Hearing this news, Lu Zheng's expression was stunned for a moment, and he asked in a deep voice, "When did it happen?"

Liu Ming waved his pliers anxiously and said, "Your Majesty, the minister also just learned about it from the mouth of the whale east. Now, Captain Whale Lei has rushed to it in person. Captain Whale Dong was waiting at the gate of the palace. ”

Tang Scarlet's expression was also full of surprise, and he frowned: "Could it be that there are any strong enemies in this sea?"

"Let's go, go out and have a look. After the surprise, Lu Zheng's face became gloomy, his eyes showed a bit of fierceness and murderous aura, and he hurried to the outside of the palace with Tang Scarlet.

As soon as he left the palace gate, Whale Dong hurried to Lu Zheng's front and said anxiously: "Your Majesty, Captain Whale Mountain, who was patrolling outside, has completely lost contact. ”

Said as he walked. ”

The golden light escaped from the spot, and Lu Zheng turned into a golden dragon and rushed to the place where the incident occurred. Whale Dong, who was accompanying him, slowly narrated the ins and outs of the matter.

Captain Whale Hill is the youngest whale in the Giant God Guard, and is the heir of Whale West. Since Lu Zheng arranged the task of patrolling the sea of the Giant God Guard, he was sent by Captain Whale Lei to the sea area east of the Dragon Palace, and followed his father to carry out the patrol mission.

It has been safe and sound for half a month, and today Lu Zheng returned to the palace, and Whale West rushed back to greet him, so he handed over the task of patrolling the sea to Whale Mountain and let it go alone. After the chaste was completed, Whale West left the Dragon Palace, ready to join Whale Mountain.

But after Whale West arrived, he was surprised to find that no matter how he called, he couldn't get an echo from Whale Mountain. He didn't take it seriously at first, he just thought it was Whale Mountain and swam to other seas. When he finished patrolling according to the established route, he couldn't feel the echo of Whale Mountain all the way, and he felt that something was wrong.

The whale's ultrasonic positioning ability is outstanding, and after being ignited by Lu Zheng, it has been greatly strengthened. In the waters within a radius of 100 miles, you know the terrain, ships, and fish in the palm of your hand. There is also free communication between the same kind. Although Whale Mountain is young and playful, its positioning ability is not weak, and it is impossible to lose contact so inexplicably, and there is a chance that something has happened.

After listening to Whale Dong's narration, Lu Zheng had an ominous premonition in his heart.

Tang Feili frowned and said: "This is too coincidental, if you don't come sooner or later, Your Majesty has just returned to the palace, and you have caught up." ”

Lu Zheng snorted coldly and said: "It's not like an accidental incident, and it's probably not a temporary idea, but a long-planned idea." Captain Whale West is strong. rushed back to meet the driver, and Whale Mountain was singled. Perhaps it was this opportunity they were waiting for, so they suddenly attacked Whale Mountain. ”

Lu Zheng's inference is reasonable, otherwise it would not be such a coincidence.

The area of the incident is east of the East China Sea Trough, which crosses the strait between Toei Kyushu and the Okinawa Islands, and reaches the Philippine Sea, close to the North Pacific border. This sea area is the exclusive economic zone claimed by Dongying and belongs to Dongying's sphere of influence.

About twenty minutes later. Lu Zheng, Tang Scarlet, and Whale Dong met Captain Whale Lei, who arrived in advance.

"Your Majesty. Whale Lei's voice was a little heavy, and he said, "Captain Hum and Captain Whale West have searched the sea area for nearly a thousand miles, but they have not found any trace of Whale Mountain. Dereliction of duty has disappointed His Majesty, and he is willing to be punished. ”

"Didn't find it?" Lu Zheng asked, "When Liu Ming told me." Didn't you say that the whale mountain was poisoned and sank to the bottom of the sea?"

"It's not Captain Whale Mountain. Whale Lei said abruptly: "It was just a passing whale shark, similar in size to Whale Mountain, I don't know what attack it received." Seven orifices bled to death and sank to the bottom of the sea. ”

"Lead the way. ”

"Yes. ”

In a sea basin, Lu Zheng saw the dead whale shark. The death was tragic, the eyeballs burst open, and scarlet blood spread out of the eye sockets, staining the sea area red for hundreds of meters.

Other than that, it has no visible wounds on its body and no toxins in its body. Lu Zheng surrounded the whale shark for a long time, but he never found the reason for its death.

It's weird.

The whale shark's mouth, esophagus, and stomach were even stuffed with undigested fish and shrimp, and it looked like it was eating, when it was suddenly hit by a strong impact of some kind of force, which instantly exploded his brain.

With the whale shark as the center, he used the magic to pass through the surrounding sea area, and did not find any traces left by the magic power.

Soon, Lu Zheng noticed something unusual in a trench.

The trench is lined with several large reefs of hundreds of meters, and it looks no different from other places. However, there are tens of thousands of fish and shrimp carcasses floating in the reef group, and many small fish have their heads bursting open, which is very similar to the death of whale sharks when you look closely.

In addition, there was a large pool of dead fish floating on the surface of the sea above the reefs, and the blood stained the entire sea surface red.

