Suddenly, a small explosion appeared, and Lin Mu's hand was pushed back.
"This… I did not expect this…" Xukong said.
Lin Mu could hear the shock in his master's voice and knew that he probably discovered something beyond what was in the normal scope of things.
"What's the matter, senior? Is it not Ice Elemental spirit Qi?" Lin Mu questioned.
"No… it's not." Xukong said, his voice low.
"Then… what is it?" Lin Mu questioned as he looked at the crystal that was half gone.
The fire elemental spirit Qi in his hand had also been consumed entirely by it. Lin Mu couldn't tell if this was a test that was positive or negative. With no clear conclusion on his hand, he could only wait for the master to answer.
"This Qi… it's actually Yin spirit Qi…" Xukong stated.
"Huh? Yin spirit Qi?" Lin Mu asked, feeling confused.
