In addition to having a set of advanced power armor, this hand must also have superhuman physical strength and reaction speed.

The special service team that retreated to the upper floor of the second layer of the fortress immediately prepared for battle, in case the insects launched an attack at this juncture, regardless of casualties, the special service team could at least kill a group of giant insects and buy a little time for the front-line troops.

Fortunately, despite their madness, bugs are still creatures by nature, and they are born with an extreme fear of fire, and no giant bug dares to rush into the blazing iron fire.

The defenders' movements were fast, and after a while, Ye Han saw a group of defenders rushing out of the fortress building on the front line, quickly passing through the short street and disappearing.

Then he saw a section of the bridge protruding from the fortress building opposite, and at the same time, there was also a section of the bridge deck sticking out of the building under his feet, and the two sections of the bridge converged in the air to become a "flyover" across the short street.

After the bridge was fastened, a platoon of defenders rushed up to the bridge at great speed, and retreated into the fortress building at their feet.

Ye Han wanted to see if other directions were also evacuated with this kind of overpass, but the special design of the fortress building blocked his vision, and he only imagined out of thin air that each building would have one or even several overpasses to evacuate the defenders.

In addition to the ground and the overpass, Ye Han also knew that there were tunnels connecting the fortress towers, and there must be some defenders who withdrew from the front line through the tunnels.

By three different means, the defenders were all withdrawn from the front line in just a few minutes.

However, the first-line defenders did not withdraw to the second line, but directly withdrew to Funing City to rest.

After a series of battles, the defenders on the front line need to rest physically and mentally, while the defenders on the second line of defense are always ready to work and are about to engage the swarm head-on.

The second line of defense is not a replica of the first line of defense, and on the contrary, the second line of defense has more deployments against swarms.

As soon as the first-line defenders were withdrawn, the three-way junction between the two lines of defense changed.

The soldiers who were originally guarding there quickly set up barricades, blocked the short street and quickly withdrew, leaving no one behind, only tanks stood there alone.

The other adjacent intersection is not a tank, but a wheeled assault gun, and the other intersections are what Ye Han can't see, but it is conceivable that those combat vehicles are definitely inseparable.

And the combat vehicles guarding the fork in the road are not facing the short street, but behind the curve!

If the swarm rushes in, it must first carry the fire point facing the short street, and only by breaking through the fire blockade can it be possible to rush through the three-way intersection.

The swarm then has to face the various combat vehicles guarding behind the fork in the road.

Ye Han was pondering that one car at each intersection was a bit insufficient, when he heard a rumbling sound coming from below.

When the probe took a look, a puff of black smoke erupted from behind the butt of the tank blocking the intersection, and then slowly reversed, and after driving a distance, it made a 180-degree turn, leaving a puff of black smoke and driving away directly...... Drove away!

Isn't this going to care about this intersection?

Looking at the other side, the assault guns blocking the road were also withdrawn like tanks.

Ye Han couldn't help but sigh, in fact, it was right to withdraw at this time, there was a fortress building on top of it, and it really didn't make much difference whether there were those cars or not.

However, he obviously thought about it, and both tanks and assault guns stopped after reaching the intersection at the end of the short street, adjusted their positions, and stayed there to prepare for battle.

There is nothing difficult to understand, guarding below must confront the insect swarm head-on, and guarding the fork in the back is to attack and retreat, and to be flexible.

After the combat vehicles were withdrawn, there was also a little change on the short street downstairs, and rows of steel frames pointing diagonally in front of the originally smooth street slowly rose, and each steel frame was erected with a row of sharpened hollow steel pipes, which looked particularly like the rejection of horses in movies and television.

Ye Han's mind was a little confused, all his knowledge of the fortress city came from internal information, but most of the information was a simple overview, and few inconspicuous details were described.

What was happening in front of his eyes at the moment was something he had never known before, and it was clear that his knowledge of the fortress city was too shallow and one-sided...... Well, I don't know if the short street into the city has a similar arrangement!

Ye Han took a curious look and found that the short street leading to the outside of the city was as usual, and there was no change at all.

He couldn't help but sigh, this is digging a pit for the insect swarm, how can such a city be so easy to break?

Ye Han had seen the dungeon breached by the insect swarm with his own eyes, but he had never heard of any fortress city that had been breached by the insects...... Who says fortress cities aren't as safe as dungeons?

The flames burning in the distance were being extinguished, worried about the movement of the insect swarm, Ye Han took the initiative to connect the data of the command center, and obtained the picture transmitted by the drone from the command center - sending drones or using satellites to observe the enemy's movements is an indispensable means of reconnaissance in modern warfare, if the Funing command center does not do this, it can only mean that the command level here is not qualified at all!

So he doesn't need to ask at all, he can directly access the data and get what he cares about.

Of course, this is also Ye Han's authority is high enough, if there is no corresponding authority, it is difficult to say whether he can access the command center.

Through the lens of the drone, Ye Han saw that there was almost no insect activity in the outskirts of the city, and the closest bugs to the city were also a few kilometers away.

They couldn't stay away, because this distance happened to be the area covered by the incendiary bombs, although it was not 100% covered, but there were also 4 or 50 percent, and there were countless bugs that died in this area, and the swarm couldn't retreat if they wanted to.

Ye Han couldn't help but breathe a sigh of relief, it seems that the insect swarm will not attack for the time being, which is definitely good news for the defenders - the longer it drags on, the more prepared the defenders will be, and as time passes, the original heavy rain will become light rain, and the light rain will become cloudy, and after a while, I am afraid that even the dark clouds will disperse, and at that time, the insect swarm will lose the cover of the clouds, and then pass through the space station here, and provide air support for Funing for a period of time.

By then, the swarm will have a hard time!

It's like hearing Ye Han's heart, here Ye Han has a mess of thoughts in his mind, the insect swarm in the drone lens has already spread the worm legs, rushing towards Funing in groups, and the fifth attack has officially begun.

Ye Han realized that there was no fire on the battlefield...... It turns out that the swarm has been standing still to wait for the flames to go out!

This discovery made Ye Han very speechless, the incendiary bomb is very powerful, but it won't leave such a serious psychological shadow on the insects, right?
