"Brother Sect Leader, why is the emergency call number 110?"
"Why is the fire emergency number 119? And the medical emergency number 120?"
At Changchun Temple, the science education mini-class is online once again.
Ning An sipped his tea with a smile and said, "Does anyone have a Lu Ban Ruler at home? Send over a photo."
Sure enough, the netizens were quite reliable.
Except for not being able to find a girlfriend, they could get hold of any kind of photo.
Soon, the live stream was flooded with dazzling images of Lu Ban Rulers.
Ning An casually clicked on a picture, pointed at the Lu Ban Ruler, and said softly, "Look, on the Lu Ban Ruler, one hundred and ten centimeters corresponds to 'official,' one hundred and nineteen centimeters corresponds to 'fire,' and one hundred and twenty centimeters corresponds to 'illness.'
"Do you think this is a coincidence, or was it done on purpose?"
The live stream viewers were taken aback and instantly caused an uproar.
