As Zhenyuanzi's magical tactics were cast, the lid of the Sun, Moon, and Stars Furnace swung open automatically, and a stream of purple light burst forth, wrapping around the Heavenly Book and the four fragments of the Map of Mountains and Rivers, drawing them into the furnace.
Nezha also opened his mouth and spewed out a swath of red true fire, which was the Samadhi True Fire, enveloping the bottom of the furnace and burning fiercely.
At the bottom of the Sun, Moon, and Stars Furnace were nine orifices, resembling nine mouths, which sucked in the Samadhi True Fire, transforming it into nine delicate threads of flame that wrapped around the Heavenly Book and the Map of Mountains and Rivers, slowly annealing them.
Zhenyuanzi's hands formed spells, and another marvel occurred within the furnace. With a 'puff', a cluster of purple true fire appeared out of nowhere, its temperature on par with Nezha's Samadhi True Fire and even exceeding it slightly.
