Oh My God! Earthlings are Insane!

No, Dragon City's underground spiritual energy pipelines have all undergone special explosion-proof treatment. Even if the spiritual energy leaks and catches fire, serial explosions rarely occur.

Otherwise, during the monster war, as long as a few fearless monsters burrowed into the ground and bit off the pipes, they would be able to blow up several densely populated neighborhoods.

That is how the matter?

Meng Chao had an ominous premonition.

Concentrating on the soles of the feet, through the soles of the reinforced combat boots, he keenly sensed the weak but strange vibrations coming from the ground.

It was as if something, something like a tide, was surging up from the depths of the ground.

"It stinks!"

Meng Chao narrowed his eyes, took a deep breath, and smelled a strong and familiar smell from the seams of the manhole covers distributed on both sides of the street.

This is... the breath of a monster!

"not good!"

Meng Chao's pupils suddenly shrank.

At the same time, within a radius of one kilometer, hundreds of inspection manhole covers on the streets and alleys vibrated violently at the same time, making a "crash, clatter" sound.

Before the ordinary citizens standing around the manhole covers could react, these manhole covers were hit by a strange force from the ground, bounced high and fell heavily from mid-air.

Several manhole covers made pits on the roofs of nearby vehicles, and smashed the windows at the same time, making sharp noises.

There were also several inspection manhole covers that almost fell on ordinary citizens, causing everyone to jump up in exclamation.

Before ordinary citizens could react, streams of black "fountains" rushed out of hundreds of inspection wells.

"Squeak creak!"

The black "fountain" let out a piercing cry, and split into torrents, rushing towards the densest crowd.

The crowd who were caught off guard were immediately torn apart by the black torrent, and many people screamed.

"Yes, it's the Vicious Tooth Rat!"

"Rat tide, rat tide broke out!"

Fierce-toothed rats, rodent monsters, were originally only used to be at the bottom of the pyramid of monster combat power.

However, relying on the strong reproductive ability of rat monsters, a litter can give birth to dozens of cubs, the survival rate is extremely high, they can have basic destructive power in three months, and they can breed again in six months. geometric progression.

Coupled with the unique ability of rodents to drill, burrow and bite, it is enough to destroy everything that humans have carefully buried underground, such as underground optical cables, underground spiritual energy transmission pipelines, and a large number of facilities attached to underground transportation tracks.

Therefore, the rat swarm formed by the gathering of tens of thousands of rat monsters is definitely one of the most troublesome threats to mankind during the monster war.

From a certain level, the threat of the rat swarm was even greater than the threat of doomsday beasts like the diamond nine-headed dragon.

Because of the huge size of the doomsday beast, the target is obvious, and it will be discovered by humans if it is hundreds of kilometers away from Dragon City.

Once the doomsday beast shows signs of heading towards the main city of Dragon City, all the train guns in Dragon City will turn around at the same time and bombard it indiscriminately.

All the powerhouses in the divine realm will also stand ready to ensure that the doomsday beasts, who do not know whether to live or die, will be plunged into the vast ocean of the power of the divine realm.

But Rat Tide is different.

Because of the burrowing ability and stealth of rat monsters.

Rat swarms often erupt directly from the underground of the main urban area or even the downtown area.

Humans can certainly fight rat infestation.

However, it is difficult to guarantee that in the process of eradicating the rat tide, the homeland that he has worked so hard to build will not be caused any collateral damage.

This is the reason for the so-called "throwing the mouse to avoid the device".

Moreover, the rat tide is easy to extinguish, but it is not easy to completely eradicate it. As long as one tenth of the rat monsters escape to the depths of the ground, and they are given a certain amount of food and time, they will be able to revive and make a comeback.

Even those who are strong in the divine realm have no good way to deal with the rat tide.

Even if a strong man in the divine realm has the power to penetrate the sky and the earth, he can't dig three feet within the entire city, turn the downtown area upside down, and dig out all the mouse holes hidden deep in the ground, right?

Therefore, compared with the fierce and majestic doomsday beasts, rat monsters are inconspicuous.

But everyone agrees that the threat of rat swarms is far greater than any other kind of animal swarms!

Fortunately, with the end of the monster war, there has been no rat wave in Dragon City for a long time.

And in the large-scale renovation of old cities in the past year, many originally disorganized urban areas have indeed achieved the literal meaning of "digging three feet into the ground".

Not only clean up the hygienic dead corners that are easy to breed snakes, insects, rats and ants, but also regularly place drugs that can eliminate rodents deep in the ground.

Relying on the underground transportation track lines, a strict underground monitoring and early warning system has been set up to ensure that when a large number of insects and rat monsters are preparing to gather deep underground, humans can detect them in advance and eliminate the threat of rat tides. strangled in infancy.

In addition, many super companies have also developed various small automated rune machines suitable for underground operations.

For example, Leiyun Technology has developed a small automated rune machine, which is equipped with the nervous system of rat monsters, which can simulate all activities of rat monsters, and even exudes the unique breath of rat monsters. Attract them and then kill them, which can be described as "fighting poison with poison, exterminating rats with rats".

With such protection, everyone thought that the rat tide was a thing of the past, a fragmented nightmare.

Unexpectedly, today, the rat wave broke out again.

It is still in the most densely populated downtown area in Dragon City, where all vehicles are congested.

Still, at this juncture!

"How can it be!"

"Where did so many fierce-toothed rats come from?"

"Why doesn't the underground rodent control device work, what about the early warning system? Such a large-scale rat swarm will take at least several days to gather together. Why didn't the early warning system detect it in advance?"

People were shocked and angry.

However, the monster war ended, after all, it was only a short year, and the muscle fibers and nerve endings of many Longcheng people were still entwined with a strong fighting instinct.

And the individual combat power of rat monsters is far from powerful.

Even if the academic performance is a little better, the middle school students who listen carefully in get out of class and practice diligently after class can blow the head of the rat monster alive.

Facing the beast horde, many ordinary citizens pulled out their fists.

Coincidentally, there were still many members of the Azure Alliance wearing blue cuffs in the crowd, who stepped forward without hesitation.

Elite soldiers, including various law enforcement agencies, are also rushing towards this area.

Accompanied by many extraordinary people, the magnetic field of life was agitated to the limit, spewing out bunches of spiritual flames visible to the naked eye.

The ordinary citizens who were a little flustered just now regained their composure after being attacked by the rat wave.
