At this time, the two were in an underground parking lot on Chaoyang Road. The place is a bit out of the way, there are no people, and the environment is relatively dim. Xu Liang turned off the car, turned off the lights, and waited for a while before discussing the plan of action with Duan Han.

These two people have seen a lot of wind and waves in normal times, and no matter how well-defended the facilities are, there are loopholes. However, this time it was not the scene of a big battle.

Institute of Hydrological Sciences.

Xu Liang has never really touched a scientific research institution like this.

And today is a special situation, and time is very tight. They didn't have time to pick up the relevant operating equipment at warehouse 2 in the neighboring area. In order to interfere with the orientation personnel, Duanhan usually needs to prepare things including intrusion equipment, communication jamming equipment, video image camouflage equipment, etc. So this time, Xu Liang decided to let Duan Han follow him to act.

The two entered together.

This is also one of the very few positive actions that Duanhan can participate in. It also makes it easier for her to operate the equipment and analyze samples.

The two finalized some more details, and when the task was almost arranged, Xu Liang's tone suddenly became serious, and he no longer joked and amused.

He said: "Are the samples ready? ”

Duan Han lifted two plastic pockets for air and a bottle of seawater.

Xu Liang: "Have you memorized the retreat route?" ”

Duan Han nodded, and took a pen to draw the direction of a simple retreat route map.

Xu Liang: "So what is our goal in the last point?" ”

Duan Han sighed and replied, "Analyze the cause of the tsunami." ”

Xu Liang: "Wrong. The goal is to leave safely! ”

Duan Han was still a little excited, because it was also one of the few opportunities for her to participate in the mission. But Xu Liang's serious tone made her serious too. Xu Liang: "Don't underestimate any action!" We're not in the army, we're just two of us. No substitutions. No matter who is missing, the work will not be able to be done in the future. All have to be unemployed. Lift your spirits when you go in! Hear no! ”

Duan Han whispered, "I know." ”

Xu Liang: "Also, you must listen to the command." Do whatever you want, not on the beach during the day. ”

"Let's go!"

……

……

It's ten o'clock in the night.

In the National Institute of Geophysics and Hydrology, it is already pitch black. Except for the light in the reception room at the entrance, there was no light in the entire courtyard, as well as the entire building. Normally, it is common for a research institute of this level to work overtime to conduct experiments, but it is rare for this kind of collective to leave work.

This happened to be convenient for Xu Liang and Duan Han.

The two men effortlessly opened the garage door and walked down to the gate. The main building is locked at this time, and the electronic lock is used, which requires remote control or pressing the switch from the inside to open the door.

Xu Liang looked back at Duan Han and waved his head: "You can do it?" Can it be solved in 30 seconds? ”

Duan smiled coldly.

She can see that Xu Liang is lazy, and she has to let her do things that she can do by herself!

Duan Han didn't speak, and took out a shabby-looking ...... A device similar to a remote control for an air conditioner.

Xu Liang was curious. The two have been working together for so long, and he hasn't seen much of the old end in the working state, or in other words, they are all connected through built-in headsets and wireless communication in the working state, which is rare. He took a closer look at the remote-like device in the old man's hand.

This is a very simple "low-tech device", and the era of technology is about the seventies and eighties of the last century. The remote control is off-white and has only two buttons on it. Lao Xu can see clearly, and the two buttons are very conspicuous.

The blue one is "on".

The red one is "off".

Nope.

A large remote control, a total of two buttons.

Xu Liang didn't understand: "Old man? ”

The old man didn't speak, and clicked the remote control at the door locked by an electronic lock in front of the two of them. She clicked the blue button "On".

And then...... And the door opened.

It's on!

Xu Liang was stunned!

This thing...... Is this a remote control? What brand of remote control?

"Old end? New products? You've just recently researched it? I didn't even know you had this. I've got a lot of tools in hand! ”

The old man's face was grim: "Hmm." ”

Xu Liang looked at the old man's hanging appearance, this girl! Say she's fat, and she's gasping!

……

The two of them entered through the door, and when they first stepped into the first step, Xu Liang was already keenly aware of the two cameras in the hall, the left and right sides of the hall were corridors, and from their current position, they could also see the cameras flashing red at the end.

There is no doubt that these cameras transmit data through the CCTV surveillance system, some of which goes to the hard disk and is stored as video data for three months to a year, and is also sent to the security room for real-time monitoring by security personnel.

(In fact, in places like the institute, because the level of science and technology is too high, the general secrecy measures do not need to be done too well.) The security level of most research institutes is actually very average, far less than that of a bank or a museum with important collections. Typically, a sufficient number of cameras are sufficient to meet security needs)

As a super-level thief, Xu Liang's best skill is also to deal with cameras. He has at least a dozen or more ways to deal with cameras. But this time, since Duan Han has been brought in, the labor force should be squeezed.

"Can you handle these cameras?"

Duan Han: "Hmm. ”

Xu Liang glanced at her worriedly: "I can remind you that these cameras are not that simple. The one with the brighter red indicator light at ten o'clock on your side is the high-definition version of the camera, I once stole one back, and the lens turned out to be made by Canon, and one is worth 70,000 or 80,000. The camera at two o'clock, the base is round, generally speaking, an infrared camera device is installed, this camera is the latest product, a thermal imaging recorder, as long as we get a little closer, there will be data recording. Be careful. ”

Duan Han: "Hmm. ”

Xu Liang: "Are you listening carefully?" It's all my experience. ”

The old man didn't speak, and picked up the remote control again.

Xu Liang......

The old end pointed at the high-definition camera at ten o'clock and pressed the red button "off".

The high-definition camera indicator is off!

The old end pointed at the infrared thermal imaging recorder camera in the direction of two o'clock and pressed the red button "off".

The indicator light of this one is also off!

The old man said indifferently: "Now there are two corridors on the left and right, which way shall we go?" ”

Xu Liang looked at her holding a fool-type remote control in her hand, and looked confused.
