"You can make one round over all of them before repeating the process again," William paused, "I believe five rounds is enough with all the amount of substance we got here. And don't worry about the amount of spirit power used, the substance will absorb a fixed amount per second, and will get absorbed without wasting too much power."
"Ok," Kong nodded, "what is this substance used for then?"
"A diversion," William mysteriously said, and no one here understood his meaning.
"Fine," unlike what everyone else expected, the newly arrived Kong didn't delve much about this topic as if he didn't care about any of this.
Under the fourth elder orders, he got to leave the frontline and come here to help this bunch of weaker spirit masters in doing something.
The fourth elder didn't stress over the matter, and that made Kong realise it was nothing of utmost importance.
Kong planned to finish his task here fast before returning back to the frontline.
