In the stalemate and depression, the ultrasonic focus is activated, and the ultra-high frequency sound waves are not heard by everyone, but they can make people feel its terrifying lethality. The mermaid artillery team's fire point and the rocks under the fire point were hit hard. The sound of the rock breaking and collapsing kept ringing, and the rubble, smoke, dust, and sand flew and exploded in all directions, making the giant squid with multiple suckers with tentacles unsteady on its feet, and in the words of the terrestrial people, it made people roll on their backs. But as long as the damage was not severe, the gunners regained their composure, and immediately went into battle again at the gun emplacement.

The two sides have been attacking back and forth like a tug-of-war, both trying to break down the wall that the other side has built. Maybe such a battle is also watching, or how can it be raining frantically in the sky at the same time? Is it just to cleanse the world of war?

The ultrasonic focusing power of the whale group is quite amazing, the ultrasonic energy is focused on a point, the energy is so great that the rock can be shattered, and the mermaid artillery life form will also be shocked and dizzy, which is extremely hard and terrifying. But whales also have weaknesses, they breathe with their lungs. The limit of the diving time is usually about two hours, and it can't last so long during the battle, so it will definitely take turns to surface in the middle of the way to breathe.

Sure enough, the commanders of Kacheng spotted a whale floating up trying to get out of the water to breathe, so they took steps to intercept the whale.

Although the sea was tumbling with whale waves and wind and rain, the thousands of flying fish who received the battle order did not flinch. They fly over the surface of the sea like birds with their large fins, and drop ice and lightning time-lapse bombs on whales that are outcropping out of the sea. This time-delay ice thunder bomb is designed for the Flying Fish, and only after the Flying Fish is thrown, the mechanism will be activated to detonate to prevent the Flying Fish from harming itself. The diversity of marine life has also contributed to the strategic position of the Flying Fish as a maritime air force.

Dense ice and thunder time-lapse bombs smashed like hail at the whales that were outcropping, and the explosions exploded countless waves that were chaotic and frequent, making the atmosphere on the sea almost boil. The whales, which had been blown up in a daze, found the flying fish and the bombs they brought, and vigorously sprayed a jet of water from the fountain dozens of meters high from the air hole above their heads, trying to drive away the flying fish with the water column like a fly and insect. Many of the Exocets were also shot down by the water after dropping their bombs, but the Exocets' offensive was still ambitious. After the bomb went off, there was damage on both sides. And war is inherently cruel, and who doesn't hate the tragic consequences of war?

The Exocet Air Force became more cautious and nimble after being disturbed by the fountain jets, flying faster and higher to avoid the jets of water spewed out by the whales. Although the whale was blown up left and right, it barely carried the bomb with its stiff head and rough thick skin, and when it encountered the bomb more dense and concentrated drop, it could only escape quickly, otherwise it would be blown up enough.

Both the undersea battlefield and the sea battlefield were fought in darkness, and the temperature of the sea water increased significantly, and the stirred up sand and dust filled the sight. Like an ocean whirlpool that wants to suck all souls into it, tempering the will of all life, and writing another story of blood and tears.

There was a series of rather loud bell-like cries in the water, the sound of a group of whales making a muffled internal conversation. The mermaid artillery and the huge squid who had never retreated from the defensive positions of Kacheng had not yet fully understood what was going on. I saw that the wall put together by the whale re-moved and adjusted, as if at halftime. But in the eyes of the commander of the Kacheng army, the whale's strange behavior is likely to be brewing a new round of attacks, or a new kind of joint release of the ultimate, which is about to be launched.

Seawater is a good conductor of sound wave transmission, and the sounds of the battle of Kacheng directly scared away many marine fish and other life species outside the city. Perhaps life is just a simple escape from danger in the consciousness of these creatures, and being alive is its own hero.

The ultrasonic focus of the whale school stopped, making the defenders of Kacheng a little puzzled, were they about to surrender? It can't be, there should be another plan.

