If you cooperate with the defense facilities to defend, the number of infected bodies that the road army can fight against is definitely more than two million, and it is the kind of head-on.

It's just that this time the Lu Army and others have to face more than six million infected bodies, and there is absolutely no way to win in a head-to-head situation.

So what kind of strategy is used in defense is particularly important, and it is related to the success or failure of the defense.

"Brother Lu Jun, they are here and they have entered our best attack range!" Xiao Wan rode a bloodthirsty king bat to the top of the Lu Jun and reported.

At this time, the first echelon of the infected body group was indeed only more than 500 meters away from the sky, and it would be close to them without dealing with them.

Another point is that they have dug ground traps in the large open space more than 500 meters in front.

It's best not to let the infected group step into the trap too early, or it will fill up soon.

"Okay, let's start." Lu Jun nodded, and then slammed his hand, "Fire!"

With the order issued by the road army, the more than 300 spiked guard towers behind them quickly responded, shooting a huge crossbow arrow, forming a rain of arrows, flying hundreds of meters and falling into the infected group.

Although these crossbow arrows are made of wood, each of them is more than one meter long, and the extreme rate of fire combined with the momentum can penetrate several infected bodies instantly.

Counting that each spiked guard tower will shoot ten crossbow arrows, more than 300 spiked guard towers are more than 3,000, and a wave of attacks can kill more than 20,000 infected bodies.

Although this loss is not a big deal for the huge group of infected bodies, in fact this level of damage is already considerable.

Moreover, after killing the infected body, the remaining crossbow arrows can also form a small isolation belt, which can slightly block the progress of the infected body group.

As the second wave of crossbow arrows was about to be fired, the slave laborers immediately raised the fire guard and the drawing artillery to the high platform around the spiked guard tower, so that the two defensive facilities could exert the greatest effect.

A few seconds later, the fire guards and the plucking artillery also fired one after another.

The fire guard's rate of fire is 20 rounds of energy bombs per second, and 3,900 fire guards are more than 70,000 rounds per second.

The firepower net formed by this attack intensity is visible to the naked eye, and instantly enveloped the first echelon of the infected group like a large net.

Not to mention drawing artillery, their range is farther than the fire guard, and their power is stronger than the fire guard. One blow is an infected body.

The only drawback is that the rate of fire is relatively slow, and only one energy shell can be fired every two seconds.

But fortunately, they have more than two thousand, which can make up for the problem of insufficient rate of fire.

Moreover, the fire guard and the plucking artillery attack have a strict division of labor. For example, the fire guard only attacks the infected body at the front, and the plucking artillery attacks the infected body that cannot be seen behind.

This can ensure that the firepower of the two defensive facilities does not overlap and maximize output, and it can also make the infected body group have a fault, and the later infected body cannot be supplemented in time.

In front of the fire guard and the energy bombs that fired the artillery, the infected body died like this at tens of thousands per second, falling down like cutting wheat.

This kind of damage is actually very exaggerated, tens of thousands per second, ten seconds is close to hundreds of thousands.

What Lu Jun and the others had worked so hard and took several hours to accomplish by the infected body group, now it only took twenty seconds to complete, it is simply the difference between heaven and earth.

Seeing this scene, Lu Jun was also very emotional, thinking to himself that even in the end times, technology is still very strong.

After all, neither his dinosaurs nor his abilities can cause this level of damage in a short time.

The only downside is that these gadgets are relatively inconvenient, they take a long time to erect and require manual maintenance.

Moreover, the energy bombs used need to be purchased by the Lu Army from the trading module, which has almost used up all the Dragon Coins, and the overall investment is relatively large.

If it weren't for the Lu Army's certain accumulation and great family business, these things would not be needed at all.

If this continues, it is estimated that 600,000 infected bodies can be killed in one round of ammunition.

With five rounds of ammunition reserves in the road army, it should be able to kill nearly three million infected bodies.

At that time, with ground traps and the dinosaurs of the road army, it will be difficult to kill the remaining two or three million, but there is definitely a chance.

If the infected group can be wiped out in this way, the casualties on the side of the road army are not likely to be very large, and it is a situation that the road army would like to see.

Looking at the infected group being beaten up, all the rebels showed knowing smiles. They were very proud of being able to survive the attack of so many infected bodies.

At the same time, their momentum is also rapidly rising, and it is estimated that when they play, they will be as powerful as a bamboo.

The fifth class people who watched all this through the remote observation board were a bit suffocated, because they hadn't seen this kind of technology since the end of the world.

It is no exaggeration to say that even before the end of the world, it is difficult for the human regular army to have this level of firepower.

"They are too perverted. Fortunately, we didn't take the lead in the attack, otherwise it is estimated that there will be no scum left..." Zhiwei sighed again.

If he thought that the old fifth boasted that the road army was so powerful because he was afraid of the road army, he didn't believe in the old fifth.

At this time, he was absolutely convinced of what the old fifth said, and felt that the Lu Jun was stronger than the old fifth said.

"If this continues, the infected group will probably be unstoppable. Their lethality is too terrifying." Baqi whispered beside him.

As a senior member of Babuzhong, he was also the first to see this kind of firepower.

At this time, he has changed from being vigilant to the resistance army, because the resistance army has too many methods...

"Don't be so depressed, the infected group will definitely not just fall down like this, there are definitely future moves, many infected have not taken action yet." The fifth person looked at the remote observation board and calmed everyone.

In fact, he didn't know if the infected group had any back-ups, but his instinct told him that things would never be that simple.

Sure enough, the moment the fifth child finished speaking, an unexpected situation occurred.

I saw that the infected body had just been killed by fire guards and drawn artillery. A mental barrier appeared above the infected body group, blocking the front of the infected body group, blocking all energy bomb attacks, and it has not been for a long time. dissipate.

This scene awakened both Zhihui and Baqi, staring at the remote observation board with wide-eyed eyes, and wanted to see clearly what happened.

The rebels on the battlefield can more intuitively feel the defensive nature of the mental barrier.

"What's the situation?" Xiaowan flew to the top with her four wings, giving herself a broader vision.

Lu Jun frowned slightly, opened the Magic Eye and Data Eye and scanned the barrier in front of him, but unfortunately nothing was found...
