Everyone was laughing except Gansus and Ma Xiaoru. Ma Xiaoru wasn’t laughing because what Wang Tong said was actually his ability to foresee danger, which is also his sense of the menace. Most inferior Zergs like Skulk Zergs were not very good at hiding their urge to kill; still, it would take a lot of practices for a person to identify the menace around oneself, especially on the murderous battlefield.
Gansus didn’t laugh as well because he knew only a veteran would say that. Only someone who had numerous near-death experiences would know how to deal with Skulk Zergs. This wasn’t something printed in the textbooks, he had killed tens of them before, and it all came to the “sense of smell” of a soldier!
