Before Chen Jianhong's words fell, the submarine suddenly fell diagonally downwards as if it had received some huge suction, and for a while, everyone only felt that it was falling rapidly, as if falling straight from a cliff into the abyss.

"Report, the hull is not controlled, the power is normal, the operating system is normal, the power is normal......" A series of reports came out from the control room, and the lieutenant's anxious voice was changed tone.

"Sea cliffs?" A word immediately came to everyone's minds, but then they all shook their heads in denial!

In the vast ocean, sea cliffs are the most dangerous enemy of submarines.

The seawater cline is also known as the "hop layer" or "leap layer". A thermocline is an aqueous layer in which seawater parameters change significantly with depth. It refers to the water layer in which the temperature, salinity, density, and sound velocity of the sea water change abruptly or discontinuously in the vertical direction.

The thermocline has a positive effect on underwater communications and concealment of submarines. If the seawater thermocline is less intense, the upper depth is deeper, the thickness is larger, and the stability is more durable, irregular acoustic reflections will be formed, which will greatly reduce the combat effectiveness of anti-submarine sonar and cause difficulties for anti-submarine operations.

In battle, the sea water cline is more suitable for submarine covert action, and the submarine will try to find the sea water cline in the operation to conceal and wait for attack. When a surface ship detects a seawater cline under the water, it will usually quickly break away to prevent the decline of its anti-submarine capability, and the enemy submarine will use the cline to make covert attacks.

However, if the seawater thermocline is a state of high density in the upper layer and low density in the lower layer, a negative density gradient jump layer is formed, and the buoyancy of the seawater decreases sharply from top to bottom, which is called a "submarine cliff".

Most conventional submarines have an effective diving depth of 300 meters, and when the submarine falls below the safe diving depth uncontrollably, it will be destroyed by the huge seawater pressure, resulting in a wreck.

Once it encounters a cliff on the bottom of the sea, the destruction of the boat and the death of people are almost inevitable. In the depths of several oceans around the world, I don't know how many submarines and bones are buried because they have encountered a cliff on the bottom of the sea.

Twenty years ago, a conventionally powered submarine of the Republic of China once encountered a "submarine cliff" on the Pacific Ocean, and the officers and men of the whole ship reacted quickly and worked together to save the cliff within three minutes, which became a shocking miracle and was directly awarded the collective first-class merit. After his captain was awarded a first-class meritorious service, he ushered in a rapid promotion.

However, the "submarine cliff" generally occurs in the depths of the ocean far away from the mainland, and the current location of the submarine is in Kyoto Bay, although it is known as the depth of the water and the port is wide, but the maximum water depth is only about 40 meters, near the Kyoto Port wharf, the maximum water depth is only less than 20 meters, and there is no possibility of producing submarine cliffs.

And the feeling of the current submarine is not that it is falling in free fall, but that it is pulled by the huge suction force of the black hole and falling diagonally downward!

Chen Jianhong rushed out of the cabin and stumbled towards the control room. Several team members looked at the rapidly rising sea water outside the porthole, and their faces were a little ugly.

With their current physical strength, not to mention the sea water tens of meters deep, even if it is more than a kilometer deep, it can support it, but the key problem is that Kyoto is not only one of the largest ports, but also the capital of the Jeppen Empire! It is not known how many ships come in and out every day, and once the submarine is damaged, it is almost impossible not to be detected. And a special operations submarine of the republic appeared here, and even if you think about it with your ass, you will know that there are special operations personnel who have infiltrated!

If such a situation happens, even if all the personnel land safely, it means that this mission, which has been covered by countless big actions in advance, and the headquarters does not know how determined and persuaded how many people can finally carry it out, will face the fate of failure from the beginning!

Lei Dong nervously released his divine sense, probing all possibilities. Although the speed and enveloping range were several times smaller than on land, under the desperate urging of the thunderbolt, a familiar shadow suddenly flashed hundreds of meters away.

A wolf-like, more than ten meters in diameter of the blood basin mouth, wide open, a dragon-like water column, spinning towards this blood basin mouth rushed quickly, in the waterspout, countless fish, shrimp and crabs, countless seaweeds, countless unknown sea creatures, and even a few white sharks, like a bird falling into a net, fluttering civilians struggling, but how can not get rid of the huge suction and high-speed rotating water dragon.

And behind the infinite sea creatures, the six-bladed propeller of the 098T pocket submarine is buzzing rapidly, desperately rushing left and right, trying to get rid of this deadly suction!

Gourmand!

