Chapter 1390 Bats in the Cave

"City Lord."

After completing the inspection, Bai Jie walked up to Li Yu and said:

"I want to go back to the scientific research institute first. The wall-climbing zombies sent from Oil City last time have done some experimental tests. I want to see the experimental registration form."

Hearing this, Li Yu asked attentively: "Have you discovered anything?"

"There are some guesses, but not very certain. We have to see the test data report to be sure."

Hearing what she said, Li Yu quickly said:

"Okay, then you go back first."

"I'll go with you."

He wanted to know what kind of changes those zombies had. The changes in the zombies would affect their future layout.

Afterwards, Li Yu, Bai Jie, Ma Di and others entered the outer city and then entered the scientific research institute.

The inside of the scientific research institute is dark.

Bah!

Bai Jie turned on the incandescent lamp.

Sizzling——

The incandescent light flickered twice and then lit up.

She skillfully walked to the test table and took down the experiment registration form on the wall.

Then carefully compare the previous test results.

Ma Di cooperated with her, and the two of them spoke some professional terms that Li Yu couldn't understand.

While the two were discussing, they occasionally walked over to the wall-climbing zombies sent over from Oil City to observe.

Li Yu sat next to him and waited quietly, his mood ups and downs.

The zombie antidote has not yet been developed, but the zombies are constantly changing.

Natural disasters continue, and more and more survivors cannot survive these natural disasters.

Under the circumstances, the situation of human beings is becoming more and more difficult.

"How's it going?" Li Yu couldn't help asking after sitting and waiting for ten minutes.

Bai Jie and Madi looked at each other, and she came over with the experimental data report.

"City Lord, the mutation of zombies is not only related to the amount of eating corpses of the same kind, but also related to the heavy rain environment."

"Continue." Li Yu frowned.

Bai Jie continued:

"After the three zombies that had not yet fully mutated were transported here from Oil City, we observed these zombies and found that these three zombies did not change over time and continued to mutate into complete wall-climbing zombies. "

"Later we fed some zombie corpses to them, but the mutation effect was minimal."

"So we infer that these zombie mutations require two conditions. One is to eat the corpses of the same kind to obtain more viruses, and the second is to be exposed to heavy rain."

"Just like a plant growing, it cannot grow if only fertile soil provides nutrients. It must have sunlight and water."

"The corpses of the same kind are like soil, providing mutated nutrients to these zombies, and heavy rain is the environment."

Li Yu nodded when he heard this, but he suddenly remembered the situation at the cave in Hefeng Town.

"Why are there so many mutant zombies in Hefeng Town? The probability of mutant zombies appearing was not so high before?"

Madi thought for a moment and said:

"That cave is very big, so there must be a lot of zombies. If the base number is large, there will be more mutant zombies."

Bai Jie frowned and said, "I don't think it's that simple. It may have something to do with the underground river in the cave."

"And I just heard from Yu Wei that the high-jumping zombies they found can already jump to a height of two and a half meters. This is much higher than before, and this is not normal."

Li Yu took a deep breath. This matter was so foggy that he still hasn't figured it out yet.

"Stop arguing, just go to the cave together tomorrow. We'll find out after we catch a few of the mutant zombies there and study them."

He got up from the chair and continued to say to the two people:

"That's it for today. You guys should go to bed early."

I looked at the time, it was almost five o'clock.

It will be daybreak in a while.

"It's already five o'clock. Forget it, don't take a rest. Pack up all the testing equipment and everything. We'll set off in an hour and a half."

"Yes." The two nodded.

Li Yu left the scientific research institute and looked up at the starry sky. It was no longer so dark.

The stars also became much lighter.

He carried Xingguang on his back and quickly returned to the outer city.

"Second uncle, I plan to go to Hefeng Town with Bai Jie and the others after dawn. Hefeng Town is very close to our base. If this happens, I have to go there and find out in person."

When the second uncle heard that Li Yu was going there in person, he hesitated to speak, and finally said one word: "Okay."

"Um."

Li Yu immediately asked Li Tie, who was on night shift, to bring out several hundred kilograms of explosives from the warehouse.

