Part of the main story of The Legend of Zelda: Tears of the Kingdom sees players have to find solutions to all the puzzles in a dungeon called the Construct Factory to help Mineru, the Sage of Spirit. The quest "Guidance From Ages Past" eventually directs Link toward the dangerous region of The Depths to find this Factory. Also known as the Spirit Temple, this quest has a lot of parts and can take quite some time for players to complete.
One of the challenging parts of the Construct Factory comes from trying to reach its location in the first place. The Depths are a notorious area filled with hazards that can inflict the terrible Gloom condition onto players in Zelda: Tears of the Kingdom. Players are recommended to activate the Muokuij Lightroot close to light up the dungeon and so that they can come back quickly without having to navigate the area again.
Guidance From Ages Past Quest Guide
After players find a special mask behind a locked door in the "Find the Fifth Sage" quest, a laser points to the Spirit Temple, where Link must collect four pieces to a golem to help Mineru. The Sage of Spirit wants a body from the scattered parts of this Construct in Zelda: Tears of the Kingdom, which is divided into the Right-Leg, Left-Leg, Right-Arm, and Left-Arm.
Players need to explore four separate Construct Factories in the Temple to bring back the golem parts to a central mold in the area. By using Link's new Ultrahand ability in Zelda: Tears of the Kingdom, players are able to attach the parts to the right section of the mold to assemble the golem. Every section of the Temple has a connecting Depot that hosts a puzzle hiding a golem piece that players have to solve.
How to Solve the Left-Leg Depot Puzzle
Traveling to the Left-Leg Depot gives players the option to activate a terminal to seal off the area and release a container holding the golem's left leg in Zelda: Tears of the Kingdom. From here, players can use Ultrahand to move the container to one of the two baskets to their left with Zonai rockets attached. By hitting the Zonai rockets once both Link and the container are in the basket, players can move up to the main puzzle of this section.
A high platform above a body of water prevents players from progressing with the container, with a stone ramp and a crank also in the room. There are loose Zonai rockets lying around here, as well as a 
Steering Stick . Turning the crank moves the ramp up and down, giving players an angle toward the open ledge of the higher platform. Using fusion in Zelda: Tears of the Kingdom, players must create a contraption to fly off the ramp.
Using at least two rockets and one steering stick gives players the best contraption in Zelda: Tears of the Kingdom when attaching all these Zonai devices to the golem part container. The steering stick gives Link some measure of control before hitting the rockets to try and reach the high platform. If players miss, a nearby dispenser can give them more rockets to easily try again by adjusting the angle of the ramp.
After this, players can go to their right to find a chest past a set of lasers that contains some Zonaite in Zelda: Tears of the Kingdom for their troubles. A path leading down brings players back to the golem's mold, where the container breaks for them to attach the part to the left-leg spot.
How to Solve the Right-Leg Depot Puzzle
It can be quite hard to find this Depot, so players should use Ascend in Zelda: Tears of the Kingdom to get to a higher spot in the Temple to spot the entrance to this Factory to their right past a broken set of platforms near a large skeletal spine bridge. Once again, activating a terminal gives players a container with the golem's body part while sealing off the area. A couple of baskets with Zonai fans help propel Link up to the main puzzle much like before.
A rail can be seen here leading to another high platform opening, with a hooked stone slab already hanging on it. Players can attach the container to the slab, then connect one of the Zonai fans in Zelda: Tears of the Kingdom from the baskets onto this new structure. Hitting the fan causes the container and slab to move forward along the rail, moving both to the higher platform.
At the top, players will be able to see the golem mold far below them at the Temple, along with several gliders, steering sticks, and more fans. Assembling a glider powered by at least two of these fans lets players attach the container to this contraption, which should easily take them back down to Mineru in Zelda: Tears of the Kingdom.
How to Solve the Left-Arm Depot Puzzle
From behind the golem mold in Zelda: Tears of the Kingdom, players might see the Left Depot entrance on a platform to the right of the Temple, where another terminal can seal them in for this puzzle. This arm container is a bit bigger than the legs, so players will have to adjust while using Ultrahand. Hitting a Zonai wheel on a nearby door lets players enter a room filled with lava which represents the big obstacle in this section.
The container can't move on the path covered in lava, forcing players to build a contraption using the wheels from the door and a steering stick on the ground. By putting all these items on the container, players can make a small car of sorts, which may be driven over the lava path. To their right from the end of the path, there is another track through lava in Zelda: Tears of the Kingdom that must be driven over once again.
However, this path is narrow compared to the previous one in Zelda: Tears of the Kingdom, so players will need to disassemble their car and remake it for the container to fit in between two grates making the path smaller. The puzzle ends here as players come across a waterway leading back to the golem, which they can navigate by attaching some nearby Zonai fans to the container to transport themselves down.
Before going through the door prior to the waterway, players can also grab a Grand Poe at the top of a long ladder. Additionally, a small chest rests on spinning fans powered by the Zonai devices used on the container. This chest can be moved with Ultrahand, and holds materials from Zelda: Tears of the Kingdom for the players to collect.
How to Solve the Right-Arm Depot Puzzle
The final Depot may be seen to the player's left from the golem, past the waters of The Depths and a collection of trees. Players may reach the higher platform with the Depot's entrance by using Ascend to travel through the large stones that make up the platform itself. The final terminal and container await them in a room soon to be sealed off like all the others in Zelda: Tears of the Kingdom.
The room here holds a massive collapsed pillar over a large gap, which has a current of electricity constantly moving through it. Several Zonai Wheels in Zelda: Tears of the Kingdom powered by electricity sit nearby, giving players a chance to attach them to each side of the container. Not only does this let the container balance on the pillar, but players may also activate the wheels to send the golem's right arm across the gap without it dropping into the darkness below.
The darkness is not dangerous though, since players can glide below the gap to use Ascend again to reach the other side themselves. Hitting the wheels again to deactivate them lets players drag the container to the Depot's exit, where the Temple can be seen below. A steering stick and more wheels close by allows players to build a car much like in the Left-Arm Depot to transport the golem part back to the Temple in Zelda: Tears of the Kingdom.
Once all the puzzle solutions for the Construct Factory dungeon have been found in The Legend of Zelda: Tears of the Kingdom, Mineru will gain their new body for Link to drive, leading players to a sudden boss battle.
