Wang Chen told Tu Hongye about the matter, and even mentioned his own speculative judgment of Wu Hao's words before his death, and finally added: "I want to go and find out, since the person suspected of my father is still alive in the satellite video, or I can find him." ”

"As a son of man, this is what should be done, but in principle, you are a public weapon for private use, so the resources I can mobilize cannot be too much and not too obvious, so let's not talk about the two of us, you wait a minute, I will send a squad of soldiers over to search with you, but let's say it first, we can only find it for a day in the name of searching for special creatures, at most until tomorrow night, if there are more, someone really reports it, and I can't explain it."

"Don't, don't, don't, Professor Tu, I understand, really, it's not that exaggerated, I'll just find it myself."

"Come on, Harbin is so big, when are you looking for it? That's it, I'll wait for someone to send over. ”

"No, don't, like you said, I'm a public weapon for private use, I originally went back here to undertake the work assigned by my superiors, and now I came out to find my father privately, it's already too much, and then let the soldiers look for it together, what will it be, otherwise, Professor Tu, Qingru and I will search roughly according to the previous radio branch data, and if there is a finding, I will ask you for help."

"If there is really a group of unidentified people operating privately in the Harbin epidemic area, if the two of you collide with each other head-on, the danger is too great, I think it is better to be careful."

"Actually, I'm also worried that there are too many people, and it's easy to startle snakes."

"Well...... In this way, keep in touch with Yang Xiaohua at any time, Xiaohua's other things will be put on first, except for satellites, I will send a drone over to fully support you. ”

"This ......"

"Come on, it's decided, I feel that you are a lucky general, maybe you can beat rabbits with grass, and you can get a lot of merit."

"Alright then, thank you, Professor Tu."

"Come on, be polite to me, you can see the outside, that's it."

Hanging up the communication, Sheng Qingru chuckled: "The director seems to have chosen a good medicine today, and he is quite crisp when he speaks." ”

"Gotcha...... Hi, I got him on crutch. Wang Chen carefully put away his mother's bones, got up and looked at the sky, and said, "Eat something briefly first, and wait for the specific analysis results of Xiaohua by the way." ”

It's not been long, Wang Chen's self-heating military rations haven't been eaten up, Yang Xiaohua's data collection and preliminary analysis have been transmitted, from the beginning of the outbreak of the epidemic to the recent past, the signal sources shown on the tablet combined with the map of Harbin were quite complicated at the beginning, almost all over the main urban area of Harbin, and then showed a cliff-like decline in quantity, if you say the law, I can't see any rules for the time being, Wang Chen eliminated most of the signal sources, and concentrated the time period on the day when Wang Yefei was taken away, and the picture was suddenly a lot more refreshing. There was a relatively obvious signal trajectory, the source was the location of Wang Chen's house, which continued to the vicinity of Central Avenue and disappeared.

As a landmark street in Harbin, Wang Chen can find it with his eyes closed, he didn't say a word, took Sheng Qingru to start the snowmobile, and galloped away.

From Wang Chen's house to the central street, it takes less than five minutes, the snowmobile is very convenient to stop in the middle of the once busy street, the snow foam blown by the whirlwind is flying wantonly on the century-old street, and the buildings of different styles converge on one street, during the passage, it seems to wander in the corridor of time.

The streets are littered with snow bags of different sizes, which are estimated to be vehicles or zombies buried by the snow, as for those century-old classic European buildings on both sides of the road, such as the Modern Hotel, or Xinhua Bookstore, Hua Meixi Restaurant, even if the first floor is buried by snow, it still exudes infinite artistic charm, even people like Sheng Qingru who don't know anything about art are attracted by the dazzling European style, and can't help but sigh in admiration.

Wang Chen didn't have time to admire these buildings that he was already familiar with, and his whole mind was focused on the traces around him, trying to find any clues on the white snow. After searching for a long time, Wang Chen was disappointed, maybe the snow had covered up the traces, maybe too much time had passed, those people had left Harbin, in short, there was no evidence of human or vehicle activity on the empty and uninhabited streets.

Give up? That's absolutely unwilling.

Wang Chen simply calmed down, leaned on the snowmobile and began to fiddle with the radio information in the tablet, as for Sheng Qingru, after getting Wang Chen's approval and telling him not to run far and pay attention to safety, he began to wander around to see these European-style buildings, not that they were too careless, there were satellites staring overhead, and there were drones transferred by Tu Hongye circling not far away, not to mention that people wanted to sneak attack, and a burst rat appeared in the snow, which could be found at the first time.

Using the retrieval system, Wang Chen expanded the time period of radio communication little by little, and he found that from the beginning of the flood in Harbin to the period when the People's Liberation Army evacuated Changchun, the frequency of radio signal activities in Harbin was quite frequent, and after the army was far away and the satellite was transferred, the time period for the satellite to fly over Harbin every day to collect information was about two to three hours, and during this time, the frequency of radio activities even exceeded the sum of previous days, which shows that there are indeed a group of people in the Harbin epidemic area with a large number of zombies around. On the day when radio communications almost disappeared, just when the temperature in Harbin dropped below freezing, and since then, the radio signal has been almost zero for two or three hours a day during the satellite remote sensing period, and it is likely that these people have evacuated Harbin, is it perhaps not a coincidence? Temperature, perhaps, is a necessary factor in the activities of these people? Didn't those bursting rats also come out when it was cold?

It's useless to get an inference about this, or nothing.

The winter sun in the afternoon shone on Wang Chen's body, just after lunch and because of his anxiety, he felt a little hot, and the tablet computer could not work for a long time at this temperature, Wang Chen simply picked up the computer, untied the thermal insulation mask, breathed a few breaths of cold air, and made himself sober.

As soon as he took off the mask, Wang Chen felt that something seemed wrong, as a native of Harbin, he was quite familiar with the smell of Harbin in winter, or rather, everyone will have an unforgettable impression of the smell in the air of their hometown, but now Wang Chen breathes in the air, there seems to be a little more sweet and sweet smell, you know, the current ambient temperature is minus twenty or thirty degrees, which can cover the smell of such a cold irritating to the human nose, if placed in a zero degree environment, That must be quite strong, Wang Chen deliberately stayed away from the snowmobile, reducing the smell of oil and exhaust brought by the motorcycle, this sweet smell became more and more obvious, he walked along the wind to the upwind, from time to time to blow off the snot blown out by the cold wind, about ten meters, Wang Chen stopped at a vent, this kind of vent is quite common in Harbin, it is part of the underground commercial street ventilation system, because of the cold winter and the summer heat, Harbin's underground commercial street is lined up, it is no exaggeration to say, From one end of the old town to the underground shopping street, you can walk all the way to the other end of the old town without having to go back to the ground for even a single step.

Could it be that after the cold weather, the gang hid underground?
