133. Seven all fifty one
late evening.
Incheol and I returned to the motel room located in Mokpo Port, and when we turned on the TV, news of the Iraq War came on the news.
TV screens showed US President Bush visiting the aircraft carrier Abraham Lincoln and announcing that he had accomplished his objectives in the Iraq War.
On March 18, the United States sent an ultimatum to Iraq, and two days later, on March 20, the United States began a war under the name of ‘Operation Iraqi Freedom’.
On April 9, 20 days after the war started, the Iraqi capital, Baghdad, fell, and 20 days later, on May 2, it was announced that the United States had accomplished its goal.
But the war in Iraq will not end as simply as President Bush announced.
Last Life I can’t remember any details other than the date the war in Iraq started, but… I know that for quite some time, fighting and terrorist incidents in Iraq have often been in the news.
Today is May 2, 2003. It’s a bit of a special day for me… Today is the day I came back to Korea after paying off my past life in America.
At the time, I thought my life was over, and that was the case. Because there was no place that accepted a failed genius, and I had no motivation to do something myself.

Not only this. He even suffered from an incurable disease called paroxysmal epilepsy in the military.
But in this life… I am healthy both physically and mentally, and I live and work with people I like.
Young-mi dreams of becoming a mathematician rather than worrying about making a living, and her mother is working as a professional translator rather than a daily kitchen assistant at a restaurant.
Okay, let’s not get too greedy.
For the past six months, I’ve been crazy about the number of 400 billion, and I’ve been running just looking at it… I thought it was enough just to enjoy the process so far.
It’s not that I don’t have money right now, and as a college student, I’m earning a lot of money.
I once again said in my mind.
okay! Let’s not get too greedy!
of course… … If you have 400 billion won, your acquaintance—it would be nice.
t-! While I was eating like that, I heard Incheol’s voice checking my laptop.
“Jeong-ho, I got a call from Uncle Jackson here.”
“Just ignore it.”
“I opened the file that Uncle Jackson sent me, and this is a 500-bit RSA ciphertext. If I use a geeky function, I think it will be solved in one room… ?”
I shook my head as I looked at In-cheol, and In-cheol licked his lips as if regretting it and continued.
“It’s five thousand dollars… ?”
The bonus is usually between $10,000 and $20,000, but this time it’s a bit high.
I shook my head again and said.
“In-cheol, don’t really do that. We are not working hand in hand with intelligence agencies.”
For reference, Ledger Jackson has requested decryption more than 10 times so far, and I am ignoring all of them.
“hey-! For fifty thousand dollars, this is 60 million won!”
At Incheol’s words, I smiled and said.
“Choi In-cheol! This is funny! Why do you keep feeling sorry for something like 50,000 dollars? A million dollars is a lot of money? yes?”
* * *
When I got a million dollars from Ledger Jackson six months ago, I didn’t think it was 100% my money.
Although I did the handling of the hacking incident, it was In-cheol who actually did the work (?). So I thought that In-cheol also had a stake in this money to some extent.
So, when I told Director Jackson about the money I received, Incheol opened his mouth with a sad expression.
“men and horses… ! You should have called at least five million dollars! The entire US administration was using the EXP cipher!”
I also felt regretful at Incheol’s words, but instead of looking sad, I opened my axe’s eyes and said.
“Hey—! I was taken away by the US military because of you, and I almost died, man!”
“haha-! Sorry!”
Incheol continued to speak while fiddling with his chin with his hand.
“Hmm… ! But why did you get caught? You didn’t do anything, did you?”
“I do not know either. There must be something wrong with the documents.”
“Perhaps if I had been arrested, I would have been on my knees and begged for my mistake. I lived thanks to you, Jungho. You saved me twice! Thank you very much! I will truly be loyal to you for the rest of my life. Little girl!”
At Incheol’s words, I smiled and said.
“But how are we going to divide this million dollars?”
“What? Why are you sharing it? Jung-ho, it’s your money.”
“I’m trying to gulp on my own, because my conscience is a bit pricked… .”
“done! I am not interested in other people’s money.”
“There’s no need to fuss later.”
“Of course. And that’s Jeong-ho, your money is right.”
“Okay, then I’ll take care of this money. But I have to tell Yunseok hyung too… .”
“president? Why is the boss?”
I am the person who discovered the weakness of the EXP encryption, but the development of the EXP password was something I did with Yoon Seok-yi hyung.
However, in order to explain this money to Yun-seok-hyung, I had to bring up the story of In-cheol’s hacking, so I asked In-cheol’s opinion.
“I wish I hadn’t told the boss… . The boss knows that I really am a good student.”
At Incheol’s words, I laughed and said.
“Well… ! Isn’t that right?”
“But don’t tell the boss. I don’t want to ruin the good image my boss has of me.”
I nodded, thought for a moment, and then opened my mouth.
“then… I think it’s right to spend this money for Yoon Sung Soft. And I’ll tell Yoon-seok-hyung to make your share in the company as well.”
“A share in company ownership?”
I nodded my head, and In-cheol said with a smirk.
“If it’s a million dollars… 11 billion or so? That penny, I don’t need it.”
* * *
“ah… ! right. I said pennies… .”
Incheol scratched the back of the head and continued.
“By the way, I thought I was going to pull out the 39 tons of gold right away. Haha—!”
Unbeknownst to Incheol’s words, a smirk came out. Because I was thinking the same thing.
“I know… I’m going to hit 400 billion in no time! I thought it was coming out… It’s not easy. under–!”
At my long sigh, In-cheol nodded and said.
