Lu Weiwei always seemed to be able to find some tacit understanding with Gu Chen.
After several months of team work, Lu Weiwei has gradually turned into a roundworm in Gu Chen's belly.
For example, when Gu Chen yawns, his next action must be to find water to drink.
For example, when everyone was discussing a problem, Gu Chen frowned and said nothing, which must mean he had some objections.
Another example is that other little policewomen bought food for Gu Chen. If Gu Chen said he didn't have to spend money, then these things... would eventually become Lao Wang's bag.
Knowing Gu Chen too well is sometimes not a good thing...
Being able to keep up with his rhythm but not being able to find the next steps he wants to take is often the biggest headache for Lu Weiwei and Officer Wang.
When Gu Chen found clues, Officer Wang and Lu Weiwei were always slow to catch up with their ideas.
This is a very embarrassing thing for old comrades...
Gu Chen sat in front of his desk, smiled and said, "I can't tell you this right now. Let's talk about it in the evening."
"Mysterious." Lu Weiwei glanced at Gu Chen and walked into the bathroom with a basin.
nine in the morning.
Three people were sitting on a hillside with a drawing board in front of them, creating a sense of ritual like a painter cultivating the beautiful scenery of the mountains and rivers.
This is mainly for show...
It is unreasonable for art students to just enjoy the beautiful scenery without painting.
Besides, several people knew about the situation in Liucun. If they didn't show off, the villagers would easily become suspicious.
But these are actually nothing to the three of them. The most important thing is that no one knows who the mysterious person is now.
Wouldn't it be worse if the identities of the three were exposed?
On the surface, the three of them were sketching seriously, but in fact they were discussing the situation last night.
Gu Chen even told the two of them here one by one his analysis last night and the information he got from the old lady this morning.
People sum up experience from experience...
There were still many discoveries in the ancient temple last night, but unfortunately... everyone did not continue the investigation and adopted the safest method.
Officer Wang casually drew a few strokes on the drawing board and asked: "What happened to the physical condition you said last night?"
Lu Weiwei shook her head: "I wish I knew."
She looked at Gu Chen beside her: "Junior Brother Gu, what do you think?"
"Generally speaking, when the symptoms of people in the village appear, my first reaction is that it may be poisoning."
"Poisoned?"
Lu Weiwei and Officer Wang were stunned.
"That's right." Gu Chen nodded slightly, without stopping the paintbrush in his hand: "Generally, people with symptoms of poisoning will experience nausea, vomiting, dizziness, loss of balance when walking, or even mental disorder."
"Then Lao Wang and I were poisoned last night?" Lu Weiwei looked at Officer Wang suspiciously, and then at Gu Chen: "That's not right, if there is poisonous gas in the ancient temple, then wouldn't it be natural for the mysterious man to stay there by himself?
Digging a grave?"
"That's right." Police Officer Wang also had a rigorous attitude and suddenly became serious: "This mysterious man is hiding in the ancient temple and playing weird sound effects on the speakers for a long time. Aren't they afraid? They won't have any problems.
?”
"So, the possibility is not high." Gu Chen glanced at the beautiful scenery at the bottom of the mountain, then returned to the drawing board and said, "I think it should be some kind of infrasound wave."
"Infrasound wave?" Lu Weiwei was stunned for a moment and asked, "What kind of wave is this?"
Officer Wang sneered twice: "Lu Weiwei, if you don't work hard at ordinary times, you won't be online when chatting at critical times, right?"
"You know what you said." Lu Weiwei rolled her eyes, finally letting Lao Wang catch her pretending to be cool.
"Sound waves with a frequency less than 20 Hz are called infrasound waves. Infrasound waves are not easy to attenuate and are not easily absorbed by water and air."
Officer Wang can only know a rough idea...
During previous training camps, Zhao Guozhi had popularized relevant knowledge to everyone, so Officer Wang still knew something clearly.
Although what Officer Wang said was reasonable, Lu Weiwei didn't believe it. She turned around and asked Gu Chen beside her for confirmation: "Junior Brother Gu, is what he said true?"
"That's right." Gu Chen put the brush back into the pen holder, and then took out another one: "The frequency of sound waves that the human ear can hear is usually between 20 Hz and 20,000 Hz. We consider frequencies below 20 Hz as being inaudible.
The sound waves that arrive are called infrasound waves.”
