Upon hearing Xie Aibiao's words, Nie Zhenbang's mouth revealed a hint of curvature; by this point, matters had essentially settled into place.
At this moment, Xie Aibiao's slickness was fully exposed. Not everyone has the skill to adopt his approach of offending neither side.
Speaking plainly, playing both sides is like stepping on two boats. From a purely physical standpoint, if you are stepping on two boats moving parallel, this is without a doubt more comfortable and stable than standing on a single boat. However, once the boats go their separate ways, or even head in opposite directions, the person standing between them may be torn in half by the force. Similarly, there is also the possibility of falling into the water and drowning.
Therefore, whether from the perspective of physics or political science, this method is a high-level technique not easily managed by just anyone. This proved the extent of Xie Aibiao's slickness.
