Chapter 99

He looked into Tang Lingwu's dark circles and gently furrowed his brow, asking softly, "What time did you sleep last night?"

He suspected that this girl had stayed up late working on something.

Tang Lingwu didn’t respond, merely waved her hand at him, flicked her ponytail, and swayed over to her seat—then she simply laid her head down on the desk and began to doze off.

"What’s this?"

Wang Chen had quietly approached Zheng Fa, curiosity piqued as he pointed at the symbols in the notebook.

"…It’s hard for me to explain," Zheng Fa thought for a moment before replying.

"…" Wang Chen stroked his chin, glancing between Zheng Fa and Tang Lingwu, a look of realization dawning on his face: "It’s you two, isn’t it?"

"?"

Wang Chen clapped Zheng Fa on the shoulder, a hint of envy in his voice: "A top student is still a top student, even when it comes to dating!"

Zheng Fa looked at the animated Wang Chen, feeling that the guy had conjured up something extraordinary in his mind: "What are you talking about?"

"I’ve watched too many spy dramas! Is that a codebook?" Wang Chen pointed at the notebook in Zheng Fa's hand. "Are you two doing encrypted communication now?"

"…You’re overthinking it." Zheng Fa stared at Wang Chen, baffled by his thought process.

At that moment, a head with a built-in spotlight peeked out from behind Wang Chen.

Wang Chen’s face turned pale as he saw Lao Chen glance at him, then shift his gaze to the notebook.

"Let me see that."

Lao Chen reached out toward Zheng Fa.

He examined the densely packed symbols, stroked his chin, then looked at Zheng Fa and Tang Lingwu, a flicker of realization crossing his face…

Zheng Fa felt like he had seen that expression just moments ago.

Lao Chen didn’t say anything to Zheng Fa but placed the notebook in front of him, giving him a meaningful look.

Watching Lao Chen walk away, Wang Chen patted Zheng Fa’s shoulder and asked, "Do you think Lao Chen is overthinking it?"

"…"

At Bai Laotou's house.

Upon hearing that Tang Lingwu had discovered a structure related to gold, Bai Laotou couldn’t help but glance at her in surprise.

"It seems quite right."

After verifying the gold-related symbols categorized by Senior Sister Zhang, Bai Laotou nodded.

Zheng Fa glanced at Tang Lingwu.

She still looked quite tired, but a relieved smile had appeared on her face.

Bai Laotou seemed to notice her expression and turned to give Zheng Fa a deep look.

Zheng Fa nodded gently.

On the other end of the computer, Han Xiaobai was also modifying the algorithm.

Once they knew what to look for, things became much simpler.

An hour later, the five structures representing metal, wood, water, fire, and earth appeared vividly on the screen.

They tried using these to find the structure of yin and yang, only to discover that yin and yang seemed to differ from the five elements—at least this approach didn’t yield results.

Zheng Fa randomly dragged the five patterns in the software, shifting their positions and orientations, as if piecing something together.

"What are you doing?"

Zheng Fa remained silent, focused on the screen, slowly manipulating the patterns.

"Got it!"

Suddenly, the five structures on the computer screen formed a cohesive whole.

Earth connected to metal, metal to water, water to wood, wood to fire, and fire to earth.

"Hmm?"

Bai Laotou was taken aback, staring at the computer screen.

"You thought this was a whole from the beginning?"

"No, I got the inspiration from the symbols within me."

Today, he had specifically observed the upright shadowless symbol and the frost blade symbol condensed in his dantian; these two had been adjacent since their formation.

Today he realized—those adjacent parts represented the structures of "earth" and "water," and they combined to form a new pattern.

This led him to speculate whether these five structures could interconnect.

"Are these five things actually one?" Bai Laotou frowned.

Zheng Fa nodded, opened his notebook, and wrote a simple sentence: "The five-element attributes of a symbol are determined by a specific structure, which can be called a five-element sub-symbol; five-element sub-symbols can combine to form a whole."

Bai Laotou stared at the line of text for a moment, then burst into laughter: "You’re trying to write a law, aren’t you?"

It seemed he had caught a glimpse of Zheng Fa's hidden ambition.

Zheng Fa shook his head: "It still needs verification, but once it’s proven, I want to name it this."

