The golden eagle suddenly rushed into the sky and flew towards the Black Stone Mountain.

Mu Sichen took out a notebook from the car, turned on the video, and saw the video from the camera.

Covered by dense forests, you can't see what is under the cover of the trees, you can only guess its topography from the surface, and then look for the entrance.

But on the surface, it also shocked them.

It is difficult to observe with the naked eye, but Gu Yunnian uses a special camera given to her by Mu Sichen, which can not only shoot pictures, but also night vision, infrared sensing and infrared heat source imaging.

At this moment, in the video, they saw a dense interweaving of infrared rays. If they slipped up like this unsuspectingly, they would be the first to be discovered.

The infrared rays all over the mountains and forests, I don't know what other defensive guards, such a big stroke, to say that this black stone mountain is fine, the ghost doesn't believe it.

Obviously, the institute they are looking for is in this.

In addition, there are three places in the video where the image of the heat source is slightly different from the next one, and in their experience, this is either the entrance or exit, or the ventilation.

Everyone looked at Gu Yunnian in amazement, and only a flying bird like a golden eagle would not attract their attention if it passed above the Black Stone Mountain.

If they drove a helicopter to investigate, they couldn't detect anything, and before they got close, they were discovered at the first time.

The golden eagle circled around the Black Rock Mountain, and finally raised its body and flew as high as possible, giving a panoramic view from the sky above the Black Rock Mountain.

"That's it!" Mu Sichen said, at the same time, his fingers jumped quickly on the keyboard, edited the pictures in the video taken by the golden eagle, and zoomed them out to one side of the screen, and on the other side, there was a satellite map of Black Rock Mountain, and there was nothing unusual about the daytime picture.

Gu Yunnian glanced at it, curled his finger to his mouth and blew, and the golden eagle flew back.

At this time, Mu Sichen also processed the pictures and worked out a route for surveying.

"We go up the hill from here, we get to this vent, we go in through the vent." Mu Sichen zoomed in on the map and pointed to a cliff.

When Mu Sichen switched pictures, Gu Yunnian had already seen that the three heat sources in the research institute were abnormal, all of which were vents, all of which were in hard-to-find places such as cliffs, and they had to be hung down from the cliffs, and if they were not careful, they would fall off the cliffs, and there would be no bones.

But the good thing is that the defenses here are not too big, and they are too confident that no one will easily find the location of the vents.

The mountains are full of infrared rays, and if someone approaches, they will be spotted as soon as possible.

If it is an aircraft survey, it is easier to cover up.

They only didn't expect such an accident as Gu Yunnian.

Mu Sichen looked at Gu Yunnian, "Can you?" ”

The mountains are full of infrared rays, and if you don't touch them, you will be discovered.

And this road is steep and steep, and it is a path with the least infrared light that he deliberately selected to avoid the detection system.

"No problem!" Gu Yunnian wrote down the route, and she was actually more familiar with the mountains and forests than the city.

Mu Sichen asked everyone to bring their weapons, he brought more notebooks, Gu Yunnian brought her medicine and first aid tools, and finally put on infrared imaging glasses and walked to Black Stone Mountain.

The mountain road is steep, and everyone in the group has the ambition to protect Gu Yunnian together, and no one thinks she is a burden and a drag.

But seeing that Gu Yunnian was small, walking on the rugged mountain road, walking more easily than them, he was dumbfounded.
