Lu Ming's shout broke the silence of the evening. In the midst of the heavily guarded base, there was immediate commotion. A group of patrolling guards came running quickly, and several of them had even picked up their guns.

After seeing clearly that it was Lu Ming, the guard who was the leader breathed a sigh of relief, saluted and asked, "Sergeant Lu, what happened?" ”

"It's fine. No, you go and prepare the helicopter, immediately! Right now! ”

Sensing the urgency of the situation, the guard led by him hurriedly answered yes, and then left immediately.

At this time, the doors of He Wei and Zhang Dingshan were opened. The two looked at Lu Ming solemnly.

"What's wrong?"

Lu Ming looked at He Wei: "I want to conduct the Nanli Laser Research Institute in as much detail as possible, I want to know what they are doing, but I must not alarm anyone in there, what should I do?" By the way, let's say the people inside are already 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 reconnoiter from high altitudes." As long as the altitude is raised above 300 meters, there is not a single sound from the ground. We have specially built drones that can ...... at this altitude"

"Alright, that's it! Come with me, bring more of these drones, more drone pilots, more guards, go! ”

"Lu Ming, what the hell is going on?!"

"It's too late to explain, come with me! Fast! I'm afraid it's too late! ”

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

Hurriedly came to the place where the helicopter was parked, and several people saw that it had become a mess. Hundreds of guards and drone pilots rushed over in a queue, and the logistics staff moved one large box after another, and they didn't even have time to open it, and they were piled up directly into the helicopter.

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

Until this moment, Zhang Dingshan and He Wei, as well as many guards, didn't even know where to go and what to do.

Lu Ming pulled over a high-precision map, looked at it, and directly pointed his finger at a point: "Just 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, so it doesn't look like it's valuable.

Zhang Dingshan did not hesitate at all, directly took the communicator, and ordered: "Maneuver to the following coordinates!" ”

Lu Ming also shouted: "Except for the drone pilots, everyone else is wearing equipment, the same equipment as when the encirclement and suppression battle was fought a few days ago!" Wear it now! Pilots get the drone ready! ”

So, while still on top of the helicopter, the guards brought all the equipment with them. The same is true for He Wei.

The helicopter flew at full speed, and in just a few minutes, it came to the open space that Lu Ming pointed to. The helicopter roared down, and the guards jumped out.

"Lu Ming, what should I do next?"

Lu Ming looked at He Wei: "Take people, lurk at the Nanli Laser Research Institute, and then wait for the next order!" Be careful, it's already a gathering place for monsters, so be careful and be careful not to be spotted by them! ”

He Wei was taken aback: "Monster gathering place? What do you mean? Didn't all the monsters be killed? ”

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

"Okay, half an hour at most!"

Zhang Dingshan only realized at this time that the place that Lu Ming had chosen happened to be the closest place suitable for a helicopter to land on the premise of not alarming 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 do you think of? ”

"I thought of a possibility that could explain this event in its entirety within the scientific system."

Lu Ming wiped the sweat from his forehead with a slight tremble, and said in a trembling voice: "This indicates a terrible consequence. What I'm doing now is to scout where the situation is and test that idea.

Captain, the logic is complicated, and I can't explain it in a short time. Now, let's investigate it now, and I hope my speculation is wrong, I hope it's wrong......

Are the drones all ready? All right? Okay, Captain, you go and command the drone formation, and be careful not to alarm them......"

Lu Ming overtook the throne and issued an order directly in place of Zhang Dingshan. Zhang Dingshan's face was full of solemnity, but without the slightest hesitation, he directly passed Lu Ming's request as the commander-in-chief of the scene.

At this most urgent moment, he chose to believe in Lu Ming unreservedly.

Dozens of large multi-rotor drones of silent models roared into the air and quickly flew into the air, and the sound they made quickly became smaller until they were no longer noticeable.

At an altitude of several hundred meters, these drones quickly rushed in the direction of the Nanli Laser Research Institute, and it didn't take long to reach the sky above the research institute. The investigation began.

It's night. The lights of these drones have been turned off, and they are hundreds of meters in the air, making it impossible to see with the naked eye. And these drones are silent models, so you don't have to worry about the sound being heard at this distance.

In the face of the Nanli Laser Research Institute, which is located at the highest point in the surrounding terrain, it is indeed the best means to use drones to carry out reconnaissance from a higher place.

Dozens of drone pilots gathered together, intently maneuvering the drones. The footage they send back also occupies dozens of screens.

The screen in front of Zhang Dingshan and Lu Ming displayed a map with dozens of red dots on the map. Lu Ming knew that each red dot represented a drone. If you want to use the drone's perspective, select it and the image will be displayed on the screen.

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

At night, the Nanli Laser Research Institute, which was photographed with a low-light lens, is clearly visible. So Lu Ming saw that the projector array that he had placed there before to project a picture of the Demon Eye Galaxy on the cliff wall had disappeared at this moment.

After the completion of their mission, these projectors will be placed at the disposal of the Laser Research Institute. Now, I don't know where they got these projectors.

Lu Ming's expression became more and more solemn.

He's thinking hard, thinking fast. At this moment, he was so focused that he didn't even notice the sweat running into his eyes.

