Chapter 216: End of the Training Camp

“You’re too close, ah, ah…”

“What’s wrong, I helped you for half the day, can’t I even give you a kiss?”

Lei Dongchuan put his words into action, kissing the instep of his foot again. Seeing him delicately curl up his toes, trying hard to hide, he couldn’t help but smile a bit.

Lei Dongchuan wanted to do something even worse.

Just as he reached his hand down, Bai Zimu dodged him, furrowing his brows and saying:

“Don’t, you just wiped the desk, you didn’t wash your hands.”

Lei Dongchuan pressed the tip of his nose against his, saying in a hoarse voice:

“How come from childhood to adulthood, you have so many issues, alright alright alright, I won’t use my hands, I’ll use something else, okay?”

Bai Zimu was stunned for a moment, and then saw him slide down, caught off guard he cried out:

“Brother!”

……

After a long time.

By Lei Dongchuan’s ear it quieted down, the ankle wearing the gold bracelet rested on one side of his shoulder, looking as if it was about to slip off, having no strength left; the faint sound of gold bells that had been ringing one after another just now returned to tranquility.

Bai Zimu was unbearably tired, he had been tugging at Lei Dongchuan’s hair just now, telling him to get up, but it was to no avail. He waited until his brother was fully satisfied, before letting him go.

Lei Dongchuan leaned over, giving his forehead a kiss.

Bai Zimu recovered for a moment, raising his eyes to look at him, hazy with a watery mist.

He hadn’t yet snapped back from the clouds and mists of just now, when he saw Lei Dongchuan swallow something down. He hurriedly reached out to touch him, but couldn’t stop him, feeling somewhat exasperated for a moment:

“Brother, how could you eat that… so dirty!”

“Not dirty.”

Lei Dongchuan coaxed him to sleep, covering him with a thin quilt:

“You sleep for a while, I’ll watch the time, and wait half an hour before calling you up to eat.”

Bai Zimu had been tossed about for a bit, and was also tired. Covered by the quilt, he snuggled up next to him and fell asleep.

Lei Dongchuan looked down at him, his fingers twirling his hair in circles. [Read on RanaTranslations🌸] Only when the person fell asleep, did he slowly get out of bed to clean himself up.

Perhaps having released his pressure, Bai Zimu slept very soundly this time, recovering much better than a usual hour of sleep. When he woke up he laid there lazily; even though he was awake it was still very comfortable, even his fingertips felt relaxed, not wanting to move.

Lei Dongchuan had already heated up the food once. When Bai Zimu got up to eat, he sat to the side peeling an apple, slicing it up and placing it in a small porcelain plate before handing it to him:

“Eat this too in a bit.”

Bai Zimu:

“I can’t finish it.”

“Just try a bit, I’ll eat the rest.”

Bai Zimu looked at him, his gaze slowly shifting downwards again. Lei Dongchuan fed him a piece of apple, faintly carrying a bit of warning as he said:

“Don’t provoke me, my internal heat is high these two days.”

Bai Zimu smiled a bit, leaning in closer to whisper in his ear, saying a sentence in a low voice.

Lei Dongchuan hesitated for a moment, but still shook his head:

“Forget it, wait until later.”

Bai Zimu found it strange:

“Why, Brother, I can also help you—”

The little bit of fire Lei Dongchuan had just suppressed was almost provoked by him again. He raised his hand and flicked him on the forehead,

“I’m not the same as you, even adding your eating time you only have half an hour left, what is this little bit of time enough to do?”

Bai Zimu was unhappy, talking back to him:

“Then are you saying I’m fast? [Read on RanaTranslations🌸] I’ve already tried very hard, who told your strength to be so great!”

Lei Dongchuan: “…”

Lei Dongchuan:

“Eat quickly, go to the laboratory after you finish eating, hurry up and finish that broken ‘training camp’, next time you talk to me like this again, see how I deal with you. Also, next time you are not allowed to sleep in the laboratory, you must pay attention to your health in the future, it’s not yours alone.”

“Then whose is it?”

