You were tasked with guarding the Sihang Warehouse, and you brought out a Tiger tank?

The Japanese fleet originally intended to use its agility to evade artillery fire, but Lin Feng's inland river fleet charged forward like a pack of mad dogs and relentlessly pursued them.

LCS fire support boats and PT boats weaved, separated, and engaged in close combat with the Japanese fleet, forcing the Japanese gunboats to slow down and even disrupt their formation in order to avoid collisions.

This provided the Huangshan Fort with an excellent opportunity for fixed target shooting.

"boom!"

The largest gunboat in the lead, the "Hira," had already been hit by a barrage of fire from the LCS fire support ship, causing leaks in its waterline and reducing its speed to a snail's pace.

Just then, death arrived.

A 240mm high-explosive shell struck the front of its hull with precision.

"Thump—!!!"

For a moment, time seemed to stand still.

Immediately afterwards, a large fireball erupted on the surface of the river.

The immense explosive force tore apart the steel hull of the 300-ton gunboat.

To everyone's horror, the entire forward half of the Hira, along with its main gun turret and dozens of Japanese sailors, vanished instantly after the explosion.

A few seconds later, steel fragments and blood began to fall from the sky.

The remaining stern of the boat lost buoyancy and, like a rock, its rear end sticking up, slid into the rolling Yangtze River within seconds, leaving behind only a huge, bubbling whirlpool.

"Good, well played."

The people who were fleeing by boat on the river cheered when they saw this scene.

The fate of the other ship, the Baojin, was not much better.

It was hit by concentrated fire from multiple 88mm guns on the Huangshan Fortress, leaving its superstructure riddled with holes and its bridge half-shaved off, resembling a broken honeycomb briquette.

Just as it was trying to turn and escape, a PT torpedo boat came riding the waves.

"Da da da da da—"

The 20mm Oerlikon cannon on the bow opened fire wildly, and the two Japanese armed motorboats that tried to rush up to stop them were blown up by the dense rain of bullets before they even got close, exploding into two brilliant fireballs on the river.

The PT boat moved as if it were in an empty field, quickly approaching the side of the Baojin ship.

"Ready—Fire."

With a roar, the captain slammed the launch handle down.

"Thump! Thump!"

Two Mark 8 torpedoes fell into the water, splashing up white spray.

Immediately afterwards, the propeller at the tail began to spin wildly, leaving two straight white trails on the water's surface.

Like two dragons crossing the river, they rushed at high speed toward the Baojinhao, which was turning sideways and exposing its vulnerable flanks.

"Torpedo, starboard torpedo."

The Japanese captain was terrified and frantically tried to turn the rudder, but it was too close.

"boom!!!"

A muffled, loud explosion came from underwater, and the entire river surface seemed to tremble.

In Lin Feng's telescope, the unfortunate Baojin looked like a sugarcane that had been cut in half.

A massive column of water shot skyward, completely tearing the middle section of the ship apart.

The boiler experienced a secondary explosion, with flames shooting into the sky.

In just over ten seconds, the Japanese's prized inland river gunboat broke in two and sank rapidly.

All the dozens of Japanese crew members on board, plus the unfortunate captain, didn't even have a chance to jump overboard. They all perished with the warship, and not a single one escaped.

"Well done!"

Lin Feng put down his binoculars and stomped his foot hard.

The perfect coordination between the artillery emplacements and the river fleet effectively repelled the Japanese's aggressive surface attack.

The river was littered with the wreckage of Japanese warships and floating corpses. The remaining Japanese boats, seeing the situation was dire, turned tail and fled, never daring to approach this deadly water again.

However, the Japanese did not give up.

Unable to penetrate the river, they vented their anger on the artillery positions.

"Buzzing—"

In the sky, several Japanese planes discovered that the anti-aircraft firepower at the dock was too strong, so they turned around and swooped down towards Huangshan.

Lin Feng saw the Japanese planes turn around and immediately knew what the Japanese were up to.

He hurried up the stairs and ran to the top of the gun emplacement.

As the river defense fortress was designed with the help of Hans's consultant, the top of this huge reinforced concrete building naturally had positions for anti-aircraft weapons.

However, the Nationalist government has never been willing to spend money to purchase anti-aircraft guns, so the gun emplacements are now empty.

Lin Feng decisively spent his exchange points to purchase four basic anti-aircraft gun units on the spot, and then upgraded them all into Flak 38 quadruple 20mm anti-aircraft gun squads in one go.

"Black Card Incident, Banzai!"

In the sky, the Japanese pilots did not notice the several black dots that suddenly appeared on the top of the gun emplacement.

He just yelled fiercely in the airport to bolster his courage, then pushed the control stick down to lower the nose of the plane, preparing to drop the bombs.

"Fire!"

"Sizzle sizzle sizzle—"

At the top of the turret, four quadruple machine guns fired simultaneously, their sixteen barrels spitting out long tongues of fire.

A dense hail of bullets instantly wove a deadly net over the gun emplacement.

The Japanese pilot, who was preparing to drop his bomb, was instantly dumbfounded.

"What?! How can this cannon perform magic tricks?!"

He clearly remembered that when they bombed this place a few days ago, there were only two machine guns here. How come so many anti-aircraft guns suddenly appeared?!

Before he could react, a barrage of 20mm high-explosive rounds swept across his aircraft.

"Ping pong!"

The cockpit window was shattered, and the Japanese pilot was instantly riddled with bullets.

The first few planes were either shot down in mid-air or lost control, trailing black smoke as they crashed into the cliff below the gun emplacement, exploding into fireballs.

The remaining Japanese planes were terrified by the sudden and intense firepower. They hurriedly pulled up their noses, dropped their bombs, and fled, not daring to get any closer.

-----

In the middle of the river, on a strange boat that is speeding toward the north bank.

Colonel Wei Zhen, the former commander of the Huangshan Fort, was sitting in the cabin of this ship, his hand resting on the cold steel plate, his expression extremely interesting.

As a naval officer, he has spent his entire life dealing with ships.

From old-fashioned wooden-hulled gunboats to imported torpedo boats, he considered himself to have seen the world.

But he had never seen or even heard of the ship beneath him.

The ship has an extremely ugly design, resembling a large, square box. The bow is a huge steel gangplank, and the hull is also made entirely of steel.

But this ugly thing is surprisingly steady when it runs.

The diesel engine roared with a deep, powerful sound, propelling the iron behemoth, fully loaded with dozens of officers and soldiers and a large amount of supplies, across the turbulent Yangtze River as if it were flat ground.

"What...what kind of ship is this?"

Wei Zhen couldn't help but reach out and tap the gunwale, making a crisp, metallic sound.

"All steel plates? That's so extravagant!"

He turned to look at the stern of the boat.

There, two soldiers from the Provisional 8th Army were skillfully operating two .30 heavy machine guns.

"Da da da da da!"

A hail of bullets rained down on the sky, forcing a Japanese Type 95 carrier-based fighter jet attempting a sneak attack to pull up in a sorry state.

"Wow, even transport ships are equipped with such formidable anti-aircraft firepower?"

Wei Zhen was utterly shocked.
