The spy satellite is a crucial component of the Red Alert System.

In the game, it's all-screen lighting, allowing you to see any place via radar.

Currently, the radar with a fifty-kilometer radius of the Dawn Army is clearly lagging behind the situation, at least unable to detect the movements of distant zombie hordes.

If there were a spy satellite, combat would undoubtedly be much more convenient.

Although this thing costs 2 million gold, Ye Fan clicked to manufacture it without hesitation.

2 million gold spent, the spy satellite began to be listed in the production options.

"Confirmed to build a spy satellite, requires 2 million gold, takes fourteen days, please be patient, Commander!"

Even though it takes a little longer, Ye Fan believes it's worth it.

What he is unsure about is how large the coverage area of this spy satellite could be.

In the game, it's all-screen because the game world is only that big; in the real world, covering the entire planet is obviously impossible.

In Ye Fan's view, being able to cover above a city is a very difficult thing.

If it really can cover a city, it will also be greatly beneficial for Ye Fan's future.

After selecting the spy satellite, Ye Fan's next action is to rapidly recruit troops.

Before Ye Fan could prepare to rapidly recruit, Nana issued a notice.

"Commander, the engineers at the Army Combat Laboratory have completed unlocking a new soldier type, which has appeared on your soldier page, please have a look."

"Oh! Could it be that the Giant Cannon is completed? It shouldn't be, it should be on the mechanical vehicle page."

Ye Fan opened the soldier page and indeed found a new soldier type.

25mm Chain Gun: Cost 4,000 gold.

The chain gun is modified from the armored train's gun, connected by a motor to the gun, and will not stop shooting due to a misfiring shell.

Maximum range of 4,000 meters, maximum anti-air range of 2,000 meters, with an ammunition capacity of 5,000 rounds in a no-star state, requires two operators.

Note: Once installed, it cannot be moved and can be directly placed on a watchtower.

Just looking at the picture of this thing, it's much grander than a heavy machine gun.

It is equipped with a metal shield over a person high, combined with a gun, motor, ammunition box, and other supporting equipment.

No towing wheels or tools, cannot be advanced by vehicle.

Although it cannot be advanced by vehicle, the appearance of this weapon greatly compensates for Ye Fan's lack of city defense firepower.

With zombies continuously evolving, ordinary firearms have less and less damage against advanced zombies.

For example, against King Kong Zombies, even heavy machine guns cannot pose a major threat.

The appearance of the chain gun came just in time; judging by the combat situation of armored trains, the chain gun can effectively inflict damage on Level 2 Mutated Zombies.

Seeing the chain gun's appearance, Ye Fan immediately ordered to enclose the area in the outer city district of Dawn City, he wanted to construct a batch of ten-meter watchtowers!

The last time Ye Fan had already built a batch of ten-meter watchtowers, but the ones on the watchtowers were machine guns, and the number of watchtowers was very few as well. Now that he has the money, he wants to equip a batch of chain guns!

The chain gun costs 4,000, and the ten-meter watchtower costs 1,800; replacing the heavy machine gun above with a chain gun would make it 5,000 each.

Build one hundred!

Just half a million gold, Ye Fan is not short of money!

He wants to set up a circle of ten-meter watchtowers throughout the outer city district, inner city district, and core district of Dawn City.

If the zombies come, let them taste the bullet storm of Dawn City!

Upon receiving Ye Fan's order, the Engineer troops immediately moved out, starting to erect barricades on the outer city district walls to block people's view.

The citizens of Dawn City who have experienced this situation were not surprised at all. In their opinion, the Dawn Army's construction speed is world-class. In just a few days, even in freezing conditions, a circle of watchtowers could be built.

The Engineer troops are indeed professional.

With half a million gold spent, Ye Fan had already spent a total of five million gold.

Repair factory 1 million, Air Force Combat Laboratory 1.5 million.

Spy satellite 2 million, chain guns 0.5 million.

He still has 13 million gold in hand.

Currently, Ye Fan's Dawn Army has over 6,200 Red Alert Units.

He has constructed twelve barracks, accommodating at most 6,600 people.

Since War Hawks and War Bears joined, Ye Fan also no longer lets war dogs take up formal slots.

These three mutant beasts do not take slots because they don't need to rest in barracks.

At present, it is too late for Ye Fan to continue increasing barracks, as the production sequence of the buildings is occupied by the Air Force Combat Laboratory.

So normally, he can only increase soldiers to let the barracks accommodate 6,600 people.

But these troops are obviously inadequate to cope with the impending battle. This time, according to Ye Fan's estimates, the scale of the zombies should be around 3 million, about ten times the last time.

So the troops must be expanded, but it's also impossible to make soldiers camp out, after all, it is winter and staying outside is impossible.

While Ye Fan was getting a bit worried, Nana gave Ye Fan a tip.

