You eavesdrop on Stonefang and Lang Tou's conversation, and learn that Tangtang is near the waterwheel.

AHEM... Chief is really working herself to the bone! Hardly see her nowadays.

Chief's got no choice, bro. Ruan Yi's underlings are recruiting more to their side. Said they wanted revenge... That's some serious trouble on her hands.

If only there was someone to keep her company and talk with her!

Yeah. If someone like that were around, Chief wouldn't be all alone on her own near the waterwheel!

(The waterwheel... Thanks.)
