North of the Han River, Changhanping Qingchun Community.

On the roof of a residential building, black smoke rose to the dark and gray sky.

Next to the iron basin lit by black smoke, a girl sat on her knees, her delicate eyebrows and eyes, revealing deep fatigue.

The difficult survival experience of the past few days has already exhausted her physically and mentally.

Even if the black smoke stained her cheeks, she didn't bother to wipe them clean.

She continued to pick up the plastic bottle at her feet and carefully placed it in the iron basin to make the fireworks burn more vigorously.

The black smoke is the last hope.

She was waiting for rescue, a rescue that would stake the lives of everyone present.

Gathered around the bonfire were a grandmother in a wheelchair, two little boys, and two black bags.

They were also apprehensive, looking into the distance, hoping for a miracle.

One of the little boys, biting his fingers, asked timidly.

"Sister Shuli, will there really be a helicopter to pick us up?"

Shu Li, who was exhausted, showed a firm smile.

"I believe my sister, there will be a helicopter to pick us up."

In fact, it doesn't matter whether you believe it or not.

Because this is their last hope to live.

Food is basically depleted, physical condition is getting worse and worse, there is a lack of critical medical supplies, and the number of zombies outside is increasing unabated.

Together with the survivors who fled earlier, they took some of the food with them, and the rest of the food could not last more than a day or two.

A group of them, young and old, are weak and weak, and they are simply unable to withstand the pressure of zombies and collect enough supplies to survive.

Fortunately, at the last extreme moment, Sheriff Zheng agreed to her and helped contact the Seoul City Hall to carry out rescue.

In order to cooperate with Sheriff Zheng's action, Shu Li also lit fireworks on the rooftop, hoping to attract the attention of the rescue smoothly so as not to miss the last chance.

"Boom"

The walkie-talkie next to Shu Li came out with an intermittent murmur.

She quickly picked up the walkie-talkie and put it to her ear to listen carefully.

"Doctor Shu, this is Sheriff Zheng."

"I've been able to get in touch with the City Hall Shelter."

"Three minutes from now, they'll have a helicopter passing by your apartment."

"The rescue team is in a very urgent situation, and it is necessary to send a conspicuous distress signal in time to avoid missing the rescue opportunity!"

Shu Li finally waited for the good news, and couldn't help covering her mouth, unable to hide the joy in her heart.

After Sheriff Zheng finished speaking, she pressed the call button again.

"Sheriff Zheng is very grateful for your help."

"We lit a fire on the rooftop, and the black smoke was a prominent reminder to the helicopter rescue team."

"Thank you!!"

End the call.

The old grandmother in a wheelchair cried with joy and wiped the old tears from the corners of her eyes.

"Good grandson, the helicopter will be coming to pick us up soon."

The little boy, who was originally weak, raised his eyes to the sky more seriously, revealing a yearning look.

"Boom"

Suddenly, a rolling thunderclap, accompanied by lightning, resounded through the sky.

The thunder shook the crowd.

Shu Li hurriedly looked up,

Is it going to rain? She couldn't help but look nervous.

If it rains at this juncture, once the brazier is wet, the black smoke will break.

The helicopters passing by three minutes later are likely not to be able to detect them, resulting in a complete miss of the final rescue.

Don't let the campfire get wet!

Shu Li hurriedly looked around, looking for a place or tool that could shelter from the rain.

The roof was empty, with no shelter.

The most convenient wooden plank for shelter from the rain is covered at the entrance and exit of the rooftop, preventing zombies from detecting that there are living people on the rooftop.

The entrance and exit is an iron gate, in disrepair and rusty.

Slightly caused the movement of zombies in the corridor, the iron gate could not withstand the impact of zombies at all, and it was impossible to use wooden planks to shelter from the rain.

At this moment, above the roof, a large dark cloud covered the roof, so heavy that it was about to fall down.

Thundered.

