“Just tell me how much money you want!”

The World

As soon as Luck returned to his room, he changed his clothes and sat down at the computer.

The desire from Elsa and Senna to repair the walls of the compound was always in the back of his mind.

Quickly surfing the internet, Luck went to an old website selling building materials and started looking for information about cement.

"Oh my God...there are so many types of cement."

"Do you really need so many types of cement?"

Aluminate Cement: It is used for structures that require high temperature resistance and has fast hardening properties.

White Cement: Used in decorative projects for aesthetic purposes; white version of standard Portland cement.

Fast Hardening Cement: Fast hardening; especially preferred for emergency repairs and cold weather conditions.

Composite Cement: Portland cement with various additives; environmentally friendly and less costly.

Sulfur Cement: Sulfur-based cement with high chemical resistance, preferred for marine structures.

Portland Cement: The most widely used type of cement; used in general construction applications.

Pozzolanic Cement: Contains pozzolanic materials such as volcanic ashes; suitable for water resistant and low temperature applications.

Water Resistant Cement: Known for its water resistance in areas such as water structures, dams and harbors.

High Strength Portland Cement: Especially used in the construction of bridges and high-rise structures; high strength.

Blast Furnace Cement: Slag-added, used in harsh environmental conditions such as acidic soils and marine structures.

In today's world, construction used to be built by pouring High Strength Portland Cement around steel and carbon alloy skeletons.

This type of cement, which used to be used only in the construction of large-scale projects such as bridges and dams, is now used in every field.

Luck examined the cement information one by one and said, "High strength Portland cement...I think it can be used for the walls of the compound...let's see how much it costs."

...

...

Luck: (◎◎ヘ)

What the fuck is that?

Five thousand dollars a ton!

Five thousand dollars a ton of cement! 

How much would it cost to build the walls of the compound with cement?

A 10-kilometer wall 5 meters high and 3 meters wide...

Luck briefly gasped as he made a mental calculation.

Valume =5m×3m×10,000m=150,000m3

Cement quantity = Volume x Cement density

Cement quantity = 150.000 m3 x 300kg/m3

Cement quantity = 45.000

45,000 TONS!

45,000 tons×5,000 USD/ton=225,000,000,000 USD

Luck felt like fainting.

I thought I was rich when I made some money...

Elsa...Senna...

I'm sorry I gave you false hope...

I couldn't buy this much cement even if I sold myself!

What if I use one of the cheaper types of cement?

Oh no... even those cements start at 150 million dollars....

With the idea of building the walls of the compound with cement gone, Luck shut down his computer and went to bed with a sigh.

Even if I had enough money, why would I buy all that cement? I don't have a construction company!

Let's say I bought all that cement...I would have to travel between two worlds 2,000 times to carry all that cement with my 5m2 space ring!

This immature idea of mine was doomed to failure from the start...

...

The Next Day in Gliese.

After Luck had passed through the door of his room in his own house, as usual, his eyes landed on 'his room' in Nikolai's house in Gliese.

"Ah...now how am I going to explain this to them."

The door to the room suddenly opened.

"Luck! You're here at last!"

Luck was startled by the suddenly opened door. 

Elsa and Senna were at the door, looking excitedly at Luck.

"Let's go! Dad is waiting for us!"

"Yes! We've been waiting for you all morning, where have you been!"

"Father is very curious about how you are going to repair the walls! We must start work as soon as possible."

Not giving Luck a chance to speak, the two girls took Luck by each arm and started dragging him to

Nikolay's room.

Luck: (-_- )

At least let me speak...

...

"Dad, we're here!"

"We caught Luck as soon as we found him and brought him here, Dad! 

Nikolai looked at his two daughters who had entered his room without even knocking.

His two daughters were holding Luck tightly by each arm, refusing to let go.

Nikolay: ...

Luck: ...

Dude, I tried to make them let me go...but I couldn't do it!

Nikolai looked meaningfully at his two daughters and Luck "Ahem...girls..."

When the two girls followed their father's eyes, they quickly let go of Luck's arm, realizing what they were doing.

Not knowing what to do out of embarrassment, Elsa excitedly pushed Luck in front of her father.

"Luck, come on, explain."

Luck: （＾_＾）

Explain what! 

That I'm broke?

Luck sighed deeply, realizing that he was going to destroy the hopes he had unintentionally given them.

"I'm sorry...but I can't help you this time..."

Luck's words shattered the smiles of the two girls who were smiling with excitement as if they had been hit with a hammer.

"Luck, what do you mean you can't help us? Just yesterday you said you could help us."

"Yes, Luck, you even told us today that you would explain how you would help us!"

"I only said maybe... but unfortunately I can't do anything, I'm sorry..."

Senna tearfully said "NO! You seemed so sure! You just weren't sure about the durability!"

"I'm sorry...even if there is something that can repair the walls, it's beyond what I can afford..." 

As the two girls were disappointed after hearing Luck's words, Nikolai's attention was caught by something Luck said.

"Beyond what you can afford?"

"So you really know something that will help us repair the walls of the compound, but you can't get it?"

Luck nodded in agreement.

"If it's a question of money, you don't have to think about it! I'll sell my own personal equipment if necessary and pay for it anyway!"

Luck was secretly saddened to see Nikolay's determination.

Nikolai's concern for the safety of his compound and his people was evident.

"Yes, money is the problem, but even you can't afford it, Nikolay..."

Nikolai slammed his hand on his desk in anger.

Luck's words seemed as if they would cause him to return to the darkness when he had seen the light.

"You don't know that! Don't belittle my decades of savings! I'll even give you a year's income from the compound if I have to!"

"Just tell me how much money you want!"
