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

"That's right." Gu Chen nodded and said with a smile: "Any object can play new tricks in front of you, Forensic Doctor Liu, right? You can always find something for me."

"Haha, okay, put the things here first, and I'll give you priority for testing. If it's not urgent..."

"Urgent, very urgent." Gu Chen said without any nonsense, "Why don't you test it for me first? You can also send me the results by email. I must return to Haitang Police Station before dark."

"Okay." Seeing Gu Chen insist, Forensic Doctor Liu naturally knew Gu Chen's habits.

Test first, and the results and reports will be notified via mobile phone.

"Then it will be hard work."

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

As soon as I walked in, I bumped into a middle-aged man in casual 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, why are you walking so recklessly?" The middle-aged man smiled and walked out slowly.

Only then did Gu Chen realize that the man had an excellent appearance, his hair was neatly combed, and he was full of energy. He looked like a big leader.

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

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

"No." Gu Chen shook his head: "I am a police officer from Haitang Police Station of 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 from the Haitang Mining Bureau?"

"That's right." Gu Chen said.

"Then why are you here?" the man asked.

Gu Chen smiled faintly: "While working on the case, there are things that need to be tested."

The man didn't look like he was from the technical department, and as for the forensic doctors from the technical department, Gu Chen was already familiar with the people here because he came here often.

However, the middle-aged man was indeed quite unfamiliar and was not wearing a police uniform, so he couldn't help but ask more: "Do you work in the city bureau?"

The man was stunned for a moment, then said with a smile: "I...I'm not a policeman, I'm an equipment supplier, and I came to the technical department to inspect the equipment."

"Oh, that's it, then you should be busy first." Gu Chen lowered his head and looked at his watch.

I was in a hurry and didn't want to talk to him anymore, so I hurried to the bathroom.

The man turned back and took another look at Gu Chen, smiled and said, "This young man is quite energetic, especially that watch. It feels a bit familiar..."

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

Soon, my mind was spinning.

The surrounding environment quickly became dark.

A bright moon was covered by dark clouds, the breeze blew through the treetops, and the surrounding vegetation began to move.

In the center of the archaeological base, a searchlight supported by a steel frame structure illuminates the surrounding archaeological pits as if they were in daytime.

The scientific expedition team members returned to their residences one after another.

Some are in old houses after cleaning, and some are in temporary tents.

The security personnel on the night shift set up a small tent by the wall outside the pit, and two or three people sat inside and chatted about daily life.

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

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

At this time, the black shadow squatted in the corner, using the weeds as cover, listening carefully to the movements in the house.

Gu Chen lowered his head and looked at his watch. It was already one o'clock in the morning.

In addition to the strange movement of vegetation around, there were also bursts of roaring sounds inside the house.

Seeing that the time was right, the black shadow quietly opened the door and slowly approached a bedside.

Seeing that Professor Li's assistant Xiao Zhang and Professor Peng's assistant Xiao He were sleeping unconsciously, they plugged their nostrils with paper balls, and the shadow opened the gas sealed in the bottle and put it into their nasal cavities.

Time passes minute by minute.

The shadow took back the bottle and quietly exited the room.

"Is there really a gas that makes people sleepy?" Gu Chen couldn't help but think for a few seconds and recalled the knowledge he had.

But I suddenly realized that I had never seen anything like this before.

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

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

In a simulated scenario, this image only exists in your own imagination.

"But why did I not find any broken bottles in Xiao Zhang and Xiao He's room on the first day, but why did I find such broken glass under Master Xiao's bed on the second day?"

With thought, Gu Chen snapped his fingers again.

Soon, the environment was restored again.

It's the same night, and the same black shadow is shuttling back and forth between the old houses in the uninhabited village.

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

The same grass and trees outside, but the snoring in the house kept coming, and the driver, Master Xiao, slept very hard, which shows how hard the work was during the day.

The black shadow lowered his head and smiled slyly, preparing to push the door open quietly and enter.

However, what he didn't expect was that Master Xiao quietly placed a few thick wooden sticks behind the wooden door to hold the door tightly.

If the wooden sticks are not removed from the house, it will be difficult for outsiders to enter.

Since the old houses in uninhabited villages do not have door locks, many people just close the wooden doors lightly and do not lock them when sleeping at night.

The shadow, who had tasted the sweetness of the previous day, could not enter the house at this moment.

But what surprised Heiying was that a piece of broken glass by the window allowed Heiying to find a new flaw.

So the black shadow came to the window and took advantage of the perfect angle to throw the glass bottle in the bag under Master Xiao's bed.

As the piece of glass sealing the gas breaks, the gas begins to spread.

Since the living room and primary and secondary rooms were in dilapidated condition, the room where Master Xiao lived was actually extremely narrow. It was a temporarily renovated room after the kitchen was cleaned, and it could only accommodate one bed.

This is why assistants Xiao Zhang and Xiao He can share a room, but the driver, Master Xiao, only has one room per person.

"Wait a minute." Gu Chen suddenly snapped his fingers, and the screen suddenly stopped.

"That's not right. If it's a glass bottle, how could it break if it's dropped? Is the hardness so low?"

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

Thinking of this, Gu Chen suddenly remembered that he and Qi Tian went to the archaeological site before. When Professor Li took him and Qi Tian down to the pit, Professor Peng was scolding his assistant Xiao He.

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

When he judged that these porcelains were defective, Professor Peng once praised himself highly.

"Yes, the glass piece can be ultra-thin. This is a bottle specially designed to seal 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 any time to think, Gu Chen opened the cubicle door and ran towards Dr. Liu's office again.

"Eh? Gu Chen, why are you back again? I thought you were gone?" Forensic Doctor Liu, who was preparing for the test, was suddenly stunned.

Just now I saw Gu Chen leaving in a hurry. Why did he come back to the office now?

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

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

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

Upon seeing this, Forensic Doctor Liu quickly helped Gu Chen turn on the desk lamp.

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

"Forensic Doctor Liu."

"Um?"

"Have you ever seen such thin glass?" Gu Chen turned to ask him.

Forensic Doctor Liu adjusted his glasses, quickly tightened his upper body, and observed carefully for more than ten seconds before saying: "It really doesn't exist. This is the first time I have seen such thin glass."

"Then this can be considered a real fragile item, right?" Gu Chen asked.

Forensic Doctor Liu nodded: "Yes, such utensils made of glass are rare."

For comparison, Forensic Doctor Liu went to the iron frame in the corner and found a gas-sealed glass bottle.
