One Proof, Eternal Proof

"Hoo—"

A mournful, chilling wind mixed with the low hum of electronic equipment jolted Xu Feng awake from the gloom.

He sat up from the bed, only then realizing he had fallen asleep without even knowing it.

As expected, textbooks were the best sleeping pills.

He rose and looked toward Xiao Dan's desk, where a faint, cold light still emanated.

The little one was scribbling away at her homework.

The light from the desk lamp swayed gently.

It cast the shadows of the objects in the room against the wall, making them look like bared fangs and brandished claws.

Xu Feng touched the cold alloy bedsheet, feeling a sense of unease.

The scene was somewhat heartwarming, yet simultaneously absurd.

"Clack—"

"Tap—"

The alloy door knocked against the doorframe intermittently, producing a heavy, peculiar sound.

Xu Feng glanced at the little girl as she turned her head: "Keep studying."

With that, he climbed out of bed by the light and walked toward the door.

Reaching the doorway, he looked closely and realized the mechanical structure of the door lock was broken.

"What rotten luck."

He muttered to himself as he reached toward the alloy door.

However.

At that very moment.

A wet, dripping arm suddenly lunged in from outside.

It grabbed onto the edge of the alloy door!

The hand appeared suddenly and eerily, but Xu Feng's reaction was lightning-fast.

In a split second.

Without the slightest hesitation, Xu Feng lifted his leg and kicked the alloy door with all his might!

The movement was swift and decisive!

"Bang!"

The alloy door slammed heavily against the doorframe.

The arm instantly retracted!

The next moment, a shrill scream erupted from outside: "Ah! Xu Feng! What the hell are you doing?!"

Inside the room, both Xu Feng and Xiao Dan were startled.

Immediately after, amidst the cold wind.

A slender figure shoved the door open and stormed into the room, clutching her arm and glaring at Xu Feng: "Are you trying to get yourself killed?!"

Only then did Xu Feng see the person's face, and he frowned, saying coldly: "Don't you know how to knock?

Do you have any idea how many people have died around here lately? Who wouldn't be scared by you acting like that?"

"Oh? You're actually acting righteous now! You're not usually like this, are you?"

As the woman spoke, she casually took off her outer cloak, revealing a figure that was curvaceous yet clearly possessed great explosive power.

A look of surprise crossed her face as she looked at Xu Feng.

Xu Feng immediately fell silent.

While scrutinizing the woman's ample chest, he frowned: "Since it was a misunderstanding, should I rub it for you?"

The woman rolled her eyes, ignoring him completely.

She then closed the door, turned, and walked toward Xiao Dan with her long legs, a sincere smile appearing on her face: "Have you finished your homework?"

"Sister Lu, I finished it a long time ago!"

Xiao Dan happily stood up and hugged the woman, who lifted her up and let her hang from her neck.

"Did that dog treat you badly today?" Lu Fei whispered into Xiao Dan's ear.

"No, Dad seems to be sick," Xiao Dan replied in a low voice.

Watching the two of them whispering intimately, Xu Feng stood far away by the door, not daring to approach.

Because this woman's identity was far from ordinary.

Lu Fei.

A graduate martial artist from Sky Moon Martial University.

It was said that her strength was not weak, her talent was not poor, and she held a high status throughout the entire garrison zone.

Yet, this "three-no" female student had met Xiao Dan through a volunteer teaching program.

Since then, she had been running over to their place every few days.

Of course.

This woman was certainly not coming for Xu Feng.

As a forty-year-old slovenly uncle with a slightly pudgy physique, Xu Feng was very clear about his current "social status."

After chatting with Xiao Dan for a while, Lu Fei turned to look at Xu Feng, a flash of disgust and coldness in her eyes: "I came to find you today because there's a job. See if you'll take it."

"Not taking it."

However, Xu Feng didn't even think about it and refused point-blank.

In his memory, most of the jobs this woman introduced involved people dying.

Lu Fei glanced at the messy room and sighed.

She turned and walked to the table nearby, picked up a water cup, mixed in a packet of unknown powder, and handed it to Xiao Dan.

"What is that?" Xu Feng stood up alertly, but didn't dare to approach.

Lu Fei glanced at him: "Nutrient supplement. What, you can't afford it and haven't even seen it before?"

Xu Feng's lips twitched. If I had seen it, would I be asking you?

Graduate students' brains aren't that great either.

It must be from practicing martial arts.

"This job is different from the previous ones. Are you sure you won't take it? The exploration team organized the day before yesterday has returned.

There are indeed rare plant essences in the spirit cave along the Red Water River, but two members of the Golden Wing Clan are also hiding there.

The exploration team suffered heavy losses, many corpses haven't been dealt with, and some plant essences still remain in the spirit cave.

If you're willing to go, I can recommend you to carry the corpses.

Three thousand yuan a day. If you're lucky, you might even find a plant essence, which is worth hundreds of thousands—"

Before Lu Fei could finish, Xu Feng shook his head and decisively interrupted: "Not taking it. I haven't lived enough yet."

"Tch, with your pathetic state, living so miserably, you might as well be dead." Lu Fei said, making no effort to hide her disappointment.

As she spoke, she ruffled the little one's hair.

"I'm leaving."

Immediately, Lu Fei put on her coat and turned to look at Xu Feng: "Right, I'll warn you one more time. If you hit Xiao Dan again, I'll tear your arms off."

She looked coldly at Xu Feng's arm again.

Then, she revealed her own arm.

The spot that had just been heavily pinched by the alloy door.

