The hospitals at the US military bases are heavily guarded, and even internal staff members must check their identities when entering and exiting.

A man wearing a cleaner’s costume and a mask walked over with a cleaning truck.

But when it was discovered that someone had carefully checked the entrance and exit, and fingerprints were needed to verify the identity. The black man wearing a mask pushed the cleaning car aside.

Soon he stopped the cleaning car in a secluded place and took off the mask from his face. After opening the cleaning truck, he took out a box from the inside, and looked for the identification card on his chest carefully.

Finally, a set of thin fingerprints was taken out from the inside.

This is used by agents to forge fingerprints. This kind of finger film is very thin and can impersonate other people's fingerprints when worn on the hand, and it is difficult to be seen.

After doing all this, the black man slowly put on his gloves. Pushing the cleaning truck again, he walked out of the corner and walked openly to the security gate.

"Stop." An armed guard waved him to stop.

The black man stopped and pointed to the card on his chest, "The cleaner, responsible for the third to fifth floors."

The guard motioned for him to raise his hands, and the black man raised his hands obediently. The guard found no weapons on him, but his cleaning car could not pass the security check.

Because this cleaning vehicle itself has a lot of metal materials. The trash can, the vacuum cleaner, including the pusher and chassis of the cleaning vehicle, are all made of metal.

This thing can't pass the security check at all.

The guard frowned, opened the trash can and checked it carefully. Still nothing found.

However, to be cautious, they checked the cleaner's fingerprints.

Everyone who works here has fingerprint information. As long as their fingerprints are checked, their true identity can be determined.

When the black man pressed on the fingerprint reader, the fingerprint reader immediately recognized his identity information. Including his work ID serial number.

The guard checked his badge accordingly, "Passed, let's go in."

The black man put on his gloves calmly, pushing his cart for cleaners, and slowly walked into the hospital.

In the surveillance of the hospital security room, Linda and several other CIA agents have been staring at the surveillance.

"How's it going?" Linda asked.

"Everything is normal. Except for the internal staff, no one entered or exited. All the staff also entered and exited within the specified time period, and all of them were fingerprinted." An agent replied.

"Group leader, are we too serious? This is the internal hospital of the base, and very few people come. Except for some internal staff, these staff have also received the ban.

Under normal circumstances, they will not set foot on the second floor. Even doctors and nurses must get our consent before they can enter the room on the second floor.

What's more, the elevators and entrances on the second floor are guarded by our people. In this case, if there are assassins who can get in, it would be incredible. "The CIA agent wants to shake his head.

"Continue to stare. We don't know who the opponents are or what methods they will have. Anyway, I want to ensure the safety of those people." Linda replied.

Suddenly she seemed to think of something, "How many people came in just now?"

"There were four people who came in within ten minutes. Three of them were nurses and one was a cleaner.

The three nurses came first, and the cleaner followed them. "The agent in charge of surveillance replied.

"Where did they go?" Linda asked suspiciously.

"Two of the nurses went to the nursing office, and one nurse may be in the locker room. The cleaner pushed the car into the elevator." The supervisor replied.

"I got into the elevator, but why didn't I see anyone in the elevator?" Linda said suddenly and vigilantly.

"No? My surveillance video clearly saw him entering the elevator." The agent replied.

"But there is nothing in the elevator monitor." Linda suddenly said loudly, "How many floors does the elevator go to?"

"It should be the fifth floor. But from my point of view, no one was found at the elevator entrance on the fifth floor. After the elevator was opened, it was empty." Another monitor also became nervous.

"Immediately notify the guards, block the elevator entrances on each floor, and check them floor by floor. In addition, inform me on the second floor to strengthen guard." Linda grabbed the communicator and turned to walk outside.

"Sir, where are you going?" the two agents asked.

"I'll go to the second floor, notify the mercenaries, and notify the emergency team to join me on the second floor." Linda strode out while taking out her pistol.

Just as she hurried out of the monitoring room and walked to the elevator. A person suddenly approached her from behind, "Don't move."

Linda immediately felt something against her back. If you guessed it correctly, it should be the muzzle.

"I advise you not to mess around, there are surveillance everywhere." Linda stopped.

"This is a blind spot for monitoring. The camera at the elevator entrance and the camera in the corridor can't cover it completely. Instead, it leaves a blind spot of nearly fifteen degrees.

So from our position, no one can find us. "Wearing a mask, a black man dressed as a cleaner, pointed a gun at Linda and whispered.

"Do you know where this is? Do you really think that you can break in like this, and you can retreat all over?" Linda gritted her teeth.

"Where are the wounded?" the black man behind her whispered.

"What wounded? I don't know what you are talking about." Linda said angrily.

"Obviously you know what I'm talking about. I'm talking about Mr. K, and his two men. I know they should be on the second floor, but I must know which room they are in." The black man whispered.

"They're on the second floor..." Before Linda finished speaking, she suddenly turned around and slapped the pistol in the hands of the black man.

She moved very fast. After slapped the black man's pistol, she immediately grabbed the black man's wrist with both hands, and suddenly turned to exert force.

This is a very classic Judo back throw action. If you use it well, you can defeat the strong with the weak and throw an opponent who is much taller than her to the ground.

But just as she was about to bend down and exert her strength, the black man behind her suddenly straddled to one side.

It was this one action that made Linda's efforts to attack all previous efforts. Her hips were no longer focused, so it was easy for a black man to break free. Then with a heavy blow, she knocked her to the ground.

Linda's skills are good, but like most women, her ability to fight is not very strong. Especially the fragile positions of the back of the head and the neck and neck, and soon lost the ability to resist after being hit hard.

Linda's eyes went dark and she fell to the ground.