No matter what happened in that cave, the entrance to the cave must be blown up in the end, otherwise so many zombies inside would be a hidden danger.

In addition, Li Yu ordered Lao Luo and the others to bring more than a dozen drones and install spotlights and night vision devices on the drones.

In this way, they don't have to risk entering the dark cave.

After learning that the city lord was going there in person, Lao Luo and Lao Bi were a little surprised, but also a little emotional. They felt that the city lord had not gone out to perform tasks in person for a long time.

At the same time, I also felt some pressure.

Cannon was not on duty today, but he was called up by Li Tie to go with him.

Hearing that there was such an exciting mission, Cannon was woken up at 5:30 in the morning and cursed. He quickly changed into a smile, put on his combat uniform and hurried over.

He Chao also wanted to go together. After all, he had entered this underground cave before and knew more about the cave.

Time flows slowly.

Everything is being prepared.

At 5:30 in the morning, the sky was already bright, but the sun did not come out.

At 6 o'clock, the sun rose from the east, and smoke from the base was curling.

On the helicopter in the outer city, Li Tie and others had prepared the explosives and drones they were going to bring.

Yu Wei and others must go there again this time, after all, those electric trucks are still there.

As for whether to continue mining limestone there, it depends on the situation of the cave.

At 6:30 in the morning.

Li Yu walked out of the inner city, and everyone was ready.

After a brief chat with his second uncle, Li Yu got on the helicopter with Li Tie and others.

The rising sun, the sunlight shines on the helicopter, reflecting the golden light.

In the camphor tree base.

The sun rises slowly, the light shines warmly on the earth, and all things begin to wake up.

A little bird jumped from the branch and flew into the sky, singing happily.

A petal gently fell on the grass, dancing with the breeze.

Buzz buzz buzz --

Seven or eight helicopters floated into the sky.

Lao Bi and his team had been to the underground cave yesterday, so they knew the way and could go much faster now.

It took only ten minutes to reach the vicinity of the limestone mine with the helicopter flying at full speed during the day.

There was no zombie on the open flat ground under the ore mountain.

But the electric trucks that stayed were pushed all over the place, and Yu Wei broke out in a cold sweat when he saw the electric trucks below.

If they hadn't had the support of the headquarters base last night, they might have had a hard time holding on until dawn.

"Fly over these mines and it's right in front. But there's no suitable place for helicopters to park over there. City Lord, why don't we stop here at the mine?" Lao Luo asked Li Yu using the intercom.

"Well, just do as you say."

After hearing this, Lao Luo let the helicopter team land from the air.

During the day, the sun was high and the weather was hot, so zombies generally didn't like to come out.

The sky was bright, so they could see clearly, and even if zombies came, they could suppress them with guns.

The helicopter slowly landed on the open space next to the truck. After the eight helicopters landed, an aisle was still left in the middle.

This was also to facilitate the passage of those electric trucks.

They couldn't drive the helicopter directly to the underground cave, but they could drive the vehicle over.

Li Yu unbuckled his seat belt and got off the helicopter.

Shashasha——

He stepped on the gravel and sand, making a light sound.

The air was filled with the smell of lime, which was a bit pungent.

"Lao Luo, take people to watch these helicopters. Lao Bi and I will take a car to the underground cave." Li Yu shouted after seeing Lao Luo on the opposite side get off the helicopter.

"Okay, then I'll take a dozen people to watch here. City Lord, you guys should be careful." Lao Luo nodded and replied.

After Yu Wei got off the helicopter, he immediately ran to the electric truck.

Li Tie and the others turned off the UV light that had been on all night.

The UV light that had been on all night did not consume much power from the electric car.

After checking the electric truck, except for some scratches on the outside of the car body by zombies, there were basically no other problems.

Li Tie and the others drove the electric truck over and stopped in front of Li Yu and others.

"You go first." Li Yu waved to Lao Bi and others.

Lao Bi and the others took all the explosives from the helicopter down and put them in the truck.

After getting on the car, they directly controlled the drone to take off and flew towards the underground cave two kilometers away.

Li Yu, Lao Bi, Bai Jie and others took a truck.

Li Gang personally drove the electric truck. There were four or five electric trucks in front of them and two behind them.

