"Heh, people who capsize in the gutter are a dime a dozen. Back then, weren't you and Jun Zhaoying the same..." Wushan could not even be bothered to finish. "Back to the point—there are quite a few ways to keep pills inside the human body from being detected by spiritual power."
"Such as?"
"Such as what is before us: hiding it within a person's internal organs, then using the power of a formation to reverse the yin and yang of the human body. This method defies the harmony of Heaven, but because the blade is hidden within the flesh, it is exceedingly difficult to detect." After all, this was not poison, nor did it harm the body. Even Nascent Soul Late Stage cultivators could not detect it themselves. It was clear that whoever had acted had never intended for the people of this city to return to normal.
"...So, can it be cured?"
Wushan shook his head. "You said the people of this city are connected to the extermination of the Scarlet Pill Clan. In other words, karma exists between the two. This pill is not poison, and judged by its severity, the attacker did not strike too heavily. If I rashly interfere, I would be meddling in someone else's karma. When karmic backlash comes, will you bear it for me?"
Having cultivated to their current level, the two had already seen far too much. Wushan's words did not stir Cheng Wei's emotions in the slightest. "Who wants to bear it for you? You want to study Pill Formations and still have to drag me along—how damaging."
Wushan thought, Could I possibly dissect people to retrieve the pills? He was not an Evil Cultivator. Living people were out of the question, but perhaps he could try one or two corpses.
