Dormitory group chat, my information updated daily.

An hour later, on the first floor of the Truth Bookstore.

Little Huotou buried his face in Su Muqing's arms and cried loudly.

"Mmm... (Mommy, Daddy is a bad person...)"

Feeling her eldest son trembling with grievance in her arms, Su Muqing looked at Xiao Yun, her beautiful eyes filled with coldness.

"Ahem, Su Su, let me explain."

"Stop grinning and kneel down properly."

Su Muqing snorted coldly and raised her staff, smashing it down on Xiao Yun's head.

"Bloodletting? Xiaolong is your own son, how could you do that?"

"Cough cough cough, I also needed it urgently, so I had no choice but to resort to this tactic, and I only released a tiny bit."

Xiao Yun weakly made a gesture, preparing to brush it off.

Just then, Gu Shen, that bastard, suddenly appeared out of nowhere and said in a low voice:

"Hehe, Ah Yun, you look honest and quiet, but you're actually a black-hearted, cunning old fox. Sister Su, you don't know, do you? Back in high school..."

As Gu Shen spoke, he suddenly paused, looked at Xiao Yun, and a slight smile appeared on his lips, revealing a hint of schadenfreude in his eyes.

Wow!

Cold sweat instantly broke out on Xiao Yun's forehead.

"Damn! How did this bastard come here just by smelling the scent?"

In the guild channel and in the small group chat with Ji Mingyu and others, Xiao Yun's "request for support" signal was worn out.

At the main entrance, Ji Mingyu and the others acted as if they hadn't seen anything, keeping their eyes down and not bothering to join in.

How can outsiders like them interfere in other people's family affairs?

Moreover, opportunities to see President Xiao suffer setbacks are rare.

"Born! They're all born!"

Xiao Yun roared inwardly, raised his eyes, and looked at Liu Lingling standing next to Su Muqing.

"Lingling is so kind, she'll definitely speak up for me."

Seeing Xiao Yun's pleading gaze, Liu Lingling tilted her head, revealing her small white teeth, a sly glint in her eyes.

"Sister Su Su, Brother Fire Dragon says it's in so much pain, it feels like it's going to die... Waaah, Brother Fire Dragon is so pitiful."

Liu Lingling, with her small body, clung to the little fire dragon's arm, her big eyes glistening with tears.

In an instant, a chilling killing intent erupted from Su Muqing, almost freezing Xiao Yun into an ice sculpture.

"That's it, this is completely hopeless..."

Xiao Yun gave a bitter laugh, then gave up and lay sprawled on the ground.

"Hurry up and give me a quick death."

"snort!"

Su Muqing let out a cold snort, and glittering ice crystals condensed on her staff. With a swing of her arm, she slammed the staff down hard towards Xiao Yun.

"Sister Su has it under control, brothers, let's go!"

Gu Shen let out a roar and led the crowd to rush forward, instantly joining the group.

A wail erupted, and the entire Truth Bookstore was filled with a joyful atmosphere.

Five minutes later, a group of people left the Truth Bookstore with their arms around each other and smiles on their faces.

Perhaps because of the perfect team fight, even Ji Mingyu's hostility towards Gu Shen lessened considerably, and the atmosphere became very harmonious.

"Hiss...a bunch of bastards, they went way too far."

Xiao Yun grimaced, his head swollen like a pig's head, and glared at them fiercely.

"What are you muttering about?"

Upon hearing Su Muqing's voice, Xiao Yun's expression changed instantly:

"Hehe, I said you did a good job. Look how much my son and I resemble each other now."

Su Muqing glanced at the several large bumps piled up on Xiao Yun's head, suppressed a smile, and turned her head away:

"Since you're so sensible, we'll leave it at that for now. You go ahead with your work, but don't forget to bleed a little to heal the little fire dragon."

"Yes, sir!"

Xiao Yun nodded hurriedly.

Su Muqing left with the little fire dragon and Lingling. Xiao Yun stood up and sighed softly.

"Now look what's happened, we have to give up 10 liters of blood. I should have just used my own, but..."

Xiao Yun glanced at the system panel, and a skill called [Candle Dragon] came into view.

"Thanks to Charmander's pure dragon blood, I'm not sure I could have fused such a good skill with my own."

As Xiao Yun's highest-ranking A-level skill, the effect of [Candle Dragon] is surprisingly simple—

Wide-range control + extremely high true damage, up to 20% execute damage - ignores all defense, invincibility, and death-prevention effects below A- grade, including talent, skill, and equipment effects.

Moreover, the special effects are even cooler than Junyan's.

"Aside from the final self-destruct of Eternal Blood, this is currently the skill with the highest damage output that I have."

With the added boost from [Harmony of Heaven and Man], Xiao Yun felt that even twenty Qi Huimings combined might not be able to withstand a single blow.

