"Sky?" Lu Weiwei looked at the sky picture in the live broadcast on her mobile phone and said disapprovingly: "If you can't feel the sky, what can you see? Look at the stars? Look at the moon?"
"Lu Weiwei, don't interrupt." Seeing Lu Weiwei talking nonsense, He Junchao couldn't help but said jokingly: "Gu Chen said he can see things, so he must be able to see things. Can your vision compare with Gu Chen? You have no brains.
Not on the same level."
"Is it just your brain that works?" Lu Weiwei glanced at him and said unhappily.
Then he turned to Gu Chen and asked: "Junior brother Gu, you said you can see things. Can you tell anything from these live broadcasts?"
"It's possible." Gu Chen thought for a moment and then said, "The sky is not static. The trajectory of the sun during the day and the stars at night can actually be used as a reference."
In addition, there is also the direction in which the flag is blown by the wind, these are all useful clues.
"So that's it?" After hearing what Gu Chen said, Lu Weiwei felt that there was some truth in it.
But thinking back, Lu Weiwei added: "But based on these alone, it is definitely not possible to judge the location. These are general conditions."
"Of course, these alone are not enough, so now I need to know the direction of the sun during the day and the changing direction of the wind." Gu Chen said.
He Junchao immediately raised his hand and said: "Gu Chen, you don't need to worry about this. There are dog lovers who have recorded the live video and every minute is included for everyone's reference."
"If you don't know the surveillance footage during the day, you can go to the comment blogger's space with the most likes to find it. He has a link to organize the footage."
"Okay." After hearing He Junchao's words, Gu Chen followed He Junchao's suggestion and found the comment with the most likes in the blogger's dynamic comment area of the live broadcast.
Then Gu Chen clicked on the comment blogger's avatar and found the live video link from his feed.
It can be said that dog lovers also work hard to find the flag.
The blogger plans to record every live broadcast and compile a time range.
Dog bloggers are constantly asking for help from netizens in the news and using their own live broadcast videos to look for clues.
Gu Chen sorted things by time and began to use his master-level observation and memory to constantly look for clues for reference.
While accelerating, Gu Chen quickly browsed through the pictures in all time periods.
After squinting and resting for a few seconds, Gu Chen clicked on the live broadcast blogger's specific updates and opened the blogger's recent updates.
After completing a series of operations, Gu Chen started to turn on his computer and search for flight information on the Internet.
Lu Weiwei on the side saw that Gu Chen was starting to become serious, so she quickly moved the small wooden chair and sat next to Gu Chen.
Yuan Shasha also put down her work, stood up directly, and stared at Gu Chen's computer.
Gu Chen opened the notebook, picked up the writing pen, and recorded the specific details.
Lu Weiwei curiously asked Gu Chen: "Junior brother Gu, have you found anything?"
"I have seen the live video footage, and the footage provided by the dog lover is indeed crucial to finding the live broadcast location."
Gu Chen was writing data while answering Lu Weiwei's questions.
Lu Weiwei said again: "So, have you understood the trajectory of the sun and all these things?"
"That's almost it." Gu Chen nodded silently and said, "I said, the picture is not useless, there are still some things that can be referenced."
"The first step is to analyze the trajectory of the sun and see if the sun is visible. If the flagpole is vertical, analyze the angle between the sun and the ground, and combine it with the date to get the latitude."
During the conversation, Gu Chen was already listing the latitude range.
Although Lu Weiwei didn't quite understand it, she felt it was very powerful, so she could only nod her head like a chicken pecking at rice.
Looking at Gu Chen writing the data, Yuan Shasha also asked: "Brother Gu, how do you calculate the longitude?"
"You can also calculate the longitude based on the time it takes for the sun to pass above your head." Gu Chen finished his words and drew a sketch on the draft.
Seeing that Yuan Shasha seemed to understand but not understand, Gu Chen added: "And what about the second one? It is to analyze the wind force and combine it with the direction in which the flag is blown by the wind, and we can speculate."
"If the camera cannot capture the sun, then it should be facing north, and then the flag should be blown to the east by the northwest wind."
