A group of scout warriors from the Legion of the Divine Envoy King were scattered across the ground, roughly in a fan-shaped formation, searching and advancing from east to west.

Behind the scouts was the main force in a longitudinal marching column.

These scout warriors are made up of two types of ants, the scythe and the big-headed ant, and they have a clear division of labor.

The Scythe Scouts are in charge of keeping watch on the perimeter, and although their vaunted eyesight advantage is greatly diminished in the darkness of the night, if any insect or enemy dares to sneak attack, they will still use their jaws to teach each other a hard lesson. Outside the cordon, from time to time there are alarmed grasshoppers and so on to jump away, these grasshoppers can not live for a few days, but they still have a full desire to survive, and are not willing to become the belly of ants.

The Big-Headed Ant Scouts are focused on searching for something, touching the ground with their tentacles from time to time, and if they spot something, they will immediately retreat and pass the information to the male ant leader.

After analyzing the information, the leader of the ant squad in charge of the intelligence will send the information to the higher-level commander for reference.

These scouts were collecting pheromones left behind by the Northern Expeditionary Force and the mysterious ants to guide the army in the rear.

Each ant has its own unique pheromone language, and they cannot read the meaning of pheromones of other races, but they can smell their presence.

The Northern Expeditionary Army is composed of big-headed ants, which are of the same origin as the Divine Envoy King Legion, and the pheromone language of the two sides is interoperable, and the scouts can easily distinguish the meaning of the pheromones left by the Northern Expeditionary Army.

As such, the Big-Headed Ant Scouts are responsible for finding and reading these languages, while the Scythe Hunter Scout Warriors are only responsible for guarding the perimeter.

The number of pheromones left behind by the Northern Expeditionary Army was huge and mixed, spreading from the battlefield strewn with corpses in all directions.

The pheromones that extend in the direction of [Target A] are the most, including the signpost pheromones that guide the way, and the very fresh long-lasting pheromones that have just been left for two or three days, and the content is to guide the rout to retreat to [Target A].

There are also a lot of short-acting pheromones that are left spontaneously. Many of the pheromones that spread in all directions are short-lived pheromones, and many of the flavors have dissipated so much that they take a lot of effort to sniff out.

These pheromones are like a book that records a lot of information.

Those long-lasting pheromones that lead to [Target A] in an orderly manner indicate that even after the defeat, the troops in the rear that still remain intact are still withdrawn from the battlefield in an orderly manner and maintain their combat effectiveness. Moreover, the commander of the public security king and other commanders are also trying to re-gather the rout and let them go to [Target A] to gather.

The disorderly short-term pheromones that spread in all directions were apparently left behind by the routs as they fled in all directions, hoping to use them to show their way, tell their companions where they were going, and make a mark to prevent them from getting lost and going back and forth.

The protagonist can imagine the scene of the chaos at that time:

When the main force was defeated by the powerful mysterious ant army, the commanders such as the public security king and the senior brother king who were sitting in the rear of the army knew that they were powerless, so they gave up the idea of counterattacking, and instead commanded the complete and powerful palace troops to cover alternately, and returned to [Target A] as quickly as possible, preparing to hold on to the city.

They may have sent the Imperial Queen's troops to buy time for the army, and these Imperial Queen's troops were destined to go and never return.

At the same time, in order to gather more strength, the kings ordered to leave a guide along the way to guide the rout to return to [Target A], and this lair was the last they could rely on.

However, under the encirclement and interception of the mysterious ant army, most of the scattered Northern Expeditionary Army soldiers were destined to not be able to return to [Target A] smoothly. They fled in a panic in the direction where there were no enemies, leaving markers along the way to mark their way.

But it's getting late, and when it gets dark, even if the mysterious ants don't chase at night, fierce insects and low temperatures will be the killers of these ants who stay away from the nest and expose the wild.

Most of the ants could not survive until sunrise the next day, when the temperature warmed up, and only a few lucky ones found shelter such as stone crevices, tree hollows, and fallen leaves, and were able to survive until the next day and embark on the road home again. [Subject A] is besieged by enemy forces, and their best outcome is to find an ant path to the other nests.

The Bee Flying Knights found the Northern Expeditionary Army Worker Ant Warrior who provided information, and it is not known whether she has returned to the nest now, or whether she has been chased by mysterious ants again.

From the information sent by the scouts, the protagonist found the route to [Target A], at this time, the flying knights could not take off at night, and only by relying on the guidance of the ground scouts, the Divine Envoy King Legion could accurately reach the destination.

However, the thing that worries the protagonist is that the scouts ahead have not found any pheromones left behind by the mysterious ants.

The pheromones of each ant are different and cannot be read from each other, but it is still possible to tell whether the pheromones are native or foreign.

Now, in addition to the very obvious pheromones of the big-headed ants left by the Northern Expeditionary Army, there are also some very faint paver ant pheromones - that is the remains of the long-lasting pheromones left on the ant road when this place was still a pavement ant barbarian country, and there is a family of paving ants in the army of the gods, although the big-headed ant scouts can't read its meaning, but they can distinguish its source.

However, apart from the pheromones left by the big-headed ants and the paver ants, the scouts did not find pheromones of the third race, which means that there were no pheromones left by the mysterious ants in the area.

Don't the mysterious ants need pheromones to command and coordinate the actions of large forces? How is this possible? It is important to know that in addition to antennae communication, pheromones are the most important and widest communication methods between ants.

The protagonist can't imagine how the mysterious ant army should coordinate without relying on pheromones, it is not enough to rely on tentacle communication, tentacle communication is point-to-point communication, although detailed but the scope is too narrow, and the ants do not have a broad-spectrum communication method such as sound media, pheromones, that is, chemical communication, is the only large-scale broad-spectrum communication means.

Mysterious ants can't communicate directly by brain waves, as written in science fiction novels, which is also too fantastical.

The protagonist can only guess that perhaps the pheromones of the mysterious ants are unique, and the scouts can't distinguish them well, confusing them with chemical debris in nature.

Although there are no pheromones of the mysterious ants, relying only on the pheromones left by the Northern Expeditionary Army, the protagonist has obtained a lot of useful information.

The entire legion is also following the pheromone guidance of the Northern Expeditionary Army, and is rapidly approaching [Target A], close to the siege force of the mysterious ants.
