章 520: Chapter 518: The Most Popular Person among Pill Masters_1

Lu Xuan looked at the Bone Slaying Sword Grass in the spirit soil, intending to store it in the Gluttonous Insect Pouch, when a thought occurred to him.

His spiritual sense slowly seeped into the spiritual seed.

Instantly, he felt as if he had entered a world of slaughter, where the sword intent surged to the heavens and murderous intent was infinite.

The Clear Sword Heart in Lu Xuan's dantian spun slightly, and under his spiritual sense, the murder sword intent underwent subtle changes.

Originally profound and abstruse, difficult to grasp, it now left traces in the depths of his sea of consciousness that resembled antelope horns, making it easy to comprehend.

When his heart and mind gradually began to tire, Lu Xuan withdrew from the world of murderous sword intent, and standing quietly in place, he seemed to have gleaned some insights.
