It was night, the moon and stars were sparse, and the cold wind was blowing, as painful as a knife scratching the skin.

The two of them had already arrived at their destination, the building, which still had a rusted steel door number, and they could still faintly recognize a few large characters on it:

Hsieh Group.

"Put this on." Lan Tian threw a camouflage uniform to Su Hao, and at the same time put on the same clothes himself.

Su Hao looked at the clothes in his hand in surprise and said, "What is this?" ”

"This is an improved digital camouflage uniform." Lan Tian's figure is very slender and slender, so it is easy to put on the clothes, he continued: "This improved digital camouflage not only has the hidden effect of traditional digital camouflage, but also uses the visual principle of pixel lattice to blur the edges between different colors, and has the characteristics of gradient in vision." Moreover, by doping special fibers, it has the effect of adjusting body temperature, and neither optical nor thermal detectors can detect this state-of-the-art camouflage. ”

"And, look at this building." With that, Blue Sky pointed to somewhere in that building.

Su Hao looked up, and sure enough, in the place pointed by the blue sky, there were actually a lot of flesh-like organs similar to ** and cell tubes, and they were still squirming, looking extremely disgusting.

"Part of this building has been hiveted, in other words, this building is now half a hive, and there are naturally a lot of bugs in it."

"Not only do bugs have a strong sense of smell, but they also rely on thermal vision for detection, and this camouflage suit not only allows the body to almost integrate with the environment, but also isolates the body and adapts to the surrounding temperature, which makes it relatively safer to be in the building."

Su Hao nodded, indicating that he understood, and then put his clothes on.

At this time, another mercenary who followed Lan Tian walked to a certain place on the wall of the building, took out a drill, and gently pried open a tile that looked extremely delicate, and then continued to pry open the building materials inside, revealing a section of line.

He took out a miniature notebook, then inserted the cable into the port, gently adjusted it, and then said, "Although there is a partial nest here, the power system and network system are only damaged, but they are still functioning normally. ”

"Did you find the secret mouth?"

"Not yet, the firewall is still intact, and it will take a while to break in."

"How long will it take?"

The guy was still working on the machine, and without looking back, he replied confidently, "Five minutes." ”

This person seems to have absolute confidence in his professional field.

Lan Tian nodded with satisfaction and said, "OK." ”

Five minutes passed, and somewhere on the ground, an abandoned lawn suddenly cracked into a square pattern, and the soil was arched open, separated from the turf, and then an alloy surface door appeared before everyone's eyes.

"According to the information given above, there are two paths to the underground research room, one is the normal way to enter the research room from the inside of the building, and the other is the secret entrance in front of you."

Su Hao frowned and said, "But why is this secret door closed?" Looking at the material of the secret door, you don't have to think that it is also the hardest tungsten alloy, and it is impossible to forcibly break it. ”

Lan Tian smiled: "Of course not, there is also an electronic screen there, which requires a dynamic password...... Although it sounds difficult, there will always be professionals to solve professional problems, don't you say, no? ”

No. 2 was the smiling young man with a miniature notebook, he wore a pair of glasses, except for the slightly ugly and murderous digital camouflage uniform, everything else, whether it was looks, temperament or anything else, was full of intellectual bookish temperament.

It is clear that he is a professional specializing in electronics, and at the same time his marksmanship is excellent.

"The one-time password changes every minute, and now it's just 15 seconds, and the password is ...... 7758521…… Embarrassment. ”

Lan Tian listened, and hurriedly entered the string of numbers, and soon, the alloy secret door opened, and a bottomless underground passage appeared in front of him.

"Let's move forward."

There is a ribbon automatic elevator on this passage, but unfortunately I don't know why, it has stopped working, and the electronic light bulbs on both sides are not lit, I think the lighting system and elevator system of this passage are different from the gate belongs to the same line. So the crowd had to walk all the way down,

The dark passage slanted downward, and everyone seemed to be swallowed up in darkness, and this feeling of constantly descending into the fall was like walking step by step towards hell, immersed in darkness, and there would be no reincarnation.

In front of me, there is another gate.

Next to the door, there is still an electronic screen, prompting to enter a dynamic password.

"Keep intruding."

Maybe it was because he had invaded once, but this time he invaded much faster, and in just one minute, he got a new dynamic password again.

"This time the one-time password is...... 2121241。 Fuji replied, he was stunned for a moment, and said, "After entering the password, you can choose to open this door within a minute, I recommend calling up the map on the first floor of the underground research room to observe it before entering." ”

Lan Tian called up the 3D map of the map with his mobile phone, and said to Su Hao: "I have completely memorized the map, but you'd better take a look, because the underground research room is completely isolated from the ground through a password door, so insects will not enter, but the virus is pervasive, and there are still a lot of staff inside." ”

"So, be careful."

Su Hao nodded.

"I'm going to type."

The door is opened.

Rumbling open, inside, is a gloom, neatly placed all kinds of mainframe computers, as well as a large number of experimental facilities.

Fuji looked around and found the switch on the lighting system, but when he pressed the switch, he found that the light was not on.

Seeing this, Lan Tian said to Fuji: "Presumably, the power system connected to the lighting system here is running out of power, so hurry up and find a backup power supply." ”

Su Hao looked around and said, "Shh...... Don't you think it's too quiet? ”

As soon as the blue sky testified, I listened carefully to the sounds around me, and found that the environment was indeed too quiet, it was really a death-like silence, except for the breathing of everyone, almost no sound could be heard, and the environment was a little too quiet.

"You just said that this is the first floor of the underground research room, so there is also the second or even third floor of the underground research room?"

Lan Tian nodded and replied, "Yes, the second floor of the underground research room is the rest room for the staff, and the third floor of the basement is the place where key items are stored, and the USB flash drive is also there." ”

"That's it." Su Hao frowned tightly, and replied with a hint of uneasiness: "If the end of the world comes, the staff will definitely have no intention of working because of their worries before the outbreak of the infected zombies, and gather on the second floor as a rest area...... Wait for death. ”

Lan Tian's supple brows suddenly wrinkled like a folding knife, and he replied, "You mean, if we want to get the USB flash drive on the 3rd floor, we have to kill the zombie staff on the 2nd floor?" ”

Su Hao nodded.

Lan Tian shook his head helplessly, took out the crossbow, and said, "There is no way, it can only be solved violently." ”

Su Hao shook his head and said: "If they are really transformed by zombies, they can only rely on instinct, so they only need to open the second-floor door remotely and make a little noise, and those zombies will take the initiative to attack, and we can ...... if we are secretly ambushing."

"Remove these obstacles."

Lan Tian was startled, and his eyes were already a little different when he looked at Su Hao. He is also smart in his own questions, but he is only reflected in the countermeasures of real-time battles, but he is not good at creating a combat environment and pre-battle layout.

But Su Hao's ...... Incredible combat responses, battle layouts, and strategic development...... It's terrifying.

Lan Tian twisted his head and said to Fuji, "Do it." ”

Fuji compared a V word, indicating OK.
