Great power output can create miracles.
Gu Youyou had no idea what was happening outside; she only focused on unleashing her full power.
Finally, she heard a cracking sound, like something was breaking.
A crack appeared on the Realm Stone, and as it spread, more and more cracks appeared, gradually revealing a transparent crystal within the core of the Realm Stone.
"A stone within a stone, interesting."
Before Gu Youyou could carefully study the hidden mystery of the stone within another stone, the stone chamber suddenly began to shake violently, and just like the Realm Stone, cracks began to form all over it.
"Damn, this Secret Realm is about to shatter."
Gu Youyou quickly used her Demonic Qi to wrap herself up completely, as the breaking of the Secret Realm would cause a significant spatial shockwave. If not careful, it could be life-threatening.
After the spatial shockwave, Gu Youyou reappeared in front of the gate of Tongyou City.
