Sunny's coffin is tightly preserved and brought back to his hometown by spaceship and will be interred in Machi town next year.

Kiyo watched the ship about to take off from a corner of the window, no longer wearing mourning clothes.

People do not allow Kiyo go to the ship to mourn, so next to Sunny, there are no relatives.

Kiyo sighed, returned to the house, and pulled the curtains.

The brown-haired boy who always talked about computers in those days is gone forever. The boy's life was a series of twenty-nine years with many uncertainties, and then ending in despair.

Kiyo looked at the CVP who was hovering silently.

Looks like it already knows about it.

It looked out, bewildered.

It realizes it has become an orphaned robot.

It hadn't seen Sunny's face once since it left.

Every occasion the CVP would fly in front of the altar, and then stand there until the afternoon.

I didn't expect robots to feel pain... At least better than some people.

Soon after, the case about Sunny was broadcast on television.

Ha Nam, Ninh Binh and Nam Dinh were the ones who destroyed him.

Sunny was considered an enemy so no one here will mourn for him except Kiyo.

No one knows what happened at Ikusaba school eleven years ago, only that Cosmic Vietnam is about to invade their country and they have to defend their Homeland.

***

Tam Dao, June 2029..

The bright sunlight shines on the bushes and the steep climbs, making it feel heat, despite the clouds.

One person was holding a big red umbrella and was walking on that road tiredly.

That is Phu Tho.

"Oh my god, I didn't expect it to be this hot in Tam Dao.. Climate change?"

Following him were two others.

A man who was waving a fan, wearing a hat, sweating, turned to ask the person wearing a brim hat and carrying a picnic bag:

"You're able to stand under this sun, Vinh Phuc?"

"Yeah, I'm the opposite of Phu Tho, I really like this, Ha Nam! Come on, Yen Bai and Cao Bang are waiting!"

Phu Tho walked ahead, holding an umbrella, but still felt like it was about to melt in the hot sun.

Since when did he invite the other two? Besides, what kind of hat is he wearing?

Oh my god, I'm going to die...

At that moment, the two people Vinh Phuc invited were already waiting at the picnic area.

To avoid the sun, they planted a large umbrella around the red carpet.

Yen Bai saw that everyone came too late, waited for more than twenty minutes, couldn't call forever.

"When will these people come? I can't call!"

"Isn't your phone out of money?" - Cao Bang looked at him and said.

"Hey!" - There's a voice from somewhere.

"Huh?" - YB looks up.

"Did everyone wait long?" - VP laughed, put the picnic box on the ground.

Cao Bang patted Yen Bai's shoulder:

"Here he comes."

"I know. Wait, that guy is.." - YB pointed to Ha Nam.

"Huh?"

Phu Tho pats Vinh Phuc's shoulder:

"Ah, that's VP's boyfriend!"

"Shut up." - He sighed.

I'm just joking..

"Ha Nam is just my close friend, don't label us."

"We don't do anything." - Yen Bai took a bite of cinnamon.

Vinh Phuc sat down, opened the picnic box:

"Okay, forget it, let's eat."

Phu Tho looked at the dishes, although a bit simple but beautiful, admiring:

"Wow, are these VPs made by themselves?"

"Ah, me and Ha Nam do it together!"

Ha Nam awkwardly met a piece of rice with seaweed, unable to say anything.

Yen Bai looked around the carpet, saw that there was no bottle of filtered water, stood up and said:

"Hey, I'm going out to buy a bottle of filtered water, there's nothing here.."

"Yeah, be careful! There's been a few cases related to Cosmic Vietnam lately." - Vinh Phuc happily picked up a delicious fried egg.

He Nam took out a bottle of orange juice with two plastic cups:

"Um.. VP want to drink orange juice??"

"Oke, for my brother too."

Well, sitting on a carpet, touching the ground with green grass, trees all around, eating home-made dishes is nothing more ideal.

As long as this place is closely guarded.

A few minutes later, YB returned with a bottle of filtered water and continued eating with the other three.

The other three..

Cao Bang must be a little busy.. VP thinks so.

But twenty minutes later and still no CB, making all four start to worry.

"Hey, where's CB? Didn't I just see he was here?"

"He said there was some problem so he went out, but it's been twenty minutes and hasn't come back yet.." - VP wiped his mouth with paper.

It seems that the sun has calmed down, not as bright as when it first came up here. Phu Tho saw this, got out of the umbrella and said:

"Let's go find him! Anyway, the weather is calm, remember to pack!"

While cleaning, HN said:

"Hopefully CB won't be like VP in Sunny's game.."

