Letter to You 10 Years from Now location (Rattan Hill)

Clue

[Reward on Return] I am looking for a box buried in Rattan Hill. There is a symbol of the Jeok Clan engraved on the box. As ten years have passed, my memory is very dim, but I believe I had buried it near a small stream. The box means so much to me. If you find it, please contact me. Anyone who brings me the box will be rewarded very generously. -Huchon

Story

Huchon made a rueful smile after he read some of the letters in the box. "My brother was always dignified and confident in nature. Tough he let a lot of people down at the Grand Master Trial, I think he will change. Thank you, big brother!"
