Spy satellites are a vital part of the Red Alert system.

In the game, it's full-screen lit and can be seen anywhere through the radar.

At present, the radar within a radius of 50 kilometers of the Dawning Army is obviously unable to keep up with the situation, at least the movement of the zombie group in the distance cannot be detected.

If there are spy satellites, then there is no doubt that it is much more convenient to fight.

Although the cost of this guy reached 2 million gold, Ye Fan still clicked on it without hesitation.

2 million gold was spent, and spy satellites began to be included in the production option.

"It is determined that the construction of a spy satellite will require 2 million gold, and it will take fourteen days, please be patient!"

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

What he wasn't sure was how much coverage this spy satellite would be able to reach.

The game can be full-screen, that's because the game is only so big, and in the real world, it's obviously impossible to cover the entire planet.

In Ye Fan's view, it is not easy 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, the next thing Ye Fan has to do is a rioter.

Before Ye Fan could prepare for the riot, Nana sent out a prompt.

"Sir, the Engineer of the Army Operations Lab has completed a new class unlock, and it has appeared on your Soldier page, so keep an eye out for it. ”

"Oh, is the cannon finished? No, the cannon should be on the Mechanical Vehicles page. ”

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

25mm chain cannon: cost 4000 gold.

The chain cannon is based on the machine gun of the armored train, and the machine gun uses a motor to connect the machine gun, and will not stop firing because of a certain shell.

The maximum firing range of the machine gun is 4,000 meters, the maximum firing range of the anti-air is 2,000 meters, and the ammunition volume is 5,000 rounds in the starless state, which requires two people to operate.

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

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

This is a piece of equipment with a metal baffle more than one person high, and a cannon, motor, ammo box, and other things.

Without towing wheels and tools, it cannot be carried forward by a vehicle.

Although it could not be carried forward by a vehicle, the appearance of this weapon largely made up for the lack of firepower of Ye Fan's defense of the city.

As zombies evolve, ordinary firearms are becoming less and less lethal to high-level zombies.

For example, King Kong Zombies, heavy machine guns can't pose a big threat to them.

And the appearance of the machine gun came at the right time, judging from the combat situation of the armored train, the machine gun can effectively kill the second-level mutant zombies.

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

Last time, Ye Fan had already built a batch of ten-meter turrets, but machine guns were erected on the sentry towers, and the number of sentry towers was also very small, this time he had money in his hands, and he wanted to erect a batch of machine guns!

The cost of the machine gun is 4,000, the cost of the ten-meter sentry tower is 1,800, and if you remove the heavy machine gun on it and replace it with a machine gun, it is 5,000 each.

Build a hundred!

It's only 500,000 gold, Ye Fan is not bad for money!

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

If the zombies are coming, let him taste the bullet storm in Dawning City!

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

The people of Dawning City, who have already had such an experience, are not surprised, in their opinion, the construction speed of the Dawning Army is really world-class, and in the case of ice and snow, a circle of sentry towers can be built in a few days.

The engineering unit deserves to be professional.

500,000 gold was spent, and Ye Fan had already spent 5 million gold.

One million repair factories and one and a half million combat laboratories for the Air Force.

2 million spy satellites and 500,000 machine guns.

He still has 13 million gold in his hand.

At present, Ye Fan's Dawn Army has more than 6,200 red police units.

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

Since War Eagle and War Bear joined, Ye Fan no longer let military dogs occupy the regular establishment.

All three of these mutants do not occupy the establishment, as they do not need to rest in the barracks.

At present, it is too late for Ye Fan to continue to increase the barracks, because the production sequence of the building has been occupied by the Air Force Combat Laboratory.

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

But these forces are obviously not enough to deal with the upcoming big war, and the scale of the zombies this time should be around three million according to Ye Fan's estimate, which is ten times that of the last time.

Therefore, the army must be expanded, but it is impossible for the soldiers to camp in the open air, after all, it is winter, and there is no way to live outside.

Just when Ye Fan had a headache, Nana gave Ye Fan a hint.

"Sir, the maximum force you can expand at present should be 13,200 people, and in the twelve barracks, the soldiers have two people in a bed and take turns to rest, which is okay for a short time. ”

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

The fighters were supposed to take turns to stand guard on duty, and it was nothing for two people to live in the same bed for the time being.

