"Gu Chen, you are in a hurry, and there doesn't seem to be anything special about it. Forensic Doctor Liu took the glass shard that Gu Chen gave him, and couldn't help but nag a few words.

"That's right. Gu Chen nodded and said with a smile: "Any item can play new tricks in front of your Forensic Doctor Liu, can't you? ”

"Haha, that's okay, put things here first, I'll give you priority testing, if you're not in a hurry......"

"Urgent, very urgent. Gu Chen didn't talk nonsense, and said directly: "Either you can help me test first, and send me the results by email, I must return to the Haitang Police Station before dark." ”

"Oh well. Seeing Gu Chen's insistence, Forensic Doctor Liu naturally knew Gu Chen's habits.

First test, results and report, mobile phone notification.

"Then there's work. ”

Bidding farewell to Forensic Doctor Liu, Gu Chen turned the corner and went to the toilet on the floor.

As soon as I entered the door, I met a middle-aged man in civilian clothes.

"I'm sorry. Gu Chen dodged a position, took two steps back, and gave up the passage to the middle-aged man.

"Young man, how do you walk recklessly?" the middle-aged man smiled and walked out slowly.

Only then did Gu Chen realize that the man had excellent appearance, his hairstyle was meticulously combed, and he was very energetic, and he looked like a big leader.

"I'm sorry, but I'm on a mission, so I'm walking in a hurry and accidentally bumping into you. Gu Chen also spoke politely.

The man smiled, "Are you a forensic doctor?"

"It's not. Gu Chen shook his head: "I am a police officer from the Haitang Police Station of the Furong Branch." ”

"Furong Branch?Haitang Police Station?" The man looked up at the ceiling, hesitated for a few seconds, and then said, "Is it the police station over there of the Haitang Mining Bureau?"

"That's right. Gu Chen said.

"Then why did you get here?" the man asked.

Gu Chen smiled faintly: "Handling the case, there is something that needs to be tested." ”

Looking at the man, he doesn't look like he is from the technical department, not to mention the forensic doctors in the technical department, Gu Chen has long been familiar with the people here because he often comes here.

However, the middle-aged man was really unfamiliar and did not wear a police uniform, so he couldn't help but ask: "You work in the city bureau?"

The man was stunned for a moment, and said with a smile: "I...... I'm not a police officer, I'm an equipment supplier, and I've come to the technical department to overhaul the equipment. ”

"Oh, I see, then you get busy. Gu Chen looked down at his watch.

I was in a hurry, and I didn't want to talk to him more, so I hurriedly ran to the bathroom.

The man glanced back at Gu Chen, smiled and said, "This young man is very energetic, especially that watch, how does it feel a little familiar......

Gu Chen came to the bathroom, washed his face by the sink, casually found a cubicle and walked in, locked the door, and quickly closed his eyes.

Soon, the world swirled in my mind.

The surroundings quickly became dark.

Babble!

A bright moon was obscured by dark clouds, and a gentle breeze blew through the treetops, and the surrounding grass and trees began to move.

In the center of the archaeological base, a searchlight supported by a steel-framed structure illuminates the surrounding archaeological pits as if it were daylight.

The members of the expedition returned to their residences one after another.

Some are in old houses that have been cleaned up, and some are in makeshift tents.

The security personnel on night duty set up a small tent by the fence on the periphery of the pit, and two or three people sat in it and chatted about family life.

At this time, a black shadow frequently shuttled between the abandoned old houses in the uninhabited village.

Gu Chen lifted God's perspective and positioned himself next to the black shadow.

At this time, the black shadow crouched in the corner of the wall, using the weeds as a cover, listening carefully to the movement in the house.

Gu Chen looked down at his watch, it was already one o'clock in the morning.

In addition to the movement of grass and trees around, there are also sounds in the house.

Seeing that the time was ripe, the black shadow quietly pushed open the door and slowly approached the head of a bed.

Seeing that Professor Li's assistant Xiao Zhang and Professor Peng's assistant Xiao He were asleep unconscious at the moment, they plugged their nostrils with paper balls, and the black shadow opened the gas sealed in the bottle and put it into the noses of the two of them.

Minutes and seconds passed.

The dark shadow withdrew the bottle and quietly exited the room.

