The moment these words were spoken, Cheng Buzheng immediately lost interest. He had taken a Youth-Fixing Pill in his early years; until the day he died, his appearance would not decline in the slightest.
For him, that was already enough.
Thus, Cheng Buzheng now had not the slightest interest in such Spirit Pills or secret arts.
Besides!
In the dog-eat-dog Cultivation World, having an outstanding appearance was hardly a good thing.
Fortunately, his wife had always listened to him, using divine abilities to conceal her peerless beauty every time she went out.
Naturally, he had no need to worry about his wife.
However, pursuing an even more peerless, ageless appearance had always been something Female Cultivators cared deeply about!
Therefore, Cheng Buzheng did not refuse.
Nor could he refuse his wife's request.
After all!
He currently lacked none of the resources needed for his cultivation, and even his wife's cultivation resources were more than abundant.
Therefore!
Spending a few Spiritual Items on something his wife cared about most was only natural.
It could also further the harmony between husband and wife.
Besides!
His wife's beauty, glorious enough to topple kingdoms, bloomed for him alone—what was there to begrudge?
Thinking this, Cheng Buzheng said generously, "What rare treasures do you need?"
Hearing this, Murong Wanwan's eyes instantly lit up. Then, as though she had thought of something, she cautiously said, "There are rather a lot?"
"It's fine. Though your husband does not have many rare treasures, I still have enough to support your cultivation of one secret art."
Cheng Buzheng spoke with complete confidence.
"Then this concubine will say them?"
"Go ahead!" Cheng Buzheng said magnanimously.
"This secret art requires eight rare treasures in total: [Yin-Yang Mystic Gold], [Five-Colored Auspicious Ganoderma], [Nine-Colored Heavenly Fire Grass], [Heavenly Fragrance Marrow Dew], [Heaven-Nurturing Crystal]..."
