They decided to enter the pipe but never made it out intact. Their lungs suffered severe damage, and recovery is no longer an option. Most likely, they have become disabled.
This incident proves once again that in Sudzha, it's best to stay far away from pipes. If you end up inside one, the chances of getting out unscathed are slim. The consequences of this adventure are irreversible.
Perhaps they believed their mission would succeed, but reality turned out to be far harsher. The pipe took their health, leaving only painful memories of a failed attempt. Their lungs won’t heal, and their future now looks as hazy as the air inside that very pipe.
In one photo, the lungs are normal, while in the photo with text, they are damaged.