"Is there really a drowsy gas?" Gu Chen couldn't help but think for a few seconds, recalling the knowledge he had mastered.

But I suddenly found that I really hadn't seen it in this regard.

At this moment, the black shadow retreated into the grass, and its body gradually became transparent, and finally dissipated from sight.

"Could it be that Xiao Zhang and Xiao He were unconscious because they inhaled a special gas?" Gu Chen clasped his hands to his chest and frowned in thought.

In a simulated scenario, this kind of image only exists in one's own imagination.

"But why didn't I find any broken bottles in Xiao Zhang and Xiao He's room on the first day, but under Master Xiao's bed on the second day, I found this kind of broken glass?"

With thought, Gu Chen snapped his fingers again.

Soon, the environment was restored again.

It was the same night, and the same dark shadow was shuttling back and forth between the old houses in the uninhabited village.

At this moment, he came to the door of another old house and crouched in the corner to listen carefully.

It is also the grass and trees outside, and the snoring in the house comes and goes, and the driver Master Xiao sleeps very hard, which shows how hard the work is during the day.

The black shadow bowed his head and smirked, ready to quietly push the door in.

However, to his surprise, Master Xiao quietly placed a few thick wooden sticks behind the wooden door and pushed the door to death.

If you don't remove the sticks from the house, it's hard for outsiders to get in.

Since there are no door locks in the old houses in uninhabited villages, many people only gently close the wooden doors when they sleep at night, and they do not lock them.

Having tasted the dark shadow of the sweetness of the previous day, he could not enter the house at the moment.

But to the surprise of the black shadow, a piece of broken glass by the window allowed the black shadow to find a new flaw.

So the black shadow came to the window, and used the excellent angle to throw the glass bottle in the bag under Master Xiao's bed.

As the glass sheet of the sealed gas shatters, the gas begins to spread.

Because the living room and the main and secondary rooms are damaged, in fact, the room where Master Xiao lives is extremely cramped, and it is a temporarily modified room after the kitchen is cleaned up, and in fact, only one bed can be placed.

This is also why, the assistant Xiao Zhang and Xiao He can have a room, but the driver Master Xiao is only one person in one room.

"Wait. Gu Chen suddenly snapped his fingers, and the picture suddenly froze.

"No, if it's a glass bottle, how can it be broken when it falls? Is there such a low hardness?"

Gu Chen thought that when he was at the scene and picked up the fragments with tweezers, the fragments seemed to be very thin, completely different from the thickness of ordinary glass.

Thinking of this, Gu Chen suddenly remembered that when he went to the archaeological site with Qi Tian before, when Professor Li took himself and Qi Tian to the pit, Professor Peng was reprimanding his assistant Xiao He.

At that time, I once picked up Professor Peng's gloves and observed those broken porcelain.

At that time, when he judged that these porcelains were defective, Professor Peng once highly praised himself.

"That's right, the glass can be the ultra-thin kind, and that's the bottle that seals the gas. ”

Thinking of this, Gu Chen suddenly snapped his fingers.

Soon, the world was spinning again.

Gu Chen opened his eyes, and everything returned to reality.

Without thinking too much, Gu Chen opened the door of the cubicle and ran towards Forensic Doctor Liu's office again.

"Huh, Gu Chen, why are you back again? I thought you were gone?" Forensic Doctor Liu, who was about to test, was also suddenly stunned.

Just now, I saw Gu Chenhuo leaving in a hurry, how could he return to the office after this effort?

"Forensic Doctor Liu, are those fragments still there?" Gu Chen hurriedly asked.

"Yes, you wait. Forensic Doctor Liu took out the evidence collection bag that Gu Chen handed over to him from a plastic frame, and asked rhetorically, "What? Do you want to take it back again?"

Gu Chen didn't have time to explain, but casually picked up a pair of white gloves on the table and put them on his hands, then took out a long pair of tweezers, and sandwiched the glass fragments in the evidence bag under a table lamp on the table.

Seeing this, Forensic Doctor Liu hurriedly helped Gu Chen turn on the lamp.

The bright light shone on the glass, Gu Chen's eyes were bright, and he repeatedly checked all angles of the glass.

"Forensic Doctor Liu. ”

"Huh?"

"Have you ever seen such a thin glass?" Gu Chen turned his head and asked him.