Even if Zhang Dingshan had thousands of questions in his heart at the moment, he wisely chose not to bother Lu Ming.

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

He saw that there was nothing strange about the inside of the institute.

The street lights were on as always, and most of the rooms in the institute building were lit off, except for a few rooms that were still on.

After all, it's off-duty at the moment, and it's normal for most rooms to turn off the lights.

There are people walking slowly in the courtyard, some people coming out of the building, and some people entering. It's a little bit smaller, but it's normal.

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

"Can a drone directly capture the interior of a room in a research building?"

"Yes."

The leader of the drone pilot team immediately replied: "As long as you find the right angle, even if the lights are off in the room, the low-light lens can shoot it." Not only that, but if someone inside speaks, the drone can eavesdrop on it. ”

Lu Ming was taken aback.

It's understandable to shoot the picture, eavesdropping on the sound, how is this possible?

There are hundreds of meters between the two, one on the ground and one in the sky.

The person in charge said quickly: "Sound waves cause 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 to the sound that we humans can hear. ”

"Okay, check room by room, and if you detect someone there, report it immediately."

"Yes."

Lu Ming originally thought that there would be results soon, after all, even if he got off work at the moment, there should be many people in the building.

But unexpectedly, after a full ten minutes, no one reported.

"Excluding the windowless rooms inside, there are a total of 136 rooms in the institute building. So far, 89 have been investigated, and no human figures have been filmed, and no voices have been captured. ”

"In the room with the lights on, there are none?"

"Nope."

"Keep investigating."

"Yes."

The drone eventually scouted all 136 rooms. The end result turned out to be that out of so many rooms, only one room was occupied.

Lu Ming immediately recognized this room.

Before, when the projector array was 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 research institute can control the operation of the various instruments and equipment and monitor their status here.

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

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

There are dozens of people, sitting in front of dozens of computers, busy operating. A few others stood there silently, as if they were overseeing the work.

"It's an overheard."

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

Lu Ming heard the sound of crackling and tapping on the keyboard, and there was nothing else.

There was no one in the room with the lights on, and everyone gathered in the control room with the lights off......

What does this mean exactly?

Lu Ming didn't know.

He couldn't be sure if most of the people who were studying at the moment were gathered here just because there was something to do, if the lights in the room weren't turned on just because there was some kind of need, such as optics, after all, it was an optical research institute, and if it wasn't just because there was no need to speak.

Still is...... What's really weird?

Just through remote observation by drones, Lu Ming could not be sure. At the same time, because of some concern, Lu Ming could not send someone to sneak into the research institute to observe on the spot.

He was afraid of alarming the enemy—if the people in the institute were already enemies at the moment.

Time passed bit by bit, and at this moment, it was completely dark. In the distance, the southern city has been lit up and is clearly visible in the dark night sky.

At this moment, I don't know how many people are enjoying a rare leisure time. Lu Ming could even imagine that there must be a surging flow of people on the food street where all kinds of delicacies gather.

Buddies drinking and chatting, couples dating, girlfriends partying, couples with children......

Every store is probably full, and there are even queues.

The shopping malls should be equally crowded, and the roads should be full of traffic......

It is a city with a population of more than 900,000. Although it is not ranked among human civilizations, it is still not small in terms of absolute size.

It carries the lives of hundreds of thousands of people, the lives of hundreds of thousands of people, and the laughter and tears of hundreds of thousands of people.

There was more sweat on Lu Ming's forehead.

Time ticked by. With each second that passes, the hidden danger increases a little.

Zhang Dingshan's brows furrowed slightly, and he looked at Lu Ming: "Let He Wei sneak in directly to investigate?" ”

"No, no." Lu Ming's sweaty head shook slightly: "If the people in the Laser Research Institute have all turned into monsters—or rather, just monsters that still maintain their human appearance, once they are alarmed and flee in all directions, there are too few people in He Wei's place to stop them at all." ”

"Then mobilize the garrison! Surround this institute! The field army has not yet withdrawn! ”

Lu Ming looked at the map.

If you want to complete the encirclement without alarming the internal personnel of the research institute, the encirclement must be greatly expanded. And this is a mountainous area, with complex terrain and lush jungles.

To complete the siege, it is impossible to complete it without a few thousand people. However, the transfer of a few thousand people will take too long......

I'm afraid there's not enough time......

"Let's inform the garrison first, but it should be too late. Be careful, be sure to march covertly, and don't alarm them......"

Zhang Dingshan directly took out the phone and called.

Lu Ming's attention was once again focused on the screen captured by the drone.

He saw that at this moment, in the control room of the Laser Research Institute with the lights off, there was finally other movement at this moment, except for the sound of tapping on the keyboard.

There was a creak, and the door was pushed open. Dongdong's footsteps came, and under the low-light camera shot, a monster with a small pointed head and a hideous bone spur came over with an iron plate.

Monster?

Monster!

Lu Ming was full of excitement.

The next moment, a picture that made him even more frightened appeared.

The monster walked up to a fellow tapping on a keyboard and stood still. The researcher turned, reached out, and pulled out one of his eyeballs and placed it on the plate.

Then he turned around again and began typing on the keyboard, and the monster came behind the next man with an iron plate.
