13I stared at the phone. In that moment... My whole body felt cold. On the screen... Uncle Ma's chest was still slightly undulating. Black gloved hands... Slowly tighten the IV line. In the upper right corner of the screen, the time is clearly displayed. Not the old video. Live images. Khuong San quickly covered his mouth. Tears immediately welled up.

"Nam Tu..."

"What should we do?"

Manh Ky An's face turned pale. But he never touched the phone.

"Don't touch it."

He squatted down. Glance at the back of the phone.

"There's most likely a sensor underneath."

The two accompanying police officers immediately contacted the hospital. In the tunnel the signal is too weak. Calls stutter continuously. Can't hear the other end of the line clearly. The clock jumped to... From the phone speaker... The processed voice rang out again.

"Let Nguyen Nam Tu stay."

"Other people..."

"You can leave."

I looked at Uncle Ma on the screen. You can completely ignore me. You can throw the piece of paper away. You can pretend you don't know anything. But... Uncle still stood in the rain. It's my turn to choose. I can't back down. You can't risk your life either. I lowered my voice and asked Manh Ky An.

"Is there a way to send the signal out?"

He raised his head and looked up at the tunnel ceiling. Above is a row of old electric cable trays.

"This place was previously connected to the technical well of the new building."

"If the line hasn't been cut..."

"Maybe I can still borrow the intranet."

Khuong San suddenly raised his head.

"Let me try."

She quickly took out a data cable and a spare adapter from her bag.

"Previously, the finance department practiced emergency plans."

"I know the internal network connection format."

A policeman stands guard over the phone. The other person continuously used the walkie-talkie to call toward the ground. I pointed the flashlight forward. At the end of the tunnel... The red dot of light is still flashing. Khuong San's hands trembled non-stop. But she still gritted her teeth and climbed up below the cable tray. Manh Ky An supported her. And she quickly plugged the adapter into the old connection port on the wall. At that moment... The phone screen suddenly flashed. In the video... The gloved hand suddenly let go of the IV line. Tighten it again. The enemy knows... We haven't retreated yet. He's pushing us. I stared at the screen. Suddenly... I discovered a small label on the metal shelf next to the hospital bed. Is a series of codes. I immediately read it out loud. The police officer quickly read it back over the radio. A few seconds later... A broken voice finally came through the intercom.

"The ward has been determined."

"Third floor emergency room."

"Our people are going up there."

I breathed a sigh of relief. There's still hope for everything. But... The hand in the video is still there. At that moment... Khuong San suddenly shouted.

"Connected now!"

Her phone finally accessed a very weak internal network interface. The status of the authentication device is displayed on the screen. My dynamic code generation device... Online. Central control room. In addition... There is another strange device. Device name... Only one letter. I immediately looked at Manh Ky An. People of the Luong family. He is no longer in front of me we. Still in the system. At that moment... From deep inside the tunnel, a very soft sound suddenly rang out. Like someone kicked a metal plate. Two policemen simultaneously raised their flashlights. The light beam swept to the end of the tunnel. Behind the iron door... A shadow just passed by.

"Stop!"

A police officer immediately rushed over. I also ran along. Behind... Khuong San frantically called my name. But I... Never turned around. The iron door... Someone opened it from the inside. A small gap. Cold white light poured out. The central control room... Right behind that door. However... There is still an electronic lock on the door. The screen lights up.

"Please perform facial authentication."

I immediately rushed in front of the screen. The camera locked straight on my face. The cold electronic voice rang out.

"Identity anomaly detection."

"The system records two simultaneous login sessions."

"Do you want to forcibly revoke access rights?"

Without hesitation... I immediately chose: But right after that... The screen showed a second notification.

"Please enter the dynamic authentication code."

I clenched my hands. Authentication device... Was taken from my house. At that moment... Khuong San gasped and ran over.

"Use backup questions!"

"When I entered the company..."

"Your profile has been set up for an emergency verification!"

I stared at the screen. Security question appears.

"What was the first code project you ever worked on?"

My mind... Blank. At that moment... The voice on the ground rang out again.

"Ten seconds."

"At exactly ten o'clock..."

"Uncle Ma will stop breathing."

Manh Ky An immediately held my shoulders tightly.

"Don't let him lead you!"

"Remember..."

"Your first day at the company."

The first day... I sat at my desk next to the window. Mieu Tue hugged a stack of documents. Thieu Chan Hai passed by. He complimented my name very well. The project leader gave me the first folder. That folder name... Not the official project name. Internal password. I immediately entered those two words. The system is silent for a few seconds.

"Authentication successful."

I was just about to do the face scan... When the entire screen... Suddenly went dark. Inside the central control room... A burst of male laughter suddenly rang out. Right after that... Each light turned off one by one. The light disappeared. The whole space was in darkness. Right behind the door. Someone came close. Speak in a low voice.

"Nguyen Nam Tu..."

"Finally... you're here."
