Seeing that Zheng Yin's face was becoming more and more ugly, Tian Guangliang, who had been paying attention to him beside him, couldn't help but walk forward quickly at this time and asked, "Professor Zheng, what's wrong?" ”

Zheng Yin stared at the screen intently at this time, his ten fingers kept tapping on the computer keyboard, and he didn't pay attention to Tian Guangliang directly, and after about ten minutes passed, Zheng Yin turned his head with a solemn face, and said solemnly to Chu Han: "I have to tell you a bad news, maybe we can't open the entrance and exit of the underground cold storage." ”

Without waiting for Chu Han and them to ask the reason, Zheng Yin directly explained: "Originally, we thought that we had a password that could open the entrance passage, but after checking just now, I found that the entire system, if it is to be fully opened, requires a total of three passwords, that is to say, in addition to the password in our hands, there are two additional passwords on the grain depot management side, and only by entering these three passwords at the same time can we open all the shipping channels of the grain depot!" ”

"And if that's the case? How did the staff of the grain depot enter and export the goods before? Chu Han asked curiously at this time.

"As far as I know, the electronic operation system of the entire grain depot is actually a very strong security system, and it has many passwords. Like the staff of the grain depot, they will have an additional decoder, and the password that is opened through the decoder is different every time they work, and it is said that it is sent directly from the Yanjing General Section. But now, even if we find the decoder, we can't do anything, because the password of the decoder is the signal of the Yanjing General Branch received through the network, and the decoding password of the Yanjing General Branch changes once a month. In addition, there is another way, even if you enter the three ultimate passwords, which are the three I mentioned earlier, which is a backup way to prevent the enemy from blocking the network in the event of war. And we're on hand. Only one of them is owned, and the other two are in the hands of the management unit of the grain depot. Zheng Yin quickly explained.

"Can you decipher these codes?" Guan Yu interjected and asked.

Hearing Guan Yu's words, Zheng Yin shook his head and said helplessly: "No, this system itself is the latest scientific research achievement, the so-called ultimate password, I heard that there is only one chance to enter, if you enter it incorrectly, the whole system will be automatically closed." The entire underground space is completely sealed, and if there is any further behavior to crack the system, then the self-destruct mechanism will be activated! ”

"It's so troublesome, it's really a ring and a ring!" After Chu Han listened, he sighed in his heart and said.

After Tian Guangliang listened, he shook his head dejectedly, and then asked without giving up: "Professor Zheng, is there no other way?" ”

After Zheng Yin listened, he shook his head with a wry smile. As far as he knows, this control system is the latest achievement of the Military Research Department, and even in the world, it is the number one control system in the platoon. If you want to crack it with your current technique, it will be very difficult, not to mention, he is still alone!

"Does this really have to be carried up in boxes?" Guan Yu said a little speechlessly. He doesn't care too much about whether he can transport it away, and it's good to be able to transport it away. Not being able to transport it away is not a bad thing for him!

"By the way, Professor Zheng, if you can't open it now, can you find the specific location of the cold storage inlet and outlet?" Chu Han suddenly asked at this time.

Zheng Yin thought for a while, then turned around and slapped on the computer a few times before turning his head, nodding to Chu Han and saying, "Yes, actually, it's more than that!" The password in our hands is not useless. Let's put it this way, we compare this control system to a villa, and this password in our hands is the key to the door of the entire villa, only by entering our password first, the ultimate open device of the whole system will be opened. In fact, with this password, part of the permissions are opened, and only the two core doors need the other two ultimate passwords! So, at this point, we can do something about the system! ”

"In that case, Professor Zheng, you enter the first password first and see if you can find out the specific location of the shipping port, and then we will consider the others." Chu Han was the first to speak at this time.

After Zheng Yin listened, he didn't hesitate, he seemed to see that everything here was headed by this young man named Chu Han. Therefore, after hearing Chu Han's command, Zheng Yin immediately quickly unlocked the first system permission, and then, on the screen, a huge three-dimensional display map appeared in front of everyone's eyes, and then rows of data were highlighted next to the display map.

"Found it!" At this time, Zheng Yin, who had been carefully observing the information on the screen, suddenly shouted excitedly.

"The location of the incoming port is in the No. 18 granary, and the location of the outlet is in the No. 24 granary."

"By the way, Professor Zheng, I remember you just said that there seems to be a self-destruct device in there, right?" Chu Han asked again.

Zheng Yin nodded, and then said, "That's right, in this set of devices, there is a self-destruction system device!" ”

"Can you turn this device off?"

Zheng Yin didn't answer immediately, but thought quietly for a while, and then said: "It's impossible to shut down, but there is a way to lift this self-destruction restriction, and that is to cut off the power supply to the entire grain depot!" Not only the power supply through the solar conversion system, but also a battery hidden in the shadows, which is the backup power supply for the computer at critical moments, in case the power supply system is damaged, the system cannot turn on the self-destruct device. ”

"Can you find this battery?" Chu Han asked solemnly.

"Yes!" Zheng Yin replied categorically at this time.

