Since the beginning of junior high school, Ye Fan has entered a busy state.

The newly built ten-meter sentry tower was placed by him one by one, first from the outer city.

Because construction takes time, the process is actually quite long.

Inside the bushman, where the watchtower was placed, the view of the people was obscured.

As long as the outer city is placed first, the inner city and the main city will be easy to do, where there are crack generators to cover it, and no one can probe the inside.

One hundred sentry towers were placed until the third day of the Lunar New Year.

On top of each watchtower, there is a 25mm machine gun.

Although the cost of a sentry tower with a machine gun is high, the high cost also has the advantage of high cost.

A weapon that can kill second-level mutant zombies, it is destined to become the main force defending the city in the future.

On the evening of the third year of junior high school, Ye Fan got the news that the zombie group was coming again.

The zombie took a diagonal line from Pinggang and went to the Harvest Reservoir, but in fact, the distance from Dawn City did not change at all.

And the weather has been getting better and better in the past two days, not only has the wind and snow stopped, but the temperature has also risen.

According to the speed of the zombie group day and night, tomorrow afternoon, that is, the fourth day of the Lunar New Year, the zombie group will arrive at the Dawn City.

"There is still one day to go, and the Air Force Operations Laboratory will not be completed until the sixth year of junior high school. ”

Ye Fan thought about it and interrogated Wang Shun and Luo Jiaxin in the system.

"When will the development of the giant cannon be completed?"

"Sir, it will take another half a month. ”

"Then if I add you Hero Engineers, can I shorten the time?"

Now there are still three vacancies in the second hero battalion, because the combat laboratory is under construction, so Ye Fan has no time to increase the hero battalion, so he has not used these three vacancies.

"Sir, the research and development of giant cannons has reached a limit speed, and some scientific research projects are not fast because of the number of people. ”

Hearing Wang Shun's answer, Ye Fan dispelled the idea of continuing to increase the number of engineers.

Although the current city defense seems to be very stable, Ye Fan knows that it is not that simple.

The zombies have evolved to a considerable height, and this siege is more than ten times more difficult than the last one.

If it is still the same as last time, the highest is the second-level King Kong zombie, not to mention three million, even ten million Ye Fan has the confidence to defend it.

But this time, there are more mutant birds, mutant beasts, and the large-scale evolution of zombies, and the difficulty is almost increased geometrically.

So everything that can be thought of here must come in handy as soon as possible.

The first is Lay.

Hearing the news of the arrival of the zombies, Ye Fan produced three minelaying vehicles again, and five minelaying vehicles are currently busy outside the city.

A minelaying vehicle can lay 900 mines, and the cost is 6,000 gold.

And the production of mines from the arsenal costs 5 gold for one.

Ye Fan didn't build too many minelaying vehicles, and after arranging the mines he carried, he bought them from the arsenal.

One car is 4,500 gold when you buy it once, and five cars are 22,500 gold.

And five vehicles are arranged once, and 4,500 mines are also arranged.

Ye Fan let the vehicles be arranged back and forth repeatedly, and 450,000 mines were arranged around the city!

This large-scale mine-laying operation cost 2.25 million gold!

At this time, within a radius of ten kilometers from the urban area of Dawning City, almost all of them were minefields!

There are not so many mines in the rear of the core area, as well as in the east and west urban areas, because the space itself is relatively small.

And Nancheng District will undoubtedly be the main attack point of the zombies, the number of mines here is the largest, 300,000 mines are buried here, forming a large sea of death, of which only one road can be passed, but ordinary people can't see it at all.

Originally, Ye Fan wanted to simply lay out its millions of mines, but after thinking about it, it was not feasible, the leader of this zombie group should be wise, as long as he concentrated a few attacks, too many mines might not be able to work.

And now the money in his hand is only 7.3 million, Ye Fan still has to wait for the new arms of the Air Force, and he has to arrange the Prism Tower and the giant cannon, so he can't spend all the money.

The newly produced artillery units were also arranged.

Outer town, a parking lot near the inner city part.

The surrounding area has been under martial law, and the residents' cars have been forcibly ordered to leave, and this place has been arranged as an artillery position by Ye Fan.

The fifty cannons were all facing south.

Because of the three directions of east, west and north, it is impossible to have too large a wave of zombies, mortars and 107 are enough, and the real main battle location is still in the south.

The huge muzzle of the cannon flickered with a faint cold light, and the accuracy of all the guns had been precisely adjusted, and there had been detailed arrangements for which area each cannon was responsible for.

Artillery is responsible for long-range, and at medium and close range is 107 rocket artillery and mortars.

One hundred Type 63 107 rocket launchers have been lined up, and the direction of the main attack is still south, but this thing is flexible and lightweight, and the firing direction can be adjusted at any time.

The same goes for mortars, the angles are adjusted.

Behind the artillery positions here, boxes of spare ammunition have begun to move to this side.

This was prepared by Ye Fan after the production of artillery, and the spare ammunition was a big problem, and it was impossible to run out of bullets at a critical moment in the battle, so Ye Fan spent more than one million gold again to equip the troops with a large amount of reserve ammunition.

Two-thirds of the 18 million gold has been spent, and there are still 6 million gold left in the money in hand.

This also made Ye Fan see the price of war, fighting is fighting money.

Because of the dense minefields outside the city, it was impossible for Ye Fan's tanks and armored vehicles to go outside the city to participate in the war in the early days of the war.

