Battlefield Contract Worker

Six thousand three hundred and twenty-eight chapters have no fear

The computer on the table made a beeping sound, and Lin Rui turned around and asked Cobain, "Is there a problem?"

"No, a cracking step has been completed. It seems that we may have good luck. Look at the wall."

Lin Rui narrowed his eyes and noticed that a part of the wall protruded out, forming a circular opening the size of the tip of his thumb. "That's a data port...or some kind of dedicated data port channel for maintenance engineers. I'm switching signals from there via shortwave and infrared reception. Take my cracked computer and plug it in there," Cobain said.

"Are you sure? It won't trigger the alarm, right?" Sergey couldn't help asking.

"Don't look at my inability to play a role in combat, but I have cracked the last firewall, and once I have a direct connection to the communication network, I can penetrate into the systems that take over them; at the same time I may be able to control subordinate systems, give You buy enough time. But it looks like you still have to get to the vault and manually get me into their control system."

"As long as you are sure."

"When am I not sure?" Cobain was a little angry. The security system was really tricky, and his impatience could be felt.

Lin Rui took out Cobain's data chip from the slot, which was a **** he designed for brute force cracking. Lin Rui inserted the chip into a hidden data port on the wall.

With a look of disgust on Sergey's face, he whispered: "This is the reason why I hate having the protection of modern technology. There are always many technologies that I don't understand. This has made our traditional craftsmanship less and less respected. already."

"Shut up." Lin Rui waved at his neck and made a slashing motion. The Russian fell silent immediately.

"Okay, I'm in," Cobain whispered.

"How is the situation?" Lin Rui asked.

Stopped for half a second. "It's...a little bit different than I thought. But it's not that big of a problem," Cobain replied.

"Okay, hurry up." Lin Rui motioned him to continue.

"This algorithm is so different from what I thought," Cobain muttered.

Cobain's cracking device was built specifically for hacking software. Every trick and code-breaking algorithm devised by U.S. Cyber ​​Command was programmed into him, and he mastered more techniques in his own right. Cobain is the ultimate thief and electronic spy. Now he has slipped into the heavily guarded security system.

I thought it would be difficult to get in, but after entering the security system for the first time, it was easy. At that time, Cobain put their monitoring system into self-diagnostic mode. This causes the system to self-check and reset the system quickly—but it already gives them valuable time, enough time to get into the vault.

"How's the situation?" Lin Rui asked. Now that Cobain's surprise was gone, the security system's anti-intrusion systems were on high alert. He stared at the screen, as if he felt something patrolling the system, as if it were using a tiny probe to probe the intruder's hideout. After probing for a while, it shrank back.

It feels like something else is roaming the system. is an artificial intelligence? The intelligence never mentioned reports of artificial intelligence being used in security systems. The possibility piqued his interest.

"Different from what I thought..." he finally replied. "The security system has a self-checking program and is highly intelligent. But AI is always AI."

Cobain scanned the code stored in the system, then quickly escaped the surveillance system, picked a path, and stored it in the third-level system cache. Have some blocks perform multiple tasks at the same time, and then proceed to analyze the structure and subsystems of the security system.

Cobain controlled all the surveillance cameras outside, and when he checked, he found a dozen armed guards sweeping the corridors. They traveled down the corridor: everyone's information was displayed on the security system.

"This security system has a subsystem, and in addition to surveillance cameras, every security guard has similar tracking devices on them. This shows that our previous intelligence was correct. The security guards here are wearing special shoes, so that you can see Accurately judge their personal situation. Once they encounter an accident, the security system will find out at the first time." Cobain whispered.

"Their routine inspection has begun. But we are in the security director's office, and they won't come in unless they have director authority." Daniel whispered. "At least for the time being we are safe. As long as there is no movement, they won't find us."

Cobain nodded, "I have control of all the cameras now. When you are moving, I can adjust the angle of the surveillance a little to make sure you are outside the surveillance. In addition, I can upload the azimuth coordinates of the guards to your tactical tablet. Come on. After they've finished their inspections, you can start moving. At this time, the monitors and sensors are set to loop.

The guards will change shifts within fifteen minutes at most, and the monitoring problem has been resolved, you just need to be careful.

"Nice job. Can the alarm be turned off? I want some security when the lock is unlocked," Sergey asked.

"Yes, but only for three minutes. After three minutes, the system will automatically restart and the alarm will resume again. So it can only be used at critical moments." Cobain replied.

"Well, it's disappointing, but it's better than no guarantee at all." Daniel sighed.

fifteen minutes

After that, the security patrol ended. After Lin Rui and his team walked through corridors and highly protected biometric scanning arches, they set foot on the passage leading to the inside of the vault.

They left Cobain in the office and closed the arch behind them. This is to protect Cobain, plus he has more ways to assist them by staying in the office.

Lin Rui and others came to the outside of the vault, and three meters to the left was a slightly curved white wall. There is no door above. Behind the wall is a highly secured vault.

"Is this the Federal Reserve Bank vault?" Sergey finally whispered. "It's a little irritating to think about. You think there will be something valuable in it."

"I don't know," Daniel replied. "Before I met you, I never had an idea here."

A door appeared on the white curved wall, and Sergey walked there. "Come here, gentlemen, here it is."

Everyone who tries to walk into the vault has to be scanned by an iris eye camera. The camera has stored the eyeball iris of each internal staff member in the vault in advance. After scanning, the computer will check the record immediately. Once the corresponding iris record cannot be found. The library door refuses to open for you, and an alarm is sounded.

But this iris scan has been turned off due to Cobain's control of the security system. Otherwise, they are really not easy to handle.

They entered the room. When Lin Rui stepped into the room, he felt a heavy sense of depression. The sunken shiny walls in the room are always disorienting. The huge round metal door is even more oppressive.

