Staring at the camera, I thought for a moment and quickly ran up to the third floor.

Through the dim green light of the sign in the corridor, it can be seen that there is a camera facing the window where Sun Shouye had an accident.

A small red dot flashes and flashes, proving that it is still functioning.

I hurried downstairs to the restaurant.

Pushing open the door of the restaurant, everyone else was there except for Hikosu and Tana.

"What's wrong Zhijie? Not full? ”

Yan Liangyi looked at me and said with a smile.

"Ah, how can I be."

I laughed, walked up to Wang Dongru, patted him on the shoulder and said:

"You come to my room, I have something to discuss with you."

Wang Dongru was stunned for a moment, looked at me in surprise, and came back to his senses after a while, and promised:

"Ah, yes, yes."

After that, he stood up and walked out of the restaurant with me.

After entering the room, I closed the door and motioned for Wang Dongru to sit, Wang Dongru patted the footprints on the stool and sat down, which should have been stepped on during the day.

I sat on the edge of the bed, looked at Wang Dongru, and whispered:

"How much do you know about surveillance systems?"

"General monitoring is mainly divided into monitoring, transmission, storage, control, display of these five parts, these five parts are incomplete without any of them, but the transmission system will be different, such as cable, optical fiber, etc., ......"

Wang Dongru replied seriously.

"If I want to check the surveillance footage, do I need an internet signal?"

I interrupted him, I already understood from what he said, he understood these things, there was no need to give me science repeatedly.

Wang Dongru was slightly embarrassed after being interrupted, touched his glasses, and said:

"Oh oh you ask this, this depends on the storage system is used, since the 7G signal is fully popularized, few people will use local data storage, all are Internet upload storage, so that the query of surveillance video content must be achieved through the Internet, but there will be some specific places and companies will use local storage ......"

"What about here?"

I interrupted again.

"Huh?"

Wang Dongru should have understood my intentions, and the doubts on his face disappeared instantly, and he said:

"There are two kinds of public places such as hotels, local and network storage at the same time, after the local storage reaches the upper limit, it will automatically delete and empty part of the earlier content according to the timeline, and the specific amount of deletion is set independently according to different needs, so that there is a double backup when there are any unexpected situations that need to be retrieved and monitored."

Wang Dongru pushed his glasses, and then said:

"In the case of hotels, even if the network is disconnected just after updating the data, there will be more than 15 days of backup locally."

"The computer at the bar in the lobby, can you check it?"

I hurriedly asked.

"Theoretically, there is no problem......"

Wang Dongru was talking, when he suddenly heard Sun Hao's voice in the corridor:

"What are you doing?"

"Ahh

Feng Yuan's voice sounded right at the door.

I put my index finger to my mouth, motioned for Wang Dongru to stop talking, walked quickly to the door, and put my ear on the door.

I listened carefully to the footsteps outside, fading away, then the sound of the door closing, and then turned back and sat down.

Wang Dongru looked at me and asked:

"Are you suspicious of Brother Sun?"

"Sun Shouye's death may not be an accident."

I whispered.

Wang Dongru panicked instantly, bent down, and looked at me nervously:

"Who will have a grudge against him? You...... Are you worried about Brother Zang? ”

"Tomorrow after breakfast, I will take someone to the entrance and exit to build a gate, you will go to the bar to open the computer to check the monitoring, just look at the situation on the third floor from three o'clock to three o'clock this afternoon, remember, you have to check quietly, if someone asks you what you are doing, you make up your own reasons, and tell me quickly if you find any problems."

I'm just a little skeptical, before there is no evidence, I don't want to blatantly check the surveillance, so as not to make people panic, Wang Dongru is a science and engineering nerd, and it is most normal to fiddle with the computer when he has nothing to do.

Wang Dongru nodded thoughtfully and agreed:

"Okay, Brother Zang, then I'll go back first."

He stood up as he spoke.

I opened the door to let him out, looked up at the monitor overhead, the red light was still on, turned around and was about to enter the house, and the third door next to me opened.

Yanxu came out with a medical kit, saw me standing at the door, and said:

"Let's change the dressing."

"Ah, I'll rush first."

I awkwardly agreed, the medicine I just applied this morning, I changed it at noon, and I have to change it again this night, how can I change it so frequently......

But I don't know how to refuse, after all, Yanxu is also out of kindness.

I turned and went inside, rinsed and dried it, and pushed the door open again, looking up at something.

Seeing that I opened the door, Yanxu stretched out his finger and pointed at the camera above, saying:

"There's a ...... for this"

I didn't wait for her to finish, I reached out and pulled her in, closed the door, put my index finger to my mouth and shush.

Walked over to the side of the bed and moved over the stool, motioned for her to sit down, and whispered:

"Camera, yes, I saw it too."

"Brother Sun doesn't look like an accident......"

Yan Su folded the gauze and said:

"He hasn't been bitten, how can he become a living corpse, if he is not bitten, he can become a living corpse when he dies, then it means that we have all been infected, this doesn't seem to make sense."

She said the same as I thought, I also felt something unusual, but I had no clue, and the camera was my only point of breakthrough.

Knock knock

There was a knock on the door.

"Who?"

I asked nervously.

"I, Cao Hua."

Hearing Cao Hua's voice, Yanxu held a cotton ball stained with iodine and looked at me embarrassedly.

"Oh, oh, here."

I promised, if I didn't open the door, I was afraid I wouldn't be able to tell anything.

Opening the door, Cao Hua looked inside and was stunned:

"Why don't I come back later?"

After saying that, he turned around and left.

I grabbed him by the arm and pulled him in, pointing to the medicine box on the table:

"What about changing the dressing?"

"Look at how bad this is."

