Chương 642: Chapter615-The Treasure Left by Ocean Sage

As John sealed the Mystery Protector using his formidable Space Authority, the latter became acutely aware of the grave danger he was in. 

Despite transforming into a sphere entirely composed of Arcane energy, the Mystery Protector found himself unable to break the spatial seal with his potent Arcane power.

Left with no other choice, the Mystery Protector resorted to his final ace, a Sacred Relic in his possession. 

It was a gem imbued with boundless Mystery power, acquired in exchange from Darklord. 

"John, you've forced my hand! I'll show you that I have far more tricks up my sleeve than you do!" the Mystery Protector declared. 

As his words fell, he crushed the infinitely powerful Mystery gem, unleashing a torrent of Mystery power that merged with the Arcane energy.

The white sphere was instantly tainted brown by the power of Mystery, breaking through the Abyssal Prison's space seal crafted by John.
