The appearance of S-level Xenomorphs didn't differ much from A-level ones. Their exoskeletons had a faint white gloss, and they were slightly smaller than the A-level Xenomorphs.
However, Wang Ling could see from the cunning eyes of these S-level Xenomorphs that they possessed high intelligence. In the hierarchy of creatures, intelligence was more critical than pure strength. Humans could dominate the food chain because of their unique intelligence. If one were to assume that lions and tigers had intelligence similar to humans, it would be challenging to determine who would become the ruler of Earth.
Thus, Wang Ling remained cautious. He didn't know what tricks these Xenomorphs had up their sleeves as they circled around him. Those two S-level Xenomorphs occasionally emitted low growls, seemingly issuing some kind of command. Unfortunately, Wang Ling's translation device couldn't decipher their language, so he couldn't understand their conversation.
