On the weekend of the next day, Tan Jiacheng went to work overtime.

There is only one nanny at home who takes care of Tan Qingyao and Jiang Ru, who is in a ghost state.

Tan Qingyao noticed that the water heater was boiling water when she was washing her face, and she couldn't restrain her little hands that wanted to dismantle things.

Because Tan Qingyao is very easy to bring, she usually only needs to feed at a fixed time.

So the nanny and aunt were playing with their mobile phones in the living room, and they didn't see Tan Qingyao dismantling the water heater at all.

And Jiang Ru, who could see Tan Qingyao dismantling the water heater, couldn't stop it.

To be right, she wouldn't stop it either.

Not only will he not stop it, but he also cheered Tan Qingyao on the side, teaching her how to use a screwdriver and how to unscrew the screws.

Otherwise, since Tan Qingyao has never dismantled things, he is likely to demolish it violently at the beginning.

Of course, it is not excluded that she is smarter, and she knows how to use it at a glance.

"Yaoyao, you are so powerful, you dismantled the shell so quickly." Jiang Ru praised.

[Host, are you sure this is really good?] This is a high-IQ talent, won't you take her badly? 】

[Eleven, you are also a high-tech system, how can you still have such an idea? Children should improve their hands-on ability to better develop their brains. 】

[But host, are you sure you want your little girl to dismantle the water heater?] 】

[Why not?] Jiang Ru raised her eyebrows, [I have already taught her to turn off the electricity and gas, why can't she dismantle it? 】

[Host, it's good if you're happy.] Eleven sighed.

[Eleven, I find that you are becoming more and more like a human being, and you still have this gender bias. Why can't girls dismantle things? 】

Jiang Ru pondered, the system is a product of high technology, even if there is life, but at most it is only mechanical life, why do the current ideas tend to human thoughts?

However, Jiang Ru thought about it and felt that it was wrong, in so many worlds, it was impossible for all human beings to be weak women.

So, the biggest possibility is that the system was generated by the world I'm in?

Before Jiang Ru had time to think deeply, she heard Tan Qingyao say, "Mom, what is this?" ”

Jiang Ru came back to her senses, looked at it twice, and found that she didn't know it either, so she said, "Mom doesn't know you either, why don't you check it on the Internet?" ”

Tan Qingyao nodded, and ran to the study to check things with Tan Jiacheng's computer.

The nanny saw her run out, but she just glanced at it twice, didn't pay much attention, and continued to play with her mobile phone.

Tan Qingyao's relationship with the nanny is average, so she won't say hello to the nanny or anything like that.

Entering the study, Tan Qingyao went straight to the computer.

She occasionally uses this computer to watch online classes, so she knows the password of the computer, and when she comes in, she climbs directly into the chair in front of the desk and turns on the computer.

Without Jiang Rujiao, Tan Qingyao knew how to check, so she clicked on the search software and started searching.

Not only does it not have to teach Tan Qingyao to search for information, Tan Qingyao has also learned to use the knowledge network without a teacher!

She looked at some scattered information on the Internet and felt that it was not enough, so she used her mobile phone to register an account on the knowledge network, and then directly searched for professional information.

"Yaoyao, do you want to look at the most basic first?" Jiang Ru proposed.

She felt a little big for an adult to read this complicated material, let alone a child.

However, she underestimated Tan Qingyao's IQ.

She actually understood!

He also said with a puzzled face: "Mom, this is very basic." ”

Well? Very basic?

Jiang Ru's face was full of question marks.

Is this jargon book basic?

It's just about the structure of a water heater, why is it so complicated? I also wrote dozens of pages of books!

[Host, this book is indeed very basic, you can know it by looking at the name.] 】

Jiang Ru glanced at the title of the book.

The basic working principle and basic structure of gas water heaters. 》

Jiang Ru's face was expressionless.

Oh! The name is quite "basic", but I lost.

I'm probably a centuries-old antique, and I can't keep up with the times.

Jiang Ru sat on the side and watched Tan Qingyao read the book in ten lines.

"Yaoyao, do you understand?"

Although Jiang Ru asked so, seeing her confident appearance, her heart was already sure.

She already got it!

Sure enough, in the next second, Tan Qingyao said calmly: "I'm almost done, but I still have to give it a try to know the specific effect." ”

In the living room, the nanny looked at the time, and it was already noon.

She had just been cooking and was just chatting with people, and since she had forgotten to cook.

Thinking of the employer's daughter, the concept of time is very important, and she must eat regularly, otherwise she will definitely sue the employer.

The babysitter decided to make noodles.

Tan Qingyao passed by the living room without squinting, entered his room, climbed on the stool next to the water heater, and carefully studied the structure of the water heater, like a staff member designing a water heater.

At half past twelve, Tan Qingyao's stomach rumbled on time.

She touched her belly, looked at the water heater that had only been half dismantled, and fell into deep thought.

Am I going to eat first, or am I going to tear it down first?

"Yaoyao! Eat first! Your body is important! Gotta eat first! Jiang Ru sensed her thoughts and immediately spoke.

Tan Qingyao regretfully put down the screwdriver and wrench in her hand, and then turned on the faucet to prepare to wash her hands.

But no water came out of the faucet.

She couldn't help but drag her chin with her hand and carefully observe the open faucet.

What's going on? Why is there no water coming out? Did I break it down?

But I'm dismantling the water heater, so the faucet shouldn't be broken here.

Besides, I also dismantled it according to the steps, and it is impossible to affect the faucet!

Suddenly, many possibilities flashed through her mind.

At this moment, Jiang Ru had seen enough of her distressed little face, and finally spoke.

"Yaoyao, didn't you open the sluice?"

"Sluice?" Tan Qingyao was obviously stunned for a moment, before remembering, "Yes, I just closed the sluice, if it is not opened, there will definitely be no water here." ”

She suddenly felt that there was something magical about the sluice, since she was able to control all the water.

"Mom, what is the principle of this sluice? Why is there no water on the faucet when the sluice gate is closed? ”

Jiang Ru thought for a moment and said, "All the water pipes are connected to the main water pipe here, and if you turn the sluice gate on the main water pipe, there will be something blocking the water pipe." In this way, the water in the main water pipe cannot flow through. ”

"Is it like that?" Tan Qingyao drew a schematic diagram with Jiang Ru in three clicks and two clicks.

Jiang Ru looked at the schematic diagram and thought: I have finally found one of Tan Qingyao's weaknesses again. The picture is fundamentally Picasso-style.

Abstract! The average person can't understand it!

But it's much easier to know what it is and then push it back.

"Yes." Jiang Ru nodded, feeling guilty.

"Mom is amazing! Actually know this! Tan Qingyao praised.

"Don't look at whose mother it is!" Jiang Ru accepted the praise very humbly.
