Memo: Secondhand Terminal

Crap, I don't know what to do with this waterwheel.

All those books at home were stored together with the family records. Even if it hasn't been over a hundred years, it must've been seventy or eighty at least.

All these years in the Stockade, each family has passed down their own skills, and they've dwindled more and more...

All that's been passed down in our family is some skill with electrical circuits. This waterwheel issue doesn't seem too related to that.

Who even remembers how to fix a waterwheel? He Lao, or someone else? Whose grandpa or uncle had that skill anyway?
