The protagonist carefully studies the tentacles and even takes them outside the lair to conduct constant experiments.

It doesn't take until dark that the protagonist roughly understands its function. By touching the hollow tail of the radar destroyer's tentacles, he was able to pick up sounds within a diameter of nearly ten meters in the vicinity.

The farther away you are, the weaker the sound you receive, and at very close range, you can hear it with extreme precision, even the most subtle sounds.

But other than that, there is nothing else surprising about this pair of tentacles.

Although the ability of the tentacles to receive sound is unique, it is not important in the Divine Envoy King Legion with the Flying Knight's aerial reconnaissance, and the accuracy and intuitiveness of sound wave detection are far less than that of aerial reconnaissance.

It can also be used to make up for the situation that the flying knights can't go out at night or the detection effect is not good.

The protagonist feels that this tentacle must have other more powerful detection capabilities on the Radar Destroyer, after all, the Radar Destroyer has groped all the way to this place from a long distance away from the [bridgehead], and its detection range must be far greater than the ten meter effective range that the protagonist has measured so far.

Obviously, like the Mystic Orb, the protagonist hasn't done much research on the tentacles, but it's more useful than the Mystic Orb, at least for now.

The Mystery Orb only explodes on its own, and the tentacles can play some role as a scout.

The protagonist soon decides to build a listening station on top of the [bridgehead], placing a tentacle in between, and making sound insulation from plant fibers on the four walls of the house.

This listening station can provide early warning to [Waterfront City] at night, and can also be used as a laboratory for further research tentacles.

To this end, the protagonist also set up a special squad of monitoring teams, which are specifically responsible for monitoring tentacles.

Because the sound information transmitted from the tentacles is too large and complex, and the amount of information is huge, even the protagonist has to get used to it, so at present, this listening team has to undergo adaptation training first, and it is not yet able to take up the post.

The construction of a soundproof wall in the listening room is also to minimize noise interference and avoid increasing the burden on the monitor.

- I'm the dividing line -

On the second day after Roll led the 1st Legion to destroy the Radar Destroyer team, the Flying Knights detected the southbound Destroyer army and suddenly stopped advancing.

Maybe they stopped advancing yesterday, but yesterday the Flying Knights were all near the battlefield and didn't detect the movement of their army.

It wasn't until this morning that the Flying Knight, who was on routine reconnaissance, noticed the anomaly.

This also convinces the protagonist that the Radar Destroyer is the eyes and ears of this army, determining the direction in which the army is headed. So after the loss of the Radar Destroyer, the Destroyer army was at a loss.

It's just strange that the flying knights have never seen the Radar Destroyer in the battlefields before, and even the Radar Destroyer army that attacked the western part of the Ant Barbarian Nation at the same time did not have a radar destroyer.

Is it a coincidence that only the Destroyer army that is attacking southward has a radar destroyer for the first time, and the target happens to be the stronghold of the Divine Envoy King's legion?

In the afternoon, the Flying Knights found that the Destroyer army had finally returned to its path after a long stay.

Previously, the route of this Destroyer army was to gradually turn from south to southeast, drawing an arc and gradually approaching the [bridgehead].

After losing the Radar Destroyer, the Destroyer army re-advanced along the Ant Path, and they headed southwest, ahead of them was the main nest of the Great King's Council faction, the southern branch of the Ant Barbarian Nation of the original Paved Road.

The protagonist does not take any new military actions, and the large army is stationed in the [bridgehead] to constantly strengthen the city defenses.

As for the decisive battle between the Destroyer army and the King's Council faction, the protagonist only asked the Flying Knights to step up their reconnaissance and did not try to interfere.

- I'm the dividing line -

Two days later, the Destroyer army arrived at the main lair of the King's Council faction.

Previously, the main force of the Great King's Conference faction, the remnants of the Northern Expeditionary Army of the former Big-headed Ant Kingdom, gathered the military essence of the entire territory, but was easily defeated by the Destroyer's partial division near [Target A], and the remnants were trapped in [Target A] and could not get out.

At this time, the main nest of the Great King Conference faction has few soldiers, and the troops that have been temporarily cobbled together from the deputy nests from various places are not very large.

The Destroyer army was slaughtering from east to west, and the King's Council faction was unable to send troops to resist in the field, so they could only sit back and watch as the secondary nests along the way were breached, the ant people were slaughtered, and the corpses were transported away.

The Destroyer army moved quickly, and soon arrived at the main lair of the King's Council faction, and immediately launched a fierce invasion.

The forward troops did not wait for the arrival of the main force in the rear to rush to attack, and the defenders of the King's Council faction also resisted desperately.

By the time the Destroyer's army arrived and attacked, the lair's resistance was quickly extinguished, and the Flying Knights observed that the Destroyer had begun to carry corpses north.

The main nest of the King's Council faction only persisted in resisting for half a day before it was destroyed.

Now, the Northern Expeditionary Force trapped in [Target A] is the only remnant of the King's Council faction, and even the old Big-Headed Ant Empire.

But they obviously couldn't hold out for long, and the Destroyer army divided a part to transport the corpses, and a few small units to attack the weakly defended side nests in various places.

The army has been marching eastward without stopping, aiming at [Target A] and the [bridgehead] behind [Target A].

The remnants of the Northern Expeditionary Army could not even defeat the breakout by monitoring the small force of the Destroyer who surrounded them, and in the situation of lack of food and food, they were powerless to stop the Destroyer army.

At the juncture of the imminent collapse of the King's Council faction, the protagonist has foreseen a major war coming to [Bridgehead].

At this time, there is no longer any force on the north bank of the river that can act as a buffer, and the Divine Envoy King must face this powerful enemy.

In just one year, this enemy has brought the undisputed overlord Paving Ant Barbarian State on the north bank of the Great River to the brink of collapse, which is a great feat that the protagonist asks himself that the Divine Envoy King Legion cannot do.

But the protagonist is not afraid, and the army of divine envoys he has assembled from scratch is not easy to get along with.

After unifying the basin on the south bank of the Great River, the Divine Envoy King's army had a solid rear, a growing economic base, and technologies such as metal smelting that other ants did not have.

The war potential of the Divine Envoy King's legion is also extremely impressive, and if there is a need, it can mobilize a million troops in an emergency.

At present, the Divine Envoy King Legion already has 32 elite legions armed to the teeth, plus garrison legions in various places, there are enough 100,000 tigers.

In addition, it is currently a defensive operation, and the front line of [Bridgehead] and [Waterfront City] is the only crossing for the enemy except for winter, as long as these two fortresses are held, the Destroyer will not be able to threaten the foundation of the Divine Envoy King's legion!
