"There's definitely a problem!" Finding those hidden Saint-level Undead wasn't difficult—the real challenge was knowing where to look. Once Zhou Tian had that thought, the process of seeking out these Saint-level Undead became an easy task.
In no time at all, Zhou Tian discovered a small barrier within that area. As soon as he sensed it, without a word, he aimed a kick at its location.
"Boom!" A loud noise echoed as Zhou Tian's foot struck an invisible area, and he suddenly felt a surge of pressure. Then, without understanding what was happening, he was thrown back by an unseen force.
"You're tough!" Faced with such a formidable barrier, Zhou Tian wasn't certain he could easily destroy it. But he believed that, no matter how powerful this barrier might be, as an inanimate object, it couldn't outmatch a living being like him. If he failed to break the barrier with his first attack, he would make a second, and then a third. He didn't believe it could withstand his constant assaults.
