Xing Hechou walked into the house and closed the door with his hand.

The interior of the mansion still maintains the same scene as when Leon and the others first entered, with the lights in the living room on, a few pairs of shoes in the entryway, and all doors and windows kept closed.

The interior furnishings that were messed up by the player's rummaging cabinets before have all returned to their original positions, and there is no trace of being turned over.

The deathly silence slowly settled, and only the sound of Xing He's boots stomping on the ground seemed to be left in the room.

"Strange..."

Leon's voice sounded in his head.

"Huh?" Xing Hechou asked, "Did you find anything?" ”

"It's so stuffy in the house."

Leon replied, "On the way here, we confirmed that it was about 6 p.m. on the 11th day of May in the first year of Reiwa, and on the Saturday of Toyo Day, through the calendar wall calendars sold at convenience stores and electronic clocks.

Assuming this is a real-world mapping, the weather on Hishima should be muggy at this time of 2019.

Other people in the same alley as Fukujin's house, either the air conditioner outside is turning, or the doors and windows are open,

Only Fukujin's house has doors and windows closed, and the air conditioner is not moving.

It doesn't matter if it's the first time or the second time we enter the house, it's like this.

The open state of the shops and houses along the way is enough to prove that the alleys and alleys at this moment are not typhoon weather, and there is no need to close the doors and windows. ”

Xing Hechou felt it carefully, and indeed felt that the room was a little stuffy,

Before he kicked open the door to ventilate the room,

Now that the door is closed, it feels a little stuffy inside.

"Isn't that normal?"

Wanli Fengdao was puzzled: "Maybe the Fushen family went out to run errands or took advantage of Saturday to play?" ”

"Unlikely."

Leon said, "Pay attention to the shoes in the entrance.

On the left side of the entrance is a three-story old wooden shoe cabinet that is almost full, and on the right is a bamboo umbrella barrel with three-color floor tiles and a circle of smooth stones on the edge of the floor tiles.

There are two rows of shoes placed on the side near the entrance, most of which are shoes of adult men or middle-aged and elderly men and women, and the tips of the shoes are facing the door, which is commonly used in daily life.

It should be the shoes used by the family's great-grandmother Fukujin Miyoko, the parents Fukujin Hirahara and his wife, and the youngest son Fukujin Hiroji.

And away from the side of the entrance, is a pair of women's high heels and children's shoes.

It is likely that the eldest daughter of the family, the married Emon Kyoko, and the great-granddaughter Emon Shion are wearing shoes. ”

Wanli Fengdao was even more puzzled: "Wait, what does the placement of shoes in the entrance have to do with their family going out to play?" ”

Liu Wuxian said: "The so-called entrance is the earliest word used in Zen Taoism.

This concept was introduced into ancient East Asian architecture, where it became an intimate space that separated the inside and outside of the house.

Traditional Chinese architecture uses screens, doors or chairs as partitions.

And Hijima sinks the entrance, imitating the meaning of Zen-style platform, as a partition.

The Japanese-style entrance can be used to keep out moisture and dust, and guests are required to take off their coats and hats when they visit, and then enter the entrance after getting dressed, and when taking off their shoes, they need to place their shoes with the tips facing the door and facing one side.

Since Emon's shoes are placed on the left side, and since they don't often live in this house, it can be assumed that Emon Kyoko brought her daughter to visit her parents, grandmother, and younger brother.

And her shoes are still in the hallway,

That is, she did not leave the house. ”

"Uh..."

Xing He was stunned for a few seconds, thought about it carefully, and asked: "Is it possible, it is that Emon Kyoko often takes her daughter back to her parents' house, and it is inconvenient to change shoes every time she goes in and out.

Fukujin Plains and his wife specially prepared spare shoes for their daughter and granddaughter at the entrance? ”

"Unlikely."

"The first two rows of shoes are often used by the resident family members of this mansion, and even if the Fukujin Plains couple wants to prepare spare shoes for their daughter and granddaughter, they should also be placed in the shoe cabinet, or close to the side of the entrance.

In this way, it will not get in the way in normal times. ”

Liu Wuxian added: "Moreover, the entrance area of the Fushen family is small, and there is no stool for people to sit on.

In other words, the family may usually sit in the hallway and change their shoes.

And the pair of children's shoes worn by the eight-year-old girl Emon Shion were placed on the outermost side away from the entrance - with the length of a little girl, it was not enough for her to sit on the entrance and change the shoes directly.

That would definitely step on someone else's shoes.

This is even more proof that Kyoko Emon and her daughter are only visiting temporarily and have not left yet. ”

“...”

Xing Hechou nodded silently, "Okay, this is indeed strange. When my daughter came to visit, the doors and windows were closed and the air conditioner was not turned on. ”

"There's something even weirder,"

Li Ang said, "Brother Xing, please go to the living room and take a look at the window there." ”

"Okay."

Xing Hechou didn't talk nonsense, he left the entrance directly and walked into the living room, opening the closed window, "Is there anything wrong with this window?" ”

"Note that this is a casement window, the window frame is made of plastic steel, there are rubber strips around it, and the glass used for the window is double-layer hollow laminated glass," Leon said. ”

Xing Hechou frowned and said, "Laminated glass? ”

Leon said: "Well, pay attention to the other houses in this alley, all of which use single-glazed sliding windows that were installed uniformly when they were built.

Only Fushen's house uses double-layer hollow laminated glass and casement windows made of plastic steel.

The sound insulation of the window depends on the tightness of the whole window,

Due to the rubber stickers, the casement window has better sound insulation than the sliding window.

Since the four corners of the plastic steel are bonded together with hot melt, it is better than the aluminum alloy that is put together.

The double-layer hollow laminated glass is two layers of glass glued together.

In appearance, it is almost the same as ordinary single-sided glass, but the sound and heat insulation effect is much stronger.

In other words, the windows used in Fukujin's house are special soundproof windows customized by themselves.

Isn't it strange to use special soundproof windows in such a remote and deserted alley?

After all, the courtyards of the neighbors' houses are all sunning in their home clothes, and they don't look like wandering musicians who like to play rock and make noise. ”

“...”

Xing Hechou took a deep breath, "Brother Li, where did you learn all this knowledge?"

Don't tell me you're still a renovation enthusiast. ”

"Haha, I understand a little, I just understand a little."

Li Ang laughed,

Only Miss Chai, who is hiding in his body, knows why he understands decoration - Li Ang carried out a series of soundproofing modifications to the room behind the landlady's back a long time ago, and it can't be seen from the outside, but the soundproofing effect is so strong that it is off the charts.

Even if you sing KTV in the house, you won't be disturbed by neighbors' complaints.

God knows what Leon wants such a strong sound insulation effect for....
