Crossover Anime: Edit everything, join the chat group

However, just when everyone thought the matter was over, Gu Chuan's next words were like a depth charge thrown into a calm lake, creating a huge uproar.

[Observer: Sorry, I was busy just now. While studying, I also improved this gem magic and created something new.]

The group chat fell into a deathly silence once again.

Everyone stared at the sentence on the screen, reading it over and over, wondering if they had misread it.

Improvement?

Did you create something new?

An ordinary person who has only been learning magic for half an hour has managed to improve a magic system that has been passed down for generations...?

After an unknown amount of time, a single word slowly and tremblingly appeared on the chat interface.

[Gem Magician: ...Huh?]

A New Theory of Observers (Part 4)

This single word seemed to have exhausted all of Rin Tohsaka's strength, and it also fully expressed her utterly absurd feelings at this moment.

She almost instinctively retorted.

[Jewel Magician: Impossible! Absolutely impossible! That's a magic crest perfected by generations of our Tohsaka family ancestors! It's the most effective theory, proven over hundreds of years! How could it be modified by an amateur... or even just an ordinary person who's only just started learning magic! You... you must be joking!]

Her words seemed somewhat incoherent, filled with a defense of her family's heritage and a resistance to the upheaval of her worldview.

Gu Chuan's response remained calm, yet carried an undeniable composure.

[Observer: Don't get excited. Your magic system is interesting, but it also has some fundamental flaws. The initial analysis consumed almost all of my inspiration points, but thankfully your purchase just now allowed me to recoup some of my losses. I've already put some of my findings up for sale.]

As soon as he finished speaking, a series of system notifications flooded the group chat.

[System notification: The Observer has added a new item, "Gem Magic: Circuit Optimization Theory."]

[System notification: The Observer has added a new item, "Gem Magic: Ether Absorption Technique."]

[System notification: The Observer has added a new item, "Gem Magic: The Principle of Conceptual Resonance."]

[Butterfly Dance: Huh? Mr. Newcomer is really available... Wait, what's the price?!]

Shinobu Kocho opened the shop and let out an incredulous exclamation.

[Butterfly Dance: Ms. Rin's "Basic Theory" costs 100 points, so why does every theory that Mr. Observer lists cost 300 points?]

This discovery stunned everyone.

The viewer will automatically judge the value, which means that each of the three "improvement" theories that Gu Chuan casually picked up is worth three times the value of the Tohsaka family's century-old heritage.

[Ice Queen: ...Interesting. A mere mortal, yet capable of creating things far exceeding the value of his own rank.]

Esdeath also became interested, her words carrying a hint of scrutiny.

At this moment, the most bewildered person was Rin Tohsaka. She stared dumbfounded at the three glaring "300"s in the shop, feeling as if her brain had been severely impacted.

[Jewel Magician: @Observer! Explain yourself! What makes you think you can make something three times more expensive than the Tohsaka family's century-old legacy?! The screening event's assessment is absolutely wrong!]

Rin's tone was full of resentment and anger, like a cat whose tail had been stepped on.

Faced with her questioning, Gu Chuan then slowly began to explain.

[Observer: I've identified three main problems with your theory. First, the circuit structure suffers from severe energy dissipation; second, it relies too heavily on expensive gems for energy; and third, its attack methods are limited.]

[Observer: Therefore, I proposed three directions for improvement. 'Structural optimization', reshaping the conduction model to improve energy efficiency; 'Energy openness', constructing a formula to draw 'ether' from the environment, allowing ordinary gems to be reused; 'Conceptual resonance', allowing lower-level gems to briefly unleash the power of higher-level gems.]

[Observer: The pricing for the screening is very fair, because each of these aspects is enough to fundamentally change your magic system.]

In the basement workshop of the Tohsaka residence in Fuyuki City, Rin's breath hitched as she looked at the three messages sent by Gu Chuan.

Structural optimization? Energy liberalization? Conceptual resonance?

Every word sounds like a fantasy, and every direction seems to be subverting the foundation of modern magic!

"It's a lie...it's absolutely a lie!"

