Excited at the various methods the clerk had mentioned, Di Tou couldn't help but feel that an expert's advice was helpful. After all, in the end he was trying to approach things based off his understanding of the modern world. When it came to the actual methods commonly used for cultivation, Di Tou had to admit he was a bit clueless.
"Ah, wait… The formation, does it need to use Qi?"
"Oh, err, it ideally does use Qi, but it can also be run using Spirit Stones, or if the density of the Qi in the environment is high enough, it can also be run directly by using the environmental energy. In your case, you could probably activate it using your Spiritual Sense, and then it would run for about an hour, consuming one Low-tier Spiritual Stone in the process."
Nodding, Di Tou couldn't help but feel relieved, ah, it seemed like batteries were the solution to everything in the end.