Speaking of which, Gu Chen searched for a short video on the Internet. After clicking on it, it happened to be today's weather forecast and weather map.
At this moment, many old and new comrades, including Officer Wang, saw Gu Chen starting to look for the location of the flag, and they all gathered around him out of curiosity.
Gu Chen took advantage of the situation and clicked on the weather map video of the weather forecast and said: "This is the weather report of today's CCTV weather forecast. If you compare the wind direction map, this place should be in the area near Jiangnan City."
"But that alone is not enough." Officer Ding crossed his arms and couldn't help complaining: "Although the area where the northwest wind flows is near Jiangnan City, the area is still too wide and it is difficult to determine the final location."
"That's right." He Junchao also nodded in agreement: "Although you, Gu Chen, can determine the specific location, in the area near Jiangnan City, this statement is too general and it is difficult to be precise."
"Don't worry." Everyone refuted it.
Although he seemed to agree with Gu Chen's words, Gu Chen only narrowed down the search direction, but the one centimeter on the map was still far from the actual distance in reality.
Therefore, the locked area is the area near Jiangnan City, so this area is also extremely vast.
Lu Weiwei scratched the back of her head and couldn't help but say: "Junior Brother Gu's calculations, although they sound much better than searching across the country, are still the same as finding a needle in a haystack."
Glancing at Gu Chen, Lu Weiwei said again: "So Junior Brother Gu, what should we do next?"
"We still need to look for clues." Gu Chen picked up the longitude and latitude range he had just calculated, showed it in front of everyone and said: "Based on the sun's trajectory and wind direction changes, I have roughly determined an area with the highest probability."
"But these alone won't work, so I looked for the live blogger's recent updates."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "I discovered that the person who set up the camera, that is, the live broadcast blogger, had uploaded a photo before the camera was transferred to start the live broadcast."
"And in the lower left corner of the photo, there is a building that looks very familiar. This is a landmark building in Jiangnan City, the Jiangnan TV Tower."
"Let me take a look." Following Gu Chen's guidance, Officer Wang quickly clicked on the live broadcast blogger's dynamic information.
Sure enough, it was discovered that he had taken a dynamic photo shortly after taking away the dog lover's flag.
The live broadcast blogger in the photo is holding a modified flag and showing it off in front of him.
Little did he know that in his background picture, a landmark building was exposed exactly in the lower left corner.
Officer Wang kept zooming in and then smiled with satisfaction: "Yes, what Gu Chen said is absolutely right, that is the Jiangnan TV Tower. I am very familiar with this building. It turns out that it is really in Jiangnan City."
After thinking about it, Officer Wang added, "But just knowing this doesn't mean anything. The place where this guy broadcast is definitely not in Jiangnan City. How can we track it?"
"We can track him with surveillance, but those people said that they can only use public resources, and mobilizing surveillance to find him is obviously a violation of our rules. Even if we find him, it will be useless. How will we explain it then?" Officer Ding said.
Everyone looked at each other and agreed with Lao Ding's opinion.
Gu Chenze added: "It doesn't matter, at least we now know that he is within the scope of Jiangnan City, which has narrowed the scope a lot."
"But the Jiangnan TV Tower is on a hillside and can be seen from many angles, and Jiangnan City is so large, how can it be found?" He Junchao expressed doubts.
I also don’t believe that even if I know that the other party is in Jiangnan City, I can still find this live broadcast blogger without relying on the technical support of the police.
Gu Chen smiled and said: "Don't worry, you can't eat hot tofu in a hurry. Jiangnan City covers a very large area. Although we can use the Jiangnan TV Tower as a reference, live broadcast bloggers can also walk freely within the scope of Jiangnan City."
"But how can we further narrow the scope? It seems to everyone that the clues are interrupted here, but don't forget, this is a 24-hour live camera."
"Although he is facing the sky, who says there are no things in the sky? There are also airplanes in the sky."
"airplane?"
As soon as Gu Chen reminded her, Lu Weiwei suddenly realized: "Yes, some netizens have said that there are planes flying in the sky, but what does this mean?"
"Pah!" Officer Wang snapped his fingers and said, "Flight trajectory."
