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

BF-109 E-3 fighter jet

Exchange Price: 200 points

[Weapons: 2 x 20mm MG FF autocannons (wings), 2 x 7.92mm MG17 machine guns (nose)]

[Note: The pride of the Han Air Force, with its two cannons and two guns, could easily tear apart even bombers.]

"Yay!"

Lin Feng clapped his hands hard.

The BF-109 was the mainstay of the Han Air Force during World War II.

In this era, its speed and climb rate could easily outperform the Japanese Navy's Type 96 carrier-based fighter and the Army's Type 95 biplane.

Even against a mid-game Zero, the BZ tactic can put up a fight.

200 points isn't expensive. Once we have a stable base and build an airport, we can go on a rampage.

Seizing local air superiority will not be a dream at that time.

[JU-87 B-2 "Stuka" dive bomber]

Exchange Price: 200 points

[Weapons: 2 x 7.92mm MG17 machine guns (wings), 1 x 7.92mm MG15 machine gun (recoil)]

Maximum payload: 1000KG

[Description: A weapon of precision strikes. The piercing shriek emitted during its dive can drive enemies on the ground to madness.]

Lin Feng was overjoyed to finally have a Stuka; he could finally give the Japanese army and navy a taste of bombs.

[JU-52/3m "Junkers Grandma" Transport Aircraft]

Exchange Price: 400 points

[Carrying capacity: 18 soldiers or 2-3 tons of supplies]

[Description: Rugged and durable, capable of taking off and landing on rudimentary runways. A lifeline for surrounded or retreating troops, allowing for airdropped supplies or transport of the wounded.]

Transport planes have arrived, but Lin Feng estimates that his troops will have to retreat with the main army for the foreseeable future.

This thing won't be needed in the short term.

The Air Force has only unlocked these three types of aircraft. As for reconnaissance aircraft, carrier-based aircraft, medium/heavy bombers, etc., Lin Feng estimates that they will have to wait until they unlock Level V permissions.

After looking at the planes, he opened the [Surface Ships] interface.

Unlike airplanes that need airports to take off, the Jiangnan region is full of waterways, including the Yangtze River, and the warships on the water can be exchanged for immediate combat power.

[PT-103 class torpedo/gunship]

Exchange Price: 150 points

Displacement: 56 tons

【武备：4枚Mark 8鱼雷，2座双联装M2HB重机枪，1门20mm厄利孔机炮】

Speed: 41 knots (approximately 76 km/h)

[Description: A naval assassin. Incredibly fast, its wooden hull prevents it from triggering magnetic mines. On the Yangtze and Huangpu Rivers, it was a nightmare for Japanese transport ships and gunboats.]

Is it a White Eagle and not a Hans?

Lin Feng was slightly taken aback, then overjoyed.

This ship is a veritable firepower hedgehog, armed with a 20mm autocannon, four cannons, and capable of launching torpedoes. And the price is the same as the Panzer II tank.

Once you buy a few, you can immediately launch attacks along the dense network of waterways in Jiangnan, carrying out surprise attacks on the Japanese army along the riverbanks.

As for going into the Yangtze River, this boat is still too small; I don't know if it can be upgraded.

The other ship available for exchange is a transport ship.

【LCVP "Higgins Boat" Personnel/Light Vehicle Landing Craft】

Exchange Price: 60 points

Displacement: 12 tons

[Load capacity: Can transport 36 fully armed soldiers, or 1 jeep/small artillery piece, or 3.7 tons of cargo.]

Speed: 12 knots (approximately 22 km/h)

[Armament: 2 Browning machine guns, .30 caliber (7.62mm)]

[Description: Skilled in infantry ferrying and light supply transport, one of the key players in the Normandy landings. The iconic "victory ship" of the White Eagle in World War II.]

Isn't this the same boat that White Eagle soldiers were riding on when they stormed the beach in the classic movie?

Lin Feng smiled as he looked at the familiar icon.

With this, the Yangtze River will no longer be an insurmountable barrier. We'll rely on it to transfer the wounded and transport infantry across the river.

Moreover, this thing is small in size, so once it's on land, it can be towed by a truck or hidden in the reeds.

With these two types of ships, even if the land route is blocked, he can lead his troops and heavy equipment to fight his way out by water, or even cross the Yangtze River directly and escape the Japanese encirclement.

After reviewing the newly added redeemable units, Lin Feng looked at the relatively abundant redemption points in his account and began a frenzy of spending.

-----

Outside the tent, the wind and rain were gloomy.

Inside the tent, the flame of the kerosene lamp flickered, casting Lin Feng's shadow long and short.

He sat at the table, holding a pen in his hand, the white paper in front of him covered with formulas and symbols.

"Boats and planes aren't urgent for now. As long as we have the money, we can exchange them anytime. Buying them now would just be a burden, and we'd still have to find a place to park them."

