Lu Ming's shout broke the tranquility of the evening. There was immediate movement in the heavily guarded base. A group of patrolling guards quickly ran over, and several of them had even raised their firearms.

After seeing clearly that it was Lu Ming, the leading guard breathed a sigh of relief, saluted and asked, "Chief Lu, what happened?"

"It's okay. No, you go prepare the helicopter, immediately! Now!"

Realizing that the situation was urgent, the leading guard hurriedly said yes and left immediately.

At this time, both He Wei and Zhang Dingshan's room doors opened. The two of them looked at Lu Ming solemnly.

"What's wrong?"

Lu Ming looked at He Wei: "I want to conduct as detailed an investigation as possible on the Nanli Laser Research Institute. I want to know what they are doing, but I must not alert anyone there. What should I do? By the way,

It is assumed that the people inside are on high alert."

He Wei only thought for a moment and immediately replied: "In this case, I will use a large number of drones to conduct reconnaissance from high altitude. As long as the altitude is raised to more than 300 meters, there will be no sound from the ground. We have special drones.

Man and machine, at this height, can..."

"Okay, that's it! Come with me quickly, bring more drones like this, bring more drone pilots, and bring more guards, let's go!"

"Lu Ming, what happened?!"

"It's too late to explain. Come with me! Hurry! If it's too late, I'm afraid it'll be too late!"

Sensing Lu Ming's eagerness and solemnity, the two of them did not hesitate any longer and immediately followed Lu Ming's footsteps while giving orders.

Hurrying to the place where the helicopter was parked, a few people saw that the place had become a mess. Hundreds of guards and drone pilots rushed over in a queue, while logistics personnel moved over one big box after another.

There was no time to open it, so it was piled directly inside the helicopter.

In less than ten minutes, everything was ready. Lu Ming and the other three also jumped on a helicopter and immediately took off with a roar.

Until this moment, Zhang Dingshan, He Wei, and the many guards didn't even know where they were going or what they were going to do.

Lu Ming pulled up a high-precision map, looked at it, and directly pointed his finger on a point: "Go here!"

Zhang Dingshan looked over and saw that it was a relatively gentle place in Nanli Mountain.

But there is nothing here, and there are no buildings. It doesn't look like it is valuable at all.

Zhang Dingshan didn't hesitate at all, he took the communicator directly and ordered: "Move to the following coordinates!"

Lu Ming also shouted: "Except for the drone pilot, everyone else is wearing equipment, the same equipment as during the encirclement and suppression battle a few days ago! Put it on now! Pilot, prepare the drone!"

So, even on the helicopter, the guards brought all their equipment with them. The same was true for He Wei.

The helicopter flew at full speed, and in just a few minutes, it arrived at the open space that Lu Ming pointed to. The helicopter landed with a roar, and all the guards jumped out.

"Lu Ming, what should we do next?"

Lu Ming looked at He Wei: "Take people and lurk to the Nanli Laser Research Institute, and then wait for the next order! Note that there may already be a gathering place for monsters, so be careful and stay hidden so as not to be caught by them.

Discover!"

He Wei was surprised: "Monster gathering place? What do you mean? Aren't all the monsters killed?"

"It's too late to explain, go quickly!"

"Okay, half an hour at most!"

Only then did Zhang Dingshan realize that the place chosen by Lu Ming happened to be the closest place suitable for a helicopter to land without disturbing the Laser Research Institute.

"Lu Ming, why do you say that the Nanli Laser Research Institute may have become a gathering place for monsters? What did you think of?"

"I thought of a possibility within the scientific system that could completely explain this incident."

Lu Ming wiped the sweat from his forehead with some trembling, and said in a trembling voice: "This portends terrible consequences. What I am doing now is to investigate the situation and verify this idea.

Captain, the logic here is very complicated, and I can't explain it clearly in a short time. Now, let's investigate it first. I hope my guess is wrong, I hope it is wrong...

Are the drones ready? Okay? Okay, captain, go and command the drone formation, be careful not to disturb them..."

Lu Mingyue took over and issued the order directly on Zhang Dingshan's behalf. Zhang Dingshan's face was solemn, but without any hesitation, he directly passed Lu Ming's request as the on-site commander.

At this most urgent moment, he chose to trust Lu Ming without reservation.