Rin gritted her teeth, her competitive spirit and thirst for knowledge battling fiercely within her. "Fine, I'll spend all my points to buy your so-called 'theories'! I want to personally verify just what kind of nonsense this layman can spout!"

Almost out of spite, she used all her remaining points to buy three items that Gu Chuan had listed.

The moment the purchase was successful, three massive and intricate streams of information flooded into her mind.

Rin took a deep breath and decided to start with the most "realistic" approach—structural optimization.

She constructed the new circuit model proposed by Gu Chuan in her mind, and then activated her magic.

Instantly, an unprecedented sense of smoothness spread throughout his body! Magic surged forth like a flood bursting its banks, with almost zero loss!

“Gandr!”

A curse bullet, more solid and black than ever before, shot from her fingertips and slammed into the workshop wall.

"boom--!!!"

With a loud bang, the wall, which had been magically reinforced and was strong enough to withstand ordinary explosives, was blasted open with a hole the size of a fist, sending debris flying everywhere.

The power... is at least three times that of before! And the magic power consumption is less than half of what it was before!

Rin's small mouth opened slightly, and she was completely stunned.

[The Jewel Magician: Monster...]

She typed two words tremblingly in the group chat, then took a deep breath and turned her gaze to the second theory.

"Energy unlocking... allowing gemstones to be reused?" For her, who was obsessed with money, this was an irresistible temptation!

She took out an ordinary crystal from the drawer, which was not filled with any magic, and tried to draw "ether" from the surrounding atmosphere according to the spell given by Gu Chuan.

A wondrous thing happened: a faint but pure energy was drawn into the crystal, causing it to glow slightly.

"You really can! Do it again, Gandri!"

The same curse projectile was fired, though not as powerful as one using a high-grade gem, it was still successful! The crystal in her hand was only slightly dimmer, but completely undamaged!

[Jewel Magician: This...this has overturned the very foundation of magic! The Tohsaka family's finances...are saved!]

She excitedly posted a message in the group that left everyone scratching their heads, and then, with an almost reverent air, looked at the third theory.

"Conceptual resonance..."

Trembling, she picked up another, cheapest quartz stone, closed her eyes, and recalled the most perfect concept of "flame" she had ever seen. Following Gu Chuan's method, she tried to "resonate" this concept with the quartz stone.

There was no violent magical fluctuation, no dazzling light; the quartz stone merely trembled slightly before returning to its original state.

"Failed?"

Rin was a little confused. She aimed the quartz stone at the training alloy dummy and infused it with magic.

The next second, a torrent of flames, far hotter and more violent than when she used the ruby, erupted forth, instantly melting the alloy dummy into molten iron, which sizzled on the ground. The quartz stone in her hand, after releasing the flames, turned into a fine white powder.

They traded cheap products for a breakthrough that far exceeded their potential!

At this moment, Rin Tohsaka's mind went blank; all her pride, all her heritage, all her common sense were utterly shattered.

She slumped to the ground, opening the chat group in a daze.

[The Jewel Magician: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!]

A series of exclamation marks expressed her feelings that she could not describe in words at that moment.

[Ice Queen: ...What exactly happened?]

[Butterfly Dance: Miss Rin? Are you alright?]

[Sword Dao Shura: What exactly is that improvement?]

The curiosity in the group was completely ignited. Watching Rin's series of inappropriate reactions, they all tagged Gu Chuan, eager to know what kind of world-shaking new theory this mysterious observer had created.

The concept of 5-dimensional ascension (Part 1)

Fuyuki City, the underground workshop of Tohsaka House.

Time seemed to freeze at that moment. Rin Tohsaka slumped onto the cold stone ground, staring blankly at her slender fingertips that had just unleashed terrifying power, and at the molten alloy dummy in the distance.

Her mind, that self-proclaimed genius mind, filled with knowledge of the demonic path, was now blank, with only the ever-echoing exclamation mark representing ultimate shock remaining.

[The Jewel Magician: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!]

The string of symbols she sent in the chat group precisely conveyed her unspeakable emotions at that moment.

And within the [Cross-Dimensional Film Screening], this silent awe is also spreading.

