The snow in Kunlun Ruins has been falling for three thousand years.
When the whisk of Master Xuanqing's fingertips swept across the top of the alchemy furnace, the seventh ray of purple lightning struck the eye of the Locking Immortal Formation. He originally thought that this catastrophe of the Immortal Sect that had been guarded for a hundred years would finally be able to protect the last trace of the Immortal Veins with the Nine Turns of Resurrection Pill, until the cluster of faint blue fire emerged from the cracks of the elixir furnace - it was not the blazing fire of ordinary fire, nor the warmth of the Immortal Fire, but the underworld fire that could entangle the soul and even burn the Immortal Bones.
The first one to scream was the disciple guarding outside the alchemy room. When Xuan Qing turned around, he only saw half of the immortal body still burning. The fire climbed up along the sect jade pendant around the disciple's waist, even gnawing cleanly at the wisp of immortal essence sealed in the jade. He hurriedly made seals, but the most excellent Taoist Qingxin Mantra shattered into powder the moment it touched the underworld fire. The tongue of fire licked his sleeves, and a biting coldness penetrated along the meridians to his Dantian, which was colder than the deepest ice abyss in Kunlun.
"Real person! The formation is broken!" The hoarse cry of the elder came from outside the mountain gate. Xuanqing raised his head and looked at the sky. The Immortal Locking Formation that was originally shrouded in golden light was now being woven into a giant net by the underworld fire. The fires poured out continuously from the void, burning down the cornices of Lingxiao Palace, melting the Tongtian Pillar that held the mountain, and even the fairy mist that lingered on the top of Kunlun all year round was burned into black smoke with a burning smell.
He still held the last Nine Revolutions Resurrection Pill in his arms, which was refined with the hard work of 360 immortal disciples. It was supposed to be used to reshape the roots of immortality and continue the path to immortality. But when the underworld fire climbed up his clothes, Xuan Qing suddenly understood that the fire was never going to burn the Kunlun Ruins.
