Lin Yun didn't know what the best level-9 spell was to copy, because there were too many level-9 spells that he wanted to choose. No matter which of them was copied to the spot, its ultimate version and its greatest feature would be displayed. It would not be just as powerful as a level-11 spell; it would have the power to change laws.
Lin Yun continued understanding laws and studying truth runes and the Source Chapter. He even planted the branch of the Eternal Tree in the southeastern side of the Natural Demiplane, waiting for it to sprout and grow into a life tree. Then, if he took care of it as planned, he could possibly restore the power of the Eternal Tree in it, which would be of tremendous help to intelligent lives to be born in the Natural Demiplane.
Xiuban, Reina, and the legion mages had always been sent to the battlefield for practice. They were all in the phase of rapid growth, and it was very easy for them to level up in such a war.
