Of course, in order to do this, Lu Yuan would need a huge amount of spiritual stones as support.
Fortunately, he had just finished a big business deal with sect leader, Mu Chen.
One thousand spiritual energy phones would cost 3,000 mid-grade spiritual stones.
It was equivalent to 300 high-grade spiritual stones.
If Lu Yuan wanted to reach the peak of Core Formation Stage in a hundred years, he would need at least one high-grade spiritual stone a day.
Therefore, although 300 high-grade spiritual stones seemed to be a lot, it could only last him for half a year at most.
Fortunately, as long as the spiritual energy phone was sold, Lu Yuan was confident that he could get at least two or three mid-grade spiritual stones from each spiritual energy phone.
Moreover, the market for spiritual energy phones was huge.
