Hello, Mr. Major General

“The main purpose of my system is to accurately locate the target. I have no other intentions,” Lu Jin said firmly.

Huo Shaoheng still tried to persuade him, “Actually, I think Uncle’s system has more room for exploration. For example, if we cooperate with the global satellite navigation system…”

He wanted to use the globally supported Nandou satellite system to attract Lu Jin’s interest.

Lu Jin chuckled and raised an eyebrow with a hint of arrogance. “If necessary, I can hack into any satellite system in the world and use the global satellite resources to achieve true, all-encompassing surveillance of any target.”

Huo Shaoheng was at a loss of words.

He was actually trying to come up with ideas on the spot.

Huo Shaoheng had almost never been impressed by anyone, but in front of Lu Jin, he felt that this man was an exception.

Gu Nianzhi listened from the side, and her feelings were complicated. She thought about it for a moment, then whispered, “My dad doesn’t have to do this, and he doesn’t have the ambition to dominate the world. All he needs is a lab like this for him to immerse into the world of technology and data.”

Lu Jin nodded repeatedly. “That’s right, that’s right! Nianzhi is right! That’s exactly what I was thinking!”

“Let me tell you, it was thanks to this system that I discovered abnormal fluctuations in the energy of the magnetic field. I also discovered that He Chengjian had actually sent people to abduct Nianzhi…”

Lu Jin had no choice but to fight an energy battle with He Chengjian. Although there was no smoke, it was extremely destructive.

Now, he was using this advanced system that could monitor targets anywhere in the world to analyze an inconspicuous ward.

Not only was everything in the ward analyzed into data, even the air flow in the ward could not be hidden from him.

“Nianzhi, I’m going to perform a magic trick for you now. Watch carefully,” Lu Jin said as he focused his attention on the analysis of the data in the video.

“The problem in this ward is indeed related to the air.”

“But it’s not bacteria or viruses. This possibility has been ruled out.”

“Then what is it related to? We can start with the central air-conditioning system of the entire building.”

“Under normal circumstances, a sealed ward has a central air-conditioning system. The air flow should be self-circulating and self-integrated.”

“But look…” Lu Jin pointed to a group of data. “This group of data doesn’t show such simple air flow.”

“You can see it clearly here. Among all these air flow data, there’s a group that shows that air is continuously flowing towards the corner where He Zhichu is sitting.”

“Or rather, this isn’t simple air flow. There’s another kind of energy present inside.”

Lu Jin clicked on the air data again with his mouse, instructing the system to carry out further analysis.

Soon, the computer system came to a conclusion after precise calculations.

“Look, this is the result of the computer system’s analysis.”

“The other type of energy that follows the flow of air is sound waves. To be precise, it is a group of infrasonic waves below 20 hertz.”

Infrasound weapons!

Huo Shaoheng’s eyes flashed.

So the culprit was infrasound weapons!

There were people using such weapons here?

He recalled that there had been an incident where an infrasound weapon had injured someone in the Other World. It had happened during Gu Nianzhi’s abduction and disappearance.

Lu Jin did not know about the Other World. He continued to explain, “For sound waves, the frequency that the human ear can hear is between 20 hertz and 20,000 hertz. Sound waves that have a frequency lower than 20 hertz are called infrasonic waves. Sound waves that have a frequency higher than 20,000 hertz are called ultrasonic waves.”

“Infrasound weapons, as the name suggests, are weapons that use infrasonic waves to kill enemies.”

“Because different organs in the human body have different pulsations of different frequencies, these pulsations happen to be in the same frequency range as infrasonic waves. In other words, they are in the range below 20 hertz.”

“Therefore, infrasonic waves of different frequencies will resonate with different organs in the human body. Infrasound weapons use this feature to injure.”

“An infrasound weapon can cause mental and physical damage to the human body. Mild damage causes nausea, vomiting and dizziness, while severe ones will cause mental disorder, pain all over the body, and even death due to ruptured internal organs.”

“He Zhichu’s condition was caused by continuous attack of an infrasound weapon of a specific frequency. However, because the enemy did not find the correct resonance frequency, it took a full 24 hours for physical damage to be done to his body.”

“If I were to control this infrasound weapon, I would only need two seconds to paralyze anyone within attack range of the weapon.”

