Xia ruofei knew that the time was right. He carefully opened a small gap in the space that he had confined and guided the spiritual power that had almost been condensed to the extreme to leak out from the small gap.
Just like that, his spiritual power was pulled into a thin line.
Although it was almost invisible to the naked eye, Xia ruofei could clearly sense the existence of this thin thread of spiritual power.
He immediately followed the shape of the rune in his mind, guiding the thin thread of spiritual force to extend, turn, transform, and shuttle ...
Xia ruofei could feel an invisible rune slowly forming in front of him.
This process was very slow. Under his careful control, it took him more than ten minutes to complete less than thirty percent.
Besides, the runes were too complicated. Xia ruofei felt that there was only a slight deviation in the control and the runes he drew were already wrong.
