The whole city is my old attack

"Just guessing."

Chu Feng clicked on the light screen, covering the 7-year-old Xiao Xie's crazy combat power on the screen.

"Yes, yes!" The system elf supported his master, "Using wrong guesses as the premise of reasoning will only lead to wrong illusions, by Sherlock Holmes. Let's look for other clues!"

Lin Lan: "...Did Holmes say that?"

"Go up and have a look." Chu Feng pointed to the fourth floor.

They have almost checked the clues on the third floor.

Main clues: ①The cat hair that fell; ②The blood stains on the wall covered by green paint.

Inference: The cat died in the corridor on the third floor.

Further speculation: the uncle in the commissary in room 304 raised a cat, and the cat was killed by the unemployed cat abuser in room 402 at the door of his house.

Chu Feng was walking on the stairs to the fourth floor, thinking in his heart, these two are the most direct evidences at present, and they can only be explored to this point, and there is no way to reason about other things.They need to find more clues on the fourth floor.

"You move the character out of this building first." Chu Feng said to the elf.

The system + points obediently moved the 7-year-old Xiaoxie who hugged the cat and Xiaoxie who caught the spider to a safe place. The 7-year-old observation swallow Xiaoxie has been infected with the virus and has been isolated temporarily.

Da da da.

Chu Feng, Lin Lan, and X walked towards the fourth floor. As usual, X started and Chu Feng was last.The system elf flew next to the little master, and the searchlight was lighted up on the hair:

"Be careful, the floors above the 4th floor are all abnormal floors infected by the virus!"

X entered the darkness first, followed by Lin Lan.As soon as Chu Feng stepped in, a gust of cold wind blew the silk scarf around his neck, and the thin shirt in midsummer couldn't resist the chill of the wind.

"It's so strange..." Lin Lan muttered, "The corridor here has no windows, how could there be wind..."

pat.

In the darkness, there was a light ahead, and X turned on the light in the corridor on the fourth floor.

The light cord was deliberately cut very short, and the end of the cord was glued to the upper left of the wall with transparent glue, far above the position where ordinary people can reach out, just because they don't want people to turn on the light and waste electricity.People who have just come to this building, if they don't look carefully on the wall, it is impossible to know where the light cord is stuck.

But in the complete darkness, X once again found the position of the light rope.

"Smooth again?" Chu Feng raised his eyebrows and looked at X:

X: "..."

"Strange, why are there no swallows?" said the system elf, flying around the four corners of the top of the corridor wall.

Chu Feng raised his eyes and looked at the wall. The above 4th floor of the residential building was infected by the virus. Either the virus was brought by swallows, or the 7-year-old Xiao Xie was the virus itself.Just in case, they have to make double preparations, while solving the puzzle of 7-year-old Xiao Xie, while controlling the swallows that may be carrying the virus.

Chu Feng remembered that there was a swallow's nest in front of Xiaoyu's house, and he had visited it when he was a child.But now the walls are empty, there are faint mud and stains where some swallows built their nests, but there are no nests, and no young swallows are seen.

"Did someone... get rid of it?" Lin Lan asked. He had seen the news that when the health city was selected, some districts would smash all the bird's nests everywhere, otherwise the birds would shit every day in the corridors. , dripping on the wall and the ground, it is a mess, which affects the perception.

Chu Feng frowned. He vaguely remembered that Xiao Xie had complained to him before, and the gossip aunt of 402 was particularly hateful.Originally, his house already had a swallow's nest, and the two swallows worked hard to build the nest and hatched the eggs.Xiao Xie's mother was also very happy. It is a symbol of good luck for the swallows to build a nest at the door of the house.Xiao Xie was also very happy, and even made an appointment with Xiao Chu Feng, and invited him to come and see the swallow when the little chick swallow hatched.

In the end, the aunt of 402 didn't know what she was doing that day, so she called a wall painter to paint the wall, and deliberately painted it on Xiao Xie's house, stabbing his house's swallow's nest.

The newborn baby swallows fell out of the nest and fell to the ground, killing them one by one, leaving blood all over the door of Xiaoxie's house.

"This aunt...don't let it go!" Lin Lan looked at the wall:

"She didn't paint the walls of Brother Xie's house either. There were swallows' sludge all over the wall, so she deliberately found an excuse to poke the swallow's nest at the door of someone else's house. There were still live birds in that nest. Is the aunt abnormal? ?”

The system dropped out of the building list just now: "I don't think there are normal people in this building."

Lin Lan: "...that's exactly what you said."

X: "Auntie asked someone to paint the wall?"

Chu Feng also immediately thought of the half green wall on the third floor that covered the bloodstains.

Lin Lan: "Then... Could it be that my aunt asked someone to brush it?"

A cat hair, a little blood on the third floor, and now three people are connected in series.

The cat probably belonged to the uncle in the commissary in room 304. The unemployed man in room 402 killed the cat, and the blood splashed on the wall. Then the lady in room 401 sent someone to paint the wall on the third floor.

The system calls out [Security Question]: "In this way, there are still 403-drunk and 504-Schrödinger residents in the original question. I don't know what role these two people play."

