"Prosecutor Kim, what's the problem?"

Seeing that Gu Ji had been staring at the central rearview mirror, Cui Ridou subconsciously asked.

Gu Ji squinted, "That car has been following me for a long time, sit tight." ”

As soon as the words fell, he stepped on the accelerator and quickly distanced himself from the black Hyundai sedan, and shook off the "tail" completely after a few traffic light posts.

An hour and a half later.

He finally arrived at Park Bo-mi's house without any problems.

Because of the MERS incident, colleges and universities across the country have implemented the closure of classes, so students are basically studying at home.

Park Bo-mi's family lives in an alley in the south of Pyeongtaek City.

Gu Ji knocked on the door.

Suddenly there was a dog barking in the yard.

“ham！ Stop screaming. ”

Gu Ji heard someone coming from the courtyard, opened the gate, and it was a middle-aged woman wearing a gray robe with her hair coiled, "You are ......"

"Ms. Zhang Meixi? Seoul Central District Checkpoint. ”

"Get out! You are not welcome here! ”

Unexpectedly, as soon as Gu Ji showed his documents, Zhang Meixi stretched out his hand and pushed them out, and as she spoke, her eyes were also wet and red, "My husband is dead, what are you doing here!" ”

He also knew that Park Junyeol's death was a big blow to the family, so he said in a low voice.

"I am very sorry about Mr. Park Junyeol, I am here this time because I have something important to ask you, which is related to the cause of your husband's death."

"What?"

Gu Ji's words instantly stopped Zhang Meixi's choking.

Eventually, she decided to let the two in.

"I'm sorry, there's been a bit of chaos in the house lately, you guys just sit, Baomei, go pour a few glasses of hot water!"

"You're welcome, ma'am."

Cui Ridou scratched his head, looking a little embarrassed.

Park Junyeol's family is not bad, after all, he can be selected as a researcher at the secret research institute of the US-South Korea joint military base, and the salary is definitely not low.

A moment later, a young girl in a white shirt and skirt walked over with a wooden tray.

After seeing Cui Ridou, he let out an "ah", so frightened that the hot water kettle on the plate almost overturned.

"What's wrong, Bomei?"

"Mom, he'......"

"You are Park Bo-mi, don't be afraid, Choi Il-dou was specially arrested by me to apologize to you." Gu Ji showed his ID again and identified himself.

Zhang Meixi reacted at this time.

It turned out that Cui Ridou's embarrassed expression just now was completely because he didn't know how to face his daughter.

After a roll of the eyes.

The four of them sat around the coffee table in the living room.

Gu Ji didn't ink, and went straight to the point, briefly repeating the suspicions about the cause of Park Junyeol's death that he had just found, but he didn't say that it was the military's move.

"So please think about it carefully, has Park Junyeol explained to you recently?"

"No, my husband rarely asks me to take care of him, and he doesn't let me go to the hospital to see him since MERS started to catch on."

Zhang Meixi shook her head.

"Dad, he ......" At this moment, Park Bo-mi suddenly remembered something, and repeatedly swirled her index fingers in front of her abdomen, and glanced at Choi Il-dou with some hesitation.

"Don't be afraid, I'm the prosecutor." Gu Ji saw her concerns and immediately reassured.

"When I went to see him in the hospital, he told me to take care of the piggy bank."

"Piggy bank?"

"Yes, that piggy bank was a birthday present that my dad bought me when I was in elementary school, but I haven't used it for many years, so I wonder if he wants to tell me something?"

After saying that, Park Bo-mi went back to the bedroom and brought a small rabbit ceramic piggy bank.

Gu Ji took it and studied it carefully, but he couldn't see any way.

"I can ...... it"

"Yes."

With Park Bo-mei's consent, Gu Ji smashed it, and there was a lot of change scattered inside, but he found a black memory card in the silver glittering coin.

Gu Jiyan was quick and immediately picked it up.

"Have you ever seen this?"

"Nope."

Park Bo-mi shook her head.

He stared at the memory card and shook his eyelids.

It seems that this is what the military is looking for, and it is estimated that Park Junyeol secretly recorded the information a long time ago, brought it out, and hid it in his daughter's piggy bank.

Maybe it was because he discovered some bad behavior in the laboratory, or maybe it was to add a hole card to himself to prevent the military from unloading and killing the donkey one day in the future.

In short, the military should have found traces.

sent someone to search a large circle, but found nothing, so the object of suspicion was transferred to the person in charge of the eucalyptus, that is, "Kim Ji-gyu".

"What else did your dad say besides this piggy bank?"

"Hmm......"

