Grandpa, she can't be a woman

Chapter 527 Xu Mu's Progress

"Master, are you a fairy?"

Children are pure-minded, completely unaware that they were betrayed by their own expressions.

Seeing that Yun Xiao was able to explain the purpose of their running here, the two children looked at Yun Xiao with surprise and admiration in their eyes:
"My grandma said that only gods know everything!"

"I don't know everything..."

Yun Xiao laughed:

"For example, how far have you progressed?"

"Master, look!"

After all, it was a child's heart. As soon as they talked about the results of their recent efforts, Xu Mu and Ya Dan's attention was immediately diverted from the question of "Is Master Yun a god or not?"

The two took out the drawings that had been hidden behind their backs before,

On it is a pair of crooked lines, which looks very immature, and requires a little imagination to understand.

"All we had been thinking was just to keep Grandpa from falling off his chair when he reached for something.

But then Ya Dan suddenly said that when Master gave us homework, he was clearly talking about helping people like my grandfather solve problems,
And my grandfather's biggest problem, is that he has limited mobility, unable to move by himself! "

Xu Mu raised his head, on his small bronze face, there were two groups of red frostbite,

But the eyes he was looking at Yun Xiao at the moment were astonishingly bright:
"So we thought, how can a person be able to sit or even lie down and move?
Then we thought of the carriage we had seen on the outside road before!
Master, look! "

While talking, Xu Mu pointed to his crooked painting:
"The upper part doesn't look any different from the chair with back and armrests that my grandfather used to sit on.

But as long as the chair legs below are changed to wheels, when my grandfather wants to move again, he doesn't have to let my father carry it in and out.

As long as my grandfather sits on this chair, my dad can push him around! "

"Good idea."

After waiting for so long, I finally got a practical solution.

Although they have only turned the four legs of the chair into four wheels so that the person sitting on it cannot turn the wheels by themselves, they still need to rely on external force to push them.

But it is extremely difficult to take this step independently with a sense of innovation.

Yun Xiao nodded approvingly, and in her smiling voice, apart from praise and tolerance, it was more of a kind of persuasive guidance:

"But you also said just now that your grandfather's biggest problem is that he cannot move by himself.

Of course, this chair with four wheels, when there is a wall or other heavy objects next to it, your grandfather can also rely on the force of his hands to push back the external object to move himself,
But what if it's on an empty street?
Do you think there is any way to continue to improve the current picture so that your grandfather can move by himself even if he is alone in a particularly empty place? "

"alone……"

With the success of the first step, when Xu Mu and the others heard Yun Xiao's words that seemed impossible to realize, their first reaction was no longer to question, but to think seriously:

"If you want to move the wheel by yourself, the most direct way is to push the wheel with your hands.

But……"
