In Sumeru, pretend to be a scholar!

Zakaria truly deserves to be called the best physician of Mount Sumeru, and even more so, he deserves to be called the "Habantha" of the Life Theory School.

After watching Wang Yan mix bamboo salt and herbal powder with baking soda to make a paste, he fully understood and grasped the essence of toothpaste.

Then, he quickly improved Wang Yan's technique.

Furthermore, some medicinal herbs that Wang Yan was unfamiliar with were added.

"The herbs I added can effectively help whiten teeth, while also giving the toothpaste some anti-sensitivity and enamel repair capabilities."

Zakaria explained to Wang Yan.

Wang Yan sighed inwardly, marveling at the truly high level of the scholars at the Academy of Teachings.

Even though he hadn't made any further requests, and it was just one round of optimization, Zakaria had already brought out many of the selling points that toothpaste manufacturers had advertised in his previous life.

As expected, the Order of the Church is not lacking in technology. They have been able to make toothpaste for a long time. It's just that ordinary people have always used charcoal and salt, while scholars can often use alchemical mouthwash from Mondstadt or tooth powder from Liyue.

In addition, the scholars' business acumen was generally poor, which allowed Wang Yan to snag a bargain.

If Dolly had collaborated with someone from the Life Theory faction instead of the Theory of Subtlety faction, then Wang Yan wouldn't have had the opportunity to propose such a thing.

"This is absolutely fantastic, Senior Zakaria! The glory of the Life Theory School has been brought to life before my eyes!" Wang Yan exclaimed loudly, changing his address from "doctor" to "senior."

Zakaria's lips curled up slightly.

Zakaria had heard enough of the usual compliments and thanks.

But Wang Yan's words about the glory of the Sheng Lun school truly touched his heart.

"Ahem, so we'll stick with this recipe? No need for any further improvements?" Zakaria coughed lightly, suppressing the upturn of his lips as he asked.

Wang Yan nodded: "The effect is about right now. Next, we need to find a few people to verify the toothpaste's effectiveness. Also..."

Just then, there was a knock on the door.

Upon opening the door and seeing Kavi, Wang Yan smiled and said, "We were just about to talk about you. Senior Zakaria has already improved the formula."

"Well, so you need me to design a production line, right?" Kavi said, then looked at Zakaria, "Could you tell me what materials and production steps are needed?"

"Of course, in addition to the basic formula provided by Wang Yan, we also need to add the medicinal herbs I just prepared. And for better commercialization, we also need to add abrasives, compounding agents, sweeteners, active ingredients, etc..."

"As for the problems that need to be solved in the production process, the key is mixing. The raw materials in different forms, such as powder, liquid and colloid, need to be thoroughly broken down and blended to form an extremely fine and uniform paste."

"While mixing, be careful not to mix in too much gas, so as to form a more stable paste."

Finally, it's time for packaging.

Zakaria briefly explained his thoughts.

Wang Yan stood to the side and suddenly felt like he was a bit useless.

Aside from proposing this project, Zakaria solved all the other problems, and now the production issues also need to be addressed by Kavi.

"It's alright, it's alright. I'm the leader; the leader is the most important."

Wang Yan reassured himself, then looked at Kavi: "Do you think these needs can be met?"

Kavi didn't answer immediately. After thinking for a moment, he nodded: "Leaving aside the preparation and weighing of raw materials, what I need to solve is mixing and homogenization, followed by vacuum degassing and packaging, right?"

He gave a summary.

Wang Yan and Zakaria nodded: "That's right."

"There's no technical problem, it can be solved, but..." Kavi hesitated.

Wang Yan immediately asked, "But what? Is there some difficulty?"

Kavi blushed slightly: "However, we need some funds to purchase materials for the organization..."

Wang Yan immediately breathed a sigh of relief: "I thought it was some big problem. How much do you need?"

Kavi calculated: "Let's start with a simple one to test if the technology is usable. It'll probably cost around 100,000 Mora."

Wang Yan didn't ask how the money should be spent, but simply said, "I'll give it to you in a bit."

"Then I have no problem." Kavi smiled.

Wang Yan thought for a moment, then asked, "Where do you plan to source the parts and materials from?"

"Hmm? Do you need to keep track of the expenses? I'll give you the bill." Kavi thought Wang Yan wanted to see how the money was spent.

He didn't feel distrusted at all; having done many projects, Kavi had a lot of experience in finance.

Even in the best relationships, money matters must be kept clear.

"No, you misunderstood. I gave you the money so you could spend it. I wanted to ask if I could use your channels if I needed to purchase some materials for mechanical arts," Wang Yan explained.

After studying with Farusan for several days, Wang Yan had a general understanding of the basics of mechanical arts.

But what you learn from books is never enough; you must put it into practice to truly understand. Once you've learned the basics, you have to put them into use. Otherwise, how will you know how well you've learned them?

Initially, Wang Yan intended to seek help from Farusan, since she was his mentor. However, upon seeing Kavi, a scholar of the Mysterious Theory school, he realized that Kavi's connections might be stronger than those of Farusan, a scholar of the Epistemological school.

"I see. The Mysticism School has its own material channels. If it's a very rare material, we usually entrust external merchants to help us purchase it." Kavi paused, glanced at Zakaria, and then continued, "You've probably heard of the famous merchant Dolly, right? We purchase many things from her."

"Although the price is not cheap, the quality is guaranteed and the supply is stable."

Zakaria raised an eyebrow: "I'd heard the Mysticism School had some wild connections outside, but I didn't expect it to be this person... But, junior Kavi, I remember you owed Dolly money before? You're actually collaborating with her?"

Kavi's lips twitched, his expression somewhat unpleasant, but he still explained, "I owed Dolly money because of my own reasons. Now that the money has been paid back, the cooperation will naturally continue. After all, Dolly's commissions can sometimes be quite profitable."

Dolly loves money, but she's not stingy; otherwise, she wouldn't have been able to build a trade network spanning multiple countries.

"Big Merchant Dolly, could you also help me purchase some materials? Maybe we can negotiate a better price if we put them all together," Wang Yan said.

Kavi nodded: "Of course, no problem. What do you need to buy?"

"I'm planning to make a small self-defense mechanism. I'll probably need some extraordinary materials that can hold elemental runes. I'll give you a list later."

Wang Yan's current means of self-defense are actually limited to using Abyss Language to drive elemental power.

But the existence of Abyss Language is indeed very filthy and doesn't seem safe.

Next month, Wang Yan will be going on a field expedition with Farusan again, so he plans to make a small self-defense device, something like a small repeating crossbow. With elemental runes, its destructive power will be considerable.

Of course, this is also because crossbows have a relatively simple structure, making them suitable for Wang Yan to try out, and crossbow bolts can be bought directly on the market, which is relatively convenient.

"Okay, I'll buy it all together later and give it to you," Kavi agreed.
