In Room 2901 of Building 19, Lu Yu, Xiao Ran, and Xu Xiaoxiao were sitting around the dining table.

The dishes and chopsticks on the table have long been cleaned up, replaced by a white sheet of A3 paper, on which a simple map of the neighborhood and its surroundings is drawn.

Lu Yu and Xiao Ran were frowning and staring at the map on the table, constantly discussing something, the pencil in their hands kept writing on the paper, but after a few seconds, they crossed it out again. And Xu Xiaoxiao looked at the two of them nervously, not daring to make a sound.

"There are only two options!" Xiao Ran seemed to be in a depressed mood, and kept poking the pencil in his hand onto the paper, and the pointed graphite pen tip was quickly poked flat, leaving one ugly hole after another on the paper.

"It's really ......" Lu Yu looked at the words on the paper that had not been crossed out, and stretched.

"What are the two options?" Xu Xiaoxiao, who had been staying aside and didn't dare to speak, saw that the two had finally finished discussing, so he curiously approached Xiao Ran's side.

Now she has understood that her previous good deeds are likely to have caused a catastrophe, and as the initiator of this incident, her current attitude is simply low to the dust, and she looks like a schoolgirl who has made a mistake and wants to work hard to make up for it.

"First: we leave with limited water and food. Second: We wait in this room for each other to come to the door. Xiao Ran casually discarded the pencil in his hand on the table, with his hands on his cheeks, looking preoccupied.

"If we leave with food, we won't be able to take much with us, not to mention that there are so many zombies outside, and if we can't keep it, we will be attacked......" Xu Xiaoxiao muttered to himself.

"You know it's dangerous to leave, huh?" Lu Yu said angrily, if it weren't for the overly kind-hearted girl in front of her who sent food out recklessly, the news that her family had abundant reserves and a small number of people would not have leaked out so early, let alone scratch her head and think about how to deal with the next situation.

"What happens if you stay at home and wait for the other person to come to the door?" Xu Xiaoxiao was choked by Lu Yu, his face turned red, and he said hesitantly.

"If you stay at home and wait for someone to come to your door, there are two possibilities. The first type: the opponent is more numerous than us, and has the strength to overwhelm us, and may have better and more lethal weapons than we have, and the three of us will be directly suppressed, or even killed. Xiao Ran paused and glanced at the modified crossbow on the sofa.

"The second possibility is that the other side is about the same number as us, and the weapons and equipment are also equal to us, and for the sake of food, the other side may offer to cooperate with us and share the food."

When Xu Xiaoxiao heard this, his eyes lit up, and he hurriedly interjected, "Then if it's the second possibility, wouldn't it be good if we refused to cooperate, anyway, we have a lot of food, we have the initiative, it's a big deal to fight a protracted war with them." ”

"If we live in a well-guarded fortress, it is a good way to fight for a long time, but we only live in a civilian house, do you think the gate of Uncle Lu Yu's house can be strong enough to resist the destruction of brute force? If we refuse to cooperate with the other party and refuse to share food, then the other party, when there is a shortage of food and water, and at the same time they dare not go outside to collect supplies, will inevitably break into the net with us and break into the door with violence, and at that time, our safety will still be threatened. ”

"Is it possible that the number of people on the other side is less than ours......" Xu Xiaoxiao seemed to think of something, but swallowed back the words halfway through, as if she herself felt that this possibility was relatively slim.

"The possibility of fewer people than us is very small, since the other party can send a man to step on the point, then it means that the number of people on the other side is at least more than two, and the other party can have the consciousness to come to explore us, it means that we may have supplies, I think it should be when we came back from collecting materials from the supermarket two days ago, we were targeted." Xiao Ran didn't care about Xu Xiaoxiao's embarrassment, and still analyzed it in detail, and exchanged glances with Lu Yu at the same time.

"Okay, you can't be blamed for this, if it weren't for me and Xiao Ran being targeted when we came back from collecting supplies two days ago, they wouldn't have sent someone to step on the door, and the reason why I didn't open the door and wanted to drive that person away at the beginning was because I was afraid of exposing our actual number of people and the number of materials."

"That is to say, if I didn't open the door and rush out at the beginning, the person who stepped on the spot wouldn't know exactly how many people we had here, and wouldn't dare to act rashly, and we wouldn't have to ......divide the food for no reason," Xu Xiaoxiao muttered to himself, finally realizing how stupid his kindness was before.

"The point is that we don't know the location of the other party's stronghold now, but we roughly know that in the area of Building 7, there is no way to take the initiative to ambush, so we can only wait for the other party to come to the door."

A hint of killing intent flashed in Lu Yu's eyes, it was not that he didn't want to annihilate the other party, but the information he had in his hands was really limited, and a rash ambush would only increase the risk.

"I can only wait for the other party to come to the door, and pray that they are about the same number as us, otherwise we will really have to evacuate with some supplies." Looking at the neatly stacked food in the house, in the last days, sufficient water and food are the most important survival materials, and the thought of these things about to be shared by others made Xiao Ran's heart feel a pain in his heart.

Just when the three of them were sad and at a loss, a muffled sound of a heavy object falling to the ground came from the ceiling, and the three of them looked towards the place where the sound came from. At that moment, a shadow scurried through the kitchen window and flew towards the distant sky.

"What's that?" Lu Yu was the first to get up, looking out of the kitchen window, and faintly seemed to be able to see a huge bird creature with black and white feathers flying into the distance, with an unimaginably fast speed.

