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

Qingcheng Port, the headquarters of the 33rd Army Corps.

Lin Feng put down the phone, his brows furrowing slightly.

Standing before the enormous sand table, gazing at the flag representing Weifang City, he fell into deep thought.

Urban warfare has always been a meat grinder.

The reason why we were able to take over Qingcheng Port so easily before.

The strategy relied on taking advantage of the Japanese troops' insufficient strength, first using the tactic of besieging the city and attacking the reinforcements to lure out the main force of the defending troops and eliminate them, and then using armored forces to launch a surprise attack on the undefended city.

But things are different now.

The Japanese soldiers had already realized what was happening.

They deployed a large number of troops, relying on sturdy buildings and intricate streets, determined to fight a street battle.

That means it will inevitably need to be worked out little by little.

Lin Feng knew very well that at this time, although the Japanese army had suffered setbacks in Jiaodong and the Fifth Division had been completely annihilated.

But they remain a modern army with high morale and an extremely ruthless fighting style.

It's unrealistic to expect that annihilating the entire Fifth Division would terrify the remaining Japanese troops and make them flee at the mere sight of them.

If the other side holds the city and engages in street fighting, then there's definitely a chance for a fight.

Especially the commander of the 114th Division, Shigeharu Suematsu.

After Zhang Wenzhong's report, Lin Feng confirmed that this was an extremely difficult person to deal with.

The other party is also learning and making progress.

Simple Molotov cocktails, wall-penetrating roofs, sniper rifles and cannons...

These were originally Lin Feng's tactics for dealing with the Japanese, but now the enemy has learned them and is using them against the Great Xia army.

"Want to play street fighting with me?"

Lin Feng sneered:

"Let's see whose methods are tougher."

He turned to look at the staff officer beside him:

"Pass on my orders."

A combat engineer battalion reinforced with explosives capabilities was immediately dispatched to reinforce the 107th Division.

Remember to equip them with plenty of flamethrowers. Don't the Japanese like to hide in buildings and snipe?

"Then just burn them to ashes."

Then, Lin Feng issued a second instruction:

"A regiment was transferred from the newly formed 16th Division to provide reinforcements."

They had all participated in the street fighting in Qingcheng Port and went there to directly share their experience in street fighting.

Tell Zhang Wenzhong to proceed steadily and not to be impatient.

Use explosives and flamethrowers to clear the way.

Move those 150mm Bison self-propelled heavy infantry guns from the 1st Honor Brigade into the city.

When you encounter a tough enemy strongpoint, don't sacrifice lives.

Use 150mm heavy artillery to demolish the building directly. We absolutely cannot waste manpower on futile efforts.

The staff officer quickly wrote down the order.

"And there's the logistics line."

Lin Feng pointed to the highway and railway connecting Qingcheng Port and the front line on the sand table:

"Some armored vehicles and light tanks were drawn from the 1st Honor Brigade to form patrol teams."

Patrol the logistics routes 24 hours a day without interruption.

The unimpeded transport of ammunition and fuel to the front lines must be guaranteed.

After arranging the battle situation at the front, Lin Feng waved his hand, signaling his staff to issue orders.

He then sat back down behind his large desk and rubbed his temples.

While the fighting is raging on the front lines, the construction work in the rear must also be accelerated.

Lin Feng closed his eyes, and with a thought, opened the system interface.

On the newly unlocked [Industry] exchange page, he quickly scrolled through the dazzling array of goods using his mind.

Soon, his gaze settled on an icon that was radiating a golden light.

[White Eagle 44 Edition Complete Penicillin Production Line]

[Price: 10 Exchange Points + 1 Merit Points]

[With just normal maintenance and the consumption of appropriate amounts of acid and nutrient solutions such as corn extract, deep fermentation can be carried out continuously to extract high-purity penicillin powder.]

[Includes: a complete set of physical equipment including a 7500 gallon large-scale deep liquid fermentation tank unit, a high-speed centrifuge, a vacuum freeze dryer, and an aseptic automatic filling machine.]

[Core technologies: High-yield mutant Penicillium strain (NRRL-1951-B25), complete set of drawings and process flow manual for submerged liquid fermentation technology.]

[Estimated annual production: 10 billion units of penicillin]

Looking at this long list of introductions, Lin Feng's heart couldn't help but beat a little faster.

This thing is practically a money printing machine!

The system covers everything: physical equipment, high-yield strains, and a complete set of technical drawings.

Lin Feng quickly did some mental calculations.

He recalled that in the original timeline, when White Eagle first began mass production of penicillin in 1943, the total annual output across the country was only a little over 10 billion units.

At that time, the standard dose of penicillin was 100,000 units.

The White Eagle (US) charges its European allies as much as $200 per dose.

In this era, the Dao Le was a hard currency directly linked to gold.

Thirty-five dollars can be exchanged for one ounce of gold.

Two hundred dollars is equivalent to more than five small gold bars.

Calculate based on the projected annual output given by the system.

1 billion units ÷ 10 units = 10 doses per year.

1 doses × 200 dollars = 200 million dollars.

Converted to modern silver dollars, that's an annual output value of five million silver dollars!

Of course, Lin Feng was also aware that the cost of this production line was not low.

One hundred thousand exchange points, according to the system's ratio, is equivalent to five million silver dollars.

This huge sum of money is enough for him to build up five more fully-equipped German-trained divisions.

Or it could provide enough for an infantry division to eat, drink, relieve itself, and fight for a year and a half.

If production goes smoothly, the investment can be recouped in just one year.

But that's just an ideal situation.

This is a complete production line that represents the highest level of biopharmaceutical technology in this era.

For it to operate smoothly, the number of skilled technicians and senior engineers required is definitely not small.

What he lacks most right now is this kind of high-end talent.

"If we don't have enough talent, we can train them gradually, or we can poach them."

Lin Feng gritted his teeth, a resolute glint in his eyes:

"But in 38 years, they were able to build a complete penicillin production line for the White Eagles, just like in 44."

This is absolutely a game-changer!

The penicillin produced can significantly increase the survival rate of wounded soldiers when an average of 10,000 units are produced.

An annual production of 10,000 doses is enough to save the lives of 100,000 wounded soldiers.

In this era of scarce medical resources and extremely high mortality rates from wound infections.

These antibiotics represent a large number of battle-hardened veterans who have survived countless battles.

At that time, it will not only be able to prioritize supplying its own troops, but also greatly reduce the casualty rate.

They could also sell any excess production on the black market or through trading companies to make money.

"If there is insufficient production capacity at that time, we can simply raise the price."

Lin Feng sneered, revealing his ugly face:

"At worst, we'll sell it for four hundred dollars a dose, plus ten small yellow croakers! Those foreigners would sell their pots and pans to buy it to save their lives."

More importantly, there is such an advanced production line.

It also greatly promoted the progress of biomedical science in Daxia.

This is a truly beneficial act for the country and its people.

"Let's do it!"

Lin Feng slammed his hand on the table.

He has just raided the homes of so many traitors and confiscated the Japanese bank vaults.

The funds are plentiful.

Without hesitation, he clicked the "Redeem" button with his mind.

[Ding! 10 exchange points and 1 merit points deducted.]

[Successfully redeemed a complete set of 44 White Eagle penicillin production lines.]

[The relevant equipment and drawings have been stored in the system space. Please select a suitable location to materialize them.]

Hearing the system notification in his mind, Lin Feng let out a long sigh of relief.

With this money-printing machine, his future plans to rapidly expand his army would have a continuous source of funding.

The next step is to find a safe place to build the factory.

Then we need to figure out a way to get a group of skilled technicians.