Forensic Doctor Liu helped his glasses, tightened his upper body, and carefully observed it for more than ten seconds before saying, "It's really not, it's the first time I've seen such a thin glass." ”

"Then this can be regarded as a real fragile product, right?" Gu Chen asked.

Forensic Doctor Liu nodded: "Yes, generally this kind of utensils made of glass are rare. ”

In order to make a comparison, Forensic Doctor Liu also went to the iron frame in the corner of the wall and found a glass bottle that sealed the gas.

"Look for yourself, how thick is an ordinary glass bottle, and what is the thickness of the glass piece you found for me?"

"At least three times the difference in thickness?" After Gu Chen confirmed, he turned his head to look at Forensic Doctor Liu.

"Haha, that's right, you're really far behind. ”

"But the glass bottle I found you, some of the fragments are frosted, judging from the shape, this should be the frosted of the bottle mouth, used to seal the gas, right?" Gu Chen turned his head and asked again.

This made Forensic Doctor Liu stop, and he quickly took the tweezers in Gu Chen's hand, picked up one of the frosted glasses, and placed it under the lamp to check it for himself.

"Hey, really, this one is really used to seal gas. "Forensic doctor Liu said it was amazing.

Gu Chen smiled and said, "Then there is Forensic Doctor Lao Liu, help me use these glass fragments to restore the appearance of the utensils." ”

"It's hard. Forensic doctor Liu said.

"I just need a rough outline, as long as I can prove that this is a glass bottle with a frosted mouth, which can be used to seal gases. ”

Gu Chen's request was also very simple.

He now urgently needs to restore these clues, especially the items at the scene, so that he can provide himself with sufficient physical evidence.

Forensic Doctor Liu pondered for a few seconds, then turned to look at his assistant and said, "He may be able to." ”

"Whoever it is, it's best to help me restore it today. Gu Chen looked down at his watch and said in surprise: "Ah, after so much delay, no, I have to go back quickly." ”

"Okay, if the restoration is successful, I will notify you as soon as possible. ”

"Thank you, Forensic Doctor Liu. ”

After a few brief greetings between the two, Gu Chen left quickly.

......

......

5 p.m.

Haitang Police Station

Gu Chen, Qi Tian and Officer Tan, who had brought their daily necessities, were ready to go to the uninhabited village for dinner, and then stay in the uninhabited village for one night, ready to start investigating the strange events in the archaeological base.

Officer Tan sat in the co-pilot boredly, stretched his body, adjusted the seat angle to the maximum, felt the relaxation of his neck, and rehashed the old words: "Do you really think that the strange incident in this uninhabited village archaeological base is someone deliberately pretending to be a ghost?"

"Other than that, is there any other possibility?" Gu Chen said lightly, not like a joke at all.

In fact, he really doesn't like to joke.

At present, there are three people who need to be protected, so according to the plan, the three professors will be protected by three people, and anyone who has trouble must be closely monitored.

Officer Tan didn't have to argue, and he didn't want to argue, so he squinted, looked at the scenery outside the window, and hummed a small tune from time to time.

The scenery outside the window is very beautiful, and the scenery on the periphery of the uninhabited village is even more beautiful, and several vehicles transporting materials also followed the police car and arrived at the uninhabited village archaeological base together.

When everyone first arrived, it was just in time for the archaeological team to have dinner, so they got off the bus to enjoy dinner together.

The canteen master of the archaeological team was skilled, and Qi Tian and Officer Tan were full of praise.

But Gu Chen's mind is not eating, if that mysterious person still wants to act again tonight, maybe he can catch it, right?

As soon as he thought about it, Professor Peng took some fried chestnuts and sent them to Gu Chen, Qi Tian and Officer Tan and said, "Come on." ”

"It smells so good. ”

Gu Chen took two, while Qi Tian and Officer Tan each grabbed one handful.

"Professor Peng, are you going to the city or the province today?" Gu Chen asked Professor Peng while eating chestnuts.

"I'm going to a meeting in the province. Professor Peng sat next to Gu Chen and explained: "Early in the morning, I went to the city with the truck driver of the scientific expedition team to take the high-speed train to prepare for the next step of the base. ”

"You just came back?" Gu Chen asked again.

"yes, what's wrong?" Professor Peng asked.

Gu Chen shook his head and continued to eat chestnuts.