"Huh?"

..........

Searched every corner, but the three still could not find any trace of CB. Called but didn't answer the phone, asked people around, everyone said they didn't know.

Ha Nam put the phone away:

"We have asked many people but no one has found.. Has he gone home?"

Vinh Phuc stopped at a corner of the wall, suddenly saw that the door of the warehouse was pushed open by the wind.

It was an unusual thing for him, for the place was always securely locked.

"Oh, the door isn't locked!'

VP gently opened the door, what caught their eyes are a corpse of someone.

The person was in a sitting position with his head down, blood dripping from the knife straight into his chest.

There were scratches on the wall and strange blood stains on the wall.

He Nam backed out, his face pale, trying not to scream.

"A..A.."

Yen Bai just ran back, saw all three standing there, surprised and asked:

"What's wrong- OH GOSH WHO IS THAT?????"

Phu Tho urges Vinh Phuc:

"C-call the police, hurry! Or else.."

"Oi!" - Suddenly a high-pitched voice rang out.

"Who is that?" - VP was dialing 113 when he was startled.

"You must not call them!"

Out of nowhere, a round robot with a colored background and a gray star, with a red antenna on top of its head, appeared right above the body.

It approached Ha Nam - who was looking at the ground, said:

"Hey, look up, listen to me. Let me introduce myself, I'm CV01-P, an artificial intelligence coming from Kyoshin."

Kyoshin.. Isn't that the hometown of Cosmic Vietnam?! Phu Tho thought.

"Call me CVP. I'll let you do this, but with one condition: Don't call the police! If you do, you'll look like this guy (but I don't kill). Now I will let investigate a certain amount of time, understand?!"

After that, the CVP left temporarily.

"What now?" - HN turned to ask.

"Now maybe we should investigate, then find the culprit.. The provinces have the right to investigate, right? I guess this case has something to do with Cosmic Vietnam's accomplices.." - YB said.

Confused, the four agreed to investigate the crime scene.

Ha Nam gathered up his courage and looked at the body:

"This person was stabbed with a white knife in the chest, I am not sure if it was hit in the heart.."

VP observes on the wall:

"The scratch on the wall.. it looks like the victim was trying to resist the killer. This person has been dead for fifteen minutes and he left something.."

PT uses paper, holds a strange bottle:

"What bottle is this? It's open but empty!"

"It's poison, don't smell it. Close the lid and put it down." - YB said.

"Hey, VP.." - HN called.

VP still hasn't taken his eyes off the wall:

"What?"

He held in his hand a vacuum bag, containing something.

"I found this.. Does it have anything to do with the case?"

"A broken knife? Where did you find it?"

"I found it in the trash, it's about to be taken away, so I have to wait-"

Another shrill voice came running in from outside:

"Ehem, ehem! I'm back! Are you done yet?"

Is it time? YB looked at CVP.

HN temporarily put a black towel on the body, make sure the scene is not affected.

CVP leads the three to a wall, presses a control, causing the wall to open up an elevator.

"You'll go down to the basement by this elevator, and one of you four is the killer! Just come in, I'll explain later. Upupupupupupu."

The elevator slowly descends, into a deep abyss that no one knows where it will stop.

The rattle and rock outside made them somewhat uneasy, as if afraid the elevator would crash at any moment.

He Nam leaned against the wall, looking down at the floor.

"Are you scared?" - Vinh Phuc calmly asked.

"...Perhaps so. Are you too VP?"

"If I say no, then it's a lie. But what can I do, who wouldn't shiver in this situation?"

VP sighed.

"But we still have to face the truth, no matter how hard it is to believe. That truth, it's in the evidence that we have collected."

Yen Bai stood close to the wall, holding something that looked like an Ipad.

Seven minutes later, the elevator stopped, opening into a room.

It was a room painted blue, with a black-and-white floor, with golden columns three meters apart.

In the middle of the room, there is a set of blue plastic tables and chairs, with four buttons under four layers of glass.

"Welcome to the trial room, I hope you will feel uncomfortable here. I bought this table and chair because what I needed was too expensive. Have you gathered enough information?"

It pushed the frame of the victim's photo next to the chair.

"In that case, sit down and I'll explain."

The four of them reluctantly sat down, two in a chair.

The CVP's ​​rule states: after finding the culprit, press the "Vote!" button! On the table, if you vote correctly, the killer will be executed, if not, vice versa. Whoever doesn't vote will go with the killer to the golden stream.

Why is this so familiar..? Phu Tho wondered.

