I take the system Wanjie to pick up garbage

Just when Liu Jiangtao was excited, he suddenly heard a shrill siren from the castle.

At the same time, the black widow also appeared beside him:

"Commander, a large group of zombies have been found in the distance, and we are still an hour and a half away. Commander, please be prepared."

Having said that, the Black Widow glanced at the surrounding empty city walls and said:
"Originally, we still have a fourth-level city wall, and even a defense mechanism, but those things are temporarily unusable due to disrepair. We also ask the managers to upgrade the city wall in time, and train a large number of soldiers to survive."

Although it was an indifferent voice, Liu Jiangtao's blood boiled when he heard it.

After so many years, finally someone of the opposite sex who has no blood relationship with him cares about him.

Although this opposite sex is only a product of genetic technology.

However, Liu Jiangtao didn't care.

"Don't worry, I'm here, no accident."

At the same time as the voice fell, Liu Jiangtao directly clicked on the fifth-level city wall.

Originally, the level of the city wall could not be higher than the level of the castle.

However, because the city wall is a reward from the diamond gift pack, it can be used directly.

However, if you want to upgrade to the sixth-level city wall, you need to upgrade the sixth-level castle first.

"Upgrade the second-level tank factory, upgrade the second-level shield arsenal."

"Produce sixty repeaters."

After speaking, Liu Jiangtao walked into the control room of the second-level castle.

The control room of the second-level castle, well, let's call it the city lord's mansion.

The second-level City Lord's Mansion is a two-story building.

The small building on the second floor looks like a commercial house with an attic.

The first floor is still a hall.

There is a huge light curtain in the hall.

All the information of the entire war castle is displayed on the light curtain.

Turn on the light curtain, zoom out the map, and then, what appears in front of Liu Jiangtao is the map of the whole world.

The whole world is a square world.

It's like a continent.

Liu Jiangtao found that his small world was in the center of the mainland.

Well, although it is not the most central, it is relatively close to the center.

According to the normal situation of the game, the closer to the center, the more good things you get.

The closer to the center, the more energy you get.

Of course, the closer you get to the center, the greater the danger.

For example, zombies, the number of zombies in the center and the level of zombies will be relatively high.

At the same time, the castles in other places will always keep an eye on the central castle. Once the central castle's combat effectiveness is not strong, it will be killed.

Of course, Liu Jiangtao didn't know that the energy collectors in his area collected energy at a rate of one point per second, but the speed of energy collection at castles far away from the center was twenty points per minute.

Basically a little bit of three seconds.

Of course, this is only a first-level energy collector.

Think of Liu Jiangtao's secondary energy collector, now it is two points per second.

The speed is still pretty good.

Entering the City Lord's Mansion, Liu Jiangtao directly used the city wall.

The first-level city walls are earthen walls.

Can only play a small defensive role.

The second-level city wall is still an earthen wall, but it is much thicker than the first-level earthen wall.

The third-level city wall is made of blue bricks, half a meter thick.

The fourth-level city wall is also made of green bricks, but it is as thick as one meter.

When Liu Jiangtao first accepted the war castle, the defense mechanism he opened was this kind of castle.

As for the fifth-level castle, it is a two-meter-thick masonry wall.

The sixth grade is four meters thick.

However, after reaching the seventh level, it is a steel castle.

Of course, at that time, even if there is no powerful defensive weapon, even if you rely on the steel castle, ordinary zombies will not be able to get in.

As Liu Jiangtao used the fifth-level city wall, a row of three-meter-high and two-meter-thick masonry walls immediately appeared on the outermost periphery of the castle.

At the same time, on the city wall, there are machine gun installations one by one.

These machine gun installations are already activated.

Every four meters, there is a machine gun bunker, and every ten meters, there is a fort behind the city wall.

There are heavy guns on the fort.

The two-meter-thick city wall is enough for Liu Jiangtao to use various methods on it.

These machine guns and heavy artillery are automatically carried when the city wall is upgraded.

However, if these machine guns and heavy artillery are damaged and you want to repair them, you need to consume energy.

Of course, there are machine guns and heavy artillery, but they also need energy to use them.

It can be said that in this world, without energy, there is nothing.

An hour later, the shield arsenal and chariot factory were successfully upgraded.

Looking at the time, it was still half an hour before the zombies came over.

"Produce thirty second-class tanks, that is, long-range tanks."

"Reproduce [-] second-level shield soldiers."

"Upgrade the gun factory to level two."

"Upgrade the second-level castle to the third level."

Following a series of orders, Liu Jiangtao produced [-] rounds of ammunition again.

Five hundred bullets are enough.

When upgrading to a third-level castle, Liu Jiangtao saw a message.

At the third-level castle, the commander can only use short guns and submachine guns, and the highest is the AK47.

However, when the castle is upgraded to level four, domestic firearms can be used.

And the higher the level of the castle, the higher the firearms used.

At the same time, the AK47 in Liu Jiangtao's hands can shoot only a few hundred rounds.

Half an hour later, there was a roar in the distance.

Then, a large group of zombies appeared a hundred meters away.

On the city wall, Liu Jiangtao is holding a gold AK47 with a faint smile on his face.

At the same time, there were rows of soldiers on the city wall.

Behind the city walls are thirty long-range chariots.

As for short-range chariots and shield soldiers, Liu Jiangtao sent them out.

Although in the zombie group, this is a bit of a rhythm of death, but only in this way can the first-level soldiers evolve into second-level soldiers.

The same tank is so unreasonable, as long as enough zombies are killed, it can change from a first-level short-range tank to a second-level long-range tank.

This is a very unreasonable and unscientific magical setting.

"boom."

With the firing of a bullet, a kind of sniper began to attack.

At the same time, the shield soldiers and short-range chariots also rushed out at this moment.

They were outside the city wall, and now they rushed towards the zombie group.

The war, from the very beginning, was intense.

However, this time, Liu Jiangtao was very calm.

With more than 200 million energy in hand, these zombies can only be regarded as scum.

half an hour.

This time, in just half an hour, Liu Jiangtao killed all the zombies.

The moment he killed all the zombies, a voice came to Liu Jiangtao's mind.
