The scene before her eyes was bloody enough.
The overwhelming smell of blood almost made her vomit, but what she found most unbearable was that she was almost suffocating.
No, it wasn't suffocation, but hyperventilation.
Because the first glance after opening the door was too shocking, leading her to breathe too rapidly, causing her lungs to intake too much oxygen and insufficient carbon dioxide, thus resulting in hyperventilation.
Hyperventilation felt a lot like suffocation. If not managed properly, the consequences would be just as deadly as suffocation.
Gu Yi'an was very aware that her current situation was hyperventilation, akin to desperately gasping for air, with her alveoli nearly bursting, yet still feeling as if she were suffocating.
Many people in such a situation, feeling as if they couldn't get enough oxygen no matter how they breathed, would increase their breathing frequency, inhaling and exhaling rapidly.
