Bit Mania [Hacking]

Ge Zheng lay on the table curiously, looked at the white plastic jar in front of him, shook it in his hand, and there was a rustling sound of particles shaking inside.

"Wow……"

A hand stretched out from the side, took the jar in front of him, and put it into a small cardboard box next to it. There were already various large and small plastic jars in the box. Zixin repacked the box and held it. He raised his hand to make sure it wouldn't fall apart, so he found a chair and sat down.

"...Where do you get so many health products?" Ge Zheng scratched his face.

"I bought it." His youngest junior brother looked serious, "I don't know what the teacher needs to make up for, so I bought some of each."

"Ah,..." Ge Zheng was about to ask another question, but saw that his teacher had already come out of the study, and there were Mr. Mu and Yao Yizhi beside him.

Zixin walked over with the cardboard box in one hand and grabbed Song Yubai's sleeve with the other. The three of them stopped and looked at him suspiciously.

"Xiao Xin, what's the matter?" Song Yubai asked with a smile.

The boy opened his mouth, but hesitated to speak. Just when everyone was surprised, his eyes suddenly turned so red, against his fair face, he looked like a wronged little white rabbit.

It was originally the most beloved treasure of everyone in the Song family. After being tied with someone like Yao Yizhi yesterday, an adverbial was added to become "the scariest treasure". Such an existence that no one would ignore suddenly appeared like this In the abnormal situation, a sentence suddenly appeared in everyone's head - the atomic bomb exploded!

The three people who were at the core of the explosion froze, Song Yubai opened his mouth wide, and didn't know where to put his hands. The old man who was once a master in the academic field stood there at a loss like a fool.

"Teacher... this is for you to eat on the way... I will come to see you..." The boy lowered his head and whispered, handing a box full of health care products to Lao Song.

"Oh... thanks!... eh?!"

"Yesterday I was really bad," Zixin said guiltily, "I couldn't get a score on any random impromptu test question. Teacher, you are about to be arrested and taken to the capital...but I will not give up..."

Song Yubai was dumbfounded: "Huh?!"

Yao Yizhi's eyes darkened: "Impromptu exam questions... bad... tie... bad... barely... bad..."

The expression on Old Man Mu's face became as if he was trying to endure something: "That's all bluffing..."

"what?!"

Mu Yun couldn't help being stared at by the child's big eyes. He rubbed his nose and glanced wildly: "Cough...we just want to touch the bottom of old man Song...ah, we wanted to kill his prestige... "

Yao Yizhi shook his head, and added from the sidelines: "...This matter is a contribution after all... You know, the Internet project was originally expected to be completed in the next three years, but I didn't expect this to be the first place to realize it... ...what we're going to do is not kill it, but expand it across the country..."

"Computing Institute, Engineering Research Center, University of Science and Technology of China...as long as we old fellows are still around, they can still help out. In addition, Lao Song himself has made outstanding achievements in the past. something..."

"Fuck...something?" Zixin repeated in a low voice, picked up the cardboard box, turned around and left.

"Ah, ah! Where are you going! What about the health care products you gave me..."

"Take it back and fertilize the bunches of cucumbers and corn in my yard!"

"Uh... how about that, give it to me, Xiao Xin..." Lao Song shouted bitterly after him.

Zixin looked back at the other party inexplicably, loosened his hand, Song Yubai's heart rang an alarm, he subconsciously stopped, and with a "bang", the carton containing health care products fell heavily on the ground only two centimeters away from his toes. The place.

He shrank his feet, feeling that his toes were really hurting. Seeing the child clapping his hands and about to walk out of the gate, a figure suddenly appeared from the side and grabbed Zixin's hand.

Ge Zheng shouted: "I caught him!"

Song Yubai quickly walked a few steps, hugged the person tightly, and said "baji" according to that face.

"Ah!" Zixin yelled angrily, covering his face.

"Aiya," old man Mu walked to the side at some point, squatted on the ground and opened the cardboard box, tsk-tsk as he flipped through it, "...Yansheng Protecting Liquid? Wow, he is really willing to spend money. , could it be that I bought this for you with all the pocket money I have saved all the time... But Lao Song, this is something to invigorate the kidney and strengthen the yang, you..."

