"Hmm?" At this moment, Lin Rui's expression froze as he looked toward the south.
He sensed a very powerful spirit mechanism aura emerging at the location of the Second Martial Arts Hall in the core zone of the dock base.
The towering ether spiritual tide surged in all directions, like waves covering the entire core zone of the dock base, until it was blocked by the protective isolation wall of the outer layer of the core zone.
At the same time, there was another powerful and mysterious, imposing conceptual power that enveloped the entire base.
Sima Lin and Huang Fuqing both sensed this, glancing at each other in surprise and doubt.
In their minds, a thought occurred—Longevity level!
The ether tide that erupted over there is indeed very strong, but due to various experiments, powerful ether tides frequently occur at Rui Fang's Armored Biological Research Institute and Forest Heavy Industry Research Institute.
The problem is the concept accompanying this tide that has spread!
