The Matchmaker Red Thread - China

First you need to talk with that uncle here.

Then u go to the village to find the couple. ..

Then Some dark spirit posses the girl. You need to go back to the matchmaker. Its boring i know..
He gives you a pill that you need to give to the girl ... Back to the village again ...

Then you need to go back to the matchmaker once again to report...

And the dark spirits attack the old man. You need to protect him. The spirits are weak so dont worry about the fight :P
