The azure flame belonged to Nong Zhen, and he was acutely aware of even the slightest changes within it. Just now, Ning Cheng's Xing He had slightly pulsed, causing the azure flame to tremble.

Ash and slag were separated by the flames, and as the Taixu Zhenmo gold gradually shrank, Nong Zhen focused intently on the diminishing material, continuously inscribing various array restrictions.
