138. Seven all eighty seven
The next day, August 15, early morning.
I woke up to the sound of the phone.
It was a text message from Professor Ki-seong.
– Student Jungho. I think the explosion test will be difficult due to the circumstances of the laboratory.
Soon after, his second text came in.
– The Ministry of Education guidelines on explosives came in this morning. I even promised to test it from next week, but I’m sorry.
I let out a long sigh. And I sent a short text message to Professor Yeom, thanking him for letting me know.
By the way… this… Something is strange.
Today is Liberation Day and Friday. In other words, the 3rd is the start of the Golden Week holiday, but the guidelines came down from the Ministry of Education this morning?
I suddenly remembered the story I had with Team Leader Kim Jung-soo last night.
All of a sudden, a question about whether you are dissatisfied with society, a question about whether there are people you hate, a story that one of your subordinates has a fixer, and even a final warning not to get into an accident… .
ah… !
It is clear that the NIS took notice.
But how would you know?
Explosives recipes were deliberately used only by American search engines. So, unless the search engine company informs you, there is no way to know the contents of my IP search.
Suddenly, I realized that my internet search was excessive. The search engine company would have reported it to the US police, and the US police would have asked the Korean police for confirmation through Interpol. Perhaps, before the police started the investigation, Team Leader Kim Jung-soo informed me in advance.
Since it was planned to secure the initiator first, chemicals for TNT manufacturing have not been purchased yet. In other words, if you are being investigated by the police, you can say that you searched out of curiosity.
But no matter what happened… It is clear that the plan has been disrupted.
“under–!”
I texted Incheol with a long sigh. It seems that preparing explosives will be difficult for the time being.
About ten seconds after I sent that text message… .
The visit swung open.
“why not? What’s going on?”
I said, getting up from the bed.
“When did you come?”
“It doesn’t matter now! What’s going on?”
I told Team Leader Kim Jeong-soo and the message I just received from Professor Yeom, and In-cheol asked me with a sad expression.
“You said that TNT can be made even if the purity is a little low? How can you not do that?”
I continued by explaining the difficulty of underwater explosions and the need for a high-purity initiator.
“Now we have to find another way. I think nitro-based initiators will be difficult in the future.”
“Nitro series? what is that?”
A nitro functional group is a strong oxidizing agent and is included in almost all explosive agents, and these are called nitro-based explosives.
As far as the police and the NIS know, possession of a chemical containing a nitro group is… Making bombs is no different than surrendering yourself. So, you need to prepare a nitro group-free initiator.
At my explanation, Incheol said with twinkling eyes.
“Five! Jungho, are you thinking of something?”
I said with a smirk.
“There is a way… This will take some time.”
“Does it take time? How?”
“It’s a method using electrochemistry.”
“Oh oh-! Electrochemistry! there seems to be something But why is it taking so long? Do you need a lot of time to study this?”
I shook my head. Actually, my studies are over… .
“It has to be safe, but it takes time to make enough catalysts.”
In-cheol asked carefully at my words.
“Then what I did… Can I continue?”
Destroying the hatch door to the second basement floor of the Shigemitsu and the door to the gold bar is not the end of the job.
Once you enter the Vault, you must now pick up the Gold Bar.
Even taking into account the buoyancy, the weight of a one kilogram gold ingot in water remains almost the same at 0.95 kilograms. That means underwater drones need a robotic arm. There are several problems, but one of them is the sophisticated control of the robotic arm.
In particular, since the underwater drone weighed only 1.7 kilograms, an algorithm was needed to balance the drone along with the operation of the robotic arm.
So In-cheol is currently developing this algorithm and at the same time collecting information on the international gold trading black market.
“Yeah, go ahead.”
A smile spread across In-cheol’s face at my answer, and I got out of bed, stretched out, and continued.
“But when did you come?”
“You came late last night. After work, I had a drink with the boss, but I was too lazy to go to Namseo-dong’s house.”
“Then you slept on the sofa without a blanket?”
“yes.”
“I have an extra blanket in the room here, so I came in and took it.”
“a-! It’s hot, but the blanket, what?”
I said checking my watch.
“Let’s have some rice. I got ribs stew from Yeongmi’s mother yesterday.”
“really? Kimchi and side dishes were all in the refrigerator?”
“It’s frozen, so it’s in the freezer.”
“Oh yeah-!”
In-cheol ran straight to the kitchen, and I said to In-cheol.
“He said it was ready, so I just thawed it in the microwave and warmed it up a bit.”
“OK-!”
After breakfast, Incheol took a seat in front of the computer in the living room.
“men and horses! Aren’t you going home?”
“I even cleaned the dishes. Take a look.”
Incheol continued speaking while fixing his gaze on the computer monitor.
“ah-! I want to buy an officetel and be independent!”
I said with a smirk.
“It looks like room 809 was released next door here.”
At my words, Incheol said with a serious expression.
“Five-! Really? How much is the rent for an officetel here?”
I can’t remember the regional fluctuations in real estate prices in the past, but I do know about the fact that shepherds are becoming a very hot place. This was one of the reasons I bought an officetel in Mok-dong, not in front of Hankuk University.
“Well… I don’t know about the charter, and the sale price is probably less than 100 million won.”
Incheol nodded, and I continued.
“Your school is close here, and Yunseong Soft is right in front of you. Don’t you have some money you’ve saved up so far?”
In-cheol receives quite a bit of performance pay from Yunseong Soft. After being discharged from the military, Incheol-i investigated in detail the security problems of the customer servers managed by Yunseong Soft, and thanks to this, a large-scale renewal of the contract and renewal of the contract were made.
