172 Is Yunjin as Heavy as a Boar?

Lu Jiao knew right away that Uncle Youcai was done with the wheelchair. She happily entered her home with her basket. 

Inside the bedroom, the four little ones heard noises and ran outside to sweetly smile at Lu Jiao.

"Mommy, you're back!"

Lu Jiao patted their heads and went into the bedroom with them. 

Inside, Uncle Youcai explained the mechanics of the wheelchair to Xie Yunjin, "For this wheelchair, the most important thing is this wooden bearing. Regular wood is no good for this. So I went into the mountains to find a sturdier and harder wood. This is why it took me so long to finish."

Uncle Youcai chuckled out of embarrassment. Only now did Lu Jiao realize why this wheelchair took so long. He made a good point - if he used normal wood, the bearing would snap very quickly after a while.

Lu Jiao thanked Uncle Youcai, "Thank you."

Xie Yunjin did the same.
