyfish" soared, even when it was operating at full capacity, the A-13 still ran smoothly, the air flow through the valve made a slight whining sound, the pointer in the instrument panel jumped, and all the values were within reasonable range.

There is no doubt that this is indeed a sophisticated deep-diving machine.

However, the underwater shock caused by the detonation of the cockapace whale has a knock-on effect, and the sea water is an excellent conductor of sound, and the loss of sound wave transmission is less than in the air, allowing the sea tribes to discover this target at greater depths and distances.

Soon, a large number of fish swam to the sound.

"Hell." Mino stared closely at the operating table that displayed various working conditions, and suddenly cursed: "Lost lock...... Among these damned sea monsters are spellcasters. ”

As a successful graduate of the Imperial Military Academy, even ordinary people are required to have the knowledge and ability to discern magic, and when Jellyfish A-13 loses its direction and the horizontal axis cannot be calibrated, Mino immediately senses that something is wrong and tries his best to escape.

But it was still a step too late, and when he reached a depth of 800 meters, the submersible could no longer float, and a spellcaster built a puzzle lock to seal the sea area, blocking his way.

"A spellcaster has been found in the Sea Clan, and the sea area above A-13 has been blocked, please ask the command to check."

He reported that with his eyes fixed on the rapidly approaching fish in the surveillance device, it appeared that the sea tribes were working together to see themselves as their inevitable prey.

Mino gritted his teeth, he knew very well that he was waiting for a dead end, and he didn't have time to wait for the response of the command, so he simply decided to give it a go, and instead of trying to float, he manipulated the deep submersible and began to sink rapidly

- The oxygen tank is an enchanted equipment, which contains far more oxygen than expected, which can support his underwater activities for a long time, if he can sink to the bottom of the sea to avoid the sight of the sea tribes, and then float up after the fleet is cleaned, there may be a chance to survive.

The feeling of overweight suddenly disappeared, followed by a sense of weightlessness, Jellyfish A-13 was falling to the bottom of the sea, the depth gauge was rapidly rising, Mino knew very well that if he was not in the jellyfish, the terrible water pressure of the deep sea would kill him directly, and only a legendary warrior could survive in this environment.

"Jellyfish A-13, the Storm is trying to unlock the Mystery and is expected to crack it in a minute, please prepare to return." At this time, it was not until the voice of the correspondent in the channel that it was too late.

"I'm sinking to hide from the Sea Clan." "If all goes well, I'd like to return to the ship after the cleaning is complete," Mino reported. ”

There was silence on the other end of the communicator, apparently the command also understood the current situation of A-13, and after a pause, the channel responded: "Roger, the Shuofeng will drop ten Thunderfish to assist you and keep in touch." ”

"Thunderfish" is an underwater precision-guided weapon, its prototype is the self-detonating puppet fish of the Southern Empire, its remote-controlled timing and fixed-point detonation characteristics won the favor of Caesar, so after the painstaking research of the Black Wing Weapons Research Institute, the goblins added more industrial attributes to it after repeated improvements, making it more suitable for mass manufacturing and production, and renamed it "Thunderfish". Now massively equipped with the Imperial Navy's fleets, the Navy called it the "Shadow Killer" to describe its small, nimble and powerful nature.

"Understood." Hearing the arrangement of the headquarters, Mino's heart was a little more steady.

After the Shuofeng finished cracking the lock, the Thunderfish soon arrived at the Jellyfish A-13, and the submersible continued to sink, 1500 ...... 1800…… 2200……

It stands to reason that the sea tribes should all stay in the shallow water area now, waiting for the opportunity to attack the fleet at any time, but what Mino didn't expect was that as he gradually sank to the bottom, the sea tribes that emerged around him not only did not decrease, but tended to increase, and the deep sea, which should have been pitch black, gradually became brighter, and there was a clear light outside the observation window, and the color of the water was like flowing silver light.

Thunderfish exploded around the submersible one after another, fending off the growing number of incoming demon sharks and armored whales, and through the naked eye, Mino saw a huge crimson squid waving its tentacles, the ends of which were glowing with magic.

