"Why can this thing detect earthquakes, Uncle?"
"Father said it's because inside there's a copper column hanging, thick at the top and thin at the bottom. Around it there are eight horizontal bars connected to dragon heads. We're far from the epicenter, so we naturally can't feel it, but the hanging copper column can. If it's hit by the earthquake's waves, the copper column will fall towards the direction of the earthquake, causing a dragon head to push out a copper ball into the mouth of a toad."
This explanation from Lin Muzhi was also what Mr. Lin had told him.
Since it hadn't been verified, he didn't know if it was true or not.
The Second Prince understood some parts, others he didn't, but couldn't quite figure it out.
So after looking at some other things, he simply left with Lin Muzhi.
By the time they reached the front hall, Lin Xingzhi was almost about to be teased in his wedding chamber.
He had drunk a lot today, and his face was quite flushed.
