How to get & use Dirty Mechanical Part in Honkai Star Rail

Honkai: Star Rail isn't short of hidden objectives that can be a little frustrating to complete as the Mission navigator won't guide you through these easter eggs. One Hidden Mission chain involves a Dirty Mechanical Part, an Old Tin Box, and A Bottle of Draconic Tears. If you pass these items on to people who have better use for them, you'll be rewarded with a book and personal satisfaction.

I had a hard time finding new owners for these quest items, so here's a complete walkthrough for the entire chain of events. You can use the Table of Contents below to skip to the part you're stuck on.

Pawnbroken Handian will give you a clue: a young man just passed by the door of the Jeweler's Pagoda muttering "Revenge... Revenge..." Head directly in front of the shop (the exact location is circled above) to find a Frowning Young Man. Interact with him and select any dialogue option. You'll then be prompted to give him the Dirty Mechanical Part. In exchange, he'll give you an Old Tin Box.

Head north of the Jeweler's Pagoda to find Howard, the person you're looking for. Interact with him and introduce yourself, then select the dialogue option "You seem pretty interested in Draconic Tears." Once that's done, give Howard A Bottle of Draconic Tears to complete the chain of objectives. You'll be rewarded with a readable called On Travel: Arriving at the Xianzhou.
