Fission

Are you ready?

"Ready."

Are you really ready?

"... Xiao Jiu, it's just about increasing the age of a Soul Ring, isn't it? Instead of questioning me, why don't you just take action?"

"Hey, we have to go through the procedures, right? If you hadn't been so weak when you were little, you wouldn't have survived even a thousand years. I wouldn't be doing this for you."

"Alright, alright, hurry up."

In the sea of the mind, that moon revolves steadily and brightly.

Xiao Jiu lay beneath the moon, its nine tails curling it into a ball, but its eyes were open, gazing at the moon, its pupils reflecting the moonlight.

"Enter a meditative state, it will be quick."

"OK."

In Yun Jingheng's room, he sat quietly cross-legged on the bed, his body emitting faint fluorescent light.

Five Soul Ring surrounded him, and the color of the two purple Soul Ring grew increasingly dark.

Yun Jingheng opened his eyes, stretched, and his joints made a slight cracking sound.

He got out of bed, stretched his neck, and looked down at the Soul Ring at his feet—four black and one red.

Wow, this setup is enough to scare a lot of people.

He put away the Soul Ring and walked to the small blackboard in the corner of the room.

The blackboard was covered with densely packed formulas.

He looked at it for a while, picked up the blackboard eraser and wiped off a few strokes, then added a few more with chalk. He took a step back, tilted his head, looked at it, nodded, and then shook his head.

He sighed, turned around, walked to the table, and began tidying up the things on it.

Drawings, pens, and rulers were piled haphazardly on the table.

The door was suddenly pushed open.

The door slammed against the wall and bounced back. Ye Xinglan stood in the doorway, her high golden ponytail swaying, a hint of anxiety on her face.

Gu Yue stood behind her, her expression curious, but her gaze went past Ye Xinglan's shoulder and landed on the room.

Yun Jingheng paused for a moment, then subconsciously turned his body slightly towards the blackboard, blocking part of it with his body.

His movements were natural, as if unintentional, but Gu Yue's eyes narrowed slightly.

What is E=mc²?

"Why are you here? And couldn't you at least knock?"

Yun Jingheng's voice sounded somewhat helpless.

Ye Xinglan ignored him, walked in, and stood by the table.

"You haven't been to class in a long time, I came to see you."

Her gaze swept around the room, finally settling on Yun Jingheng's face.

Are you alright?

Yun Jingheng shook his head, "It's nothing, I'm already level 57."

"What the hell?!"

Yun Jingheng took half a step back, bracing himself against the edge of the table.

"What the hell are you yelling about?"

When did this girl become so loud?

"What kind of Soul Spirit did you absorb? Even after 100,000 years, it shouldn't suddenly increase your level by 7!"

Yun Jingheng's brow twitched, and his gaze shifted unnaturally to Gu Yue, who had a half-smile on her face.

"... I absorbed a Hundred Thousand Year Soul Ring and Soul Bone, not Soul Spirit..."

"Hundred Thousand Year Soul Ring? Did your dad get it for you?"

Yun Jingheng nodded, "Mm."

Ye Xinglan took a deep breath, "When did your physique become so good? Was that towering pillar of light a few days ago because you were absorbing Hundred Thousand Year Soul Ring?"

"If no one else is absorbing it, then it must be me."

Ye Xinglan turned to look at Gu Yue, "Do you believe me?"

"He believes it, and he doesn't seem to be lying."

Ye Xinglan's lips twitched. "You believe that again?"

Gu Yue nodded, "Yes, and why did you say 'again'?"

Ye Xinglan rolled her eyes and gave Yun Jingheng a defiant look. "Gu Yue is looking for you. I'm leaving."

???

"Huh? You're leaving already?"

"I've gone to cultivate."

Yun Jingheng stood at the door watching Ye Xinglan walk further and further away, then slowly turned back to look at Gu Yue, preparing to ask her why she had come to see him.

Gu Yue stood right behind him.

He was so close that he could see the curve of her eyelashes.

His pupils contracted slightly, and his body instinctively leaned back, his back hitting the door frame with a dull thud.

His breath hitched, and his heart seemed to skip a beat.

"Why... are you standing so close?" Yun Jingheng's voice was a little dry.

Gu Yue looked at him without saying a word.

She smiled. "What are you afraid of?"

Yun Jingheng rubbed his head. "What's there to be afraid of?"

Gu Yue glanced at him. "Then why are you leaning back?"

Yun Jingheng paused for a moment, then said, "... A conditioned reflex."

Gu Yue didn't ask any more questions. He turned around and walked to the small blackboard, looking at the formulas.

Yun Jingheng's heart tightened. He forced himself to remain calm and leaned against the door frame, his hands in his pockets, watching Gu Yue's back.

Her hair fell over her shoulders, the ends slightly curled, swaying gently as she tilted her head.

The mass-energy equivalence equation, the fission formula, the critical mass formula... she probably wouldn't understand any of that...

Gu Yue's gaze slowly swept over them, his expression growing increasingly confused.

E=mc²,²³⁵U+n→¹⁴¹Ba+⁹²Kr+3n+200Mev, Mc=2π²λ_ᶠMa/Nᴬ·σ_ᶠ...

"What are all these things...?"

"Just some random scribbling and drawing."

Gu Yue turned around and looked him up and down.

Yun Jingheng stood there, hands in his pockets, his expression unusually calm. At this moment, he was Wu Zhangkong.

But his heart was beating fast...

Gu Yue stared at him for a long time, then took a step forward.

Yun Jingheng didn't back down; he simply chose to stick his back against the door frame.

Gu Yue took another step forward, getting very close to him, so close that she had to look up to see his eyes clearly.

She looked up at him, a smile playing on her lips.

"Uncle-Master~" Her voice was soft, with a hint of amused laughter.

"You're being naughty."

Yun Jingheng's Adam's apple bobbed.

Wc--!

"What did you do wrong?"

Gu Yue tilted her head and looked at him.

"Lie."

"I don't."

"Then look me in the eye when you speak."

Yun Jingheng took a deep breath and looked down into Gu Yue's eyes.

Those were very deep eyes, dark brown, like autumn soil, like aged tea, like a chestnut shell thoroughly baked by the sun.

His face was reflected in her pupils, so clearly that he could see the crescent moon mark between his brows reflected in her eyes.

Her eyelashes were long and slightly curled, casting a small fan-shaped shadow on her eyelids.

Her eyes were clear and clean, without a trace of bloodshot, like freshly washed white jade.

When she looked at him, there was an indescribable light in her eyes, something he had never seen in anyone else's eyes.

Haha, is this how you test your cadres?

... I'm sorry, I'm a chubby girl.

Gu Yue looked at him, the curve of her lips remained unchanged, but the light in her eyes shifted.

Her eyelashes trembled slightly, then she smiled, a smile that held a hint of smugness, a hint of understanding, and something else entirely indescribable.

"I'm not teasing you anymore," Gu Yue said.

"So what exactly do you want from me?" Yun Jingheng asked.

"Tang Wulin's Battle Armor is finished, now... shall we make yours?"

Yun Jingheng thought for a moment, then gently shook his head.

"Do it your way, and as for whose it is, you can discuss it."

"Why? You're already Soul King, aren't you?"

"Yes, but I haven't decided what materials to use."

"Alright, I'll be going now. Remember to come to the secret training tomorrow. That's what Tang Wulin asked me to tell you."

"Good."

Yun Jingheng stood at the door, watching her figure disappear, and stood there for a while.

This world has oxygen and hydrogen, so... what about uranium?
