Sam was now looking at his parents and sister. All of them are now practicing the energy mode that Sam recently taught them. All of them were very interested in Sam's technique and because of this, they were practicing the technique very seriously. Well, this energy mode wasn't as hard as the spirit technique, but it also wasn't easy to learn. To master this technique, one needs to have good control over spiritual energy. If you don't have good control over your spiritual energy, then you won't be able to control the spiritual energy when transferring the spiritual energy to your sword.
