Chapter 1366: Full Firepower
After eight o'clock in the evening, three middle-aged men in maintenance worker uniforms came to Yu's house, each pushing a large equipment suitcase that looked quite sturdy.
The three of them, with serious expressions and no words, followed Zhang Hai straight to the master bedroom upstairs, unpacked the suitcases, and got busy...
Nearly an hour later, Zhang Hai came downstairs and told Yu Zhiming that it was okay.
Yu Zhiming went upstairs to the master bedroom and saw a complex device that looked like a satellite dish and had a sci-fi feel installed on the balcony of the master bedroom.
There were two military laptops nearby, connected to two humming black metal boxes that resembled servers.
Two men sat cross-legged on the ground, concentrating on operating their laptops.
Yu Zhiming walked into his soundproof bedroom and found a 32-inch display screen supported by a metal bracket in the open space in front of the bed. There were two nearly one-meter-high columnar speakers placed on the left and right sides of the screen.
There was already an image on the screen: a large safe more than a meter tall...
Zhang Hai told Yu Zhiming how to adjust the volume, and then left the soundproof bedroom with another decorator, and closed the soundproof door quietly.
As the soundproof door closed, Yu Zhiming's world became silent as if the mute button had been pressed.
But after a while, a rustling sound rang in Yu Zhiming's ears and gradually became clearer.
This is the sound coming from the column speaker.
Yu Zhiming made a quick distinction and realized that it was the sound of clothes swaying, as well as breathing and heartbeats...
These voices came from two people, one tall and strong, the other petite. Yu Zhiming judged that they were a man and a woman.
Seeing no movement from the other side, Yu Zhiming had no choice but to urge: "Comrades, I'm ready here, let's begin the test."
"You can actually tell there are two people?"
Along with the sound, a head suddenly appeared without warning and almost covered the entire display screen in front of him.
Yu Zhiming involuntarily took a step back.
He looked at the big head on the screen, covered with a black mask that didn't even reveal its eyes. He calmed himself down and urged again in an unhappy tone, "Hurry up and start!"
The next moment, the big head left the screen, and Yu Zhiming saw a petite guy, also wearing a black mask, standing in front of the safe.
The man attached a palm-sized object with two antennas and a suction cup shape to the safe.
Then, the petite person gently turned the combination dial on the safe.
At this moment, all the breathing, heartbeat and other noises that Yu Zhiming had heard before disappeared, and were replaced by the creaking sound of the cipher disk turning and rubbing.
The sound was so clear that Yu Zhiming looked towards the safe on the screen. The sound signal directly followed the sound, penetrating an unknown distance and then penetrating the safe, allowing him to clearly see the structure inside...
This safe has three combination disks, which means three sets of nine combinations.
Yu Zhiming, as if he were there in person, could distinguish them without any difficulty.
“3, 7, 2!”
“6, 2, 8!”
“5, 7, 4!”
As the safe door was opened a crack, Yu Zhiming felt that he had not finished yet and that the experience had started well but ended poorly.
The atmosphere of the special operations deep into the tiger's den in 007 was so strong, but is this all the work to be done?
It's too unchallenging to finish it in ten or twenty seconds.
Yu Zhiming was a little disappointed, but then he thought of something else and immediately became excited again.
Isn’t this sound collection and transmission equipment exactly what Teacher Qi Yue and he have been looking for?
With such audio-visual equipment that can collect all the subtle sounds and transmit them with such high fidelity, he will be able to perform physical examinations on patients of Huashan Hospital No. 2 remotely while working there.
In this way, Yu Zhiming wouldn't have to run around. After all, a one and a half hour drive is quite tiring.
Unexpectedly, there was an unexpected big harvest.
When Yu Zhiming was feeling happy, he saw the scene on the display screen change. A middle-aged man with a flat head, thick eyebrows, big eyes and a square face appeared on the screen.
"Doctor Yu, you passed the test. To be more precise, the abilities you demonstrated far exceeded our expectations."
"I have to say, it's amazing."
As the middle-aged man spoke, he gave Yu Zhiming a thumbs up.
Yu Zhiming said modestly, "It's mainly because your equipment is amazing. Not only can it pick up very subtle sounds, but it can also transmit them intact."
Yu Zhiming was just thinking about how to ask for it when the middle-aged man on the screen spoke again.
"Doctor Yu, our people have already started the operation. The real challenge will begin in about half an hour."
Hearing this, Yu Zhiming became energetic again. He completed the real work so that he could ask for the reward based on his merits.
He listened carefully to the middle-aged man's introduction. "Doctor Yu, I must point out that the actual combat environment is definitely different from the test environment. The sound and picture quality will definitely be much worse."
"Also, we currently don't know the specific structure of the safe we are facing."
"Isn't this the safe being tested?" Yu Zhiming asked for confirmation.
The middle-aged man shook his head and said, "No."
"The information we have at this point is that this safe was carefully designed by a master locksmith."
"After the safe was built, he invited five well-known locksmiths to try it. None of them succeeded in opening it within 24 hours."
Yu Zhiming said with high morale: "I like challenges."
The harder the task, the greater the credit, and the more confident you'll be in asking for this equipment...
In order to successfully complete the task, Yu Zhiming began to close his eyes and rest, gathering his strength...
Until I heard a voice in my ears, "Doctor Yu, it's started!"
When Yu Zhiming opened his eyes, he saw that the image on the screen was shaking and the light was dim.
However, he could make out a metal door displayed on the screen with nine knobs arranged in a horizontal row.
There is also a circle of fine scales engraved on the handle, and Yu Zhiming can confirm that there are 360 scales.
Immediately afterwards, Yu Zhiming saw a suction cup-like object stuck to the family door.
Three or four seconds later, Yu Zhiming saw a gloved hand gently turning the first knob on his left hand, and finally, a faint sound came from the columnar speaker...
Just this sound...
Yu Zhiming didn't hear any sound of gears, only a slight friction sound.
There's also a shaking sound...
"Turn the handle faster." Yu Zhiming said.
The next moment, Yu Zhiming heard a more obvious shaking sound.
"There is liquid shaking, and it is a very dense liquid." Yu Zhiming made his judgment.
At this moment, a strange man's voice suddenly sounded, "High-density liquid? It should be mercury."
"I understand. The sphere containing mercury is insulating, but it must be inlaid with two metal points that can connect to the outside world through the mercury to form a conductive path."
After hearing this analysis, Yu Zhiming immediately had an image in his mind: a glass ball half filled with mercury, with a small piece of metal inlaid at each end of the glass ball.
What Yu Zhiming needs to do is to connect the metal on the glass ball with the metal outside through mercury to form a pathway.
This is extremely difficult and is much more difficult to distinguish than a cipher mechanism based on gears.
Yu Zhiming wanted to find the almost insignificant difference in the extremely subtle friction sound.
To successfully complete this mission, and to confidently claim the sound collection and transmission equipment, Yu Zhiming went all out. Blood flow to his brain increased by nearly 20% compared to before, and his ears twitched involuntarily, allowing him to enter a state of complete and utter concentration...
In his mind, a huge glass sphere was slowly rotating, and the mercury inside was slightly rippling left and right.
Accompanied by the sometimes strong and sometimes weak scraping sound...
Suddenly, a slightly silky "ning" sound gave Yu Zhiming a different feeling.
"stop!"
He subconsciously called out "Stop," and then said, "Turn back ten small scales..."
"Four more ticks clockwise..."
"Okay, next handle..."