Park Bo-mi tilted her head and remembered for a moment, and suddenly a flash of inspiration, "I remembered, he said that when the accident happened, it seemed that he saw a person with a black hood." ”

"Black hood?"

Gu Ji knew it in his heart.

Sure enough, as he analyzed, the explosion in the laboratory was caused by an attack by outsiders.

Just wearing a black hood is not a criminal feature at all, after all, no one is stupid enough to show their face and attack the military district.

Just as he was about to get up and leave Park Bo-mi's house.

Somehow.

A figure suddenly and instinctively flashed through my mind.

The terrorist boss at the airport checkpoint in Germany!

If the "black hood" that Park Junyeol refers to is really a feature, then what impressed Gu Ji the most was Cohen, who led the terrorists to attack the airport when he broke through the border for the first time!

At that time, before Sam Yin's death.

The first time he saw Cohen, he thought it was a little strange, it was clear that all of his men had their faces exposed, but he was the only one, wearing a black hood.

In the end, before the end of the level, this guy was not caught by the government forces.

It can't really be the same person, right?

The reason why Gu Ji can think of this person is mainly because he met Jiang Songyuan in this classic level, otherwise he may not be able to remember this Cohen with just a "black hood".

Shaking his head, he felt that it was important to solve the problem of the military region's laboratory for the time being.

He left a phone call for Park Bo-mi's mother and daughter to contact at any time if they had something, and he would do his best to investigate the cause of Park Junyeol's death, and then leave with Choi Il-doo.

On the way back to the car, Cui Ridou scratched his head, his face full of puzzlement.

"Prosecutor Kim, was Park Junyeol really assassinated? It can't be a mulberry, right? ”

"Shut your mouth, don't ask what you shouldn't."

Gu Ji walked to the car at the mouth of the alley, subconsciously glanced at the surrounding environment, did not see the black modern car, leaned over and glanced at the chassis of the car, and after confirming that the bomb was not placed, he shook his hand and said: "You come to drive, go back to the ground inspection." ”

"Oh, okay." Cui Ridou obediently came to the co-pilot, opened the car door for Gu Ji, and immediately got into the cab.

Ignition, start.

After turning his head, Cui Ridou stepped on the accelerator, and the front of the car rushed out in an instant.

"Slow down." Gu Jigang took out the phone.

Prepare for Jang Se-yoon to contact the police station to protect Park Junyeol's family.

"I'm sorry, Prosecutor Kim, I'm used to driving fast, hehehe!" Cui Ridou said haha, and after stepping on the brakes twice, his complexion suddenly changed, "What, how ......?"

"What's wrong?"

"Prosecutor Kim, it seems that the brakes are suddenly not working!"

"What?" Gu Ji's eyelids jumped, and he suddenly felt that the vehicle was accelerating again.

He quickly turned his head, and sure enough, in the side rearview mirror, he found the black Hyundai sedan suddenly rushing out of another alley, so he decisively pulled the door handle, but found that it could not be opened.

"The car was tampered with, and control of the vehicle's OBD system was taken over."

"What ABC, Prosecutor Kim, what should we do now, the speed is already over 130 km/h!"

Cui Ridou couldn't understand what Gu Ji was saying at all, so he could only watch the car get faster and faster, clutching the steering wheel, and a layer of sweat oozed from his forehead.

"Honk the horn to remind, repeatedly step on the brakes, pull over on the expressway, and use the body to rub against the metal guardrail to slow down!"

Gu Ji looked at the Hyundai sedan behind him, quickly judged the current solution, and then immediately called the police station and informed the accident location.

He just finished speaking.

Cui Ridou suddenly hit the steering wheel sharply, made a sharp turn, avoided the vehicle in front, and scared others to keep honking their horns.

"Buzz!"

"Dididi!"

"Fuck, I'm scared to death!" Cui Ridou cursed with expletives in his mouth, but his hand followed Gu Ji's instructions and approached the roadside guardrail.

Seeing that the distance was getting closer and closer, he could only close his eyes, and his heart was horizontal, and he pasted it.

I only heard the sound of "bang", the body vibrated violently, and then I could hear an extremely harsh friction sound coming from the door panel on Gu Ji's side, as if there were a hundred cats' claws scratching the steel plate.

But the effect is surprisingly good.

The speed of the car really slowed down.

Gu Ji took the opportunity to stuff the [Poison Needle Trap] mine and ERC signal jammer in the briefcase into the waistband of his pants, and he could guarantee that he would take it out immediately at a critical moment.

It's a pity that he didn't carry a high-frequency electromagnetic shielding device this time.

