Thus, Chen Ku and Qin Yuxian stood in place, watching Shan Lingguan walk into the wall.
They waited for the time it took an incense stick to burn.

Boom!
Sure enough, Shan Lingguan emerged from the Wind Raising Formation completely unscathed, surrounded by a gust of black wind, his aura seemingly even more powerful.
"Master?" Chen Ku inquired, "What was it like inside?"
Shan Lingguan stroked his beard with a smile and said, "It was a blessing. If other Seventh or Eighth Realm Martial Practitioners entered the Wind Raising Formation, they might not make it out. Fortunately, I have already mastered the 'Black Wind Body'; not only was I unharmed, but I also observed many 'Wind Central Array Patterns', inadvertently enhancing the power of my cultivation body by three more points."
At his age, unless he could break through to a greater realm, any slight progress was difficult.
Unexpectedly, this underground palace could bring such an opportunity.