"But what does this have to do with our physical condition?" Lu Weiwei still didn't understand.
Seeing Gu Chen and Lao Wang's IQs on the line, Lu Weiwei suddenly felt marginalized, as if Lao Wang's IQ had suddenly caught up, but she had not reached the passing mark.
"Senior Sister Lu, let me tell you this." Gu Chen pondered for a few seconds and told her in layman's language: "Infrasound waves of certain frequencies are very similar to the vibration frequency of human organs, so they can easily resonate with human organs. However,
But it is very harmful to the human body, and in severe cases, it can even lead to death."
Startled by what Gu Chen said, Lu Weiwei suddenly frowned and couldn't help but shrink her neck: "According to what you said, the thing that attacked us last night was infrasound waves?"
After thinking for a while, Lu Weiwei retorted: "But how did this thing happen? Is it a natural disaster?"
"It's... it's possible." Officer Wang was about to explain, but suddenly found that he had forgotten everything he had learned at the beginning. He could only say half of the words, and looked at Gu Chen: "You
Let Gu Chen speak."
"Senior Sister Lu is right." Gu Chen was the first to confirm Lu Weiwei's idea: "For example, in nature, there are storms at sea, volcanic eruptions, meteorites falling to the ground, lightning and thunder, whirlpools in the water, tornadoes, and aurora.
, magnetic storms, etc., may all be accompanied by the occurrence of infrasound waves.”
"In human activities, such as nuclear explosions, missile flights, artillery launches, ship navigation, car racing, shaking of high-rise buildings and bridges, and even blowers, mixers, loudspeakers, etc., can produce infrasound waves while making sounds.
"
"Moreover, infrasound waves have a wide source, travel far, have strong penetrating power, and are not easy to attenuate."
"Once it interferes with the normal function of the human nervous system, it will endanger human health, and it will be like the symptoms of poisoning, making people dizzy, nauseated, vomiting, losing their sense of balance and even depressed."
After listening to this, Lu Weiwei suddenly felt very insecure: "That's not right. The natural disasters and man-made activities you mentioned don't seem to exist in this area."
"There is only one possibility." After Gu Chen finished the last few strokes on the drawing board, he threw the brush into the pen holder and said: "That is, someone must have installed an infrasound generator in the ancient temple. This kind of
Things are prohibited and can only be purchased from illegal channels."
Gu Chen stood up and pointed in the direction of the ancient temple: "If we were given some more time yesterday, we might be able to find it."
These clues were calculated by Gu Chen after sorting out all the clues last night and this morning and then using a master's level of logical reasoning.
And using entry-level imagination, the judgment was made after simulating the situation last night.
Officer Wang stopped drawing, flicked the brush, stood up directly, and said indignantly: "As I said, if I can't catch this mysterious man, I, Old Wang, will eat this drawing board."
Lu Weiwei also expressed her position: "If I can't catch the mysterious man, I will go to the desert and count the sand."
The two of them looked at Gu Chen at the same time.
"Junior Brother Gu, please show your attitude." Lu Weiwei said.
Gu Chen scratched his head and hesitated for a few seconds, then said: "If I can't catch the mysterious man, I will go to the Pacific Ocean... to measure the sea?"
Lu Weiwei and Officer Wang laughed out loud...
It was really difficult for Gu Chen to express his position.
Lu Weiwei suddenly looked at the landscape sketch on Gu Chen's drawing board and couldn't help but be surprised: "Junior brother Gu, what are you drawing? Isn't it too good?"
Then, she looked at the ghost talisman drawn by Officer Wang and said, "Old Wang, what is this thing you drew?"
…
…
After dinner, Gu Chen gave the landscape sketch he drew in the morning to the old lady.
In fact, Gu Chen has admired the wandering painter Aguda since he was a child, and he is also quite talented in painting.
Among the three of them, it is not an exaggeration to say that Gu Chen is a true art student, and his works are nothing short of amazing.
In order to dispel the old lady's worries and convince her that the three of them are really here to sketch, the minimum expression is needed.
After dinner, the three of them went out on the pretext of painting night scenes.
But everyone’s destination is still the ancient temple from yesterday.
Since they have a certain understanding of infrasound generators, the three of them are no longer as afraid as before.
After staying there for a short time and being physically strong, the infrasound waves did not cause serious harm to Gu Chen.
