Creality slicing software astronomical build times

Hello all. I am very new to this but it is all very cool to me. I ran into a problem and I am not sure how to troubleshoot it. I downloaded a simple pull string helicopter off thingiverse. After running through the slicer software, the estimated build time is 131 hours. Relative to it’s size this seems insane. If I “run the simulated build”, there are long holds on one of the interior walls. I am hesitant to just “try it” and see if the pauses are a software thing that does not translate to the hardware. I am not sure how to break it down from here. Any advice?
