About the matter of Mrs. Chen's superstition in science

"Reiko-san, please sit down, can I drink tea? There is also milk at home."

"Tea is fine."

Now that the weather is getting colder, the palm of my hand is burning hot when I press it on the pottery cup, and soon it turns slightly red.

Reiko took a sip, and looked around secretly by lowering her head. She was not interested in the decoration, but cared about the ubiquitous rotten smell, like the corpses of cats and dogs thrown in the corner and slowly decomposing.

"Can I see the rooms upstairs?"

Upstairs is a relatively private place. It should have been an abrupt request, but Reiko's expression was very frank. She didn't feel guilty about prying into the owner's privacy at all. It was so natural that she just wanted to borrow the toilet.

Wakaca was surprised and didn't refuse. After Reiko put down the tea cup, she led her upstairs, and introduced her one by one as she passed the rooms, "This is the guest room, which is usually cleaned. If Reiko-san wants to be a guest, she can stay overnight at any time; It is my self-satisfied study, where I have collected many books; over there is the bathroom..."

Reiko suddenly stopped in front of a door, Wakana only hesitated for a moment before unscrewing the door kick, "This is a laboratory, I usually do some experiments here."

"experiment?"

Zhengchou and young people have nothing in common. Thinking of Tanjiro's surprise when he used the microscope for the first time, Wakana thought that Reiko, who was about the same age, would also be interested. Do you want to try?"

Reiko walked over, did not sit down, but paid some attention to the things placed beside her.

It was a black gun. Reiko didn't have a deep understanding of guns. As a layman, she felt that this style was very strange. There was a wrench without a magazine, was it a toy?It can shoot flowers or parachutes.

If it's just a toy, there's no need to put it on the experimental table. Thinking of Wakana's research, Reiko made a bold guess.

Wakana narrated eloquently, her gentle tone could not conceal her joy, "This is a machine that can emit ultraviolet rays. If it can be mass-produced, Tanjiro and the others will not have to risk their lives to fight ghosts. By the way, Reiko-san, you You don’t know about ghosts, do you? Ghosts are different from monsters, their staple food is humans.”

Reiko-sang nodded, "Well, I know, the sun, which is the ghost's weakness, you ultraviolet rays... What ghosts are afraid of is not the sun, but the ultraviolet rays in the sun?"

"It's just a trial work, and it needs to be adjusted after actual combat data collection." After finishing speaking, Wakana picked up a test tube next to it, "This is the wisteria flower poison I extracted. Tanjiro said that wisteria flowers are also the weakness of ghosts, but I have never understood the principle without a test subject."

Reiko leaned down and took a closer look. The test tube contained white powder, which should have been specially processed, very fine and without any smell, and would be regarded as ordinary flour.

"It's amazing, you can still do this." Reiko turned her attention back to the ultraviolet emitter while speaking. At first glance, the operation is very simple, and any fool can use the button. "Can I try it?"

Wakaca hurriedly put her hand on the back of her hand, changed the direction of the gun, and stopped softly, "Appropriate exposure to ultraviolet rays is beneficial to the human body, but excessive absorption can easily induce skin cancer. The emission level has not been adjusted yet, so be careful not to point at yourself ,in case."

Reiko was just curious for a while, she didn't mean to make fun of her body, so she put the ultraviolet emitter back to the original place, and turned to look at another place, and felt an invisible black mist coming out of the door through the door. Drilling into the flesh and blood, the dark fear in the bottom of the heart is constantly being born.

Reiko tentatively probed, "There is actually a small door in the laboratory, do you still need a rest room at home?"

"Sorry, you can't go in there, that's my husband's laboratory." After speaking, Wakana felt ashamed to reject others, fearing that Reiko might misunderstand her and suspect that she was suspected of stealing business secrets, she quickly explained, "It's not that I don't trust Reiko. San, it's just that he's sensitive to the smell of strangers."

Reiko was noncommittal, but this trip allowed her to confirm the fact that the "Tsukihiko" Wakana was talking about was not a human being. She and Lushen were only suspicious before, but now she can be sure that the other party is a ghost. Ghosts who do not clear their sins.

Reiko learned more or less about the Demon Slayer Squad from Wakana's mouth. It is impossible for professionals not to see Tsukihiko's abnormality. If they haven't done anything yet, they can think that it is not an easy target to kill.

She thought a lot in her head, but the reality was only for a moment. Reiko didn't show any anxiety or worry in her heart.

Jingle Bell.

Hearing the ringing of the phone, Wakana smiled apologetically at Reiko, "It may be Tsukihiko calling, he is always worried that I am alone at home."

When Wakana turned around and walked away, Reiko put away all her expressions, and her lips were tightly pressed into a straight line. When she said that the call was from Tsukihiko, Wakana's face was full of joy and happiness that she didn't even notice.

This is very difficult.

It wasn't Yue Yan who opened the phone, and Wakana was still very happy to hear the angry voice on the other side, "Why would you think of calling me at this time?"