So Gu Chen took a large bag of stones and walked into the ancient temple while it was still dark.
Not long after, he came to the only way past the ancient temple and met up with Officer Wang and Lu Weiwei.
"Junior Brother Gu, can those rocks of yours really catch the mysterious man?" Lu Weiwei has always been confused about Gu Chen's operations.
But Gu Chen always had some sense in doing things.
"If the mysterious man comes tonight, there must be a way to find him." Gu Chen said.
A long time passed, and time passed minute by minute...
Eight o'clock.
Nine o'clock.
Ten o'clock.
Eleven o'clock.
The stars in the sky join the Big Dipper...
The three of them were lurking on the only way to the ancient temple. More than four hours had passed, but there was still no movement.
Lu Weiwei was a little impatient and asked Gu Chen: "Will we be affected by infrasound waves here?"
Gu Chen shook his head: "I can't guarantee it, but it's quite a distance from the ancient temple and close to Liu Village, so it should be relatively safe."
"Lu Weiwei, if there was any impact, we wouldn't have stayed here for four hours and stayed in peace." Officer Wang also comforted her.
After all, once bitten by a snake, you will be afraid of straw ropes for ten years. This psychological shadow is understandable.
Another hour passed, until just after early morning, strange screams suddenly came from the direction of the ancient temple.
With the spread of the empty valley, it makes people's hair stand on end, and goosebumps can't help but appear on their bodies.
But this time, compared to yesterday, everyone will be more or less mentally prepared.
"He's here, that mysterious man is here." Gu Chen whispered.
"It looks like it passed from another place." Officer Wang also judged based on experience.
"Since he can stay there and play tricks, the infrasound generator device may have been temporarily turned off by him at this time. It would be safest to arrest him at this time..." Gu Chen took out the bright flashlight and asked Wang
Police officer: "Senior Brother Wang, are you going?"
"Go, of course." Officer Wang felt full of energy now. He wished he could appear in front of the ancient temple immediately and then give the mysterious man a set of military boxing.
According to the plan, Lu Weiwei will provide support from the outside and provide immediate support if the situation changes.
And once the mysterious person wants to escape, there must be a secret observation post to accurately grasp the mysterious person's whereabouts and make sure there is no leakage.
After the division of labor was completed, Gu Chen and Officer Wang headed towards the ancient temple.
After a while, the weird sounds ended...
At this moment, Officer Wang and Gu Chen also touched the periphery of the ancient temple. They lay down in the weeds and observed every move in the ancient temple.
One minute later...
From the side of the dilapidated ancient temple, a man in black wearing a peaked cap poked his head out mysteriously.
After observing for dozens of seconds, he walked out cautiously, put the speaker back into the cellar dug in advance, and removed the charging equipment.
At the same time, he returned to the ancient temple and hesitated for a while before leaving the ancient temple and cautiously heading towards a path.
"The infrasonic device must have been turned on. We have to leave here immediately." Gu Chen reminded.
"Follow him." Officer Wang couldn't wait.
Follow the path the mysterious man left until you reach a narrow passage in the river.
The mysterious man stepped on several towering stones, crossed the river, came to the foot of a willow tree on the side of the road, and pushed out a mountain bike parked there.
Then, riding a bicycle, we headed towards Meishan Town.
"This guy is really cunning." Gu Chen couldn't help but be impressed by the mysterious man's wit: "Riding a bicycle can eliminate noise to the greatest extent. This guy really took great pains to pretend to be a ghost."
"Then what are you waiting for? There is only one road to Meishan Town. If we catch up, we will definitely catch him." Officer Wang now feels that victory is in sight.
Just like Monkey Sun can never escape the palm of Tathagata Buddha...
Just do it.
Back at the Liuqiao on the river outside Liucun, Lu Weiwei had already pushed a motorcycle and rushed to meet her.
The three of them had borrowed this from the landlord's house next door...
Although it's a bit worn and the lights don't work well, the performance is pretty good.
In the afternoon, Officer Wang rode it around Liucun a few times to spend the so-called short running-in period.
So the three of them got on the motorcycle and chased him along the road to Meishan Town.
The mysterious man is very cunning.
In a spacious forest four kilometers away from Liucun, there was a black car parked.
After putting the bicycle in the trunk, the mysterious man drove away, but apparently spotted the motorcycle behind him.
