Dormitory group chat, my information updated daily.

On the blade of the mithril sword, pieces of ore melted and dissolved in water.

Soon, Xiao Yun's dozen or so precious ores were all used up.

As the last small piece of mithril was swallowed by the mithril sword, wisps of light appeared and circled around the sword.

[Transformation] has been activated, and a transformation is underway.

Clang clang!

More than ten minutes later, the mithril sword trembled and emitted a joyful sound, spreading out a sharp and powerful aura.

Xiao Yun's eyes lit up. He beckoned, and the mithril sword in the air emitted a light sword hum, transforming into a streak of light that landed steadily in his palm.

Stroking the blade of the mithril sword, feeling the faint connection emanating from it, Xiao Yun's lips curled into a slight smile.

"Its spirituality has become stronger. If we continue to nurture it, it won't be long before it truly develops a spirit."

Unfortunately, the Mithril Sword still did not advance to B+ grade.

Just then, the Mithril Sword sent a message.

Xiao Yun suddenly understood.

"Do you need a weapon similar to the [Bronze Short Sword] or the [Useless Rusty Iron Sword]?"

Xiao Yun pondered for a moment and then used the system to search.

[In the Eternal Empire, Xu Shanhai, the Grand Commander of the Tiger Army, possesses a blood-stained scimitar. It was made from the flesh and blood of heroes slaughtered by the goblin chieftain and can be used to enhance the mithril sword.]

"So they've gotten involved with the Eternal Empire again...?"

Xiao Yun frowned slightly.

At this stage, he does not actually want to have a direct conflict with the Eternal Empire, let alone with the previous Grand Commander who was at least in the eighth rank.

Countless thoughts arose in Xiao Yun's mind, only to vanish in the blink of an eye.

"The storm of reality and illusion is still raging. Even if I wanted to, I'd have to wait until the storm has passed."

By then, Zhong Mo, Kong Changhao, and others will have all been promoted to the eighth sequence, so it's not like they can't be touched.

Putting the matter aside for the time being, Xiao Yun turned and left the work area, waving to Gu Shen:

"I'm gone."

"Uh-huh."

Gu Shen nodded, stuffed half an egg pancake into his mouth, picked up another one, and followed Xiao Yun with half a cup of soy milk.

"Look at the way you're eating, how come you didn't choke to death?"

Xiao Yun said irritably, snatching the egg pancake from his hand.

Gu Shen looked annoyed, but because his strength hadn't recovered, he couldn't compete with Xiao Yun at all.

"Tsk, you little brat, just you wait. Once I surpass you in strength, you'll be in for a world of hurt."

"Heh, shut up, you little bastard."

"You son of a bitch..."

Accompanied by birdsong and the fragrance of flowers, the two arrived at the [Truth Bookstore].

Xiao Yun stretched out his oily hands, wiped them on Gu Shen's clothes, and then pushed open the door.

In the dim light, rows of bookshelves stood like giants, with only a few bookshelves in the very center piled with scattered books, while the others were empty.

Surrounded by bookshelves, an alchemy workbench was set up in the open space. A small shelf next to it was labeled with various materials and instruments, which were neatly categorized.

"Tsk tsk tsk, so Teacher Jiang is actually... cough cough, such a respectable alchemist is a rare sight."

Gu Shen sighed in surprise.

Xiao Yun gave him a strange look:

"The teacher has always been very tidy, why do you say that?"

"Ah, it's nothing. It's just that most alchemists are busy with various research projects and rarely clean their alchemy rooms... Well, just take it as a stereotype."

Gu Shen said calmly, bowing slightly to greet Jiang Shangzhen:

"Hello, Teacher Jiang."

At the control panel, Jiang Shangzhen nodded slightly and said:

"Yeah, Xiao Yun's childhood friend, right? Don't be shy, come on, I just happen to need someone to discuss this with."

As he spoke, he waved a stack of yellowed pages in his hand.

Xiao Yun and Gu Shen's eyes lit up at the same time.

"Books refreshed today? That's fast."

Xiao Yun strode up, took it from Jiang Shangzhen, glanced at it, and suddenly frowned.

"The Epic of Ilandes, it's a B- grade, which is quite high, but it's just a poem praising a legend, and it's incomplete, so it's not very valuable."

Xiao Yun shook his head in disappointment and handed the book to Gu Shen.

"Ilandes, I can't believe I saw him here..."

Gu Shen murmured softly, a complex light flickering in his eyes.

Xiao Yun is right. As things stand, this incomplete book has no value.

However, if you collect ten fragments to complete the book, you can use it to summon the legendary hero to serve you.

"This is one of the most famous books in the Truth Bookstore. Ah Yun is so lucky."

Gu Shen sighed inwardly, silently finished reading, and returned "The Epic of Ilandes" to Jiang Shangzhen.

"Value is hard to define, and although it's an epic, there really are extraordinary things in this world. Maybe we can find some useful information out of it."

Jiang Shangzhen took it, took out a box, and carefully put the book inside.

Then, he picked up a book and handed it to Xiao Yun.

"Here, take a look at this book; you should be interested."

The Use of Magic - Elementary Level

Explore different genres of science fiction; there's bound to be one that suits your taste.

Upon seeing the book cover, Xiao Yun's eyes lit up, and he quickly flipped through it.

