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

As night fell, the temporary repair shop outside Jiangyin City was brightly lit.

Today, all the vehicles of the armored battalion are parked here for maintenance and repair.

Sun Ziqiang and his maintenance team were working hard, with sparks flying from the welding and the sounds of hammering echoing everywhere.

Sun Ziqiang has now been promoted and appointed by Lin Feng as the colonel director of the Provisional 8th Army's Ordnance Repair Shop.

Without disturbing the other party, Lin Feng went alone to the open space where heavy equipment was parked.

With a thought, the system space opened.

"Buzz—"

The highly decorated Tiger tank, number 231, along with several damaged 38(t) and 222 armored vehicles, appeared out of nowhere in the open field.

Although the Tiger tank was imposing, after a series of fierce battles, its body was covered with bullet holes, and its camouflage paint was scratched off, making it look somewhat weathered.

"Old buddy, you've worked hard."

Lin Feng patted the heavy armor plate and then opened the system interface.

Current Merit Points: 17316

Current permission level: Level IV (11002/100000)

Looking at this huge sum of money, Lin Feng decided to upgrade the quality of the defense for the upcoming battle.

His gaze fell curiously on the Tiger tank.

Can the Tiger tank be upgraded?

With the thought locked on, the system presented upgrade options:

[Upgraded to - Tiger II Ausf. VI B Heavy Tank]

[Merit Points Required: 1000]

[Armor: 88mm KwK 43 L/71 tank gun, 150mm frontal armor (sharply sloped)]

[Note: This is the pinnacle of mass-produced heavy tanks from World War II, an extreme product of excessive water and flour, and excessive flour and water. In this context, it is synonymous with invincibility. Compared to it, the Japanese tanks are not even toys.]

Sure enough, after obtaining Level IV clearance, the Tiger can evolve into the Tiger King.

Lin Feng swallowed.

Tiger King, that's the true king of land warfare.

But... it's too heavy.

Lin Feng shook his head.

With a weight of 56 tons, the Tiger tank already posed some mobility challenges on the battlefields of the Great Xia Dynasty in that era, requiring extreme caution even when crossing bridges.

The Tiger King weighs a staggering 70 tons.

Moreover, the long 88mm gun had far more firepower than the short 88mm gun of the Tiger.

The Japanese didn't have any IS-2 heavy tanks to fight, so using a Long March 88 to shoot down a small tank was like using a cannon to kill a mosquito.

"Upgrading it to Tiger King would truly make it an absolute force in terms of defense and firepower, but I would also have to become its caretaker. I would have to stay with this super-heavy tank all the time, ready to take it across rivers and bridges using the system space at any time, which would be too inconvenient."

Pass for now.

Keep reading.

[Upgraded to - 380mm "Sturmtiger" self-propelled mortar]

[Merit Points Required: 500]

[Equipment: 380mm rocket mortar]

[Note: One shot, one kill; a surefire way to crush any challenger. One shot can obliterate half a block. This is the ultimate answer for urban warfare and building demolition.]

"This is indeed very necessary."

Lin Feng stroked his chin.

The 380mm rocket was absolutely devastating.

If we launch a counterattack in the future and encounter the Japanese Tiger Head Fortress or other strong city defenses, this thing will definitely be a demolition artifact.

However, we are currently in a strategic defensive phase, so it's not necessary for the time being.

Upgraded to – "Elephant" Heavy Tank Destroyer

[Merit Points Required: 500]

[Note: Although its mobility is terrible, in defensive warfare it's a lifesaver. Even if the Japanese brought their 100mm naval guns ashore, they couldn't penetrate its surface.]

Just looking at these options made Lin Feng drool with envy.

Each upgrade path is very strong, but they all seem to be somewhat out of place at present.

"Forget it, let's leave the Tiger Pistol as it is for now; it's good enough anyway."

Lin Feng turned his gaze to the 38(t) light tank next to him.

This thing only weighs 10 tons; after all, it's a light tank, thin-skinned and large-capacity.

