I stared out the window at the black helmet.

Rider? Survivor?

Boom!

The other hand also slammed on the windshield, this hand was not wearing gloves, and I was stunned to see the hand that was long gone, and half of the index finger had been broken.

Living corpses!

I quickly took out my pistol and was just about to get out of the car to deal with him, looking at the helmet on his head, I quickly stopped opening the door in my hand.

It is possible to shoot only from the front, and the transparent mask of the helmet can still be pierced.

It's impossible to determine how strong the helmet is, but if it can block a bullet and can't kill a few shots, you can only fight hand-to-hand.

In hand-to-hand combat, if there is a slight difference, it will be more than lucky.

Be steady.

A quick glance at the console, I found the button with the window symbol printed on it, and pressed it.

The co-pilot's window glass slowly fell, and a gap of about two centimeters appeared in an instant, and I quickly pressed the button again, and the window stopped falling.

The living corpse was attracted by the sound of falling from the car window, moved to the side of the car, and desperately stretched his fingers through the crack in the window, seeing that the flesh on his hands had been scraped by the car window, and even Sen Sen's white bones had been exposed in some places, and he was still stretching in hard, and he could vaguely hear the roar coming from the helmet.

I raised my gun and aimed at the helmet that was bobbing from side to side, put my finger on the trigger, looking for the best angle to shoot, and finally caught a frontal moment.

Decisively pulled the trigger, and the living corpse fell to the ground in response, which was considered safe.

Its hand was still stuck in the window, and I put the glass down, and it fell out and fell to the ground with a thud.

Open the door and get out of the car, drag the living corpse to the side of the road, and drop it down the slope.

Watching it slowly roll down the slope, I suddenly remembered the origin of this living corpse!

The motorcycle that was hit by a taxi when I first went to the city!

That place is at least twenty kilometers from here! Not counting this U-shaped turn, the vertical distance has to be five or six kilometers!

What attracted it to this place?

Where would he be hiding during the day? Could it be that it is a slope on both sides of the highway? The sound of driving brought it up?

Looking around, I still couldn't find a reasonable reason, thinking that there were many things to do to go back, I didn't stop any longer, turned around and got on the bus, and continued to drive to the service station.

It didn't take long to get to the service area, and when I stopped the car, I took out a cloth bag from the trunk, loaded the vegetables into it, carried the gas, turned over the pile, and walked into the yard.

Feng Yuan and Sun Hao, who were in charge of the guards, saw me, but I was not in a hurry to confront Feng Yuan, said hello to them with a smile, and walked straight to the restaurant.

Walking into the restaurant, I sent my things into the kitchen and beckoned Wang Dongru to come with me and help move them again.

When he came to the car again, Cao Hua didn't know where he came from, he was already standing next to the car, and he didn't see him in the restaurant just now, so he probably walked around.

Feng Yuan also ran over with a snort, dressed in a rough style and said:

"Just watch Sun Hao over there, I'll help move things."

As he spoke, he opened the car door, handed out a few bags of clothes, and was suddenly stunned.

I guess I saw the newspaper I threw under the passenger seat.

I stood behind him, pretending not to see his reaction, and continued to play dumb, saying:

"There shouldn't be much in it, just to get some clothes for Li Min and them, this time I simply got all the numbers, this time only lesbians."

Feng Yuan continued to hand out the clothes.

When I took it, I could clearly feel his hands shaking.

"Okay Feng Yuan, you go back, I guess Sun Hao himself is even more bored there."

Just as he was taking the clothes, I reconfirmed the birthmark behind his ear.

Seriously, at that moment I wanted to shoot him directly.

But that's too cheap for him.

"Ah, okay."

Feng Yuan's face no longer had the calmness he had before.

Cao Hua took the clothes from Feng Yuan's hand and followed, and the three of them walked towards the restaurant.

Entered the dining room and put the clothes on the table:

"Ladies, the clothes are here, all the sizes are available, you can divide them."

Hikosu looked at me, didn't speak, and didn't come.

Sun Kexin pulled Jin Lan and walked over happily, but Yan Xu was still sitting there and didn't move.

"Yanxu, there are yours too." I beckoned her over.

"I have clothes to wear, Sister Min, you two go over and pick them out."

Yan Su still didn't come over, but asked Li Min to come over.

I looked at Yan Xu inexplicably and embarrassed for a while, and muttered in my heart:

It's not enough......

Li Min quietly pulled my arm and whispered:

"I'll just help her hold it, don't ask her."

I quickly nodded.

Cao Hua sat in front of the window, smirking at me all the time, I walked over in confusion and asked in a low voice:

"What are you smiling at?"

As he spoke, he took the water cup, poured some water, and dried it in one gulp.

"It's good to laugh at your woman."

No matter how I heard Cao Hua, it didn't look like he was praising me, and I didn't bother to pay attention to this, waved my hand, leaned into his ear and whispered:

"Sun Shouye was killed by Feng Yuan, and he didn't run away."

"Are you sure? What's in the newspaper? ”

Cao Hua looked at me.

"After dinner, I'll go back to your room and talk to you in detail, Feng Yuan panicked at this time, I picked up this page of newspapers, and I didn't throw away the rest, Feng Yuan must have seen other newspapers from the car just now, if nothing else, this will be peeking over here."

I deliberately turned my head to look at the kitchen, put my hand to my mouth and whispered.

"Look at it that afternoon, don't let that kid be bad again."

Cao Hua said as he picked up the water and glanced out the window.

"Do you remember the first time I went to the city, and I ran into the motorcycle that was hit by a taxi?"

I asked.

"Well, what's the matter, isn't the driver missing?"

