After eight o'clock in the evening, three middle-aged men wearing maintenance uniforms arrived at Yu's house, each pushing a large equipment suitcase that looked quite sturdy.
The three people looked serious and said nothing. They followed Zhang Hai straight to the master bedroom upstairs, opened the suitcase 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 pot and had a sci-fi feel set up on the balcony of the master bedroom.
There were two military laptop computers nearby, connected to two buzzing black metal boxes that resembled servers.
Two men sat cross-legged on the ground, concentrating on operating laptops.
Yu Zhiming walked into his soundproofed bedroom and found that in the open space in front of the bed, a 32-inch display screen was propped up with metal brackets. There were also two columnar speakers nearly one meter high placed on the left and right sides of the screen.
There is already an image on the screen, it is a large safe as tall as a person...
Zhang Hai told Yu Zhiming how to adjust the volume, then left the soundproof bedroom with another decoration man, and quietly closed the soundproof door.
As the soundproof door closed, the world where Yu Zhiming lived seemed to have pressed the mute button, becoming silent for a moment.
But after a while, a rustling sound sounded in Yu Zhiming's ears, and gradually became clearer.
This is the sound coming from the column speakers.
Yu Zhiming made a little distinction and found that it was the sound of shaking clothes, breathing, and heartbeat...
These voices came from two people, one tall and strong, the other petite. Yu Zhiming judged that they were a male and a female.
Seeing that there was no movement on the other side, Yu Zhiming had no choice but to urge: "Comrades, I'm ready, let's start the test."
"You can actually tell it's two people?"
Following this voice, a head suddenly appeared without warning and almost filled the entire display screen in front of him.
Yu Zhiming took a step back involuntarily.
He looked at the big head with a black mask on the screen and no eyes. He calmed down and urged again in a very 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.
This person put a hand-sized object with two antennas and a suction cup-like object on the safe.
Then, the petite man gently turned the combination disk on the safe.
At this moment, the breathing, heartbeat and other noises that Yu Zhiming heard before all disappeared, and turned into the sound of the rotating and rubbing of the cipher disk.
The sound was so clear that Yu Zhiming looked at the safe on the screen and directly followed the signal transmitting the sound, penetrating an unknown distance and then through the safe, "seeing" clearly what was inside.
The structure of...
This safe has a total of three combination disks, that is, three sets of nine combinations.
As if Yu Zhiming was immersed in the scene, he could distinguish it without any difficulty.
"3,7,2!"
"6,2,8!"
"5,7,4!"
Seeing that the safe door was opened a crack, Yu Zhiming felt that his intention was still unfinished, and it felt like it had started but ended.
The previous 007's special warfare atmosphere of going deep into the tiger's den is so full, is this the work to be completed?
It's too unchallenging to finish it in ten or twenty seconds.
Yu Zhiming was a little disappointed, but then he thought of something and immediately became excited again.
Isn’t this set of 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 subtle sounds and transmit it with such high fidelity, in the future, when he works at Huashan Second Hospital, he will also be able to conduct physical examinations on patients in Huashan Hospital remotely.
In this case, Yu Zhiming doesn't have to run around. After all, the 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 haircut, thick eyebrows, big eyes, and a square face appeared on the screen.
"Doctor Yu, you passed the test. To be precise, the ability you demonstrated far exceeded our expectations."
"I must say, it's amazing."
The middle-aged man spoke and gave Yu Zhiming a thumbs up.
Yu Zhiming said modestly: "The main reason is that your equipment is so powerful. It can not only collect very subtle sounds, but also transmit them intact."
Just as Yu Zhiming was thinking about how to ask for help, the middle-aged man on the screen spoke again.
"Doctor Yu, our people have already started taking action. The real challenge will begin in about half an hour."
Hearing this, Yu Zhiming perked up again and completed the real work before he could claim credit based on his merits.
He listened carefully to the middle-aged man's introduction, "Doctor Yu, I must explain that the actual combat environment is definitely different from the test environment, and the sound quality and image quality are definitely much different."
"Also, we currently don't know the specific structure of the safe we are facing."
"Isn't it the safe in the test?" Yu Zhiming asked in confirmation.
The middle-aged man shook his head and said, "No."
"The information we currently have is that this safe is a product carefully designed by a combination lock master."
"After the safe was manufactured, he invited five well-known lockpicking masters. None of these five people successfully opened it within twenty-four hours."
Yu Zhiming said with high spirits: "I like challenges."
The more difficult the task is to complete, the greater the credit will be, and the more confident you will be to ask for this set of equipment...
In order to successfully complete the task, Yu Zhiming began to close his eyes to rest and recharge his batteries...
Until I heard, "Doctor Yu, let's start!"
When Yu Zhiming opened his eyes, he saw that the image on the screen was shaking and the light was dim.
However, he could distinguish a metal door displayed on the screen, with nine spherical handles in a row across the door.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! There is also a circle of fine scales engraved on the handle, and Yu Zhiming can confirm that it is 360 scales.
Immediately afterwards, Yu Zhiming saw something that looked like a suction cup sucked on the family door.
Three or four seconds later, Yu Zhiming saw another gloved hand gently turning the first spherical handle on the left hand, and finally a subtle sound came from the column speaker...
Just this sound...
Yu Zhiming didn't hear any sound of gears, only a slight friction sound.
There is 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 sloshing, and it is still a very dense liquid." Yu Zhiming made his judgment.
At this time, a strange man's voice suddenly sounded, "High-density liquid? It should be mercury."
"I understand, the mercury-filled sphere is insulated, but it must be inlaid with two points of metal, which can be connected to the outside world through the mercury to form a conductive path."
Upon hearing this analysis, Yu Zhiming immediately had a picture in his mind, a glass ball filled with half of the mercury, with a small piece of metal inlaid at each end of the glass ball.
What Yu Zhiming wants to do is to connect the metal on the glass ball with the metal outside through the mercury.
This difficulty is extraordinary, and it is much more difficult to distinguish than the password mechanism with gears as the main body.
Yu Zhiming wanted to find the almost insignificant difference in the extremely subtle friction sound.
In order to successfully complete this mission, and to ask for this set of sound collection and transmission equipment confidently, Yu Zhiming went straight to full fire. The blood flowing into the brain increased by nearly 20% compared with before. His ears moved involuntarily, allowing himself to enter a state of total selflessness.
Concentrating on...
In his mind, a huge glass ball was slowly rotating, and the mercury inside was rippling slightly from side to side.
Accompanied by a scraping sound that is sometimes strong and sometimes weak...
Suddenly, there was a slightly silky sound, which gave Yu Zhiming a different feeling.
"stop!"
He subconsciously shouted stop, and then said: "Turn ten small scales..."