The book's explanation of the use of magic is not for combat, but for everyday life.

Mana can be converted into energy, into signals, or even into reality...

Xiao Yun saw the possibility of using magic to replace electricity, electromagnetic waves, and even oil.

In an instant, he became completely absorbed in the book, his eyes sparkling with dazzling light, occasionally letting out exclamations and muttering to himself.

"This guy, still the same..."

Gu Shen shook his head and chuckled, but he wasn't interested in the book. He looked around the entire Truth Bookstore while chatting with Jiang Shangzhen.

After chatting for a while, Jiang Shangzhen was surprised to find that Xiao Yun's childhood friend, the newly appointed vice president of Ideal Country, had an astonishing amount of knowledge.

"Besides, why do I feel like this guy knows me so well? Is it just my imagination?"

A hint of doubt flashed in Jiang Shangzhen's eyes. He glanced at Xiao Yun, then relaxed.

"Xiao Yun thinks there's no problem, so why am I worrying? Maybe he has a unique talent for communicating with strangers."

Gu Shen observed Jiang Shangzhen discreetly, sighing inwardly:

"It's not easy to poach A-Yun's teacher, but... Teacher Jiang's personality at this time is also different from what I remember."

Gu Shen's eyes flickered slightly, a hint of curiosity rising in his heart.

What exactly happened to transform the refined and easygoing Jiang Shangzhen in front of us into the obsessive, stubborn, and crazy person we remember?

"Ah Yun's life has truly changed a lot of things..."

Gu Shen glanced at Xiao Yun, his feelings incredibly complicated.

Meanwhile, Xiao Yun had also finished reading all the content.

"Alas, it's a pity. It's only beginner level. The various methods were only explained in general terms, not completely. The energy conversion formulas, various recipes, and the manufacture of tools all need to be explored little by little..."

Xiao Yun closed the book and sighed softly.

"As long as you have a direction, that's fine. Your teacher isn't someone to be trifled with either. After receiving the book yesterday, I already had a few ideas."

Jiang Shangzhen said with a smile, and Xiao Yun nodded vigorously, exclaiming that his teacher was awesome.

"Teacher, you can go ahead and do your work with confidence. I've recently made a small fortune, and I have plenty of resources."

As he spoke, Xiao Yun took out the items he had traded with Yue Liang and the others the night before from his backpack and placed them in front of Jiang Shangzhen.

"Huh, so many ores, not bad, not bad, just right... Did this core drop from monsters? I've never seen it before, and there's this kind of item that controls swarms of insects... Where did you get so many odds and ends?"

"Haha, by sheer coincidence, I got it from a secret vault in Happiness Lane."

Upon hearing Xiao Yun's explanation, not only Gu Shen, who could tell the origin of these things at a glance, but even Jiang Shangzhen didn't believe his nonsense.

These things clearly come from different regions, otherwise Jiang Shangzhen would have seen them before.

"You little rascal, you're not being honest... By the way, why haven't you given me the paper you mentioned last time? How many days has it been?"

Jiang Shangzhen's face tightened, and an unspoken sense of oppression swept over him.

Gu Shen quickly dodged to the side, fearing that he would be covered in blood in a moment.

"Oops... Oh no, I forgot about the ball."

Xiao Yun gasped inwardly, then quickly smiled apologetically and promised to finish it in the next two days.

Jiang Shangzhen gave him a half-smile, knowing his student's character, and waved his hand:

"Forget it, I know you're unreliable. I already handed that project over to Qin Siyu, so don't bother with it. Just help me research the use of magic these next few days; you should be familiar with that."

Xiao Yun felt as if he had been granted a pardon and promised Jiang Shangzhen that he would definitely complete the mission.

Seeing that Xiao Yunlai had other matters to attend to at the Truth Bookstore, Jiang Shangzhen waved his hand and went to study the prerequisite theories himself, letting him do whatever he wanted.

Xiao Yun didn't waste any time. He pushed a ladder over from the side, called Gu Shen, and climbed to the top of the bookshelf.

buzzing-

An invisible wave spread out, and a hazy light rose up.

The bookshelves beneath my feet were arranged in an orderly fashion, forming a huge rune array.

In the center of the rune array, an altar woven from countless runes appeared, with an illusory book floating in the center.

[Ding! The True Knowledge Codex has been activated. Currently, you can choose to create/fuse/improve... skills/equipment characteristics/material special properties...]

[3/3 usage attempts remaining today]

"With my current knowledge, creation is out of the question. I simply can't create any skills above C+ level. Improvement would be pointless. Fusion, on the other hand, is something I can try, and it can also streamline the skills I have."

Xiao Yun looked at [Fusion], his eyes gleaming.

Just as he was about to start trying, Gu Shen suddenly blocked his way.

What are you doing?

"I want to use it too."

"What are you even doing, you haven't even changed jobs yet!"

"Never mind that, I need it anyway. Move aside, I'll be quick."

"This is outrageous! How dare you, a vice president, compete with the president? Get out of the way, I'll let you take a look at it for a couple of seconds."

"Alright, alright, is that how you play it? I'll go tell Su Muqing right now that you didn't celebrate her birthday in high school because you were actually on a date with a younger female student!"

"Bullshit! You're slandering me!"

"Heh, whether it's slander or not isn't up to you to decide."

"...Gu Shennima!"
