บท 456: Kicking the governor (6)

"It's clearly flat, how can it be round? Don't the round ones have curves?" Zhuge Cang Xiao asked.

"That's because the curve is too big. That's why you feel that it's straight and flat. For example, if this circle is only one foot in size, don't you think its line is very curved?" A foot-long circle appeared on Tang Wen's face.

"Yes, it's very curved." Zhuge Cang Xiao replied.

"Then I'm going to enlarge this circle." Tang Wen nodded again, and the one-foot long circle became one meter."Look again now, does the curve become smaller?"

"Yes, yes, I've become smaller. Why didn't I think of this before?" Zhuge Cang Xiao nodded his head repeatedly, his face filled with excitement.

"Hehe, what if it's bigger?" Tang Wen pointed again, and the circle continued to expand. In the end, it actually expanded to the wall and grew to a diameter of seven or eight meters.

"Look at it again now, isn't the curve less obvious?" Tang Wen said with a smile.
