Only, Huang Yuzhu showed a troubled expression. He said embarrassedly,
"My scale can only weigh up to a dozen or so pounds."
The kind that could weigh a hundred or two hundred pounds did exist in Huang Yuzhu's home, but they were too big, and he felt uneasy about moving them over.
Cui Yu was stunned.
The ever-reliable Yu Zhu had actually failed.
"Cui Yu!" Pang Jiao called out to him like she was summoning a soul.
In the midst of panic, Cui Yu's brain cells spun rapidly, and suddenly, like breaking through the clouds to see the sun, a flash of inspiration struck him, he had an idea!
Cui Yu said calmly, "There was just a small error earlier, I have a way to compare your weights."
He pointed towards the window:
"Look at the protrusions along the window sill, we can set up a desk there, one of you sit at this end of the desk, and the other sit at that end, using the principle of a seesaw, couldn't that easily determine who's heavier and who's lighter?"
