Previously when Yuehua was lecturing, Yi Yun listened attentively. The first volume of Su Jie’s notebook Lin Xintong left him was also on energy extraction.
Back then, Yi Yun did not understand a lot of things, but after listening to Yuehua’s lecture, and seeing Yuehua’s demonstration of the methods, he compared it with the descriptions within Su Jie’s notebook. As such, Yi Yun began to understand many things he previously did not.
With Yuehua’s demonstration, Yi Yun could use his energy vision to see every seal she made clearly. He could see how the energy changed and moved, allowing him to keenly grasp it.
The other Desolate Heaven Master apprentices, even Luo Huo’er, would not be able to see it so clearly.
With theory conjoining with practice, Yi Yun had a general idea about the extraction of the Power of Desolates. With the Purple Crystal’s help, extracting the energy from desolate bones was no longer difficult for Yi Yun.
By recalling the ten theories of Power of Desolates extraction, Yi Yun made his move. He chose a high-grade general-ranked desolate beast’s bone. This grade of desolate bone was not easy for a Desolate Heaven Master apprentice!
Actually if Yi Yun wanted to, he could even extract the energy from a primordial species’ bone. But this would have been too shocking.
With some light finger movements, the energy within the desolate bones were now rapidly being pulled out by Yi Yun.
In the Purple Crystal’s energy vision, Yi Yun could see the light dots flying around like fairies all over the classroom.
But no one could see the light dots condensed by the Purple Crystal.
No matter how grand the scene was, the people around him were blind to this.
