[old biker]

Assume that you have a very old factory. The old factory has a backyard and many rooms for the workers in the factory. As the factory is very old and so the factory is not functioning for a decade. And so you use the backyard as shed for your race horse. Unfortunately you lost your factory key today. So use your skills problem solving skills and puzzle solving skills to collect the necessary items in the factory to escape your race horse in the factory

Good luck
