Chapter 595: Sound lures away zombies, doesn’t work anymore?

Big camphor tree base.

inner city.

Li Yu quietly looked at the black snowflakes dancing outside the window in the room.

It snowed continuously, and in the base, the snow on the ground reached 20 to 30 centimeters thick.

On the sidewalks, people clean up the walking areas every day.

Li Yu sat down slowly in the room, the water in the cup in his hand still steaming.

The wind outside the window was blowing naturally, driving the snowflakes to fall to some corners.

These days, almost every few days, he would sit in the meditation room in the basement to adjust his low mood.

The dark night has a great influence on people.

The people on duty at the fence today are Li Tie and Li Hang.

The zombies under the wall have not disappeared. The mobile gate knife is like a machine that regularly cleans out zombies. It is turned on at regular intervals and then kills some zombies. These killed zombies will immediately be devoured by other zombies.

During this period, the staff on duty at the fence are least stressed.

In recent days, I haven’t heard much of the chirping of insects and birds.

Li Tie, Li Hang, and Liu Jinglue were outside the duty room at the gate, shooting zombies with crossbows as a small competition.

Take ten zombies as one shot and see who has the highest hit rate.

"Brother Tie, Brother Hang, you come first, I'll go back to the duty room to drink some water." Liu Jinglue said to the two of them.

The two nodded, indicating that it was okay.

Liu Jinglue walked to the duty room with the crossbow in his hand.

The heating was turned on in the duty room, and as soon as I entered, I felt a wave of heat.

Liu Jinglue shook off the snow on his body at the door. He didn't want to get the snow into the duty room, which would make cleaning it troublesome.

The hat was hung in a fixed position at the door. He walked to the water dispenser, took out his thermos cup and screwed on the lid. The water in the thermos cup also had a temperature. Liu Jing briefly tested the temperature, blew on it, and then took a sip. .

His eyes casually glanced at the monitoring screen.

Um?

Outside the base, a number of surveillance cameras are installed on both sides of the national highway.

On the surveillance screen, densely packed zombies were walking slowly.

puff--

Liu Jinglue took a sip of the water he had just drank and spurted it out instantly.

He immediately put down the thermos cup in his hand, rushed to the door of the duty room, and shouted to Li Tie and the others: "Come quickly, I discovered something."

At this time, Li Tie happened to shoot his bow and arrow. When he heard Liu Jinglue's words, he asked doubtfully: "What?"

At the same time, he put down the crossbow and walked towards the duty room with Li Hang.

In the duty room.

The three of them looked at the zombies on the surveillance screen, and their eyes widened.

In the past, some zombies would come, but never so many.

On the surveillance screen, the entire national highway was filled with zombies, and the end could not even be seen.

Some zombies sniffed the air and walked straight towards the rural road. Other zombies seemed to have smelled the human scent, and more and more zombies were coming this way.

"Xiaohang, press the alert button." Li Tie said without hesitation.

Then he took the walkie-talkie to notify others.

Throughout the camphor tree base, figures flashed, and many people ran out of the room and ran towards the wall.

After hearing Li Tie's notice, Li Yu immediately rushed to the wall from the room, put on protective gear.

On the way to the wall, came across the cannon.

He didn't even wear his cannon hat. He put his hat under his arm and ran towards the wall while putting on his raincoat.

Seeing Li Yu who also rushed out of the room, Da Pao said, "Brother Yu, do you know what's going on? I was just sleeping when I heard the alarm."

Li Yu said while running: "A zombie wave broke out! This time the zombie wave is probably not small."

His brows were full of solemnity. According to what Li Tie said just now, the entire national highway is covered with no end in sight. The number must be very terrifying.

Arriving at the steps behind the barbican, Li Yu and Da Pao had already heard the roar of zombies.

resounded throughout heaven and earth.

The two looked at each other in horror.

After rushing up to the wall, Li Yu took a telescope and looked outside.

In the blurry night, you can see a large number of zombies coming densely over the mountain forest.

The roars were continuous.

Li Tie saw Li Yu coming and came over quickly: "Brother, I don't know what happened, but these zombies suddenly appeared. It was very sudden."

