"Congratulations. You've passed the test."
Himmel Soan was lost in his thoughts when he heard an authoritative voice that seemed to fill the space between heaven and earth.
The sound alone made one want to drop to their knees. The paintings on the wall started trembling violently. The expressions on the three hundred beasts also changed.
They seemed to be struggling to get out of the wall. Some of them already stuck their heads out.
Hum!
Seeing the monsters getting restless, the sound filled the cave again.
The barrier reappeared, covered by an ancient language that Himmel Soan didn't understand.
The monsters roared reluctantly and retreated into the mural.
"Who are you?" Himmel Soan asked.
His speculation was correct. Just like the nine-headed monster, all three hundred monsters in the mural could come out of the wall and become real creatures.
