In the Magician Academy classroom, a lot of students were sitting in their seats when the doors to the room opened and walked in Instructor Nina Olsen.
"Hi guys, today I will be teaching you about a magic technique that will help you control the magic energy inside your body. So, Listen well! The name of this technique is energy control. You only need to memorize twenty hand signs and execute them in the correct order to activate the energy control magic technique. I will perform them three times, so remember them by heart. There is no handbook for this technique, so do your best to learn it in class." Instructor Nina Olsen said in a loud voice, making sure that her voice reaches the ears of every student in the class.
"Do you understand?!"
"Yes, ma'am!"