"Feel free to debate. Oh, I forgot to say: The victim is Cao Bang!" - CVP said so, then kept quiet.

Ha Nam was stunned:

"It can't be.. the dead person is CB? And the killer is one of us?"

Yen Bai says:

"Hey, it looks like there were three of you out of the picnic area before that, right?"

"First Cao Bang, then Ha Nam, you last, right?" - Vinh Phuc replied.

"In that case, I think the most suspicious person here is Ha Nam."

"W-what?! You've alreasy thought he was the killer? Didn't you see his reaction when he saw the corpse?"

"Is that so? Okay, I'll prove it to you."

But Phu Tho found something problematic in Yen Bai's point of view.

Hasn't CB apparently died ten minutes before he was found?

There's definitely something wrong here... I'll figure it out.

And so the debate between Yen Bai and Vinh Phuc began.

The issue to be discussed is the timing of the crime.

"He went after me, but there's still enough time to commit the crime!" - YB said.

"Proof?"

"The two of you must have had animosity before, so HN used this picnic to quarrel with CB. When Cao Bang went out, Ha Nam followed and took the opportunity to kill him-"

Phu Tho suddenly realized the grain in Yen Bai's point of view, immediately said:

"No, that's wrong!"

"What?!"

"HN only went for four minutes, then came back with a bottle of water. It also took 10-15 minutes to do, the scratch on the wall clearly indicated that the two had a fight, isn't it?"

Yen Bai said nothing more.

"Put it aside, let's talk about weapons, okay?"

Ha Nam suddenly remembered something:

"Speaking of which, I found a broken knife in the trash, with some scratches on it too!"

"And this jar of arsenic, my brother just picked it up." - VP holds the vial of poison in a vacuum bag.

"You even brought it here too??"

Phu Tho pondered for a while and then said:

"Is that so. Both those and the knife on Cao Bang's chest are weapons... So how did the killer use them?"

"If so, then I have a theory:"

VP cleared his throat and said:

"The assailant had asked CB to go out before, then made a fuss and fought with a knife, but it seems CB was only fighting in self-defense. He was stabbed with his own knife and taken to the warehouse, where no one is paying attention.

Seeing that CB was not completely dead, the killer immediately forced CB to drink all the arsenic bottles, then wiped all the stains on his mouth. Before he left, he had one thing in mind:

So that no one would suspect a murder, he broke his own knife and put it in the trash."

Ha Nam listened carefully to that theory and also had his own opinion:

VP's theory is quite reasonable, the whole crime process is also very careful.. But while the killer threw the knife, what did Cao Bang do?

The blood stains on the wall must have meant something.. Could it be..

"Did you notice the strange mark on the wall?" - he asked.

"Yeah, what's with it?" - VP looked up.

"It's like this: Maybe while dying, Cao Bang remembered the killer's face and wrote his name, but wrote it in the opposite direction. If you turn it upside down, the word YB will appear. , then I only see one person here who matches it."

Ha Nam looked straight at a person:

"Is it you, Yen Bai?"

"Huh?" - He was startled.

"That's right! YB stands for Yen Bai, and in Vietnam it's the only province with a Y at the beginning!"

YB immediately objected:

"What's wrong with you?! Why did you immediately come to conclusion that I'm the killer?"

VP interrupts:

"We have gathered enough evidence that you are the most suspicious. If you ever blame Ha Nam again, I will not leave you alone!"

CVP began to panic.

Phu Tho summarizes the case:

"Earlier Cao Bang told us in advance that he would go out on business, but he added that it might take a long time because of the traffic jam. At that time, he thought of a way to destroy CB and find someone to blame. After he was out for seven minutes, he got up and pretended to go buy water, taking advantage of the time when CB was stuck in traffic.

It's true that He Nam was behind you, but he was only gone for four minutes, and brought the water bottle back earlier than you. Thus, you did leave the picnic, but he did not take into account that HN returned earlier than you, because when he returned, the two had already started fighting, and you chose Ha Nam to blame.

While we were waiting, you carried out the plan as VP hypothesized earlier, then returned as if nothing happened, right?"

Yen Bai's face was frozen, he didn't utter a single word.

CVP is increasingly afraid.

VP looked closely at YB.

"But I have one more question.. Why is YB shorter than my brother?"

"Yeah! Given the area of ​​Phu Tho and Yen Bai provinces, he should be taller, right?" - HN just realized now.

CVP flew up to him, scared:

"Master, it's too risky-"

"Shut up."

Then he sighed, suddenly changing his voice:

"Well, it's the end, isn't it?"

