The vice city lord's face changed as he turned to say, "Your Royal Highness, someone has set up an array at the cave gate, and is very powerful, such that I can't even get in."
Meng Lin's eyes grew cold as he waved his hands and said, "Step back you, I'll check this array out."
Meng Lin arrived before the cave, and closely inspected the defensive array before him, as his eyes filled with shock. He knew of the array and could tell with one look that this was a monarch grade array.
Meng Lin's eyes rolled around with thought. He was tracking the spiritual root, which is inside the cave, but the root couldn't have set this array, which meant that a self-cultivator who has captured the root must have placed the array to absorb the spiritual root.
Meng Lin's face changed when he realized this. He can't let anyone absorb that spiritual root, or else he would have returned with nothing.
