"It's not called a black cat, it can change color, it can change orange, it can change white, you can make her whatever color it is."

The proprietress smiled, thinking that this little girl was still too naïve, everyone who knew the goods knew that any robot system could be ever-changing, and this little girl was probably the first time to buy a robot system.

Looking at the little girl's dress, she doesn't look like a rich person, she is estimated to be a child from an under-middle-class family.

"Little girl, do you need to help you pack the courier home?"

The proprietress said, putting the plastic bag of the other robot system back in so that the robot system would not be contaminated with some dust.

"No, no, I can take it back, I don't need to help me pack it, I'm going to use it when I go out."

Bei Yinan shook her head and said, what is the courier for, she doesn't even know who she is, she doesn't even know where her home is, and she can't express it.

"Then I'll help you turn it on, by the way, this navigation robot system, it's the energy core of the solar panel, when it's here, it's here, and when the color here changes from green, to yellow, and then to red, you have to charge it."

The proprietress enthusiastically helped North Yinan, this girl didn't know anything, as a person who bought the product, she should give the little girl a popularization of how to use.

"There are two ways to recover the energy of the navigation robot system, one is direct charging, and the other is solar charging, which can be directly exposed to the sun." The proprietress handed over the navigation robot system to Bei Yinan and taught Bei Yinan hand in hand to see if she could teach her to use the navigation robot.

"What's the difference between the two charging methods?" North and South are interested in solar charging, which is environmentally friendly, saves money, and reduces the expenditure of Star Coins.

"The former charges quickly, which is the cost of electricity, and the latter charges slowly, but it is free."

"Thank you, sister." Bei Yinan nodded in understanding and thanked the proprietress for that.

"Don't call me sister, I'm in my thirties and forties, just call me aunt."

The proprietress smiled and looked at Bei Yinan, this little girl just loves to listen, I didn't expect that she was so young and beautiful.

"Well, thank you, Auntie."

"Of course, you can also use this navigation robot system during the day and on a sunny day to store energy values at the same time."

The proprietress reminded the north and the south to try this method, which is the most economical method at present, which can reduce a lot of unnecessary trouble.

"Here's the trunk mat, which stores energy values, and this is called back-up hidden energy." The proprietress introduced, "This is the open button, when you don't want to use it, when you want to turn it off, you can directly talk to the navigation robot system after opening." ”

"The navigation robot system can hear what you say clearly, can understand what you mean, and its thinking logic is loaded according to people."

"Understood."

"Thank you."

Bei Yinan clicked the start button, and soon, the cat in his hand moved, it opened its eyes, and got up from its hand, and the energy value was green on the other side, and the green light represented that the energy value was full.

"Alright, your navigation robot system is on."

"Okay, I'll pay."

"Follow me." The proprietress took Bei Yi Nan to the front desk.
