After Alex dropped the mana core into the heart of the formation, a strong burst of golden light emitted from the formation on the ground and forced everyone else to squint their eyes in an attempt to adjust to the brightness.
However, it didn't last long, as everything returned to normal the next instant. When they finally opened their eyes, they saw that they were standing inside a ten-meter-wide golden barrier that was as tall as a small building!
"This is a formation, you can make formations?!" Amaya exclaimed in shock, and she turned to Alex, looking at him in a new light.
"We were taught a few things at the university," Alex replied with a humble smile.
At this moment, the magic beast finally arrived in front of the formation and without a moment of pause, they attacked the golden barrier crazily.
Bang! Bang! Bang!
Loud sounds filled the air for a moment as the magic beasts assaulted the barrier, trying all their might to reach the humans inside.
