章 661: An Arm

A dark world lay behind the stone door. Luo Qiqi stepped forward and hurled a few Night Illumination Pearls down to light up the interior.

The further the duo walked down the stairs, the louder the flow of the stream above them sounded.

Even though they were beneath a stream, it didn't feel humid at all. On the contrary, it felt extremely dry. On top of that, the air seemed to be getting fresher and richer in spiritual energy.

"The spiritual energy is drawn in from the stream above. Most probably, a unique Spirit Gathering Formation was inscribed on top," Luo Qiqi uttered with a hushed voice as she studied the surroundings.

"Un." Zhang Xuan nodded.

By building a huge Spirit Gathering Formation in the river, they would be able to draw in spiritual energy from the surface discreetly.

With this influx of spiritual energy, this underground chamber would become an excellent location to cultivate in.

Jiya!
