2 days later,
Both Jennifer and Tina observe their surrounding area. If you look around them, then other than the darkness, you would not be able to see anything.
As you can predict both of them are searching for Monsters around the night time as Sam decided that it will be good for his students if they get used to fighting during the night time.
In these 2 days, they already start fighting those level 13 Monsters and already get used to fighting those Monsters.
Jennifer did not have that much problem fighting those Monsters, but it was different for Tina.
She had quite a tough time fighting those Monsters as those Monsters were in the same power level as her. Even though those Monsters did not reach the limit of their level but still because of their number, they can get an advantage over Tina.