The Red Guard soldiers are full of energy, and four to six hours of sleep a day is enough.

Even if it is inconvenient for a female soldier to live in the barracks, Ye Fan can also be wronged and let the female soldier temporarily live in his official residence.

Ye Fan still has this bit of heart.

It's a big deal to let Company Commander Shen and them move out.

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

At present, his unit is composed of 4,000 men in a regiment, and now it belongs to one and a half regiments.

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

The Air Force Ye Fan did not move for the time being, and he planned to wait until the Air Force Operations Laboratory came out to study it.

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

It is definitely not enough to rely on machine guns alone, machine guns are used to fight high-level zombies and large mutant beasts, and the massive number of ordinary zombies still have to rely on ordinary soldiers to solve them.

According to the establishment of a regiment of 4,000 people, Ye Fan started a new production.

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

12,000 people!

Ye Fan calculated the average value of producing a regimental force.

The minimum mobilization is one hundred, and the army soldier is two hundred.

Some high-level troops are often in the thousands, and if a regiment does not count the vehicle class, the cost of a soldier alone is about one million.

If you add all kinds of vehicles, it is at least 1.5 million.

If the full crew is fully equipped, it will cost two million.

Ye Fan expanded his troops this time, and simply expanded his troops to a full state.

Here let Nana calculate the class data for herself, and here Ye Fan began to throw money.

In addition to the fact that helicopters and tanks were not produced, Ye Fan also focused on the manufacture of artillery.

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

The 107 rocket launcher originally had only thirty units, but this time it was expanded to a hundred!

The number of mortars has also been expanded to a hundred!

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

There are cannons at long range, rocket artillery at medium range, and mortars at close range.

If the giant cannon is developed again, then all within a few tens of kilometers of Dawn City will be within the strike range of the cannon.

Although there are enough zombies, let's see if we can withstand the bombardment of the cannon group!

The money of 3.5 million yuan was smashed out, and the army unit was directly promoted to the full strength of three regiments!

12,000 people!

Coupled with the current garrison troops, such as the soldiers, artillery and guard companies in those guard towers, etc., Ye Fan's army force reached 12,500 people!

With the addition of the Air Force, it reaches 13,000!

It can also produce about two hundred soldiers, but Ye Fan did not continue, he wants to leave a little space for the new troops after the Air Force combat laboratory comes out.

But if you don't want the soldiers to make it, it will be a little embarrassing to have no place to live.

Even now, if two soldiers are squeezed into a bed, it is still the case that Ye Fan, the commander, takes the initiative to take responsibility and is willing to accept female soldiers.

The 3.5 million gold was smashed out, and the money in Ye Fan's hand was only 9.5 million.

"It's a lot of money!"

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

Although the money was spent a lot, Ye Fan felt very happy.

Starting with the construction of the maintenance factory, eight million gold were spent in a row.

But in exchange for the strength has increased by leaps and bounds.

The number of troops was directly doubled, and the total number reached 13 thousand.

Of course, this 13,000 people will not be able to arrive immediately, and production also requires a process.

He had twelve barracks, and the speed of the rioters was fast.

Now the various barracks have already begun to send troops, and in four or five days, all the production troops will be able to arrive.

Don't look at the number of people who have only doubled, but the actual combat effectiveness of the troops has definitely increased by four or five times!

If nothing else, that row of dozens of cannons, placed a few months ago, could have turned the former Dawn City into ruins with a single salvo.

This is the power brought by technology, and it is definitely not comparable to the superiority in numbers.

Of course, the numerical advantage is also useful, at least when playing against zombies, the number of people can still play a big role.

After calculating repeatedly, Ye Fan determined that the current production was almost able to cope with the situation, so he was a little relieved.

Next, you need to wait patiently for the troops to appear, and then wait for the zombies to come to the door.

These things are easy to say, but Ye Fan has been busy all day.

By the time he had finally completed the production of all the units, the time had come to the evening of the twenty-ninth day of the lunar month.

After checking the situation of the armored train, the train was still rushing back and forth in Huacheng and Pinggang Town.

The body of the car was covered in thick plasma, but there was no sign of holding on.

It's just that the consumption of bullets is very large, and it is estimated that it can last at most one day, and it must be withdrawn by the Chinese New Year's Eve.

"It's almost, it's time to go out and have a look, and get ready for a good year!"
