He had not expected the fourth level to be about comprehending the ultimate sword techniques.

Without hesitation, he immediately approached the first sword pillar and began to comprehend.

This large group of dark demonic shadows turned out to be the experts of the Ancient Corpse Demon race.

"Attack!"

Tens of thousands of experts from the Ancient Corpse Demon race, upon arriving above the Heavenly Emperor Secret Realm, attacked simultaneously, bombarding the protective shield of the secret realm.

Boom!

The protective shield of the Heavenly Emperor Secret Realm vibrated violently.
