Kyungwon was glad that he had sealed the wall of the villa area, otherwise those zombies who didn't know where they would have squeezed into the wall and walked around the door of his house, making a rancid disgusting smell everywhere.

It took him a lot of effort to clean up the zombies in the villa area, but he didn't want to do it again, he hated the feeling of rotting blood splashing on his clothes and body.

In the attic, Tang Xue was still using a telescope to observe the world outside the wall.

She carried a lamp and sat on a chair, turning the direction of the telescope from time to time.

It was already 9 o'clock at night, and Kyungwon climbed the ladder to the attic with a thermos cup hanging from his waist.

"Drink some hot water, I just boiled it." He put the cup on the small table and sat down beside Tang Xue.

"Thank you." Tang Xue took the thermos cup, unscrewed the lid, poured a cup of hot water into it, and put it aside to dry.

"How's it going?" Kyungwon asked.

"It's more than that." Tang Xue handed over a notebook, and she used it to record the situation.

Jing Yuan opened the book and read it, there were three pages in total, and each page was dotted with a black pen.

"These three pages are the density map of the distribution of living corpses at 10 a.m., 4 p.m. and 8 p.m. this morning, and one dot represents a living corpse." Tang Xue explained.

Jing Yuan opened the book and looked at it, and he could clearly see that the number of zombies had increased by almost half of the total number after three pages, and these numbers had increased in 10 hours, a visible increase to the naked eye.

"Looking out of the attic, I can only see the living corpses near the south, I roughly counted, in the morning, there were a total of 26 zombies wandering around where I could see, and now it is 38, of course, this number is not very accurate, because they have been moving around, and the zombies in this vicinity have been replaced."

Tang Xue pressed the spring of the ballpoint pen and took out an old newspaper.

"What is this?" Kyungwon took the newspaper.

As of the year before the disaster, the total number of households in Zhoushan City was 154101, the registered population was 422231, most of the population was in the city center, and the total resident population in the southern suburbs was 100,000 according to a quarter, but it certainly could not reach the number of 100,000, and the permanent population here should be between 10,000 and 20,000 households, and the total number would not exceed 50,000." Tang Xue said.

"What is this?" Kyungwon saw the calculation formula she had written in the blank space of the newspaper.

"Based on this data, combined with the number of surrounding villages, the size of the apartments and the year-end financial report of the water and electricity company, I estimated the density of the population, and subtracted this number by half, which is about the density of living corpses." Tang Xue said.

"Where did you get all this data?" Jing Yuan looked at those dense numbers and felt a headache.

"Newspapers, magazines, and some data I've read before, so I've written it down, and I have a good memory." Tang Xue said lightly.

"And what did you do the math?" Kyungwon asked.

"Zhoushan City has jurisdiction over two streets, 10 towns, 1 township, our location, is Shanjing Street, the final calculation result, the population distribution density here, about 24 people per square kilometer, minus half is the distribution density of living corpses."

"That's 12 zombies per square kilometer, compared to the estimated number, what is the actual observed density, have you calculated?"

"The actual observed density is 13 per square kilometer, and because they've been moving around, it's on the high side, but it's already over the estimated average density, which means that almost all of the living corpses that were supposed to be indoors, or somewhere else, are moving around, and for some reason we don't know, they're becoming extremely active."

"Is that so" Kyungwon glanced out the window, and there were still many zombies wandering in the dark night.

In fact, he has been observing the map today, and the mutated creatures scattered everywhere, in addition to the elite monsters, some have also moved, moving irregularly, and some monster icons have disappeared.

The silent city of Zhoushan seems to have come alive with the arrival of spring.

"Mr. Kyungwon, I want to move the telescope to the roof." Tang Xue suddenly interrupted Jing Yuan's thoughts.

"Rooftop?" Jing Yuan came back to his senses: "Why, do you think the vision here is not wide enough?" ”

"Yes, although there are two windows in the attic, there are still some blind spots that you can't see."

"No, I don't agree." Kyungwon shook his head: "The attic is at least indoors, if you sit on the roof, there will be nothing to cover you, and if there is a flying creature like a mutant weaver, it will be very dangerous." ”

"But weren't those birds burned by a fire?"

"That's right, but I'm not sure if there will be similar zombie birds in other places in Zhoushan City, they may fly over, I told you, I can sense the distribution of some monsters, and even the actions of those monsters have become strange, you just stay in the room, don't go out."

When Jing Yuan explained to Tang Xue the ability to manipulate the flora, he mentioned this matter, but only briefly mentioned it, saying that he could roughly sense the position and movement of other mutants.

"yes. I see, so I'll stay in the attic and observe. Tang Xue nodded.

"That's it for today, let's get up tomorrow morning and watch."

Kyungwon stood up, withdrew the head of the telescope, closed the window, pulled down the steel plate, and only the lamp in the small attic lit up with a white light, illuminating the faces of the two.

"It's time to rest, the walls are thick, the iron gates are thick, they can't break in."

"Hmm." Tang Xue picked up the cup of water that was about the same as it was to dry, and drank it all.

The two of them went downstairs together, and after washing, they lay on the bed in the bedroom, and Xiaobai was already lying on his stomach in the kennel.

When the lights are turned off, the bedroom becomes a black box, and the steel plates seal all the windows, so that not even a ray of moonlight can penetrate it.

"I'm a little scared."

"Afraid of what?"

"I'm afraid we won't be able to live like this anymore."

"If something unexpected happens, we'll drive away and head further north, where it snows all year round, and we'll be safe."

"Well, I'll go wherever you go."

"Don't worry, this is not the city center, I have already cleaned up the mutants around here, and it is impossible for those zombies to break in."

"Actually, I've always wanted to ask, Mr. Kyungmoto, how far away can you perceive monsters?"

"How far. The entire state mountain can feel it. ”

"Is it clear?"

"It should be pretty clear."

"It's amazing."

"So-so."

"No, I think you're underestimating yourself, you're really powerful, much more powerful than you think, much more special."
