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."
Li Yu heard this and 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, and how 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 flashed twice and then lit up.
She skillfully walked to the test bench 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 mankind has become increasingly difficult.
"How's it going?" Li Yu couldn't help but ask after sitting and waiting for ten minutes.
Bai Jie and Ma Di 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. Sunlight and water must be present."
"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 capture a few of the mutant zombies there and study them."
He got up from the chair and continued to say to the two of them:
"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 dawn soon.
"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 fainter.
He carried Starlight 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 it had been a long time since the city lord had gone out to perform a mission in person.
At the same time, I also felt some pressure.
Cannon was not on duty today, but he was called up by Li Tie and went with him.
Hearing that there was such an exciting mission, Cannon was woken up at 5:30 in the morning. After cursing, 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 had a better understanding of the cave.
Time flows slowly.
Everything is being prepared.
At half past five in the morning, it was already bright, but the sun did not come out.
At six o'clock, the sun rises from the east, and smoke curls up from the base.
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 will definitely have to make this trip, after all, those electric trucks are still there.
As for whether to continue mining limestone there, we have to make a judgment based on the conditions of the cave.
Half past six 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 boarded the helicopter with Li Tie and others.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! The rising sun shines on the helicopter, reflecting golden light.
Among the big camphor tree base.
The sun rises slowly, its light shines warmly on the earth, and everything begins to wake up.
A little bird jumped down from the branch and flew into the sky, singing happily.
A petal fell gently on the grass, dancing in the breeze.
Buzz buzz——
Seven or eight helicopters floated into the sky.
Lao Bi and the others had been to the underground cave yesterday, so they knew the way, so they could go there much faster now.
After a journey of more than fifty kilometers, it only took ten minutes to arrive near the limestone mine with the helicopter flying at full speed during the day.
On the empty flat land under the ore mountain, there was no zombie left.
But the electric trucks that were left behind were pushed around, and Yu Wei broke into a cold sweat when he saw the electric trucks below.
Without the support from the headquarters base last night, it might be difficult for them to hold on until dawn.
"Flying past these mines, we are right in front. But there is no suitable place for the helicopter to dock. City Lord, how about we stop here at the mine?" Lao Luo asked Li Yu using the walkie-talkie.
"Well, just do as you say."
After hearing this, Lao Luo asked the helicopter team to land from the sky.
During the day, when the sun is high and the weather is hot, zombies generally don't like to come out.
The sky is bright, they can see clearly, and even if zombies come, they can suppress them with firearms.
The helicopter slowly landed in the open space next to the truck. After the eight helicopters landed, there was still an aisle in the middle.
This is also considered to facilitate the passage of electric trucks.
They can't drive helicopters directly to the underground cave, but they can drive vehicles there.
Li Yu unbuckled his seat belt and got off the helicopter.
swish swish——
He stepped on the gravel and sand, making a soft sound.
There was a smell of lime in the air, which was a bit offensive.
"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 getting off the helicopter opposite.
"Okay, then I will bring a dozen people to watch here. City Lord, please be careful." Lao Luo nodded and replied, pointing to the second floor.
After Yu Wei got off the helicopter, he immediately ran to the electric truck.
Li Tie worked with them to turn off the ultraviolet light that had been on all night.
The ultraviolet lamp that shines all night does not consume much power of the electric vehicle.
I checked the electric truck and found that there were basically no problems except for some scratches on the outside of the body by zombies.
Li Tie and others drove an electric truck over and stopped in front of Li Yu and others.
"You guys go first." Li Yu waved to Lao Bi and others.
Lao Bi and the others removed all the explosives from the helicopter and put them in the truck.
After getting in the car, he directly controlled the drone to take off and fly towards the underground cave two kilometers away.
Li Yu and Lao Bi Baijie were riding in a truck.
Li Gang drove the electric truck himself. There were four or five electric trucks in front of them and two behind them.
This time sixty combatants came out, all of whom were the most experienced combatants in the base.
