Yujing Headquarters Building.

Recently, I've been working overtime for several days in a row, and even the body of the stranger feels a little overwhelmed.

Tian Qing, as a recruit who is not so new, has already brought out several batches of newcomers, and now he has brought a few more.

Lin Weimin and his apprentice walked in from outside, and Tian Qing hurriedly asked, "Brother Lin, is there a problem over there that I just reported?" ”

Lin Weimin shook his head, "No, I didn't tell the adults about a child's awakening ability, it has been confirmed, and the six teams ran for nothing." ”

"Damn!"

They thought they had found traces of the undead, but it turned out to be an oolong.

"Fuck, how are these undead hiding?"

He couldn't help but swear, because these days, he really didn't find any clues, even if he was tired, the key was that there was no gain, his body was tired, and his heart was tired.

Tomorrow is a long holiday.

Some time ago, a large number of reconnaissance activities were discovered and reported in various places, what if the undead spies took advantage of the holiday to engage in a few big incidents, or when they were on full alert?

Time seems to be counting down, and the closer they get to the holidays, the heavier the uneasiness in their hearts.

Yang Chengrong is in a meeting at the moment, with some experts who study biological structures and other experts, and the topic of the meeting is how to find those undead spies out of the vast sea of people.

"At the moment, we have received information that the aura value is high enough to be able to detect the faint aura of the undead, and we have made a portable detection instrument, but the premise is to use it close enough."

This was the last time Qiao Ji sent them a message, and at the moment, they had no more progress.

The instrument is similar to the tool used for security checks, it is a black board that can be held with one hand, and it can be swept at people.

"However, we have only just made a prototype, and it will take some time for mass production."

Another expert spoke: "We have already come up with a way to deal with the self-detonation measures on the undead, the same way of thinking, to guide, preferably to the sky." ”

The way Qiao Ji dealt with it last time gave them an obvious idea, that is, it was difficult to cover the power of self-explosion by force.

But to guide the heavens and let it vent out, it is much simpler, and even only Xuan-level high-level telekinesis is required to be able to do it with the assistance of special equipment.

"We have people process special equipment containing the power of sublimation, which can guide the power of the undead to self-destruct, if this set of equipment is used by a Xuan-level high-level telekinetic ability, after our calculations, even if it is more than three times the power of the last self-explosion, it can be guided."

"How many sets of equipment have been made now?"

"For the time being, there are only 30 sets, and this is thanks to the material support provided by Warehouse 6."

Thirty sets, barely enough, and there is a way to deal with it after finding the undead spy.

Of course, this is just an emergency solution, in fact, in order to deal with the undead spy, there are now a lot of ground-level supernatural people from all over the country, and once the undead spy is found, the ground-level supernatural will be given priority.

Unless something special happens, the Xuan-level Abilities will be allowed to use special equipment to make an emergency.

"Is there a way to lock down the location of the undead spy? It's almost time for a long vacation. ”

Silent.

The experts at the meeting were silent, this issue is the most urgent, but it is also the most difficult.

"Ahem, I'll say a few words." A middle-aged man spoke.

"Professor Song, please speak."

"This undead, according to our only specimen, they are spiritual bodies that occupy the physical body, and the physical body is still active, which makes them basically the same as us in appearance and living habits."

That driver was not transformed by the undead spy with some kind of change-like ability, but the spirit body of the undead occupied this body, replaced the other party's life, and still maintained the other party's life trajectory.

This is the reason why he appeared on the construction site, because the undead spy did not want to change the original life trajectory of his body, which aroused suspicion, although this had a certain impact on his inquiry, but it was not big.

"Professor Song, we all know this." Yang Chengrong reminded that his spirit is not very good, mainly because he has not made much progress these days, and he feels that a big stone is pressed in his heart.

Even if you lie on the table and squint for a while, you feel like your heart is being pinched by someone.

The difficulties are there, and they are great, and now the undead spies are so well hidden that they can't find them at all, and the other party is usually the same as ordinary people.

Unless people can be pulled for testing, then the results should be obvious, but this is completely impossible, with such a large population in China, can they all be tested?

It's almost as good as being able to narrow it down and down again.

Professor Song smiled and continued, "We found the residual food in the stomach of the only sample, which is very ordinary vegetables and meat, which shows that his diet is the same as ours. ”

"We all eat the same food, so there's no way to investigate the food we buy." Yang Chengrong said quickly.

The undead in the last immortal painting incident would buy pigs to eat meat and drink blood, which can be regarded as an obvious feature, and can be investigated according to this point.

But this time, the undead spy even eats the same as a human, how to check?

Professor Song pushed his glasses, reflecting the light of wisdom, "The food is the same, but they pull it differently." ”

"Huh?"

Pull differently?

"We tested the only sample in all directions and determined that he was almost indistinguishable from a normal person."

Almost.

Everyone knows that this must be a turning point.

"But the problem is with their excrement." Professor Song said, "Actually, we didn't notice this at first, until you gave me permission, I couldn't find my way to look through all the news about the undead, and then I saw a paper on black fog, and at this time, I found a breakthrough. ”

"The black fog is energy, matter, or spiritual power, it is a weakened version of the sublimation power, which is the main idea of that paper."

"So I'm thinking, if the undead carries the black mist, then after he occupies the human body, will the black mist enter the body's metabolism?"

"The answer is yes, the black mist entered the human circulation, although it was so small that it was difficult to detect, but it was real, and we detected it."

Speaking of which, everyone probably understands Professor Song's idea of solving the problem.

"Since we can detect trace amounts of black fog in the excrement of the undead spy, I went to ask the author of the paper, Comrade Qiao Yao from Warehouse No. 6, to help me design a method that can detect black fog, because we have not detected black fog before."

"Now, Warehouse No. 6 has sent people to collect samples from various sewers in Quanyujing, as long as it is tested in sections, which section has problems and which section is not, you can lock the approximate range of activities of the undead spy."

Everyone nodded.

It's still good technology, and you can use this method to find traces of undead spies.

"There are also quantum computers in Warehouse No. 6, which can assist in big data analysis, and before I came to the meeting, they were still testing samples from various sewers in Yujing, saying that they would give me the results within fifteen minutes."

Professor Song looked at his watch, "It's been twenty minutes now. ”

Yang Chengrong hurriedly came to the computer, "Cangjie, has the location of the undead spy been locked?" ”

The police system has also been using the new version of the Cangjie system to assist, the efficiency is fast, can save a lot of time, just two days has received unanimous praise from everyone.

If it weren't for the fact that they have been overwhelmed by the undead spy in the past few days, and everyone is working overtime, they should have reduced their workload because of the new version of the Cangjie system.

"The specific location is not locked, but through a large amount of data comparison, the range of activities of the undead spy has been obtained, but its range of activity is large and the population is large, so it is recommended to make careful arrangements before arresting."

On the projection screen, in the map, some places are marked in red, and the new version of the Cangjie system has helped them narrow down the scope to the community.

Yang Chengrong nodded, smiling for the first time in these days.

"I've finally found you bastards."

(At a certain time, in the sewers, the Black Shadow Soldiers were collecting water samples with expressionless faces.) ）
