Over BY City, two helicopters are flying.

Except for the pilot, everyone in the helicopter focused on the ground in BY City, trying to find traces of humans.

The judge looked at his watch. Time passed slowly, and the fuel in the helicopter continued to be consumed.

They can't stay here that long, and it would be more efficient for the two helicopters to disperse.

So he pressed the intercom to contact Nuts and the others:

"Nuts, let's search separately and notify each other if we find one. If we don't find it, we'll gather here later and return to Oil City together."

"Received." Nuts replied, and then gestured towards the driver Ma Dong.

Ma Dong also heard what the judge said and nodded.

He controlled the helicopter, made a big turn, and flew in the opposite direction.

Helicopters shuttled over the city, and zombies on the ground could be seen from time to time. When these zombies heard the sound of the helicopter, they raised their heads and roared.

However, it is too high, and these zombies can do nothing but roar.

As time passed, there was still no trace of the person who administered the medicine, which made the judge quite anxious.

Half an hour passed by in a blink of an eye, but I still couldn't find it.

Even though the judge was reluctant, he knew he had to leave.

Although they can stay in BY City to continue their investigation, this place is close to the northwest after all. If someone from the northwest discovers them, it will be very troublesome for them to leave.

Moreover, there are these terrifying zombies in BY City, so it is unwise to stay here.

"Nuts, stop looking. Let's return." The judge said through the intercom.

After hearing the judge's words, Nuts looked at the ground below with some reluctance, "Copy that, I'll return now."

Ma Dong heard the conversation between the two and flew the helicopter to the agreed place.

Soon, Nut saw a helicopter flying from the west.

They followed the judge and flew towards Oil City.

In a helicopter.

The judge reported the situation here to his third uncle and gave his own guess.

The black-red liquid, plastic film, and glass jar were obviously left behind by people.

This red liquid smells strongly of blood, and it must have been mixed with a lot of blood.

Coupled with the mutant zombies that appeared here, he guessed that these liquids were the cause of the changes in the zombies here.

The third uncle listened to his report. When he heard someone dropped an unknown liquid and attracted a large number of zombies, he immediately opened the map.

BY city is only 80 kilometers away from Wuyuan Mountain in Malaoliu.

If the liquid was artificially injected, this Ma Laoliu would definitely be the first person to be suspected.

The third uncle squinted his eyes. He thought about Xu Zhiyi, whom he had captured from the northwest.

I know that Ma Laoliu is quite keen on researching zombie vaccines.

Even before, in the research laboratory of Wuyuan Mountain, they created a wall-climbing zombie that was not afraid of ultraviolet light.

Later, when Xu Zhiyi passed by Wuyuan Mountain and headed to the north, he killed the wall-climbing zombie that was not afraid of ultraviolet light and warned Ma Laoliu.

In addition, Ma Laoliu previously learned that Oil City has the ability to control zombies.

They sent people to the trading market and agreed to cooperate with Oil City. Their core purpose was to obtain the zombie antidote from Oil City.

Zombie antidote is not very realistic.

It is also possible that a zombie vaccine can prevent people from being bitten by zombies and turning into zombies.

But the third uncle didn't even dare to think of a zombie antidote that could turn zombies back into humans.

In order to win Ma Laoliu's trust, the third uncle agreed to them and made a promise that as long as Ma Laoliu could obtain the meteorites from the northwest, Oil City would be able to develop a zombie antidote for him.

After all, the extraterrestrial meteorite was still too difficult to deal with. Ma Laoliu had no idea how to deal with it, so he just let it go.

In this way, combined with everything before, the third uncle almost concluded that the artificially injected liquid must be related to Ma Laoliu.

But...why would he do this?

Experiment?

But isn’t this kind of experiment afraid of causing backlash?

If they want to do experiments, just do experiments. They don't do it in the laboratory, but do it in the open air city, and there are so many experimental zombies at one time, what are they doing...

The third uncle had many doubts at this time and couldn't figure it out for a while.

But the judge and the others have brought back the potion and mutated zombies, and they will be sent to the zombie research institute at the headquarters base for research.

After the judge's report, the third uncle also came back to his senses.

"Okay, I get it. It doesn't matter if you can't find it. Just find a safe shelter on the way. You can return tomorrow if you're not in a hurry."

"Okay, got it." The judge took off the radio headset and turned his head to look at the mutant zombies at the back of the cabin. Those zombies were all tied up and fixed, making them relatively stable.

He looked away, put on the walkie-talkie headset again, and glanced at his watch. It was already half past three.

The distance from BY City to Oil City is nearly 1,400 kilometers, and it takes at least 5 hours to fly back by helicopter.

Five hours. If we didn't find shelter and returned directly, it would be half past eight by the time they arrived.

Now the clouds are accumulating and the earth is dark, making it more dangerous than before.

At least there was a moon and starlight in the past.

Although the helicopter has strong lights, if it encounters a tall hillside while flying rapidly and is unable to raise the altitude in time, it is likely to cause the aircraft to crash and kill people.

Flying a helicopter at night is extremely dangerous.

The judge naturally didn't want to take risks, so he pressed the intercom and said to everyone:

"It's too late. We'll find a suitable shelter on the way back later and return to Oil City early tomorrow morning."

"receive."

"receive."

"receive."

........

Two hours later, they arrived at SL City, southeast of West City.

As a big city in the west, West City has an extremely large number of zombies in the apocalypse.

The number of zombies in Shangluo, dozens of kilometers away from the West Market, is relatively small.

They landed on the top floor of a large shopping mall in the center of SL City.

This kind of rooftop is perfect for parking a helicopter overnight.

This chapter is not over yet, please click on the next page to continue reading the exciting content! Park a helicopter on the ground in the suburbs or countryside, and zombies may come from all directions at night.

Although there are a lot of zombies in the city, they are parked on the top floors of shopping malls. The only threats to them are wall-climbing zombies.

They only need to seal the corridor leading to the top floor and turn on the ultraviolet light, and they can sit back and relax.

It's already getting dark.

After the two helicopters docked, the ultraviolet lights on the helicopters were not turned off.

Lao Qin and Jackal got off the helicopter with ultraviolet lights and ran to seal the top floor door.

The ants and nuts went to the other side.

As for He Feng, Ma Dong, Black Hand, Zheng Shiwu and the judge, they quickly arranged the ultraviolet lights they brought around the helicopter.

There is no room on the roof of this building, so they can only sleep in the helicopter for one night.

Soon, after they closed the stair passage, Lao Qin and others returned to the helicopter.

Around the helicopter, the judge and others have arranged ultraviolet lights.

A circle of ultraviolet lights is connected to the socket, and the light is facing outside. With such dense light, it will be no problem even if there are more wall-climbing zombies.

After doing all this, the judge said to Lao Qin:

"Old Qin, go check on the captured zombies and don't run out."

"I'll go with you." Zheng Shiwu raised his hand and said.

The judge nodded to him. This Zheng Shiwu was not bad. He was able to keep up with their pace today and was much better than that black hand.

The two entered the helicopter to check whether the ropes binding the zombies were stable.

On the other side, Hefeng and Ma Dong did not stop and added the last bit of fuel carried by the helicopter into the tank.

...

The night is dark and windy.
