Spy satellites are a crucial part of the Red Alarm system.

In the game, this is lit up in full screen and you can see anywhere through the radar.

At present, the radar of the Shuguang Army with a 50-kilometer radius is obviously unable to keep up with the situation, and at least the movements of the zombies in the distance cannot be detected.

If there are spy satellites here, then combat will undoubtedly be much more convenient.

Although this guy's cost reached 2 million gold, Ye Fan still clicked on the production without hesitation.

2 million gold is spent, and spy satellites are beginning to be included in production options.

"It will take 2 million yuan to build a spy satellite, and it will take fourteen days. Please wait patiently!"

Although the time has been a little longer, Ye Fan thinks it is worth it.

What he is not sure about is how large the coverage of this spy satellite can reach.

The game can be full-screen because the game is only so big. When it comes to the real world, it is obviously impossible to cover the entire planet.

In Ye Fan's opinion, it is very difficult to cover more than one city.

If it can really cover a city, it will be of great help to Ye Fan in the future.

After clicking on the spy satellite, what Ye Fan had to do next was to fight the violent soldiers.

Before Ye Fan could prepare for the violent soldiers, Nana issued a prompt.

"Sir, the Army Operations Laboratory engineer has completed a new soldier unlocking, which has appeared on your soldier page, please check it out."

"Oh! Could it be that the giant cannon has been completed? It shouldn't be, the giant cannon should be on the mechanical vehicle page."

Ye Fan opened the soldier page and saw that there was indeed a new soldier.

25mm chain machine gun: cost 4,000 gold.

Chain machine guns are transformed based on machine guns of armored trains. The machine guns are connected to machine guns by motors, and will not stop firing because of a certain shell.

The maximum range of the machine gun is 4,000 meters, the maximum range of the air is 2,000 meters, and the amount of ammunition is 5,000 rounds in the star-free state, which requires two-person operation.

Note: It cannot be moved after installation, and can be directly placed in the sentry building.

This thing is much taller than a machine gun just by looking at the pictures.

This is a metal baffle that is more than one person tall, and is equipped with machine cannons, motors, ammunition boxes and other things.

Without drag wheels and tools, you cannot be carried forward by the car.

Although it cannot be carried forward by the vehicle, the appearance of this weapon greatly compensated for the insufficient firepower of Ye Fan defending the city.

With the increasing evolution of zombies, ordinary guns are becoming less and less lethal to advanced zombies.

For example, King Kong zombies and heavy machine guns cannot pose a great threat to them.

The emergence of machine guns is just the time. Judging from the combat situation of armored trains, machine guns can effectively kill second-level mutant zombies.

Seeing the appearance of the machine gun, Ye Fan immediately ordered to continue to pull up Buman in the outer city of Shuguang City, and he wanted to build a new batch of ten-meter artillery towers!

Last time, Ye Fan had built a batch of ten-meter artillery towers, but the machine guns were installed on the sentry towers, and the number of sentry towers was small. This time, he had money in his hand, so he wanted to set up a batch of machine artillery!

The cost of machine guns is 4,000, and the cost of 1,800 for the ten-meter whistle tower. If you remove the heavy machine guns on them and replace them with machine guns, it will be 5,000 per person.

Create a hundred!

Just 500,000 gold, Ye Fan is not short of money!

He wants to arrange a circle of the outer city, inner city, core area, and the entire Shuguang City to lay a ten-meter-long sentry tower.

The zombie is coming, so let him taste the bullet storm in Dawn City!

After receiving Ye Fan's order, the engineer troops immediately dispatched and began to pull up Buman from the outer city wall to block people's sight.

The people of Shuguang City who have already experienced this are no wonder. In their opinion, the construction speed of the Shuguang Army is really world-class. Under the conditions of ice and snow, a circle of whistles can be built in a few days.

The engineer troops are indeed professional.

After spending 500,000 gold, Ye Fan has already spent 5 million gold.

