In The Legend of Zelda: Tears of the Kingdom, the Joju-U-U Shrine can be found on the cliff overlooking the Lakeside Stable in Faron.
Enter the shrine to begin the Building Bridges challenge. Head down the stairs and cross the bridge which will bring you to your first obstacle: a broken bridge. Use Ultrahand to connect this bridge then move on to the next one.
Again, you’ll have to use Ultrahand to grab the second to the last section of the bridge then connect it to the other side. Move on to the next broken bridge. Jump down to the area below then stretch the bridge as far as you can. Grab the 4th piece then connect it to the section under the light. Walk across then make your way to the next broken bridge.
For this one, bring the cube underneath the pole sticking out of the column.
Grab the last section of the broken bridge using Ultrahand then loop it over the pole and stick it to the cube. The cube will be a counterweight, allowing the bridge to stay taunt. Cross this bridge and jump up to the ledge to the left of it. This will bring you to a bridge leading to the altar where you can grab the Light of Blessing.
Along the way, make sure to use Ultrahand on the middle of the bridge and attach it to the column on the left where you can obtain a Large Zonaite from a chest.
