Ren Xiaosu looked at the little black book in his hand. Since the Pyro Company soldier next to him could recognize it at a glance, it showed that a precedent had been set for this black book among the Pyro Company troops. He asked again, "What other uses does this little black book have other than allowing the holder to move around 3rd Division without any restrictions?"
"Oh." The Pyro Company soldier thought the commander was probably too busy and did not have time to explain to Ren Xiaosu what it was used for after handing him the little black book. Thus he explained, "This is Commander P5092's ID. Seeing it is equivalent to seeing the commander. You could say that other than commanding the troops to battle and other important things like that, there's nothing else you can't do with it."
