"I don't know for the time being, but this guy is too fast. I perceive that both times are passing by in a flash. I can't find the other person hiding there. I only know that it should be on the bookshelf in front of me!" Su Ruoxi said lightly. .

Gu Nan got some interest when he heard that, and rolled around on the Dark Soul Eater for a few times, and he was awake...

"Master, where is it?" Gu Nan asked curiously.

"You can't see either? I only saw a blue light just now..." Su Ruoxi said.

"I haven't found anything in the bookshelf in front of you for the time being!" Gu Nan said.

"Wait and see..." Su Ruoxi said.

Then, Su Ruoxi began to flip through the books on the shelf in front of him unintentionally. He picked it up and looked at it seriously in his hand. Not long after, Gu Nan shouted, "My fellow master, under the bookshelf on the left, grab it quickly. Live it..."

Su Ruoxi didn't make a sound when he heard the words. He didn't even lift his head, and didn't even move. He asked in his heart, "Do you see what it is?"

"I didn't see it clearly, I saw a blue light..." Gu Nan said, he was curious at the moment, the opponent's speed was extremely fast, and it really passed by in a flash, no wonder even the master would call it...

"It's okay, we'll just wait..." Su Ruoxi said in his heart.

After confirming that there was something in it, Su Ruoxi left in no hurry. He leaned directly on the bookshelf behind him, picked up a book casually, and pretended to look at it seriously. The other party seemed to realize that Su Ruoxi could not find it It's like...

After a while, I kept flashing in front of Su Ruoxi. Every time I flashed, I would hide and observe Su Ruoxi. After discovering that Su Ruoxi hadn't found it, he became more courageous and went directly to the opposite of Su Ruoxi. In a book, quietly watching Su Ruoxi...

Su Ruoxi's spiritual sense did not approach, nor did he look at the other party, but Gu Nan saw the other party clearly this time, but he was even more puzzled after seeing Gu Nan clearly: "My fellow master, I have never seen this thing. !"

"Huh? Haven't seen it? What is it?" Su Ruoxi asked.

"Blue, round, fatter than me!" Gu Nan thought for a while and said.

Su Ruoxi...

"Xiao Bai, see what it is?" Su Ruoxi asked directly, taking Xiao Bai from the medicine field.

"Huh? The master turned out to be Bing Xin. If the master can absorb it, he won't have to practice the mysterious skills of ice attributes in the future!" Xiaobai glanced at the little thing hidden in the bookshelf opposite Su Ruoxi.

"Bing Xin?" Su Ruoxi asked.

"Yes, Bing Xin is actually the essence of the heart derived from the mysterious technique above the top ice attribute, but it is very rare. It seems that there was once a mysterious mind method above the top ice attribute in this library. Become Bingxin! Such a mentality is very rare, I am afraid that there is not necessarily a book on a continent. My former master once encountered a fire heart, a mysterious with top fire attributes. It's a pity that I didn't catch it..." Xiaobai explained.

"It turns out that there is still this kind of operation, how can I catch this Bingxin?" Su Ruoxi asked in his heart, no wonder Xiaobai's front master didn't catch it, and she was not sure of the opponent's speed. Otherwise, it wouldn't have been so long for a long time.

"Master, I don't know this either, or else you try to use the ice attribute profound energy?" Xiaobai thought about it and said.

"Alright!" Su Ruoxi said after hearing the words, feeling reasonable.
