When he said this, Lu Siya also fell into deep thought. After pondering for a long time, she had to admit: "It makes sense."

"Also, many Zerg species don't have brains. Even if we can strengthen their intelligence by thickening their nerve cords and covering them with myelin sheaths, they probably won't be able to process information that is too complex."

Meng Chao said, "What I mean is that it is possible to let the Zerg gather together and attack a human building, but let the Zerg process complex image information, identify the subtle differences in different human facial features, find and kill specific

Target, but letting go of people other than the target, I think, is too contrary to their instinct and exceeds the limit of neural processing.

"Of course, the alien beast's 'mastermind' can control the Zerg remotely.

"But monsters can block battlefield information, and so can we. The information link between the 'Mastermind' and the Zerg must be intermittent. It is impossible for it to control the actions of all snakes, insects, rats, and ants in real time just by remote control.

"Also, the strangest thing to me is the fact that the monster captured Dr. Lu Tianxing alive.

"According to the survivors, they were protecting Dr. Lu and a group of time travel experts while blocking the monster's attack while walking through a corridor. At this moment, a large number of monsters suddenly emerged from the elevator shaft and tore the elevator apart.

He opened the door, grabbed Dr. Lu accurately, and without any hesitation, dragged him down the elevator shaft.

"There are two questions here. First, how did the monster know that Dr. Lu and the others would retreat from this route?

"Junlin Hotel does not only have one elevator, but of course there is more than one elevator shaft.

"Each floor has several corridors, as well as emergency stairs and escape routes.

"Dr. Lu and the others have dozens of escape routes to choose from. How could the monster ambush them in advance?

"Okay, ignore this. There were dozens of survivors walking through the corridor at that time. The queue must have been very long. Why should the monster not be early or late? Just when Dr. Lu was passing the elevator entrance, it suddenly tore the elevator door open and opened it again.

Stick him with spider silk and drag him into the elevator shaft?

"You know, when the elevator door is closed, even if the monster and the 'Mastermind' maintain a visual signal connection, it is impossible to see the situation in the corridor. How could they choose their timing so well?"

Lu Siya fell into deep thought. After a moment, an idea flashed: "This problem is very simple. There is a mole among the survivors."

"We originally knew that the alien beasts had penetrated the Blue Home very seriously, and it was in the Blue Home that Lin Chuan and Gao Ye were bewitched by the alien beasts.

"In addition to them, there are also guys who were bewitched by the alien beasts but were not exposed. They have been lurking in the Blue Homeland and appeared as the 'fanatic earth faction'. This is also very possible.

"This 'Travel Technology Seminar' was organized by Blue Home. Information including the meeting time, location, and participants were all transmitted to the alien beast through the inner ghost. Therefore, the alien beast was able to launch a precise surgical operation.

Strike!

"When the Zerg emerged from the ground, the inner ghost stayed close to Dr. Lu Tianxing, using some secret method to guide the monster to its target - what do you think of my speculation?"

"Sister Ya, it's okay!"

Meng Chao's eyes lit up, he patted his thigh and said, "As expected, those who are close to vermillion are red, and those who are close to ink are black. You and I have been working together for so long, and you have finally shown your proud wisdom!"

Lu Siya was stunned for a moment: "What?"

"It's okay. There is a mole in Blue Home, but there are so many suspects that I have been unable to narrow down the scope of suspects. Now it seems that the mole is one of the survivors who followed Dr. Lu Tianxing closely at that time."

Meng Chao changed the topic and said, "But this reasoning only solved the question of 'Dr. Lu Tianxing was captured', but it did not solve the question of the monster being able to accurately target all time travel experts and participants.

“It’s not necessarily true that behind every expert and investor there is a mole, right?”

"this……"

The joy on Lu Siya's face was once again swallowed up by confusion. She paced back and forth, shaking her head and saying, "I don't understand. Could it be that the monster has a way to mark every participant of the 'Time Travel Seminar' in advance?"

Meng Chao's eyes widened and he suddenly jumped up with joy: "Yes, this is it, mark it in advance!"

Lu Siya still didn’t understand: “How to mark it?”

"Think about it, what is the biggest difference between the attendees, the hotel staff, and other guests? Is there something unique to the attendees that other guests and staff don't have?"

Meng Chao looked at Lu Siya expectantly, and after three seconds, he couldn't help but tell the answer, "Badge! They pinned it on their chests, the commemorative medal of the 'New Era 57 Annual Travel Technology Symposium'!"

Lu Siya thought for a while, nodded and said: "Yes, every participant seems to have a badge on their chest."