[Ice Queen: ...What exactly happened?]

Esdeath's voice took on a serious tone for the first time. She could sense that, just a moment ago, the energy level that Rin unleashed had far exceeded the "mortal level."

[Butterfly Dance: Miss Rin? Are you alright?]

[Sword Dao Shura: What exactly is that improvement?]

Shinobu Kocho and Saeko Busujima showed their concern one after another.

They also noticed Rin's loss of composure and developed an unprecedented curiosity about the newcomer known as the "Observer."

What did he do to make a proud and talented magician lose control of his emotions to such an extent in just a few minutes?

Under the eager questioning of the group members, Rin seemed to regain her language skills.

She didn't reply to the group chat, but instead, in a trembling voice, she quietly recounted everything that had just happened. Her voice was soft, yet it struck everyone's heart like heavy hammer blows.

"...Three times the power, half the energy consumption...Ordinary crystals can actually draw magic from the atmosphere...And that quartz stone, it didn't rely on heat, but directly used the concept of 'flame' to 'melt' the alloy..."

After she explained the incredible phenomenon of "conceptual resonance," the group fell into a new, deeper silence once again.

If "structural optimization" and "energy openness" still fall under the category of "technological improvement," then "conceptual resonance" has completely exceeded their understanding.

[Sword Master Asura: Imbuing weapons with 'concepts'... In my world, this is a realm that only legendary sword saints can reach.]

[Butterfly Dance: This... isn't this the principle behind how the Nichirin Blade can slay demons? Because the blade itself is imbued with the concept of the 'sun'... he can actually artificially replicate this process?]

[Ice Queen: Transforming intangible concepts into tangible attacks. Hmph, interesting. This has already touched the threshold of 'laws'.]

Esdeath's tone had lost its contempt, replaced by a scrutinizing gaze as if she were facing a worthy opponent.

At this moment, everyone understood. What Gu Chuan presented was not a "reform theory" at all, but a complete, higher-dimensional power system.

They all turned their gaze to D, who had remained silent.

[Gem Magician: @Observer...how...how did you do that?]

Rin's voice no longer carried the questioning and resentment of before; it was now filled only with the purest thirst for unknown knowledge.

Faced with the intense gazes of everyone in the group, Gu Chuan finally broke his silence.

[Observer: As I've said before, your magic system is interesting, but it also has some fundamental flaws.]

His tone remained calm, as if he were stating a very simple fact.

[Observer: Rin, your gem magic, in essence, is doing one thing—using a battery (gem) to light a light bulb (spell). All your efforts are focused on finding a more powerful battery and making the light bulb emit brighter light. But you've never considered why you must use a battery? Why can't you just connect it to the power grid? And why can the light bulb only emit light and not heat or cool it?]

This analogy was simple and easy to understand, yet it sent a shiver down Rin Tohsaka's spine.

Electric grid? Heating? Cooling?

These words, like bolts of lightning, shattered the shackles of her preconceived notions.

Gu Chuan ignored her shock and continued his explanation.

[Observer: 'Structural optimization' simply means I corrected the wiring of your old circuit, reducing resistance, thus increasing energy transfer efficiency.]

[Observer: 'Energy Openness' means I've helped you bypass batteries and found a plug to connect to the 'grid' (ethereal environment), so you no longer have energy anxiety.]

[Observer: As for 'conceptual resonance'... I'm just telling you that besides emitting light, a light bulb can also simulate the effects of other electrical appliances by adjusting the frequency and properties of the current. This is the principle behind allowing a gem that can only 'store magic' to briefly simulate the concept of 'flame.' Of course, this kind of overload operation will greatly shorten the bulb's lifespan.]

Gu Chuan's explanation did not involve any profound magic theories. He simply used a more macro and essential perspective to clearly deconstruct Rin's proud magic system.

In the underground workshop of Fuyuki City, Rin Tohsaka listened in a daze, feeling as if she were not learning magic, but listening to a "technology lecture" from a higher civilization.

She got it.

What Gu Chuan did was not an improvement.

He upgraded her hand-cranked generator into a controlled nuclear fusion reactor.
