Chapter 1663: Kong shi's Cultivation Technique

"Recording?"

Taking a closer look, Zhang Xuan noticed that the silhouette was cultivating. Surges of spiritual energy were gushing into his body, circulating in a certain pathway.

"This is… Kong shi?" Zhang Xuan's face twitched.

Rather than a human, the silhouette looked more like a burnt sweet potato instead. If not for Luo Ruoxin's reminder, he would not have thought that it was a human… Was this blurred black thing really Kong shi?

Seeing that Zhang Xuan was distracted by such small details, Luo Ruoxin sighed helplessly. "The recording will only appear once. It's only triggered due to your successful breakthrough as a Celestial Saint. This opportunity won't come again if you don't pay close attention."

Hearing those words, Zhang Xuan hurriedly focused his attention on watching the movements of the black shadow.
