How to unseal the Village Lu well in Phantom Blade Zero

When you're exploring the Village of Lu in Phantom Blade Zero, you'll come across bosses, hidden areas, and much more. However, the one main task at hand is to unseal the Village of Lu well and remove the thread covering it. You need to do three things in the open area to do that, but it's not immediately clear what those things are. I found myself running around madly trying to find the last thing I needed to do to unseal the well, so here's a walkthrough you can follow.

How to remove thread from the Village of Lu well

You need to do three things to unseal the well in Phantom Blade Zero. They are:

• Beat Master Bi Hai of Kuye Temple
• Beat Master Bi Yuan of the Tianxuan Sect
• Kill the engine giant remains

The first of the two bosses you'll face is Master Bi Hai of Kuye Temple in the Lady Grounds area of the village. The first set of threads will disappear once the boss fight is over.

The second boss fight is with Master Bi Yuan of the Tianxuan Sect, while you'll find at the north end of the map if you follow the story quest in the area.

Finally comes the unclear part, which the game doesn't point you towards. You need to head to the northeast part of the map, by the bell called Engine Giant Remains, and head inside the building there.

You'll notice a figure connected to the big thing in the middle of the room by a sword or pole. It won't move or fight back, but attack it to destroy it. That will remove the final seal from the well, so you can head back to it and jump inside.
