The "No. 1 Forbidden Zone" is actually not a real forbidden area, it is just a conventional saying about the small courtyard by the people of the 407 Factory. Its official name is "No. 1 Experimental Field of 407 Factory".

Since it is an experimental site, it has a certain degree of secrecy and danger, and it is understandable not to let unrelated people enter and exit casually.

There is a security guard box at the entrance of the "No. 1 Forbidden Zone", and there are generally six security guards standing in the box, and the three-shift, 24-hour duty system is implemented. Judging from the number of security guards and the time of security, this is indeed the most heavily guarded place in the factory.

If you want to enter the "No. 1", you must have to issue a pass issued by both the secretary and the factory, and pass the post inspection. In addition, the experimental workshop of "No. 1" is also the first place in the factory to install magnetic card door locks.

At that time, automatic locks were still very rare, so even if someone could sneak in from the sentry post, they would not be able to enter the workshop.

But in the summer of this year, when Shen Yu came to the 407 factory, she found that due to the reduction of manpower, the original "No. 1" with strong barriers, the current security measures are simply useless.

Uncle Geng was fifty-nine years old at the time, and in another year, he would be able to get his pension.

"Oh, Xiao Yu, you're so tall! These eyebrows and eyes are exactly the same as when your father was young! When Shen Yu walked to the sentry box, Uncle Geng was still eating noodles there - he is still in charge of the canteen, although there are only four people in the factory at present, but he still adheres to the old rules of the factory - the canteen workers must wait for other workers to eat before eating.

Shen Yu originally came here with the idea of "exploring", to be honest, when she first saw Uncle Geng, she was still a little panicked.

In other words, the security guard at the sentry box saw that a child was approaching, and he had already started shouting-

"Go play somewhere else! Don't let you hang out here! ”

But this time, instead of driving her away, Uncle Geng beckoned to her.

"Girl, is it hot under the sun? Come on, come in, come in and rest, there's an electric fan here! ”

Shen Yu hesitated, but walked over.

"Girl, how about the cold noodles in the canteen at noon? It was made by the uncle. ”

"It's delicious." Shen Yu said.

"You've just had your eighth birthday, haven't you? I remember very clearly, you and my eldest grandson were born on the front and back feet - two dolls in the factory overnight! ”

Hearing Uncle Geng's words, Shen Yu couldn't help but feel a little sour in her heart - she had actually forgotten her birthday a long time ago, and her parents didn't seem to remember it.

The two of them are always busy, and it would be nice to go home and sleep at the same time. Since Shen Yu was a child, he has never encountered anything with a sense of ritual in life.

Uncle Geng had a good appetite, he snorted and ate all the noodles, then stood up and said, "Girl, can you help Uncle watch the door for a while?" I also had to go to the cafeteria to wash the pots, wash the dishes, and clean up. ”

Shen Yuhuo stood up: "But, Uncle Geng, this is not ......"

Uncle Geng sighed, slapped his back with his hand, shook his head and said, "You mean, this is 'No. 1', right?" What's the 'Number One' now? No one cares about it for a long time, no one cares about it for a long time - everyone is gone, who cares about this? You're not here, I'm also going to work after eating and wiping my mouth, I'm not a monkey, I'm not a hairless, how can a person look at the gate and clean up. ”

Uncle Geng shook his head gloomily, he walked out of the sentry box with his waist bent, and then turned a boulevard and walked in the direction of the cafeteria.

The thin Shen Yu sat alone in the sentry box, the electric fan whirring on the table, and the sky and the earth seemed to be filled with only the monotonous and boring sound of cicadas.

At this time, she stumbled upon an old card on the table, and a yellowed sticky note with the words "workshop door" written on it with a ballpoint pen on it.

Key card? Is this the key card that opens the "No. 1" workshop?

Shen Yu remembers that his father had the same card, and he was one of the first few experts in the factory to be awarded a door card.

- Dad had to take a break every day after lunch, and even if he woke up, he probably wouldn't be in the lab right away—Dad and his two assistants seemed pretty quiet during her vacation.

Thinking of this, Shen Yu picked up the key card from the table. She has always been careful in her work, and she took a special look at the card before taking it, remembering the angle and position of the card.

- Uncle Geng's old eyes are dizzy, he shouldn't find out, right?

Shen Yu slipped out of the sentry box, walked into the courtyard, and walked to the front of the huge workshop. The two iron doors of the workshop were tightly closed, and there was a small side door next to the iron door, and there was a protruding electronic lock on the door.

She put the key card close to the electronic lock, and there was a "Didi" sound at the door, and then only heard a loud sound from the gap in the side door, which felt like a person breathing a sigh of relief.

Shen Yu hesitated, but she still reached out and pushed open the door in front of her.

What appeared in front of her was a large, crowded space. Countless machines, large and small, are still running, and many green or blue screens are shining, and the lines and numbers on the screens are constantly scrolling.

There was a low roar of machinery in the workshop, like the snoring of the behemoths as they slew.

Shen Yu carefully shuttled between these large and small machines. She found a small house in the depths of the workshop separated by a brick wall, the door locked and the curtains tightly drawn.

- This is probably where Dad works, right?

She didn't try to push the door, let alone go inside—the study at home was a stack of books and notes, and she could probably guess what kind of office her father was without looking.

She continued to walk deeper into the workshop, and as she walked, she came across two boxy white instruments more than a meter tall and covered with buttons. After bypassing the two instruments, she saw something that was out of place in the entire workshop.

It was a huge "peacock bamboo and stone drawing" screen, this painting is about three meters long, two and a half meters high, and what is even more strange is that the metal bracket of the screen is quite far from the ground, and it "picks" the huge painting high in the air. With a distance of more than one meter from the bottom of the painting to the ground, eight-year-old Shen Yu can calmly pass through without even looking down.

On one side are rumbling modern machines, and on the other side are antique traditional screens – no matter how you look at it, there is a sense of disobedience.

Shen Yu looked at the huge screen, and at this moment, the sound of "Dididi" suddenly came from the two white instruments in front of the screen. She was taken aback and quickly bent down to burrow through the screen.

At this time, she realized that behind the screen was the end of the workshop, and there was a small door open, and the light that came in through the gap could tell that the door was not locked, but just hidden there.

The chirping of the white instrument became louder and louder at this time, and the most terrifying thing was that the huge screen suddenly slowly rotated on the stand!

Although Shen Yu was calmer than her peers when she was a child, she was still frightened and overwhelmed, she subconsciously pushed open the door in front of her and staggered out.
