In Sumeru, pretend to be a scholar!

Because of Liam's enthusiasm, Wang Yan had to stay in the Grand Bazaar for half a day longer, and was only able to leave after having dinner there.

After bidding farewell to the enthusiastic Liam, Wang Yan left the Grand Bazaar.

"Formula, raw materials, production line... all of these are settled. Now, there's one last question."

Wang Yan walked home while pondering with his head down.

Although Sumeru is a land of knowledge, its production has clearly not yet reached the point of being unmanned.

Therefore, to produce toothpaste, you first need a factory with enough space to operate the production line, and secondly, you need enough workers.

Production lines are not something that can be started and then left unattended; production ultimately depends on people.

"It seems... we still have to rely on the Order of the Church." Wang Yan pondered for a moment, then looked at the massive structure on the Sacred Tree.

As scholars of the Order of the Church, isn't it reasonable for them to take some of the venues and personnel from the Order of the Church?

My advisor said that I need to learn how to apply for funding from the faculty.

Venue and personnel are also forms of funding!

"However, we'll have to ask Farusan for the specifics."

Now that I've taken Farusan as my mentor, I'll definitely have to make use of that relationship.

Wang Yan was not clear about many of the rules of the Order of the Instruction, so it would be good to ask Farusan for advice.

The journey was smooth, and we returned to our rented room in the accommodation area from the Grand Bazaar.

The house now contains many more items than when Wang Yan first rented it, mainly books and various miscellaneous mechanical parts.

Wang Yan bought most of the books himself, while the parts were provided by Farusan, all so that Wang Yan could quickly become familiar with the basics of mechanical arts.

"Hmm, it's been a long time since I cleaned."

Wang Yan turned on the light, glanced at the scene inside the room, and frowned. He had indeed neglected cleaning lately because he had been busy with his studies and projects.

His gaze swept over the pile of notes on the table, the scattered parts on the floor, and the thin layer of dust accumulated on the windowsill, and suddenly an idea struck him.

"I've been learning how to control wind element runes these past couple of days...maybe I should give it a try?"

He recalled Farusian's teachings: "Flow" is the foundation of wind, "gathering" can constrain airflow, and "swirling" can guide direction.

Of course, in Farusan's account, she does not have the Eye of God and cannot directly manipulate elemental forces.

However, Wang Yan had successfully manipulated the grass element using the language of the abyss before, so Wang Yan is not without means to drive elemental power.

"Why not use the Abyss Language to drive elemental power, and then use runes to precisely control it... just consider it a practice session."

Once the idea of ​​using wind elements to clean was conceived, it began to grow rapidly.

Extraordinary power... is indeed one of the things Wang Yan desires most after transmigrating.

Recalling Farusan's teachings, Wang Yan calmed himself and moved his fingertips swiftly through the air.

First, outline the rune lines representing "flow," with faint blue light traces emerging; then, layer "gathering" to make the airflow converge inward; finally, add a light "swirling" to give the wind a gentle swirling force.

At the same time, he lowered his voice and recited the short phrase in the Abyss language in that filthy yet ancient tone: "N』gha zhaor… fhtagn ya."

This is a variation of the spell I learned from the Sealed Demon Scroll, replacing the grass element command with the wind element, roughly meaning "Gathering winds, heed my call".

The moment Wang Yan finished speaking, a subtle ripple moved through the air inside the room.

A wisp of breeze was born from his fingertips, initially as thin as a spider's thread, then slowly spreading under the guidance of the runes.

It swept across the bookshelves, stirring up dust; it brushed across the tabletop, carrying away scraps of paper; as it hovered over the ground, even the smallest fragments in the corners were gently drawn into the airflow.

The wind was gentle yet precise, like an invisible hand carefully gathering up the clutter.

Dust and debris gathered into a small gray cloud in the airflow. Wang Yan gently guided the cloud with his finger, and it floated steadily toward the trash can in the corner, slowly falling into the can.

The whole process took only a dozen or so breaths, and the room was completely refreshed with fresh air, except for a thin layer of dust in the trash can.

Wang Yan withdrew his hand, looked at the scene before him, and couldn't help but smile, a very happy smile on his lips.

"As expected, using runes to control form and using the language of the abyss to drive elemental power, this combination allows me to master extraordinary power."

"But... I still don't know what the cost of using Abyss Language is... I can only use it as a trump card..."

"The best solution... is to find an extraordinary language that can replace the language of the Abyss."

Wang Yan pondered inwardly,

Although it seems that he has no side effects from using Abyssal language to drive elemental power.

Wang Yan sometimes even wondered if it was because he, like the Traveler, possessed the status to bear the abyss.

But Wang Yan ultimately maintained a sliver of rationality.

As we all know, the abyss is an extremely dangerous force, and its greatest characteristic is its powerful allure.

Perhaps, what appears to be without side effects is simply the abyss tempting Wang Yan to delve deeper?

Therefore, Wang Yan could not say that he would never use the language of the abyss, but he must use it slowly, rhythmically, systematically, and reasonably.

"The only extraordinary language I know that can replace the Abyss language is the Dragon Clan's [Engraved Inscription]."

Aside from the [Engraved Light Mark], Wang Yan was unsure whether something called the Light Realm Language existed, or whether the language once wielded by the angels possessed extraordinary power.

"Once the toothpaste project makes money, maybe we can issue a quest to have adventurers bring over some photos of [Engraved Inscription] from Nata."

Nata is quite dangerous. There are many monsters left over from the abyss in the wild, as well as untamed dragons. Wang Yan doesn't want to risk his life if it's not necessary.

The Adventurers' Guild is such a great place, it definitely needs to be put to good use.

As long as you have money, you won't have trouble getting a proper [Engraved Inscription]. If all else fails, just assign the quest to the traveler through Catherine.

Anyway, Wang Yan only needs photos to interpret the text.

For travelers, taking some "engraved" photos is nothing special.

While thinking about things, Wang Yan went to the washroom to quickly wash up, then returned to his desk and took out a book titled "Analysis of Basic Mechanical Structures".

His life is very regular now.

I get up at eight in the morning and go to bed at ten at night, and I read for two to three hours every day.

To be honest, Wang Yan himself never imagined that he could live such a healthy and regular life.

If he had had this patience before his transmigration, and had spent two hours reading effectively every day, he would have taken off long ago.

However, it's not too late now. Let's work hard and strive to create a bright future in Teyvat.
