"Firewood? That interpretation isn't wrong,"
Xu Xinyao followed Xu Yuan's gaze to the ground and said softly, "Through the formation, the Yin Source and Life Origin extracted from those otherworldly and Yin Ghosts are throttled and stored within the Sumeru Ring for neutralization, ready to be channeled out by activating the formation when you need it."

Xu Xinyao, noticing the solemn expression on her third brother's face, hesitated slightly before asking,
"Brother, what's wrong?"
Xu Yuan took a deep breath, looked towards Xu Xinyao, and asked in a low voice,
"I think I understand the principle, but wouldn't this cause a rejection reaction?"