However, these vehicles also have their uses, armored vehicles and tanks are deployed in the city, and the vehicles have anti-aircraft machine guns, and their main role is air defense.

This time we have to face a flock of hundreds of thousands of mutant birds, in fact, the pressure of air defense is very great.

Ye Fan originally had thirty tanks in Dawning City, and later produced five more in Jindu, making a total of thirty-five tanks.

And there are one armored vehicles per platoon, three for a company, and eleven for a battalion, because there are also direct platoons and guard platoons.

One regiment is thirty-five, but among Ye Fan's three regiments, the third regiment is not equipped with armored vehicles, and the second regiment is not fully equipped, and the total number of armored vehicles is sixty at present.

In addition to armored vehicles and tanks, there are also Thunder off-road vehicles, which are also equipped with anti-aircraft machine guns, and there are more than 40 of these vehicles here.

There were also more than a hundred anti-aircraft machine guns on various vehicles, scattered throughout the city.

At the intersection of every street, in front of every important area, there are powerful chariots.

Ordinary residents are forbidden to approach chariots, and the Dawning Army has issued a strict order, starting from the morning of the fifth day of the new year, the whole city will enter a state of martial law.

Except for orders from the army, all residents were forbidden to leave their homes and go out into the streets, and no one was allowed to disobey orders, otherwise they would be severely punished or even shot.

These adventurer squads such as Qin Yumo asked to participate in the city defense battle, but they were also rejected by Ye Fan.

They weren't needed to besiege Dawn, and if adventurers were really needed, the city would have fallen.

But at this moment, the survivors are still somewhat useful.

On top of the ten-meter-high ice wall, they began to spread sand on it.

The role of the sand was to prevent the soldiers from falling behind the walls.

The project was supposed to start on the second day of the Lunar New Year, but it has not been completed until now.

Ye Fan walked up to the city wall in curiosity and found that the survivors were actually building sandbags.

Ye Fan couldn't help but walk over when he saw that the newcomer Zhao Xiaoman was busy with her subordinates.

"Xiaoman, why are you working so hard?"

"It's not hard, what is the evolution doing this little work, and besides, don't you think the sandbag is very useful? It's tighter than the battlement, and if someone shoots at this place on the other side, the warrior has an extra life support here. ”

Although Ye Fan felt that zombies should not be able to shoot, it should still be better than not having this sandbag.

And looking at Zhao Xiaoman, it seems that he is competing with people, just like working.

Ye Fan glanced into the distance, and saw that not far away, Qin Yumo's apocalyptic mountain team was also busy.

The two girls occasionally looked at each other in the air, and there seemed to be sparks flickering.

"Is this because I'm jealous? Unfortunately, it's still a little hard for you to get me!"

Ye Fan shook his head slightly, turned around and walked down the city wall.

Seeing that the survivors were full of energy, Ye Fan sometimes wondered if it would be more conducive to cohesion of the people's morale and a greater sense of belonging to Dawning City.

After getting off the city wall, Ye Fan saw his sister Ye Luo again, and walked here with the photographer.

A few days ago, because the zombie group left, it was impossible to track and shoot, and the program broadcast by the TV station returned to normal.

Occasionally broadcast the labor of the survivors, but the combat readiness is not broadcast, what if the zombie horde does not come?

But today it has been confirmed that the zombies are coming, so the TV station has come out again, but the plan is to broadcast it from tomorrow.

Ye Fan has already said that this time the defense of the city will be broadcast on TV, and he will show his strength to all those who can see the Dawn Terrace through this battle.

In the past, there were no publicity channels, but with the gradual establishment of TV stations at various bases, such a good opportunity should not be missed.

Some weapons are not worth secrecy, such as cannons and tanks, whether you keep them secret or not, others know about them, and there is no secrecy value.

And the occasional appearance of some high-end weapons can also deter those who are ambitious.

It can also show other survivors the strength of Dawning City, which is also conducive to personnel recruitment.

Ye Fan could even be sure that after this battle, Dawning City would definitely usher in a peak period of recruiting people again.

Although the three large bases in the province have millions of people, the number of people in the other small bases and survivor gathering points is more than the three large bases.

There are more than a dozen cities in the province, and almost every city has a base of considerable scale, and Dawn City, the Liberation Army, and the Storm Army are just the three larger ones.

Seeing Ye Fan come out, Ye Luoxing rushed over.

"Brother!"

"Xiao Luo, why did you come out so early? Didn't you tell you that it would start playing tomorrow?"

"I'm here for you. ”

"What are you looking for me?"

"Don't you even watch TV? The Guangfu Army said that in view of the crisis situation on our side, they have sent 5,000 elite troops to come over to help us in the defense, and these 5,000 people set off from the Daqingshan Prison Base yesterday morning, and it is estimated that they will arrive in Dawning City early tomorrow morning, so that we can prepare for contact. ”

"Oh! The Liberation Army sent people to help us defend us? Or do they have such good intentions?"

Ye Fan instinctively felt that it was impossible, but suddenly realized that it was wrong.

Only the zombie group knew about the sudden change of route, and the Restoration Army and the Storm Army didn't know about it at all.

Maybe in their hearts, the side of Dawn City will not be attacked at all, all of this is Ye Fan's tricks.

Then the origin of these 5,000 people is very suspicious.

Ye Fan thought for a while and showed a smile: "Since you are here, then you are warmly welcome." ”