"Huh?" - Vinh Phuc did not understand.

"Because I'm not the Yen Bai you know.."

He raised his hand to his face, pulled the mask off, revealing the face of a man in his almost thirties, dark-haired, with a strand of hair protruding from the top of his head.

"Yes, it's me."

"Those yellow eyes with light skin.. could it be that you're-"

"Yes, I'm from Cosmic Vietnam." - He put his hat on. "I'm Kiyo and I never intended to kill any of you, don't worry."

"Didn't you just kill Cao Bang-"

"I came here to tell you some important information. First, I disguised myself as Yen Bai and another person dressed up as Cao Bang as perfectly as possible. He left to let me kill him. The two real people are still alive, because you didn't ask them to go, but invited us."

"Then why do you have my number?" - VP asked.

"Someone gave me YB's phone."

PT was shocked and exclaimed:

"Killing a person to for his own purposes.. God, that's cruel!"

"Actually, it's not like I intended to kill him in the first place. In that fight, if someone's knife hits first then the killer will do this job, assuming if I die he will do this for me, for example. Besides, this is the last time I follow his orders.."

"Last time? With whom?"

"Obviously, Cosmic Vietnam will attack this country next week!"

Ha Nam shuddered:

"Cosmic Vietnam.. really about to attack?"

Vinh Phuc immediately responded:

"Hey! Is he really going to attack next week? Or did you come up with another trick?!"

CVP immediately argued back:

"Hey you! Master is never wrong!"

"That's strange.. Did you guys kill Sunny but didn't know? Or am I in Cosmic Vietnam so I should have known sooner?" Kiyo clicked his tongue and took out a tablet.

"Well, let me explain. Anyway, he told me four days ago. As planned, there will be 800,000 CV troops going to the North and the Central region first, specifically the North Central region.

Cosmic Vietnam has marked a number of regions throughout the country as a springboard to attack key areas, and there is no information about the East Sea and the two archipelagos at this time.

If nothing happens, he will directly come down here to command. If he dies, there will be an Alter Ego (made by Sunny and his colleagues) to replace him.. Will continue to update in the near future."

No one said a word anymore. Besides Kiyo.

"It's still early to prepare, there's still chaos in our country, the army is handling the protests. There's nothing I can do about it either."

Kiyo hands over the tablet to Ha Nam:

"I give you this tablet to bring to the police station and use it to serve the resistance, there have been a few cases related to us recently. I heard that the Cosmic Vietnamese army is as strong as this country." - Kiyo walked to another elevator.

Ha Nam received it, still wondering:

"But.. You belong to his country too? Why are you helping us?"

"Actually, it's not that I have any sympathy for Vietnam, dummy." - Kiyo said the opposite of what he thought.

"Huh-"

"By order, I came here to see how smart you guys are, and it seems Vietnamese people are not really dull. But I want your country to win, not mine, because of the war of aggression he caused, it turned out to be unjust; moreover, the dictatorship over there was so rotten, there was no hope."

Kiyo gave Ha Nam the control switch that CVP had previously held.

"Here's the switch, you guys use it to return, I'll go another way. Let's go, CVP."

Kiyo then left using the same stairs, and the other three used the elevator just now.

Breathing the air and looking up at the sky, Phu Tho sighed:

"Finally getting out.. It's been like a year in there."

Vinh Phuc tries to regain his joy:

"Well, it's good to get out of there, isn't it? What else is there to worry about?"

"VP hasn't changed at all huh? Well, let's go back to the picnic area to get things and return, and prepare for the battle for next week!"

Ha Nam naturally held Vinh Phuc's hand:

"Um..hey VP!"

"What?"

"I.. I li-" - HN blushed slightly.

"Huh?"

"Ah, I mean.. Will you go to the millitary with me? Just wanted to ask."

"What's wrong? Of course I do! How could I let you go alone?"

Phu Tho interrupted:

"Come on you two, can we go home?"

"Yeah I know!"

So the three of them walked together on the gray tiles, preparing themselves for a big battle...

Meanwhile, at the National Assembly Building in Chushin, Cosmic Vietnam is still sitting in his office.

On the table were markers and a map of Vietnam, full of lines showing his army's offensive line.

CV mutters, that Kiyo gave the tablet to Ha Nam.

"Angie is dead, and Kiyo betrayed.." - He picked up the dart and threw it at the board. "It's all caused by them over there. I should never understimate them!

Then suddenly, CV grinned sinisterly:

"But then I'll show them what despair is!"

The dart was stuck in the picture of Hanoi, and on the board there were also pictures of five municipalities.
