Chapter 16 starts with the MC's second test combating the wild boar in the arena. After barely avoiding paralysis caused by fear, Filina manages to defeat the wild boar by slicing it in half. The third test begins and she has to fight more of the suckers. As she does so, she recalls several of her previous deaths, moving to a flow state in the process. (In the second life as Filina, the MC was apparently strangled by Henry.) When the dust settles, she is triumphant but thoughtful. However, as Henry rocks up for his own test, several candidates accuse her of cheating and she heads to the lab for an investigation.
That was an action-packed chapter. Kind of interesting seeing the MC get in the zone a bit. However, I wish the author took more advantage of the concept of combat-based tunnel vision. Combat-based tunnel vision is a real phenomenon, as the human body pushes blood to areas deemed important to survival for ancient ancestors. (We end up focusing on a single threat ahead of us.) Instead, the author moved to a more theatrical storytelling element which is primarily used to inform the reader of certain things about the relevant character. Whilst both storytelling methods have merit, the consideration is time. If the time for said musings doesn't mesh with the time of the threat, then it feels more like a DBZ fight. Ergo, I think the combat-based tunnel vision idea would fit a bit better for the action sequence. (personal preference, obviously)