"Yes, it's the flight path." Gu Chen then operated on the computer again and explained with a smile: "That netizen specially stayed at the live broadcast and successfully caught a plane passing the camera during the live broadcast. This is a line.
Important clues."
"Don't forget, all flight information is publicly available."
"By seeing the time of the plane and checking which planes flew over Jiangnan City at this time point, we can further narrow the scope."
"Yeah, why didn't I think of that?" After hearing Gu Chen's words, He Junchao immediately laughed and said, "I almost forgot about this. The flights over Jiangnan City are actually publicly available for inquiry."
"Pa bang bang..."
Just as He Junchao finished speaking, Gu Chen had already extracted the flight information to the page.
"Found it. Judging from the time when the plane was discovered in the live broadcast and the movements of these planes after they took off normally, these netizens saw a total of three planes flying over Jiangnan City at that time. This is also consistent with the flight information."
During the conversation, Gu Chen printed the Jiangnan City regional map on A4 paper.
He only heard the buzzing of the printer, and Gu Chen said: "Xiao Yuan, help me get the printed things."
"Sigh." Gu Chen reminded after hearing this, Yuan Shasha quickly squeezed through the crowd, took the color drawing from the printer, handed it to Gu Chen and said: "Here, Senior Brother Gu."
Gu Chen took the drawing and began to use a pencil and ruler to sketch on the colored drawing.
With the flight trajectories of these three planes, Gu Chen marked the time nodes when they appeared on the camera.
“Then we connected these three points together, and based on the angle of seeing the aircraft and triangulation, we narrowed the range to the triangle on the color drawing.
"It's very close." Lu Weiwei said with emotion.
Gu Chen glanced at the crowd and said: "Just seeing this is nothing, because from around 5pm to around 7:30pm, I heard many cows braying."
"This shows that the camera must be in this triangle, and there may be a pasture nearby because it is the movement of cattle."
"Let me take a look." According to Gu Chen's reminder, Officer Wang quickly clicked on the time period video according to the time node.
Not long after the playback, Officer Wang heard the braying of the cattle. The sounds came and went, and they seemed to be very close.
"Yes, there are cattle movements nearby."
"Then is there any way to continue to be accurate?" He Junchao asked.
Gu Chen smiled faintly and turned to glance at the night sky outside the window.
Afterwards, Gu Chen stood up and walked to the window with his hands behind his back. He looked at the stars outside the window and couldn't help but smile with satisfaction.
"Junior Brother Gu." Seeing Gu Chen's silence and wanting to know the result, Lu Weiwei quickly reminded him.
"Everyone, look at the position and shape of the Big Dipper in the sky." Gu Chen said.
After hearing what Gu Chen said, everyone immediately walked to the window and began to observe the general direction of the Big Dipper.
"Pick up your mobile phones and take a look at the approximate position of the Big Dipper in the live broadcast." Gu Chen said.
Lu Weiwei was watching the live broadcast, so she picked up her phone and compared the approximate direction of the live broadcast screen with the approximate direction in the sky that she could see with the naked eye.
Lu Weiwei suddenly understood and said hurriedly: "Aim in the northeast direction."
"That's right." Gu Chen directly marked the specific location and the direction of the camera on the color picture.
Then based on the mobile phone map, the specific address was accurately located: "Hexing Ranch."
Knocking on the table, Gu Chen said with a faint smile: "The live broadcast location of the camera is at Hexing Ranch in the eastern suburbs."
"I know this ranch. It is a dairy farm. It mainly provides fresh milk to Jiangnan City. The milk my Xiaobei ordered is from Hexing Ranch." Officer Wang is very familiar with Hexing Ranch.
After being reminded like this by Gu Chen, he suddenly understood.
Lu Weiwei said with a faint smile: "Is the location of the live broadcast really in Hexing Ranch, Jiangnan City? This... this is incredible, right? Then should we go and take back the flag?"
Gu Chen shook his head and said with a faint smile: "We still have to work, how can we go to the eastern suburbs to look for flags?"
"This kind of thing can be left to enthusiastic netizens. Anyway, I estimate that among the nearly one million viewers, there must be citizens of Jiangnan City."
