Chapter 42 Sound Wave
……

"Garuda!"

"Impossible, this must be an illusion!"

Wu Wen widened his eyes and looked at the huge monster in front of him in shock, his heart filled with disbelief.

Garuda is the guardian deity in Buddhist mythology!

How could something like this appear in reality?
I must have fallen into some strange illusion!

Wu Wen immediately concentrated and calmed himself, trying to steady his mind. He activated all five senses and frantically collected information about his surroundings. He also analyzed it quickly in his mind, trying to dispel the illusion before him.

However, no matter how hard Wu Wen tried, the real information he collected told him that this was true! This Garuda really existed!

The appearance of Garuda on the battlefield was undoubtedly a demon to Liu Heita's army defending the city, making them terrified.

But for Li Shimin's Tang army, this was undoubtedly help from the gods, which excited them, boosted their morale, and launched even more fierce attacks.

"Impossible, this can't be true!"

As a staunch atheist, Wu Wen never believes that things in mythology will actually appear in reality.

In his heart, he always firmly believed that the thing before his eyes was absolutely fake, and he must have fallen into some very sophisticated illusion, so sophisticated that he could not break it.

He took out the thirteen silver needles he carried with him and quickly inserted them into thirteen acupoints in his body.

As the silver needle penetrated Wu Wen's body, internal strength burst out and formed a special rhythm.

Ripples surged, and in an instant, he entered a special state, and the nerves in his body became abnormally active.

When Wu Wen looked at Nagaruda again, although the illusion did not disappear, he saw a group of people wearing black robes with bat wings in the illusion.

They glided back and forth between the towering siege engines like bats in the night.

At the same time, they are like colorful moths, constantly scattering colorful perfume powder from their bodies while gliding.

In their hands, they also held a series of ritual instruments such as conch shells, hand drums, revolving wheels, bronze mirrors, etc.

"Sure enough, this Garuda is just an illusion!"

Wu Wen looked at the black-robed man flying in the sky with a serious look.

Illusion is a psychedelic technique that confuses people's consciousness by deceiving their five senses.

But analyzing from the current situation, the method of performing illusion is not as simple as deceiving the five senses.

This is because the illusion of Garuda cast by this group of black-robed men is definitely not just created by deceiving the five senses.

Wu Wen slowed down his pace and observed and collected information about the illusion more carefully.

With the help of Garuda.

The Tang army quickly broke through the city gates and rushed in. The defending army collapsed in an instant and was defeated.

Under the protection of his personal soldiers and generals, Liu Heita fought his way out and escaped from the city through another gate.

"Li Shimin, Li Shimin!"

Liu Heita, who escaped from the city, looked back at Xiangzhou City with a look of unwillingness on his face.

At the same time, it also reminded him of the battle of Hulao Pass that year.

At that time, Liu Heita was just a general under Dou Jiande.

At that time, Dou Jiande led an army of 100,000 to rescue Wang Shichong.

However, in front of Hulao Pass, they were defeated by Li Shimin's mere 3,000 troops.

The scene at that time was exactly the same as what we see today.

With the help of the "demon", Li Shimin led 3,000 men straight into the army of 100,000 and captured Dou Jiande alive, thus leading to the defeat of the army of 100,000.

"I just don't believe that you can always get help from 'demons'!"

Liu Heita's eyes were bloodshot with anger. He decided to return to Mingzhou and gather all his troops to fight Li Shimin again.

Then, he and his entourage crossed the Ming River and headed for Mingzhou City.

The overall situation in Xiangzhou City has been determined.

The army cleared the battlefield.

Except for a small number of personal troops who stayed in the city with Li Shimin, all other soldiers withdrew from Xiangzhou City and continued to be stationed in the big camp.

After returning to Dazhai.

Wu Wen immediately returned to the tent and quietly pondered the mystery of the "Garuda" illusion.

In Deng Dayong's view, this kind of "hands-off" behavior is laziness.

In response, he shook his head helplessly.

After dealing with military affairs, he went to the camp to report the situation to King Qi Li Yuanji.

After listening to the details of the war, Li Yuanji asked him about Wu Wen's situation.

"How did Wu Wen perform in this siege? How many heads did he behead?"

"Your Highness, Captain Wu did not kill a single enemy this time. He was even slack during the attack!" Deng Dayong told the truth.

Hearing this, Li Yuanji frowned, but didn't say anything. He just waved his hand and asked Deng Dayong to leave.

—

Inside the tent.

Wu Wen, who seems to be leisurely and doing nothing all day long.

Through the various information collected, in-depth analysis and deduction are carried out.

Finally, some of the mysteries of the 'Garuda' illusion were revealed, and that is the sound waves!
Sound waves, this seemingly ordinary natural phenomenon, actually contains terrifying power.

Whether it is low-frequency infrasound or high-frequency ultrasound, it can interfere with various organs and systems of the human body.

The low roar of infrasound can cause people to feel inexplicable fear and uneasiness.

The sharp and piercing sound of ultrasound can make people feel anxious and irritated.

Compared with simple deception of the five senses, this is undoubtedly a more advanced and sophisticated means of performing illusions.

However, in the "Garuda" illusion, this is only the basic function.

The main power of sound waves comes from their standing wave properties.

Standing waves are formed by the superposition of two sound waves with the same frequency, the same vibration direction, but opposite propagation directions.

This waveform does not move forward, but instead exhibits a steady state of vibration.

It is the stability of standing waves that allows sonic illusions to continue to work in a specific area, producing powerful and lasting illusion effects.

Wu Wen is deducing the model of spiritual space.

In-depth research on the formation conditions and control methods of standing waves.

He discovered that by precisely controlling the source and reflection surface of the sound waves, standing waves could be artificially created.

Moreover, by adjusting the frequency, amplitude and waveform of the sound waves, the characteristics of the standing waves, such as vibration intensity, distribution range and duration, can be further controlled.

This can not only create realistic hallucinations, but can also affect a person's thinking, emotions and even memory.

The same wave.

Wu Wen suddenly had an idea and replaced the sound waves with the electromagnetic waves that he was studying.

Since sound waves can form standing waves and produce such powerful illusion effects, can electromagnetic waves, a form of energy that also has wave properties, also achieve similar effects?
Although electromagnetic waves and sound waves are essentially different, they have many similarities in propagation, reflection, refraction, etc.

More importantly, electromagnetic waves have stronger penetrating power!
