303 dormitory.

Lu Chen was awakened by the cold touch beside his pillow.

When you open your eyes, you will see a black metal block.

Last night, he put the black metal block next to his pillow, almost sleeping all night, and didn't fall asleep until the early morning, and his eyes were now covered in blood.

Get up and wash up.

The people in the dormitory talked and laughed together and walked towards the cafeteria.

As usual, Lu Chen followed the army, but he talked a lot less. Everyone thought he was still worried about finding a job and internship in the senior year, so he didn't care.

Lu Chen spent the whole morning in a daze, and his emotions were surging in his heart. He kept guessing what the black metal block in his hand was, and even had the idea of ​​skipping class research.

But reason made him forcefully suppress this impulse and wait for the course to end.

The courses for the second semester of junior year are not tense, especially when the exam week is approaching, many courses are over, and the rest of the time is left for students to review freely.

afternoon.

After the day's class, Lu Chen greeted his roommate and returned to the dormitory alone.

All three of them went to the study room to study, and at this time, Lu Chen was the only one left in the dormitory.

After locking the door, Lu Chen took out the black metal from his pocket with trembling hands.

After a careful look, there was no sign of the strangeness of the black metal from the outside, and the weight was not far from the lost phone.

Taking a deep breath, Lu Chen picked up the book "Software Architecture and Design Pattern" again and read it carefully.

While he looked, Yu Guang was paying attention to the changes in the ferrous metal blocks.

Here comes!

Sure enough, a light appeared on the black metal block again, just like a black screen phone suddenly turned on, and a line of text suddenly appeared and disappeared quickly.

The content of the text is exactly what Lu Chen just read.

this......

Lu Chen picked up the black metal block again, but there was still no abnormality.

"So, what I'm watching will appear on this strange machine."

Lu Chen said intimately.

Now, Lu Chen has only two doubts left in his heart.

1. How can the text appear on ferrous metal blocks?

2. What is the use of the text content that appears on the ferrous metal block?

Don't worry, try one by one.

He is basically sure now that as long as he reads the book carefully, the words will definitely appear on the ferrous metal blocks.

So...what can you see it at a glance?

Thinking of this, Lu Chen looked at the book "Software Architecture and Design Pattern" with a glance.

In three seconds, he quickly browsed the contents of one page.

After glancing, the text on the black metal was still rapidly emerging, without any difference because Lu Chen did not look carefully.

Keep trying.

Lu Chen is basically sure that reading books carefully and not reading books seriously will not affect the emergence of text on ferrous metal blocks.

If you look carefully, the speed of text appearing on the ferrous metal block is slower. If you browse quickly, the speed of text appearing on the ferrous metal block becomes very fast.

After such a long time of experimentation, Lu Chen felt that texts constantly appearing on ferrous metal blocks must have some special effect.

But there is too little information disclosed so Lu Chen can't grasp the key points.

But at least one thing is certain that this black metal block has a great relationship with him, and he seems to be equivalent to the medium of a black metal block.

That's right, it's the medium.

However, for a while, he couldn't figure out what the purpose of these emerging words was.

"Forget it, no matter what, I will finish all this book first."

Making up his mind, Lu Chen began the crazy book-flipping mode.

A book "Software Architecture and Design Pattern" has a total of 310 pages from the introduction of the content to the last page.

Normally, even if Lu Chen has learned it once, it will take at least one week to chew it seriously from beginning to end.

But now, Lu Chen has finished turning the book from beginning to end at less than three seconds per page, which takes less than fifteen minutes in total.

"Huh! That's the end?"

Lu Chen exhaled a breath of turbid air and murmured.

He didn't know what the meaning of doing this was, maybe it was just a meaningless attempt.

He smiled self-deprecatingly, and Lu Chen looked at the ferrous metal.

Who knows...

The ferrous metal, which was originally just the contents of the book, has changed again.

Countless texts and pictures appear like waterfalls on black metal, like data flows in computer codes, which are dazzling.

Then, countless data streams were collected into a book - "Software Architecture and Design Pattern".

Finally, the book also disappeared, and the black metal block fell into darkness again.

"That's all...well?"

Before the words were finished, the ferrous metal block changed again.

Two square modules appear on the interface, namely: data loading and scientific and technological research and development.

The text is in Chinese language that Lu Chen knew.

Lu Chen's heart was beating and he quietly swallowed and spitted.

Then he stretched out his finger and clicked on the data loading.

The next moment, the display of the ferrous metal interface changed again:

a. Informatics: lv0(1/100)

The interface is quite simple, and there is nothing else.

But...how to return this?

This idea just came to Lu Chen's mind, and the interface immediately returned to the initial interface, namely the data loading and technology research and development module.

"In other words, the "Software Structure and Design Pattern" I just read is to load data on this black machine. So..."

Lu Chen's eyes moved to the data and loaded it into the technology research and development module below, and his breathing became more and more rapid.

Extend your finger and click gently on the technology research and development module.

Next second.

The interface changed again, and a white border appeared in front of Lu Chen. On the white border, there were three words "please edit".

Are you going to edit yourself in the white border?

Lu Chen frowned.

After pondering for a while, he immediately issued an instruction in his mind: "Program a calculator program."

Programming calculator programs is the first time Lu Chen took C language class. The teacher taught the mini program. It is also the first practice for many novices who are learning programming to get started with programming.

As Lu Chen's instructions were issued, changes suddenly occurred in the white border, and several words "Programming Calculator Program" appeared and disappeared.

But then, a line of text pops up in the white border, "The programming language is insufficient, should you continue programming?" followed by the two options "Yes" and "No".

Seeing this, Lu Chen vaguely understood the working principle of this ferrous metal block.

When loading data, it is loading knowledge, while when scientific and technological research and development, it is based on these theoretical knowledge.

Without theoretical knowledge, scientific and technological research and development will inevitably be greatly hindered. He is not clear about the specific performance, but it is nothing more than the failure of research and development or the unlimited extension of the research and development time.