The Japanese will definitely use heavy artillery next, and they will also prepare a lot of anti-tank guns. After being hurt in several armored battles, they may even temporarily import anti-tank rifles.

The living environment of 38(t) is worrying.

"Upgrade."

The interface refreshed.

[38(t) Jagdpanzer 38 (T) tank destroyer], [75mm Marder III self-propelled anti-tank gun], [150mm Growl self-propelled howitzer], [20mm 38(t) self-propelled anti-aircraft gun]...

Lin Feng chose the Hunter without hesitation.

[Upgraded to - 38(t) Jagdpanzer Tank Destroyer]

[Merit Points Required: 400]

[Armor: 75mm PaK 39 L/48 anti-tank gun, 60mm steeply sloped frontal armor]

[Note: A prime example of a small vehicle carrying a large cannon: low-profile, concealed, and with fierce firepower. Although its visibility was somewhat poor, it was a nightmare for the Japanese in ambush tactics.]

"400 points? That's 100 points cheaper than upgrading from II to III L?"

Lin Feng was secretly delighted.

Perhaps it's because the 38(t) light tank and the Jagdpanzer share the same chassis.

With a wave of his hand, he upgraded all eight 38(t) vehicles to Jagdpanzer.

A flash of light, and the towering turret disappeared, replaced by low, sloped armor and a long 75mm cannon.

The 75mm gun has a stronger anti-tank capability and is more powerful when firing high-explosive shells than the original 37mm gun. The downside is that without a turret, it is somewhat inconvenient to maneuver.

As for the Type 222 armored vehicle, it is currently sufficient as a supplement to air defense firepower and a light, rapid reconnaissance unit. The only drawback is that its numbers are still a bit too few.

"Money, money, money, still not enough."

Lin Feng sighed and turned to go to the air defense battalion's location.

-----

Inside the air defense battalion's garrison, rows of anti-aircraft guns stand proudly.

Lin Feng had already converted the 5 silver dollars that Commander Liao had given him into 1000 exchange points.

Considering the high probability of facing relentless bombing raids by Japanese army and navy aircraft, Lin Feng did not try to save money.

"System, purchase 10 Flak 30 20mm anti-aircraft gun squads."

The 900 redemption points are gone.

What followed was a frenzy of upgrades.

"Upgrade all to Flak 38 quadruple 20mm anti-aircraft guns."

Nearly 4000 merit points are gone.

But when the single-barreled system is converted to a four-barreled system, the firepower density instantly quadruples.

But this is not enough.

Lin Feng looked at one of the quadruple anti-aircraft guns and his mind stirred once more.

Upgraded to – "Whirlwind" self-propelled anti-aircraft gun

[Merit Points Required: 400]

[Armament: Panzer IV chassis, nonagonal open turret, 4 x 20mm Flak 38 anti-aircraft guns]

[Note: Tracked field anti-aircraft gun, the Panzer IV chassis gives it excellent survivability, and its quadruple autocannon is enough to tear apart any low-flying target.]

"Awesome!"

1600 merit points spent.

Looking at the four "Whirlwind" anti-aircraft vehicles that appeared in front of him, Lin Feng couldn't help but admire them.

It was directly converted into the chassis of the Panzer IV tank.

This will allow for field air defense, which is far more advanced than his previous "battlefield modification" that involved welding a single-barreled anti-aircraft gun into the back of a truck.

The frontal armor of the Panzer IV chassis was 50 mm thick, which the Japanese 37 mm cannons couldn't penetrate at long range.

Although the thin turret was a weakness, Lin Feng didn't expect to use the Whirlwind for armored warfare. Using it for anti-aircraft defense and occasionally laying it flat to straf Japanese infantry would be a massacre.

After these maneuvers, the air defense battalion's strength increased dramatically, to the point that it could almost be called an anti-aircraft artillery regiment.

88mm重高射炮2门，37mm中型高射炮4门，四联装20mm高射炮14门，旋风防空车4辆，20mm单管防空卡车6辆。

The barrage of comments is at maximum density!

"With so many anti-aircraft guns, it should be enough to hold the Huashan position and the skies over the county town."
