Under the ExxonMobil oil company's office building, Lin Rui and Park Dongxiang stood in the shadows of the building -- the camera surveillance device in the distance shone faintly in the dark night, and a group of heavily armed security guards patrolled downstairs.

These guards were not mercenaries from the Black Isle, but employees of the oil company's security services. In fact, the Black Island mercenaries were stationed in the vicinity of oil wells and refineries to guard against possible terrorist attacks and armed provocations. And ExxonMobil's office building, which has the potential to involve classified core areas, is still accustomed to using its own people.

Lin Rui put down the infrared telescope in his hand and said to Park Dongxiang, "Are you ready?"

"No problem. Park Dong-sang nodded, and he raised the anchor gun in his hand and threw it at the balcony on the side of the building. After the special alloy anchor hook was secured, the two of them quickly climbed up the glass curtain wall on the outside of the building.

The rubber soles of the combat boots don't make a loud noise when they step on the glass curtain wall, but rather a bit like the soft sound of the soles of the shoes rubbing against the floor on a basketball court. After climbing for a while, both of them fixed the nylon ropes on their bodies with figure-eight buckles and hovered quietly on the outside of the building. This makes them look like two spiders hanging in the dark, clinging to the glass curtain wall.

Lin Rui took out a special glass knife, which is specially used for glass cutting, and can cut very thick glass lightly. But Park Dong-sang stopped his next move in a low voice, "Be careful, check it first." He slowly took out a very small tool, like some kind of small flashlight, more like some kind of blue light lamp for checking money.

Under a faint blue light, thin fibers crisscrossed the seemingly plain glass, forming a grid about fifteen centimeters apart. Park Dong-sang sneered, "This glass is specially made, and these silk-like things in it are all some kind of fiberglass." Once broken, it will be displayed in the building's security duty center. ”

Lin Rui nodded, "Fortunately, this grid is not too dense, and we don't need to dig out a big hole." He found the location of the window and carefully circled the glass with his knife, trying to avoid the fine fibers. He taped it with tape and struck a hole in the glass.

The cut glass did not make a noise as it was stuck with the tape. After carefully removing the cut glass, a fist-sized hole was revealed in the window. Lin Rui reached in, opened the window silently, and then bowed in with Park Dongxiang.

After entering, it is the location of the stairway, and there is a camera surveillance at the corner. Lin Rui and Park Dongxiang walked slowly along the wall and hid in the blind spot of the camera surveillance. He looked down at the electronic map in his hand, glanced at Park Dongxiang, and then jumped out of the corridor with a tumbling.

According to the information, the archives of the security services are located in a right-hand room on the sixth floor of the building. They touched all the way, and after walking for a while, Park Dong-sang suddenly stopped again.

"What's wrong?" Lin Rui said in a low voice.

"There's something wrong here, don't you think this area seems a little too empty? there's no desk, no furniture, it's a little different from the rest of the building. Park Dongsang frowned.

Lin Rui looked around and found that it was indeed a little different. Park Dong-sang suddenly whispered, "Do you have any cigarettes?"

Lin Rui touched his pocket, took out a cigarette and handed it to him. Park Dong-sang lit a cigarette but did not rush away, but took a puff of the cigarette and spit it out. The air was filled with a faint smoke, but at the same time, a faint burst of smoke could be seen through the red rays of light. The red light is so subtle that it is almost invisible to the naked eye in the black, but it is distinct in the smoke.

"Infrared alarm device, part of the commercial-grade Floyd security system. Park Dong-sang frowned, "Theoretically, this is a four-level security system. Why does an oil company need such a high level of security?"

"It's no surprise that these oil giants have deep pockets in the world's most lucrative energy deal. Just winning the mining rights in this area will cost 5 billion. Their trade secrets are worth a lot of money. Lin Rui said in a low voice. "Is there a way to break through?"

"As long as you don't touch these red rays, you won't trigger the alarm. Park Dongxiang said, "But I have a better way." ”

"What way?" Lin Rui frowned.

"These red rays come from the transmitters and receivers at both ends of the wall that will sound an alarm whenever the light is blocked, but this thing is actually very low-level, and it can be blocked with some kind of special red sticker without setting off an alarm. Park Dong-sang said as he found the transmitter in the corner of the wall and dealt with it accordingly.

"Where did you learn these messy techniques?" Lin Rui frowned.

"A training camp for terrorists, I used to serve them. Evading surveillance, stealthily infiltrating, and installing explosive devices are all part of the training. Park Dong-sang said in a low voice. "Alright, I've got it. ”

"It seems that the terrorists are also moving with the times, and I thought they would only do sabotage. Lin Rui smiled bitterly.

"There is no shortage of talent in a real terrorist organization, all kinds of talent. And they have a lot of their own dirt methods, although they are very earthy, but they are really effective. Park Dongxiang said slowly.

"Alright, let's go. Lin Rui nodded. Together with Park Dong-sang, he found the reference room, then opened the door and entered, and the scene inside was somewhat like an old-fashioned archive room, with rows of iron cabinets, arranged by date and letter number.

Lin Rui rummaged around for a moment and frowned, "There are no records related to the crash in the corresponding date. ”

"It's the same with me here, I can't find all the schedules of the project leader for that date. Park Dong-sang shook his head and said, "He never seems to have this agenda." ”

"Damn it, I think someone must have transferred all the information related to this. Lin Rui frowned.

"Hey, look here, I think I understand where these things are being transferred. Park Dongxiang turned his head to look at Lin Ruidao, he opened one of the filing cabinets, only to find that there was no information inside. There is only one door, a hidden safe door
