Untraceable

Loki was in his room looking at the scroll he got from Tang Ao. Loki chuckled as he remembered how he got the scroll. Once Tang Ao finished his talk with Michael he 'accidentally' bumped into Loki. After they bumped into each other Loki started a conversation which he led into Tang Ao giving him a basic martial art technique. 

Loki already confirmed that there was indeed a new form of energy within him. It was the same impure energy that the people of this world called inner energy. It was weaker than mana but it was more abundant than it. 

'Is it possible to make this inner energy purer?... I guess I should review that later once I get a better feel on how to control it.' 

Loki then studied the martial art technique that Tang Ao gave him. It was a simple technique in which the user gathers his inner energy into his fist or legs to unleash beyond human strength for a few seconds. It was basically the same as his [Enhancement] spell but less versatile.
