Confucianism taught, "A gentleman is watchful over himself when alone; he does not deceive himself in a dark room." That was the reason behind it.
Many bad things, once done, would be done again and again.
At first, it might truly be out of curiosity, or for any number of other reasons.
But as time went on, one would sink deeper and deeper.
So there was only one way to prevent oneself from falling into depravity: no matter when or where, and whether or not anyone was by one's side, if something should not be done, then one must never do it!
Once one crossed that line, depravity would be just around the corner!
So even if it was only to achieve his immediate goal, and he had no intention of doing evil, Lu Yang still refused to use Demonic Arts. Not even once.
Besides, there was another reason Lu Yang had refused Hundred Flowers Fairy.
This woman was too perceptive, too clever.
He had made only the slightest change in his gaze, yet she had keenly discerned his thoughts from it. She was clearly an old hand, having inherited the experience and shrewdness Hundred Flowers Fairy had amassed in life.
Working with someone like her was no different from bargaining with a tiger for its hide.
He could never know when she might scheme against him.
After all, even with two lifetimes behind him, Lu Yang had lived no more than fifty years in total. His life experience was sorely limited.
Hundred Flowers Fairy, on the other hand, had lived for over a thousand years. Among the many King-rank martial artists in the history of the Nine Provinces Continent, she had been one of the longest-lived.
Those long years had given her wisdom and experience far beyond ordinary people.
