This day is a historic day for the Big-Headed Ant Kingdom, although there is no history book in the ant world, but in the future, the word-of-mouth information package species, about the glorious history of the Big-headed Ant Kingdom, will inevitably remember this day.

On this day, the weather was sunny and it was a good day.

Or rather, the weather has been going on for a few weeks, with very little clouds in the sky, not very strong winds, and the sun is hot and fierce, which is the weather that plants and cold-blooded animals like.

Although there was a slight drought on the surface due to the long period of no rainfall, it was very good weather for the ants.

Without the deadly threat of rain and muddy obstructions, sunlight can also provide an additional valuable source of heat for ants on the move, which they love for the temperature and humidity.

From early in the morning, in the main nest of the big-headed ant kingdom, swarms of ants poured out from the entrance of the main passage.

The groups were arranged in stout marching columns, which stretched out over the wilderness and eventually grew to a full half a meter wide, and the ranks advanced as the follow-up troops continued to pour out of the main nest.

These are the main nest and the troops that converged to the main nest from the various secondary nests, and the 150,000 Northern Expeditionary Army officially started today.

If you look at it from the air, you can see such a spectacular scene:

The long procession was clearly visible even in the air, like the black snake winding on the ground.

Directly in front of the team, countless scouts spread out like branches and leaves growing from the trunk of a tree, constantly extending the eyes of the army in front of the team, and maintaining constant contact with the large army.

The front end of the line is moving forward, but the back end is still pouring out as if there is no end. The 150,000-strong army will spread out a marching column tens of meters long on the ground.

The power of this swarm was terrifying, and directly below the marching procession, thousands of ants gathered together, and the thick body odor was diffused by the wind, and the insects that smelled this breath, whether they were herbivorous insects or insects that were good at hunting, were all terrified and desperately tried to escape the area.

Some flying insects try to flee into the distance, some bury themselves in the soil, and snails and others retract into their shells.

These were all lucky, and the insects that stood in front of the march route of the Northern Expeditionary Army were almost invariably discovered by the scouts who were spreading around.

Scouts will not be polite to these potential rations, and even one scout will dare to attack the most ferocious centipedes, scorpions, or mantis among the insects.

Because she knows that she has her own partners behind her. As long as these prey are delayed for half a moment, countless ant warriors will come and surround it and bite it to death.

Maybe some fierce insects dare to sneak up on hunting lone ants, but in the face of this condensed force that is enough to destroy the world, the insects will understand who is the overlord of this world.

As the army advanced, it swept away the prey in its path. Although this harvest is only a drop in the bucket for the huge size of the Northern Expeditionary Army, fresh meat can still boost everyone's morale.

The marching route of the Northern Expeditionary Army is to follow the ant path between the main nest and the secondary nest, and between the secondary nest and the secondary nest, chasing the signal elements on the ant path, and approaching the "Waterfront City" step by step.

These paths pass under the bushes and weeds, and although they are not straight and slightly winding, they are basically on solid ground, and even if there are occasional boulders or mud pits blocking the way, there are always small pathways that can accommodate the ants to pass through, eliminating the trouble of constantly detouring and climbing, and the large number of stale plants.

The network of ants that communicate the entire kingdom of the Big-headed Ant is not a natural formation, but is developed and regularly maintained by the ants themselves.

Each sub-nest will send a team to the main nest twice a year, mainly to escort the wedding team, as well as transport materials, plus temporary deployment, over the years, it has found a relatively suitable smooth road.

Each team will clear new obstacles along the way, and if they can't get rid of them, they will find a new way around them. In addition to clearing the road, the males who pass through the antway also leave a unique long-lasting pheromone to guide their directions.

These pheromones are not ordinary pheromones left by the worker ants and soldiers, and ordinary pheromones tend to evaporate within a few days. These pheromones left by past males are scattered on rocks and other landmarks that are not easy to move, and although the smell is very light, they can be retained for eight or nine months.

The ant road is less than the width of a person's finger, and it is enough to accommodate the ant team on weekdays, but at this moment, it cannot accommodate the Northern Expeditionary Army team that is more than half a meter wide.

Therefore, most of the Northern Expeditionary Army still operated on both sides of the ant road. Sometimes when faced with huge shrubs, trees, and rocks, the army has to climb over if they can't get around it.

For a while, there were traces of crawling ants all over the mountains, and if you take this scene and put it on the documentary channel, it will really have the style of marching ants that devour everything.

The speed of the march of the huge army is certainly not comparable to that of the small and flexible troops, and a secondary nest not far from the main nest, which could have been reached in half a day, took the Northern Expeditionary Army more than half a day to arrive in the afternoon.

The distribution of secondary nests in the entire big-headed ant kingdom is very regular, and between any two nests, it is basically the distance for ants to crawl for half a day. This allows the ants to reach two nests throughout the day and spend the night in the last one.

The Northern Expeditionary Army did not stay in this lair, it was still early, and the enthusiasm of the Northern Expedition and the lack of military rations urged the army to continue on its way.

But they couldn't get to the next nest before dark, and although the daylight was long now, the army was slow.

Finally, the Northern Expeditionary Army ushered in the sunset in an arbor forest.

If a small group of troops dares to operate at night, it is convenient for them to communicate and command each other. With such a large force, they almost lost the ability to act in unison at night, so they had to camp on the spot.

Ants are relatively vulnerable at night on the ground without nest protection.

However, as long as the temporary campsite is carefully constructed, no insect will dare to risk attacking an ant colony of this size, except for the hungry red-eyed.

The Northern Expeditionary Army surrounded the trunks of several tall trees, and the bark of the trunks within one meter above the ground was tightly covered. The ground between the trees was also covered with ants, and only in the outermost part was a tightly connected arc of defense.

The males are protected inside, hiding under the bark of trees, in tree hollows, or in the safety of the ground. Worker and soldier ants take on the responsibility of protection.