There wasn't even a red mark; she was as strong as a beast.

"If you don't believe me, you can try it."

After saying that, Lu Fei pushed the door open, stepped into the cold wind, and vanished.

"Tch, big chest, no brain."

Xu Feng muttered, completely unbothered by her threat.

As for the job she mentioned, he didn't even need to think about it.

If it were truly a good job, those with "connections" would have snatched it up long ago.

Would it ever be his turn?

"Dad, Sister Lu is actually quite smart, she's just a bit of a romantic fool."

Xiao Dan whispered.

Xu Feng rolled his eyes and turned to pinch the little girl's chubby face:

"At your age, you know what a romantic fool is? Time for bed."

"Oh."

Xiao Dan pouted, got up, and obediently went to wash up.

Having sent away the female plague, Xu Feng blocked the door with a table.

He then turned back to the table, sat down, and sighed: "Phew, let's keep reading. Fortunately, there's still something left in my brain; I should be able to digest it soon."

Soon.

Xiao Dan finished washing up and silently went to bed.

Xu Feng pulled the bed curtain he had handmade two days ago shut for her.

Only then did he sit at the desk and begin to study his books in earnest.

Three-plus hours later.

Xu Feng set down Antenna Principles for 100G Mobile Terminals and Fundamentals and Repair Techniques for Micro-Crystalline Energy Circuits.

He then carefully compared the damaged communicator at hand against the schematic in the Small Communication Bracelet Repair Manual.

Rubbing his temples, he tiptoed over to retrieve his repair kit and began the practical work.

"It's a good thing I'm dealing with this most basic type of communicator; if it were one of those mid-to-high-tier smart bracelets, I'd be completely helpless."

He muttered to himself, beginning to tinker under the magnifying glass.

Repairing such micro-devices was a task that required immense patience and meticulousness.

Furthermore, one had to have a steady hand.

Although he had advanced repair kits that far exceeded those of his past life to assist him, it was still a massive undertaking for Xu Feng.

Fortunately, he was a science and engineering student with decent grades who had worked at several telecommunications companies.

Whether it was mobile phone antennas, vehicle antennas, or radio frequency engineering, he had some experience.

Even though there was a massive gap between the technological levels of his past life and this world.

At least he had the knowledge stored in the original owner's brain to serve as a foundation.

Soon, Xu Feng managed to finish the first communicator with great difficulty.

He glanced at the sky; it was already turning gray outside, nearing daybreak.

The day-night cycle in Dimension 13 was similar to that of Earth.

Therefore, Xu Feng was particularly hopeful that his night of hard work would yield results.

Taking a deep breath, he pressed the power button with a heart full of trepidation.

"Beep—Welcome to Weihua Technology. The communication device is resetting. Self-test complete. We wish you a pleasant life!"

Xu Feng waved his arm in excitement, only to slam it against the corner of the table with a loud "bang."

"Hiss—"

He sucked in a breath of cold air from the pain, tucked his hand between his legs, and hopped silently, gritting his teeth to keep from making a sound.

He glanced at Xiao Dan, who was still fast asleep.

Xu Feng walked to the bedside, baring his teeth as he took a few deep breaths.

His face was twisted.

He was filled with both joy and pain.

After a long while.

He finally recovered and turned his gaze back to the communicator in his hand.

But just then, he suddenly froze.

He saw several neat lines of text appear before his eyes:

[Name: Xu Feng]

[Blood Qi: 172c]

[Age: 40]

[Skills:

Nine-Star Body Refining Art [Free Version] · Proficient (29/100)

Communicator Repair · Novice (1/5)]

Xu Feng: "(ω)!???"

Just as he was in a daze, the text quietly vanished.

Xu Feng stood stunned for a moment, then sat on the bed with a heart full of faint excitement and a single thought.

The text panel reappeared.

After trying to open and close it several times, Xu Feng finally confirmed that his eyes were not deceiving him, nor had he gone mad.

As for the age of forty on the panel, he skipped over it entirely.

Although he was a dozen years older, old was old.

His physical fitness was still stronger than when he was young and robust in his past life.

He could lift hundreds of pounds of cargo whenever he wanted.

The point was the significance of those last two lines of text.

To verify that his guess was correct.

Xu Feng returned to the table and picked up another damaged communicator.

This time, he cultivated until the first light of dawn.

Xu Feng stretched his back and powered on the second communicator to run a self-test.

"Welcome to Weihua Technology. Communication device is resetting."

A surge of excitement stirred in Xu Feng's heart.

Those few lines of the text panel emerged once again.

[Skills:

Nine-Star Body Refining Art [Free Version] · Proficient (29/100)

Communicator Repair · Novice (2/5)]

This repair was clearly much smoother than the last one. So the numbers really do change accordingly; is this what they call proficiency? Does that mean if I repair three more, I'll reach the next level? From novice to proficient? That seems reasonable enough.

Xu Feng let out a sharp sigh of relief and collapsed onto the bed.

He shouldn't starve to death in this world, right?

At the very least, he now possessed a survival skill he could rely on.

Compared to others, his progress was always visible.

Furthermore, this kind of data would never regress.

Isn't this what they call "attaining once, attaining forever"?

"Time to sleep!"

It felt as if a massive boulder had been lifted from Xu Feng's heart, and he finally relaxed completely.

For a moment, his vision blurred and his heart hammered against his ribs; he couldn't tell if it was from excitement or the onset of sudden death from sleep deprivation.

Regardless, he was snoring less than two minutes after his head hit the pillow.