Cao Hua responded.

"I'm running into it today, I'm a living corpse, and I'm wearing a helmet."

I sighed.

"Haha, then it's pretty high-defended."

Cao Hua quipped.

"The head-on shot scared me out of nowhere, not far from here."

I took a sip of water and continued:

"Five kilometers at most, I don't know how to run here."

"Actually, the taxi before came to us, and the straight-line distance was only five or six kilometers, right? There hasn't been any big movement recently, at most, Da Yue has whistled in the yard, although it is quite loud, but it will not attract living corpses from so far away, it is estimated that they are swaying around here......"

Cao Hua said and frowned:

"If there are still living corpses wandering around here, they are probably all cats nearby."

What Cao Hua analyzed is exactly what I am worried about.

"This is a big hidden danger, we have to think of a way, and we will deal with it after these two days, and the first thing that needs to be done now is to get a prison out."

I lowered my voice again:

"Feng Yuan will definitely be locked up, just the hut at the gas station, eat, drink and Lasa in it, and I don't know what it will be dirty after a while."

"Don't wait for them to turn the prison into a toilet, just give them a toilet and let them be a prison, and just change the public toilet and it's over."

Cao Hua looked at me, as if he was joking, and as if he was talking about business.

But I'm not surprised, in addition to this main building, there are gas stations and public toilets, so the analysis of the public toilet is the most suitable, there is water in it, you can go to the toilet, as long as they keep hygienic, there is no problem to live, the main thing is to do a good job of defense measures.

"Well, there are doors and windows itself, and the fence of the truck is removed, fixed on the outside and sealed."

I described my plan.

"The question is again, how to fix the big engineer?"

Cao Hua also learned to be smart this time, and he didn't want to do useless work anymore.

"I went to the city again in the afternoon, and when I was looking for a newsstand today, I saw a few hardware supermarkets, and I directly took a percussion drill and expansion screws to fix it for him, and I wanted to get some tools by the way, and I almost explained it to me when I found the newspaper."

Saying that, I described to Cao Hua about encountering corpses with newspapers, and Cao Hua fell into deep thought after listening to it.

"You say, the sound can attract them all, why don't we just give them all out, and then kill them all."

After being silent for a long time, Cao Hua held back such a call:

"You said that they have been nesting here all the time, and they will run this way if there is a little big movement, why is it not safe."

Cao Hua really dared to think.

Although I had a similar thought, I had a similar thought, but after experiencing the previous train, this idea was put down.

"Remember the time the train was burned? An explosion, coupled with a fire, he attracts not a group of corpses in a single direction, but all living corpses within a radius of how many kilometers, how far this sound can travel, we don't know, there are no corpses around our safety zone, and it's not clear, really use the sound to attract, and then there are passing corpses, we really have nowhere to hide. ”

I told Cao Hua about my scruples.

Cao Hua nodded continuously after listening to this, muttering:

"It's a tricky thing......

"But it's not impossible to achieve, you said that this sound, if you can do it, you can control its size, and then calculate its propagation speed, roughly how far it can travel, it should be able to be calculated, right?"

I looked at Cao Hua, who was constantly touching his chin, and said tentatively:

"The people who can calculate these things, in our group, it seems that there are only ......"

"Wang Dongru!"

Cao Hua patted his head and suddenly realized.

However, his shout really startled me, and Wang Dongru, who was sitting in the distance, also hurriedly stood up and asked nervously:

"How...... What's the matter, Brother Cao......"

I found out that the women in the restaurant were gone, so I guess I ran upstairs to try on clothes......

I hurriedly beckoned Wang Dongru over:

"Come to Wang Dongru, can you calculate the volume of the sound and the distance it travels?"

Wang Dongru sat down and pushed his glasses:

"This is easy to calculate, there is a formula, but the results of the calculation are theoretical data, the same sound in the air propagation distance will be different, the actual distance also refers to the wind direction and wind speed and other objective factors, and the density of the air such as altitude will also be different, so the scientific calculation method is based on a certain fixed medium as the premise......"

"Just take the air, how big is the error?"

The more I listened, the more confused I became, so I simply interrupted Wang Dongru and asked.

"Depending on the sound volume and travel distance, and then referring to the wind direction and wind speed, you should be able to estimate the approximate range of error."

Wang Dongru has adapted to being interrupted by me during popular science.

"This thing has to be planned, is there any way to make and maintain the volume of this sound, and keep it going for a long time, and it doesn't need to be guarded?"

I continued to ask questions.

"This is okay, the easiest way is to make a big speaker, continue to play the same audio, if you keep the power to use solar panels, I can do this, it's just ......"

Wang Dongru was a little troubled.

"Tell me, what do you need?"

At the very least, it can ensure the safety of the service station, and at the very least, it can save the world, and I have to find a way to get what he needs.

"There is no sound decibel tester, I had that software on my phone before, but it was deleted, and now there is no network and I can't download it, so I ......."

Wang Dongru was a little embarrassed.

"Just tell me where you can buy it, right?"

I've never heard of it, and I don't know where to get it.

"Bigger hardware stores, some home goods stores will also have them."

Wang Dongru said.

"Okay, I'll bring it to you in the afternoon, tell me what else you want."

I continued to ask, and I was going to the hardware store in the afternoon, so I did it.

"I'll write it down on paper for you, I'm afraid you won't remember it then......"

Wang Dongru ran out as he spoke, found a pen from the bar, dragged a piece of paper, and after a while, handed me a list.

As soon as I looked, the good guy had to let him write it down, otherwise he wouldn't be able to understand these terms, let alone memorize them.