"Is it a mutant creature again...... Lu Yu was shocked in his heart, he had seen an orange cat the size of a leopard before, a corn cannon that could fire itself, a huge gourd that could breathe in the supermarket, and now he had seen a giant bird that flew extremely fast, this phenomenon couldn't help but confirm the guess in his heart - not only human beings were affected by this catastrophe, but almost all animals and plants should have undergone great changes due to this catastrophe.

"My mom, what's that? How could there be such a big bird......" Xu Xiaoxiao exclaimed, she had already heard about Lu Yu and Xiao Ran's experience of going to the supermarket to collect supplies, and she had a preliminary understanding of the fact that there were already mutant creatures in the post-cataclysmic world, but seeing the huge birds passing in front of her, the huge spiritual impact still made her open her mouth wide, and she was stunned in place and didn't dare to move.

Unlike Lu Yu and Xu Xiaoxiao, after Xiao Ran saw the giant bird passing away outside the window for the first time, his eyes did not stay there too long, but focused his attention on the place where the muffled sound came from before.

The sound came from the ceiling, and Lu Yu's family lived on the top floor, that is, the source of the sound was caused by the heavy object falling on the rooftop!

Xiao Ran's mind was thinking quickly, and he walked quickly to the sofa and grabbed the modified crossbow on it.

"We'll have to go to the rooftop." Xiao Ran skillfully filled the modified crossbow with crossbow arrows, and shouted at Lu Yu and Xu Xiaoxiao who were standing at the window.

"Rooftop?" Lu Yu and Xu Xiaoxiao recovered from the shock of seeing the giant bird, and then remembered that when the giant bird flew over, there was a muffled sound coming from overhead.

"Okay, I'll get ready." Lu Yu immediately understood what Xiao Ran meant, picked up the hard hat on the ground, and began to arm himself.

"I can help too!" Seeing that Lu Yu and Xiao Ran looked like they were going out to help, Xu Xiaoxiao hurriedly raised his hand and shouted.

After all, Lu Yu had told her before that he would let her "work" to pay off the food she owed.

"...... you" Lu Yu glanced at Xu Xiaoxiao up and down, the girl's figure still hasn't changed much, and there is one word on her body - strong!

"Maybe this girl with a hole in her head can really help......" Lu Yu thought in his heart, but nodded without the slightest expression on his face.

"It's okay for you to come along, follow the command, and pay attention to safety. Also, put this down jacket on. ”

Lu Yu briefly explained to Xu Xiaoxiao, grabbed a black men's down jacket and threw it to the girl in front of him.

"Why do you wear a down jacket? It's May, isn't it cold? The girl looked at the thick clothes in her hand, and her face was full of doubts and puzzles.

"Just put it on, don't push it too much." Lu Yu returned to his previous appearance of Lu Peeling, urging impatiently, and at the same time glanced at Xu Xiaoxiao's long bare legs.

Xu Xiaoxiao was wearing a T-shirt and hot pants when he came, and he didn't change it during the time he came to Lu Yu's house.

"The long legs of the muscular girl are really attractive." Lu Yu silently deserted in his heart and walked towards the bedroom.

As if sensing Lu Yu's gaze, and as if he was frightened by Lu Yu's appearance of Lu Yu's skin, Xu Xiaoxiao immediately put on a down jacket and covered his strong figure.

When Lu Yu came out of the bedroom, he already had a pair of thick jeans, a thick scarf and a pair of gloves in his hand, and threw them in front of Xu Xiaoxiao.

"Put it all on, cover everything you can, and don't leave your skin exposed." After speaking, he stopped looking at Xu Xiaoxiao, and turned around to check his metal baseball bat.

After a while, the three of them were ready, with Lu Yu taking the lead, Xiao Ran standing in the middle, and Xu Xiaoxiao standing at the end, and walked out of the gate in turn.

Since Lu Yu's family lives on the top floor, the access to the rooftop only needs to go up from the fire escape.

Carefully pushing open the fire door on the rooftop, Lu Yu quietly poked his head out of the crack in the door and looked around.

The rooftop was silent, and there seemed to be no sign of zombies or other creatures.

"I'll go out and have a look first, you help me guard the door, and if anything is wrong, answer me at the door." Lu Yu whispered a few words to the two, and walked towards the rooftop.

Xiao Ran and Xu Xiaoxiao watched nervously as Lu Yu moved slowly, constantly observing the situation around them.

The sun hung high overhead, and the brightness on the rooftop was a little dazzling, but for Lu Yu, such a good visual environment was very beneficial to his own safety.

I saw Lu Yu step by step, exploring the surrounding corners little by little, his movements were cautious and slow, it seemed that as long as there was a slight movement, he would pull his legs and run.

But after checking around, Lu Yu found that the rooftop was surprisingly quiet, and there were no zombies or strange creatures roaming on it.

I breathed a sigh of relief in my heart, the only place I hadn't checked now was the back of the water tank in front of me, Lu Yu knew that that location corresponded to his own living room, and the strange response that came from before should have come from behind that water tank.

Thinking of this, Lu Yu's heart couldn't help but start beating violently, and the nervous emotions drove the secretion of adrenaline, making his breathing start to be a little short.

At this time, if someone stood beside Lu Yu, they could clearly observe that on Lu Yu's neck, which was not covered by a scarf, dense black blood vessels faintly appeared, and those blood vessels seemed to be alive, as Lu Yu's heartbeat continued to extend, slowly climbing up Lu Yu's chin.

But the focused Lu Yu didn't notice the changes in his body at all, just moved his feet slowly, moving forward little by little.

Soon, a human leg appeared in Lu Yu's field of vision......