"Go in and have a look." Standing at the door of Room 404, Chu Feng took out a steel key from his backpack. The tip of the cross-shaped key was aligned with the door opening.

The door of Xiao Yu's house is a green iron door, and there are many black rust spots on the door.The copper-yellow doorknob was stained with rust, and there was a cross-shaped keyhole in the middle.

The upper part of the green iron sheets is hollowed out, with a few iron pillars inserted, like the iron bars of a prison.Through the cracks in the railings, I can see that the second door inside is a brown wooden door with a small peephole on it.

No matter how many times Chu Feng sees this door, he still feels... a little unsafe.The iron railing above the first green iron door is not very dense, and the hand can be stretched in through the door lever of the first green iron door. With a little tool, the door lock can be pulled directly from the inside.No need to pry open the door.

——In this way, only the second protection is left, but the second is a wooden door. Compared with iron doors, wooden doors are much more fragile. If an adult man is stronger, he can just kick open and break in.

squeak-

open the door.

Lin Lan walked in. Brother Xie lived in a very small place when he was a child.Although he knew that Brother Xie's family was not well off, Lin Lan was still a little shocked when he suddenly saw that Brother Xie, who grew up driving a Lamborghini and owned a lot of big villas, lived in such a place when he was a child.

The whole house is no more than 40 square meters. It looks like it has been cleaned up deliberately, but it is still a mess.There is no way to put so many things in such a small space.There were even drug needles in the trash can.

Chu Feng frowned. He remembered that after restoring his memory, he cleaned up all these messy things.I bought some cute toys and high-end furniture for Xiao Xie, and tidied up the small room very warmly.

But now that the virus invaded, those appearances decorated by Chu Feng were shattered, and the room faded into its original appearance.

Soot, drug needles, a paper bag on the table with a pinch of white powder inside, an unwashed pot, a stove covered with black butter stains, rotten leftovers, wet clothes that have not been exposed to sunlight, Yellow, yellow and green, hanging by the window.The whole house is noisy.

The house of less than 40 square meters was divided into two rooms.Entering the door and turning left is the place where Xiaoyu lives, and walking straight through the door is his parents' site. ——There is no living room, the living room is just a big bed, connected to the kitchen, dining table, toilet, and window, which is barely his parents' room.

There is no balcony in such a small house, only one window, the glass is dark blue, a clothesline is tied to the window, and some washed pajamas and pajamas are drying, some are torn, and they are still patched. ,wear.One piece of clothing stretched out its arms and legs, hanging on the clothesline like a hanged ghost.

"He and I will look this way." Chu Feng pulled Lin Lan into Xiaoyu's room.

It was here that X grabbed the two little Xies just now. He had already seen Xiao Xie's room, so he turned around and went to the "living room" - his parents' territory to look for clues.

After 22 years, Chu Feng walked into Xiao Yu's room again. It looked much more normal than the living room. At least there were no drug needles in the trash can.

"Will brother Xie hide things under the bed?"

Lin Lan looked behind the door, behind the cabinet, and then lay down on the floor to check under the bed. He remembered that when he was a child, he often hid comic books under the bed. Children would definitely think of these hidden places when hiding things.

Chu Feng didn't squat down to look. As far as he knew, Xie Shiyu was not very good at hiding things according to ordinary people's thinking.For example, in the graffiti book I found last time, there were wine bottles drawn and ticked off. That book recorded the killing of those four people by 24-year-old Xie Shiyu, but Xie Shiyu generously put this graffiti book in the study room. In the drawer, not guilty at all.

Xie Shiyu knows how to hide things, but he deliberately puts things outside, pretending to be normal objects.

Chu Feng looked at the cabinet that Xiao Yu placed on the bright side. There were some old dinosaur toys on it.It may be a second-hand toy that others don't want, but Xiao Xie's mother picked it up for him.

Chu Feng bought a lot of novelty toys such as remote control cars, remote control planes, and electric dinosaurs from the Dream City mall for Xiao Yu to play with, but now those novelty toys have disappeared, and this cabinet has returned to its appearance 22 years ago. .

Holding a flashlight, Chu Feng rummaged through the cabinet, and soon found a book with a dinosaur pattern.

He remembered that this was the first day of the first grade of elementary school. The school teacher issued a notebook for each student in the class. The girls were kittens and the boys were dinosaurs.

The little green dinosaur on the notebook looked at Chu Feng with wide eyes, and there was a big thorn on its neck.

Chu Feng opened the dinosaur book, and it was full of graffiti.

Chu Feng read a few pages and found that this was Xiao Yu's diary 22 years ago!Xiao Yu, a first-grade student, doesn't know how to write too much, so the diary is his doodle book.

He immediately thought of 24-year-old Xie Shiyu's graffiti book, a very simple wine glass, and ticked it to indicate that it was completed.

——This kind of symbols and note-taking habits should be developed from an early age.

Chu Feng immediately rummaged through the diary for the tick mark.

Soon, Chu Feng found a page. On the diary was a schematic drawing of the building. Two windows were drawn on each floor, and the house numbers were written on the windows.

Next to the schematic diagram of this building, Xiao Yu ticked 5 ticks!
