The Enchanted Bridge

Once upon a time, there was a small city in the middle of the jungle. The only way to get there was to cross a bridge. Under the bridge was a large and dangerous river. The citizens of this city realized that civilization was getting closer and closer to them. All the trees were cut to make new houses. They were afraid that someone would discover the bridge and get to them. They called all their citizens for a meeting, and in this meeting, they decided to enchant their bridge. They made it invisible and they made themselves invisible too.