Dozens of silent large-scale multi-rotor drones took off with a roar and quickly flew into the high altitude. The sounds they made quickly became smaller until they could no longer be detected.

At an altitude of several hundred meters, these drones quickly rushed towards the Nanli Laser Research Institute, and within a short time they had reached the sky above the research institute. The investigation began.

It is already night. The lights of these drones have been turned off, and they are at an altitude of hundreds of meters. They are impossible to see with the naked eye. Moreover, these drones are silent models, so there is no need to worry about the sound being heard at this distance.

arrive.

Facing the Nanli Laser Research Institute, which is located at the highest point of the surrounding terrain, using drones to conduct reconnaissance from a higher place is indeed the best method.

Dozens of drone pilots gathered together and concentrated on controlling the drones. The images they sent back also occupied dozens of screens.

A map was displayed on the screen in front of Zhang Dingshan and Lu Ming. There were dozens of red dots on the map. Lu Ming knew that each red dot represented a drone. Which drone he wanted to use

As for the angle of view, select it and the picture it takes will be displayed on the screen.

At this moment, Lu Ming chose a drone located above the center of the research institute and opened its screen.

Under the cover of night, the Nanli Laser Research Institute photographed with a low-light lens was clearly visible. Then Lu Ming saw that the projector array that he had placed there to project pictures of the Magic Eye galaxy on the cliff had now disappeared.

.

After our mission was completed, these projectors were disposed of by the Laser Research Institute. Now, I don't know where they took these projectors.

Lu Ming's expression became more solemn.

He was thinking hard and quickly. At this moment, he was so focused that he didn't even notice the sweat flowing into his eyes.

Even though Zhang Dingshan had millions of questions in his mind at this moment, he wisely chose not to disturb Lu Ming.

Lu Ming was carefully observing the situation inside the Laser Research Institute.

He saw that there was nothing strange inside the institute.

The street lights were on as always, and most of the room lights in the institute building were off, with only a few rooms still on.

After all, it is already off-duty time, so it is normal for most rooms to turn off the lights.

There were people walking slowly in the courtyard, some coming out of the building, and some going in. The number of people was a little smaller, which was normal.

No matter which angle you look at it, everything here is normal.

"Can a drone directly capture the scene inside the room in the research institute building?"

"able."

The leader of the drone pilot team immediately replied: "As long as you find the right angle, even if the lights are turned off in the room, the low-light lens can take pictures. Not only that, if someone is talking inside, the drone can also eavesdrop."

"

Lu Ming was surprised.

It is understandable that the picture was captured, but the sound was eavesdropped. How is this possible?

There are several hundred meters between them, one is on the ground and the other is in the sky.

The person in charge quickly said: "Sound waves will cause the glass to vibrate. The laser seismometer on the drone can capture this vibration of the glass in real time, and then through decoding, it can be restored into a sound that we humans can hear."

"Okay, check room by room. If you detect anyone there, report it immediately."

"yes."

Lu Ming originally thought that the results would come out soon. After all, even if it was off work at this moment, there should be many people in the building.

But what was unexpected was that after more than ten minutes, no one reported it.

The leader of the pilot team said: "Excluding the windowless rooms inside, there are a total of 136 rooms in the institute building. So far, 89 rooms have been investigated, and no human figures have been photographed, and no sounds have been captured."

"Not even in the room with the lights on?"

"No."

"Continue investigating."

"yes."

The drone finally surveyed all 136 rooms in total. The final result turned out to be that among so many rooms, only one room had people in it.

Lu Ming immediately recognized this room.

Before, when the projector array was being set up in the Nanli Laser Research Institute, Lu Ming had been in and out of this room many times.

It is the control room of the institute. The staff of the Laser Institute can control the operation of various instruments and equipment here and monitor their status.

Lu Ming gave the command to switch the screen, so the picture taken by a drone facing the room was displayed on the screen.

It was a room with the lights turned off. In the room, only the light from the display screens provided light to the room, and reflected the faces.

There were dozens of people sitting in front of dozens of computers and busy operating them. There were also a few people standing there quietly, as if supervising the work.

"This is the sound that was monitored."

The sound restored by detecting the vibration of the glass was played.

Lu Ming heard the sound of typing on the keyboard, but there was nothing else.