Lin Feng muttered to himself, his pen tip making a heavy tap on the paper.

He knew the script for the next scene all too well.

"Great retreat" is a euphemism.

In reality, it was a rout that stretched for hundreds of kilometers.

Hundreds of thousands of troops were crammed onto narrow roads, their organization disrupted and command failing. Japanese planes were bombing overhead relentlessly, while pursuers were hot on their heels.

Upon arriving in Jinling, the situation became even more hopeless.

"My forces are too small to change the overall situation. What I need to do is to roll out of this boiling pot like a copper pea, and roll it out beautifully, rolling it so that the Japanese will break a few teeth."

To lead the troops across the Yangtze River in one go, relying solely on two legs and a few wheels is not enough.

We must have stronger hard assault capabilities and more ferocious burst firepower.

With a thought, Lin Feng displayed the system interface before his eyes.

Current exchange points: 5129

"It looks like a lot, but it'll only take a blink of an eye to spend it all."

First, exclude those heavy towed artillery pieces.

During the retreat, although he had a system space, he couldn't just follow the artillery. Therefore, he could wait until he reached a stable place to buy heavy artillery and the like.

"What I need is mobility, hit-and-run, artillery that can charge alongside tanks."

He wrote the words "rocket launcher" on the paper.

"Although the accuracy is a bit lacking, in a retreat battle, a volley of fire at the dense formation of pursuing Japanese soldiers would have an absolutely devastating effect."

Lin Feng calculated on paper: "120 points per rocket launcher, 12 launchers, forming a rocket artillery company. Estimated consumption: 1440 points."

Next came the qualitative change in armored forces.

He drew a sketch of a tank on a piece of paper and labeled it: "[Type II C]".

"Exchange for 16 Panzer II Ausf. C light tanks as the base. Price: 150 per tank, estimated cost: 2400 points."

Lin Feng drew an arrow next to the code name of 12 of the vehicles, pointing to the [II 150mm "Bison" self-propelled heavy infantry gun].

"The upgrade cost is 250 merit points per vehicle, so 12 vehicles would cost 3000 merit points."

This thing, mounted on the chassis of a Panzer II tank, carried a 150mm sIG 33 heavy infantry gun.

Although its design looks a bit top-heavy, like a mobile coffin, and its range is only 4.7 kilometers.

But it is a self-propelled artillery piece; it can move off-road with tanks and stop to fire at any time.

A single 150mm high-explosive shell could instantly reduce the Japanese pillboxes and machine gun emplacements to dust.

"The remaining 4 Panzer IIs..." Lin Feng paused, then wrote down "[Panzer III Ausf. L Medium Tank]".

"Upgraded to Type III L, serving as the spearhead of the armored company. With 50mm of frontal armor plus 20mm of additional armor, it was a wall of lament on the Great Xia battlefield of this era."

"The upgrade cost is 500 merit points per vehicle, so 4 vehicles would cost 2000 merit points."

"Add six more 38t tanks, and the framework of the armored battalion will be complete."

Lin Feng looked at the pattern on the paper and nodded in satisfaction.

Four Panzer III Ausf. L tanks formed the vanguard and tore open a breach.

The 38t light tanks followed closely behind, expanding the gains.

Twelve Bison self-propelled guns provided accompanying fire support, ready to take down the Japanese invaders at any time.

In addition, the 222/234 armored vehicles were responsible for reconnaissance and flank cover.

"The Japanese soldiers these days have very weak anti-tank firepower. As long as it's on a plain, one or two lines of defense simply can't stop this torrent of steel."

Finally, he wrote down on a piece of paper a plan to replenish mortars, heavy machine guns, 38t light tanks, armored vehicles, artillery, and ammunition.

"In summary..."

After some writing and calculations, Lin Feng concluded: "I should have about 800 exchange points left for emergencies. I need to spend another 6,000 merit points, leaving me with over 9,000. Perfect!"

He also has a lot of gold and foreign exchange banknotes in the system space for emergencies. If things get really desperate on the battlefield, he can just massacre a regiment of troops on the spot.

As for supplies?

Lin Feng glanced at the system space.

The mountains of canned meat, flour, and clothing there were enough for him to expand his army to 30,000 and feed them for another six months.

This is the sense of security that "hamster syndrome" brings.

-----

Over the next two days, Lin Feng began to execute the plan to rapidly expand his army step by step.

Under the cover of continuous wind and rain and the darkness of night, he completed the exchange and upgrade in batches at the camp.

A batch of bizarrely shaped yet violently aesthetically pleasing "Bison" self-propelled artillery pieces have quietly entered service.

The armored battalion was fully equipped and manned again, consisting of 12 38t light tanks, 12 Bison self-propelled guns, 14 armored vehicles, 3 Panzer IIIs, and 1 Tiger.

The other units are also undergoing intensive reorganization.

Time passed by in the midst of intense preparations.

until--

11 month 5 day.