Cao Hua said and walked over and sat on the edge of the bed.

Hikosu lowered his head and did not speak.

I closed the door, stood next to Yan Xu, waited for the dressing to be changed, looked at Cao Hua and said:

"Brother Cao, what are you looking for me?"

"This ...... Let's wait a minute, and then we'll talk about it after changing the medicine. ”

It seems that Cao Hua has something to say that he doesn't want Yanxu to hear.

After a while, after changing the medicine, Yanxu packed up his things and said:

"I'll go back first, and you guys will rest early."

After speaking, she walked out with the medicine box, and Yan Xu also knew that if she didn't leave, Cao Hua wouldn't say anything.

"Yes, thank you."

I sent Yan Su out of the room, leaned out and saw her enter my room, and then closed the door, turned back and said:

"Say, it's up to the two of us."

"I think that Yanxu also really has a heart for you, and you two are quite compatible, otherwise you will ......"

Cao Hua said with a serious face.

"Let's get down to business, brother, don't make trouble."

I knew he couldn't come for this.

Cao Hua took out his mobile phone from his trouser pocket and clicked it a few times:

"Engineer Zang, please share with us your fence design ......"

The sound of Cao Hua recording me with his mobile phone before the accident in the afternoon came from my mobile phone.

I looked at him in amazement, and he walked over and turned his phone to me.

This afternoon, when I chased Cao Hua to grab his mobile phone, he ran with his mobile phone, and the video was not turned off.

Although the video screen shook repeatedly, it was still visible in the direction of the public toilet, until Sun Shouye landed on the ground, and the video screen stopped shaking, turned low from a high place, and then turned black.

Then the picture in the back was dark, only the voice, it sounded, it should be when Cao Hua put down his mobile phone and put it in his trouser pocket and ran with me to the place where the incident occurred.

"Well, I'm done, what's wrong?"

I didn't see anything abnormal, but Cao Hua came to me and must have found something.

"Look here."

Cao Hua dragged the video progress bar back, and after the plopping sound of Sun Shouye landing, the picture no longer shook, and then Cao Hua clicked to pause and zoom in.

The video is directly above the public toilet, and a slender object appears in the video, a little blurry, and it is difficult to see what it is.

Click play again, this thing spun and disappeared into the video, looking at the movement track, it fell out from top to bottom.

"Guess what this thing is, it looks like it came out of the window where Sun Shouye had an accident, it should have been something thrown out of the window."

Cao Hua looked at me and said.

I suddenly remembered the back of Sun Shouye's bleeding head.

At that time, I seemed to feel a small hole, but I was not sure, and then he turned into a living corpse, and his head was smashed by Sun Hao's crowbar, and then there was no inspection at all, and now the body was wrapped up and thrown under the highway, and it was impossible to verify it at all.

"Could it be that this thing is the murder weapon that killed Sun Shouye? Sun Shouye was already dead before he fell? ”

I looked at Cao Hua and said.

"If it is killed first and then lost, how can Sun Shouye become a living corpse again? The heads are about to be flattened, and the living corpses should be crushed to death. ”

Cao Hua asked me rhetorically.

"I vaguely remember that he had a small hole in the back of his head, and I couldn't see it clearly, so I didn't say it, and the only explanation was that the infection and death occurred almost at the same time."

I couldn't answer Cao Hua's question, so I could only try to analyze it.

"Or, if you are afraid that you won't die, you will come first, and if you fall down, you will die."

Cao Hua's analysis made me shudder.

What kind of festival does this world infested with living corpses have to be, so that people have to kill the survivors who survive together?

"It's all a disaster that I only met later, who would have such a big hatred with him?"

I couldn't figure it out more and more.

"Sun Hao is quite abnormal today, not to mention his remarks during the meal, I didn't expect him to kill the mutated Sun Shouye first, although I haven't known each other for a long time, but it's hard for me to get started."

Cao Hua paused after speaking:

"But he's been working outside with us today, and he definitely doesn't have the conditions to commit the crime."

"Sun Hao doesn't have the conditions to commit the crime, but there are people in the house, but who has the motive to commit the crime?"

My mind was completely messed up.

"In this environment, I just have a new shelter, I should be very happy, no one wants to kill someone, could it be that I know someone's secret secret?"

Cao Hua's words instantly made me think out a thought in my messy mind.

That passport?

Zhang Tuofeng!?

Feng Yuan?

This is the only secret that Sun Shouye knows.

But I have already told Sun Shouye that I will ask Feng Yuan alone, and then Sun Shouye has never been abnormal, and he works normally.

Even if Sun Shouye leaked his mouth to Feng Yuan, Sun Shouye is not the only one who knows about this matter, the passport is still with me, and Feng Yuan has no need to kill Sun Shouye at all......

Gas station?!

"Sun Shouye seems to have started to feel wrong when he came back from the gas station with a wire."

I looked at Cao Hua and said.

When Cao Hua heard this, he put down his phone, nodded after a moment of contemplation, and said:

Sun Shouye went back to get the wire, and it took at least fifteen minutes, what did he see during this time? Or do you know something? ”

"I'll have to go to the gas station to find out, and tomorrow, I'll look for what was thrown out of that video and see what it is, and what's there."

I thought about it for a moment and whispered:

"This matter can't alarm anyone, now one thing can be determined, Sun Shouye's death is not so simple, you must be careful, you talk to Lao Yantou, let him also look at it, you must find out this matter as soon as possible!"

Cao Hua nodded, stood up, and patted me on the shoulder:

"Get some rest, by the way, keep an eye on your guns."

After saying that, he walked out.

After sending Cao Hua out, I locked the door and looked at the tactical vest and fell into deep thought.

Keeping an eye on my gun?

The guns are obviously there.
