Xiao Lin was furious, but ultimately powerless. The man had actually managed to delay them. Even if it was only a very short time, the intensity of their battle had been felt from kilometers away. Those that were secretly transporting the energy stones had definitely felt the danger behind them, and decided to destroy the passage.
Since it had already collapsed, it was definitely too late to go after the energy stones. Thinking it over, Xiao Lin decided to abandon clearing up the passage. That was because he suddenly understood why the man had spent so much effort digging the passage. It was obviously not to transport energy stones. If enemy forces appeared in the heart of the royal city, then the consequences would have been dire, so blocking the way like that was a good idea.
