The system is the king of the counterattack master

Larson opened his mouth wide, but in the end he didn't say a word.

Han Xiaodong returned to him, handed the box in front of him, shrugged and said, "Why don't you try it too?"

Larson looked at the box in front of him in disbelief, moved his mouth a few times, but only said one sentence: "This is impossible!"

"Then you can change to another box and pick it here, but if you can't pick anything other than these boxes, then the alarm will definitely be triggered."

Han Xiaodong put on an expression of watching the excitement, obviously he has solved the puzzle, which still gives him a great sense of accomplishment.

On the other hand, Larson is not in such a good mood. This matter has completely exceeded his cognition.

He couldn't understand why the specially treated boxes would suddenly fail, and according to Han Xiaodong, only these boxes seemed to be disabled, and other items in the warehouse didn't seem to be affected.

"Oh! By the way, I remember Eriksson once said that you did a test after the incident, and the security system did not make any mistakes. Did you use these boxes for the test?" Han Xiaodong suddenly remembered something very important matter.

Larson shook his head: "There is no need at all. The security system at the gate is the most advanced metal detection device. Didn't we hand in all the metal objects on our body before we came in? It is to prevent the alarm from being triggered, so just need to Take a metal object like a key through the gate, and the alarm will sound, which can prove that the security system is not broken, and there is no need to carry the boxes for the experiment, and these boxes are also physical evidence and cannot be moved at will."

With such a simple test, Han Xiaodong couldn't help but sigh in his heart, but thinking about it, it's not a problem.

Since metal objects can be detected, it means that there is indeed no problem with the system, and, according to his guess, even a complete detection system cannot stop the gang of thieves.

"I see. It seems that we have to talk to Eriksson. This is a discovery we haven't seen before." Han Xiaodong said, carrying the suitcase, and was about to walk out the door.

"Ah, wait, this box can't leave the warehouse. You can't take it out without a bill of lading." Larson looked at Han Xiaodong with some embarrassment.

Looking at the suitcase in his hand, Han Xiaodong was a little helpless. In the end, he put the suitcase back to its original position. Since there were regulations, he had to follow the regulations, and he didn't want to cause trouble.

Now, this discovery solved his second question, but how those thieves broke through the security system was still a mystery.

Although the parts are not very large, it is definitely not a small number when faced with more than 100 such parts. Therefore, if you want to take them out of the warehouse, you must have a reasonable path. From the analysis of the video, this so-called The reasonable path must be in the corridor.

Since there was no way to take the box away, Han Xiaodong had no choice but to call Larson and they walked around the corridor together.

This warehouse is very large. There are four rows of warehouses in parallel, with 24 rooms in each row. Han Xiaodong and the others are located in Room No. 19 in the westernmost row.

It is at a relatively rear position. If you want to take things away without anyone noticing, you have to turn off all the monitoring.

The corridor was very straight and wide enough for six people to walk side by side. The two checked all the cameras and their corresponding positions one by one.

When he came to the end of the corridor, Han Xiaodong suddenly stopped. He squinted his eyes and looked at the horizontal corridor connecting the four rows of passages, thinking.

Seeing that he wasn't leaving, Larson also stopped and began to observe the surrounding environment, but after looking for a long time, he didn't see any clues. After waiting for a while, he couldn't help asking; "Is there any problem?"

Han Xiaodong touched his nose, eyes still squinted, he looked at the deep corridor, as if he could see the secret inside.

"Does each warehouse have its own exhaust?" Han Xiaodong asked suspiciously.

"There are all of them. Why do you ask this? You don't think they come in through the exhaust vents, do you? It's impossible!" Larson shook his head and denied this idea without thinking about it, and then explained:

"This is the basement floor, and the air vents come down vertically from above. If they want to go through the air vents, they have to climb up along the unsupported air duct, which is more than ten meters high. , and those air ducts are not only smooth, but also very wide, even if a person stretches out his arms, he can't support the sides."

Han Xiaodong understood what he meant. Climbing with both hands supporting the wind tunnel is a climbing technique, but if the width of the wind tunnel is larger than a person's arm span, it is impossible to use it as a support. Can't go up.

"What if the rope is left in advance?" Han Xiaodong proposed another possibility.

"It's unrealistic. First, there are fast-running fans at the air duct. In order to supply the exhaust air for the three-story underground and two-story above-ground buildings, the speed of those fans reaches thousands of revolutions per second, and a protective net is added. Come on, even if you come in, an infrared alarm system is installed in the main air duct, let alone a human, even a bigger mouse, it is impossible to escape those intricate infrared rays, this is the highest level of defense, so go to the wind It's not realistic at all."

Larson spoke confidently, but Han Xiaodong didn't take his confidence seriously.

He walked forward first, turned right in the next corridor, and entered the second parallel corridor.

"Open the door." Han Xiaodong said, pointing to the warehouse marked with No. 48.

Larson didn't understand what he meant, but he entered the code and opened the door.

Han Xiaodong discovered that the password Larson entered was the same 19-digit password he had entered in Warehouse No. 18 just now. It seemed that these warehouses either used a unified password, or each had their own unique password.

The layout of warehouse No. 48 is similar to that of No. 19, but the container is obviously larger than the latter, obviously storing larger items.

Han Xiaodong didn't care about the things in the warehouse, but walked straight towards the vent.

There are eight air vents in the entire warehouse, all installed in the ceiling more than nine meters high, and at first glance, it is impossible to climb up.

But when he saw the sixth vent, Han Xiaodong suddenly stopped in his tracks.

"Help me get a ladder." Han Xiaodong said to Larson.

Larson looked left and right, and finally found a herringbone-shaped ladder beside a container. He held onto the ladder and let Han Xiaodong climb up.

After carefully observing the vent for a while, Han Xiaodong climbed down from the ladder, pointed to the vent above his head and said to Larson, "Go up and have a look yourself. If I'm not mistaken, they should come in from here. out of here again."
