Hun Tiandi was not at all surprised by this scene.
Because the blood blade condensed from the enormous amount of vital blood expended by the Emperor Slaying Array was called the Emperor Slaying Ghost Blood Blade!
After this blade was successfully formed, it needed to be fed the blood of a certain number of cultivators to sharpen its edge.
Otherwise, it would be impossible to bring the Emperor Slaying Ghost Blood Blade's power to a satisfactory level.
At the same time, regarding the choice of cultivators used to sharpen the blade—
The best choice was naturally cultivators who shared the caster's bloodline.
Once cultivators of the same bloodline as the caster were successfully used to sharpen the blade, the Emperor Slaying Ghost Blood Blade could unleash more than ninety-five percent of its power.
If the caster's high-ranking close relatives could be used to sharpen it, its power could reach a perfect one hundred percent!
However, Hun Tiandi no longer had any close relatives.
Thus, this was destined to be impossible.
Even so, when Hun Tiandi saw that he had successfully unleashed this nearly perfect Emperor Slaying Ghost Blood Blade, an indescribable fervor immediately surged uncontrollably into his eyes.
"Pfft~"
As he stared at that sinister blood blade, he disregarded his own depletion and mobilized his origin vital blood. Then, he spat out one final mouthful of blood.
Buzz!
The instant that mass of vital blood landed on the colossal blood blade, which stretched ten thousand zhang long, a continuous humming blade cry rang out from its body.
At the same time, the Tong Ling Sect Ancestor in the distance also felt an intense sense of danger beneath that blade cry.
She had a feeling that if she were truly struck by that sinister blood blade, she might actually be severely
