章 831: Chapter 831: Shocking Discovery

After flying around the top of the fire for a few laps, Peter Brown's face showed a sense of shock.

There were numerous pyramids scattered across Mars, which were, in fact, starlight cannons!

Looking at the various places, he saw a lot of remains where humans used to live, some houses that looked like prehistoric civilizations, and some ancient ones.

Peter even discovered some Heavenly Cave sites where cultivators had lived, but now these Heavenly Cave sites had collapsed due to the exhaustion of spiritual energy.

Looking at a huge stone wall in front of him, Peter could see traces of True Qi penetrating into the stone wall with his Divine Sense. This stone wall seemed to be inscribed with some characters by a powerful cultivator, but due to the passage of time, the characters left behind by even the strongest cultivators had been worn away.
