The Violent Ape King's Coiling Dragon Staff and the Ghoul Corpse King's Ten Thousand Corpse Banner, these two high grade weapons, fly about erratically. Every strike is powerful enough to destroy a star, and they fiercely hammer upon Lin Zhen's Sword Palace.
But all of this had no effect whatsoever. The Sword Palace, being a high-grade flying palace and the container for the Eighteen Divine Swords, was far more solid than they could have imagined.
Know that flying palaces are capable of releasing an energy shield.
A faint light screen enveloped the palace, flickering intermittently, and blocked all their attacks.
However, the Sword Palace had just emerged from the volcano, and having been dormant for who knows how long, it seemed it didn't have much energy left.
"Damn it! Is this high-grade palace really this strong? It can still block an attack even when it's almost out of energy!"