“Mine.”

Bai Zimu was teased by him to the point of continuously laughing, still not having detected the danger.

When he finished eating, took a bite of the apple and wanted to leave, Lei Dongchuan simply grabbed the person over, burying his head at his collar, his Adam’s apple moving slightly. Holding back his teeth that wanted to bite down, he only held that small piece of tender flesh in his mouth and ground it with his teeth. Bai Zimu was startled, and that piece of apple in his hand fell to the ground.

Lei Dongchuan threatened:

“What did I just tell you? If I catch you being a picky eater again, I’ll punish you.”

Bai Zimu’s fingers gripped a bit tighter at his shoulder, his body tensed up, softly calling his name.

Lei Dongchuan let him go.

Bai Zimu didn’t leave, but instead hugged him, hiding in his embrace.

Lei Dongchuan just hugged him like this, saying in a hoarse voice:

“Did I scare you?”

Bai Zimu shook his head, only after a while saying:

“A little bit.”

“There will be many things like this in the future, and even more excessive things will be done, if you can’t bear it you can still stop now—”

“Brother, I know.”

Lei Dongchuan paused for a moment, approaching his ear, speaking in a low voice.

Bai Zimu was initially still listening, but very quickly his face was burning hot, the side of his ears red almost to the point of dripping blood. He covered Lei Dongchuan’s mouth, raising his head to glare at him.

Lei Dongchuan raised an eyebrow:

“Didn’t you know everything, if you knew why are you afraid of me saying it?”

Bai Zimu:

“Then you also can’t… also can’t, say everything!”

Lei Dongchuan grasped his wrist, lowered his head to kiss it, laughing softly without stopping.

Bai Zimu used his head to bump him once, annoyed at his impudence. After a moment he felt something wrong beneath him, wanting to get up, but was held down by Lei Dongchuan, hugging him a bit tighter as he said:

“Don’t go, just let me hug you like this for a while, won’t do anything to you.”

“Brother, I should still get up, how are you going to go out later like this…”

Lei Dongchuan hugged him and muttered:

“Right now I don’t want to go out at all, can’t we just sit here for a day.”

Bai Zimu tugged at his hair, smilingly making him get up:

“What do you want to do? From then on the Emperor did not hold early court?”

“Can I?”

“You cannot!

Professor Tang gave Bai Zimu a year’s time, Bai Zimu was faster than he anticipated, finishing several months ahead of schedule, rushing to hand in a perfect answer sheet at the end of August.

Professor Tang Yin personally came to Jingda, observing the calculation program once again in the machine room.

This time the path was correct, and the calculation was extremely rapid.

Bai Zimu’s under-eyes carried dark blue circles, wearing the same white lab coat as everyone else in the laboratory, sitting in front of the computer, his line of sight unblinkingly stared at the screen with rolling numbers.

Behind him were several academicians, as well as the seniors in the “training camp group” who had struggled together for more than two years of time.

All the mathematical models he constructed, hundreds of equations, were all deduced by hand one by one, completely solving the contradiction between the computer’s calculation path and the equations.

Within the nearly perfect calculations, the originally rock-solid MD5 was pried open with a small gap.

The progress that had stagnated for several months previously, at this moment, finally calculated new data, once again pushing a large step forward. Some students had already begun to be unable to hold back from wanting to voice out cheers, but the calculation was still ongoing, so they could only suppress their excited emotions, trying hard to press their hands against their hearts, awaiting the next most anticipated result.

Bai Zimu said calmly:

“Teacher, the calculation is complete.”

Professor Tang Qi suppressed his somewhat trembling voice, trying his best to calmly say:

“Switch to a standard computer, and proceed with the second deduction.”

“Yes.”

After using the new algorithm, the standard computer only calculated for a little over two hours, before effortlessly cracking the M Country military’s security system.

Professor Tang Qi glanced at his wristwatch, instructing the students to make proper records. He somewhat couldn’t suppress his own excitement, saying emotionally:

“Right now it is 2 hours, I believe there are definitely personnel familiar with computers present, if this result is used more reasonably and optimally, the cracking time in practical applications will be elevated yet again compared to this.”

