At this moment, Lin Bai did not know that because of him, the people who had come with him had all been thrown into the prison of the City Lord's Estate. He was studying the ordinary small cauldron in front of him.
Logically speaking, it was impossible that there were no changes after the commotion just now. However, that was the truth. The small cauldron did not have any reaction. If Lin Bai had not held it in his hand, he would not even have noticed that it had become heavier.
"That huge formation just now almost sucked all the spiritual energy in my body dry. What exactly was that thing..."
Lin Bai muttered to himself. He frowned and fell into deep thought. The danger to his life just now was not a joke.
Under such a dangerous situation, he had a premonition that if he had not summoned the black cauldron later, he might really have been sucked dry of spiritual energy by the mysterious array formation and the altar.
