Fortunately, Rambo is not the kind of male ant who does not learn and does not touch the spring water in the old king's meeting in the original "Qingqiu City", he has participated in many affairs with the protagonist, including the construction of nests and fortresses, and he knows that "ant concrete" takes time to solidify.

The solidification degree of concrete in the human world mainly depends on the solidification speed of the cement in it. The setting time of cement is divided into initial setting and final setting. The time required from the addition of water to the time when the cement slurry begins to lose its plasticity and decrease its fluidity is called the initial setting time. The time required from the time of adding water to the time when the cement slurry completely loses its plasticity and begins to have a certain structural strength is called the final setting time. Generally speaking, the initial setting time of qualified Portland cement shall not be earlier than 45 minutes, and the final setting time shall not be later than 600 minutes.

Although "ant concrete" does not have real cement in it, it contains adhesive components such as ant glue and ant droppings, which is more similar to 502 glue, and its solidification speed is faster. In addition, the engineering volume of ants is generally small, and the oxidation and solidification efficiency is also better.

Generally speaking, within two hours, the "ant concrete" can be completely solidified and functional, but within an hour its solidification is not enough to resist violent destruction.

Rambotu immediately issued an order, using the smell and friction sound to inform the troops near him to step up the attack on the main passage, and to open the main passage at any cost, so that the enemy could not use "ant concrete" to build a new line of defense and delay time.

Due to the complex environment of the underground battlefield, Rambo could only notify the troops and reserves around him at first, and he could only count on the heralds to deliver orders in time for the troops in the distance.

In an hour, whether this sub-nest can be completely conquered today depends on this hour.

- I'm the dividing line -

While the rolling army is fighting fiercely to conquer the barrier sub-nest of the "real main nest" as scheduled, the protagonist is in his main nest "Qingqiu City", thinking about the meaning of the information he has just obtained.

Just today, after he got the information from the flying knights from two places, one south and one north.

Press the south side and don't mention it, let's talk about the intelligence from the north first.

The Northern Expeditionary Army is attacking the southern branch of the Paving Ant Barbarian Nation, which is the news that the protagonist has learned before.

After a long time after the Northern Expeditionary Army, which "connived" at the faction of the Old King's Council of the Big-Headed Ant Kingdom, wreaked havoc in the south, in the face of the attack on the Split Nest, the Paving Ant Barbarian finally gathered a small army to provide support.

Even this small army is inseparable from the Northern Expeditionary Army. After all, the replenishment of the forces of the Northern Expeditionary Army was slow - when crossing the Great River, this force did not carry the queen ant.

At that time, the meeting of the kings considered that it was not safe for the Northern Expeditionary Army to carry the queen, and that the precious queen might be damaged in winter.

If it weren't for the fact that Da Rong took the "bridgehead" to join the Northern Expeditionary Army, and there happened to be an ant queen in the "bridgehead", this army could only lack the replenishment of newborn ants with the passage of time, and just die little by little.

From this point of view, Da Rong is the savior of the Northern Expeditionary Army and even the entire Dawang Conference faction, but this savior was quickly sold.

However, only one queen ant is not enough to maintain the normal replenishment of an army and a kingdom, not to mention the heavy casualties of the battle, that is, daily hunting and gathering will lose a lot of ants, and the queen ant needs to constantly lay eggs to maintain the balance of the ant population.

The Northern Expeditionary Army can only rely on the only queen, and even if this queen is given the most adequate food supply to produce new queens, they will only be able to harvest a new batch of queens this year due to the principle of the wedding flight ceremony adhered to by the old King's Council faction.

In the case of insufficient number of queens, the Northern Expeditionary Army's replenishment rate will be much slower than that of their opponents, resulting in an inability to fight a war of attrition.

If it weren't for the fact that their opponent, the Paving Ant Barbarian Country, who had a large number of troops and national strength involved in something, would have been able to drink hatred early even if the Northern Expeditionary Army had innovated its tactics under the influence of the Divine Envoy King.

The Northern Expeditionary Army has been fighting for about half a month before the southern branch of the Paving Ant Barbarian Country, and the two sides have been fighting back and forth, and no one can help anyone.

And just when the war was stalemate, the Paving Ant Barbarian Kingdom suddenly withdrew its reinforcements, and the southern nest was then occupied by the exhausted Northern Expeditionary Army.

At this time, the Northern Expeditionary Army had lost more than half of its elite troops and was unable to continue to expand. They moved the King's Council and the Queen Ant from the "bridgehead" to the southern nest of the former Paved Ant Barbarians, where they established their rule and served as the core of the territory.

The current Northern Expeditionary Army already has a territory of about twenty sub-nests, although there are not many ant mouths, but it only takes a year or two for them to consolidate their rule and restore the strength and glory of the old King's Conference faction to a certain extent.

Anyway, the Northern Expeditionary Army is powerless to threaten itself across the river, so he can only "look at the river and sigh", what the protagonist is really curious about and has always wanted to figure out is why the paving ant barbarian country suddenly "withered" this year.

You know, before last winter, the Paving Ant Barbarian Army still had the existence of the Northern Expeditionary Army, and even the protagonist fought against this army in winter.

However, last winter, the Paving Ant Barbarian Army did not regain the lost territory on the north bank of the Great River, nor did it adhere to the tradition of southward invasion that has been going on for decades, which is extremely abnormal. Now, they have even given up on the southern nest, and reinforcements have withdrawn.

You must know that according to the information provided by the Floating Leaf King, the Paving Ant Barbarian has one main nest and four sub-nests, and giving up one sub-nest basically means giving up one-fifth of the country's domination.

There must be something big going on in the country.

So, a team of flying knights is ordered by the protagonist to set off north for a long reconnaissance after being fully prepared. After paying a lot of losses, this Flying Knight reconnaissance team finally brought back an important piece of information that answered the protagonist's long-standing doubts.

An ant force that the protagonist has not been in contact with before is attacking the Paving Ant Barbarian Country, and has approached the main nest of the Paving Ant Barbarian Country.

These ants are huge, and there's no exaggeration in the size of these ants.

In the big-headed ant race, the worker ant is generally 3mm long, the soldier ant is 4.5mm long, and the worker ant of the paving ant is generally about 3mm long.

According to the reconnaissance of the flying knight, these ants that invaded the paving ant barbarian country have no distinction between worker ants and soldier ants like paving ants, and all the professional ants have a body length of more than 10mm, and this body even exceeds the body of the male ant and queen ant of the big-headed ant and paving ant.

In contrast, if the size of the worker ants of the big-headed ant race is a small car, and the large-headed ant soldier ant is an SUV, then the ordinary warriors of this kind of ant are the size of a giant on a bus.

What is this sudden ant race? How does it seem that the overlord paving ant on the north bank of the river is about to be wiped out!