The other academicians standing on the side also nodded one after another, many people’s faces revealing smiles:

“Although our Huaguo’s computer science is just starting out, there are quite a few talents on the network, there are definitely experts like this!”

“Right right, the important significance of this deduction lies in proving that the distribution of Hash values has obvious patterns, this breaks the previous experimental data in theory, greatly lowering the difficulty of attack!”

……

Everything in the world, there is no making without breaking.

Since they could crack it, then they could create a more reasonable cryptographic system.

All things are difficult at the beginning, they had already walked past the most difficult step, every step from here on out, would be filled with confidence.

From the old professors with greying temples to every single young student, everyone couldn’t control their eyes from somewhat brimming with hot tears. Professor Tang Qi took off his glasses and wiped the hot tears from the corner of his eyes, sighing:

“Good, too good, this first step of the long march of ten thousand li, we have finally stepped out.”

A professor from the Jingda Mathematics Academy to the side smiled and shook his head, saying to him:

“Elder Tang, these words of yours aren’t right, how is it just stepping out one step, this is already walking halfway. You also shouldn’t leave, just stay here and apply to participate in the global cryptography conference, when the time comes the moment this scientific research result is published, the ones who should be anxious and getting angry, will be the M Country people!”

Professor Tang Qi smiled and nodded:

“Yes, we have been anxious for so many years, it’s time to let them also be anxious for a bit.”

There was still a period of time away from the global cryptography conference. After Professor Tang filed an application with the higher-ups, he planned to personally write this paper, and selected the students to bring abroad to participate in the conference.

He had three capable students under him, two males and one female, among which was Bai Zimu.

It was just that when finding Bai Zimu, Bai Zimu actually shook his head and refused.

Professor Tang Qi was somewhat surprised, and asked:

“Zimu, what’s wrong, your deduction ability is obvious to everyone, this is the honor you deserve.”

Bai Zimu smiled and said:

“Teacher, you and Senior Sister Wang Yun, and the senior brothers have been busy for these few years, I merely joined at the very end, doing very little; furthermore, I have already obtained the reward that belongs to me.”

Professor Tang Qi was somewhat doubtful, saying uncomprehendingly:

“What reward?”

Bai Zimu said:

“The people from the Eleventh Bureau told me, they have already found some news regarding my dad, I plan to go into Tibet to take a look after finishing the advancement exams at the beginning of next month.”

Professor Tang Qi sighed, saying to him:

“You are a good child, after finishing looking for the person this time, what are your plans?”

Bai Zimu carried a few fractions of pride as he said:

“Of course it’s to continue cracking, although MD5 has already been overcome, behind it there is still SHA-1. Teacher, I have the confidence, and also the certainty to complete this cracking, for next year’s global cryptography conference, I will take you and Senior Sister to go over together.”

That little bit of melancholy in Professor Tang Qi’s heart, was instantly dispersed into thin air by him. He patted his shoulder and laughed:

“You brat, so it turns out you looked down on MD5, holding in an ultimate move here? That is a result just researched abroad in the past two years, claiming to be a password that even ten supercomputers would take a hundred years to calculate. If you really can crack SHA-1, don’t be my graduate student anymore either, when the time comes I will help you apply, go to the Academy of Sciences, when you have free time just come over and guide my graduate students for me and that will do!”

Bai Zimu thought for a moment, and asked:

“Teacher, how is the salary at S University?”

“You really want to come?”

“Mn, the people in my family are all in Lu Province, after I graduate I also plan to go back.”

Bai Zimu truly felt that a university teacher was not a bad job. First, he liked the simple academic environment of the school, and second, there were winter and summer vacations, adding up to being able to rest for a very long time, it couldn’t be more suitable for him.

Professor Tang Qi had never thought there would be this kind of unexpected pleasant surprise, repeatedly saying:

“You graduate in peace, do well the cracking work on hand, the future matters, Teacher will help you arrange.”