The mysterious man lowered the brim of his hat, accelerated his speed, and soon distanced himself from the motorcycle, disappearing into the darkness.
"This guy is really cunning." The driver, Officer Wang, looked annoyed: "If I had a car, I would definitely catch up with him."
"Senior Brother Wang, don't worry, I've remembered the license plate." Gu Chen's response came from behind him.
"No way? In this blind light, can you see the license plate clearly? Do you think your eyes have 30x digital zoom?"
Even if I beat Officer Wang to death, I wouldn’t believe it...
My eyesight is pretty good, but it is absolutely impossible to see the license plate clearly.
Normal people can have this kind of vision. So far, Officer Wang has never discovered it.
But Gu Chen would not tell him that he had the visual cutting function and his eyes had high-definition pixels.
While Officer Wang was chasing him, Gu Chen had already taken a photo of the license plate information.
The result of the analysis is: 70% probability is ws987, 20% probability is ws997, and 10% probability is ws887.
With this basic judgment, it is not difficult to find a car.
Even though there are many identical license plates across the country, it is not very difficult to find such similar license plates in a Meishan town.
"The license plate is probably ws987. It's a black three-box sedan. Let's look for it according to this standard." Gu Chen said.
Officer Wang said nothing and continued to ride his motorcycle, doing extreme overloading exercises.
Meishan Town has arrived.
On the street, you can occasionally hear a lot of dogs barking, and there are basically no pedestrians on the road.
With street lights, everything becomes brighter.
As soon as Officer Wang reached the intersection, he was attracted by a black car parked in front of a grocery store.
"Lu Weiwei, what's the license plate of that black car?" Officer Wang asked weakly.
"ws...987?" Lu Weiwei replied incredulously: "Isn't this the license plate number that Junior Brother Gu reported just now? Can you really see it clearly?"
Not to mention Lao Wang, even Lu Weiwei was shocked now.
I wonder how good my eyesight is to do this?
However, the focus of Gu Chen's attention was not on this car, but on this store. He casually reminded: "Senior Sister Lu, do you still remember this place?"
Lu Weiwei briefly recalled it for a few seconds, and then said: "This is where we took a taxi. You also bought things in this store. The boss is a one-eyed man."
"That's right." Gu Chen nodded and said, "Since this car is parked here, does it have something to do with the owner of this store?"
"Don't worry about it. If you go over and investigate, you will know clearly. I can also remember the figure of that guy." Officer Wang immediately arranged his clothes and prepared to take Gu Chen and Lu Weiwei to knock on the door.
"Bang bang bang!"
Officer Wang knocked very loudly.
The stray dogs on the roadside were so frightened that they barked at him, but there was still no movement inside.
Officer Wang continued to knock for a minute.
"Who is it?"
Suddenly a light came on on the second floor, and a middle-aged man shouted impatiently: "Who's knocking on the door?"
Officer Wang didn't respond and kept knocking "bang bang bang bang".
Lu Weiwei was panicked and said: "Junior Brother Gu, if we can't find out the problem, we will be considered a nuisance to the people!"
"There is no way. You only have one chance. If you miss it, it may no longer exist." Gu Chen said.
Officer Wang also consoled him: "It's okay, I'll take the responsibility. Just find someone else."
Not long after, the one-eyed boss opened the door and saw the three people staring at him eagerly. He couldn't help but be stunned: "You...who are you? Why are you knocking on my door in the middle of the night?"
Officer Wang pointed at the black car at the door with a cold face and said, "Is this your car?"
"No...that's right, what's wrong?" The one-eyed dragon boss said blankly.
"Did you drive out just now?" Lu Weiwei asked again.
The one-eyed man was obviously frightened and said angrily: "Who are you? What does it have to do with you whether I can drive or not?"
Before he finished speaking, Officer Wang had already hung his People's Police ID card in front of him.
"Police...police?" The one-eyed boss was dumbfounded for a moment.
"Does this car belong to you?" Officer Wang asked.
"Yes...yes." The man may have been a little flustered and spoke incoherently, as if he wanted to make a quibble, but he was in a hurry and couldn't make it right.
"What are you doing out tonight?" Gu Chen asked again.
The man smiled bitterly and said, "I've been sleeping. I don't know what you are talking about."
"You don't have to refute." Gu Chen pointed at the black car and said, "The car is still hot. This car just turned off the engine not long ago."
