You will find Kyononis Shrine in Hyrule Field, north of Lookout Landing.
Combat Training
After you go down the stairs in the shrine, look to the left to find a Rusty Broadsword and Rusty Shield. If you don't have a small sword and shield, you can take these. Be sure to equip a small sword and shield.
Approach the Construct in the middle of the room, and it will instruct you on various combat techniques: Side Hop, Backflip, Perfect Guard, and Charged Attacks. Perform the correct action at the right time and you can do a Flurry Attack by tapping the indicated button.
The Charged Attack will defeat the Construct. Take the items that it drops, then go through the door that opened and open the chest to get a random Zonaite Sword.
Check on the glowing object ahead to get a Light of Blessing.
