Chapter 687: Reviving Heavenly Yin

Qin Mu took in a long breath and suppressed the palpitation in his heart.

To gather Goddess of Heavenly Yin's soul, it was impossible with just Soul Guide.

Soul Guide was a divine art that could guide one's soul back from Youdu, allowing the soul to return back into his corporeal body.

Meanwhile, Goddess of Heavenly Yin was eaten until only her skin was left. Her soul might also have been eaten and turned into part of the black sand in Heavenly Yin World.

If he wanted to gather her soul, he would have to make some changes to Soul Guide!

Qin Mu was also 'enlightened' by the god of Founding Emperor, and he thought of changing Soul Guide to gather Goddess of Heavenly Yin's soul.

As long as Goddess of Heavenly Yin's soul returned, she could block the control Mingdu had on the darkness of the Great Ruins.
