It's a lot more interesting than a cat and a mouse.

Yin Xiyue was like a little overseer, watching Master Xia's work through the screen of her mobile phone without blinking.

Xia Yanfei memorized the position of the strap on the waist bag and put it aside for the time being.

Putting the old phone on the sofa, he sat directly on the floor for ease of movement.

Anyway, the school uniform on my body will be washed tonight, and the floor has been wiped by myself in the morning, so I don't have to worry about what to do if it gets dirty.

It's better to say that while blowing the cold wind of the air conditioner, sitting on the slightly cool floor makes Xia Yanfei, who is sweating outside, very comfortable.

I just have to hurry up and take a shower in a while.

After washing and eating, no, you will sweat again when you cook the noodles, so let's eat first.

Sighing slightly, he continued his work.

On the other hand, the girl on the screen, her delicate skin as white as milk shines with clear water, and the comfortable home T-shirt still has water stains left by undried water.

This clean-loving girl must have taken a shower as soon as she got home.

That's right.

Xia Yanfei thought about it in confusion.

She walked twice as fast as usual, why did this girl go home earlier than herself?

She had finished her shower, and she had only been on her feet for a few minutes.

"Don't worry about it, I'll fly back."

Yin Xiyue seemed to know his thoughts well, but it was better to say that Xia Yanfei couldn't hide her emotions in front of her at all.

"THIS ABILITY IS TOO BUGGY...... But I like it."

After complimenting, Xia Yanfei touched the screen of the video call with his finger as an affirmation of this girl.

"Hehe, you can guess why I'm in a hurry to fly back tonight."

Yin Xiyue smiled proudly, turned her head and threw him a question.

"I really don't know this, is it to see cats and mice?"

"That's one of the reasons, but most importantly, you didn't say it."

"Seek a decryption."

"Ahem, it's actually because the potato chips say that they taste best within 24 hours after opening the bag."

「……」

"Okay, okay, I'll admit that I asked you this question on purpose, please don't look at me with the eyes of a child."

Yin Xiyue blushed a little, and she clasped her hands together while biting a piece of potato chips in her mouth, and said obediently.

Xia Yanfei smiled bitterly and returned to the matter at hand, and the girl also brushed back to normal, as if she had forgotten some failed pranks just now in the blink of an eye.

Now the main problem is the operation of the old phone, he thought about it.

Unlike humans, who can take out their mobile phones anytime and anywhere for a variety of swipe and click operations, it is difficult for big cats and Shiba Inu to take it out neatly, and in the end they still have to rely on their mouths to hold it.

If you want them to control their phones, you need to find a flat place to put them.

This is possible, but it is inconvenient.

Xia Yanfei would not use such a clumsy method, if these two guys broke the phone, the gain would outweigh the loss.

In addition to various professional tools, there is also a part of the basic materials in the toolbox.

Although it is not possible to borrow a lathe for on-site machining here, it is possible to assemble these things with uniform specifications.

The current problem is that the big cat can be unlocked and operated normally without taking out the mobile phone on its back.

"Come to think of it, this place should be nice with hydraulic cables."

Xia Yanfei said to himself, and now he is completely serious.

Take out a few pieces of stainless steel material to prepare as a mobile phone case, and then take out a small bundle of hydraulic cables and the liquid dish structure at the end.

The cat had jumped back on the couch and was leaning comfortably on the Shiba Inu's belly, curious about his movements and the parts he didn't recognize.

Because of Xia Yanfei's love for his bike, he knows the structure of the bike very well.

The handbrake is also a very important part, because it is related to the safety of life in an emergency, and it has always been careful and serious.

There are also quite a few bicycle parts at home.

Although he had the idea of changing to a bicycle, this old friend is still comfortable and reliable, so it seems that Xia Yanfei may be a little nostalgic.

He rode it to this day.

The handbrake of the bicycle is connected to the liquid disc structure through the hydraulic line, and the piston on the liquid disc can be controlled to do telescopic movement by giving a stretching signal, and it can be dialed in four or two.

For the problem at hand, the retractable piston is just right to complete the task of pressing the phone.

Thinking of a rough plan, Xia Yanfei first had to use these stainless steel sheets to form a metal mobile phone case.

It will act as an external frame and perform the task of fixing the parts and aligning the position.

These stainless steel sheets have holes in them, and they can be spliced tightly by inserting short screws and nuts.

After that, put the old phone in it, put foam paper on the corners of the contact, and confirm that the installation is the next step.

The phone can still be used to accomplish different tasks with a combination of the power button and the volume button.

In order to protect their eyesight, Xia Yanfei decided that they could only touch their mobile phones under their own supervision.

And when he's not around, just give the unlock, call and photo functions to do it.

What kind of mobile phone do you play with when you go out, isn't it good to take pictures of the scenery?

Xia Yanfei explained to the big flower cat and the Shiba Inu, and they readily agreed, it would be good to go to him at noon.

Yin Xiyue originally wanted to help him, but the obedience of these two guys was beyond her expectations.

She and the technician Master Xia glanced at each other quite tacitly.

He set up his phone, put himself as the only contact in the quick call, and then canceled the password, which was unlocked by pressing the power on.

It is then bound to the action of the key.

Finally, align the liquid dish structure with these buttons and fix it again with screws.

Of course, there were no suitable holes on the stainless steel sheet, so Xia Yanfei took a hand drill and directly drilled a few new ones, and the position was quite accurate.

After a whole set of actions, the end result is a bizarre mobile phone case, pulling a long hydraulic cable and a delicate device fixed to it.

"Okay, finally plug in my old headphones, and add another control device to the headphones."

Xia Yanfei patted the crumbs on his hands and picked up the black earphones on the ground.

It's not big, it's small, otherwise they wouldn't be able to wear it.

The transmission structure of the bicycle handbrake is dismantled and fixed firmly, and connected to the hydraulic cable.

Then put the headphone cable *** old mobile phone into the incomparably advanced 3.5 headphone jack, and the whole work is done.

"It's going well, nothing went wrong, cat, let's try it."

He put the phone into the Xia Yanfei brand phone case, then put it in his waist bag, and adjusted the position to let the camera peek out through the gap in the zipper.

"Look, this elastic lever, yes, that's where your claws touch, no, don't touch it just yet. Long press to call me, short press to answer, short press twice to take a picture."

Xia Yanfei chattered, put the waist bag around the fat belly, and put the earphones on the ears of the big cat.
