The city of NY, a famous metropolis in North America, is the world's financial center with a pre-apocalyptic population of 11 million. It has a satellite city called Quinn City, which is located 25 kilometers from downtown NY, and EL's headquarters is on the outskirts of Quinn City.

A building with more than 30 floors, there is a courtyard wall in front of the building, and the outer wall is printed: ETERNAL LIFE.

This is the headquarters building of EL Biopharma.

Two Humvees, four blue and white police cars, and a convoy of military trucks smashed through the iron gate and stormed into the compound, and a group of heavily armed men, including policemen, commandos, and the Civil Guard, descended from several vehicles.

The leader was a young girl, none other than Senna.

This team of military police is composed of at least 40 people. Sena looked around, then at the building, and said, "Everyone pay attention to safety, don't get separated, as long as you see zombies, don't ask why, shoot them immediately!" Let's go in! ”

The time is now two p.m. local time.

Everyone walked to the steps with their weapons in hand, and before they had taken a few steps, they saw a zombie stretching out his hand, screaming strangely, and was immediately hit by several bullets at the same time.

Entering the hall on the first floor, he killed several more zombies.

In the center of the hall there is a very large glass booth with pictures and objects on display, which are the result of EL over the years.

Just from these can not see the hidden evil deeds of EL company, at most it can only be considered a very successful pharmaceutical company, who would have thought that the rampant zombie virus would be produced by this company?

There was a self-service computer in the middle of the booth, Senna asked everyone to strengthen their vigilance, came to the computer by herself, wiped the blood stains on it, and turned it on, this is a touch screen, Sena clicked on the link above, and one of them was a three-dimensional view of the building.

A three-dimensional structure diagram was brought up, which introduced the layout and introduction of each floor and room in the building.

After looking at it for a while, I couldn't see why, such a huge building, if you investigate it layer by layer, it obviously takes a lot of energy.

Senna carefully studied the three-dimensional layout of the subject, and remained silent, while the other soldiers and police officers searched everywhere, occasionally seeing a few zombies that broke in, and were immediately killed.

One soldier asked, "What did you find?" ”

Senna pointed to the three-dimensional layout and said, "Didn't you notice that this piece in the middle of the booth is a little strange?"

In the center of the hall, there are four walls enclosed by paintings and decorations, which clearly enclose a rectangular room.

The soldier asked, "You mean there's a problem." ”

"That's right. Let's go around and take a look. As she spoke, Senna circled around the rectangular room, followed by several other soldiers.

The four walls are long and narrow on both sides, at least ten meters long, and the two short ones are just over two meters wide. It is three meters high.

The lobby on the first floor is shaped like a patio, and you can see that there are corridors on each floor, and you can look down on the lobby below.

Turning to the side of the short wall, I saw a copy of Edvard Munch's oil painting "The Scream" hanging on the wall, which is more than two meters high and occupies almost half of the wall.

Several soldiers looked at the painting with Senna, "Don't you think there is such a painting hanging here, is it very abrupt?" Senna asked, as if talking to herself, "Exaggerated expressions, frightened open mouths and shouts, what does EL want to express?" ”

One soldier said, "Maybe there's some secret behind this painting?" ”

Senna nodded and said, "Possibly, then take it off." ”

Several people took off the oil painting together, but they were shocked to discover the secret behind the oil painting, it turned out that there was a 50 cm square glass cabinet on the wall behind the painting, and there was an electronic lock in the glass cabinet.

Open the glass door and look at this electronic lock, which says in English: Welcome to Eternal Life CO. (Welcome to EL)

Seeing this electronic lock, Sena was stunned. According to the current situation, EL's secret must be behind this electronic lock, but the password is ......

"Which of you is a computer expert, crack it!" Xena shouted.

A soldier came over a while and said, "I'll try it." ”

After looking at it for a while, he said: "No, this combination lock has three chances to enter, and if it is wrong, it will be locked for 24 hours." ”

"What about brute force?" Senna asked again.

The computer master shook his head: "No, the defense measures are too strong, our weapons can't blow up......" said and looked at the structure diagram again, "This should be a door to the underground, if it is forcibly blown open with high explosives, I estimate that the passage will be blown up, and then we will have no way to go down." ”

"Are you sure this is a passage to the underground?"

"Not sure, but only a possibility."

While Senna was worried, two soldiers grabbed a living man, wearing a white coat and a badge that showed him to be a senior member of EL Company.

The soldier escorted him over, and Senna sneered, "You're lucky not to die." ”

It turned out that he hid in a cabinet in a corner of the hall, escaped the catastrophe, and hid in the cabinet for four days with dry food and water, although he survived, but his whole body stinked to death, and it turned out that all the urine and urine were solved in that cabinet.

Senna covered her nose and asked, "Do you know the password?" ”

The man nodded in horror and shook his head again.

Sena said angrily: "You Bichi, do you know or don't you know?" ”

A soldier held a gun, pointed it at the man's head, and said viciously: "You crazy people, you have destroyed the world, now let's clean up these messes for you, you know you Bichi!" Say it quickly, or I'll kill you! ”

"I, I know......" the man said as he unlocked it, muttering, "There's something horrible down there." ”

Senna said, "You'd better listen to him and unlock it, I can't guarantee that he won't kill you if he gets angry." ”

The engineer pressed the combination lock, and it went very smoothly, and the lock was unlocked at one time, and with a click, the whole wall began to sink, and soon it all sank to the ground.

What appeared in front of everyone's eyes was a long and narrow room, this half was the floor, and the stairs that were wanted to go down for half a day, and sure enough, this was the passage to the underground.

Senna looked around and said, "Come here, everyone, listen to me!" ”

Everyone gathered around, and Senna said, "Go and drive all the cars into the hall, unload the equipment, and we will build a defensive position in this hall to prevent any threat that may be encountered at any time." ”

Then he said, "I want a commando of ten men to go down, and nine of you will come out and go down with me, and the rest will be here to guard." Hurry up and prepare, and set off in fifteen minutes! ”