Thunder rolled, and a loud sound woke up the zombies in the building.

They began to move slowly, roaming and wandering.

As the thunder intensified, they became more and more agitated.

The hallway began to hear the sound of footsteps and the rude roar of 'ho-ho-ho'.

Shu Li was so anxious that she glanced at the sky in the distance, but still didn't see the shadow of rescue.

If this continues, if a zombie accidentally breaks into the rooftop, everyone will die.

The fire must be protected against the wooden plank at the door.

She took off her white tracksuit, handed it to the two boys, and admonished him earnestly.

"If it rains, you must cover the brazier from the rain to prevent it from going out, remember?"

The little boys nodded earnestly, grabbed the corners of their coats, and spread them out against the braziers.

In order to strengthen the rainproof effect, Shu Li picked up a few more plastic bags, tore them and spread them on her clothes.

After finishing this, she took a small basin to catch the rainwater, and in turn put a plastic bag on it, and held it above her grandmother's head.

Finally, I picked up the walkie-talkie, ran to the entrance and exit of the rooftop, and pressed my body against the wooden board.

"Boom"

There was another rolling thunder, which shook people's scalps.

Shu Li could clearly hear the chaotic footsteps of zombies behind the door panel, getting closer and closer.

Startled by the thunder, they scurried around the house, gradually approaching the rooftop.

She gritted her silver teeth, trying to calm herself.

"Calm down. Calm down and hold on for the last three minutes. ”

But the sky doesn't follow people's wishes.

Tick.

The first drop of rain fell from the clouds and hit Shu Li's forehead, leaving a circle of coldness.

She raised her head and looked at the big beads and small beads flying in the sky, densely packed, and all of them fell down in an instant.

"Bang la la"

A sudden rainstorm caught them off guard.

Almost instantly, the cold rain drenched her heart.

But she didn't care about herself at all, but looked at the little boys worriedly.

They were also surrounded by the torrential rain, like two young lone seedlings in a storm, trembling and supporting, clutching the coats in their hands.

The brazier under his coat is still trying to burn.

The black oil made from the burned plastic was stained on the bottom of the basin, emitting wisps of black smoke, rising against the rain and drifting into the sky.

However, the rain curtain was too urgent, blocking the view, and the visibility range was reduced.

They couldn't see the helicopter, and it was hard for the helicopter to notice them on the rooftop.

At this time, the door panel that Shu Li was holding against suddenly moved.

It's like a zombie accidentally knocked on the door, found that it couldn't be opened, and turned away.

Fortunately, the force of the door is not large.

"Bang!"

The door panel was hit again, and more and more zombies wandered to the rooftop corridor.

Shu Li hurriedly opened her arms, and the whole person leaned back, stubbornly against the door panel.

Now is the most critical moment of rescue, as long as the door panel is loosened a little, all the previous efforts are wasted.

Suddenly.

Shu Li felt a whirlwind blowing towards her face, and the rain that flew diagonally hit her face and hurt.

The whirling wind and rain of the helicopter propellers made a whooshing roar.

She braved the icy rain and struggled to look into the center of the whirlwind.

A red helicopter, hovering not far above the rooftop, was flashing blue-green signal lights.

Hope is coming!

She looked excited, expecting the helicopter to arrive.

But the helicopter kept hovering in the air, without the slightest intention of continuing to descend, as if it was looking for a distress signal.

A distress signal?!

Black smoke! The black smoke is gone!

At this time, she saw the little boy on the left, staggering and weak.

They have never eaten enough, but they have persevered until now, and they have completely become the end of the crossbow.

Under the blow of the storm, the little boy finally failed to hold on, and fell to the ground, unconscious.

Another little boy hurriedly threw himself on top of the brazier, trying to protect the only remaining flames with his small body.

But it was too late.

Boom. The rain instantly extinguished the pot fire, extinguished the black smoke, and poured cold water on the fire of hope in the hearts of everyone present.

