Murong wasn't flustered by Long's absurd speed. She focused her mana onto her finger and thrust forward just as Long's fist arrived. The nine suns that followed behind Long rushed forward and crashed into each other. The force of those suns multiplied with each sun getting fused. When all nine suns merged, Long's fist was wrapped in an intense ball of flames.
When the intense ball of fire came at Murong, black cold energy accumulated on the tip of her finger. This black energy turned into a giant black drill that spun forward. Its sharpness made it seem as if it could pierce everything.
The energies from the Nine Yang Exploding Suns and the Nine Yin Abyssal Finger collided. Hot and cold pushed at one another. The stalemate lasted only a second. The black energy was engulfed by the scorching sun.