“You know, there was a thing that looked cloudy all over the water earlier. I don’t think this is usually a problem.”
Incheol continued with a short sigh.
“Until now, Jung-ho, thanks to you, I’ve come this far, but this time… I don’t think it’s possible to solve it with human ability. Whoa—!”
While talking to Incheol like that, the news screen was moved to the Mokpo local broadcasting station. The central news ends and the local news continues.
The anchor opened the news tap and opened his mouth.
– Every spring, it’s a story that comes up all the time. It’s a drinking water problem in the island area. This time, there was even a claim that a water-borne infectious disease circulated. Reporter Kim Cheong-soo is connected to the scene.
– Yes, this is reporter Kim Cheong-soo. I am now in ㅁㅁ-do, Sinan-gun, and as you can see, the residents here dig a common well and use the groundwater as drinking water.
A reporter’s voice continued as the camera’s screen showed an underground water pump and an underground water storage tank.
-But recently, there was a report that there was a problem with the water quality of this groundwater, so I came to the site myself.
Interviews with island villagers began, and there was a story that an elderly man complained of abdominal pain after drinking groundwater a while ago and was taken to the hospital emergency room by a 119 helicopter.
And the news led to an interview with a professor of water treatment major in the Department of Civil Engineering at Klitschko University.
-As a result of analyzing the sample, it was confirmed that both E. coli and turbidity exceeded the standard values.
When the professor finished speaking, the reporter asked.
– So what should I do in this case?
-Actually, E. coli is not a big concern, as chlorination is done in the underground water storage tank.
– Yes, that’s right. So how do we solve the turbidity problem?
The professor answered the reporter’s question.
-To remove the turbidity of water, a process called coagulation treatment is performed in a general water treatment plant… … .
It felt like a flash in my mind for a moment.
I jumped out of bed and shouted.
“okay! This is it!”
At my words, Incheol looked at me with a surprised expression and said.
“What… Are you talking about?”
“There are things that look cloudy in the sea. I think there is a way to fix that.”
In-cheol’s expression brightened at my words.
“Also! Chae Jung-ho! I was firmly convinced that you would solve this problem!”
I checked the watch.
9:25 p.m.
I changed my clothes and said to Incheol.
“Can you tell me where the nearest university is from here?”
Incheol said while searching the internet.
“There is Mokpo Maritime University within a 15-minute drive. But what are you going to do at university this time?”
“I’m going to look for some books in the library over there.”
So I took a taxi to Mokpo Maritime University, and 15 minutes later I found the library’s major bookstore.
“The reading room will close soon.”
At the librarian’s words, I checked my watch.
“It will be over in just ten minutes.”
I went through the reading room into the library and started looking for books.
＜Water Chemistry>
＜Physical and chemical water treatment process>
＜Water Engineering>
＜Water Quality Engineering>
＜Drinking Water Treatment>
I took out these five books and quickly turned the pages, poured all the contents of the book into my head, and left the library at 10 o’clock.
dawn the next day.
I drove to Gunsan City with Incheol, and we arrived at the Gunsan Industrial Complex at 9 am and found a company called ＜Mankyung Chemical>.
“250 kilograms of solid aluminum sulfate? But we are only supplying to water treatment plants… We do not sell this to individuals. There must also be a record of the order form.”
At the company employee’s words, Incheol put saliva on his lips and opened his mouth.
“I… president. We are graduate students of Korea University Water Treatment Lab. We are testing a large reactor right now, and the alum (aluminum sulfate) has run out.”
Incheol continued speaking with a pitiful expression on his face.
“I should have placed an order in advance, but I forgot last week. If we get caught by our advisor, we will all die.”
At Incheol’s words, the staff looked at me with a questionable expression, and I quickly took out my student ID and showed it to the staff.
“Sir, I’m going to ask you this one more time. Our professor has a very fiery personality.”
Incheol continued with tears in his eyes.
“Your boss—! Please save us.”
If In-cheol had become an actor or an actor, he might have been really successful. Anyway, thanks to In-cheol’s tearful acting, the staff nodded and said.
“Wait. First of all, we check stock.”
The employee who was rummaging through the documents nodded and said.
“Yes, it is possible. If you want to transport it by car, it would be difficult to take it in liquid form… So, shall we shred the alum so that we can use it right away?”
At the employee’s question, Incheol looked at me, and I asked the employee.
“How big is it before shredding?”
“It will be about a millimeter in diameter.”
aluminum sulfate or alum.
The exact chemical formula is Al2(SO4)3-18H2O, and the specific gravity is about 1630 g/L.
According to the physicochemical water treatment engineering I studied last night… Three forces act on an object that settles in water: gravity, buoyancy, and dragging.
And by using the equilibrium of these three forces, the sedimentation velocity equation of the object can be derived, which is called the Stokes sedimentation velocity equation.
As a result of calculating the specific gravity value (1630 g/L) and particle size (1 mm) of a given aluminum sulfate by substituting it into the Stokes sedimentation rate equation, the sedimentation rate is 13.7 meters per minute.
In other words, if aluminum sulfate grains are sprinkled from the sea, they reach a depth of 79 meters, which means that it takes about 6 minutes.
However, since aluminum sulfate grains become smaller as they dissolve in water, the actual sedimentation rate is slower than this.
In other words, it would take more than 10 minutes to reach the bottom of the sea 79 meters below.
I told the staff.
“Do not crush it, just give it as is.”
So we purchased 250 kg of aluminum sulfate and returned to Mokpo Port with the purchased aluminum sulfate in eight bags.
The sea of the West Sea seen from Mokpo Port is calm without a single wind.
OK!
