Fuyunoso is partly a monolithic module made of a mixture of steel, wood, and concrete, but as a whole, it is still a mortise and tenon rivet structure and a concrete tile roof.

The construction cost of traditional buildings is much smaller than that of earthquake-resistant buildings with "reinforced concrete metamorphosis reinforcement", and the space is sufficient, and the courtyard can also complement each other, but the disadvantage is that it needs to be maintained with a lot of effort and money.

"Here, here, here, and here......" Yuuki quickly drew circles on the roof.

Asuka looked at it in a daze, is Youyijun doing this mark? It's only been four months, how can there be so many bad things?

This is the house...... It's not a cardboard box house for children.

It can't be the last supplier who cheated her on the quality of building materials, right?

However, inspecting the roof is a time-consuming and laborious task...... Could it be that Yuichi doesn't like this job, so he wants to deal with things so hastily?

……

Over there, Yuuki Yuuki enclosed all the "discordant" places, and there were eleven of them...... It's really time for repairs.

The pale blue border in his eyes disappeared, and his vision returned to normal, and he exhaled slightly, shaking his slightly heavy brain, and then squatted down and began to check.

He bent his fingers and tapped on it, there was no abnormal hollow sound, and there was enough hardness.

"What's wrong?" He was a little puzzled.

Looking to the side, I could clearly see the difference between the old and the new concrete tiles.

"An old tile......" He pondered for a moment, looked up at Asuka, and asked in a loud voice, "Sister Asuka, what will happen to the tiles of the roof in general?" ”

"See if the tiles have been weathered, if they have separated from the clay underneath, or if they have become less permeable."

"Clay separation?" He nodded thoughtfully, but instead of breaking it immediately, he stood up and walked over and said, "Please bring me a jug of water!" ”

"Take it!" The love below is already prepared.

Yuuki mentioned the kettle, but did not go over immediately, but humbly asked: "What do you think of this water permeability?" ”

Asuka squatted down and pointed to a piece of tile, saying, "If the tile is weathered, the windproof and waterproof properties will deteriorate, and after being washed away by the rain, the bottom will be separated from the clay...... If you pour water on it, if there is a water stain on the back, it means that there is something wrong with the tile. ”

"I see!" Yuki Yu is clear, then as long as you see the movement of the break, it is good, of course, there may be less clay paste, but the tile is no problem, so in order to reduce the "manslaughter", it is still necessary to do a water permeability test in advance.

He walked over with a kettle, walked to the tile he was squatting on, and poured a small half pot of water directly on it.

After waiting for a few minutes, he tried to break the tiles, and then he actually broke them for him.

Yuuki raised his eyebrows and turned the tiles over, seeing obvious water stains behind them.

He nodded, found the crux of the problem, and felt at ease, raised it and waved, "The tiles here are broken!" ”

Asuka had confirmed that it was a weathered tile after he had broken it off, but she couldn't help but be surprised.

Youyi-kun's luck is good! Circle a random place just to really circle him with a problem.

"I see!" She answered, and asked Ainai to fetch new tiles and clay.

That's what she's doing here.

Yuuki Yuki broke around in a mess, broke off all the problematic tiles, and walked over with his arms.

Asuka took a closer look and praised: "It's all old tiles, it's amazing, Yuyi-kun!" ”

Yuki Yu smiled, then crouched in front of the first circle of the drawing, and with the experience just now, it was much easier.

There are no other problems, almost all of them are weathered tiles.

When he finished breaking it, there were more than 20 pieces.

Asuka looked at this piece with a lot of light in her eyes: "It's really a big catch!" Now you can rest assured for a while! How did Youyijun find out this? ”

"Rely on eyesight to ......" Yuuki said the truth that was not a truth.

"By sight?" Asuka looked strange, and then looked at the rows of concrete tiles by herself, and looked at them for a long time, but she didn't see why.

She said thoughtfully: "You Yijun's eyesight is really good. ”

At this time, Aino below shouted, "Then can you see the youkai?" ”

"Youkai?" He was stunned for a moment and wondered, "Are there any monsters in this world?" ”

"Where's the youkai?" Asuka said angrily, looked down and said, "Hurry up!" Don't talk nonsense! ”

"It's good if there are no youkai......" Yuuki Yuuki's face softened.

He's an outsider, or the kind of "borrowing corpses to resurrect souls", and I'm really not sure if there are any monsters in this world......

I hope it's just an absurd story!

Seeing his serious expression, Asuka couldn't help but laugh and said, "Aina, this girl usually likes to read those stories, and she is a little affected, so don't worry about her"

Yuuki Yuichi looked dumbfounded, took the mud basin and tools in her hand, and walked over with the new tiles.

Asuka followed behind, and taught him how to do it carelessly: "Shovel off the ones below, and the new clay should be smoothed evenly, pay attention not too much, and try to keep the same thickness as other places......"

Yuki Yuichi focused on his mind and used the calculation power of the [Arithmetic], and he suddenly raised his head: "2% error is no problem, right?" ”

Asuka was dumbfounded: "How can it be so accurate, we are not professionals!" Do it with your eyes and senses! Sister believes in you! ”

"Good!" Yuuki shoveled off the clay underneath little by little, looked around carefully, and smeared new clay on the bottom little by little as he calculated.

The small more than 20 tiles actually took him nearly three hours.

While he was laying the tiles, Asuka was also checking other places, and after three hours, she checked all the key places, and she really didn't find any extra bad ones.

She looked at Yuuki Yuichi with a strange expression, could it be that Yuichi-kun really did this just by her eyes?

It used to take a whole day to inspect the roof, but this morning it was done.

Amazing!
