[Physical Network]

"Yes!" Lein replied.

There was no need to hesitate.

He didn't know if he'd ever become a "Principal" and shout, "The advantage is mine."

He had transmigrated anyway, and this damned world was full of crises. Seizing any opportunity to strengthen himself was crucial for survival.

Those who don't climb will have to find a nice, scenic spot to be buried, where grass can grow on their graves.

Lein had no idea how exaggerated the scene was to others when he silently activated the campus network.

At that moment, the entire Vulture Dragon Mountain seemed to tremble. Even with the naked eye, one could see the four elements—earth, water, fire, and wind—condensing into threads of elemental energy.

These threads quickly became dense.

Earth's black.

Water's blue.

Fire's yellow.

Wind's gray.

The entire valley was bathed in the light of these four colors, representing power and mystery.

These elemental threads formed a very regular network, perfectly embedded into the valley along the mountain's terrain.

The entire process of light flickering might have lasted less than 5 seconds, but Downs deeply realized that the valley, which remained outwardly unchanged, had actually become a terrifying magical fortress, no different from a Mage Tower.

While shocked and moved by Master's incredible power, Downs's mind raised another question: Why didn't Master create this elemental network back then? Didn't mages always like to build Mage Towers?

Lein stood with his back to his disciple, hands clasped behind him, head tilted slightly, eyes closed peacefully, feeling the mountain breeze caress his face, letting the wind rustle his hair and the hem of his robes.

His serene and transcendent posture inexplicably made Downs feel the urge to worship him again.

If I want to worship, then I will!

Such a great Master deserved all the respect.

"Downs."

"Disciple is here," Downs replied respectfully.

"I am not from this world," Lein blurted out on impulse.

Downs bowed deeply. "For a hundred years, there have been no mages on the entire Chaos Continent. Master is not from this world, disciple... guessed as much. Disciple only knows that Master is good to me and possesses supreme wisdom. That is enough. As for whether Master comes from the heavens, hell, or the abyss, disciple does not care."

No, your grandpa here is from Earth.

But the words caught in Lein's throat. He glanced at Downs's bright, clear eyes—his good disciple clearly meant, Master, if you don't want to say it, you don't have to. You don't need to lie to me.

And so, the fact that Lein wasn't from any other plane in this universe was somewhat absurdly glossed over.

Lein suddenly sighed, deciding to bury the secret of his transmigration deep within his heart. "I originally thought that the 'Science' I taught you might not be accepted by this world. I didn't expect the world to recognize them as its laws. Since you've also grown to this point, let's go with the flow and bring some magic, as you see it, to this world."

"Yes," Downs became excited. He realized he would be a witness to a brand new legendary story!

"As the saying goes, 'One generation plants the trees, another enjoys the shade.' Some things must be done by someone. Since fate guided you to obtain a 'Magic Web Fragment,' it means heaven wishes for you to help rebuild the magic net, bring the light of magic to humanity, and secure a place for humans to survive. Therefore, this magic network, which I have named 'Physical Network,' should also be infused with magic by you."

Downs's breathing quickened.

Every word from Master was filled with profound meaning. Since Master, with his supreme wisdom, was guiding humanity to rebuild magical civilization, disciple Downs should certainly help lay the foundation.

"Yes—Disciple will definitely assist Master with all his might."

Lein nodded and, within the System, transferred another magic infusion permission to Downs. In fact, Downs knew more magic than his Master.

In the blink of an eye, Downs had copied all his magic into the "Physical Network" in his spiritual world.

Lein merely glanced at the System and was so shocked he bared his teeth.

Seeing spells like "Electric Claw," Lein wasn't surprised. The outrageous part was the additional remark in the System's evaluation. After comparing it with the data obtained from the magic books Ganis brought last time and reviewed by the System, Downs's version of "Electric Claw," when compared to the "Electric Claw" used by mages in the "Magic Network Era," was evaluated by the System as having a 138% increase in power, a 30% reduction in mana consumption, and a 59% increase in casting speed.

Downs's version of the magic completely crushed the old version.

Lein marveled at how outrageous this kid Downs was.

For a moment, Lein even considered copying the Magic Web Goddess's method, making spellcasters pay the corresponding mental and magical energy to gain the right to cast a certain spell. He, the master of the 'campus network,' could just be an awesome authority figure.

Then he thought again.

Not good!

Very not good!

The Goddess of Magic, playing with the magic net, ended up blowing it up and killing all the mages who used it.

Lein had no interest in replicating this earth-shattering mistake.

The lesson humanity learned from history was: humanity would never learn from history.

But the Magic Web Goddess wasn't human.

Lein would absolutely not step on this landmine.

Although the "Physical Network" at this moment was, to put it bluntly, powered by Downs's magic while Lein was freeloading, Lein had still thoughtfully prepared layers of challenges for potential new users.

As long as a user's strength reached the corresponding level, they could "freely" try a certain spell ten times. Once they decided to bind to that spell, they would enter the official version.

The official version of magic is like taking an online class. First, the user needs to pay enough mental and magic power to the campus network, learn the relevant Science knowledge, and pass the small tests given by the campus network before they can continue to use it.

Not only is there a limit on individual magic spells, but there's also a clear daily usage limit for all magic combined, preventing the unrestricted abuse of magic.

Want to use magic infinitely?

You can!

Purchase the [Advanced Edition] of magic. Based on the magic theories left by [Physical Network], you can summon elements or magic power from nature yourself, reaching the level of self-casting, and then you can cast the same magic infinitely.

Perhaps someone will ask, if one can already cast magic by themselves, what need is there for your [Physical Network]?

This is a trap set by a certain transmigrator, no, it's the key point.

Don't think that any random mage can achieve the same effect as Downs when casting the same spell!

It's like everyone shooting a gun; do you think everyone is a sharpshooter who can hit a bullseye every time?

The magic created by that monster Downs is almost the optimal solution in this era.

Even if the user doesn't covet Downs's magic, there's still Lein's bonus.

The System has a clear explanation for [Physical Network]: [Given that the host's mastery of (Junior High Physics) perfectly aligns with the fundamental laws of this world, the power of Evocation Magic used by this magic network's users will increase by an additional 23.33% when casting spells!]

Seeing this explanation, Lein was completely speechless.

So, in the eyes of this world, he, Lei, is an undeniable 'physics' Archmage!