"Usually when a large meeting is held, the conference organizers will issue some identification signs to allow participants to enter and exit the meeting venue, contact experts and investors attending the meeting, or go to the executive lounge and buffet restaurant for free meals, etc. But generally speaking,

, the identification marks are all name badges, right?”

Meng Chao said, "When I saw the badge on the survivor's chest just now, I felt very strange, because it is rare to see badges used as identification marks.

"You know, Blue Home itself has its own organizational badge. Wouldn't it be better to use the 'name badge + organizational badge' method? Why bother to create a new batch of commemorative badges?

"If it is used as a small souvenir for a conference, we usually order a batch of pens, bookmarks, data memories, etc., and commemorative medals are usually used more when participating in battles or at hero and model commendation ceremonies, right?

“At that time, seeds of doubt arose in my heart.

"It's a pity that undead creatures and snakes, insects, rats and ants came into battle one after another. During the desperate fight, there was no time to think at all. Now that I think about it, it feels weird.

"There must be something wrong with this batch of commemorative medals.

“The reason why we don’t use Blue Home’s own organizational badge is because many people have old organizational badges and it’s hard to use them.

“The reason why we don’t use breastplates is because they are too light and thin and difficult to manipulate.

“The reason why small souvenirs such as pens, bookmarks and data memories are not used is because there is no way to ensure that experts and scholars will carry these small souvenirs with them when they escape.

"Only by handing out tampered commemorative medals during sign-in before the meeting, and even arranging a few staff to help the elderly experts and scholars pin the medals to their chests, can we ensure that all of them are marked with 'marks'

', and these marks will not be thrown away during escape.

"Then, the scope of suspicion of the mole will be greatly reduced.

"The people who created these commemorative medals, the people who were responsible for distributing and helping the participants wear the medals, and among these people, the person who never left Dr. Tianxing's side during the escape - this person, or these people, are the moles!"

Lu Siya looked at Meng Chao in disbelief, her mouth getting longer and bigger.

"No, Sister Ya, I know your admiration is already pouring out, but now is not the time to be stunned. We must confirm this guess."

It is also very simple to confirm whether the medal has been tampered with or not.

Almost all survivors were concentrated in medical camps.

Because the acid and venom contamination in the hotel is too serious, and the new zombie virus and blood-striped flower spores are too mysterious, even if it looks like it is just a slight skin injury, or even unscathed, there is no guarantee that it is not infected with viruses and spores.

spore.

Therefore, people rescued from the building must be isolated for treatment, testing and observation.

Meng Chao and Lu Siya, one is at the pinnacle of the earth realm and the other is a strong man in the heaven realm. They have also been tempered by the blue original mother stone. Their immune mechanisms are impregnable. They are the first people to complete the screening and confirm that they are not infected.

There are also some survivors who have also completed blood and throat sampling and are waiting for test results.

There are many Blue Home members inside.

They all wear "Travel Seminar" medals on their chests.

Meng Chao asked a familiar Blue Home member and borrowed his medal, holding it in his palm.

The first impression is that it is quite heavy to buy. It does not look like the light alloy used in ordinary badges, but rather seems to be made of precious metals such as gold and silver.

The entire badge still uses the blue earth as the main body, but the earth is surrounded by a crystal clear tunnel, connected in the form of a Möbius strip with no beginning or end.

The badge was extremely beautifully made, every detail was meticulously detailed, and Meng Chao couldn't put it down. It's no wonder that all the attendees wore it on their chests.

Meng Chao handed the badge to Lu Siya.

Lu Siya's eyes bloomed with fluorescence, and the light radiated from the eye sockets to the center of the eyebrows and temples.

She activated her "Sensitive Person" talent and stared at the badge for a long time. Then she stretched out her thumb, gently rubbed it, and felt it. After a while, she murmured: "I sensed a very strange... radioactivity? This badge

During the creation, some extremely rare radioactive ores or rare crystal components were mixed in.

"The radioactivity is very weak, it will not harm human health, and it is difficult to be sensed by ordinary extraordinary beings.

"But the perception system of the Zerg is different from that of humans. I'm not sure. Maybe in the perception of the Zerg, a person wearing this kind of badge is as distinct as holding a torch in the dark night."

Meng Chao also took out several reagents from the Reaper tool bag he carried with him.

Place the badge in a metal tray and gently drop a few reagents. When the third tube is dropped, the pink reagent reacts with the badge and a large number of bubbles emerge.

"It's biological material. When these badges were created, they were mixed with biological materials such as monster bone powder."

Meng Chao narrowed his eyes, with a sharp light emitting from his eyes, and said, "Although there is no way to confirm what type of biological material it is, why would an ordinary medal be mixed with radioactive substances and biological materials?
