Looking at the two huge sword pillars in front of him, Yang Xiaotian was surprised.
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.
Just as Yang Xiaotian was contemplating the ultimate sword techniques of the fourth level, suddenly, a large group of dark demonic shadows arrived in the sky above Heavenly Heart Island.
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.
However, with the shield in place, inside the Heavenly Emperor Palace, Yang Xiaotian and the others did not feel the tremors.
