At the same time, a group of people emerged from the passage ahead. All of them were employees working at the base. They walked unsteadily towards them, stumbling as they walked, just like zombies who had lost their souls in movies.
"They are zombies created by the Mind Bewitching Spell. It's another type of spell." Irene waved her right hand forward and a chilly aura exuded from her palm towards the zombies. As a result, the zombies, clearly under someone's control, collapsed on the ground one after another.
"Let's go back." Jacob stopped Irene, who was about to take a step forward. He shook his head and urged her to leave.
"Why? We've just come in. We have yet to retrieve the crystal energy," Irene asked in puzzlement.
"There is no longer any crystal energy inside. Those people were one step ahead of us." Jacob smiled bitterly and remarked, "Besides, we'll find nothing apart from the group of unconscious yet crazy zombies who would attack us in herds if we go in now."