Li Yu nodded slightly and felt a strong sense of oppression when he saw the sudden increase in zombies under the wall.

Seeing the people coming up from below, Li Yu shouted to them: "Everyone, be prepared to resist the zombies. Don't let a zombie enter the wall."

This is not the first time that everyone has encountered a zombie wave. Although there have not been so many zombie waves before, the walls were not so high at the time.

Ho ho ho——

The zombies under the wall are very sensitive. The zombies behind can even rush over by stepping on the zombies in front.

In just a few minutes, the zombies under the wall were like a hornet's nest being poked, everywhere.

There was a trench six to seven meters deep outside the wall, which was instantly filled with zombies.

The distance from the wall to the mountain forest was about forty or fifty meters. This distance of forty or fifty meters was packed with zombies, as if they were like sardines, without any gaps.

What’s even more terrifying is that after this, there is still no end in sight.

These zombies continued to flow towards other directions of the wall.

Seeing this scene, Li Yu felt a little palpitated, and then asked everyone to take out their heavy weapons and prepare for battle.

Wind blows.

In less than five minutes, the zombies were stacked to a height of eight or nine meters.

Li Yu ordered to open the mobile switch knife.

Kakaka——

Move the knife from slow to fast, and at the end the speed is getting faster and faster.

The ruthless blade cut off the zombies one by one.

The other zombies below, seeing the falling corpses, rushed up to snatch and devour them.

The zombies in the back rushed towards the wall even more excitedly.

In the past, when there were not so many zombies, as long as the mobile knife was turned on and some zombies were killed, the zombies below would naturally grab them, and then the height of the stack would also decrease.

At this time, because there were too many zombies, the corpses of the falling zombies had not been eaten, and the zombies that were not grabbed behind rushed up.

As a result, the height of the zombie stack did not drop.

The moving knife, which was supposed to be turned on for a few minutes and then stopped, this time, it just didn't stop.

A height of eight meters to 12 meters is a battlefield of hell.

Countless zombies rushed up tirelessly, and were cut off by the moving knife.

However, the zombies rushed up too fast.

The stacked zombies gradually covered the mobile knife. Too many zombie corpses overwhelmed the mobile knife.

When He Bing saw this scene, he immediately said to Li Yu: "Mr. Li, we must close the mobile knife immediately. The zombies are too fast now and have exceeded the load of the knife. There are so many zombies pressing on the knife. It is very difficult." It’s possible to get stuck, and it’s difficult to carry the weight of so many zombies.”

Li Yu naturally knows.

The main reason that hinders the function of the mobile knife is that there are too many zombies rushing from behind, and there is no chance for the mobile knife to deal with the zombies.

The main problem at the moment is not the zombies at the wall, but the zombies dozens of meters away.

The speed of their attack must be controlled, otherwise, based on this situation, they would be able to stack up to the same height as the wall in less than ten minutes.

"Detonate the mines buried outside the mountains and forests. Stop them first." Li Yu said to Li Tie.

At first they obtained some bombs and landmines in the arsenal. These mines are buried tens of meters between the mountain forest and the base.

The purpose is that when the number of zombies reaches a certain level, they can explode in a wave to gain time.

At this time, it is the right time for the mine to detonate.

Li Tie's eyes widened. He didn't expect to use this so soon.

So rushed to the duty room.

Find a key from a box and open an iron cabinet hanging on the wall.

See a row of buttons on the iron cabinet.

Li Tie hesitated for a second and shouted to everyone outside the duty room: "I'm going to detonate it."

Outside the duty room, there were dozens of people, including third uncle, second uncle, uncle, Lao Qin, and Lao Luo.

They covered their ears with their hands and squatted down.

Li Tie saw them squatting down, gritted his teeth, and pressed six buttons in three seconds.

Then he quickly leaned against the wall and covered his ears.

The next second.

Boom, boom, boom

The earth shook!

The tall wall was also shaken, and the snow on the wall stacks was shaken down.

The zombie's limbs and arms flew to the wall.

Bang bang bang bang~

The explosion lasted for nearly ten seconds.

The deafening sound made everyone on the wall feel tinnitus.

Ten seconds later, the explosions stopped.

