Tsinghua University, somewhere in a computer room.
The network administrator was about to go to sleep for a while, but unexpectedly, a confirmation notification message that the permissions had been modified suddenly popped up in the background.
His pupils suddenly shrank, and the sleepiness that had just surged was frightened away.
The network administrator moved the mouse pointer to the notification message interface. After clicking in, he found that the interface was blank.
He didn't give up.
His fingers quickly entered the log query command on the keyboard. What surprised him was that there was no relevant operation information in the log.
Very clean.
It's so clean that it's suspicious.
The network administrator looked solemn, opened the green software interface and sent a message to a certain account.
At this time, Jiang Chen didn't know that someone had discovered him.
The opening time of the Tsinghua University Library is at eight o'clock in the morning.
In order to go to the library early, he got up at five o'clock in the morning to communicate with Sun Shang, a cultivator of immortality, about the details of flint production.
It has to be said that after following Guo Fan's obsessive-compulsive disorder for a long time, Jiang Chen gradually had the illusion that he had to choose between "I'm a jerk" and "Everything must be perfect."
After finally communicating the details of the flint with Sun Shang, he took the excited prop members of Group B to find his father.
After arranging the work plan for the week, Jiang Chen took a bag of milk and drove the factory's Jinbei car to Qingdao University of Science and Technology.
When he successfully entered Qingdao University and arrived at the library, he discovered that the library door was not open yet.
Quarter past seven.
Came a little early.
When Jiang Chen was thinking about whether to go somewhere else, he didn't expect a yawning middle-aged man to walk up the steps of the library.
The middle-aged man was stunned when he saw Jiang Chen.
"It's not the end of the semester, why are you here so early?" The middle-aged man, affectionately called Lao Wu by the students, is the administrator of the Qingdao University Library.
"Old Wu, I need to check some information. If I come here early, I'll finish it early."
Old Wu looked him up and down, then opened the door and said, "Good boy, it looks like you are going to take the postgraduate entrance examination. Okay, you can come in first with me today."
Old Wu originally wanted to have a leisurely breakfast, but Jiang Chen's arrival completely disrupted his plan.
He couldn't eat any fragrant carbohydrates, so he could only eat thick noodles and suck a cup of soy milk.
He couldn't understand why he had to suffer the same crime when he came to the library after living in this kind of life at the institute.
Jiang Chen followed the information marked on the digital library and quickly found the three books he wanted in the library. After finding the books, he quietly picked a seat and started reading.
When Lao Wu saw the other party reading a book intently, he yawned again uncontrollably.
He didn't sleep well last night, which made Lao Wu feel tired.
When Lao Wu was considering whether to go to the lounge to take a rest, his cell phone rang by chance.
Buzz.
The phone vibrated twice.
Old Wu's face hardened, and he picked up his phone and took a look.
It was a message from the network administrator of Qingdao University of Science and Technology.
"Old Wu, have you found the intruder last night?"
Old Wu resisted the urge to curse and quickly replied with a message:
"Don't mention it. I don't know if the intruder got mad in the middle of the night last night. He didn't do anything and even helped us apply a patch to close the loophole."
"I've also seen the patch, and there's nothing wrong with it at all."
"Okay, I will continue to observe this matter, and you don't have to worry about it."
The whole thing is really outrageous.
I hacked into other people's systems in the middle of the night and patched them without doing anything.
What kind of new-age good guy is this?
Old Wu felt that he couldn't understand people nowadays more and more.
The time came to nine o'clock.
Lao Wu found an angle to take a picture of work that he thought was perfect and sent it to his friends. He also sent a message saying: "See, my working environment is very comfortable now!"
After sending the photo, Lao Wu did not look at his phone again because he knew that his friend would not reply to him.
But it has become Lao Wu's habit to send photos to each other every day.
It doesn't matter whether the other party replies or not.
Lao Wu, who was idle and bored, shifted his gaze to Jiang Chen.
There were not many people in the entire library. Jiang Chen had been sitting there reading like a very hard-working student.
It's been almost two hours, and this kid is not sleepy at all while reading. He doesn't know what he is reading.
Old Wu passed by Jiang Chen while pouring water. When his eyes glanced at the book in Jiang Chen's hand, his breathing became faster.
It’s actually a book about exoskeletons.
Is this guy studying exoskeletons?
Lao Wu felt itchy in his heart and couldn't help but asked: "Young man, are you studying exoskeletons?"
Jiang Chen was looking at it seriously. He didn't expect that Old Wu would talk to him. He hesitated for a few seconds before replying: "That's right, I might need it recently."
He thought that Old Wu would leave immediately after being so perfunctory, but he didn't expect that the other party sat down. His eyes were full of curiosity, and he didn't even notice that Jiang Chen continued to ask:
"Are you going to use it recently? Are you preparing to write a paper?"
Jiang Chen shook his head and simply said: "It's a practical exercise, but I plan to use it as a prop."
In order to avoid arousing suspicion, Jiang Chen only mentioned that he was making props and did not say that he was making real objects.
But what made Jiang Chen feel strange was that when Old Wu heard that he was making props, the light in Lao Wu's eyes dimmed a lot.
"Ah, just making props."
"Indeed, our Dragon Kingdom has not paid much attention to this research yet. You, a college student, must be doing it for fun."
“But it’s always a good thing that young people are starting to study it.”
Old Wu's expression was melancholy, which made Jiang Chen feel that Old Wu seemed to know something about exoskeletons.
At that moment, Jiang Chen tentatively said: "However, some knowledge points here are too difficult to understand. For example, I don't understand how to increase the user's mobility while locking the joints of the whole body."
Lao Wu shook his head, thinking that if you figured it out, you wouldn't be sitting here. However, he still answered patiently: "At present, it is basically impossible to achieve. What you are doing should be an unpowered exoskeleton, right?"
"Everyone who is just getting started starts with an unpowered exoskeleton. You don't have to think so much when making a prop. It's much harder to increase the feasibility of activities than you think."
"What's more, you have to consider two basic issues: high durability and long battery life, so it's good to learn the basic structure."
"Come on, young man."
As if something sad happened to him, Old Wu waved his hand, picked up the tea cup and left.
Want to build a flexible exoskeleton that locks joints throughout the body?
Lao Wu suppressed his inability to calm down and repeatedly told himself that it was just a dream.
Can a student build an exoskeleton? What a bullshit joke this is!
