In order to speed up the speed at which this kind of crystal emitted energy, one could use a rune array to speed up the passage of time in a local area.
After a short period of calculation, the strange program had designed a time rune array.
Yang Tian took out 28 bluestones from his storage bracelet. As usual, the strange program controlled Yang Tian’s body and began to carve runes on these standard-shaped bluestones.
Compared to the rune array that concealed one’s aura, the time rune array was much more difficult. It would take an extremely long time to finish carving it.
Time slowly passed, and the sounds of cultivators walking or fighting could be heard from outside. No matter how close the sounds were, Yang Tian’s heart remained calm at all times, not allowing his thoughts to affect the strange process.
Carving runes was a very delicate job. With a slight shake of his hand, he would have to re-carve it.
