This lord is very scientific.

"Building materials?"

Lin Ke's face turned dark when he heard this, and he glanced at Grandma Xisai.

"Hehe, hey, hehehe." Granny Xisai scratched her head.

"Indeed, it's too weak as a spectacle. Well, we haven't figured out the magic cement yet, right?" Lin Ke was speechless. Granny Xisai blew up the arena just to look cool. Who was he going to talk to?

Grandma Xisai is a poisonous person.

Her salary is clearly sufficient, but she still wants to defraud scientific research funds at any time.

She did not spend the fraudulent research funds herself. The places she spent money on, such as milk tea shops, were all opened by veterans, orphans and widowed mothers.

He is caring and kind-hearted, but he cheats on scientific research funds, which makes him speechless.

Lin Ke didn't know what to say about Grandma Xisai.

"Magic cement... I have no idea at the moment." Verun shook his head: "Those ordinary materials are difficult to incorporate with magic elements."

Lin Ke also understood that magic cement was quite difficult, so he did not embarrass Verun.

"Okay, which material do you think is better?" Lin Ke asked.

As an [Architect], Verun can replace all the building's materials without changing the building using only his skills.

"I made a plan, do you want to see it now?" Verun took out a notebook.

Lin Ke immediately moved his fingers.

Optical skill - Scattering!

Suddenly, words like projections appeared on the table in front of everyone.

"Let's read together." Lin Ke waved, and under the influence of pressure, the book floated over.

The followers could see that the words printed on the table were exactly the plans in Verun's notebook, and they immediately knew that this was Lin Ke's new skill learned in Father.

So, everyone started to look at the plan.

"I think this plan made of pure iron, silver and copper is very good! Haha, it's cool just thinking about it!" Lolita likes a pure metal plan, but the cost is more expensive.

"I think it would be good to use various elemental plants from the elemental forest to build it." Lika also spoke.

"This is not bad either."

"Huh? Using golden rhinoceros leather armor?"

"Well, how many flamingos will be killed with this plan..."

Everyone watched the plans one by one and then evaluated the plans.

Almost everyone has their own favorite plan, and of course, some of them are more optimistic and liked by everyone.

For example, the entire arena is made of metal, the shopping mall is best made of the gorgeous plants of the elemental forest, and the large library is made of ores. Every room in the wonderful land can have its own characteristics.

Finally, the plan was finalized.

After the plan was finalized, Viluen spoke again: "And..."

"Huh? Say it." Lin Ke looked at Verun.

As a friend of Garose, Viluen said that he and Lin Ke had different opinions, but Lin Ke would not completely regard Viluen as a follower.

"The thing that is most lacking now is actually the purple glow spar." Verun said in a helpless tone: "This kind of ore is also the main ore material for building the spire of our wilderness tower. A large amount of purple glow spar must be added to the construction of the four wonders. Crystals can form a magic circle."

"Can't you buy it?" Lin Ke frowned.

He also knows that after reaching a certain level, the purchasing power of money actually weakens.

The higher you go, the more common bartering becomes.

"You can buy it, but there are very few." Before Lin Ke could continue to ask, Viluen said: "Amethyst mineral veins, currently within the kingdom, only the Marquis of Dark Feather in the west has small mineral veins, but we have asked , he is not willing to trade.”

"Marquis Dark Feather?" Lin Ke raised his eyebrows upon hearing this: "One of the married families of the Brando family?"

The eldest daughter of the previous generation of the Brando family was his aunt, Antova Brando.

But I heard from the aunt that her father was a man who was keen on using marriages, alliances and other means to expand his power.

Like the Marquis of Jusword, they are also very familiar with the old Count Brando.

The youngest daughter of the Marquis Anyu family is married to Antova's brother.

"Did you tell me about my aunt?" Lin Ke asked.

"Yes, I said it, but the Marquis of Dark Feather is not willing to sell it. The conditions he needs are relatively harsh. He needs three star-level divinities, and he also requires darkness, wind and wood." Viluen's face also looked a little bit. Ugly.

"Well, are there any mineral veins elsewhere?" Lin Ke didn't think much about it after hearing this, and asked his aunt later.

"Yes, the Bandel Tiger Tribe of the Holy Life Alliance also has this mineral vein, but no one of us has been able to establish a relationship with them so far." Verun shook his head: "They simply treat us as slave lives. It’s impossible to trade at all.”

He continued: "There is nothing else. Amethyst mineral veins are relatively rare, or have little use, so not many people pay attention to them."

Amethyst is generally used as a raw material for certain lightning weapons.

However, amethyst is too brittle, so it is generally used as an auxiliary material rather than the main material.

Except for common mineral veins such as gold, silver, copper, and iron, most nobles and lords who discovered the mineral veins first thought of secretly mining and using them themselves. Only a few who could not use up the minerals would choose to sell them.

Like Amethyst, firstly, it is not powerful but rare, and secondly, it has too few uses and not many people pay attention to it.

So now, what is most lacking is the Amethyst Stone.

"Well, maybe we can go explore it then?" Lin Ke didn't understand it very well, so he asked Velun.

"Well, I've been looking for it, but the scattered purple fluorescent crystals I collected are not enough, and I can only barely build the spire of the Great Wilderness Tower." Velun was also in a difficult situation.

"Okay, I'll find a way to deal with this matter." Lin Ke nodded, and then looked at the next person.

[Mathematician] Ju Liuhe!

"Your Highness Lin Ke..." Ju Liuhe was still a little nervous.

Although she looked like a beautiful woman, her pair of pure eyes like a child and her nervous tone made people feel that the person sitting here was a little girl instead of a Star-level [Mathematician] whose power broke through the legend.

"Well, don't be nervous, how is the development of the mathematics project going?" Lin Ke asked gently.

Speaking of mathematics, Ju Liuhe was much more relaxed.

She breathed a sigh of relief, and then said: "In the field of mathematics, with the help of His Highness Lin Ke, we have developed many disciplines such as number theory, topology, etc. Everyone is very happy to be able to do research that they like, and we have also studied many things..."

Ju Liuhe reported in a rambling manner, or rather, it was not like a report, but more like a chat.

But everyone was listening very seriously.

Pure people can easily gain respect and love from others.

Especially people like Ju Liuhe who study mathematics purely for love.