The reef is supposed to be the site of the death of the whale shark, whose carcass was washed away by ocean currents.

"Where's Whale West?"

"Captain Whale West is worried about the safety of Whale Mountain, and has already set out to search the sea farther ahead. ”

"You go and join Whale West now, calm him down, and don't take any chances. Lu Zheng was in a heavy mood, and the enlightened whale was very intelligent and emotional. They still look like whales, but they're essentially human.

Whales have a strong sense of family, and family affection is very important to them. As the father of Whale Hill, and his son is missing, he must be in the same mood as all fathers, panicked, sad and desolate.

In this state, if you encounter the enemy, I am afraid it is not a good thing.

"Yes, this is to appease the whale West. ”

After Whale Lei left, Lu Zheng led Tang Scarlet Carp and Whale East to the dead reef group. The sea here is very quiet, a large number of fish and shrimp died tragically, gloomy and lifeless.

Whale Dong looked at the corpses in his eyes, as if they were the reefs of a slaughterhouse, and said sadly: "Vicious, too vicious." Tens of thousands of innocent lives died here like this. ”

Tang Scarlet Carp swam around the reef twice, and the smell of blood was everywhere, and he also felt a wave of anger rise in his heart, and said viciously: "Your Majesty's expectation is good, this is indeed a conspiracy. Their target was Whale Mountain, but these innocent fish and the whale shark must have been affected and innocently implicated. ”

Judging from the scene, the opponent's power is very terrifying, and it is still an indiscriminate attack, and the scope of influence is huge. Lu Zheng suppressed his boiling anger and searched the reef for anything unusual.

The Tang Scarlet Carp and the Whale East also dispersed and surveyed the reef groups.

Half an hour later, Lu Zheng swam to a reef and locked his eyes on the seaweed covering the surface of the reef. Meters of seaweed cascading and swaying with the water make it look ordinary. However, the things in the seaweed bushes did not escape Lu Zheng's eyes.

The steel mass, several meters long, resembled a torpedo, with a deep black livery and almost identical color to the reef, with seaweed entwined around it, and it was impossible to spot without looking closely.

Using the water resistance technique to lift this steel giant out of the seaweed forest, Lu Zheng's eyes gradually became cold.

This thing looks like a torpedo, but it is not the same as a torpedo, there is no warhead in front and no thruster in the back. Instead, it was a black raindrop-shaped bump.

"Your Majesty, there is something strange here. Tang Scarlet Carp came over, and a hundred meters away from here, she also found such a steel giant.

After a while, Whale East also made the same discovery.

The three of them were displayed together, and Whale Dong said angrily: "Your Majesty, isn't this a missile? It must be this thing, the sneak attack on Whale Mountain." ”

"This is not a missile. Lu Zheng slowly shook his head and said, "There are no traces of an explosion here, if I guess correctly......" He paused and looked at Tang Scarlet.

The two said in unison: "Sonar!"

Due to the rapid attenuation of electromagnetic waves in water, they cannot be used as a signal source for detection, but sound waves can be transmitted in water. Sonar is currently the most mainstream seabed detection and underwater surveillance equipment, and its role is very extensive. It can be used to detect, classify, locate and track underwater targets, conduct underwater communication and navigation, and ensure the tactical maneuvering of ships, anti-submarine aircraft and anti-submarine helicopters and the use of underwater weapons.

In addition, sonar technology is widely used in torpedo guidance, mine fuzes, fish detection, offshore oil exploration, ship navigation, underwater operations, hydrographic surveys, and seabed geological and geomorphological surveys.

The ultrasound waves emitted by the sonar have a great impact on the dolphins and whales that are positioned by ultrasound. Medium-frequency sonar can interfere with and destroy the positioning system of whales and dolphins, resulting in hearing loss, loss of sense of direction, and eventually stranding and death.

If the power is high enough, it can even kill the whale directly. Human beings use this principle to deploy high-frequency sonar in the coastal waters of various countries to kill frogmen.

In recent years, people have become aware of the damage that sonar can do to marine ecosystems. At present, the navies of various countries mainly use low-frequency sonar to reduce the noise and ultrasonic energy as much as possible, and reduce the impact on the fish that use ultrasound.

The ins and outs of the matter are clear.

After the Whale Mountain is ignited, the sensory system is more developed, and the ability to sense ultrasound is super strong. But this is also a whale's weakness, if it is subjected to high-intensity ultrasonic noise, it can cause permanent damage to its sensitive organs in an instant, and even head damage, eyeball bursting, and even death.

Viewers who have watched Xingye's new film Mermaid may be very familiar with the 10% intensity sonar ultrasound that shocked Brother Chao out of the bridge.

It's not funny, it's factual. The sonar used for detection is not very powerful. But if the ultra-high-power infrasonic sonar has reached the weapon level, not to mention the feces and urine airflow that shocks people, even the huge whales and sharks will lose half their lives if they don't die.

The tragic situation of the whale shark, the shocking slaughterhouse, Lu Zheng can conclude that these sonars disguised here have been modulated to a super-large intensity of madness.

It was a premeditated ambush, as sonar of this power was very rare, and it was clearly a sonic weapon that was specifically developed and cleverly camouflaged in seaweed. (To be continued.) )