Shu Li could only watch everything happen, but there was nothing she could do.

At this time, the old woman rolled her wheelchair and came to her side.

Then he turned the direction of the wheelchair, pressed the back of the chair against the door panel, and pulled the handbrake.

"Little girl, leave this door panel to me, try one last time."

Shu Li's pupils shrank suddenly, looking at the old grandmother's cloudy but kind eyebrows, not knowing what to say.

Holding back the emotions that swelled in her heart, she left the door panel behind her and ran wildly to the edge of the rooftop, picking up the clothes on the floor.

Standing at the top of the edge of the rooftop, he kept waving his blackened white coat in his hand, trying to get the attention of the helicopter.

But under the cover of the downpour, it seems that the world is dyed gray.

The helicopter plane circled for a while and began to slowly rise in altitude.

Shu Li saw with her own eyes that the last rescue was about to leave, and she couldn't wait to jump over to attract the attention of the helicopter.

Seeing the whistling of the propellers, it gradually faded away.

The zombie behind him was about to break through the wooden door and run to the rooftop.

The desperation at one end of the scale began to tilt more and more.

"Bang!"

A gunshot, comparable to a thunderbolt, echoed in the silent rain curtain.

Gunshots?!

Shu Li was stunned.

"Bang!"

Another startling gunshot, it sounded like it was coming from downstairs.

The gunfire was extremely penetrating, and immediately attracted a large number of zombies, who rushed towards the source of the sound and gave up entering the rooftop.

Then a thick white mist drifted up from downstairs, choking his mouth and nose.

Thick smoke billowed up against the rain and drifted into the sky.

Shu Li choked on tears, still trying her best to wave the white coat in her hand.

Finally, the helicopter returned again, slowly landing in their direction.

Shu Li cried with joy.

At this moment, she clenched the walkie-talkie in her hand and had a clear understanding.

Long after the helicopter left, the dark clouds gradually dispersed, and a rainbow hung over the ruined city for the first time in a long time.

A man in an army-green raincoat came to the rooftop where Shu Li had stayed just now.

The rooftop was occupied by a crowd of corpses, empty.

The wooden planks that blocked the doorway toppled to the ground, and the extinguished brazier was flooded with rainwater, leaving some torn plastic bags around.

"It seems that Dr. Shu and the others have successfully evacuated."

Zheng Xun walked to the two black bags and looked at them, the bags were bigger than the snakeskin bags.

The bag was bulging, like it contained something big, heavy.

He unzipped the bag, revealing a young girl lying inside.

The girl is white-skinned and beautiful, and it is very well preserved.

The thin summer silk shirt on his body was soaked by the rain, revealing a light blue hue of underwear.

Her cute and playful eyelashes are stained with raindrops, as if she has just fallen into a deep sleep, curled up in a clump of mermaids.

He then opened another bag, which also contained a young girl curled up in the same shape as the girl next to her.

"I didn't expect it to be you."

"Twins."

"Ann Yoo-ni, Ann Yo-yeon."

Before Zheng Xun came to the rooftop, he first went to the house of the twin girl group to see it.

It was a mess inside, and there wasn't a single figure.

Rummaged around the room and almost everything was arranged in pairs.

From toothpaste, toothbrushes, cups, to hoods, bottoms, and underwear.

Looking at the work schedule of the twin trainees, he rested at home on the day of the zombie outbreak.

From this, it can be seen that they are either torn and mutated by zombies, or they are with a nearby team of survivors.

Reminiscent of what Dr. Shu said, a pair of twins suffering from acute gastroenteritis are most likely An Yuni and An Yunyan.

Zheng Xun squatted down, pinched the pretty face of the beauty with his left and right hands, and calculated the new scientific exploration experiment plan in his heart.

"Doctor Shu can't save you."

"Maybe I can."

"That's the greatness of scientists."

There's a big chapter a little later, and I'm coding words.
