Construct Factory

Head south of the temple and grab the Muokuij Lightroot to illuminate the back half of the Construct Factory.

Go to the Left-Leg Depot, left of the Lightroot. Activate the Zonai Device to drop a box with a left leg. A gate will close; use Ultrahand to move it to the elevator, then activate the rockets to ascend.

On the next floor, you'll find a pond and the exit. To get the left leg out, use Zonai Devices. Lower the bridge to form a ramp. Attach the box to nearby wings, add a Steering Stick and two Rockets. Use the bridge to glide across.

On the other side, break the box with a weapon and use Ultrahand to fit the left leg into the stone in the middle of the factory.

Go right from the Muokuij Lightroot to the Left-Arm Depot. Interact with the device to get a box with the left arm. Activate the Big Wheel on the stone door to make it rise and drag the box through.

Attach wheels from the back of the door to the box and add a Steering Stick. Place the box at the lava's edge and drive across.

Attach the box to a wheel outside a cage and ride across the lava.

In the next room, hold the door up with Ultrahand and slide the box under it. Pull the box through.

Attach fans and a Steering Stick to the box. Place it in the water, hop on, and guide it down the waterway. Take the box to the factory's center, break it, and place the left arm in the stone.

Head left from the main part of the Construct Factory. Run up the bones and activate the Uisihcoj Lightroot.

Follow the path to the right and cross the bridges to reach the Right-Leg Depot. Summon the box with the right leg. A gate will close; jump on the elevator and activate the fans to move up.

Attach a fan to each side of the box and carry it to the area in front of the cave. Use Ascend to get above the box, then shoot the fans with an arrow to make it rise. Use Ultrahand to bring the box to you.

Use the Wings to glide down or throw the box off the cliff and follow it. Break the box and attach the part to the stone in the middle of the factory.

Go to the Right-Arm Depot in the upper left of the factory. Defeat the Black Bokoblins and Black Boss Bokoblin.

Activate the device and grab the box with the right arm. Use the conveyor belt to go up to the second floor.

Place the box flat on the brown rock to the left of the lighting pillar. Attach a Small Wheel.

Hit the wheel with an arrow to move the box across. Jump down the hole, climb the ladder, and retrieve the box.

Use the wheels in the next room to make getting back to the center easier. Break the box and place the right arm in the stone. The fifth sage will inhabit the robot, and you will begin your journey to the Spirit Temple.
