The first person walked up front and grabbed the natural wind conduit. He closed his eyes and focused his Essence on using the conduit.
Assuming that he did not have a core that was aligned with the wind element, the purer his essence the further the large block of wood would go.
The wood was set on a small incline so it wouldn't move with just inertia, and the young man pushed against it.
Everyone on stage felt the wind move around them as a large amount of it was created right in front of them. They saw the wooden block move up the incline and a few officials recorded the distance.
The young man could only keep it pushed until a certain distance before the wind he produced lost enough force to keep the block at a specific place.
"5.2 meters," one of the officials spoke up the number.
The young man breathed once again and walked back. Then, the next person walked up.