This 5-story underground vault is 25 meters below sea level, deep into the ground of New York City, 30 feet lower than the New York City subway system, and surrounded by huge granite, forming an unbreakable natural barrier on which the New York Commonwealth is built The Reserve Bank headquarters building, equipped with strict and advanced security measures, is like an underground bunker.

Now they are facing the famous "door lock" system.

In this complete "door lock" system, the door frame is a reinforced concrete component weighing 140 tons, and the door is placed in the door frame, which is two semi-circular steel cylinders weighing 90 tons and 3 meters long. There are tracks with a narrow passage in the middle. Demonstration by the staff: Through a certain mechanism, the cylinder will rotate. When it is turned to a certain angle, the two semicircular cylinders will match to form a complete circular cylinder, and the door of the vault will be closed.

This lock can be manually set for a time. After setting the unlocking time, once it is locked, the door cannot be opened until the set time.

The world's top security system, all kinds of bright and dark cameras and monitors are everywhere. It is said that since its completion in 1923, it has never been broken into. There has never been a robbery. It's not that the thieves don't want to, it's just that the security of the Fed's underground vaults is impeccable. In the face of such a strong defense system, let alone a living person, it is estimated that it is difficult for even mosquitoes to fly in.

"On the door, there are 3 locks. The keys to open them are kept by the bank management, accounting and security departments." Daniel turned to look at Sergey, "It's up to you. This lock has no key and can't be opened at all. Pick it up. Not enough time to lock. I can't think of any way to open the door."

Sergey didn't dare to be careless. He squatted down to observe carefully, and finally said in a low voice, "Believe it or not, I can open it in just a few minutes?"

"How to open it?" Daniel hesitated.

"First I want a sledgehammer." Sergey took a few steps and looked in the corridor outside. Of course there was no sledgehammer here, but he took a fire axe from the fire cabinet on the wall.

Daniel looked at him with an extremely mocking expression on his face. "You want to use this axe to split open the door of the vault. Do you want me to tell you that this thing can be a whole piece of cylindrical steel. A dozen meters of cylindrical steel, do you want to leave it with an axe?"

"Yes." Sergey walked over with the dull axe.

"You didn't really intend to do this, did you?" The Black Mamba couldn't stand it. Although he believed that Sergey must have a way, he did not believe that he would really use an axe to split the door.

"That's what I'm going to do." Sergey swung his axe down hard. Once, twice, everyone is dumbfounded. How stupid is this to do such a thing?

But soon the expressions on their faces became very wonderful. Daniel's mouth was so surprised that he could put a whole egg in his mouth, and he stared blankly as Sergey chopped off a chunk of metal with his axe, and then another chunk.

Is this broken axe some kind of magic weapon? How can you cut down a solid piece of steel?

But this is obviously a fire axe that I brought along? Daniel felt that his brain was about to lose its use.

Only Lin Rui remained silent, as if he already knew the result. "Hurry up, we don't have much time."

Sergey nodded and slashed again. The metal door of the vault was actually cut down in large chunks by him.

Daniel picked up a large piece of metal and was taken aback by it. "Well, what's going on here?"

The metal block in his hand seemed to be very unusual. When he squeezed it, it would become soft, and pieces of debris fell from his hand.

"This door was destroyed beforehand, which is why Sergey is so confident." Lin Rui smiled slightly.

"But, when did this happen? How did it become like this?" Daniel said in shock.

"A few days ago, Aladdin did it when he sent people to spy on us. They found someone to enter the vault, and when the security personnel were not paying attention, they used a

Something broke the door. Lin Rui explained. "A metal gallium. "

Metal gallium is the 31st element in the periodic table of elements. It belongs to the 3a group, which is the third main group. It is the same door as the common metal aluminum. The melting point of the metal gallium is very low, only 29.76 degrees Celsius. As long as the environment is slightly warmer, it will become a liquid metal like mercury. So people are too hot for metal gallium, and they will melt if they hold it in their hearts.

And gallium has strong adhesion and may remain on the table, gloves or skin, leaving black marks.

If liquid metal gallium is dropped on an aluminum can, it will not take long for the aluminum skin that touches the gallium to begin to thin, and it will break with a light poke.

Not only aluminum, but other metals, such as iron, copper, zinc, etc., are also "corroded" by metal gallium. A lock is dripped with metal gallium, and it can be broken open after a few hours. However, this is not because the metal gallium is really acidic and can corrode. After all, it can be placed in human hands very well. In fact, this so-called "corrosion" is related to the internal structure of the metal gallium.

The solid we see is actually a form that is maintained through energy, and solid cohesive energy is required in this process. Solids are composed of atoms, and each atom needs to release energy to unite everyone. The more energy, the harder the solid is to melt, and the higher the melting point. The atoms in many metals are very united, forming metallic bonds between them and forming a very tight unit cell structure.

But gallium did not take the usual path, and its atoms made a decision that went against their ancestors and formed a covalent bond!

The atoms in the original metal crystal are arranged in an orderly manner, which leads to a gap between each atom. When the liquid gallium is added, the unorganized and undisciplined gallium atoms will "see the gap".

When other metal atoms encounter gallium atoms, they will be "disintegrated" by the gallium atoms from the inside out, changing the structure of the metal crystal. No longer the tight crystal structure it once was.

So in essence, it is not the metal gallium that corrodes the metal, but it destroys the original metal bonds, forms new chemical bonds with them, and changes the structure of the metal crystal.

Aladdin's people secretly used the reason of renting a safe for a few days, and sent someone to explore the safe in advance, and by the way, smeared metal gallium on the door.

After a few days of reaction, it was enough to make the surface of the metal door as soft as bread. This is also the reason why Sergey and Lin Rui are confident.