In the headquarters of the defense of Kacheng, Hu Liuxiuji, who commanded the king squid, and Zhuzhu, who commanded the overlord sour squid, had not yet figured out what new tricks the whales would use, but the careful Zhuzhu had a strong premonition that greater danger was about to appear.

Regardless of her own safety, Zhuzhu rushed out of the headquarters and climbed all the way to various fortifications, bypassing heavy rocks and entering the battlefield in person, she needed to see the pattern of the whale formation with her own eyes and find out the battle strategy. At the front end of the battle line, the scene of the movement of the black and oppressive whales came into view.

After the previous war, the whales that emitted ultrasound from the front were mainly sperm whales, beluga whales and killer whales. In the classification of cetaceans, these three types of whales belong to the suborder of toothed whales, and one of the common characteristics is that they can emit powerful ultrasound waves. At this point, the three species retreat to the back, and those that swim to the front are replaced by humpbacks, gray whales, and blue whales.

Zhu Zhu cautiously analyzed the battle situation, recalling a lot of knowledge about whales that the whale pet owner Han Xiaoxiao had told her many years ago. The three types of whales assembled later belong to the suborder of baleen whales among cetaceans. Relatively speaking, they are better at using infrasound, well! The infrasonic energy emitted by a single whale is not large enough to cause infrasonic damage, although infrasonic waves can sometimes travel more than 800 kilometers away. In order to make infrasound more lethal, it is necessary to control all baleen whales that can be controlled at the same time and at the same frequency to send joint infrasound pulses at the same time......

Oh my God, how many mermaid companions can be knocked unconscious and killed at the same time by such an infrasound matrix pulse? What a powerful and terrifying beast trainer must Akentero, who controls the whale colony?

Don't care about your own safety, one second later will be one more point, and you must defeat the opponent before the opponent completes the formation. Zhuzhu rushed to the side of the largest battery in the position and shouted:

"Hurry up and attack! Whales want to use infrasound matrix pulses! ”

When the artillerymen heard the news, they immediately opened fire, and waves of shockwaves rained down on the wall where the whales were about to finish. The whale that was hit was in a short period of time, causing holes to crack one hole after another in the wall, but the whale that was controlled was not a fuel-efficient lamp, showing an unusually arrogant strength. One whale was shaken open and the other was reinforced, making the artillery of Kacheng very hard.

When the Whale Wall trembled and the dangerous formation in the furious sea was completed with astonishing brute force, the partners of the Carcity Mermaid Artillery Team, the Overlord Squid and the King Squid, let out a low wail, and then the mermaid gunners felt a sense of fear that made their whole body unwell soaked through their bodies. It was a painful feeling that almost all the internal organs in the body were struck and the body no longer obeyed, almost suffocating......

It turns out that, as Zhu Zhu deduced, after being manipulated by Acantero, the whale, who was also a little afraid of infrasound, is now using infrasound as a weapon instead of being afraid of infrasound. But in theory, this is also a suicidal attack for whales, and Acantero is really hard-hearted and ruthless.

The offensive of the Infrasound Matrix Pulse had begun, and the attacks of the giant squid and gunners in Kacheng had almost completely collapsed and stopped. Among the city guards, dizziness, madness, and many of the symptoms spread rapidly.

"Brave soldiers, we must not give up our efforts in order to protect our homes and loved ones who need protection!"

Zhu Zhu climbed up to the higher gun emplacement, shouting to the gunners, and although her mind was already buzzing and dizzy, she still restrained herself from keeping her balance and set about to fire herself. But what I saw in my eyes turned out to be a picture of the world spinning, as if my head and body did not look like my own. Your own body is rejecting your own conscious thoughts.

The infrasound matrix formed by the combination of infrasound waves and the same frequency at the same time is so powerful, just like the Soul Snatcher played by the Grim Reaper impacting the guardian warriors of Card City.

The sound of an ice mine exploding behind the whale wall was heard, a signal from a group of dolphins and flying fish casting ice mines from the flanks and behind the whales to disturb each other. The shock wave from the explosion caused a brief interruption in the whale's infrasound matrix, and also caused a commotion in the whale group.
