The excavator's arm occupied the road and pushed the accident vehicle, which had been upside down, to the side.

Craaashhh!

-A little more to the side! Yes, it's done!

The firefighter who was leading earlier sent a signal saying that it was over.

The excavator was parked next to the road and Dowook got out of the drivers seat after turning it off.

Lee Ji-seok came straight to his side.

"Wow, doctor. Are you Jet America? Actually going in and to treat the patient, manipulate the equipment, and even help with rescue work. We just came to support, but we became the main lead."

Dowook asked Lee Ji-seok, who mentioned the main character of a famous hero movie.

"Main lead?"

The fire team leader, who was guiding the site, briefly saluted Dowook. The firefighters standing around also sent him a nod with respect.

"Can you see this? My shoulders are tense for no reason, right?

While moving to the transport bus, everyone they encountered greeted them with a smile.

"Thank you for your hard work, doctor. When installing airbags, too. Thanks to you, we safely rescued them."

"Are you sure you're a volunteer? If it weren't for you, I would have been in big trouble in this traffic chaos."

A strange camaraderie that could only be felt by those who had saved people while struggling together. It felt different from the experience of emergency rooms that were like war zones and was conveyed in their greetings.

When he returned to the transport bus, someone opened the window and popped out their head.

"Park Dowook!"

It was Seong Chang Soo.

"What the hell are you doing going around like that? Tell me if you're going to disappear. Do you know how hard it was for me to deal with reporters?"

Noh Myeong-deok next to him made eye contact with Dowook, and said it wasnt true and gestured that the reporter was scolded by that mouth.

"Anyway, hurry and come up. While working all day, I prepared several secrets to achieve the special order. At night, following the operation of youth.

Dowook sighed at the thought that he had to endure Seong Chang Soos chatter while returning. He tried to get on the bus, but the ambulance stopped next to him.

Han Min-gyu, sitting in the driver's seat, lowered the window and told Dowook.

"Doctor, get in here. It's narrow there."

"May I?"

Seong Chang Soo, who was talking, closed his mouth. Dowook looked at him.

"The special mission was almost resolved when Director Lim came earlier. Don't do anything to undermine the hospital image at night."

Dowook got into the ambulance passenger seat.

"Director? When? When did a beautiful girl come? What's up with that special treatment?"

Seong Chang Soo's voice echoed in the air towards the departing ambulance.

LT Communication, Ahyeon District Underground Communication Ward, 9:30 p.m.

The cable driver, who was looking at the 500m-long underpass with a lantern, headed to the entrance after confirming that there was no problem.

When he climbed the long stairs and opened the door, the superior who was looking at the server room turned his head.

"How are you?

"Are you sure the danger signal was detected? I think we just need to change some light bulbs inside. I think it was malfunctioning because of too much noise.

"Is it because of Mr. Yoon's electric shock? Check the small things thoroughly.

Booom!

A dull noise was heard from the ventilator side, and the heads of the two engineers turned.

"What's going on?

Booooooom!

This time, the noise sounded for a bit longer.

"This is from the bottom."

The two drivers, whose eyes met, opened the door to the underground road and ran down.

Crack!

The two people who opened the door and looked back had to swallow their moans.

Flames were pouring from all sides.

Fwoooosh!

"Report! Report!"

Outside the LT communication building.

Sizzling smoke began to rise from the manhole on the road.

The smoke gradually gathered and stretched to a 17-story complex right next to it.

As the smoke reached a huge poster with "Show Me the Rhyme! The Bounce that Makes Your Heart Beat!" written on it stuck at the entrance.

Splurt!

The manhole lid popped up and crashed through the window of the shopping district where the lights were off.

However, the roar of destruction was soon buried in the exciting rhythm and cheers coming out of the building.

Sinchon-daero, 10:25pm.

Dowook was in an ambulance with a patient lying helplessly due to peripheral dizziness.

Looking out the small window at the bumpy feeling of the car, he could see a familiar street and a familiar access road.

The patient, who was the first dispatch during the late-night hours, was currently on his way to the emergency room of Myeong Sae Hospital.

"That's right. You were a doctor at this hospital, right?"

Dowook replied with a smile to Lee Ji-seok next to him, who asked questions and yawned loudly.

"I ran really hard to promote that Im from this hospital today."

"I know you worked hard. I'm a member of the team, but I'll say it unconditionally if anyone asks me at the district office. Trust me."

"Thank you."

Lee Ji-seok, who was glancing outside on the way to the hospital like Dowook, suddenly said as if he just remembered.

"I don't know if the patient from last week is okay. He was injured while working on cables deep underground, and he was in the worst condition among the patients I've ever transferred.

"Cable work? Did he get an electric shock?

"Yes, it was a patient who had a heart attack from an electric shock."

While scheduling the operating room, he remembered seeing it from the surgical information of another doctor. The case outline remained in his head because there were few electric shock patients.

Dowook briefly stated his opinion as a doctor.

"He was scheduled for a second surgery for a skin transplant at the plastic surgery clinic. The problem related to life has already been solved."

"Oh, really?"

Lee Ji-seok, who looked relieved, yawned again. Dowook said this, recalling the request Han Min-gyu made during the day.

"You don't have to come in the second half of the night. I can just sit here and keep in charge. Let's have Professor Min sit in the passenger seat."

"How can you do that?"

Lee Ji-seok, who wiped the tears caused by yawning with his sleeves, smiled.

"The team leader is working overtime just like me because of this event. I can't be the only one who can rest."

Dowook turned toward the driver's seat.

A superior who cared for his juniors to rest but did not show it at all. His personality was different from someone who responded with a roar whenever he had time.