Lei Dong's divine sense condensed into a line, slammed into it, and whispered softly: "Damn foodie!" ”

As soon as the thunderous divine consciousness touched the huge mouth, the gluttony was already alert, and a powerful divine consciousness swept over.

"Huh?" In just a blink of an eye, a gluttonous voice sounded in the sea of thunderous knowledge, "It's you little Taoist again?" ”

The next moment, the glutton's big mouth suddenly closed, and scolded fiercely: "You dare to disturb the gluttonous uncle's meal, you are simply unforgivable!" Then he seemed to think of something again, and put down a sentence: "Go back and ask you to settle accounts!" Only a body with a big mouth remained, and the four small short legs slashed a few times, and disappeared in an instant.

Just when the gluttonous mouth was closed, the waterspout with a diameter of more than ten meters "banged" and scattered, and tens of millions of sea creatures suddenly lost their restraints, and with the scattered water waves, they flew away dizzily, and after a long time, they seemed to have returned to their souls and fled in a hurry.

At this moment, the pocket submarine suddenly regained its freedom, stopped sinking, and began to slowly float under the control of Chen Jianhong and the lieutenant.

"Whew-" Lei Dong let out a long breath, "Damn, I almost killed Lao Tzu!" ”

didn't know that Chen Jianhong, who was in the control room, secretly glanced into the cabin, and his eyes were full of shock......

――――――――――――――――――――――――――――――――――――――――――――

June 5, 2030, 11 p.m.

The capital of the Jeppon Empire, Kyoto's Chisei International Airport is still brightly lit.

This is the largest airport in Kyoto and one of the top three airports in the world. Every day, people from different countries and colors go to all over the world through it.

It's a bustling and bizarre area.

The rows of commercial buildings and entertainment venues in the vicinity, and the bustling flow of people coming and going, fully prove how prosperous this area is.

And the strange young women who wore and walked in the crowd, and the signs that secretly displayed the words "Aid and Communication", fully illustrated how depraved and chaotic this place was.

In front of Terminal 1, a Wuling business car was parked, a middle-aged man, dressed in a black suit, was carrying a large suitcase from the car, and a woman dressed in traditional clothes, holding a boy about seven or eight years old, followed closely behind the man.

The woman had a meek smile on her face that is characteristic of traditional Jeppen women, but if you look closely, her smile is a little forced. And the boy in his hand jumped up and down without a moment's rest.

The man checked in silently, received the two boarding passes, walked to the security checkpoint with the woman and the boy, and handed the suitcase in his hand.

"I'm sorry I can't travel with you." The man bowed deeply to the woman.

The woman bowed the same, still with that meek and reluctant smile: "Zhongshan-kun, is it really not......

The man was silent for a moment, shook his head gloomily and said, "Keiko, you know, he will grow up the day after tomorrow...... You guys...... I've got in touch, and when you get to Hanking, my friend will pick you up at the airport, remember, my friend's surname is Yin. ”

Keiko nodded, still looking docile. The man squatted down and gently held the little boy's smiling face with both hands, "Renxiao, remember, you must listen to your mother, you know?" ”

The little boy puffed up his chest and shouted: "I remember my father, I will be obedient, and I will protect my mother!" ”

The boy's immature voice made the man almost cry, and he took the child in his arms violently, and it took a long time before he let go of him, stood up, and said to the woman, "All right, go in." ”

The woman nodded, walked to the security check, passed the security check, walked along the long passage towards the departure hall, the little boy kept turning around, waving to the man: "Goodbye, Dad—"

"Goodbye Renxiao......" The man waved his arms mechanically, looking at his wife and son who were gradually disappearing from sight.

My wife, who is far away, has been loving herself so wholeheartedly since she was rescued in the earthquake fifteen years ago, and even after knowing that she is a notorious gangster, she has never changed her attitude and love for herself. And myself, from being cautiously guarding against her to paying sincere love, how complicated is the mental journey during this period? And how much joy and joy has that lovely son brought to himself since he came into the world?

However, they don't know their true identity, let alone know that this may be the last time the family will meet......

The man shook his head vigorously, forbidding himself to think about it again, but when he finally turned around, two lines of tears finally couldn't help falling anymore.

However, as he walked out of the departure hall, the tears on his face had dried, and his gaze had become serious again, and his black leather shoes stepped on the hard ground illuminated by the ceiling light, making a very rhythmic crackling sound, which seemed to be his steps so firm.

From a distance, he had already seen a young man leaning on the front of his seven-seater Wuling business car smoking a cigarette.

The man strode over, his eyes shining. Because he knows that he will usher in the most brilliant bloom in his forty-five years of life!