Except for those collaborators, everyone else was wearing uniform black combat uniforms, with a small tree symbol tattooed on the chest of their combat uniforms.
This is the unique logo of their Da Zhangshu Base.
After the drone took off, it bypassed the limestone mountains and went around to the right.
They followed the drone closely, rolling over the overgrown ground and driving slowly away.
The weeds on the ground were trampled flat, these are the traces left by the zombies walking by.
The electric truck drove almost silently, bypassing the tall limestone mines, and after driving for another two kilometers, there was a sparse forest in front of it.
Crunch!
The electric truck stopped suddenly.
Lao Bi pointed to the woods ahead and said to Li Yu:
"City Lord, the underground cave is behind the woods. Let's stop here."
"Well, let's control the drone first and go in for reconnaissance."
"good."
Lao Bi raised his hand to Qu Xing and others and waved in the direction of the underground cave.
Wuwuwu——
The drone droned low, passed over their heads, and flew towards the woods.
Soon we flew to the entrance of the underground cave.
Li Yu looked at the screen on the drone control panel, which showed a hole about seven or eight meters long and eight or nine meters wide.
Qu Xing controlled the drone and lowered its altitude.
Hovering at the entrance of the cave, sunlight sparsely shined through the leaves a few meters inside the cave.
It gets darker as you go inside.
He Chao looked at the familiar cave entrance and said, "Yes, this is it. After entering here, there is a platform. It is very big inside. If you fly forward, you will go down."
The spotlight on the drone was turned on, shining into the cave.
As He Chao said, inside the cave, after passing more than ten meters, a huge space appeared.
The height of this platform is at least twenty or thirty meters. When the light shines on it, it looks like it has been swallowed up. It is not very realistic.
Wuwuwu——
Yu An, Li Tie and others used this to control the drone to fly in. Under the illumination of nearly ten drone overhead lights, the space became much clearer.
Under the cave, there are countless zombies standing densely. These zombies all have white skin, which is somewhat reflective under the spotlight.
Perhaps it was the stimulation of the light that made these zombies restless.
Ho ho ho!
On the roof of the cave, there are several rows of bats hanging upside down.
The roars of the zombies caused these bats to move and fly 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 was unable to dodge and was hit head-on by a bat. It flipped over and was unable to control the drone.
He fell down among the zombies.
Bah!
The last picture displayed on the screen of this drone was that it was robbed 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 randomly, all the drones may crash.
Now their Da Zhangshu base cannot produce drones at all, and can only repair them at most. The main reason is that they lack core chip components, which are difficult to obtain in the apocalypse.
Therefore, if one drone crashes, there will be one less drone.
Qu Xing and others immediately controlled the drone to turn off the spotlights and turned on the night vision mode.
In night vision mode, the display on the screen is not that clear.
In order to see more clearly, they also built an awning above their heads, so that they can see more clearly in dark spots.
After the lights were turned off, the zombies below gradually regained their composure, and their roars stopped.
The bats flying around in the cave gradually returned to hang upside down on the roof of the cave.
call--
After Qu Xing saw this on the screen, he breathed a sigh of relief.
"Keep flying forward." Li Yu said sitting next to him.
At this time, Lao Bi saw a few ordinary zombies coming out of the woods.
But there are no other zombies behind.
"City Lord, look, there are zombies coming out."
Li Yu saw these zombies coming out of the woods and said, "Use cold weapons to deal with them. Don't shoot, otherwise you will draw out all the zombies in the cave."
"Okay." Lao Bi got out of the truck and took people there to solve the problem himself.
"etc."
Li Yu stopped Lao Bi, pointed at the explosives in the car in front, and said:
"Take someone with you and put the explosives at the entrance of the cave. If something unexpected happens, we will blow up the entrance and the zombies will not be able to come out. It will be safer for us to stay here."
Lao Bi nodded, called over twenty combatants, carried explosives on their backs, and walked towards the woods.
