This story involves a professor and his students. One night an african professor Leo returned to his flat and was thrilled to see robbers. Those robbers were actually his students who wanted to discover the secrets about his research. Leo did not appreciate that awkward thing at all and made his mind to punish them instantly. It was most unfortunate thing that the method he chose to punish them was Voodoo spells. Since, then nobody ever saw those students anywhere again like they never existed.
