Training in Cage

"Alright, after you make your decisions, you have to be responsible for your Familiars. I hope you persist in your choices."

On the first day of training, a military instructor came to pass on his experiences.

The instructor looked young and energetic in his dark-green military uniform. He walked fast, with a bag in his hand.

He put the bag on a table, then took out several wooden sculptures.

"Today I'm going to demonstrate how to maximize power," the Instructor said concisely.

"Different Familiars have different ways of attack, but generally they are similar. For example, many of them use teeth, tail, legs or horns to attack."

As he said this, the instructor suddenly stretched his right hand, and his four fingers closed together like a knife.

Zap!

His hand split the wooden sculpture!

Students were shocked; why did this teacher perform without warning?