In fact, it was as if In-cheol had come with a contract. In the process, Yoon Seok-yi changed the company’s performance-based pay system, but it was almost as if it was changed for In-cheol.

Nevertheless, no one in the company has expressed any dissatisfaction. everyone knows The fact that the bonus they received was all thanks to In-cheol.
When I asked if the money I had saved was not enough, Incheol smiled bitterly and said.
“My father is in debt. I just paid it back.”
“Didn’t you say that you don’t have to pay it back?”
“I still have to pay it. I only sent the principal for this one… .”
I don’t know the details… It is said that long before In-cheol’s father passed away, he asked a close friend to organize his business. At that time, in the process of organizing the business, the friend suffered a lot of financial loss, and it was only after a long time that In-cheol realized this.
“OMG-! I wish that 100 million just fell from the sky.”
At Incheol’s words, I laughed and said.
“wait a moment. I’ll be fishing for gold bars soon—!”
There really isn’t much left. Now there are only two tasks left.
Crafting explosives that break hatch doors and storage doors, and crafting an arm that picks up gold bars for an underwater drone. .
39 tons of gold will come in your hand.
Without realizing it, the corners of my lips went up, and In-cheol seemed to be thinking the same thing, and he smiled and said.
“If I take out those gold bars, I will buy an officetel here first.”
“men and horses-! For 400 billion won, you should buy a building in Gangnam, not here.”
At my words, Incheol shook his head and said.
“No, I like this place more than Gangnam. It’s close to Yoon Seong Soft, my house is close, Ji-eun’s house is close, my school is close, and Jeong-ho, you are close too.”
“Yeah, I also want you to get an officetel soon. That way, you come to my house less often.”
“ha ha ha-! Don’t be so harsh. But every time I come, I pay for the meal.”
At Incheol’s words, I smiled and the phone rang at the same time.
“hello.”
-Hi, J-Ho. This is Director Jackson from the Defense Information Systems Agency.
It was Director Jackson.
Unknowingly at the sound of his voice, the mask of reporter So-Jeong was put over his face.
For reference, ‘J-Ho’ is… Perhaps the pronunciation of the name Jeong-ho was difficult, and it was the name that Director Jackson used every time he sent me an e-mail. Of course, I never replied to any emails he sent.
Anyway, up until now, I had no idea what he would call me ‘J-Ho’, but the moment reporter So-jeong’s mask was put on… My displeasure soared at the fact that he changed my name at will.
I opened my mouth with a short sigh.
“(Don’t call me that way. It’s offensive.)”
-(Ah…! That, I’m sorry. Mr. Chae.)
“(I don’t know what’s going on, but I don’t have anything to say to you. And now I don’t want you to send me any more ciphertexts, because I can’t and I don’t want to. I’ll stop then.)”
– (Wait! Mr. Chae Jung-ho!)
what? Were you able to pronounce my name well?
Somehow… This is going to make me feel worse.
I waited without saying anything, and after a while Director Jackson continued.
-(I made this phone call to make a request. This case is very different from the passwords I have sent so far.)
“(Are you referring to the cipher text sent two days ago?)”
The detoxification bonus was a whopping $150,000. So far, performance pay has been at most $120,000, and the highest is $60,000.

Not only this.
The ciphertext he sent two days ago was clearly different from the previous ones. It was not an RSA ciphertext, and it was highly probable that it was a codebook cipher, judging from some repeated numbers and spacing patterns.
With the reply that the cipher text sent two days ago is correct, the voice of Director Jackson was heard.
– (Since last week, the movement of JMJ members has been detected outside Baghdad, Iraq.)
JMJ is one of the extremist Muslim terrorist groups, which I’ve seen previously in the data given by Director Jackson.
Director Jackson continued.
-(It was confirmed a week ago that a member of the JMJ gang had purchased a large amount of bombs through a Russian arms broker called Svetlova. This means that they are preparing a large-scale terrorist attack…)
I cut off Director Jackson’s words.
“(Sorry, I’m Korean. I’m not interested in terrorist organizations in the Middle East.)”
Director Jackson’s low voice came along with a brief sigh over the phone at my words.
-(Then, what if the bonus was raised to $200,000 instead of $150,000?)
Even if you pay 20 million dollars instead of 200,000 dollars, this is not something you can do.
In order to crack the codebook password, a large amount of encryption data is required first. Last time I was able to crack the V-19 code tag… It was thanks to over 600 pages of cryptographic material.
But this time, it was all an email containing 139 numbers. It is impossible to crack the codebook cipher table with this.
I said into the phone.
“I am sorry, General Jackson.”
And now I hung up the phone with the words not to contact me in the future.
“Hey Jungho… … .”
Whoops—!
In-cheol was right next to me.
“what? Maybe you… Did you hear everything?”
In response to my question, Incheol nodded. Then he put his face in front of me and looked at my face to and fro.
“By the way… you… Is this the Chae Jung-ho I know? yes?”
In-cheol rubbed his arm and continued.
“Wow—! Look at the creeps on your arm. Chae Jung-ho! You don’t speak English in front of me anymore. It’s like a completely different person. I’m really scared. OMG… !”
Incheol, who looked at me with wary eyes, continued.
“By the way, if it’s ‘Two Hundred Thousand’… That’s 20 thousand dollars. Hmm… .”
Incheol went to the computer and checked the cipher text sent by Director Jackson, and said with a smirk at me.
“Jungho, shall I try to solve this?”
