The camera comes to a bleak and desolate high-level world city-

As the 13th World Combat Series approaches, there are few pedestrians on the streets, few speeding cars in the sky, and the buildings on both sides are ten rooms and nine empty.

Everywhere there are ruins left behind by strife and killing.

The wreckage of humans and robocops is everywhere.

I walked down this desolate deserted street.

Where dreams begin, and where dreams end.

When humanity started a foundation on the land of this planet called Earth.

Perhaps I never thought that one day, these Danying carved trees, layers and platforms, carved fences and jade masonry, Qionglou Yuyu, Feige Liudan, Hongtu Huaguo, painting Dong Feiyong's bustling city will be like today's rafter tiles, full of desolation.

The history of the explosion of human science and technology in Huawu Autumn Market.

Blood-soaked battle for the qualification medal.

Let the "Yue Buqun" who are in the rivers and lakes and have their hearts hanging on Wei Que unscrupulous means, their six relatives do not recognize, they attack wolves, and exterminate human nature, and embark on the killing battlefield of the last days at the end of the road.

The person who worries me the most now is Murong Hanmei, I don't know why she didn't listen to my advice and opened the door to go out without permission.

I only know that she is now missing.

She only has an energy level of 28, and in this chaotic post-apocalyptic battlefield, she is like a mayfly dying in the twilight of life, and she may lose her fragrance and bury her incense at any time.

Just as I was lost in thought.

Suddenly, the control background alerted me to a high-energy response ahead.

I saw a large group of robot soldiers walking in front of me.

At the forefront of this robot force is a gloomy-looking woman.

I hurried to take an arrow step and ducked behind a large pile of rubble next to me.

Suddenly, several figures flashed through the ruined buildings nearby, and in an instant they came to the front of the machine troops, blocking their path.

I counted five people in the way.

All five of them were dressed in military camouflage uniforms, wearing all-encompassing metal helmets, invisible appearances, covering metal armor on important parts of their bodies, and wearing a variety of unique weapons.

Judging from the body shape, it should be three men and two women.

One of them was a man of male form, whose helmet split from the top of his head into four pieces, quickly tucked into the armor that covered his shoulders and chest.

I saw that he was wearing a small round lens like a monitor in front of his right eye.

"If you don't want to die, get out of the way! I'm in a hurry! The woman leading the machine unit said gloomily, not wanting to dwell too much, as if there was some important task on her shoulders.

"Oh, a woman who looks quite peugeot is so fierce! Let me introduce myself, I'm the captain "Netmund", I'm a mercenary, and these are my teammates. The man who put away his helmet said.

"Mercenaries? Who are your employers? The woman asked.

"I can't disclose the information of my employer, this is the rule of our business, you are the commander of the 1st Mobile Unit of the "Arnold Military Region", "Cold Butterfly", right?"

"No more nonsense! Just five mercenaries dare to stop our Star Sea Mobile Clan! I think you're tired of life! The woman said coldly.

"Oh, what a woman you can't talk to! By the way, have you ever heard of "Grim Reaper"? Netmund asked.

Hearing this terrible nickname, Leng Xuedie was startled and said: "The famous mercenary known as the "No. 1 Killer in the High-level World": "Death Nether", of course I have heard of it! ”

"Tell you a secret......" Netmund's helmet suddenly rose rapidly, enveloping his entire head, "We are the Grim Reaper'!" ”

Hiding behind the broken wall not far away, I was shocked and felt unbelievable, the "Grim Reaper" who had been chasing me and Honghe in the shadows, but had never seen their appearance, was not a person, but a team of mercenaries!

As soon as Netmund's words fell, the five mercenaries suddenly disappeared.

"Grim Reaper! It turned out that "stealth technology" was used, how could I not have thought of it back then! I cursed to myself.

I saw the Grim Reaper, Netherworld, mercenary killer squad, and machine troops using stealth technology fighting.

"Activate the infrared body sensor! Determine the distribution of thermal targets for precise strikes! Cold-hearted Butterfly calmly ordered the machine troops.

With the help of infrared body sensors, the machine unit immediately fired at the Reaper Netherworld squad.

This caught the Reaper Netherworld team a little off guard, and although there were no casualties, they dodged very poorly.

Although Leng Xudie is a woman, she is the commander of the First Mobile Unit of the "Arnold Military Region" after all, and has rich experience in combat, and her command and performance on the battlefield are stable and spicy.

"All of them spread out! Keep your distance! Activate the anti-IR gear! Captain Netmund hastened to order.

With the help of anti-infrared equipment, the machine unit lost its precise location of the members of the Reaper's Nether Squad.

The Grim Reaper's Netherworld begins to display its terrifying assassination abilities.

Many of the robot soldiers have been destroyed by the strange but powerful weapons of the Reaper Nethertro, and their numbers are dwindling.

The Frosty Butterfly moves quickly around the field, dodging attacks and looking for opportunities to counterattack.

The Marshal of the Arnold Military Region, Huangfu Haolei, is the top three members of the Xinghai Council in terms of combat power, and Leng Sha Butterfly can be said to be his most trusted right-hand man, and under the training of Huang Fu Hao Lei, Leng Sha Die's strength should not be underestimated.

"What a misfortune for you to meet me! Grim Reaper, it looks like your employer is going to be disappointed! As he spoke, Leng Sha Butterfly took out something strangely shaped: "My medium doesn't mind your human stealth technology!" ”

"Ultrasound Butterfly Dance!" As soon as the words fell, under the guidance of high energy, the medium in Leng Sha Die's hand suddenly trembled, accompanied by extremely violent tremors, emitting bursts of ultrasound.

Ultrasound (sound above 20,000 Hz) and infrasound (sound below 20 Hz) are inaudible to the human ear.

The harm of ultra (sub)sound waves to the human body depends on the energy output rate, and at high energy they can be used as a weapon to kill.

When ultrasound waves propagate through living organisms, they cause changes in the function and structure of organisms through the interaction between tissues, which is called the biological effect of ultrasound.

The mechanisms that produce "biological effects" are "thermal effects" and "cavitation effects"

The thermal effect refers to the fact that part of the energy is absorbed by biological tissues and converted into heat energy during the propagation of ultrasonic waves, which increases the temperature of tissues.

The cavitation effect refers to the interaction between ultrasonic waves and the air nucleus or microbubbles in the tissue during propagation, causing it to burst suddenly, generating huge instantaneous pressure and changing the internal structure of the tissue.

The frequency of infrasound waves is similar to the natural frequency of human organs, the natural frequency of human organs is 3~17 Hz, the natural frequency of the head is 8~12 Hz, and the natural frequency of abdominal organs is 4~6 Hz.

Therefore, when infrasound waves act on the human body, the human organs are prone to resonance.

If the power of high-energy infrasonic waves is very strong, when the human body is affected by them, it can even cause vomiting, difficulty breathing, muscle spasms, nervous confusion, loss of consciousness, rupture of internal blood vessels, heart paralysis, etc.

Ultra (sub)sonic weapons are new concept weapons that use these principles to affect and kill the human body, also known as "silent killers"

Back in the field, the terrifying team of "Death Nether", known as the "No. 1 killer in the high-level world", with the help of "stealth technology", once killed people in the high-level world.

But this time, under the effect of high-energy ultrasound, the Grim Reaper Netherworld team suffered an unprecedented blow.
