I believe many players are not sure about this yet, so today I will let the editor of Sourcecode.com tell you where the Bihai Black Sail Cemetery is. I hope it will be helpful to you!
The location of the Bihai Heifan Cemetery is right next to the Royal Cemetery on the map. You can just transfer it directly to the trade line on the map.
1. The teleported point is the building above. Go down the stairs first, and then go up the stairs on the opposite side.
2. After going up, walk along the road to the right. If you keep walking, you will see another staircase. Just go down the stairs .
3. After going down, you need to go to the right. Nearby you can find an area called the Island Bonfire. Follow the prompts to complete the task.
