As long as he didn't encounter Grotto-Heaven realm experts, Peng Jiuyuan should be enough to deal with them.
If not for the fact that Peng Jiuyuan was too weak, with the power of the Eight-Nine Arcane Art that was equivalent to half of Zhou Shu's realm, even ordinary Grotto-Heaven realm experts might not be his match.
Seeing that Zhou Shu was deep in thought, Peng Jiuyuan said carefully, "Lord, what do I need to do?"
The Peng family's ancestral teachings were that the person who made the Eight Trigrams Mirror glow would be the master of the Peng family.
But the Peng family's ancestral teachings didn't specify what they needed to do.

In fact, there was only so much he could do.
