A nation's industrial development begins with junior engineers.

"Zizzi-"

The distinctive sound of a dot matrix printer drifted through the small building.

Old Wang squatted next to the printer, holding the freshly printed paper in his hands, looking at it with great interest, forgetting to swallow the mouthful of instant noodles he was slurping for a long time.

"Good heavens! Red ropes to mark the area! Hey! This Mulan girl has really mastered the art of street vending!"

"And that Jin Zhen kid, he commanded the machine to work with just five keystrokes? That's cool! He really makes me proud!"

"Hey, you'd never guess that Jinzhen, such an introverted guy, would actually strike up a conversation with someone!"

What's so hard to see? If you were in that situation, wouldn't you also want your motherland to lose face in that kind of setting?

Let alone initiating a conversation, even things you resist doing are not off-limits!

Jiang Xia shook his head and looked back at the slowly spinning tape.

Well, without verification tools, I don't know if this data can be transmitted completely.

Old Wang didn't have many worries; he just kept reading travelogues. But as he read, his joy turned to sorrow.

The paper in my hand came to an abrupt end at the most exciting part: "The printer started continuously spitting out the agenda, causing a sensation throughout the room."

What happened next?

What were those foreigners' expressions like?

Has the C programming language been standardized by the IEC conference?

Old Wang was so anxious he was scratching his head, staring longingly at the printer. It was still creaking and groaning as it worked, but at a slower speed…

His frantic pace seemed almost agonizing in comparison to his own.

The new content gradually takes shape above the print head, and the characters appear one by one as if crawling.

"Oh my god, this is driving me crazy!" Old Wang finally couldn't hold back any longer and turned to shout into the inner room:

"Jiang Xia! Bro! Can you speed up this printer? It's like squeezing toothpaste! Can't you tech guys just make it print all at once?"

Jiang Xia replied without looking up, "Yes."

"Really?" Old Wang's eyes lit up, and he forgot about the half-finished "novel" in his hand, moving closer to the partition.

“Hmm. This kind of thing,” Jiang Xia pointed to the creaking metal machine outside, “is called impact dot matrix printing. It relies on the needle hitting the ribbon to ‘print’ out one character at a time. The physical limits are there; it can’t be much faster.”

He paused, remembering how he'd smeared Secretary Liu's hand with snot. He chuckled, "It's been a while since I've heard him nag; I kind of miss it."

"If you want to get it out in a flash... you need a different approach. No need for a firing pin, just use it all."

"Light?" Old Wang was taken aback. "You can make words appear on paper by shining light on them?"

"It's not a direct photo."

Perhaps the data transmission delay also needs something to fill the gap, so Jiang Xia prepared to explain it clearly to Lao Wang.

"The principle is roughly like this: using a material that is particularly sensitive to light, an invisible electrostatic text pattern is first 'drawn' on it with a laser beam, and then toner with opposite charges is attracted to it, and then transferred to paper and fixed by heating."

The whole process can be very fast, quiet, and much more precise.

In theory, a complex page of text and images can be completed in a few seconds.

The scene he sketched out in just a few words left Old Wang speechless.

No need for a firing pin? Using light to "draw" the characters?

How many seconds per page?

This doesn't just sound like "faster," it sounds like magic!

Hmm, no, the happiest person to print so quickly must be Secretary Liu, right?

Old Wang shuddered at the thought: Forget it, let Jiang Xia work on this slowly, and it's best to finish it when I'm middle-aged...

The young badge warrior who had been standing guard nearby, listening intently to Lao Wang reading his travelogue, was initially somewhat interested in the conversation between Jiang Xia and Lao Wang. However, when he heard Jiang Xia begin to describe something completely incomprehensible but that he felt was bound to cause some serious trouble, he immediately became alarmed.

Jianggong is up to something again!

The soldier instinctively wanted to get away from the center of this "technological storm." He pretended to check the window latch, quietly moving his body towards the window, wondering if he could climb out of the second-floor window onto the old locust tree next to it and then jump down.

Just as his hand touched the cold window frame and one leg had quietly lifted, preparing to carry out a "strategic retreat," his movements suddenly stopped.

"what?"

"Captain, Xiao Jiang! Did you guys forget to go to the meeting? It looks like someone's here to arrest you!"

? ? ! !

The soldier pointed out the window: "Look! Two jeeps are coming towards our building! Judging by their appearance..."

Before the words were even finished, the screech of brakes came from outside the building, followed by the thud of car doors opening and closing, and the sound of hurried and chaotic footsteps.

The atmosphere in the room suddenly became tense.

The printer was still slowly creaking and groaning, the CD burner was spinning at a steady speed, and the footsteps outside the window were already clearly audible, rapidly approaching the stairwell.

Old Wang deftly gathered the classified documents he was looking at together, stacking them neatly, and then moved the table towards the door.

This angle is tricky; if anyone dares to kick the door without following the rules, the door will hit the corner of the table as soon as it opens, and the pile of classified materials on the table will surely scatter all over the floor.

"Come on, come on. My sweeping leg is ready!"

If the other person's shoe dares to step on any piece of paper with writing on it, he is absolutely confident that he can take them down and subdue them in the next instant. Why?

A violent attack was launched on a classified work site in an attempt to destroy confidential documents!