Lu Jin seemed to shake his head regretfully. “The infrasound weapon they used could be said to be very crude.”

Gu Nianzhi’s mouth opened, but before she could speak, Huo Shaoheng had already asked with a frown, “But the flaw of the infrasound weapon is also very obvious. May I ask how they managed to resolve this flaw?”

“What flaw?” Gu Nianzhi quickly asked, “It sounds very powerful, and it looks like they’re attacking without any bloodshed…”

“Yes, they’re indeed attacking without bloodshed, but they also might not be attacking without bloodshed,” Huo Shaoheng sat leisurely on the sofa and crossed his legs. He calmly said, “The infrasound weapon has a very big flaw, which is that it attacks indiscriminately. That is to say, it doesn’t differentiate between friend and foe. It’s very easy for both sides to be injured.”

This kind of weapon, which could kill a thousand enemies while also injuring a thousand allies, was of little use in war.

Lu Jin nodded approvingly and said, “That’s true. Infrasound weapons not only attack indiscriminately, but also have a specific range of attack. If they’re too far away, it won’t be of much use.”

“Yes, the instruments that emit infrasonic waves must be not too far from the target. Then where exactly is the source of their infrasound?” Huo Shaoheng was obviously more interested in military technology.

Lu Jin excitedly pointed at the two small rectangles that had appeared under the convex shape and drew a line with the mouse. He said, “Look at what’s inside this.”

He double-clicked the mouse and had the system analyze the two small rectangles that were hidden on both sides of the ward.

On the monitor screen, the two small rectangles that Lu Jin had drawn with the mouse were shown to be a whiteboard, and there was nothing there.

However, Lu Jin entered a string of commands and said with a smile, “Daddy’s Trick is continuing!”

At this moment, the two small rectangles that were originally empty suddenly seemed to have been manipulated magically, revealing the hidden treasure underneath:

Two instruments that were both the same shape as a large drum gradually appeared at the two empty small rectangles.

“Look, the large black gauze disk in front of the drum is actually a circular amplifier.”

Lu Jin pointed at the two instruments that were revealed and said, “These are the culprits behind the infrasonic waves. They fired infrasonic waves at He Zhichu for at least 24 hours before he fainted.”

Gu Nianzhi was very surprised. “Why did it take so long? Young Master must have suffered a lot…”

“… I don’t know why it took so long either.” Lu Jin smiled. “It depends on how the people over there designed it.”

Gu Nianzhi looked at the data modeling of the ward on the monitor, suddenly, she asked, “Since you said that infrasound weapons attack indiscriminately, why is Young Master the only one unconscious? Qin Yaoguang had managed to hold on for a while, while Old Master Qin is completely normal.”

Lu Jin smiled at her and praised, “That’s a good question! Why? I’ll show you the reason now.”

At this moment, Lu Jin moved the Mouse to Old Master Qin, who was lying under the oxygen mask on the hospital bed.

Old Master Qin’s oxygen mask was not a normal oxygen mask. It didn’t just cover his nose, but covered his entire body.

Lu Jin moved the mouse over the oxygen mask and said, “Look at the data.”

The font size of the data was as small as a grain of rice and densely arranged on the oxygen mask, so they couldn’t see what it meant.

Lu Jin pointed at the data and said, “Look at this oxygen mask carefully.”

Gu Nianzhi shook her head. “I don’t understand. Please explain.”

Huo Shaoheng carefully observed the oxygen mask and suddenly said, “This oxygen mask is complicated. It has two layers of glass with vacuum in the middle.”

Lu Jin smiled, “Yes, that’s why.”

“Because the biggest weakness of the infrasound weapon is not that it attacks indiscriminately, but that it is too easy to intercept it. As long as a vacuum zone is established around the target, a subsonic wave cannot harm it.”

Gu Nianzhi understood and quickly said, “So this double-layer full-body oxygen shield is actually creating a vacuum barrier around him, shielding him from the infrasound weapon.”

Lu Jin looked closely at the oxygen mask on Old Master Qin’s hospital bed on the display screen and pursed his lips.

He said lazily, “This old guy really cherishes his life. The oxygen mask on his body is no ordinary oxygen mask.”

“Not only does it provide oxygen, but it also shields against all external sources of energy, including but not limited to electrical, magnetic, light and sound energy.”