Professor Peng's feeling gave Gu Chen a cold attitude, which was true for people and things.

But the heart doesn't feel bad.

He can reprimand his apprentices in front of everyone, but he can share delicious food with everyone.

What does this mean?

Nothing can be said.

Gu Chen felt that he would not change his suspicion of Professor Peng just because he was bought a few chestnuts.

The real initiator has not been found, Professor Li, Professor Wang and Professor Peng, everyone has doubts.

At this time, Professor Li also came over with a bag of snacks and said, "Officer Gu, Officer Qi, Officer Tan, I went to the supermarket in the town to buy something for you, and you can take it and eat it." ”

"What's so embarrassing about that? Look at how many things you buy. Officer Tan was the first to stand up, his eyes glancing into the shopping bag, and he said, "What are they?"

"Peanuts, melon seeds, eight-treasure porridge, beer, drinks, mineral water, are some daily snacks, you must be working hard to keep vigil here at night, so you have to take these things no matter what, and I can rest assured that you are here." ”

Professor Li is extremely attentive.

Professor Peng had just brought chestnuts on his front foot, and Professor Li had brought snacks on his hind feet.

Gu Chen even felt that he was not here to work, but to have a snack.

"Take the mineral water, and give the rest to everyone. Gu Chen also took out a bottle of mineral water and said.

Several people are blaming back and forth......

A few minutes later, a taxi gradually approached in the direction of the uninhabited village.

Professor Peng took a look and said with a smile: "It seems that Professor Wang is back, and he probably has purchased a lot of things, right?"

"After a whole day, it was time for dinner. Professor Li also smiled, took the snack in his hand and walked over.

After Gu Chen finished dinner, he twisted the cap of the bottle and took a sip of mineral water, and walked over with Professor Li.

The target of my "stalking" tonight is Professor Wang, so I have to say hello to him in advance.

The driver was making a ticket, and Professor Li walked directly to the back door and helped Professor Wang open the door, but he was surprised by the scene in front of him.

"Wang ...... Professor Wang, Professor Wang, what's wrong with you?"

"What's going on?" Gu Chen also hurriedly stepped forward.

At this moment, Professor Wang was lying in the back seat and falling asleep, and the whole person seemed to be unconscious.

Gu Chen rushed forward and pinched Professor Wang's person, but it was still ineffective.

Qi Tian and Officer Tan, who found that the situation was wrong, also quickly put down what they were doing and ran to the taxi quickly.

"Gu Chen, what's going on?" Qi Tian asked.

"It seems to be in a coma. Gu Chen said.

Professor Li took a few steps back, his face turned blue and said, "This ...... Isn't this the same symptom as the three of them......? How so?"

Gu Chen hurriedly detoured to the front row, opened the taxi driver's door, and said, "What's the matter with the person in the back, what did you do to him?"

"Wronged...... Wronged, how do I know what is going on with him?" The driver was also confused, and when he saw that the people in the back row were unconscious, he also jumped at that time.

Qi Tian also said: "He is your car, and you drive all the way to the uninhabited village, don't you notice it at all?"

"I ...... I really don't know what's going on? I'm just a taxi driver, how do I know what's going on with him? I don't know!"

"...... you" Qi Tian wanted to ask again, but was directly stopped by Gu Chen.

"Senior Brother Qi, let me come. Gu Chen said.

Qi Tian waved his hand, and stood aside with his crossed waist in anger, feeling that this thing was really evil.

"I'll ask you. Gu Chen adjusted his state and asked him lightly, "When was the last time you communicated with the passengers in the back seat?"

"This ......" the driver thought for a while and said: "It seems that when entering the fork in Haitang Town, because the intersection is building a road, there are many forks in the road that people can't tell the difference, so I asked the road, and he told me where to go." ”

"What about later?

"Yes. The driver said with great certainty: "Later, I kept listening to the radio and didn't pay attention to the situation in the back row, and besides, the passengers in the back didn't communicate with me much, so I didn't pay attention." ”

"After coming to Haitang Town, did you stop halfway?Did you encounter any suspicious people or vehicles?" Gu Chen continued to ask him.

The taxi driver suddenly fell into deep thought......

This question was indeed a bit unexpected, but after a few seconds of short recollection, the driver nodded and said, "Yes." ”