Obviously, it was this monster that had built a maze in the sea below the fleet from a vast distance.

Mino became restless, and cold sweat broke out on his forehead.

The "Boom, Bell, Bell...... submersible was struck, and the ten thunderfish that accompanied him in the sinking were long gone, and here he saw his original mission target, a school of spearfish, those sea tribes with long dart-like strange mouths, slender bodies, and extremely fast swimming speeds, flashed past his field of vision.

"Knock~" spear swordfish's stinging.

The deep submersible shook violently, the iron frame on the surface made a tooth-sour sound, the surging water slapped on the shell of the jellyfish, the entire sea area was stirred by fish, the school of gunswordfish flew across the field of vision, huge armored whales appeared one after another, and one after another demon sharks also entered the monitoring range.

The dark steel canisters installed on both sides of the jellyfish A-13 have been damaged, and the steel walls of the deep-sea oxygen tanks prepared by the empire for the jellyfish are several centimeters thick, and there are enchantment measures, but it is still the most vulnerable place of this deep-sea weapon, unable to block the stabbing of the spearfish fish, and after being hit by the attack, several openings were torn open, and the oxygen escaped from the cracks.

Mino suddenly realized why he had just been caught in a siege, a cocked whale and a demon shark...... Countless sea tribes arrived immediately, and even had the help of a spell-casting squid.

It turns out that this is the gathering place of the Sea Clan.

The slender figure swam in the clear water, its long tail swinging slowly, and it moved calmly, but anyone could tell that it could burst out at an astonishing speed at any moment, rushing towards its target like an arrow, it was a giant demon hunting shark, covered in a miserable white bone shell, it was hard to imagine such a creature in the sea.

As soon as it appeared, the other sea tribes consciously avoided it, and it looked like the leader of the demon shark group.

"Click......"

The leader of the demon shark stared at the jellyfish, it quickly pounced, opened its mouth to bite the tail of the submersible, shook its cheeks and tore it, the jellyfish shook violently, the propeller made a cracking trill, after a while, it released its mouth and threw the submersible away, and threw it to the sharks waiting next to it, they teased as if they were competing for their prey, constantly competing and biting.

Leakage of oxygen supply tank, leakage of watertight chamber, transmission system failure, power failure...... The alarm lights on the main console flickered like crazy, and Mino knew that the submersible had lost the ability to return home.

"A-13, we have received a distress signal from the submersible, please report your condition." A hurried voice came from the communicator.

"It's fine." Mino's simple response, and then unilaterally closed the contact with the command, at this time, he guessed that these sea tribes were probably relying on sound vibration to locate their location, so he fumbled to cut off the power source, and closed all the valves, leaving only the magic pattern outside the jellyfish hidden, like a stone to continue to sink.

Although he couldn't return, he wanted to do something more before he was completely torn apart.

3100…… 3400…… 4200…… Light shone through the porthole, and he saw rows of deep-sea fishmen, sea dragons with sharp mouths, heavy acid squid oozing venom, and many other species that he could not name.

The hands of the depth gauge swayed, the jellyfish A-13 was hovering in the deep sea with difficulty, tilting slightly, the lights on the instrument panel flickered for a moment before all went out, the flickering magic core was no longer functioning, and the cockpit was filled with the sound of "whining". Minnot knew that the original submersible of the Blackwing Empire had done everything it could.

Now, it fell asleep peacefully.

He slumped into his seat exhausted, his lack of oxygen making it difficult for him to move, he groped sluggishly, found the cockpit's independent single-line contact, and dialed: "Shuofeng, this is A-13......"

As if he had understood his situation at this moment, the quiet and indifferent correspondent's voice seemed to become gentle: "Received, please speak." ”

"I've entered the hinterland of the Sea Clan, please locate my depth coordinates, clean the target, repeat, clean the target."

There was silence for a moment, and the voice on the other end of the communicator rang out: "Communicated to Command. You ......"

Mino, who was starved of oxygen in his brain, could no longer hear the other party's response clearly, he squinted, and said in a daze, "I may not be able to go back this time, you ...... To refuel. ”

“…… Good. ”

"For the Empire."

"For the Empire."
