Hidden in the shadows, Ding Zhu took one last look at the people who were reveling in the hall, and turned to run towards the stairs on the second floor.

Along the way, it was not unsurprising that they met a few hooded men, but they all lost their combat effectiveness in an instant under Ding Candle's resolute attack, and the black hoods seized from them were already enough to complete the task of two people, in addition, they also picked up a lot of light machine guns, but unfortunately because of the task restrictions, they can only be used in the mission, and cannot be taken out of the task.

Ding Zhu made a plan and threw them all to the points store to redeem points before the end of the task.

If it weren't for this trip, I would have returned empty-handed.

Seeing that they were about to reach the stairs on the first floor and the second floor, a sharp alarm echoed through the building, piercing everyone's eardrums.

"Alarm alert! There's scrap to escape! Alarm alert! There's scrap to escape! This is very dangerous scrap! Attention, this is very dangerous scrap! ”

The overhead sirens echoed through every corner of the building, ensuring that everyone could hear them clearly and clearly.

"Attention, attention! Scrap has murdered forty-two escorts and two power engineers! Attention, attention! Scrap has murdered forty-two escorts and two power engineers! ”

"Attention, attention! The weapon used in the scrap is a crossbow! Attention, attention! The weapon used in the scrap is a crossbow! Attention, attention! All of them are on the highest alert! Attention, attention! All of them are on the highest alert! ”

"Attention, attention! Kill the scrap as soon as you find it! Attention, attention! Kill the scrap as soon as you find it! ”

As the shrill sirens spread in all corners of the building, the first floor where there was still earth-shattering music immediately fell silent, no, to be precise, it should be, the music stopped, and all the people on the first and second floors of the entire building became extremely flustered because of the content of the alarm.

And the large number of gun-wielding and all-out martial law hooded patrollers who ran out of nowhere, further deepened the panic.

As early as when the alarm just sounded, Ding Zhu and Qin Ge, who had already deftly drilled into the air duct again, were carefully observing all the conditions outside through the gap in the exhaust of the air duct.

The hood rangers are searching almost every corner, the intensity is so great, there is no difference from the carpet investigation, but for the time being, they have not searched the air duct, so this air duct must not stay for a long time, Ding Zhu and Qin Ge can only make the next step if they quickly find the data room and complete the background clues of the characters.

Just as the two of them kept struggling to pass through the wind tunnel according to the map, the hooded rangers had already gathered all the people on the first and second floors of the ground in the hall on the first floor.

They were divided into two groups according to their gender, and exited through two doors at the entrance to the hall on the first floor.

In front of those two doors, there were already two things like huge door frames, and everyone had to use their identification card to swipe the door frame before going out, and they had to be recognized by the recognizer before they could pass through the door frame.

It would seem that this is a double-insurance inspection device.

As the people in the huge building evacuated to the outside through the inspection device, the countless floor-to-ceiling windows on the exterior wall of the building were slowly lowering what looked like roller shutters.

Countless brilliant fireworks in the night sky outside disappeared without a trace as the shutter-like thing fell.

"How far is it?" Ding Zhu couldn't quite understand Qin Ge's hand-drawn map, so when he crawled in the wind tunnel, Qin Ge led the way the whole way.

Crawling like a snake in such a narrow air tunnel is really not a good experience, not to mention, Jenny's body is really a little plump, which causes Yu Ding Zhu to be extremely tired.

"Soon, there should be two more turns and two corridors." Qin Ge led the way while carefully observing the situation outside through the gaps in the air duct. "How's the hooded man doing?"

Qin Ge was in charge of leading the way, so he handed over the actions of these hooded men to Ding Candle: "I don't know where so many popped up, I see that they are about to rummage through the land, it is estimated that if we don't leave the wind tunnel again, they will soon find here."

"Got it, hurry up, I'd like to find a shortcut."

"Is there anything else I haven't found?" Just as Ding Zhu and Qin Ge were still crawling hard in the wind tunnel, a rough voice came from behind the corner not far away.

"I've searched them all."

"Have you searched every room and corner?" The hoarse voice asked again.

"Yes, sir, we've even searched the rat holes, but we haven't found anything, no escaped scrap."

"No?" The chief's brows furrowed tightly, he didn't believe that everything had been searched, could this scrap be invisible? Or is it going straight to the sky? How could it not be. "Did you run out?"

"No, the alarm hasn't gone off."

While the chief was pondering, he suddenly saw a wire nailed against the wall, and his eyes followed the direction of the wire.

Up, up, keep up.

The wire finally sank into the roof, he was slightly stunned, and immediately realized something, he raised his hand and pointed to the renovated roof and asked, "Have you searched this above?" ”

"No, sir!"

"Check it out for me right away!"

"Yes!"

Because of perception, Ding Candle's hearing is very good, even if there is no way to hear the sound of a mouse walking by, it is not easy to miss such a rough sound.

"They've found the air ducts, how far are we?" she said. ”

"Soon, there's still about twenty meters left, and you can enter the ceiling of the data room in one corner." Qin Ge calculated very precisely.

Compared to the two men struggling through the air tunnel, it was clear that the rangers were moving much faster, and they quickly found the access to the ceiling and climbed up.

However, in addition to the air vents in the ceiling, there are also intricate wiring openings, and the rangers who go up to the ceiling will not be able to find the two people so quickly for a while, but their voices can clearly preach in the ears of the two people.

Ding Zhu and Qin Ge didn't dare to speak anymore, so they could only crawl forward quickly with a muffled voice.

Eventually, the rangers found the entrance to the air duct, and after they opened it, they turned on their flashlights and looked inside.

"Not at Gate Four."

"There's no one at Gate Three."

"Not at Gate 2."

"The No. 6 port is rusty to death, and I'm still demolishing it."

The voice of the voice was in Ding Candle's ears, and through the thin metal plate, Qin Ge was already walking the last corner, she could only put her body lighter, and did not make a sound on the metal plate.

"Can you take it apart?"

"It's a bit difficult, but no problem. Ha, it's taken apart! ”

Ding Candle, who had already crawled into the corner with half of his body, suddenly broke out in a cold sweat when he heard the other party begin to disassemble the metal plate.

"Bump!" The metal plate at Port Six was finally removed.

Ding Candle was stuck......
