The glow of the altar grew increasingly intense, its formidable power forcing Zhong Yun and the others back to the edge of the platform. The black vortex resembled a giant beast with its abyssal maw gaping wide, ready to swallow them whole. At this critical juncture, Zhong Yun felt a gentle force wrap around him as Instructor Xuanfeng’s steady voice sounded in his ear: "Gather your focus, steady your mind!"
With that, spiritual energy surged around Instructor Xuanfeng, transforming into a golden barrier of light that shielded everyone behind him. The black vortex seemed to sense the threat, spinning frantically and engaging the golden barrier in a fierce clash. The impact left Zhong Yun and the others dizzy and barely able to stand.
Before long, the power of the black vortex gradually weakened until it vanished entirely. The golden barrier dissipated as well, leaving Instructor Xuanfeng looking pale, having clearly expended a vast amount of spiritual energy.
