289 Unsolved Mystery

Sand was blown around unceasingly by the wind outside the castle walls.

A huge arched gate appeared ahead of the carriage.

The gate was closed, and only when a scholar, a great sage, paid a visit would the Wind Castle open its door.

Beside the main entrance, there was a smaller gate which was also tightly locked.

There were two banana trees outside and under the shadow of a banana tree, a youth was sitting on a rattan chair, reading a scroll with deep interest.

It looked like the sand blowing a few steps away had nothing to do with him.

Indeed, the banana trees were inside the barrier surrounding the whole Wind Castle.

The sand outside wouldn't be blown in.

This was the Wind Castle's natural defense mechanism. Without being allowed in, nothing could get inside this holy city.
