Who are these three people looking for?

The first two people are easy to find, both in Dawang Village. One is a swordsman, the other is Sima Yanzi, but the third one is hard to find. After searching for nearly an hour, I wasted n blood and finally found it (by the way, I despise perfection.

I wore Qingyun +8 sets, and I was hurt by monsters at level 69, all of which were 100+ blood). Closer to home, the third person is the legendary ghost doctor (-38 1, 334). I'm glad I found it, but then he made what I was looking for even more disgusting. Fishing bait.-okay.

When fishing, you can go to Zuoguan Fish to collect it.