"Commander, the maximum number of troops you can currently expand to should be 13,200 people. Within the twelve barracks, having soldiers share beds, taking turns resting, is doable in the short term."

Ye Fan's eyes instantly lit up, good idea!

The soldiers are already taking turns on duty, temporarily sharing a bed is not a big deal.

Red Alert Soldiers are energetic, needing only four to six hours of sleep a day.

Even if it is inconvenient for female soldiers to stay in the barracks, Ye Fan can temporarily accommodate them in his residence.

Ye Fan still has this kind of magnanimity and tolerance.

At worst, let Company Commander Shen and the others move out.

With confidence in his heart, Ye Fan began to mass-produce soldiers.

Currently, his troop organization consists of one regiment with four thousand people, now it's equivalent to one and a half regiments.

The air force consists of over 500 people, and the army has more than 5700 people.

Ye Fan hasn't touched the air force yet; he plans to wait until the Air Force Combat Laboratory is out before studying it.

Right now, the most important thing is to create forces to defend the city.

Relying solely on machine guns is definitely not enough; machine guns are for fighting advanced zombies and large mutant beasts. As for the masses of regular zombies, they still need to be dealt with by regular soldiers.

According to the organization of a regiment with four thousand people, Ye Fan started new production.

He wants to expand the troops to three regiments at once!

Twelve thousand people!

Ye Fan calculated the average cost of producing one regiment.

The cheapest is the conscript at one hundred, army soldier at two hundred.

Some advanced soldier types cost over a thousand; not counting vehicle classes, the cost of soldiers alone is around one million.

If all kinds of vehicles are added, it's at least 1.5 million.

If fully equipped and fully staffed, it would take 2 million.

This time, when Ye Fan expanded his troops, he simply expanded them all to full staffing.

Nana calculated the soldier data for him, and Ye Fan started spending money heavily.

Apart from not producing helicopters and tanks, Ye Fan focused on manufacturing artillery.

Originally there were only twenty howitzers, but this time they expanded to fifty!

The D-77 style rocket launchers were originally only thirty, now expanded to one hundred!

Mortars also expanded to one hundred!

In this way, Ye Fan formed a complete artillery system.

With long-range howitzers, mid-range rocket launchers, and close-range mortars.

If the Giant Cannon is developed, then within the dozens of kilometers of Dawn City, everything is within the artillery's strike range.

Zombies are numerous enough, let's see if they can withstand the bombardment of the artillery group!

3.5 million of money was spent, directly raising the army to the status of three full regiments!

Twelve thousand people!

With the current city defense forces, like those soldiers in the watchtowers, artillery, and the Guard Company, Ye Fan's army reached twelve thousand five hundred people!

Adding the air force, it reached thirteen thousand!

About two hundred more soldiers can be produced, but Ye Fan didn't continue. He wants to leave some space for new soldier types once the Air Force Combat Laboratory is out.

Don't let the soldiers be produced and have nowhere to stay, that would be quite awkward.

Even as it is now, two soldiers have to squeeze into one bed; it's still Ye Fan, as the commander, voluntarily taking responsibility, willing to accommodate female soldiers.

This 3.5 million money spent leaves Ye Fan with only 9.5 million in hand.

"This is simply spending money like water!"

Ye Fan couldn't help but sigh in his heart.

Although a lot of money is spent, Ye Fan feels very satisfied.

Starting with the construction of repair factories, 8 million gold was spent consecutively.

But what was exchanged was rapid progress in strength.

The number of troops directly doubled, with a total of thirteen thousand people.

Of course, these thirteen thousand people aren't gathered immediately; production also requires a process.

He has twelve barracks, and the speed of spawning soldiers is very fast.

Now each barracks has already begun to deploy soldiers; in four or five days, the troops will be fully assembled.

Don't just look at the number only doubling, the actual combat strength of the troops absolutely increased by four or five times at least!

Take nothing else but that row of dozens of howitzers; months ago, one full salvo could have turned the once Dawn City to ruins.

This is the power brought by technology, definitely not something that a numbers advantage can match.

Of course, the numbers advantage is also useful, at least against zombies, numbers can still play a big role.

After repeatedly calculating, Ye Fan confirmed that the current production can probably handle the situation, and only then did he feel slightly relieved.

Next, he just needs to patiently wait for the troops to appear, and then wait for the zombies to come knocking.

These things sound simple, but Ye Fan was busy all day.

When he finally completed all unit production, the time had already reached the evening of the twenty-ninth.

After checking the condition of the armored trains, the trains are still charging back and forth in Huacheng and Pinggang Town.

The car body has been covered in thick blood plasma but shows no sign of giving up.

It's just that the consumption of bullets is very large, estimated to last at most one more day, by the thirtieth it must be withdrawn.

"Pretty much done, it's time to go out and take a look, prepare to enjoy New Year properly!"
