Chapter 424: Purple Firmament
Behind Lingxiao Peak, deep within the forbidden ground.
An ancient palace was embedded in the mountain body.
At the palace center, a massive pill furnace burned fiercely.
That was precisely Lingxiao Upper Sect's sect-suppressing supreme treasure.
The Purple Heaven Refining Sky Furnace!
The furnace stood over five zhang tall, entirely pale gold in color. Its body was round and ancient, its surface branded with countless intricate and mysterious patterns.
These patterns weren't carved by human hands, but seemed naturally formed. As flames within the furnace leaped, faintly visible purple-gold radiance flowed through the patterns.
Most astonishing were the flames burning within the furnace.
They were pure purple flames, neither ordinary fire nor True Origin transformed. The flames rose from the furnace bottom, reaching three zhang high. At the flame core, the purple turned almost black, while the edges showed faint golden borders.
