Standing at the bottom of the dusty staircase, Yi Fei and Dapeng stood and lay down in a shooting posture and stared intently at the depths of the dim and chaotic passage in front of them, and when the smoke and dust gradually fell, the two took the lead in identifying the corpse that was lying on the ground not far from them, with no signs of life, and the Northern Dynasty man who was ambushed here and preparing to sneak attack had been blurred with flesh and blood from the explosion and Yi Fei's indiscriminate shooting.

The explosion flickered the already small lighting below, and the two of them searched for it alternately, and soon, the two of them patrolled the place, and found no other threats.

The layout of the basement is similar to that of the building on the ground, but it feels that the usable area is significantly smaller than the building on the ground, and after a round of inspection, in addition to finding a few rooms here for resting and storing daily necessities, they also found a storage room for storing weapons, and then there is the control room used to monitor the entire storage area inside and outside, and similarly, the two of them did not find Feng Shaolan's shadow below.

But when he was checking the weapons storage room, the two sets of protective clothing stacked on the shelves inside attracted Yifei's attention, and the protective clothing suddenly awakened Yifei's memory, and he remembered where he had seen the special backpack that the Northern Dynasty people had taken away just now......

That is when he and Lezi received anti-terrorism training in Israel, the professional instructor had explained to them the use and use of this backpack, this backpack is a high-tech product jointly designed and produced by multiple departments of Israel, and it is not impossible to figure out how these Northern Dynasties people obtained this backpack for a while, let alone understand the meaning and use of backpacks and protective clothing appearing here, but Dapeng's urging is close to the ear:

"No, you hurry up and go to the computer room to check what valuable things can be found in the surveillance, and I'll go to that arsenal to see what is available."

"Okay, let's move quickly, this is not a place to stay for a long time, let Da Lei pay attention to monitoring, we don't let people be bored here."

After saying that, he turned around and walked into the surveillance room, and Dapeng ran quickly to the cabin where the weapons were stored at the end of the basement.

Slightly different from other rooms, the door of this room where weapons are stored is a sealed door that can be locked separately from the inside and outside directions, and it is said that this setting should be controlled by a special person and can only be opened to access the weapon after its permission, so that the arrangement is not only for security but also to facilitate system management, but the Northern Dynasty people who may have been guarding here just now hurriedly in order to deal with their two intruders, took out the weapon and directly threw themselves into the encirclement and suppression of the two people, and the door was not locked. Dapeng went in and took a cursory look, they were all ordinary weapons and ammunition, and there was nothing special that could arouse Dapeng's interest.

In line with the principle that thieves do not go empty, Dapeng took two AKs and a few magazines from a weapon rack against the wall in case of emergency, and was just about to walk back, when a certain position under his feet made a very slight 'pop' sound, which aroused Dapeng's vigilance, Dapeng looked down at a large piece of anti-static rubber pad on the ground, and his feet exerted force again, and he confirmed that the sound was coming from under the rubber pad.

The rubber pad covered almost all the blank spaces on the ground, Dapeng stepped aside, lifted the rubber pad and rolled it to the side, and after a few rolls, a cover with a folding handle and surrounded by iron frames poured with cement in the middle gradually revealed, and Dapeng immediately shouted to the other side of the non-contender:

"No, come and see, there's a secret passage here."

As he spoke, Dapeng tried to turn the handle and pull it up, but couldn't.

"That's right if there is a secret passage, don't move yet, come to me quickly, I've found something wrong here."

Hearing this, Dapeng put the rubber pad flat again, and just in case, he pressed a heavy tool box on top of the lid.

"What's wrong?"

Dapeng, who ran to the monitoring room with two assault rifles, asked while leaning down to look at the monitoring screens in front of Yifei, seeing that Yifei was engrossed in front of several monitoring displays, one hand kept tapping the control keys on the keyboard and called up the image of the location he suspected, Dapeng couldn't help but lean forward again, and when he saw Dapeng coming, he didn't adjust the position of a monitor in front of him and asked Dapeng:

"Dapeng, have you seen the two monitoring points displayed by this monitor?"

Dapeng stepped forward to stare at the two monitored screens that were divided on the monitor, took a closer look and said:

"No, these two locations are not here, is this another warehouse that they monitor?"

"No, look at this passage again, have we seen it?"

The display shows a dark and deep underground passage.

"No, but this is supposed to be the secret passage I found over there?"

"That's right, this monitoring point should be placed in the dark tunnel you found over there, when I first saw those two strange monitoring points, I thought the same as you, that these strange monitoring points have nothing to do with here, but then I looked at the monitoring of all locations in this reservoir area, especially several long-range monitoring and the monitoring in that tunnel, I found the connection between them, you see......"

The several monitoring screens in front of him show not only the implementation images of the periphery of the warehouse and the perimeter of the office building, but also the real-time image transmission of the two warehouses and different locations in the building.

"Doesn't it sound familiar from this perspective?"

"You've seen that before, isn't this the railway next to this building and the platform across from it? Damn, the people in their country are about to have food and live, but there are so many foreign red wines stored in this warehouse, how much food can be exchanged for the money to buy wine to solve the problem of food and clothing for the people, what a fucking ....... ”

One monitoring point is located right next to a large row of wine racks on the inner wall of a warehouse, densely packed with thousands of bottles of top-quality red wine from all over the world, which makes Dapeng very angry.

"That's not the point, look at the ......"

Nor is it a re-call to the surveillance of the suspicious tunnel.

"After seeing the tunnel monitoring point, I think that the mysterious tunnel is likely to connect the two warehouse locations in the shadows, so I called up the previous surveillance images in the tunnel and looked back, guess what I saw?"

Under the operation of Yifei, the time count on the tunnel monitoring quickly fell backwards, and the original unchanged surveillance image suddenly appeared a few figures, flashing from the screen like a fast action, nor quickly pressing the control key, the monitoring image stopped at this point in time and began to jump forward normally, Dapeng looked at the time display above, it should be the time period before those people walked out of the building, the monitoring continued to play, and the figures that flashed quickly just now appeared on the monitoring screen one after another, Several people moved quickly along the dimly lit underground passage, and a familiar figure appeared in the surveillance footage.......