As well as his outstanding experience as a paramedic, the fact that he was an emergency rescue worker in charge of the area was relieving thought.

An ambulance stopped in front of the emergency room.

"Were here".

At the signal from the front, Dowook opened the back door and began preparing to help the patient get off. Then, he met eyes with the emergency room medical staff who came out to meet him. And he rubbed his eyes to see if he saw wrong.

"Chief?

Chief Ha Sang Joong also saw Dowook and was surprised.

"Why are you sitting there? It's off today.

Chief Ha's eyes headed toward the clothes of a volunteer worker worn by Dowook.

"What? Did you go to the disaster prevention event that made everyone go crazy about getting leave today?

"It's"

Dowook lightly pushed the stretcher to settle on the floor quickly while pushing the bed into the emergency room as he reported.

"The patient is 51 years old, and I did a Dix Hallpike test because he showed symptoms of neuropathy, and I think there is a stone stuck in the semicircular canal. You have to transfer it to neurosurgery right away and start with CT."

"Don't change the subject, punk! Why did you drop by after delivering the patient from our department on an off day?"

"You know. If you clear this event, you'll get a call exemption."

"Huh."

Dowook asked Chief Ha, who was following from the side.

"What about you? I just called neurosurgery. What brings you here? He's not even a VIP."

"Do you think that I came because I wanted to?

Chief Ha, who looked so angry, took his cell phone out of his pocket.

"The call phone is dead. But some crazy intern made an emergency call with an extension to the chiefs office. There was no one in the medical department."

"You were on duty."

"I'm on duty because of someone!"

"A transaction is a transaction. A man should keep his word."

"So? You run this kind of event on a golden off day from the deal? You're still a surgeon like that!"

"What do you mean by this kind of event? Consideration of citizens for citizens. I'm a volunteer."

"Shut up!"

Dowook calmly received Chief Ha's temper, which continued until he arrived at the general treatment room. In front of the call exemption right, all anger was just a lullaby.

"Professor Choi will also be interested in semicircular nerve surgery, so please take good care of this patient. I'm going back."

"Hey, Park Dowook! I'll see you later!

He moved to the reception desk, leaving Chief Ha's cries behind. After putting a bag containing the patient's belongings on the reception desk, he spoke to the nurse.

"That patient who just came in. The guardian is going to be a little late. If the phone rings, please pick it up for me. She's the daughter, but she's very worried."

"Okay Huh? Dr. Dowook? Oh my. You came in dressed like that, so its a bit strange.

"Do I look good in a uniform?"

"When Dr. Chang Soo came, it was really awkward. He got pretty confused as he was making notes about the patient like a doctor."

Perhaps Seong Chang Soo was very funny, the nurses around him covered their mouths and giggled.

Dowook, who received a sign confirming that the patient had been transferred, stopped looking at Chief Ha, who was swearing at the call phone.

"Nurse. Are all the phones not working right now?"

"It suddenly doesn't work. The internet is also getting really slow."

"Really? Why?"

Bzzzt.

During the conversation, a voice was heard from the walkie-talkie on his shoulder.

-Dr. Dowook. Please board as soon as possible if the patient transfer procedure is completed. We have dispatch orders to the LT Communications Building due to a fire.

"On my way."

After the transmission, Dowook pushed the empty stretcher and disappeared out of the emergency room like the wind.

"119 General Situation Room, LT Communication Fire Report Transcript".

Yes, 119.

There's a fire! It came out really big! Here Oh man. Here

Sir. Take a big breath.

(Breathing heavily)

Yes, here. This is the Ahyeon branch building of LT Telecom. Underground.

I got it. Seodaemun Fire Station will be dispatched.

It will be difficult with just a few fire trucks. You have to send as many as possible.

Can you tell me the exact scale of the fire?

Depth of 6 stories below ground. It is a 500m long underground road. Here, 170,000 covered wired circuits are connected to about 200 trillion optical cables that are vulnerable to fire. If this continues, the Internet and telecommunications, and a third of Seoul will die.

(Sound of static noise. Call again later)

LT Communication Ahyeon District, 10:33 p.m.

Seodaemun Fire Station's first-aid team's vehicle stopped on the roadside.

Dowook lowered the window of the passenger seat and turned to a six-story building that had no room to enter due to the fire trucks that had already arrived.

Because all holes leading to the outside were occupied by black smoke, the smoky smell filled the air, as the distance was quite far away.

Han Min-gyu in the driver's seat reached out to operate the walkie-talkie himself and contacted the headquarters.

"First aid team 1 of Seodaemun Fire Station, we arrived at the driveway."

-Okay. Please wait for medical treatment at the site.

Dowook asked Han Min-gyu, who put down his walkie-talkie.

"There's a big fire like that. Do we just wait?"

"There were no people in the building. The rescue team conducted a life search and came here first to prepare for the discovery of a secondary patient.

"Oh."

Police cars gathered at the entrance to the scene.

Shortly after the traffic police began to control the entry of regular cars and induce firefighters to enter.

The cell phone in Han Min-gyu's arms rang.

"Yes, son."

-Do you know there's a fire next to where I am?

"Huh?"

Han Min-gyu's eyes turned to the opposite side of the building under fire control.

A complex building with a 17th-floor tower and a 5th-floor multipurpose shopping mall connected in an "n" shape. At the entrance, there was a poster of the performance that his son was going to see.

"Dad is also on the way to the fire scene, so hurry up and go back home with your friend after the performance."

It was not a distance to catch fire, but as a parent, there was a nagging that worried him.

-That thing is, Dad. I called you because I thought this building was shaking a little.

"The building is shaking?"