Otherwise, with a light touch, you can isolate the signal control of the person behind you.

Ever since cars became electronic, there has been a danger that outsiders are taking control of the car, and as early as 2011, researchers from the University of Washington and the University of California demonstrated how to wirelessly unlock a car door and brake it urgently.

Hackers can control functions such as slowing down, shutting down the engine, and braking abruptly or disabling the brakes.

But theoretically.

In the automotive industry, mechanical priority must be higher than electronics, especially brakes.

That's why Gu Ji said that someone had moved the vehicle, which changed the underlying logic of the car.

The first thing he aimed at was the central control area.

After dismantling the driving computer, Gu Ji took out his mobile phone and looked at the wiring harness structure inside with a flash, thanks to the fact that he had a lot of accident emergency handling knowledge stored in his mind, including emergency maintenance of various car accident vehicles.

After rummaging for a long time, he finally found a controller that was connecting the ends of the cable and glowing red.

Gu Ji tugged hard.

Suddenly, the body began to slow down violently.

"Hey! That's it! The brakes are good! Cui Ridou was repeatedly stepping on the brakes, and suddenly felt the familiar rebound force, and the body began to slow down violently.

But at this moment, "Peng" sounded.

I don't know if it was because the side friction was too long, and the front tire suddenly exploded.

The front of the car began to shake uncontrollably from side to side, and finally "banged" and hit the guardrail.

"Uh-huh......"

Cui Ridou gritted his teeth, turned his head, and squinted at Gu Ji beside him, "Prosecutor Jin, ......are you okay?"

"Be careful!"

Who knows, Gu Jimeng pressed his head a few times.

In the next second, "boom", the windshield shattered in response.

"Get off! Get out of the car! Gu Ji took off his seat belt and kicked the car door.

"West Eight Miles! Is this man crazy? Dare to shoot on the highway! "Even though Cui Ridou usually does a lot of black-hearted business of robbing homes and houses, he is not bold enough to do this after all.

He also learned Gu Ji's movements and rolled out of the car door.

But since Gu Ji is leaning on the guardrail of the expressway, and outside the guardrail is the grassy slope and woods, it is easy to avoid the shooting vision of the gunman of the black modern sedan.

And Cui Ridou could only roll down the avenue.

He cursed and hid behind the front of the car, looking for an opportunity, and also climbed over the guardrail.

The door of the black sedan opened, and a figure wearing a black cap and a dark gray sports sweatshirt, armed with a pistol with a silencer, chased after him from behind.

"Suddenly!"

After being suppressed by the silencer, the pistol is still very loud, but it is a lot strange, it doesn't sound like a gunshot, plus this is a fast road, the speed of the car is very fast, for a while, no one even paid attention to it.

didn't wait for the two of them to run a few steps.

A bullet suddenly hit Choi Il-doo's waist.

He let out an "ah" and fell to the ground.

Gu Ji looked back and saw that the black hat killer had already caught up.

"Let's go!

Cui Ridou got up from the grass with his arm support with a painful face, pulled out a yellow knife from his waist with his right hand, and scolded loudly at the killer: "West Eight Miles, Lao Tzu is the Mountain Dog Gang, Cui Ridou!"

”

"Suddenly!"

Two more shots, right in Cui Ridou's chest.

The killer didn't even look at him more, and continued to chase after Gu Ji.

Accurate marksmanship and crisp strikes.

Yes, it has special training.

Military!

Gu Ji threw himself into the grove in one breath, hid behind a tree trunk, looked back at Cui Ridou who was dead on the ground, and the killer who was getting closer and closer, and constantly adjusted his breathing.

To be honest, he never thought that Cui Ridou would give up his life at a critical moment and let him run first.

Or, Choi Il-doo is returning the kindness of AM Hospital;

Or, as he himself knows, once he gets shot in this situation, he can't run away.

But no matter what, without the two shots that Cui Ridou contained, Gu Ji might not have been able to hide in the woods in time.

He pulled out the [Poison Needle Trap] mine from behind his waist, gently threw it on the edge of the tree trunk, took a deep breath, and continued to run away into the distance.

"Suddenly!"

The gunman fired two bullets at the edge of Gu Ji's disappearing tree trunk, and then quickly caught up.

But just when he was within range of the [Poison Needle Trap].

The killer's pace suddenly began to slow down.

It seems that he is also worried about what Gu Ji threw just now.

But after looking for a long time, he didn't find any clues.

In the next second when the killer took a bold step, "Peng", the weeds on the ground burst open in an instant, and a large number of poisonous needles hit the woods, and his cheeks were also pierced into hedgehogs!
