Lu Xiaotian reached out and beckoned into the void. A cloud of black-gray smoke gathered toward his hand.
"What's this for?" Old Man Kong Yin asked, unable to make sense of Lu Xiaotian's actions.
"Give me what's in your spatial ring. There may be something I can use. If I can refine the blood essence and bodily remnants of that Dharma-Annihilating Ghost Spirit into a pill, it will be the only chance of survival for both of us." Lu Xiaotian stared at the black-gray sphere in his hand, his eyes flickering.
"There was blood essence inside the Dharma-Annihilating Ghost Spirit?" Old Man Kong Yin hadn't sensed the slightest trace of blood essence inside that monster. Even after blasting its body apart, he had sensed nothing besides an aura akin to the Dharma-Annihilating Devil Pool.
"Naturally. It's just exceedingly faint. It has already fused with its Primordial Spirit and the aura of the Dharma-Annihilating Devil Pool, and was even concealed by them."
Lu Xiaotian's divine sense stirred slightly. A profoundly hidden streak of dark red flashed within the black-gray sphere in his hand, appearing and vanishing in an instant like a fleeting bloom.
"What was that?" Old Man Kong Yin was startled. "Your bloodline law has reached great completion?"
This shock was truly no small matter. As someone who cultivated bloodline law, he had encountered quite a few such cultivators in the Celestial Court, with accomplishments ranging from high to low.
There were countless demon immortals under the Honghao Celestial Court, so naturally there was no shortage of those who had cultivated bloodline law to perfection. Yet even they seemed unable to achieve an effect as miraculous as Lu Xiaotian's.
It was already astonishing enough to cultivate the Five Elements and the three wonders of ice, wind, and thunder to perfection.
