How did you, a prisoner on death row, become an important weapon of the country? Yecheng Gao Weiming

"Lian Hai..."

After hearing the electronic sound in her mind, Anna was a little frightened and subconsciously clenched Zhang Lianhai's hand.

Zhang Lianhai wanted to hug his girlfriend to comfort her, but when he saw Pushkin standing beside her, he felt even colder.

He said in a rather stiff tone: "What are you afraid of! Anna, it's just a virtual challenge. Why don't you just treat this as a game?"

"Yeah?"

Anna murmured to herself, feeling heartbroken when she saw Lian Hai's subconscious distance from her.

"Yeah! My friends, the goddess of luck favors me again!"

The black guy next to him started shouting excitedly.

His face was full of joy and he took the initiative to look at the other three challengers.

"Hello everyone, I...let me introduce myself again."

"My name is Matthew. I'm from South Africa and I'm studying for a doctorate at the University of Cape Town. My research area is medical physics..."

"It looks like we have won this challenge! The organizers are definitely testing our knowledge of medical physics!"

"Matthew?"

Zhang Lianhai turned around and recognized the black man.

He shook his head in a daze. Why did he feel that he didn't notice this guy at all when he passed by the corridor just now?

However, he was also delighted to hear Matthew's self-introduction.

Medical physics?

A very unpopular subject.

Even many universities in Longguo do not offer this course. It seems that only the top medical universities offer such a course, but it is definitely not treated as a major.

After all, medical physics is widely used in radiology treatment, and it is a profession that can be mastered with a little personal training.

But Zhang Lianhai knows that this subject is not that simple.

Today, Longguo's large-scale CT and MRI machines, MRI, four-dimensional color ultrasound, DR imaging systems, high-end testing equipment, etc., are all dependent on imports, simply because foreign countries attach great importance to medical physics.

In addition, the medical major of the University of Cape Town in South Africa is also well-known in the world and has produced many Nobel Prize winners in medicine.

This challenge has the help of this black brother...

Is it really stable?

Zhang Lianhai forced a smile and extended his hand.

"Hello, Matthew, my name is Zhang Lianhai, from Longguo..."

"this is mine……"

He looked at his girlfriend beside him, paused for a moment and changed the subject: "My friend, Anna, is from Mao Xiong..."

Matthew shook hands enthusiastically, smiling: "Okay, okay! Lian Hai, Anna, nice to meet you... This is..."

He wanted to shake Pushkin's hand again, but Pushkin snorted coldly.

"Let's start the challenge, everyone! Didn't you hear what the AI ​​said? The sooner we finish, the more points we'll get!"

After saying that, Pushkin turned around, pushed open the hospital door, and walked in with his head held high.

This made Matthew feel embarrassed and he turned around to look at Zhang Lianhai.

Do you know each other?

Zhang Lianhai sneered, "Stupid guy, I will kill him sooner or later!"

After saying that, he took Anna into the hospital.

Matthew rolled his eyes speechlessly, thinking that something bad might happen soon!

As the three people walked in, a cold wind blew and a shadow seemed to pass through the darkness. Matthew was so scared that he quickly followed them in.

It's strange.

Once all four of them entered the six-story hospital building, the wooden door slammed shut, seemingly blocking out all the sound of thunder and rain outside.

Zhang Lianhai, Anna and Pushkin have stood in the middle of the hall, looking at the decoration style here.

Dark, decayed, and a bit eerie.

As expected of a hospital from the early 20th century, it does not have the white structure common to modern hospitals, but is basically composed of red wooden decorations.

Wooden corridors, wooden escalators, wooden furniture...

On the dome of the hall, there is a Western oil painting painted with paint.

Under the dim light, the characters in the oil painting are looking down at everyone from a high position, and a special feeling emerges in everyone's mind.

Not surprising when you think about it.

The second industrial GM is in full swing, but most of its efforts are concentrated in the manufacturing, chemical and automotive industries.

A large number of new buildings have sprung up, and new decoration styles have gradually begun to be determined.

As for old hospitals like this, who knows how many years it has been built.

On a rainy day late at night, cold wind blew in from the window, mixed with the smell of disinfectant and unknown substances, and a disgusting smell hit me in the face.

"call……"

Zhang Lianhai exhaled a breath, supported his girlfriend and walked a few steps deeper, and let out a soft cry.

"anyone there?"

Since this challenge was upgraded to a virtual scene challenge, he was not afraid.

It was only because the injury on Anna's forehead urgently needed bandaging that Zhang Lianhai cried out softly.

However, with the rules in place, he tried his best to keep his voice within a reasonable range, around 50 decibels.

Here, we need to briefly explain the decibel classification levels.

0-20 decibels is generally called silence, which means there is no sound around or even a slight sound such as wind blowing.

20-30 decibels is similar to the whisper between people, subtle and unnoticeable.

30-40 decibels is like a quiet late night, accompanied by the chirping of insects and occasional birds.

40-60 decibels refers to the noise near the window during the day, such as car horns and pedestrians talking.

Generally speaking, when the noise level reaches 70-80 decibels, it is a busy street or people are talking loudly.

By this time, it was a bit noisy for people who liked quiet.

If the sound exceeds 80 decibels, or even is below 110 decibels, it is the sound of a heavy truck rumbling past and the noise of a car honking at a close distance.

If it reaches 120 decibels, it will cause great interference to people, such as the roar of a diesel engine, the cutting sound of an angle grinder, or the firing sound of a pistol bullet.

People cannot stand levels above 130 decibels, such as standing next to the wing of a propeller plane or listening to the roar of a Gatling gun.

140 decibels is equivalent to watching a rocket take off from the ground at close range, and 150 decibels is equivalent to a nuclear bomb exploding next to your ear...

Scientific research shows.

The maximum sound level that humans can withstand is 120 decibels. Any sound level exceeding this level will inevitably cause damage to hearing.

Similarly, a person's scream can instantly reach about 130 decibels, and if the tone is right, it can even shatter an intact glass.

Since the rules stipulate that no noise above 100 decibels can occur in this challenge, Zhang Lianhai just needs to try to avoid it.

Because normal conversation will never exceed this limit.

Who knows.

With just this neither loud nor soft shout, there was immediately movement deep in the hospital lobby.

Several people tensed up and looked over with frowns.
