Walking treasures

Shane never expected that his mission would be solved so easily.

Instead of having to fight with his precious life on the line, he had asked for the deamon killer fruits, and obtained them easily. 

In exchange, his only task was to follow the old treant that walked slowly out of the valley, straight into the opposite direction from which Shane came.

Its strides were large, and with every step the treant took, Shane had to take dozens.

Nevertheless, he quickly followed the treant while jogging slowly.

Shane hadn't known how vast the secret realm he had entered was, and it was only after they had walked in a direction for more than an hour that Shane finally realised that everything was far more difficult than he could have expected in the beginning.

Not only was the number of old magi trees huge, but there were many more treants and other similar beasts with an origin in the world of plants.
