The True Mentalist.

You Xi Wang and You Zhichi kowtowed the lady. Griffin Tallus smiled and said in a calm voice, "Get up you two." 

The two youths stood up. The boy was surprised when he properly saw her face. The lady smiled, "You cannot read my mind. Can you?" 

You Xi Wang did not hide and shook his head. He asked, "Why is it so, Great grandmaster?" 

Griffin Tallus smiled and said, "Firstly, you can call me grandma. What is with this mouthful great grandmaster? Secondly, the reason you cannot read my mind is that before I passed this knowledge to Animus, I developed the protection methods. As the time passed, my understanding and research on this topic had advanced to the level where I can read the spirit energy in the world."
