Old Man of Heavenly Secrets's expression remained grim. He took a deep breath. "It's time to fulfill it."

"Wait!"
Wang Xuanfeng waved his hand. The glittering radiance in his palm surged, then directly pierced into Lin Xuan's dantian.
Lin Xuan's heart jolted. At this moment, he finally understood what this Heaven Severing Spiritual Opportunity was.
It was a rare wonder like the Essence of the Stars and Ten-Thousand-Year Spirit Marrow. Its function was simple: to enhance the strength of Martial Dao Pills.
