"This crystal is very hard, I'm not sure I can destroy it without supernatural power." Lin Tian said with a frown as he tapped the crystal in front of him.
"I have seen this crystal before, it does require supernatural power to destroy it, but because our strength is limited, I have another method, this crystal can melt with spiritual flame." Liu Xue said lightly.
"Spiritual flame?" Lin Tian raised one of his eyebrows.
"Yeah, luckily I have that flame." Liu Xue nodded and said with a smile as she let out a small blue flame on the tip of her index finger.
Seeing this, Lin Tian was a little surprised, he didn't expect Liu Xue to have a spiritual flame, he remembered that there were only three people who had a spiritual flame, him, Long Aotian and Liu Xue.
"This is sea heart flame, I got it after stealing it from the Poseidon kingdom." Liu Xue said lightly.