Li Yu shook his head and stood up slowly.

About ten meters away from the wall and thirty meters into the forest, there were only a few scattered zombies standing.

The explosion burned the zombies, there were small flames everywhere, and the air was filled with the smell of rotten meat being barbecued, making people want to vomit after smelling it.

There are still many zombies on the other side of the forest.

They rushed towards the corpses of zombies that were killed within thirty meters.

Bite and devour.

These zombies clinging to the wall, without the follow-up zombies, the pressure on the moving knife dropped sharply. The moving knife, which had just been pressed and stuck by many zombies, also exerted its power at this time.

The zombies that had climbed to a height of 14 meters continued to collapse like a castle built with sand.

Finally, it collapsed to a height of only five or six meters. After these zombies fell down and saw zombie corpses all over the ground, they stopped climbing the wall and continued to devour the zombie corpses.

Seeing this scene, Li Yu breathed a sigh of relief.

While things were slowing down a bit, Li Yu said to Li Gang and others: "Go and take out the drone, and use the radio to lure away some of these zombies. There are too many zombies."

Li Gang and Yang Tianlong ran to get the drone.

A total of four drones were brought, each with a speaker.

"Hurry up and put the drones out, try to lead them to the national highway and lead them away." Li Yu said eagerly.

Buzz——

A drone flew up, followed by a second, a third, and a fourth.

After the drone took off, it flew towards the national highway.

drop--

The drone sounded, and there was a searchlight in front of the drone, illuminating the situation ahead.

However, the sound of the drone did not make the zombies leave immediately. They raised their heads and roared on the spot.

Everyone who saw this scene felt their hearts skip a beat.

A trick that had always worked well before failed to work now.

"Fly to the national highway." Li Yu said.

The drone flew outside, but the zombies on the national highway stopped in place for a moment when they heard the sound in the air. They seemed a little confused.

In this dark and snowy environment, the zombies' sense of smell and hearing have reached an abnormal level.

They have an extremely abnormal sense of smell and can clearly detect the presence of a large amount of human scent on the country road.

But the sound in the air also greatly stimulated them.

There was a dense tide of zombies. Some zombies ignored the voice and continued to rush towards the rural road.

Some zombies stretched out their hands to catch the drones in the air.

Seeing this scene, Li Gang excitedly controlled the drone to fly to the side of the national highway.

More and more zombies were following behind, Li Gang secretly thought with a face full of joy, and continued to control the drone to fly further south.

Other drones also cooperated with each other, constantly luring zombies to follow them on the rural roads.

But they soon discovered that the closer they were to the base, the fewer zombies would choose to follow the drone.

The further away from the base, the higher the chance of choosing to follow the drone.

The four drones cooperated with each other to lure the zombies to fly south.

But soon, they desperately discovered that these zombies were following them for a certain distance.

As long as the horn sound is turned off, these zombies will return to their previous location and follow other zombies to attack the base.

The method of luring all the zombies away is bankrupt.

Li Gang and the others were a little discouraged.

Li Yu was not too surprised by this result. He tried to treat a dead horse as a live doctor and give it a try.

"Don't be discouraged, turn off the drone horn, fly back, and then let the four drones fly out in turn."

"Brother, these zombies that were lured away will come back later. It doesn't make much sense for us to do this."

Li Yu looked at the zombies outside the wall. They were devouring them very quickly. In just a moment, less than half of the zombies killed by the explosion were eaten.

"Who says we can't lure away all the zombies? It's useless. This drone can at least reduce our burden. It's difficult to face 100,000 zombies at the same time in one hour. It's still 10 hours. If we spread out, we can face 10,000 zombies. Is it difficult only for zombies?"

After Li Yu's reminder, Li Gang suddenly woke up.

Yes, as long as some zombies can be lured away, even if these zombies will come back again, it will buy the base time to kill the zombies.

Not to mention anything else, just in that moment, he attracted at least thousands of zombies.

And this sound can disrupt the judgment of some zombies.

This prevents them from rushing directly into the rural road, which greatly alleviates the dilemma on the base wall.

"Okay." Li Gang put the drone that had just run out of power back into the duty room to charge, then took out another drone and flew out.
