Sam is currently busy using the techniques for his students. Well after opening those gift boxes he got many techniques. You have to say that he was quite lucky to get those techniques.
But not all those techniques would be useful to his students and because of this he decided to select only those techniques which would be useful.
You also did not want to keep them using many techniques at once as this will make them unable to train those techniques properly.
If you have multiple techniques then you would not be able to focus on any of those techniques. You will need more time to increase the level of those techniques.
Because of this, Sam will also not give them all the techniques. Because of this, he is choosing those techniques for his students.
Suddenly Sam became interested because he could sense someone coming toward his room. He already knows who it is and that makes him quite surprised. It is Jennifer who is approaching his room.
