One Thousand Seven Hundred and Nine Psychological Shadows

In addition to having an advanced power armor, this move also requires superior physical strength and reaction speed. Except for the special service team, other defenders may not be able to do it even if they wear armor, and can only watch.

The special service team retreated to the second-floor fortress building and immediately prepared for battle. If the bugs ignored casualties and launched an attack at this critical moment, the special service team could at least kill a group of giant bugs and buy some time for the front-line troops.

Fortunately, although the bugs were crazy, they were still biological creatures in essence. They were born with an extreme fear of fire. No giant bug dared to rush into the blazing iron fire.

The defenders moved quickly. After a while, Ye Han saw a group of defenders rushing out of the front-line fortress building, quickly passing through the short street and disappearing.

Then he saw a section of the bridge deck sticking out from the fortress building opposite. At the same time, a section of the bridge deck also stretched out from the building under his feet. The two sections of the bridge merged in the air and became a "street overpass" across the short street.

After the bridge was fastened, a row of defenders rushed onto the bridge at a very fast speed and retreated to the fortress building at their feet.

Ye Han wanted to see if other directions also used this kind of skybridge to evacuate, but the special design of the fortress building blocked his sight. He could only imagine that each building had one or even several skybridges to evacuate the defenders.

In addition to the ground and the skybridge, Ye Han also knew that there were tunnels connecting the fortress buildings, and some defenders must have evacuated the first line through the tunnels.

Through three different means, the defenders all withdrew from the first line in just a few minutes.

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

After a series of battles, the first-line defenders needed to rest physically and mentally, while the defenders on the second line of defense were always waiting for the opportunity to fight the insect swarm head-on.

The second line of defense was not a replica of the first line of defense, but on the contrary, the second line of defense had more deployments against the insect swarm.

As soon as the first-line defenders withdrew, the three-way intersection between the two lines of defense changed.

The soldiers who were originally guarding there quickly set up roadblocks, blocked the short street and quickly withdrew. No one was left, only the tank was guarding there alone.

The other intersection adjacent to the road was not a tank, but a wheeled assault gun. Ye Han could not see what was at the other intersections, but he could imagine that they must be inseparable from those combat vehicles.

Moreover, the combat vehicles guarding the fork in the road were not facing the short street,

but guarding behind the bend!

If the swarm rushed in, they must first withstand the firepower point facing the short street. Only by breaking through the firepower blockade can they rush through the three-way intersection.

Then, the swarm will have to face the various combat vehicles guarding behind the fork in the road.

Ye Han was thinking that one car at each intersection was not enough, and he heard a rumbling sound coming from below.

Looking out, a puff of black smoke came out from the back of the tank blocking the intersection, and then it slowly reversed, and after driving a distance, it made a 180-degree turn, leaving a puff of black smoke and drove away directly... drove away!

Is this not going to take care of this intersection?

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

Ye Han couldn't help but sigh. In fact, it was right to withdraw at this time. With the fortress building here, it really didn't make much difference whether there were those vehicles or not.

But he obviously thought wrongly. No matter whether it was a tank or an assault gun, they all stopped after reaching the intersection at the end of the short street, adjusted their positions, and stayed there to prepare for battle.

This is not difficult to understand. If you guard downstairs, you must face the swarm head-on, while guarding the fork in the road behind, you can attack or defend, and be flexible.

After the combat vehicles withdrew, there was a little change on the short street downstairs. Rows of steel frames pointing obliquely to the front slowly rose on the originally flat street. Each steel frame was supported by a row of sharpened hollow steel pipes, which looked particularly like the chevaux de frise in movies and TV.

Ye Han's mind was a little confused. All his knowledge of the fortress city came from internal information, but information was mostly a simple overview, rarely describing insignificant details.

Everything that was happening in front of him was something he had never known before. Obviously, his understanding of the fortress city was too superficial and one-sided... Well, I wonder if the short street leading into the city has a similar arrangement!

Ye Han took a curious look and found that the short street leading out of the city was as usual, without any changes.

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

Ye Han had seen the underground city broken by the swarm of insects with his own eyes, but he had never heard of any fortress city being broken by insects... Who said that the fortress city was not as safe as the underground city?

The flames burning in the distance were extinguishing. Worried about the movement of the swarm of insects, Ye Han took the initiative to connect to the data of the command center and obtained the pictures sent back by the drone from the command center. Dispatching drones or using satellites to observe the enemy's movements is an indispensable means of reconnaissance in modern warfare. If the Funing Command Center did not do this, it can only mean that the command level here is not qualified at all!

So he didn't need to ask at all, just access the data directly to get what he cares about.

Of course, this is also because Ye Han has a high level of authority. If he does not have the corresponding authority, it is hard to say whether he can access the command center.

Through the drone's lens, Ye Han saw that there were almost no insect activities in the edge of the city, and the nearest insects were several kilometers away from the city.

They had no choice but to stay away, because this distance was exactly the area covered by incendiary bombs. Although it was not 100% covered, it was at least 40-50%. Countless insects died in this area, and the swarm had no choice but to retreat.

Ye Han couldn't help but breathe a sigh of relief. It seemed that the swarm would not attack for the time being. This was definitely good news for the defenders. The longer it dragged on, the more prepared the defenders would be. Moreover, as time passed, the heavy rain turned into light rain, and the light rain turned into cloudy days. After a while, I'm afraid that even the dark clouds would disperse. At that time, the swarm would lose the cover of the clouds. At that time, the space station passing by here could provide air support for Funing for a period of time.

By that time, the swarm would have a hard time!

As if Ye Han's voice was heard, Ye Han's mind was full of messy thoughts. The swarm in the drone camera had spread its legs and rushed towards Funing in groups. The fifth attack was officially launched.

Ye Han then realized that there was no flame on the battlefield... It turned out that the insect swarm had been waiting for the flames to die out!

This discovery made Ye Han speechless. The incendiary bombs were powerful, but they shouldn't leave such a serious psychological trauma on the insects, right?