Then, Zheng Yin began to follow the pipeline and carefully probed the layout here, and Chu Han, soon, Zheng Yin returned here happily, and said excitedly: "Found it!" ”

"So fast?" Chu Han asked in surprise, he thought that this kind of thing would be very slow, but he didn't expect it to be found out so quickly, but this is fine.

Soon, under the leadership of Zheng Yin, everyone came to a small room, but the difference was. With a bed, a TV, and a futon, it looks more like a place to live.

"Here?" Everyone looked at the small room with some confusion and asked curiously.

"Yes, that battery, that's the bed, or rather, the bed. In fact, the reason why I was able to find it so quickly was because I was more familiar with the thinking of this circuit designer, and after my research, I found that the circuit designer in this place should be a former classmate of mine. That kid has always paid attention to the concept that it is dark under the lamp! So, what he likes the most is to hide some important things in some seemingly ordinary utensils. You see, the four steel legs of this bed seem to be fixed to the ground, but in fact, the innermost corner is actually hollow, which is the circuit line of the battery. Through there it extends underground. Zheng Yin said with a sigh at this time.

"Hehe, the most dangerous place is the safest place, indeed! Well, now that I've found it. So what can Professor Cheng tell us about how to stop the self-destructing system? Chu Han asked again at this time.

"It's simple, while cutting off the circuit. Just wreck the battery and you're good to go! ”

"In that case, it's easy to do, Yingtong, you ask Professor Zheng to take you to the place where the circuit is cut, I'm here to prepare to destroy the battery, and then we'll do it together!" Chu Han immediately said to Qiu Yingtong beside him.

And before Zheng Yin left, he solemnly instructed Chu Han and said: "Mr. Chu, when you do it, you must use all your strength, this small bed doesn't look thick, but the hardness is definitely beyond imagination, although my classmate pays attention to the darkness under the lamp, but in the same way, he will minimize the danger, so the material of this bed is definitely not ordinary." ”

Chu Han nodded, and then watched Zheng Yin walk out of the city with Qiu Yingtong, and not long after, a delicate whistle suddenly came from outside, and Chu Han knew that it was the signal released by Qiu Yingtong to do it.

The golden long sword condensed in Chu Han's hand in an instant, and then slashed heavily at the bed board in front of him.

"Bang!"

With a bang, the original intact small bed was torn apart in an instant, shattering into several pieces. Then, Chu Han walked out of the room quickly, came to the control room, and looked at Zheng Yin: "How is it, Professor Zheng, has it succeeded?" ”

Zheng Yin nodded: "It's successful!" The computer control system has not been restarted, which means that the whole control system has been disconnected! But in this case, how do we open the entrance and exit channels? ”

Chu Han smiled and said lightly: "I can only break the door violently, let's go!" ”

After walking out of the control room, Chu Han found that in the distance, some people had already begun to transport grain out of the granary non-stop. However, the grain was hit into the car and did not get on the plane.

Soon, with everyone, Chu Han came to the eighteenth granary first, looking at the empty and huge granary, Chu Han's palms suddenly slapped to the ground. At this time, countless cracks suddenly appeared on the ground that was originally covered with concrete, and then a smooth iron plate revealed a trace of cracks.

Seeing this, Chu Han stepped forward, gently pushed away the shattered concrete here with his foot, and then looked at the smooth iron plate, and a golden long sword appeared in his hand in an instant, and then suddenly fell down.

Immediately afterwards, he drew a large circle on the ground with a golden sword, and after the circle was finished, I saw that the part of the circle suddenly fell, and a huge hole appeared here, but at this moment, it was pitch black below.

At this time, a searchlight suddenly appeared in Chu Han's hand, and then he opened it and shone towards the entrance of the cave, and sure enough, there was a huge space below.

Seeing this, Chu Han changed to the diameter of the cave as the center line, and cut it to both sides, and at the same time, his body suddenly jumped into the middle of the hole, stuck the hole, and pushed hard to both sides.

"Boom"

With Chu Han's continuous exertion, the ground centered on the entrance of the cave where Chu Han was really slid quickly to both sides.

"Open it for me!"

In fact, if you want to push away these two pages of iron plates, the amount of force required is beyond imagination, even Chu Han, who is a fifth-order person, has used all his strength at this moment. With the iron plate, the internal pulley rolls faster and faster.

Chu Han instantly decomposed a drop of divine dragon spirit blood in his body, increased the amount of force to the maximum, and at the same time pushed the iron plate out to both sides.

And the ground that was originally moving slowly suddenly opened up to both sides, and a huge underground space appeared in front of everyone's eyes, and at this time, Chu Han, who pushed away the iron plate, also fell quickly at this moment, and Qiu Yingtong, who had been watching from the sidelines, immediately jumped down at this time, spread his wings, and caught the falling Chu Han, and then the two fell to the ground gently.

At this moment, huge freezers appeared in front of everyone's eyes. It's just that because they cut off the power just now, some places inside are still relatively dark, and the light is not too bright!

It seems that these are the large freezers in Guan Yu's mouth! Chu Han looked at the large freezers one by one, and thought to himself. (To be continued......)
