Republic of China: German-equipped divisions massacred as warlords guarded the nation's borders

"I want the whole world to know that from this day forward, who calls the shots in this part of the East China Sea!"

"Yes, young marshal!" Su Guiying straightened her back, her eyes flashing with fanaticism, and suddenly turned and rushed towards the telegraph room.

……

East China Sea, 30 meters underwater.

In the cold, dark depths of the ocean, thirteen black, cigar-shaped steel behemoths, each with a displacement of 1,200 tons, float silently in the ocean currents, like a pack of wolves holding their breath.

The U-93-class ocean-going submarine, a groundbreaking deep-sea weapon directly obtained through this system, boasts a streamlined hull that blends perfectly into the darkness. At its bow, four 533mm torpedo tubes are already filled with seawater, ready to unleash a deadly, passionate kiss at any moment.

The U-931 flagship, inside the cramped and oppressive command center.

The red combat indicator lights flashed wildly, making the faces of everyone in the cabin appear as if they were covered in blood.

The air was thick with the pungent smell of diesel fuel, sweat, and steel. In this space of less than a few dozen square meters, dozens of crew members were huddled together at their posts. Everyone subconsciously held their breath to the limit, and the entire cabin was so quiet that only the faint hum of the electric motor could be heard.

German ace submarine captain Heinrich gripped the periscope handles tightly with both hands, pressed his eyes against the eyepiece, and breathed heavily. As a sea monster who had sunk tens of thousands of tons of enemy ships in World War I, his blood was boiling at this moment.

In his view, the sea was still raging, but in the center of the reticle, the massive, mountain-like battlecruiser "Kongo" was arrogantly cutting through the waves. Its huge turrets looked incredibly menacing in the moonlight.

"Beep beep beep—beep beep!"

The telegraph operator removed his headset, whirled around, and his voice trembled with extreme excitement: "Sir! Top-secret telegram from Longhua Command! Young Marshal's order: If possible, leave no survivors! Annihilate the entire enemy fleet!"

Upon hearing this, a crazed and cruel smile finally cracked across Heinrich's granite-like German face.

He had been waiting for this moment for far too long.

"Gentlemen!"

Heinrich turned to the Chinese submariners and German veterans in the cabin, their faces filled with fanaticism. He ripped open his collar and roared in broken Chinese mixed with German accents, "The Supreme Commander has given the order! Your swords are sharpened. Now is the time to let the enemy's blood stain the sea! I will show these arrogant Japanese what true naval art is!"

"The hunt begins!"

Heinrich whirled around and roared at everyone in the cabin, "Wolfpack tactics, begin!"

"Open the water injection valves for torpedo tubes one through four! G7e electric torpedo, prepare to set parameters!"

"Torpedo tubes one through four are fully filled with water! Pressure is normal!" A Chinese adjutant loudly repeated the command, precisely pulling open each of the red valves.

"Attention all boats! Adopt the highest level of wolf pack tactics, strangulation formation! Boats one through four, lock onto the four enemy destroyers on the left flank! Boats five through eight, lock onto the four enemy destroyers on the right flank!"

"Boats number nine and ten, lock onto the enemy's left flank heavy cruiser!"

"Boats 11 and 12, lock onto the enemy's right flank heavy cruiser!"

"Our submarine is in charge of the main course—the battlecruiser Kongo!"

"After assessing the battle results, if no further attack is needed, concentrate all firepower on the battlecruiser Kongo!"

Every instruction from Heinrich was transmitted swiftly and precisely to the command rooms of the other twelve U-boats via advanced underwater acoustic communication devices.

Thirteen submarines, like an extremely precise killing machine, silently adjusted their posture underwater, aiming their bow torpedo tubes firmly at the unsuspecting prey on the surface of the sea.

"Depth 35 meters, heading 045! Electric motor running at low speed!"

"Firing data for all tubes input complete! Fuze set to magnetic fuse, depth set at five meters!"

"Three kilometers away!"

"Two thousand five hundred meters!"

"Two thousand meters! Entering optimal firing range!"

Heinrich took a deep breath and slammed down the launch button.

"emission!"

"Pfft! Pfft! Pfft! Pfft!"

With four muffled thuds of compressed air being ejected, the massive U-93 submarine even experienced a slight jolt in the water due to the instantaneous reduction in weight.

Immediately afterwards, the remaining twelve submarines also opened fire.

Twenty-six G7e-type electric torpedoes, loaded with high-explosive materials, plunged into the deep sea like cannonballs. The electric motors instantly reached their maximum speed, propelling these black reapers at terrifying speeds exceeding forty knots, silently hurtling towards their respective targets in the pitch-black water.

There was no roar of diesel engines, no huge bubbles from gas exhaust.

Only the absolute chill of death brushing against your back.

On the sea, the battlecruiser Kongo.

Yamaguchi Tamon was holding a cup of sake, listening to traditional Japanese music playing from a gramophone, his face full of hope for achieving unparalleled military exploits.

And in the sonar room on the ground floor.

Two Japanese sonar soldiers were idly wearing headphones, listening to the monotonous sound of the seawater flowing.

"Sir, you're being too cautious. This is the deep sea. How could the Chinese submarines possibly be this far?" A sirens yawned and complained. "Besides, even if they had submarines, how could they possibly have submarines that reach the open sea? Furthermore, we have eight destroyers escorting us. One depth charge per destroyer would blow them to pieces."

"Exactly, and if a torpedo were launched, there would be huge white bubble trails on the sea surface; the lookout would have sounded the alarm long ago..."

A voice sirens soldier jerked his head up and screamed in terror, "Torpedo! Torpedo coming!"

However, before he could finish speaking...

"laugh--"

Suddenly, a very faint, eerie hissing sound, like a venomous snake flicking its tongue, came through the headphones.

This was a sound they had never heard before, completely different from the deafening propulsion noise of a steam-gas torpedo. It was soft and subtle, yet carried a chillingly deadly threat.

The soprano was stunned for a moment, then his face turned deathly pale, and he turned the volume up to the maximum.

"Buzzing—"

The next second, that extremely faint hissing sound instantly intertwined into a dense chorus of deathly cries!

Not one! Not two!

Instead, there were a total of twenty-six high-frequency vibration sources, which were approaching the entire fleet from all directions at an extremely terrifying speed!

"Fish, torpedoes!!! A large number of torpedoes!!!"

The sonar soldier screamed in utter terror, scrambling towards the alarm and pressing the red button down hard.

"Waaaaah—waaaah—"

The piercing sirens of air raid sirens and anti-submarine warfare instantly echoed through the night sky above the entire Japanese fleet. The fleet, which had been sailing quietly, erupted into chaos. Countless Japanese sailors were jolted awake from their sleep, stumbling and scrambling to their battle stations in their underwear.

Inside the bridge of the Kongo, Yamaguchi Tamon suddenly jerked his sake cup, spilling sake all over the floor.

"What happened?!" he roared.

"Commander, we've detected a large number of torpedoes approaching from all sides! The number... the number is uncountable! They're coming from all directions!"

The staff officer was so terrified that his voice was trembling!

Those were dozens of torpedoes!

Even if they were arrogant, the Kongo was still just a battlecruiser, not a battleship, and certainly not a divine weapon of Amaterasu...
