The rock where the bridgehead is located is a stone about the size of a bathtub. The upper part has a gentle slope to form a platform, while the lower part has an extremely steep slope, like a curved pyramid of ancient Egypt, except that it does not have a significant spire.

The bridgehead was built on this stone, and the first wall line of defense encircled the stone platform, enclosing the relatively gentle top of the stone platform.

The height of the wall is on average half a meter above the ground, and it faces land on three sides, only the side adjacent to the water, and the water cannons of parasitic dragon lice will be able to shoot up to this height and impact the city wall.

But on the other side of the water, where the shrubs grow on the edge of the stone platform, an ant mound tightly wraps the trunk of the shrub, the walls of this ant mound are thick enough to resist the repeated attacks of the parasitic dragon lice water cannon, and the dense leaves of the shrubs hanging down the water surface can also play a role in buffering and blocking.

Therefore, thanks to the terrain, the defenders of the Divine Envoy King's legion did not have to worry about the threat from the water for the time being, and could concentrate on dealing with attacks from both air and land.

But now, it is clear that the threat from the air is enormous. The protagonist watched as the parasitic dragonflies that shifted their targets swooped down again and again, grabbing the powerless Divine Envoy King Warrior into the air and biting them to death, throwing their corpses down, and attracting a swarm of parasitic flies and moths to rob them.

The feeling of the protagonist is both fiery and powerless.

Seeing that on the ground, tens of thousands of parasitic ants are like landslides and tsunamis, carrying a large number of land-traveling parasitic beasts to surge, and the protagonist also knows that the twenty Divine Envoy King Legion teams on the front line will be absolutely unable to resist under the distraction of the air threat.

The protagonist gives the order to retreat in time, saving the lives of hundreds of fighters.

After the order was delivered, the front-line troops alternately covered, braving constant blows from the air, little by little withdrawing the second line of defense of the anthill.

This is also the last line of defense of the bridgehead, if it can't be held here, the protagonist can only take the risk of returning to [Swamp City] through the rope bridge when the enemy controls air and water supremacy, and I am afraid that there will be no survivors for ten miles.

And once it retreats, with the strength of the parasitic army, it will be stationed in the bridgehead, and there will only be one protagonist of the army at hand, and the military god possession will not be able to recapture it. There is only one lone [Swamp City] left in the stronghold of the Divine Envoy King's legion in the swamp region, and the "Swamp Raiders" will be a complete failure.

Therefore, in the will of the protagonist, the bridgehead must be held to the end.

There are also benefits to retreating back to the bridgehead. The main force of the Fourth Army was not damaged, and the morale and confidence of the male commanders were not dampened.

Moreover, the bridgehead walls were thick and solid, with few entrances and exits and ventilation holes, which prevented the threat of the enemy's rampant air force. Even an army with a large number of enemies can only attack from a few passages, and even if the parasitic beasts try to dig through the walls, the strength of the dry ant concrete is not enough for their jaws to penetrate in a short time.

Not long after the last group of Divine Envoy King warriors withdrew to the ant mound, the first batch of parasitic war beasts and parasitic ants had already climbed the city wall and occupied the first line of defense that had been abandoned.

Due to the sheer number of parasitic armies that appeared today, the ground leading to the bridgehead was packed, and the fast parasitic beasts would be blocked by other big men even if they stepped on their bodies regardless of the parasitic ants.

So today, the parasitic war beast was not able to speed up and shake off its slower companions, so they could only huddle together and move forward. Along the way, they also left behind countless parasitic ants and parasites that were trampled to death and injured by large men, and they continued into a road of flesh and blood.

The protagonist leaves the window where he watched the battle, which is small enough to accommodate an ant, and is reinforced with a window made of wood fiber. However, it is not safe, and the enemy can easily break through the slender and fragile windows and attack from here.

A squad arrived and set up a defensive line, and such maneuvers and defenses were staged in every passage and ventilation port of the anthill.

The focus of the Divine Angel King's legion is on two points: the bee entrance and the rope bridge passage.

The bee entrance is built on the side facing the water, sloping upwards, and the opening is near the top of the anthill. This entrance and exit and internal passage are large enough to accommodate two bees in parallel, and it is the largest passage to the outside of the antmound.

In order to facilitate the entry and exit of flying knights and bee mounts, and also to serve as a channel for the enemy's medium-sized war beasts to attack, the Divine Envoy King's legion has a large number of defensive forces here.

The rope bridge passage is the only passage connecting [Swamp City] to the bridgehead, and the rope bridge connected to the bushes has been wrapped in ant mounds, leaving only a small entrance.

Although this entrance is not too large and can only accommodate a bee or a few ants in one direction at the same time, it is close to the ground and water, making it easy to be attacked at the beginning.

Moreover, the rope bridge was also the only retreat of the defenders, and there was no room for error, and the Fourth Army also laid out heavy troops here.

The parasitic army soon covered the surface of the stone like a spreading wildfire, quickly spreading towards the anthill. Following the scent left behind by the warriors of the Divine Envoy King, the parasitic ants soon found the first entrance and exit of the anthill.

In fact, the protagonist has time to fill most of the entrances and exits with stones, which have already been prepared. There is only a large passage such as the bee entrance, and it is difficult for the protagonist to carry large enough stones to fill it.

However, the protagonist doesn't do this, although this way the anthill is temporarily safe, but the parasitic beasts and parasitic ants that can't find their opponents may destroy the antmound.

Although the anthill is very strong, it will definitely be damaged by tens of thousands of enemies, and it may not be able to repair it overnight.

And the protagonist is still unconvinced, he thinks that the gods made the king's army abandonment of the first line of defense before the battle, just because of the loss of air supremacy.

If they engage head-on in the ant mound, the Divine Envoy King's legion will surely make the enemy pay a heavy price and let out a bad breath.

In this way, with the "connivance" of the defenders, the parasitic army began to besiege the anthill.

If viewed from the air, the side supporting the defenders will see a scene that can be called "desperate".

In the air and on the water, the lonely anthill castle has been completely blockaded and surrounded, and on the ground, countless parasitic ants have completely covered the earthy yellow anthill like a tarpaulin, and its original background color is almost invisible. There are also hundreds of parasitic beasts of all kinds crawling around on the ant mounds.

If the anthill were a volcano, perhaps a single eruption would be able to bury so many enemies in Hell at the same time. In addition, the more than 2,000 defenders trapped in it did not seem to see any possibility of defeating the army in front of them.