"Yes, we don't need to go out, we are at work after all." Officer Wang also reminded.
Yuan Shasha hurriedly said: "Then what are you waiting for? Brother Gu, please reply to the specific address in the live broadcast room as soon as possible. I really want to know the result."
"Yes, Gu Chen, please reply quickly." He Junchao also couldn't wait any longer.
Seeing how anxious everyone was, Gu Chen replied with a smile: "Okay, I'll reply now."
Gu Chen sat back in front of his computer, while other police officers gathered around Gu Chen.
Everyone held their breath and waited quietly for Gu Chen's operation.
Gu Chen directly edited the address and sent it to the live broadcast room.
And it started to swipe multiple messages at once.
For a moment, the comments in the live broadcast room were flooded with the news that "the live broadcast address is at Hexing Ranch in the eastern suburbs of Jiangnan City."
As soon as someone guessed the specific address, netizens immediately became excited.
"Friend, you said it is in Hexing Ranch in the eastern suburbs of Jiangnan City. Is it reliable?"
"Don't talk nonsense again. You can guess it from just this live broadcast?"
"Yes, brother, how long did it take you to figure it out before you started competing?"
Facing various inquiries, Gu Chen sent another update.
"It only takes 10 minutes to seriously participate in this reasoning challenge from the beginning."
After looking at the specific time, Gu Chen then added: "10 minutes and 5 seconds."
Netizens: “…”
"10 minutes? You guessed it in 10 minutes? Who did you fool, brother?"
"Is this guy bragging? How can he deduce the specific live broadcast location in 10 minutes?"
"That's right, we've been here for so long and don't know how to reason, but you can do it in 10 minutes? Who are you?"
Soon, some netizens clicked on Gu Chen's avatar, checked Gu Chen's specific updates, and immediately returned to the live broadcast room to explain.
"Don't get excited, everyone. I've seen his identity. He seems to be a police officer from the Criminal Investigation Team of Furong Branch, Jiangnan City."
"Jiangnan City Furong Branch? Criminal Investigation Team Police?"
"I'm sorry, even the policeman is participating in the challenge?"
"That must be cheating. The police officer must have located the live broadcast address through internal technical means."
"Then the policeman won't lie, right? Is there any netizen nearby? Can you go and have a look?"
After several netizens raised questions, many netizens followed up with comments.
Mostly it means that if you are nearby, you can go and have a look.
For a while, there was an uproar about whether Gu Chen's statement was correct and whether it violated the rules of the challenge.
However, due to Gu Chen's identity as a police officer from the Criminal Investigation Team of Furong Branch of Jiangnan City, many people still knew about it.
As a result, many netizens began to scroll through the live broadcast room, expressing their willingness to go and look for it.
After Gu Chen read it, he smiled at everyone and said, "Okay, let's go back to work. The result will be clear to us later when these netizens go."
"There's no need to say that. Gu Chen said he was in Hexing Ranch in the eastern suburbs, so it must be there." Officer Wang was quite confident in Gu Chen's reasoning and judgment.
The key is when did Gu Chen fail?
From Officer Wang's understanding of Gu Chen, Gu Chen felt that this reasoning challenge was not too difficult.
Otherwise, it would not have taken just 10 minutes to find the live broadcast location that the entire network was looking for.
It's no wonder that many people in the live broadcast room started to accuse Gu Chen of cheating.
But Gu Chen didn't care about these, the results were the most important.
So continue to work hard.
Although everyone else in the office was persuaded by Gu Chen to return to work, everyone secretly turned on their mobile phones to watch the live broadcast, wondering whether netizens would appear in the live broadcast?
After all, everyone knows very well that it is difficult to find the address in a live broadcast with very few conditions. Is it difficult to do this?
Of course, it is not difficult to say, but it requires you to have a broad enough knowledge and be able to look at the problem from a different perspective.
In everyone's eyes, this is a challenge to find a camera aimed at the sky around the world through courage and wisdom, scientific analysis and high-powered reasoning.
But Gu Chen Te Miao only took 10 minutes.
