"Luo Yuan!" The students were already very familiar with him.

Charles sighed: "How did you get in here again?"

Luo Yuan blinked, "I was standing at the door, and someone opened it for me."

"What do you mean when you say pheromones and mental strength are not simply promoted?" a student grabbed him and asked.

"Hmm." Luo Yuan thought for a moment, "I feel like they grew more like they were growing at the same time. They might have influenced each other, but there's no telling which one promoted which."

"Isn't that right, Teacher Li?" He looked at Charles eagerly.

Charles twitched his lips.

"The view currently held by the academic community is that spiritual power is innate. If you have it, you have it. If you don't, you don't."

“Once awakened, the only thing that can affect it is its health, just like a plant rooted in the soil. The more fertile the soil, the better the plant will grow.”

"But the level of spiritual power is determined at birth, just like whether a plant is a flower, grass, or tree is determined when it breaks through the soil."

"No research has shown that pheromones have any relationship with mental strength."

"It's over!" the students wailed. "We're going to fail the course!"

Charles sighed: "I suggested that you not choose this topic."

"Think about it, spiritual power awakens at the age of 11, while the time of differentiation is distributed between the ages of 15 and 35. If the two are related, why is there such a huge difference?"

The students wailed again.

Luo Yuan tilted his head.

"Not necessarily, Teacher Li."

Charles frowned. "All children in the Empire take the awakening test at the age of 11. There are no exceptions."

Luo Yuan showed a surprised expression, "But I'm not."

He patted his chest.

"My spiritual power awakened when I was 7 years old, and it was also at the age of 7 that I differentiated."