This time, sixty combatants came out, all of whom had the most combat experience in the base.

Except for those cooperative personnel, everyone else wore a uniform black standard combat uniform, and on the chest of their combat uniforms, there was a small tree mark.

This is the unique logo of their big camphor tree base.

After the drone took off, it bypassed the limestone mountains and went around from the right.

They followed the drone, rolling over the weedy ground and driving slowly.

The weeds on the ground were trampled flat, which were all traces left by the zombies.

The electric truck was almost silent, bypassing the tall limestone mines, and drove another two kilometers. There was a sparse forest in front.

Creak!

The electric truck stopped suddenly.

Lao Bi pointed to the forest in front and said to Li Yu:

"City Lord, the underground cave is behind the forest. Let's stop here."

"Well, control the drone to go in and investigate first."

"Okay."

Lao Bi raised his hand to Qu Xing and others and waved in the direction of the underground cave.

Woo woo woo——

The drone hummed low, passed over their heads, and flew towards the woods.

Soon it flew to the entrance of the underground cave.

Li Yu looked at the screen on the drone control console, which showed a cave about seven or eight meters long and eight or nine meters wide.

Qu Xing controlled the drone and lowered its altitude.

It hovered at the entrance of the cave, and the sunlight sparsely sprinkled through the leaves a few meters into the cave.

It became darker as it went deeper.

He Chao looked at the familiar cave entrance, "Yes, it's here. There is a platform after entering here. It's very big inside. If you fly forward, you will go down."

The spotlight on the drone turned on and shone into the cave.

As He Chao said, the cave was indeed as huge as it was. After passing through more than ten meters, a huge space appeared.

This platform is at least 20 to 30 meters high. The light shining inside seemed to be swallowed up, and it was not very clear.

Woo woo woo——

Yu An, Li Tie and others controlled the drone to fly in. Under the illumination of nearly ten drone spotlights, the space became much clearer.

Under the cave, countless zombies stood densely. These zombies all had white skin, and under the illumination of the spotlights, some reflected light.

Perhaps it was because of the stimulation of the light that these zombies became restless.

Roar!

And on the top of the cave, there were several rows of bats hanging upside down.

The zombies' roars caused these bats to move abnormally, and they flew around.

Qu Xing and others quickly controlled the drone to fly to the edge to prevent it from being hit by flying bats.

Boom!

A drone failed to dodge and was hit head-on by a bat. It flipped over and lost control of the drone.

It fell into the zombie group.

Boom!

The last picture displayed on the screen of this drone was that it was snatched by several zombies and completely disintegrated.

"Turn off the lights! Turn on the night vision goggles!" Li Yu said quickly.

If the bats are allowed to fly around again, all the drones may crash.

Now their big camphor tree base can't produce drones at all. At most, they can only repair them. The main reason is that they lack core chip components, which are difficult to get in the end of the world.

So, one less drone crashed.

Qu Xing and others immediately controlled the drone to turn off the spotlight and turned on the night vision mode.

In the night vision mode, the display on the screen is not so clear.

In order to see more clearly, they also built a sunshade above their heads, which can be seen more clearly in a dark environment.

After the lights were turned off, the zombies below gradually calmed down and the roars stopped.

The bats flying around in the cave gradually returned to the top of the cave and hung upside down.

Huh——

Qu Xing breathed a sigh of relief after seeing this scene on the screen.

"Keep flying forward." Li Yu said as he sat next to him.

At this time, Lao Bi saw a few ordinary zombies coming out of the woods.

But there were no other zombies behind.

"Lord of the city, look, there are zombies coming out."

Li Yu saw these zombies coming out of the woods, "Use cold weapons to deal with them, don't shoot, otherwise you will lure all the zombies in the cave out."

"Okay." Lao Bi was about to get off the truck and lead people to deal with it personally.

"Wait."

Li Yu called Lao Bi, pointed at the explosives in the car in front, and said:

"Take your men to take the explosives and put them at the entrance of the cave. If there is any unexpected situation, we can blow up the entrance of the cave and the zombies can't come out. It's safer for us to stay here."

Lao Bi nodded, called more than 20 combatants together, and walked towards the woods with explosives on their backs.