Of course my wife and father heard the "Yueyan" that my daughter was expecting when he first answered the phone, and pretended to be dissatisfied and said, "Is Yueyan only allowed to call you? It is really the water thrown by the married daughter. When playing shogi, let's see how I can kill him without leaving any pieces."

Wakana just smiled and said nothing, in fact, the two of them played shogi and my wife and father had never beaten Tsukihiko.

The father and daughter said a few more homely things, and only got down to business when they learned that Wakaca was fine.

"I'm going to drink tea with the old man later. You're bored at home by yourself. Come with me. By the way, I'll meet someone. They adopted a child. You haven't seen it yet. It's about the same age as Kajiang. Junguo, like you, likes reading very much, he is a very smart kid."

Speaking of this, my wife and father snorted dissatisfiedly, "Yue Yan is really true, my wife doesn't know how to ask for maternity leave to go home to accompany her when she has a big belly. All day long is work, and the money can be earned ?"

Wakaca has no reason not to agree, and she hasn't visited the Sakata couple for a while, but she feels the need to explain the complaint about the second half of the sentence, "Yue Yan is also under a lot of pressure recently, and it costs a lot of money to buy a new house."

Of course my wife's father knew about this, he was not short of money, but his daughter didn't accept it, but Yueyan was very helpful because of his daughter's willingness to move, so he couldn't help but praise him a few words.

Hanging up the phone, I was about to tell Reiko that she was going out soon, but when I returned to the laboratory, I found that no one was there. I searched the whole house and found no one. "...Is there something urgent?"

This worry did not dissipate until my wife's big house, afraid that my wife and father would misunderstand, so I had to cheer up, entered the house, and was told by the housekeeper that my father was packing things in the attic, Wakana said in surprise, "Why did you suddenly think of packing the old things? "

"It should be because I saw the photo of Master Junguo and thought of the things about Miss when she was a child. The way Master Junguo sat quietly reading a book really looked like Miss. Back then, Miss was only this little old." The housekeeper lovingly compared with his hands At the same height, eyes full of nostalgia, "When I was the most mischievous, I always ran around with the young master, and I couldn't calm down. Only when I read a book can I calm down. I just sit for a long time."

handsome country.

Wakaca remembered that this was the name of the child adopted by the Sakata couple.

How can Wakana remember such a long childhood? According to the housekeeper's description, she can't bring herself to jump up and down, but it is true that she likes to read books. The world in the book is very exciting.

"What you said made me a little curious about this kid, Junguo. Okay, you can be busy. I'll go and see my father first."

There are many old things stored in the pavilion, and the maids usually come up to clean them up. Except for some miscellaneous things, every corner is clean, without the smell of mold and dust.Walking around a single-door cabinet, Ruo Cai saw my wife and father squatting in front of a wooden box, holding something in their hands and looking intently.

Looking around, Wakaca picked up some old low stools and put them behind my wife and father, "Squat like this and be careful that you won't be able to straighten your back later."

My wife and father, who heard the movement early in the morning, were not frightened by the sudden sound, so they sat down on the stool and waved back without looking back, "It's just in time, let's see what this is?"

Wakaca could hear an uncontrollable smile from his voice, and walked over suspiciously to have a look. In addition to a few photo albums, there were thick leather books stacked in two rows in the box, and the time was written on the spine in turn.

Wakana blushed, "How can you peek at my diary!"

Ever since she knew how to read and write, Wakana had the habit of writing a diary. After marrying Tsukihiko, she didn't know why she didn't write any more. After thinking about it carefully, she couldn't figure out why.

My wife and father coughed guiltyly, "I only watched the first year's film, and didn't watch anything else."

Probably knowing that I was wrong, my wife and father ran downstairs holding the photo album.

Wakaca can't laugh or cry, it doesn't matter whether it's private or not, it's all diaries from childhood, it's just that the naive thoughts of childhood will feel ashamed.

Pull out the first book in order, open it, there are just a few lines of writing on it, each stroke is very rough, there is no structure at all, it writes all kinds of trivial things that seem to be worth mentioning today, the same as the little friend's Ordinary bickering can be regarded as the sky is falling.

In the sixth book, I have just graduated from school, at an upright and green age, it is all about the delicate and sensitive thoughts of a girl.

While looking back, he missed his youthful days, and suddenly changed his style of painting.

July [-]th

the truth of the world

With a few numbers, each stroke penetrates the back of the paper, as deep as it is branded on the soul.

Wakana doesn't have any relevant memories of writing this line of text.

Turn to the previous page, the date is May [-]th, what happened in between?No, she clearly remembered that she should be studying abroad at this time.

Continue to look down, the subsequent diary is very fragmented, there is no regular record every day, often after ten days and a half months, and the content is also inexplicable, if Wakasa did not recognize that these are indeed her own notes, she would have suspected that someone else was pretending to be that's it.

"..."

Covering her face, Wakana thought hard, racking her brains to recall the events of this year.

No.

No.

No.

No matter how I think about it, I can’t remember it, and even the memory of studying abroad is blurred and becomes extremely unreal.

The lavender smeared on the pupils suddenly deepened.

The problematic... maybe her memory.