"Getting beaten up in exchange for an A-level skill, this is a huge win."

Xiao Yun grinned, which aggravated his injuries.

After gasping in pain, Xiao Yun's eyes instantly turned crimson gold, and a thunderous roar resounded from his chest.

Thump! Thump! Thump!

[Dragon Heart] roared, and beneath his skin, the blood vessels radiated red light, flames rose up, and the scorching heat swept through the entire Truth Bookstore.

Amidst the swirling flames, the effects on Xiao Yun's body rapidly subsided.

"Okay, all done."

Looking at his still handsome face in the mirror, Xiao Yun nodded.

At the control panel, Jiang Shangzhen nodded as well:

"Now that you've recovered, let's get back to work."

As he spoke, he tossed a pile of documents to Xiao Yun and said:

"This is what I just compiled. Follow my steps to derive these formulas first, and then work with me to build the first version of the mechanical model where magic replaces electricity."

"It's still early today. We need to do at least a few rounds of experiments and update a few versions in the remaining time. Ideally, we should be able to build a usable Unit-01 today."

OK.

Xiao Yun quickly entered a state of intense research.

Having advanced to the eighth sequence and benefited from the [Primordial Path to Godhood], his intelligence attribute has reached an absurd level. Coupled with the bonus from [Harmony of Heaven and Man], it wouldn't be an exaggeration to call him a humanoid computer.

The ideas, data, and alchemical terminology provided by Jiang Shangzhen were not as obscure and difficult to understand as before; in fact, they seemed somewhat easy to him.

"Teacher, could this part be changed like this?"

"Let me see, hmm, it does work."

Jiang Shangzhen glanced at his student and nodded in satisfaction.

But before he could turn his head, Xiao Yun came closer again.

"Teacher, is there a problem with this part? I think it would be better if we adjusted it like this."

"Uh, yes, that's true. Could you help me revise it? I was in a bit of a rush, so I probably didn't think of that at the time."

Jiang Shangzhen smacked his lips, looked at Xiao Yun, and suddenly felt something was wrong.

As expected, very quickly.

"Teacher, could you please check the formula I derived?"

Jiang Shangzhen nodded stiffly, took the draft paper, and looked at the various mathematical symbols on the paper with a somewhat blank expression.

"I'm sorry, teacher, I forgot to tell you. Because the magic system is quite different from our original electromagnetic system, I created a few symbols for convenience. Let me explain them to you first."

As Xiao Yun explained, Jiang Shangzhen's eyes became even more bewildered.

Suddenly, he remembered the equation he had solved when he became a disciple of Confucius: "An equation about a satellite launched from Earth, orbiting the Sun, and returning to Earth."

That equation was very difficult. It was said to be an exam question set by Confucius's teacher. Among Confucius and the students who took the exam that year, only two were able to solve it on the spot.

But he solved it.

More than a decade later, after achieving great success, he looked at the derivation formulas written by his students and found that he couldn't understand them at all!

My master's famous words echoed in my ears:

Even the dumbest person can learn calculus, right?

Jiang Shangzhen once used this phrase to tease many people, but now, when he thinks of it again, he suddenly feels a deep sense of powerlessness.

"Could it be that I'm an idiot too?"

Jiang Shangzhen began to doubt himself, and his Dao heart almost shattered.

Just then, Xiao Yun patted him on the shoulder.

"Teacher, teacher, have you finished reading?"

Jiang Shangzhen snapped back to reality, looked at Xiao Yun, and a fleeting look of melancholy crossed her eyes:

"Xiao Yun, you are... ready to graduate."

Xiao Yun was taken aback, but quickly understood the situation.

"Haha, teacher, I'm only benefiting from your higher rank. Compared to your research expertise, I'm still far behind."

"That makes some sense, but in scientific research, if it's not good, it's not good; there's no room for fraud."

Jiang Shangzhen smiled, his earlier dejection quickly disappearing:

"Since you have this ability, you will lead this research, and I will assist you."

Xiao Yun exclaimed "Oh dear!" and quickly waved his hand:

"Teacher, please don't joke around. How can you break the rules just to advance the research?"

Jiang Shangzhen remained silent, only taking a sip of tea and quietly meeting his gaze.

A few minutes later, both master and apprentice couldn't hold back and their lips curled up slightly.

Xiao Yun stopped pretending and waved his hand dismissively:

"Alright, it's just beginner level anyway. I'll handle it this time, and you can take over the more difficult ones when you advance."

Jiang Shangzhen nodded and, without further ado, laid out all his research findings.

As the research progressed and the workload gradually increased, Xiao Yun and Jiang Shangzhen brought their materials to the research institute on the South Campus and called on all the alchemists to work together on the research.

Seeing that Xiao Yun was in charge of this research, some senior scholars were somewhat dismissive.

They admit that Xiao Yun is very strong, but what does he know about this kind of research?