"Make up your head!" Lao Song snatched the bottles in his hand, one in each hand, tightly protecting the child and the carton in his arms.

"Tsk, it's like a treasure, my apprentices respect me more than you..." Mu Yun grinned, seeing that his old friend didn't even bother him, and followed unwillingly.

"... Received such an apprentice, the blessings of several lifetimes have been exhausted by you old bastard..."

"Speaking of which, regarding this matter, I still need to learn more about your WAN design, to see if it can be used in the capital, so we can go back and do business..."

"Used in the capital?"

"Well, after all, Huanjiang Town is just a small place, not suitable for installing large servers, so we still need to move the center of gravity of our network back to the capital..."

"I don't agree!" Zixin was still angry because of what happened just now, and his face was still flushed with embarrassment: "Come with me, and I will tell you how good we are together..."

"……what?"

As he said that, he took out a stack of white A3 papers and a plane map of Huaguo, and began to draw on it. As the chief engineer, the network topology of Huanjiang Town could be easily memorized. On the paper, Zixin did not stop writing, and took out a brand new piece of white paper, and spliced ​​it on the left side of the Huanjiang Town design drawing. The two drawings were side by side, and the lines were drawn from one paper to the other. It actually connected the university towns in the nearby suburbs into this network system.

Mu Yao stood by and watched, sniffing.

After the university city was incorporated into the system, the boy took out three more blank sheets of paper, one was put together on the left side of the university city, and the other two were put on top and bottom of this one. In his hand, the long wooden triangle ruler is like a revolver in the hands of a cowboy in the gold rush era. It is constantly rotating under the skillful manipulation of fingers, and the angle is changing. The criss-crossing blue lines appear on the white paper. After drawing an area, he put down the triangular ruler and added annotations to the design drawing, so that the functions and specifications of these lines became clear at a glance.

The network structure of the entire Quhai City showed a rudimentary form. Zixin opened the Huaguo map on the side and began to expand to the whole province and even surrounding cities.

"Hey, I want to say, shouldn't the network topology be tree-like or bus-type...how can I draw it according to the map..."

"What you're talking about is the virtual structure. What I'm drawing here is the physical structure, which is the distribution and connection of switches, optical fibers, and servers. It has nothing to do with those routes..."

"...None, nothing to do?!"

"Yes." Zixin drew without raising his head, "Because you can use any virtual transmission method you want at that time, it's just a program, and I won't go into the small details here."

Even Song Yubai's eyes widened now.

There were not enough A3 papers on the table, so Zixin moved them to the floor. The wooden floor of Song Yubai’s house was always cleaned by part-time workers. Although it was not spotless, it was enough to roll on it. When they arrived one after another, what they saw was the scene of three old and one young lying on the ground in a pile.

"Let's stop here. The latter is actually the same reason. It can be clearly seen from these pictures that it is better to set up an Internet exchange switchboard in the bustling coastal city belt where Huanjiang Town is located than to install it in the capital. Much more...you have to learn to understand by analogy, understand?"

"Got it, got it! Can we take these papers?"

"It's just a draft, take it."

"..." Yao Yizhi lay on the ground, put together the network topology design diagrams of the Greater China region on the ground one by one with an empty face, carefully folded them, put them in an alloy file box, set three passwords, and proposed Second thing.

"By the way, Mr. Song, that matter...how do you think about it?"

"This kind of thing... depends on Xiao Xin's own opinion." Song Yubai turned to look at his youngest student: "Do you... want to go to Beijing to study in university?"

And here, Zixin had already talked to those senior brothers and sisters for a long time.

"...Fooling them to install a national server to our side, are you sure you are not taking revenge for what happened just now?"

"Look at my sincere face, am I this kind of person!"

Hearing what the teacher said, everyone turned their heads in unison, a little stunned.

"...How old am I?" Xiaoxin pointed to herself.

"There's something called the Junior Class—an existence specially set up for little perverts like you." Yao Yizhi said.