He wrote eight characters above that line.

"Bai Family Symbolism First Law."

"Ah?" Bai Laotou pointed at himself: "You’re naming it after me?"

"The biggest credit goes to you," Zheng Fa said with a smile.

"Ahem, this is the collective wisdom of the three of us, collective wisdom."

"Then should I change the name?" Zheng Fa pretended to want to modify it.

"Forget it, that name sounds pretty good!" Bai Laotou quickly stopped Zheng Fa, staring at the line of text and grinning for a long time, suddenly feeling a bit emotional: "Having done math my whole life without leaving a mark, if there really is such a law, I’d die without regrets."

It sounded like he didn’t take it too seriously.

**Chapter 112: Repair**

The Bai Family Symbolism First Law might only bring a smile to Bai Laotou now, but the "Five Thunder Method" left him speechless.

At Zheng Fa's home.

Bai Laotou, still fixated on his dream of electromagnetic rotation and punching stars, came over out of curiosity when he heard Zheng Fa was going to practice the "Five Thunder Method" at home.

Tang Lingwu followed along.

Bai Laotou looked around, a hint of confusion in his voice: "Do you usually practice at home?"

"Why not?"

"I’ve read novels where they rely on rare treasures or at least find a waterfall to train…"

"I do have a treasure," Zheng Fa thought for a moment and nodded.

"What is it?" Bai Laotou's face lit up with excitement.

Zheng Fa pointed to the corner of the room.

Bai Laotou looked at the plain, unassuming transformer sitting on the floor, even noticing that the label was still brand new, his expression momentarily blank.

"Practicing immortality… is it this down-to-earth?"

Bai Laotou smacked his lips, a hint of disappointment on his face.

Zheng Fa felt he was missing the gold inlaid with jade.

His transformer was a thunderous treasure upgraded!

He had added two metal clips to the exposed copper wires, which, when strapped to his wrist, pressed against his skin, making it look like he was wearing wrist guards.

Previously, when he practiced, he had to hold the wires, shaking as he trained.

If anyone saw him, they’d think he was an electrician who had accidentally electrocuted himself.

Now it looked much more presentable.

Zheng Fa plugged in the transformer, set the voltage to 90V, then sat back in his chair, strapped on the clips, and crossed his legs.

Bai Laotou and Tang Lingwu watched as his arm twitched, their expressions filled with concern.

But since Zheng Fa was in training, they didn’t dare speak, only breathing quietly as they closely observed him.

"Tang Lingwu, can you help me with something?"

Zheng Fa suddenly opened his eyes and spoke to Tang Lingwu.

"Sure! I’ll turn it off!" Tang Lingwu, thinking Zheng Fa couldn’t handle it, rushed over to the transformer to switch it off.

"No, can you just turn the voltage up a notch?"

"Up?"

"Yeah, I’m about to reach the next level in the 'Five Thunder Method.'" Zheng Fa’s eyes sparkled with excitement: "The current voltage isn’t enough."

Tang Lingwu bit her lip, cautiously turning the voltage knob to the right, the needle now pointing at 120V.

Zheng Fa’s brow furrowed slightly, the veins on the back of his hand pulsing.

Clearly, the increased current was making his body a bit uncomfortable.

Bai Laotou and Tang Lingwu held their breath, intently watching Zheng Fa’s condition.

After a while, Zheng Fa opened his eyes again.

"Shall I turn it off?"

Tang Lingwu asked again.

"Turn it up one more notch!"

This time, Tang Lingwu hesitated more, her hand hovering over the knob as she looked back at Zheng Fa, seemingly seeking confirmation.

Zheng Fa nodded gently.

Click.

"Turn it up more!"

…Click.

"More!"

The knob was turned to the 210V setting.

Zheng Fa’s face clearly showed signs of pain.

Especially as his muscles began to react—twitching from his arms to shoulders, even to his chest, back, and thighs, muscles bulging and then disappearing.

To Bai Laotou and Tang Lingwu, it looked like dozens of little mice were scurrying beneath his skin.

What reassured them slightly was that Zheng Fa’s pain seemed temporary.

After about ten minutes, he appeared to adapt, though the little mice were still running around, his brow gradually relaxing.