One million repairs to the factory and one million air force combat laboratories to the Air Force.

There are two million spy satellites and five hundred thousand machine guns.

There are still 13 million gold in hand.

Currently, Ye Fan’s Shuguang Army has more than 6,200 Red Alert Units.

He built twelve barracks, which can accommodate up to 6,600 people.

Since the War Eagle and War Bear joined, Ye Fan no longer allowed military dogs to occupy the formal organization.

These three mutant beasts do not occupy the organization because they do not need to rest in the barracks.

It is too late for Ye Fan to continue to increase his barracks, because the production sequence of the buildings has been occupied by the Air Force Operations Laboratory.

So normally, his continued increase in troops can only increase the number of troops to 6,600.

However, it is obviously not enough for these troops to cope with the upcoming war. According to Ye Fan's estimate, the scale of the zombies this time should be around three million, which is ten times the previous one.

Therefore, the troops must be expanded, but it is impossible to allow the soldiers to camp in the open air. After all, it is winter now and there is no way to live outside.

Just when Ye Fan was having a headache, Nana gave Ye Fan a tip.

"Sir, the maximum force you can expand at present should be 13,200 people. Among the twelve barracks, the soldiers have two people and one bed, taking turns to rest, which is OK in a short period of time."

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

The soldiers had to take turns to stand guard, and it was nothing for the two of them to live in the same bed for the time being.

The Red Alert Soldier is full of energy, and sleeping for four to six hours a day is enough.

Even if there is a female soldier who is inconvenient to live in the military camp, Ye Fan can feel aggrieved and let the female soldier live in his official residence for the time being.

Ye Fan still has this kind of mind.

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

With confidence in his heart, Ye Fan began to fight violently.

Currently, his troops have a regiment of 4,000 people, and now they belong to one and a half regiments.

There are more than 500 air force troops and more than 5,700 army troops.

Ye Fan of the Air Force has not moved for the time being. He plans to wait until the Air Force Operations Laboratory comes out before researching.

The most important thing at the moment is to create troops to defend the city.

Relying on machine guns alone is definitely not enough. Machine guns are used to fight advanced zombies and large mutant beasts. The massive amount of ordinary zombies still have to rely on ordinary soldiers to solve the problem.

According to the organization of a group of 4,000 people, Ye Fan began a new production.

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

Twelve thousand people!

Ye Fan calculated the average value of a regiment.

The minimum mobilization of one hundred troops is 200 army soldiers.

Some advanced troops often cost thousands. If a regiment does not count vehicle types, the cost of a soldier alone is about one million.

If you add various vehicles, it will be at least 1.5 million.

If all the full sets are fully equipped, it will cost two million.

This time Ye Fan expanded his troops, he simply expanded his troops to a full-scale state.

Here, let Nana calculate the military data for herself, and Ye Fan started to spend money here.

In addition to the lack of production of helicopters and tanks, Ye Fan also focused on manufacturing artillery.

There were only twenty cannons, but this time it expanded to fifty!

The 107 rocket launcher was originally only thirty, but this time it expanded to 100!

Mortars have also been expanded to one hundred!

In this way, Ye Fan formed a completed artillery system here.

There are cannons at long range, rocket launchers at medium range, and mortars at short range.

If the giant cannon is developed again, then within a few dozen kilometers of Shuguang City, all of them are within the cannon strike range.

Although there are enough zombies, see if you can withstand the bombardment of the cannon group!

Three million and five million yuan were spent, and the army troops were directly promoted to the full state of three regiments!

Twelve thousand people!

With the current city guards, such as the soldiers, artillery and guard companies in the post, Ye Fan's army has reached 12,500!

With the air force, it has reached 13,000!

He can still produce about 200 soldiers, but Ye Fan did not continue. He wanted to leave some space for the new soldiers after the Air Force combat laboratory came out.

But if the soldiers don’t make it, there will be no place to live, which is a bit embarrassing.
To be continued...
