Boom!
A loud sound echoed throughout the center of the fallen divine kingdom.
Gladstone smashed the last layer of the barrier with one punch.
"Hu! Hu! Hu..."
Gladstone panted heavily.
Even for him, smashing ten layers of the barrier was a huge expenditure.
Moreover, Joelson did not give him a chance to rest. As long as he stopped, Joelson would immediately repair the barrier, so he could only continue to attack with all his strength.
What puzzled him the most was that for some reason, the sturdiness of Joelson's barrier was beyond his imagination.
Normally speaking, at the level of a demigod, attacks were far stronger than defense.
In battle, a barrier wouldn't be able to block an opponent's full-force attack.
However, he had never seen a barrier of arcane mysteries as sturdy as Joelson's.
Even in Supreme Academy, he had only seen stronger defenses on students who cultivated defensive arcane magic.
