Chapter 1700: The rat tide is back!

No, the underground aura transmission pipelines in Longcheng have undergone special explosion-proof treatment. Even if the aura leaks and catches fire, there will be few serial explosions.
Otherwise, during the monster war, as long as there are a few monsters that are not afraid of death, get into the ground and bite off the pipes, they can blow up several densely populated blocks.
That is how the matter?
Meng Chao had an ominous premonition.
Focusing on the soles of the feet, through the soles of the reinforced boots, I keenly sensed the faint but strange vibrations coming from the ground.
It was as if something, something like a tide, was surging up from the depths of the earth.
"It stinks!"
Meng Chao narrowed his eyes, took a deep breath, and smelled a strong and familiar scent from the joints of the manhole covers on both sides of the street.
This is... the breath of a monster!
"not good!"
Meng Chao's child hole suddenly shrank.
At the same time, within a radius of one kilometer, hundreds of manhole covers on the streets and alleys vibrated violently at the same time, making a sound of "crash, crash".
Before the ordinary citizens standing around the manhole covers could react, these manhole covers were impacted by strange forces originating from the ground, bounced high, and fell heavily from the air.
Several manhole covers smashed the roofs of nearby vehicles into pits, and smashed the windows at the same time, making a sharp noise.
There were also several manhole covers that almost fell on ordinary citizens, causing everyone to jump up in exclamation.
Before ordinary citizens could react, black "fountains" rushed out from hundreds of manholes.
"Squeak squeak!"
The black "fountain" made a piercing cry and split into torrents, rushing towards the densest crowd.
The crowd that was caught off guard was immediately torn apart by the black torrent, and many people screamed.
"Yes, it's a ferocious rat!"
"Rat tide, rat tide broke out!"
Fierce-toothed rats, rodent monsters, in the monster battle power pyramid, they were originally only used to be at the bottom, and they were not in the mainstream.
However, relying on the powerful reproductive ability of rat monsters, a litter can give birth to dozens of cubs, and the survival rate is extremely high. It can have basic destructive power in three months, and can reproduce again in six months. geometric progression.
Coupled with the unique ability of rodents to burrow, burrow and bite, it is enough to destroy everything that humans have carefully buried in the ground, such as underground optical cables, underground aura transmission pipes, and a large number of facilities attached to underground transportation tracks.
Therefore, the rat tide formed by thousands of rat-like monsters is definitely one of the most troublesome threats to mankind during the monster war.
From a certain level, the threat of the rat tide is even greater than the threat of the doomsday beast 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 Longcheng.
Once the doomsday beast shows signs of moving towards the main city of Longcheng, all the train cannons in Longcheng will turn around at the same time and launch indiscriminate bombardment at it.
All the powerhouses in the realm of the gods will also be on guard, guaranteeing that the doomsday beasts who do not know whether to live or die will fall into the ocean of the power of the realm of gods.
But the rat tide is different.
Because of the burrowing ability and stealth of rat monsters.
Rat tides often erupt directly from the ground in the main urban area or even in the downtown area.
Humans can certainly fight off the rat tide.
But it is difficult to guarantee that in the process of fighting the rat tide, it will not cause the slightest collateral damage to the homeland that has been built so hard.
This is what the so-called "rat-proof weapon" means.
Moreover, the rat tide is easy to extinguish, but it is not easy to completely eliminate it. As long as one tenth of the rat monsters escape back to the depths of the ground, and give them a certain amount of food and time, they will be able to revive and make a comeback.
Even the powerhouses in the divine realm have no good way to face the rat tide.
Even if the powerhouse in the divine realm has the ability to penetrate the sky and the earth, he can't dig three feet in the ground in the whole city, turn the downtown area upside down, and dig out all the mouse holes hidden deep in the ground, right?
Therefore, compared with the doomsday beasts with fierce flames and majesty, the rat monsters are inconspicuous.
But everyone agrees that the threat of the rat tide is far greater than that of any other kind of beast tide!
Fortunately, with the end of the monster war, there has been no rat tide in Longcheng for a long time.
In the large-scale renovation of the old city in the past year, many urban areas that were originally disorganized have indeed achieved the literal meaning of "digging three feet into the ground".
Not only have the dead corners where snakes, insects, rodents and ants are easy to breed are cleaned up, but also drugs that can eliminate rodent infestations are regularly placed in the depths of the ground.
Relying on the underground transportation rail line, a strict underground monitoring and early warning system has been set up to ensure that when a large number of insects and rodent monsters are ready to assemble in the depths of the ground, humans can detect in advance, and the threat of rat tides can be detected in advance. strangled in infancy.
In addition, many super enterprises have also developed various small automated rune machines suitable for underground operations.
For example, Leiyun Technology has developed a small automatic rune machine, equipped with the nervous system of rat monsters, which can simulate all the 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, and killing rodents with rats".
Under such protection, everyone thought that the rat tide was a thing of the past, a fragmented dream demon.
Unexpectedly, today, the rat tide broke out again.
It is still the most densely populated downtown area in Longcheng, where vehicles are all congested.
Still at this juncture!
"how is this possible!"
"Where did so many fierce-toothed mice come from?"
"Why doesn't the underground rodent control device work? What about the early warning system? It will take at least several days for such a large-scale rat wave to gather together. Why didn't the early warning system detect it in advance?"
People were shocked and angry.
However, the monster war is over. After all, it has only been a year. Many Longcheng people still have strong fighting instincts on their muscle fibers and nerve endings.
And the individual combat power of rat monsters is far from being powerful.
Even if the academic performance is slightly 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 tide, many ordinary citizens drew their fists.
It just so happened that there were many members of the Blue Alliance wearing blue cuffs in the crowd, and they did not hesitate to come forward.
Including the elite soldiers of various law enforcement agencies, are also rushing towards this area.
Accompanied by many extraordinary people, the magnetic field of life was stirred to the limit, spewing out bundles of spiritual flames visible to the naked eye.
The ordinary citizens who were a little flustered just now calmed down after being raided by the rat tide.
