In the next moment, the demonic qi surged upon the blade of the Billion Demon Sword, blood-red light burst forth, and the black Demon Sword slowly floated up from Lin Feng's palm.
Within the Billion Demon Sword, it seemed as if a strong suction force was emitted, absorbing the invisible slaughter mystical technique from the summit of the Mystical Technique Mountain.
Lin Feng looked quietly at the Demon Sword, a trace of a smile flashing in his eyes; could he comprehend the slaughter mystical technique from the Demon Sword?
If it were truly so, that would be excellent!
After a short while, Lin Feng pondered slightly before his fingers continuously moved toward the Billion Demon Sword, shooting out strands of finger light.
Within each strand of finger light was imbued his intense spiritual thought.
As the spiritual thought entered the Billion Demon Sword, it immediately formed a powerful spiritual imprint.
With this imprint, Lin Feng could control the sword.
