"I naturally wouldn't doubt you, Daoist Lu."
The middle-aged cultivator, stared down by Lu Xuan, took two steps back.
"I only wanted to understand a little more about your planting method, Daoist Lu. After all, I paid more than thirty Spirit Stones for it."
Hearing this, Lu Xuan gave a cold laugh.
"Fine. Then let me ask you—did the quality of the twenty Spirit Firefly Grass plants you harvested improve or not?"
"Compared to before, there were two or three more Good Grade Spirit Firefly Grass plants. The number of Superior Grade ones didn't change."
The middle-aged cultivator answered truthfully.
"Then doesn't that settle it?"
"Two or three more Spirit Firefly Grass plants went from common grade to Good Grade, and that's when you haven't even been using refined cultivation for long. If more time passes, the average quality can still rise a little further."
"Three more Good Grade plants means nearly one extra Spirit Stone earned. If you plant several dozen or a hundred Spirit Firefly Grass plants, that's several Spirit Stones more, give or take."
"Spirit Firefly Grass is a No Grade spirit plant, with a short maturation time. You can grow three or four batches in a year. In that case, you only need a few years to earn back that sum of Spirit Stones."
"Not to mention, this method is also effective on other spirit plants."
"So, Fellow Daoist Zhou, what else do you have to doubt?"
After Lu Xuan finished speaking, he paid the middle-aged cultivator no more attention and strode away.
He had not gone far before the man grabbed him.
"I gave up most of my cultivation time and paid so many Spirit Stones, just to earn that tiny bit of Spirit Stone?"
"Today, you have to tell me the trick behind it.
